Utility Magazine November 2023

Summer is just around the corner, and it’s hard to believe that this is the final edition of Utility Magazine for 2023. As we shift towards El Nino weather patterns, utilities across the country are preparing for reduced rainfall, and hotter, drier conditions leading to elevated bushfire risks. Climate change only exacerbates these symptoms, and the transition to renewables is a major focus for all sectors.

Water security is one of the most essential services that utilities can provide to their communities, and it remains an ongoing focus across the sector. In this November edition we cover some of the major projects that water utilities are undertaking to improve their supply network; including the Fitzroy to Gladstone Pipeline, which aims to address the single source water supply risk from Awoonga Dam, and SA Water’s recently unveiled Oodnadatta desalination plant that is providing clean drinking water to the remote First Nations community.

Over in the energy sector, the transition to renewables is still a key focus, particularly as the closures of more and more coal fired power stations have been announced. Storage is one of the key aspects to ensuring that we get the most out of the renewable energy that we generate, and we spoke with Genex Power about its recently completed large-scale Bouldercombe battery energy storage system (BESS) –the first 100 per cent commercial battery project in Australia.

The water sector also has a role to play in the race to net zero, and utilities are turning towards renewable energy sources to power their assets. To meet these targets, North East Water has invested in a 3MW solar farm to power its Wodonga Wastewater Treatment Plant, which aims to reduce the

corporation’s carbon footprint by 20 per cent every year.

Efficient operations that produce minimal waste are also an essential step towards a climate friendly future. To achieve this, utilities are moving towards a circular-economy approach. We spoke with South East Water’s Strategic Research Manager, Dr Li Gao, about the utility's recent study on microplastics and how effectively different water recycling methods can remove them.

On the customer side, consumers are feeling the pressure as cost-of-living increases and interest rates soar. Anna Collyer, Chair of the Australian Energy Market Commission discusses how the energy transition is changing the way customers interact with energy in their homes, and how the implementation of electricity smart meters can both assist with lowering energy bills and reducing strain on the grid.

With a changing landscape comes excellent innovation, and Australian utilities across all sectors are constantly raising the bar for improvement and sharing that knowledge so that we can all work towards a brighter future. It is our great privilege at Utility Magazine to acknowledge their success and we can’t wait to see what unfolds in 2024.

As

population continues to grow, maintaining and upgrading essential infrastructure is a must. More than 5 million people already live in the city, which means sewerage systems need to be able to handle a staggering amount of waste.

THE ESOO CALL TO ACTION

As Australia transitions towards renewables and away from coal-fired power, the Electricity Statement of Opportunities (ESOO) has predicted that we are likely to see larger gaps in energy reliability. Here, we take a look at these forecasted challenges and how we can address them.

Once a year the market operator, AEMO, issues its Electricity Statement of Opportunities, (ESOO). The ESOO considers, over its ten-year forecast horizon, the entry and exit of generation, the ability of interconnectors to get that generation to customers, and the contributions of demand side participation in the market. The forecast considers how much of the time customers will not get energy. It is measured in unserved energy (USE) and it is used to set the standard for how reliable a system we should be aiming for. The Reliability Standard is 0.002 per cent of USE. This implies we can expect to have enough supply to meet demand 99.998 per cent of the time, in every region of the NEM, every year.

Continuing the trend from recent years, and despite an interim update to the ESOO in February 2023, this year’s ESOO indicates larger gaps in reliability. Figure 1 shows the central scenario forecast that the reliability standard could be breached in 2024/25 in New South Wales, followed soon after by Victoria, South Australia and Queensland.

A forecast showing USE rising above the Reliability Standard is generally considered to be undesirable, and requiring something to change in the real world to make sure the forecast world doesn’t eventuate. For this reason, most of the commentary has opined on what should change in the real world to address the forecast gaps. These changes vary between generation, network or demand.

Highlighting the role of the ESOO to provide information designed to prompt decisions that make the forecast out of date, the New South Wales Government response to the NSW Electricity Supply and Reliability Check-up suggests it will work with Origin Energy on the extension of Eraring’s operation beyond 2025. Indeed, the public posturing for what will be a very challenging commercial negotiation has begun, with the New South Wales Government noting in its response that it considers Eraring to be a profitable asset with a decade left in its technical life.

Put in context, this ESOO is a starker and more immediate warning than previous forecasts. In the good old days (say five to ten years ago), an ESOO would highlight a benign gap in a future year in a NEM region, and this would prompt a market (or at times non-market) response. The following year would roll around and the ESOO forecasts would have new information, new plans and committed investments. This would result in a forecast that essentially had fixed, in the real world, the problem faced in the previous year’s modelled world.

We are now in materially different real-world circumstances, with a tighter supply/demand balance and a

constrained network. The most recent ESOO that showed no significant breach of the Reliability Standard under the central case was in 2020. This is shown in Figure 2.

Since 2020, a succession of announced early coal generator retirements proceeded to bring forward the ESOO’s forecast gaps in USE across regions. This started in the 2021 ESOO, in Figure 3.

And continued in the 2022 ESOO, shown in Figure 4.

As we can see, the cliff face of USE is moving closer to the present, and the precipitating factor is the closure of existing coal, gas and diesel generation. Some 6,730MW of this generation is expected to retire over the next decade.

Let’s take a look at what needs to happen in the real world to address these significant challenges forecasted in the ESOO modelled world.

GENERATION AND STORAGE

A significant pipeline of committed generation and storage investment is expected to progressively come on-line over the next decade, totalling more than 20GW of capacity.

This includes:

• Tallawarra B (320MW) in New South Wales from November 2023

• Kurri Kurri Power Station (750MW) in New South Wales from December 2024

• Kidston Pumped Hydro Energy Storage (250 MW/2,000MWh) in Queensland from February 2025

• Snowy 2.0 (2,040 MW/350,000MWh) in New South Wales by December 2029

• Borumba Pumped Hydro (1,998 MW/48,000MWh) in Queensland from June 2030

• More than 5,241MW/11,054MWh of utility-scale batteries, including Eraring Big Battery, Hazelwood Battery Energy Storage System (BESS), Orana BESS, Swanbank BESS, Torrens Island BESS, and Wooreen BESS

• Numerous renewable energy developments across the NEM, including 4,918MW of wind generation and 5,212MW of utility-scale solar generation

These changes that we ‘know’ are happening are considered in the central case. Reflecting state governments taking a more active role over recent years, jurisdictional schemes are likely to incentivise further new generation and storage. These schemes include the federal Capacity Investment Scheme, New South Wales Electricity Infrastructure Roadmap, Victorian Renewable Energy Target Auction 2, Queensland Energy and Jobs Plan, and the South Australian Hydrogen and Jobs Plan.

Connecting all this new generation and storage, and getting this new capacity to market, requires new transmission.

TRANSMISSION

Transmission is an important enabler of the transition to renewables. It facilitates generation being shared across states and into load centres. This is increasingly important as we shift to more weather dependent generation, where renewable resources may be greater or lesser at any given time across different parts of the NEM. The committed transmission developments considered in the central case in the ESOO include:

• Project Energy Connect linking South Australia to New South Wales and Victoria. The first stage of this project will start its transmission commissioning in early 2024

• The Waratah Super Battery and associated transmission upgrades in New South Wales will help meet the reliability requirements in New South Wales

• Western renewables Link in Victoria will better connect renewables in north west Victoria to the Melbourne Load centre

• Central West Orana renewable Energy Zone will deliver transmission to connect more renewables in NSW New transmission plays a critical role in the reliability of a transforming power system. While planning and regulatory processes rightly focus on the net benefits of projects, it is also important to consider these projects in the broader context of system reliability and the decarbonisation of our economy

A WORD FROM WSAA

In August 2023 at a launch in Canberra, WSAA hosted the Minister for Environment and Water, Tanya Plibersek, and launched Blue x green = thriving: A progress report on water's role for thriving communities.

The progress report continues from our earlier work Blue + Green = Liveability, with the intention to renew the ambition for the water industry in advancing our understanding of water as a key enabler for thriving communities.

The water industry is increasingly being recognised as having an expanded role beyond traditional drinking water, wastewater and stormwater services. This expanding role embraces water as an enabler of innovation, and integral to sustainability and economic productivity. As such we are committed to harnessing the transformative potential of water services to shape a resilient, sustainable, and thriving future for all.

Through the progress report WSAA explores, in detail, how water resources can be leveraged in innovative ways to enhance both urban and regional liveability, stimulate economic productivity, and enhance precious natural ecosystems. We showcase some of the latest initiatives and innovative solutions already being undertaken across 15 case studies.

The importance of blue and green infrastructure in progressing liveable to thriving communities is continued. Given the experiences through the COVID-19 pandemic and ongoing climate change impacts, we highlight the significant value that people place on water's role in ensuring the productivity of both our economy and communities.

The next wave of reform involves the pursuit of recommendations from WSAA’s previous report, Blue + Green = Liveability, where progress is still occurring, as well as setting additional key policy reform objectives. The industry is wanting to build on the successes that have been made to drive a more ambitious narrative of what is possible in transitioning from liveability to thriving.

WSAA and the urban water industry look forward to working with all levels of government to better understand and promote water’s contribution to a thriving future. This report invites all stakeholders, from policymakers and industry leaders to community members and researchers, to embrace the transformative role water plays in cities and regions as they seek to thrive.

TASWATER ANNOUNCES OPENING OF UPGRADED WATER TREATMENT PLANT

TasWater has officially opened its upgraded Bryn Estyn water treatment plant, set to ensure water security for 200,000 customers in southern Tasmania.

TasWater’s said its largest ever capital works project – delivered on time and under its $243.9 million budget – will provide safe, clean and reliable drinking water for generations of Tasmanians.

TasWater Chief Executive Officer, George Theo, said the opening marked a major milestone for Greater Hobart.

“This is a landmark day for southern Tasmania,” Mr Theo said.

“The upgrade of the Bryn Estyn water treatment plant ensures safe, clean drinking water will be available for generations of Tasmanians from Kempton to Snug, and New Norfolk to Sorell.

“Drinking water for around 200,000 customers is in safe hands with the

new plant able to treat 160 million litres of water per day.

“The plant has been designed for future population and economic growth in the region, with the potential to be expanded to treat another 40 million litres of water per day if required.

“During construction the project employed around 1,500 people directly and 500 indirectly.

“At its peak, around 150 people were working on site every day, generating great economic benefits for Tasmanian businesses across the state.”

Water from Bryn Estyn winds its way through 433km of water mains and into 145 reservoir tanks before reaching the taps of customers in Hobart, Glenorchy, Kingborough, Brighton, Derwent Valley, Southern Midlands, Sorell and Clarence.

TasWater’s Head of Water and Environment Services, Fran Smith, said the upgrade expanded the capacity for the organisation to deliver greater

volumes of high-quality, safe drinking water for Hobart.

“To be able to treat and deliver 160 million litres of water every day, with every litre meeting the Australian Drinking Water Guidelines, is not a small task,” Ms Smith said.

“Each drop of water that has passed through Bryn Estyn has been subjected to a treatment process that includes filtration, ozone, absorption using activated carbon, chlorination, and now UV disinfection for an extra layer of treatment.

“Just last year alone across the state we undertook 273,000 tests to ensure Tasmanians could turn on the tap with confidence knowing their water is absolutely safe to drink.”

“It’s an exciting day for our entire team.”

TasWater is currently delivering a planned ten-year, $1.84 billion capital investment program for completion in the financial year 2025–26.

WA GOV AWARDS $1B IN CONTRACTS FOR BIG BATTERIES

More than $1 billion has been awarded in contracts by the Western Australian Government for the Kwinana and Collie big battery storage systems.

Contemporary Amperex Technology Co. Limited (CATL) has been contracted to supply about 300 EnerC Plus, containerised liquid-cooling battery systems for Kwinana Battery Stage Two, and about 650 EnerC Plus for Collie.

Power Electronics will deliver 72 inverters for the Kwinana battery and 160 inverters for the Collie battery.

Kwinana Battery Stage Two will provide 200MW of power with 800MWh of energy storage. Construction started on Kwinana Battery Stage Two in June and is estimated for completion at the end of 2024, supporting 160 jobs.

The Collie battery will be the biggest in Western Australia providing 500MW with 2,000MWh of storage. It will create about 500 jobs during the peak of construction.

The batteries will support more renewables by storing wind and solar energy generated during the day and delivering it back to the system during high-demand periods.

The contracts are part of the Western Australia Government’s $2.8 billion budget commitment to delivering renewable energy projects.

Western Australia Premier, Roger Cook, said “These contracts, worth more than $1 billion, represent a major and important investment by our Government into WA’s cleaner, reliable and affordable energy future.

“Battery energy storage systems will play a key role in our decarbonisation plans, storing excess renewable energy generated in the day and discharging during times of high demand.

“We’re putting Western Australia on the path to becoming a global green energy superpower, which is good for jobs, good for the environment, and will keep our economy strong into the future.”

SYDNEY WATER COMMENCES $185M WASTEWATER NETWORK UPGRADE

Sydney Water is conducting upgrades to the Richmond wastewater network to help accommodate the rapidly increasing population, with the construction upgrade expected to create 200 job opportunities.

The project will include a new wastewater pumping station and the construction of a new seven kilometre main which is expected to transfer wastewater from North Richmond to Richmond.

The improvements are in keeping with Sydney Water’s goal of building critical water and wastewater infrastructure to enable the construction of future dwellings in Greater Sydney.

Senior Project Manager, Greg Cable, said that the planned works will play a major part in ensuring a more sustainable future.

“Growth is set to increase by 70 per cent over the next 30 years. The completed upgrades will help future proof the region’s rapidly growing population.”

The project will contribute to circular economy benefits by expanding water recycling capacity at the site and the production of biosoli matter for reuse.

Upgrades to the Richmond Water Recycling Plant are expected to be completed in 2026.

BASSLINK TO BE TRANSITIONED TO A REGULATED ASSET BY AER

The Tasmania State Government has welcomed an announcement by APA Group that it is progressing plans to make Basslink a regulated asset with the Australian Energy Regulator (AER).

The state government said Tasmania will be better off as a result of the transparent regulatory process and that it will bring Basslink in line with all other interconnectors in the National Electricity Market (NEM) as a regulated asset.

Tasmania State Minister for Energy and Renewables, Guy Barnett, said regulation of the asset will ensure that Victoria pays its share of the ongoing costs of Basslink and will help the state government to deliver on its energy plan to benefit all Tasmanians.

“Basslink’s transition to a regulated asset would bring surety to the sustainable flow of electricity between Tasmania and Victoria,” Mr Barnett said.

“It will also mean that, for the first time, Victoria will pay for a share of the benefits accruing from the interconnector.

“Regulation provides an open, transparent process around driving those outcomes.

“The Tasmanian Government wants APA Group to operate Basslink efficiently and effectively and to continue to invest in

the link, and asset regulation ensures this for the long-term interests of Tasmanian energy consumers.”

Basslink started trading in 2006 and, with arrangements overseen by the former Tasmanian State Government under Paul Lennon and Michael Aird, Tasmania was the only state responsible for the ongoing costs of the asset.

With APA Group purchasing Basslink in October 2022, it is now able to progress the regulation process with the AER.

“APA has proposed a market size approach to cost allocation that will see Victoria wear 90 per cent of the cost allocation. The Tasmanian Government will submit to the AER that the market size model is adopted, noting that all options presented see Tasmania being better off,” Mr Barnett said.

“Our Tasmania First Energy Guarantee ensures that Tasmanians will continue to have among the lowest power prices in the country, and this is another step that helps deliver this.

“Along with the development of Marinus, which will also go through the open and transparent regulatory process with the AER, this is setting up Tasmania for decades to come.”

Mr Barnett said the regulatory processes will have multiple opportunities for public consultation and input, with the AER expecting a determination in late 2024.

WYANGALA DAM PROJECT CANCELLED

The New South Wales Government has announced that it will not be going ahead with the Wyangala Dam Wall Raising Project, due to the severe predicted environmental impacts and the billions of dollars in projected construction costs.

New South Wales Minister for Water, Rose Jackson, said both the project’s Final Business Case and an extensive independent review by Infrastructure NSW have recommended not raising the dam wall because it doesn’t stack up financially or environmentally.

“Robust investigations show that while raising the wall by 10m is technically feasible, it could cause substantial and irreversible environmental impacts,” Ms Jackson said.

“Hydrological modelling also found raising the wall, with a 5m flood mitigation zone, was also likely to have devastating impacts on the internationally significant downstream environment, resulting in excessive biodiversity offset costs.

“The other major issue is the billions of dollars spent to build the dam wall. We have a responsibility to taxpayers to only fund infrastructure projects that provide maximum bang for the buck and, in this case, the capital costs are too high, and the benefits are too low.

“While Wyangala is not viable, I recognise the challenges of water security, reliability and flood mitigation for Lachlan communities do not go away. We know there’s a drought knocking on our door threatening the water security of towns

across New South Wales, which is why we are reviewing our strategies as a priority.

“The New South Wales Government is now taking action because we know the region needs a multi-faceted approach to protect against uncertainties and balance the competing needs of our environment, towns, and farmers.”

The New South Wales Government will be seeking feedback on how it plans to address these issues in the draft Lachlan Regional Water Strategy, which will go on public exhibition before the end of September.

It will allow people to have their say on water security and will put forward a shortlist of proposed actions to help support local communities, so they’re in the strongest position to manage a more variable climate over the coming decades.

Ms Jackson said the decisions made about the future of water in the Lachlan region will be based on evidence and state-of-the-art climate modelling.

“We want to support economic growth and balance different water needs, ensuring there’s the right amount of water for the right purpose at the right time,” she said.

“I encourage everyone across the Lachlan region to provide their input when the draft strategy goes on exhibition, because feedback from councils, industry and the community will play a vital role in helping us determine the best way forward.”

ENERGY NETWORKS AUS 2023 AWARD WINNERS ANNOUNCED

The winners of the 2023 Energy Networks Industry awards have been announced at the Energy Networks Australia (ENA) annual dinner on 19 September, recognising key industry members.

Ausgrid was announced as the winner of the Energy Network Industry Innovation Award 2023, which recognises leadership in the design, development and application of a ground-breaking Australian energy network initiative.

Endeavour Energy has taken home the Consumer Engagement Award for 2023, which recognises an Australian energy network that demonstrates best practice consumer engagement.

Ausgrid received the award in recognition of its program, Project Edith – dynamic network pricing for market active consumer energy resources.

Project Edith was a collaboration with Reposit Power, an aggregator that orchestrates customer resources into Virtual

Power Plants that can participate in the NEM. The objective is to showcase how, through dynamic network prices, distribution networks can unlock more value for and from customer energy resources.

ENA CEO, Dominique van den Berg, said that the project took a collaborative approach, co-designing alongside project partners and engaging with stakeholders from across the industry.

“Australia’s energy networks are world leaders in innovation and Project Edith shows networks taking a more customer centric approach to innovation and are engaging closely with a wide range of stakeholders to ensure customers are taken on the journey to net zero,” Ms van den Berg said.

“This project demonstrates how networks can utilise the grid in an economic manner while at the same time connecting with customers along the network.”

Project Edith is named after Edith Clarke, a pioneer of electrical power system analysis, considered the ‘Mother of Invention’ at GE alongside Thomas Edison and Nikola Tesla.

Endeavour was presented its award for its project, Power Together – Collaborating on Our Energy Future.

Endeavour Energy’s program was centred around fulfilling a goal to deliver a Revenue Proposal for 2024-2029 that balanced the current and future needs of its customers and was supported by key stakeholders.

Endeavour delivered an engagement program that was designed to embed an enterprise-wide, customer-centric culture, led from the top.

Ms van den Berg said that Endeavour’s engagement strategy displayed a strong desire to fully embed customer needs within the Revenue Proposal.

“Engaging with customers on the type of services they expect from their network service providers is a critical component of leading consumer engagement best practice.”

Energy Consumers Australia Interim CEO, Jacqueline Crawshaw, said consumers want to be part of Australia’s energy future, and including their voices and designing for them will be vital for a successful energy transition.

“Key to this, and to ensuring better outcomes for consumers in general, is better engagement practices,” Ms Crawshaw said.

Endeavour Energy’s consumer engagement program spanned five co-designed engagement phases and involved more than 1,800 customers and stakeholders representing 124 organisations. Over 150 employees played an active role in engagement, committing 2,770 hours of face-toface engagement.

HOW TO CHOOSE THE RIGHT TORQUE LIMITER WHEN OPERATING VALVES

It's easy to imagine that a stuck or very difficult valve is the primary reason for purchasing such a tool. However, this is not necessarily the best reason to use a portable valve actuator. Here we discuss the key considerations to take into account when choosing a torque limiter.

Too much torque can cause serious damage to the valve, and often results in it needing to be replaced. Torque limiters are designed to ensure that torque never reaches these critical levels, and can help protect expensive machinery.

WHAT IS THE MAXIMUM TORQUE THAT CAN BE APPLIED TO A VALVE HANDWHEEL?

The easiest way is to refer to the valve specifications, when available, and find the maximum acceptable stem torque (MAST). If you don't have this information, you have to go gradually, with rotation tests in one direction and then in the other. In any case, a completely blocked valve actuator is often a sign that it is time to replace the valve itself.

HOW TO BE SURE NOT TO EXCEED THE MAXIMUM TORQUE APPLIED TO A VALVE HANDWHEEL?

A torque limiter integrated in the portable actuator should be used. There are several systems of torque limiters, and it is important to choose the right one.

USE STALL TORQUE, WHEN POSSIBLE

The first and simplest torque limiter is therefore the maximum torque that the actuator can reach.

In the case of a pneumatic actuator, the stall torque is itself modifiable according to the operating pressure, and can be brought to stall as often as necessary without causing any damage to the actuator itself.

In the case of a gas actuator, there is also a maximum torque at which the motor will stall.

In the case of a portable electric actuator, wired or battery powered, the problem is different. In fact, an electric motor is very likely to be damaged when it is brought to stall.

MC89 AND JA73 MODEC BATTERY ELECTRIC ACTUATORS: USE THE INTEGRATED TORQUE LIMITER

The Modec MC89 (easy and standard duty) and JA73 (standard and heavy duty) ranges of battery powered portable actuators incorporate torque limiting systems by default, which already meet the majority of requirements.

The MC89 has an electronic system for setting the maximum torque, which ensures that the machine will stop as soon as the chosen torque is reached.

The JA73 has an intelligent clutch system that allows the maximum torque to be set at 100, 80, 60, 40 or 20 per cent of the maximum torque indicated in the catalogue. When this torque is reached, the clutch disconnects the engine from the integrated gearbox.

ADJUSTABLE MECHANICAL TORQUE LIMITER

The systems described above are effective in most cases, but sometimes greater precision is required, or the adjustment range must be continuous rather than stepwise. Also, the gas portable actuators (PY68) do not have a maximum torque setting system.

To meet these specific needs, Modec has developed a mechanical adjustable torque limiter, which can be fitted as an option to any portable actuator in the range, and allows manual adjustment of plus or minus 40 per cent in relation to a median value. Once the set torque is reached, the motor disconnects from the gearbox.

Regardless of the type of Modec portable actuator selected, there is a solution to control the torque and thus guarantee the safety of the equipment.

SOLVING PROBLEMS UNDERGROUND FOR THE MOLONGLO VALLEY PROJECT

In Australia’s capital, key transmission work has been underway, where new housing subdivisions in the Molonglo Valley have required the relocation of 1,500t or 58km of 132kV cables underground and the removal of above ground transmission towers. Works such as these have many moving parts, requiring clear, upfront communication and a unified plan with all contractors to ensure works keep moving and are completed safely. Zinfra was awarded tender for the project and has been on the ground in Canberra, working on relocating Evoenergy’s Molonglo transmission assets since 2022.

The Molonglo 132kV Relocation Project is part of the ACT Government’s Suburban Land Agency work on subdividing the region for future homeowners. Zinfra brought its expertise to Molonglo, where the team worked alongside principal civil contractors to overcome significant safety and workplace challenges. The project brought together two of Zinfra’s key business units, the Projects and Infrastructure Business Unit led by Site Manager, Dan Coleman, and the Power Services Unit led by Construction Manager, Gary Kiri.

PERSEVERANCE FROM THE BEGINNING

The first challenge of the project was early COVID-19 restrictions, which meant early planning and preparations had to be conducted remotely, without any physical visits to the site locations. Alongside these delays, La Niña wet weather systems continued to pose challenges to the Zinfra team on the ground. Although this impacted site visits associated with scoping and quoting, it didn’t impact the overall delivery of the work.

Undeterred by the obstacles, Mr Kiri said Zinfra and his team were resilient and persistent in getting on with the job.

“We adapt to the situation, we overcome it, and we keep moving forward. If there's a solution out there, we'll find it. That's the sort of people we are,” Mr Kiri said.

Supported by his team, Mr Kiri said each of his team members had a reliable and important skillset pivotal to solving the ongoing obstacles.

“The team that we have – they’ve been brilliant from the start. With all the challenges that we had, a lot of other crews would've just packed their bags and started walking down the road. But our team has been 100 per cent on board, and they have been coming up with solutions,” Mr Kiri said.

CONFIDENCE IN THE COMPLEX

With a focus on safety and teamwork in mind, the Zinfra teams were able to manage an increasingly complex construction site. Not only was Zinfra working in and alongside large concrete pits to install new cable conduits, they had to liaise with the civil contractors on site. This also involved managing large levels of construction equipment, such as large cranes, excavators, and trucks which often travelled across the main access road.

Zinfra’s trusted support and guidance was pivotal to the entire Molonglo transmission project. Mr Coleman said the

project required transparent and upfront communication between all parties to ensure that all work could continue in a safe and secure manner. This meant managing access roads, equipment and keeping sites as physically separated as possible. This experienced foresight reduced and removed site hazards and meant that the workforce was better protected against safety incidents.

“There was constant communication between us and the civil contractor to make sure that they knew where we were working on any particular day of the week, and that we had a reasonable separation of the two work fronts,” Mr Coleman said.

GETTING TECHNICAL

Part of Zinfra’s work, alongside undergrounding the transmission cable, was completing 17 joints, backfilling their pits, installing security fencing and infrastructure, then once all cabling was complete and tested, the decommissioning and demolition of 18 transmission towers.

The concrete pits the Zinfra team were installing new transmission cabling in were 1.3m deep, 14m long and 4.5m wide and were located alongside other contractors' work and equipment. The sheer size of the joint pits made organising site safety a major challenge.

“We had one instance where our jointers were at one of the pits and they were in full swing. It's a 12-day timeframe to do a cable joint, and they were working under their canopy,” Mr Coleman said.

“We recognised that there were going to be issues with work that needed to happen on the road adjacent to the pit. The contractor had to seal that road for the local government tourist facility owners, and that schedule overlapped with the joiners.”

Mr Coleman explained physical separation was necessary to avoid scrapers sliding down the hill into the pit. The hazard and solution were presented to asset owner Evoenergy, who trusted and followed Zinfra’s guidance.

Site safety also included several instances of innovation from Zinfra managers.

Mr Coleman explained getting access to the pits created a safety concern, wherein access needed to be secure and any pre-manufactured ladders wouldn’t suit the specifics of the pit. Organising their own purpose-made ladders ensured that the Zinfra team could access the pits safely, as well as being a more cost effective solution than purchasing premade options.

TRUST IN EXPERIENCE

Mr Kiri, with decades of experience in transmission work, said sharing his knowledge was pivotal to the success of the Molonglo project. Discussing safety concerns, not only with the civil contractors, but with the owner of the transmission assets Evoenergy, protected both the workforce, as well as equipment and the project timeline as well.

Mr Kiri’s knowledge and experience was also on hand from the beginning of the Molonglo project. Installing the cables that ran off large cable drums brought a significant problem when liaising with the other principal contractors. The civil contractor was planning on pulling the cable from a drum from the topside, but Mr Kiri knew that flipping the drum would be a better solution.

“I originally identified the cable pulling as a safety issue, because of the fact that we had two or three tonnes of cable at the end of the cable pool that would be still sitting up,” Mr Kiri said.

“We would have to somehow negotiate that cable off the drum and still be able to pull or keep pulling into the conduits.”

The benefit of Zinfra’s method, which also allowed drums to be set up staggered behind each other, saved the project extra financial fees as it shortened the time required to have a large crane onsite to lift the weighty cable drums.

“Our solution was more cost-effective. It was a lot safer to do, and we've got more control over the cable as it's going in,” Mr Kiri said.

“We can also identify any problems with the cable as it's going in, because it's at a lower level. So if there's a problem with the cable, we can identify it before it goes in and stop the cable pull and get the other civil contractor to take a look.”

THE FUTURE OF MOLONGLO VALLEY

The Zinfra team still has work ahead. The next step in the Molonglo relocation project will include testing on the complete circuit, and then beginning the dismantling of the decommissioned overhead lines.

“It's about 9.5km of conductor that we have to lower to the ground and then wind up and dispose of, and then decommissioning and the demolition of the ground towers,” Mr Coleman explained.

As Zinfra finishes work in the Molonglo Valley, a job well done means a job unseen. All 58km of cables will have been safely relocated underground, and 18 tower demolitions and removals ahead of area remediation will mark the Molonglo suburb ready for housing subdivisions. Thousands of future residents will benefit from the trusted work of Zinfra for years to come.

THAT POWERS ORIGIN'S GAS SUPPLY NETWORK

ORIGIN ENERGY PANEL OPERATOR SHAUN OATES WORKING WITHIN THE BRISBANE CENTRAL CONTROL ROOM

Origin Energy manages one of the largest gas supply networks in Australia, and controls and monitors thousands of gas assets as part of Australia Pacific LNG’s coal seam gas to liquefied natural gas project in Queensland. Here we take a look behind the scenes at the technology and operations used in the utility’s Brisbane Central Control Room (BCCR).

In a large, circular room, within Origin Energy’s Brisbane office, a team of operators sit amidst the glow of computer screens as they monitor dozens of panels displaying data from various sites and infrastructure across a vast integrated gas network.

This is the Brisbane Central Control Room – or BCCR – a 24/7 operation that monitors, optimises and operates the thousands of gas assets, including pipelines, processing plants, pipeline compression facilities and wells, to maintain production in a reliable and efficient way.

The assets are part of Australia Pacific LNG’s coal seam gas to liquefied natural gas project in Queensland, of which Origin Energy is the upstream operator.

COLLABORATION FOR SMOOTH OPERATION

BCCR Manager Nadia Vujovich said, “A collaborative team with a variety of skills is key to the BCCR's smooth operation.

“Within our team, we've got asset panel operators who run, optimise, and monitor our various assets around-the-clock.

“We also have automation and optimisation engineers who are responsible for making sure our assets and systems are always available and safe.

“There's even a lead engineer for automation and digital integration who sets standards and develops technologies to make sure the business network is using the best digital tools.

“These are just some of the various roles and responsibilities within the BCCR, and when combined, we can ensure a safe, reliable, and efficient operation of our integrated gas fields and facilities from a centralised location."

The BCCR divides assets into five panels, with panel operators focusing on their specific asset panel during their 12-hour shift.

In one corner of the room, an operator might be running the Condabri Panel, which would entail monitoring, controlling and optimising all assets in the Condabri Field. This consists of 565 operational wells, three gas processing plants, six compression trains, three high voltage substations, and 80 high voltage kiosks.

Nearby, another operator manages the Pipeline Panel and spends their shift looking after more than 980km of highpressure transmission pipeline across four interconnected

gas networks as well as pipeline compression facilities and gas processing facility metering skids.

“We manage about 3 million data ‘tags’, each of which represents a piece of data that is associated with an asset and contributes to the overall ability to operate our equipment remotely and safely. These assets can be as big as a compressor to a small piece of equipment like a temperature or pressure transmitter,” Ms Vujovich said.

“Additionally, there are about 250,000 alarms across the network with varying levels of criticality that may need to be responded to during a shift.

“At times, our capabilities can be stretched by the sheer volume of assets that we manage, but we pride ourselves on our ability to operate in a safe, calm and reliable manner.

“This requires a high level of competence and ongoing training to keep our team members upskilled and ready to respond to a range of scenarios.”

Despite the potential for high stress in the BCCR, there is a calm and quiet atmosphere, with only whispered conversations among operators, keyboard typing, and telephone or radio transmissions between operators in the office and various stakeholders or workers on site breaking the silence.

“During the shifts, our team communicates extensively with various site-based personnel,” Ms Vujovich said.

“We monitor production against our nominations for the day and maintain regular communication with other teams such as gas trading.

“We require team members to have a high level of focus and attention to detail, including participation in 12-hour overnight shifts. This makes managing fatigue risks and ensuring the wellbeing of staff, a crucial part of my role.

“It is an ongoing process to continually improve our understanding and management of fatigue, so we can keep our people safe and well.

"I really enjoy working in the BCCR and the daily challenges and opportunities that come with a 24/7 operational room.

“It is also a privilege to lead such a diverse team that comes from a wide range of backgrounds and experiences, united by a singular purpose – to operate our assets at a world-class level.”

HOW TO SAFELY AND EFFICIENTLY LOCATE UNDERGROUND UTILITIES

Accurate utility location is vital for many types of construction and development projects, as well as for routine maintenance and repair of utilities. Failure to locate and properly mark utilities can result in damage, costly repairs, service disruptions, and potential safety hazards. That’s why utilities and local governments are looking for solutions that can help them get the job done right.

Utility location can be a complex undertaking. Regulations and codes are ever changing, requiring the safest and most accurate methods for locating underground infrastructure.

Traditional excavation methods run the risk of damaging utilities, leading to outages and posing safety risks to workers and the public. It can also result in expensive repairs, project delays, and potential fines or legal action.

For utilities and local governments, it has become increasingly important to employ non-destructive digging (NDD) solutions.

SOFT TOOLS MEANS OPTIMAL PRECISION

As an NDD solution, vacuum excavators are safer than traditional excavation methods.

The vacuum excavator uses pressurised water or air to remove soil and debris from around buried utilities without damaging them. As the operator can control the suction power, it provides greater accuracy and precision.

Operators can choose what level of air or water pressure to use depending on the asset they are locating. Low pressure settings are better suited for gas and fibre lines, while the high-pressure function can be utilised for water pipes.

Local governments are under pressure to deliver projects quickly and at low cost. As a more efficient method for excavation, vacuum excavators reduce the time and labour required for utility location.

MINIMISING DISRUPTION

Communities also increasingly expect utilities and local governments to deliver works with as minimal impact as possible on the environment.

The vacuum excavator provides a more environmentally friendly alternative to traditional excavation as it leads to less surface disruption and reduces the risk of soil erosion.

For local governments, it’s important to limit noise that impacts communities while undertaking excavation works.

Vermeer has a range of vacuum excavators with integrated silencing systems for quieter operation. It works by dampening sound before it’s released into the atmosphere using an external engine compartment baffle system.

VERSATILE EQUIPMENT, WHATEVER THE PROJECT

As Australia’s network of utility assets continues to expand and more projects are delivered to communities, utilities and local governments are responsible for employing the optimal tools for locating underground infrastructure assets.

For a safe way to go about utility location, Vermeer has a wide range of vacuum excavators suitable for every job – big or small. With units ranging between 400L and 11,000L tank capacity and the CFM to match, there are numerous options to choose from.

Vermeer’s vacuum excavators are designed to save time, with features including telescopic boom 5” to 6” options, reverse flow and a smart in-take wash down system.

Vermeer’s vacuum excavators start at 5” and end at 10” by the time the spoil enters the spoil tank to save on blockages. Both the VSK100 and Deep Vac range have 5” booms, while the VX200-2000 model boasts the 6” boom.

To guide an efficient pathway for excavation, the Verifier G3 Utility Locator is durable, easy to use and does not require calibration. A three-year warranty offers coverage including water damage.

Vermeer’s vacuum excavators have an array of uses beyond utility location, including cleaning catch basins, digging post holes, sewer jetting and exercising water valves.

POC

VS POV: WHICH ONE DO I NEED?

Two crucial concepts that often emerge in conversations around scalable digital transformation are proof of concept (PoC) and proof of value (PoV). Here, we take a look at the differences between each term and what they mean for your digital transformation journey.

These terms may sound interchangeable, but they carry distinct implications, especially in critical operational environments where risk mitigation, technology integration and resource allocation all directly impact any changes to current operational processes.

PROOF OF CONCEPT (POC)

A PoC is a preliminary demonstration or experiment that aims to show the technical feasibility of a concept or idea. It's a controlled experiment designed to answer a fundamental question: "is this technology suitable for our needs?"

PoCs are typically carried out in a controlled environment, with the primary goal of answering questions like “can it be done?” Or "can we make this work?" PoC’s are also an opportunity to identify bottlenecks, assess technical risks, and validate whether the core idea has merit. PoC’s act as the litmus test, gauging the viability of a technical solution before allocating substantial resources.

PROOF OF VALUE (POV)

A PoV, on the other hand, goes a step further. It is no longer about technical feasibility, but about business impact. It aims to demonstrate the business value and benefits of a solution.

A PoV is designed to address questions like "does it provide tangible value to the organisation?" Or "does it solve the problem effectively and efficiently?" Here, the question importantly shifts from "can we make it work?" to "does it work for us?"

A PoV will usually involve implementing a solution in a real-world environment, with real data and user scenarios. An integral part of a PoV involves measuring the solution's impact on a relevant business KPI like operational efficiency, cost savings, staff safety, etc. It showcases the technologies’ true potential to deliver tangible value to the organisation.

DO I NEED A POC OR A POV?

A PoC is typically employed in the early stages of a project to demonstrate the feasibility of a specific idea or technology. It aims to validate whether a concept can be realised using the chosen technology or approach. A PoC often involves building a small-scale prototype or model that showcases the core functionalities of the solution. The focus of a PoC is on technical viability and feasibility.

You might need a PoC if:

• You want to test a new technology's compatibility with your existing systems

• You need to validate whether a certain approach can solve a specific problem

• You want to assess the usability and maintainability of the technologies

• You want to assess the technical challenges and limitations before committing to a full-scale implementation

On the other hand, PoV provides the empirical evidence required to convince stakeholders that an innovation isn't just the next shiny object, but a strategic investment in technology. It lays bare the concrete returns on investment and justifies the deployment of resources for wider implementation.

You might need a PoV if:

• You want to showcase the actual business benefits and outcomes of a technology or solution

• You need to secure buy-in from stakeholders by showing concrete results and ROI

• You're considering a larger-scale implementation and want to ensure the solution aligns with your organisation's goals

CREATING A POS

Combining both a PoC and proof of value PoV creates a powerful proof of solution (PoS).

When these two processes are combined, we have a comprehensive document that not only confirms the technology's feasibility but also demonstrates true potential by highlighting its measurable business value and benefits. A well-crafted PoS helps refine options early on, streamlining decision-making and mitigating risks, and provides the empirical evidence needed to secure stakeholder buy-in and justify resource allocation for broader implementation and a scalable rollout of technology. Ultimately, the successful creation of a PoS empowers organisations to confidently embrace and implement new digital solutions within their operational landscapes.

A solutions provider such as Madison Technologies can play a crucial role in delivering a PoC, PoV, or PoS by providing expertise, resources and guidance – and can greatly enhance your confidence in the solution's feasibility and value.

The transformative power of digital technologies discussion is happening in every boardroom and on every construction site in Australia. Yet despite well-established business cases, we’re lagging and slow in our uptake and use of the smart data that is essential for Australia’s future prosperity.

At stake is our economic productivity and net zero emissions targets, our talent pipeline and our international competitiveness. What’s up for grabs is greater productivity and better value for money, more sustainable and resilient infrastructure and better outcomes for people and communities.

Historically, the adoption of digital technology tools has been slow. This slow growth has been highlighted by several landmark studies over many years, most recently by Infrastructure Australia in its 2022 Infrastructure Market Capacity report, which notes that construction sector multifactor productivity has been stagnant for 30 years.

Collaborative leadership between government and industry is critical. Governments, as regulators, owners, funders and beneficiaries of public infrastructure, have a crucial role to play in driving the transition towards a ‘digital by default’ approach. This means moving away from the current ‘digital by exception’ mindset and embracing new technologies and digital practices from design through to procurement, construction, handover and maintenance to improve outcomes and boost productivity.

THE CHALLENGE

Australia has the potential to be a world leader in digital technologies and data tools in infrastructure and construction, but without holistic planning and implementation of cuttingedge technology, our efforts will continue to be disjointed. The challenges of a joined-up approach while considerable are not insurmountable.

THE URGENCY

In the 2019 financial year alone, the opportunity cost (i.e., the potential foregone construction output from a 30-year period of relatively weak productivity performance) was roughly $35 billion. Two years later, the opportunity cost had blown out to $47 billion. To put the size of this loss into context, the $47 billion figure for FY2021 alone dwarfs the cost of some of Australia’s largest current infrastructure projects (Australian Constructors Association, Disrupt or Die: Transforming Australia’s construction industry 2022).

THE DIVIDEND

A digital by default approach across infrastructure and construction will act as an enabler for policy priorities across government and deliver better value for money outcomes, supporting pathways to net zero, leverage infrastructure as a productivity lever, support better social outcomes and prepare for the future of work – and a future that’s made in Australia.

Are we ready for

DIGITAL BY DEFAULT?

By Frank Zeichner, CEO IoT Alliance Australia

A NET ZERO FUTURE

The application of digitalisation throughout the project lifecycle – from design through to construction, handover and maintenance is critical to reduce whole-of-life operations and measure, report and manage carbon emissions.

ClimateWorks Australia estimates that the construction and operation of physical infrastructure assets for transport, energy, water, waste and communications directly contributes to 15 per cent of Australia’s annual emissions. These assets also influence an additional 55 per cent of annual emissions through the activities they enable (Infrastructure Sustainability Council, ClimateWorks and Australian Sustainable Built Environment Council, Reshaping Infrastructure for a Net Zero Future 2020).

ARE WE READY YET?

National coordination is vital to accelerate social and economic progress, deliver transport and communication connectivity, support strategic regional development, enhance creativity and culture, and realise a competitive position alongside our global counterparts.

To support the transition to digital by default, Consult Australia backs the calls by other bodies, including IoT Alliance Australia and Infrastructure Australia, for the Australian government to play a leading role in being a

catalyst for infrastructure’s digital transition. Guided by the essentials below, the first step is to scale-up best practice and coordinate existing leadership. The Government can (and should) drive policy to build capability and procurement that supports innovation.

The essentials:

• A national approach to information frameworks and requirements applied across infrastructure assets

• Projects and programs recognising information as an asset that informs effective insights-driven action and investment throughout the project lifecycle

• All major contributors to infrastructure delivery have clear digital transformation strategies

• All infrastructure projects and programs to identify minimum critical data sets for design, construct and operate phases (and for carbon emissions tracking of infrastructure projects and adopt digital twins)

• Programs adopting development and procurement approaches that enable innovative infrastructure solutions and collaborative delivery models.

To kick this off, Consult Australia released the Digital by Default green paper as a trigger for nationwide collaboration. I encourage all stakeholders to join us as we take the lead in making Australia ready (and able).

MEETING MEASUREMENT DEMANDS

VEGA Australia, bolstered by its parent company’s global presence and innovations, is ensuring that the local construction industry has reliable, next-generation measurement technology to optimise assets and boost operational efficiency.

For more than 60 years, sensor and measuring instrument manufacturer VEGA has been developing the measurement solutions of the future, building upon a passion for innovation and transformation. In recent decades, the company’s local arm VEGA Australia has cemented partnerships with key players in the construction industry through its local supply of VEGA’s range of level, point level and pressure measurement instruments and technology.

PARTNERSHIPS DRIVING INNOVATION

Established in Brookfield in 1987 and now situated at its state-of-the-art site at Caringbah, New South Wales, VEGA Australia plays a key role in supporting the improved productivity and processes of the local construction industry, including the building materials sector.

VEGA Australia Managing Director, John Leadbetter, said that he has seen the company grow and develop in the local market throughout his 27 years with the business. He said the business’s success stems from the deep relationships and partnerships it has formed within the cement and concrete, quarry, brickworks, tunnelling and road construction sectors.

“We foster long term partnerships with the likes of Hanson, Holcim, Boral, Austral Bricks, James Hardie, CSR Gyprock and BHP Steel – many of which we’ve been working with for well over 20 years all around Australia.

“We are part of the international VEGA companies, and backed by that global experience, we’re able to deliver the highest quality, German-built level and pressure instrumentation locally in Australia.

“As the latest technologies come out that could help improve our customers’ operations, we introduce those technologies to them and help them upgrade to those latest technologies,” Mr Leadbetter said.

THE IMPORTANCE OF RELIABLE MEASUREMENT TECHNOLOGY

Providing innovative measurement technology that offers productivity, reliability and safety gains is the cornerstone of VEGA Australia’s offering. At a time when a wealth of challenges continue to torment the construction industry, it has never been so important for the sector to harness solutions to move the needle on productivity and efficiency. According to the Australian Constructors Association’s report Disrupt or die – Transforming Australia’s construction industry, 2020, improvements to the construction industry’s productivity performance could save Australia $47 billion annually.

Mr Leadbetter said that reliable measurement data can play a huge role in shifting these statistics, “In days gone by, level and pressure measurement tasks would be completed by a person that would physically have to go out and check the bins, dip tanks or silos and enter measurement records on spreadsheets about what material they had on a plant,

“This resulted in extra work, safety risks from having that person around the equipment, which may contain hazardous materials, and poor reliability due to the probability of human error.

“Our instruments, on the other hand, provide a continuous, accurate output about the amount of level in a silo, saving time, improving efficiency and enabling maintainers to focus on other tasks.

“Our sensors can tell you where the sumps are and anything to do with information about what’s happening in the plant itself,” Mr Leadbetter said.

LEADING THE WAY WITH AUTOMATION

As the construction industry enters an age of automation and information, VEGA Australia is delivering automated units that are developed to withstand and suit tough, dusty, noisy and mechanical industry environments.

Mr Leadbetter said that customers are looking for reliable and accurate information.

“They’re looking for automated solutions that they can integrate into their plant so that they require less manpower and more mechanical type power,” Mr Leadbetter said.

“That’s where VEGA Australia comes into it. We don’t just offer goods for sale – we go out and there and offer the sensor solution to the customer and assist them in identifying the best location for it, how to install it and most importantly, setting the instrument up.

“By offering this comprehensive support and service, as well as our quality, technology-driven instruments, we provide the customer with confidence that they have reliable equipment that’s dependable and that they will get years of service out of.”

REDUCING WASTE

The construction industry is also a huge generator of waste. During the 2020–21 financial year, building and demolition materials were responsible for approximately 25.2 million tonnes of Australia’s generated waste – according to the National Waste Report 2022 prepared for the Department of Climate Change, Energy, the Environment and Water by Blue Environment.

Further to the environmental impacts associated with waste generation, it also costs businesses money and Mr Leadbetter said that having an accurate, repeatable system, like VEGA Australia’s sensor technology, can greatly reduce waste.

“For instance, the VEGAPULS level measurement radar can accurately track a tank’s capacity to protect against overflow, with no contact required by personnel.

“Addressing the current skills shortage, VEGA Australia’s measurement instruments do the job of what previously would have required personnel to complete, resulting in a better use of resources.

“Also, our sensors run on 24V direct current. They are low power devices that don’t require alternating current power or high power to run them,” Mr Leadbetter said.

REDUCING WORKLOAD

VEGA Australia’s measurement solutions also boast reliable and optimal performance 24 hours a day and all measurement units are self-assessing – they alert the maintainers to problems so that they can head out there and fix the problem or replace the damaged unit if required – meaning supervisors and managers don’t have to worry about things going wrong.

As the building materials sector continues to improve and develop its infrastructure, larger sites with several different pieces of equipment are required to achieve the higher throughput. Many sites are now being fully automated, helping the production of materials for the construction industry to be delivered on time. Construction companies used to have delays purely due to the fact that the materials that were required for their projects were taking longer to get there, Mr Leadbetter said.

“If the materials are getting there on time, the construction companies are able to plan further ahead, reducing or eliminating the effect of delays.

“With our sensors doing the heavy lifting in the level and pressure measurement space, we’re supporting building materials companies in getting materials out to contractors at a quicker pace.”

Primarily delivering sensors for level and pressure measurement, VEGA Australia tailors its solutions to fit what the customer is looking for.

The company is at the forefront of radar level and guided radar developments, two product ranges that are continuously used in the construction and building materials sector, and also offers pressure transmitters and switches. “All of our products are developed for the market, not the price point,” says Leadbetter. “We’re not all about the latest technology being the highest price.”

Many of VEGA Australia’s solutions will be on display at the 2023 Inside Construction Expo on 20-21 September. The company will be showcasing working models that aren’t just planted on a desk – they’ll be powered up and working.

“Attendees that visit our stand (D20) will get to speak to people who are dealing with their industry daily, and have industry knowledge and established industry relationships,” Mr Leadbetter said.

“They’ll get to meet our team and see the equipment in action and most importantly, see that we’re at the event to help drive the construction industry forward.”

“We aim to play our part in helping develop and futureproof the industry, foster new and existing relationships, and hopefully show attendees something that they’ve never seen before.”

VEGA Australia, with the support and experience of the global group of VEGA companies, endeavours to be at the forefront of level and pressure measuring solutions for the local construction and building materials markets. Be sure to visit the company’s stand at Inside Construction Expo 2023 to discover the latest and emerging developments in sensor technology.

MECHANICALLY SEALING PIPE PENETRATIONS AT AN AUSTRALIAN CHIP FACTORY

ATo ensure that piping equipment remains functional and leak-free, selecting the right seal model to suit the nature of the substances it comes into contact with is of the utmost importance. Here we take a look at a recent case study and discuss the considerations that need to be made when choosing a seal.

n Australian potato chip factory built five brand new concrete tanks to collect wastewater that contained a low concentration of cooking oil at. The client required an instant permanent solution to seal six core-holed pipe penetrations to accommodate new HDPE pipework passing through the tank walls. The tanks and penetrations are now buried underground, so it was of the utmost importance that the tank remain leak free and sealed using the appropriate materials to provide a reliable long-term seal solution in these harsh conditions.

Projex Group offers professional advice and calculations in selecting the right Link-Seal sizing and model to best suit the substances in contact with the seals. The Link-Seal model “O” was selected for the project, as it is resistant to oils and suitable for highly corrosive environments.

There are numerous benefits in using Link-Seals for these applications. LinkSeals have no downtime on curing and unlike other products they do not shrink during the curing process. Link-Seals are maintenance-free after application, but if a leak occurs due to excessive pipe movement then Link-Seals can be tightened and adjusted.

Link-Seals have been widely used across Australia for more than 15 years. They are best suited to applications where the sealing of penetrations is critical and of the highest importance, such as gas plants, oil refineries, hospitals,and water and waste treatment plants. Link-Seals are available in liquid, gas, oil, temperature and fire-resistant models and can seal pipe penetrations ranging in diameter from 10mm to 3.6m.

Link-Seals offer hundreds of solutions to seal pipe penetrations ranging in size from 10mm to 3.6 metres diameter.

Link-Seals are suitable for most types of pipes including PVC, HDPE, Copper and Steel.

Resistant to water, oil, gas, aggressive chemicals and fire.

Projex Group helps calculate the right Link-Seal size and model for your application.

BREAKING NEW GROUND IN REDUCING UTILITY RISK

If not located correctly, underground utilities are at risk of being damaged during the installation or construction of new assets, which can have devastating consequences. A New Zealand-based utility locating company has uncovered a solution using the digital visualisation technology.

When construction or new asset installation impacts underground utilities such as gas, water or power mains, the consequences can be expensive, and even deadly.

According to Reveal, utility strikes cost New Zealand $89 million annually in direct costs and $2.5 billion per year in indirect costs – a staggering 1.17 per cent of GDP.

Reveal CEO and Founder, Sam Wiffen, said Reveal provides a solution to what has been a long-standing issue across the construction and infrastructure sectors.

“I have an engineering background and used to work on large upgrades of buildings and electrical substations across the civil construction and heavy electrical sectors. We kept on hitting objects underground, primarily because we didn’t have accurate information and records on what was underground,” Mr Wiffen said.

Reveal started as a traditional ‘boots on the ground’ utility locating services business, but Mr Wiffen was eager to build a foundation of technology and innovation in an industry notorious for being slow to modernise.

“Locating underground utilities is really hard. Our thinking was, ‘How do we make that job easier?’ When you think about Superman, having x-ray vision, that would be amazing. But what if everyone was Superman or Superwoman?”

Existing geophysical tools can provide insights into the hidden environment of the subsurface and indicate the presence or absence of underground utilities. But historically, this information has been difficult to visualise or make accessible to non-specialists.

“If we could ensure that contractors and project owners could accurately and easily implement subsurface data, we could reap huge efficiency gains at every stage of the project lifecycle, from the concept and design phase through to construction,” Mr Wiffen said.

A DIGITAL UNDERSTANDING OF THE UNDERGROUND

The Reveal platform combines the best-practice utility locating standards in an intuitive cloud-based collection of tools that allow engineers, contractors and asset managers to understand the risks of a given project site, and make informed decisions.

The platform collates all existing information about the underground; utility plans, geophysical detection data, observation and aerial data, and photographic evidence from 360-degree cameras, Lidar and photogrammetry tools.

The platform allows users to create a Unified Utility Model that synthesises all these data sources and produces the most accurate picture of the subsurface infrastructure, with associated risk scores and quality levels clearly indicated.

“We’re helping people to not just take the existing records of utilities and combine those before making a design, we’re providing an understanding through a subsurface utility engineering process to identify where these risks lie,” Mr Wiffen said.

NAVIGATING UTILITY STANDARDS WITH ADVANCED ASSET MANAGEMENT

At the heart of the utility industry lies critical assets – the indispensable infrastructure encompassing power plants, pipelines and water treatment facilities that deliver essential services to communities. Compliance, therefore, stands as the safeguard ensuring the integrity, reliability and safety of these vital services. Failure to comply can result in service interruptions, loss of trust between organisation and customer, and costly audits and repairs.

However, in an ever-evolving utility landscape, meeting the complex web of industry, domestic and international standards can prove challenging. This is where strategic asset management comes into play, ensuring utilities not only meet but exceed mandated standards.

GUIDING UTILITY EXCELLENCE

Tailored asset management systems, like the ISO 55000 standard, provide utilities with comprehensive guidelines, ensuring assets are not only operated efficiently but also compliant with industry regulations. This approach involves exhaustive steps, from taking asset inventories to continuous improvement strategies, all essential components of a robust asset management system.

Another key international standard for organisations looking to ensure efficient management is ISO 9001 – a system based around ensuring quality management systems. With core values and priorities of supporting effective business management, fostering operational resilience, ensuring long-term success and customer satisfaction, it’s clear why this system is so pivotal to those organisations with a service guarantee.

STANDARDS IN ACTION

Fusion welding is a core process that is used across utilities, often in relation to pipeline construction, that involves melting materials together. This process is heavily regulated, not only with the work itself, but the recording of weld data. This is incredibly important because weld data must be kept for auditing purposes, as well as for maintenance of the asset. Welds, as part of major

infrastructure, can cause devastating effects if they fail, and the recording of data is seen throughout weld guidelines.

Within utilities, welding standards, such as the POP003 guideline, play a pivotal role. Fusion welding demands meticulous adherence to data recording protocols outlined in standards like ISO 21307 and ASTM F2620. The Plastics Welding Service Provider (PWSP) must establish quality management systems, ensuring installation, welding and jointing work align with ISO 9001 specifications, as per the WS2 – Thermoplastics guidelines.

DIGITAL ASSET MANAGEMENT

Strong asset management relies on data collection and analysis to make informed decisions. However, the amount of data required can be difficult to maintain and record successfully if proper asset management systems aren’t in place. Fortunately, digital solutions are making it easier than ever to record data, ensure it is accurate and accessible, and mitigate the risk of human errors – a common concern in traditional paper-based systems.

PE Weld Bank is one such solution, it enables seamless recording and monitoring of pipeline and weld assets and is compatible with all hydraulic Butt Welders.

TALKING FATE AND TRANSPORT OF MICROPLASTICS WITH SOUTH EAST WATER

Growing global concern about microplastics has spurred a range of research and studies into the different methods that can be adopted to reduce their widespread presence. Recent studies undertaken by South East Water can help water utilities gain invaluable first experiences in sampling and characterising this contaminant.

Concurrent with the increase in production and usage of plastic materials worldwide has been the prevalence of microplastics (MPs); minuscule bits of plastic debris caused by the disposal and subsequent disintegration of consumer products and industrial waste.

These MPs can pose a danger to the environment and public health, and have been found in the air, tap and bottled water, sea salt and even in fish caught for human consumption.

The composition of microplastics can create significant health risks, as it can accumulate in the food chain and impact human food. As well as this, other toxic substances and undesirable chemicals can attach to the miniscule particles, and human ingestion can lead to increased exposure to these chemicals and result in harmful health problems.

Sewage is a point source of MPs in the environment, with water recycling plants (WRPs) serving as a pathway for this contaminant to enter the environment. Despite this, existing WRPs across Australia are not specifically designed to manage MPs pollution.

The effective management of the MPs risks requires a detailed understanding of the fate and transport of MPs in existing sewage treatment systems.

In addition to this, Australian water utilities generally have limited or no experience in sampling and analysing MPs.

There has also been a lack of knowledge about the efficiency of lagoon-based WRPs in removing MPs, a significant gap considering 60 per cent of more than 1,200 WRPs across Australia using ponds/lagoons as the primary treatment step, and 77 per cent using ponds as one of the treatment steps.

In an attempt to better understand – and even potentially mitigate in the future – the prevalence of microplastics in Australian water utilities, South East Water partnered with the RMIT University team led by Associate Professor Linhua Fan to carry out the first long-term MPs study at WRPs in Australia.

Conducted over two years, the study covered the fate and transport of MPs in three of the company’s WRPs, examining different treatment scenarios used by the Australian water industry.

THE STUDY

In carrying out this study, South East Water strove to cover all the different treatment scenarios used in Australia’s water industry, selecting three of the most representative WRPs at South East Water that include the most traditional activated sludge treatment process, the most advanced membrane treatment process, and the simplest lagoon-based process.

The study covered industry catchment and residential catchment, as well as large-scale treatment plants and small-scale treatment plants.

When it came to conducting research on these microplastics in WRPs, South East Water’s Strategic Research Manager, Dr Li Gao, said there were a lot of challenges.

“At the beginning, we didn't even know how to sample, or how to characterise and analyse microplastics, as no standards were available. This study was the first time a water utility had tried to do this. We needed to learn how to take samples of microplastics from sewage, how to analyse them, and how to characterise them.

“This characterisation wasn’t easy. Sometimes, it can be hard to differentiate microplastics from other materials present in the wastewater samples. You have to use advanced analytic methods to actually differentiate them.”

Dr Gao said the study allowed water utilities to gain industry-first experiences in sampling and characterising MPs.

The study identified that the different treatment systems under the study can all achieve promising removal of MPs (more than 97 per cent). Furthermore, a seasonal variation of MPs concentration was also found, which was determined to likely relate to stormwater events in the catchment.

“The results highlighted the potential of low-cost/lowenergy lagoon-based WRPs for microplastics control,” Dr Gao said.

“Our findings help to address key knowledge gaps while also helping water utilities successfully manage microplastics in WRPs, mitigate microplastic pollution risks in the environment, and address community concerns.”

MOVING TOWARDS A CIRCULAR ECONOMY

As well as providing industry insight and knowledge this research is making progress towards helping South East Water move towards a circular economy-based business model.

“Recycled water is a very, very important component for the circular economy. Water is a precious resource, and we need to make use of as many alternative water sources as possible to ensure we protect our drinking water so it can be used where it's needed most.

“To enable recycled water use, we have to make sure it complies with all the guidelines, and make sure it doesn't pose any environmental or public health risks.”

Dr Gao said that with MPs as an emerging contaminant, it is important to get a better understanding of them, their impact and their removal.

“We have to remove them, and we have to provide the best quality of recycled water. This research helps South East Water and the water industry at large achieve better outcomes and supports a circular economy.”

The research outcomes have so far resulted in two articles published in high impact peer-reviewed international journals. South East Water has already adopted the research outcomes for the risk management of emerging contaminants and strategic planning for the company's future water recycling facilities.

The South East Water and RMIT research has already had significant economic, environmental and social impacts, with the findings likely to reframe how the Australian water industry will meet the challenges of emerging contaminants.

THE FIVE STEPS TO BUILD A RESILIENT WATER MANAGEMENT SYSTEM

While there are various environmental, financial and social factors that utilities need to take into consideration to develop a resilient water management system, these are the five must-haves for a utility to be successful.

All utilities are facing similar challenges around climate change. This requires the implementation of net zero targets and new, innovative ways to repair environmental damage, as well as the development of technology that protects communities from future dangers.

SUEZ, a leading water and wastewater management solutions company, has recently released its strategic plan for 2027, which focuses on these challenges as well as the innovations in water and wastewater management that can help solve them. The strategy discusses how local innovation, new technology, community engagement, and new procurement opportunities can increase water efficiency, accuracy and savings for customers.

Drawing from SUEZ’s partnerships with various Australian utilities, Utility Magazine has created a list of the five steps utilities need to take in order to create the most resilient, reliable water supply system for customers.

1. INVEST IN RESEARCH AND DEVELOPMENT

Research and development (R&D) can provide economic growth, solutions to future challenges, higher operational efficiency, and is more likely to ensure long-term customer satisfaction for utilities. It is also critical for utilities that are undergoing major upheaval to meet new government renewable targets.

Utilities need to partner with delivery partners who can invest in the research and development of innovative designs and technologies to minimise the impacts of extreme weather events like flooding and droughts.

SUEZ’s new strategic plan includes a 50 per cent increase in the company's research and development budget, with the goal of creating circular solutions for water and waste sectors by 2027. Goals like this will enable the company to improve the quality of end-users’ experiences by investing in the

development of technology that preserves water by detecting leaks in networks and offering new data on user consumption.

By investing in R&D, utilities can ensure the complete, long-term success of their assets, as well as future-proof against subsequent technology shifts.

2. PRIORITISE PROCUREMENT

Once utilities have researched the innovations needed for optimal water asset management, they must then turn these ideas into reliable products and services. Utilities need to procure and deliver the digital, social and sustainable resources that will best serve the particular needs of its customers and stakeholders.

SUEZ’s General Manager of Innovation and Performance, Eric Garcin, said, “Given the droughts and flooding that Australia is facing, the needs of the community are always evolving. Procuring advanced innovative solutions that are well integrated in the overall system ensures that the local environment isn’t going to negatively impact customers in the future and vice versa.

“There’s plenty of other benefits, too. Procuring new designs and resources can lead to more growth and customer satisfaction in the long haul. It helps customers understand where their money is going, and how they can save on unnecessary costs with more advanced and durable solutions. By prioritising procurement, you’re not just designing a new future – you’re cementing a trust between your business and the communities you serve.”

3. EMBRACE THE INTERNET OF THINGS

SUEZ’s procurement strategies within its Australian contracts have often involved IoT-connected devices, such as smart meters. Internet of Things (IoT)-connected water management systems have the intrinsic advantage of data analysis.

Sean Cohen, Head of Smart Metering at SUEZ, said, “When implemented correctly, IoT devices offer accurate, reliable, and real-time data of customers’ water networks. You won’t be put on a waiting list to have your water systems checked for leaks – IoT tech like smart meters can detect any faults immediately.”

Smart meters provide utilities with almost instantaneous data insights into network usage. These insights will allow SUEZ to predict faults, quickly repair leaks, provide accurate water bills, and reduce local environmental impacts.

4. LEVERAGE DATA FOR CUSTOMER-CENTRIC COMMUNICATION

New innovations – like IoT-devices and smart meters –assist with long-term water management challenges, such as water leaks, which increase customer bills and general dissatisfaction. By monitoring water consumption in new ways, utilities can better prioritise customer needs and provide useful insights to their local communities.

Customer-centric water management strategies allow customers to understand where their money goes, where their water is coming from, and how faults or repairs may affect their daily usage.

“Providing end-user information is a critical step towards building a resilient water management system. We’re making sure that communities aren’t paying for something that never even reaches them. Providing this data is creating a new level of trust and accountability for our customers,” Mr Cohen said.

“We never want to cost local taxpayers excess amounts for water that may get lost in faults or leaks. With digital technologies, we can not only keep customers informed, but we can also work with them to repair leaks and pre-empt these kinds of future problems. We can interact with our customers – and solve their needs – in near real-time, with improved accuracy.”

By understanding the unique needs of your customers, utilities can install a digital water system that ensures the most secure, inexpensive and future-proof services.

5. ADOPT A HOLISTIC APPROACH TO SUSTAINABILITY

The last step utilities must take is inherently tied to sustainably managing their assets. This encompasses more than just a ‘green’ approach; rather, requires looking at sustainable asset management through a holistic lens.

Utilities around the world are facing an increasing number of challenges related to the management of their water assets. From climate change and population growth to changing regulatory requirements and stakeholder demands, they must find ways to manage their resources sustainably and responsibly.

One approach that can help meet these challenges is adopting an ESG sustainability approach. ESG stands for environmental, social, and governance, and this approach involves considering a wide range of factors that impact the sustainability of their organisation.

In the context of utilities, an ESG sustainability approach involves considering a range of factors related to managing their water assets. This includes environmental factors such as water quality, the impact of climate change on water resources, and the ecological impact of water management practices. It also includes social factors such as stakeholder engagement, social procurement and the impact of water management on municipal, peri-urban and regional communities. Finally, it encompasses governance factors such as regulatory compliance, risk management, and the effectiveness of internal controls.

As part of SUEZ’s sustainability roadmap, the company has adopted a three-pronged approach to tackling these issues:

• Climate: Contributing to decarbonising energy, reducing greenhouse gas emissions and adapting its most exposed sites to climate change.

• Nature: Preserving biodiversity and natural resources wherever we operate.

• Social: Strengthening the positive impact of our activities to ensure the responsible development of communities.

“SUEZ’s approach to sustainability will help utilities identify risks and opportunities when managing their water assets. For example, by considering the impact of climate change on water resources, we can help utilities develop strategies to manage water scarcity and protect against drought,” said Mr. Garcin.

“By engaging with local communities and stakeholders, utilities can better understand the social impact of their activities and identify ways to enhance social value. And by ensuring regulatory compliance and effective risk management, water authorities can improve their governance and maintain the trust of stakeholders.”

“Ultimately, this can help ensure the long-term availability and quality of water resources and enhance the value of water management to all stakeholders.”

ENSURING RESILIENCE FOR FUTURE GENERATIONS

By considering and implementing these five steps, utilities can build a resilient and sustainable water management system for their communities. Investing in R&D, prioritising procurement, using digital technologies and adopting a multi-tiered approach to sustainability can safeguard assets against environmental, economic and social challenges that may arise.

“Ultimately, we want to ensure utilities can have long-term availability and quality of water resources so they can provide manage their assets in the smartest, most sustainable way,” Mr Garcin said.

“It is a complex and ongoing process that requires cooperation and collaboration between government, industry, and communities. By investing in water asset management, we can ensure utilities that we provide a reliable and resilient water supply for their communities – now and into the future.”

FOR THE NEXT GENERATION TRANSFORMING ASSETS

The Wharf Street Basin Next Generation Community Park is a key project for the Canning City Centre Regeneration Program, which is a ten-year, $76 million program that aims to transform Canning’s City Centre into Perth’s southern CBD.

Wharf Street Basin has been reimagined as a new smart park and is one of the City of Canning’s centrepieces of urban renewal.

Located at 109 Wharf Street, Cannington, Western Australia, walking distance to Cannington Leisureplex and Westfield Carousel, the Wharf Street Basin Next Generation Community Park is a pilot project for water sensitive infrastructure and technology. It was an inaccessible stormwater basin, fenced off from the public for 60 years, which has now been transformed into a community smart park and a jewel in the crown of the urban regeneration of Canning City Centre.

The Next Generation Park is a one of a kind where nature and technology meet to give the community a place to relax, connect with nature and learn more about water.

This innovative park has solved practical problems and created a project framework that will serve to be a model for all of Western Australia and even more widely across Australia.

The City of Canning has collaborated with Western Australia’s thought leaders and key government agencies in urban redevelopment and landscape architecture to use landscape design and technology solutions to create a recreational space that incorporates a new approach to stormwater management.

The City worked closely with the Water Corporation’s Drainage for Liveability program to take down the fence from around the stormwater retention basin, while ensuring that the site remained safe for the public to access, and also maintained the basin’s core flood management function. Where once the site was inaccessible, with low biodiversity and no amenity, it is now a thriving oasis within the urban landscape. The local community now have a place to relax, watch the wildlife that is calling the site home, and admire the beautiful native plants that have been incorporated into the landscaping. There is also room to exercise, as well as meet up with friends for a picnic lunch.

The park has some unique features that set it apart from other parks:

• An augmented reality (AR) app, Smart Canning, lets you be a scientist, play games and learn about stormwater – all while using your mobile device.

• A 40m large mural painted on the Wharf Street side of the park. Designed and painted by two Perth artists, Brenton See and Jade Dolman, the mural is a celebration of water, the site’s plants and wildlife and the Whadjuk Noongar people's connection to water and the landscape.

• A small nature play area located near the mural (southern end of the park). It has a water play feature, log steppers, a balance beam, log stilts and is suitable for young children.

• An open-air pavilion, which can be used as an outdoor classroom for school groups.

Other facilities include universally accessible pathways, bike racks on site to lock up your bike, seating to stop, rest and enjoy the views across the water, a boardwalk, and a bridge to easily connect between Leila Street and Cecil Avenue, lighting that allows for safe evening use of the park, Wi-Fi within the park, several smart charging benches to plug in your USB cable and drinking fountains and a water bottle refill station.

The project was co-funded by the Federal Government who contributed more than $1 million as part of Smart Cities and Suburbs funding back in 2018.

The City also partnered with Water Corporation’s Drainage for Liveability, Department of Water and Environmental Regulation, Department of Biodiversity, Conservation and Attractions, Urbaqua, Curtin University and Innovation Central Perth and contracted Josh Byrnes and Associates to design the project and Environmental Industries to deliver the park.

COMBATING WATER SCARCITY WITH DIGITAL WATER METERING

With the arrival of El Niño comes pressing concerns for water security and inevitable water restrictions as utilities are faced with the challenge of limited water supply. Equipping consumers with water consumption data allows them to keep a close eye on their water usage, and reduce water waste at a time when every drop counts.

As we approach the hot and dry summer months, water scarcity is an increasingly pressing concern for many communities and water providers. While water restrictions have traditionally been a primary means of reducing water demand during these challenging times, the lack of real-time water consumption data often leaves the public unaware of their usage patterns and potential wastage. Taggle Systems Digital Water Metering (DWM) empowers consumers to monitor their water consumption effectively and identify and rectify water leaks promptly.

EXTENDING THE TIME BEFORE RESTRICTIONS

DWM has the potential to extend the period before water restrictions become a necessity. By providing consumers with real-time data on their water usage, individuals can become more aware of their consumption habits and make conscious efforts to reduce wastage. For example a resident with a leaking toilet might not think much of the leak, but when the data shows the leak is 10–15L per hour, which equates to 240–360L per day, they will likely take quicker action to fix it.

Taggle’s meter data management software, Aqualus Water, includes a Customer Portal in which end users can set up leak and high consumption alerts as well as weekly and monthly reports. For those not signed up to the customer portal, utilities can send leak notices via email, sms and by letter to properties with leaks. When restrictions are on the cards these tools can significantly reduce the amount of unnecessary water loss and overall demand on water resources, delaying the need for stringent restrictions.

EDUCATING THE PUBLIC IN A POSITIVE WAY

One of the advantages of DWM is its capacity to educate the public about water conservation in a positive and engaging manner. Traditional water restrictions often lead to frustration and resentment among communities and some who abide by the rules of outdoor watering are in fact using a lot of water. When individuals can see their water consumption patterns displayed on a user-friendly interface, they are more likely to take ownership of their

usage and willingly reduce it. High water consumption activities like watering the garden can be clearly identified and quantified with hourly data. This approach fosters a sense of responsibility and encourages voluntary water conservation efforts.

PREVENTING WATER THEFT

Water theft increases during water restrictions with thieves putting additional strain on already limited resources. DWM makes water theft much harder to conduct. The meters are equipped with tamper alerts and provide hourly readings, making it challenging for individuals to manipulate their water consumption. The data itself can also highlight unusual usage that can be investigated.

Commercial properties are often targets for thieves, DWM data has identified cases where drum loads of water have been stolen regularly without the property owner even knowing. With the Customer Portal, these activities can be identified and action can be taken. Without the consumption data the property owner would have been none the wiser and paying for the water consumed.

TOOLS FOR UTILITIES

DWM also offers invaluable tools for utilities and water providers. Aside from leak notices, utilities can identify properties with consistently high water consumption and engage with homeowners and businesses to pinpoint highuse activities and wastage.

Similarly, with whole of network water consumption data, utilities can direct messaging and water saving strategies depending to areas with excessive water use or where resources are scarce. This consumption data can be analysed against supply meters to calculate network losses through District Metering Areas (DMA).

Aqualus Water also provides utilities with many visualisation tools and reports to help manage the water network as efficiently as possible.

Stringent water restrictions impact local businesses and the community. By extending the time before water restrictions become necessary, we can improve quality of life and reduce water stress. As we face increasingly severe water scarcity challenges, DWM emerges as an essential tool in our efforts to preserve this precious resource now and into the future.

THE DOUBLE-EDGED SWORD

OF SENSOR TECHNOLOGIES IN LEAKAGE MANAGEMENT

The pursuit of reducing nonrevenue water has rendered sensor technologies irresistibly appealing to utility companies. These innovative devices boast transformative leak detection capabilities but simultaneously introduce a suite of operational and regulatory quandaries requiring thoughtful navigation.

The initial allure of sensor solutions is their ability to monitor leaks across an entire pipeline network. However, this advantage can mislead utilities into underestimating long-term implications. It's vital to thoroughly examine the financial landscape, as hidden costs often emerge beyond initial purchase and installation.

A key concern with extensive sensorisation is the rise in false positives. In a recent case, a utility relied on new AI sensor technology to identify what seemed to be a water leak. Upon further inspection, it turned out to be electrical interference – correctly identified by older equipment and experienced technicians. In this instance, actual intelligence trumped artificial intelligence.

Such erroneous alerts bloat operational costs and misallocate vital focus and scarce resources away from genuine problematic areas of the network. Consequently, while low-cost sensor technologies may come across as a budget-friendly venture at first glance, the total cost of ownership can be substantially higher. This includes hidden costs, ranging from the resources squandered on investigating these fallacious alerts to the operational adjustments necessary for integrating new technologies.

The vigilant oversight from regulatory bodies introduces another layer to the operational complexities. When a surge

of alerts originates from the newly deployed sensors, these agencies naturally ratchet up their expectations for prompt and effective remediation. Non-compliance with these recently elevated standards exposes utilities to financial repercussions and can harm public trust and credibility. This amplified scrutiny only complicates the adoption process, underscoring the need for a more strategic approach.

Given these multi-faceted challenges, utilities must proceed with caution and strategic planning when embracing widespread sensorisation. A rushed or fragmented introduction of these technologies is counterproductive at best and disastrous at worst. Utilities would benefit from crafting a robust, comprehensive strategy for seamlessly integrating these tools into their existing operational frameworks – one that harmonises with internal performance objectives and external regulatory benchmarks.

To conclude, as the water sector boldly strides into an era of sweeping modernisation, it's paramount to meticulously weigh the prospective technological advantages against the inherent operational and regulatory impediments. By adopting a balanced, well-rounded approach that accommodates these multiple dimensions, utility companies stand a more substantial chance of attaining long-term, sustainable triumph in reducing non-revenue water.

THE HOT TOPIC

OF WATER SECURITY

As we face a future affected by climate change, the reliability of our water systems becomes more important than ever. But when water security covers such broad ground, where do water authorities focus?

Interflow’s Contracts Manager, John Weaver, said that at the centre of most water security success, is a wellmaintained asset base.

“In the late 1970’s and early 1980’s there was a flurry of new sewer and water construction throughout Australia. In the late 80’s and early 90’s, the sector moved away from new construction and towards asset management.”

Legislation was introduced that required councils and water authorities come up with long-term plans to maintain the value of their assets.

“That led to a lot of the relining work that Interflow did from the early 1990’s, which is how we became deeply involved in water security,” Mr Weaver said.

While maintenance will always be a core focus, the attention of water managers is also shifting towards ensuring water supply will not be affected by climate change.

“In other words, how do we take the stuff that falls from the sky, hold on to it and reuse it over and over again. That’s the next phase of water security.”

Mr Weaver believes that recycling will play a major role in the water security solution in Australia. This has to do with reusing wastewater in the potable supply, as well as considering where wastewater is being sent.

“Right now there is a great deal of discussion around treated water being reinjected into aquifers for storage, and then being reused, for example,” Mr Weaver said.

“Western Australia has led the charge in this space, and replenishing groundwater with purified recycled water is now common practice in Perth.”

HOW DO WATER MANAGERS PREVENT WATER LOSS?

Non-revenue water loss is a very big issue in Australia and globally. In Australia, according to the Bureau of Meteorology, non-revenue water loss stands at around ten per cent of water utilities’ system input.

“Of course, the more that networks reduce water loss, the less water we will require in the long run,” Mr Weaver said.

“And so, a large part of the solution lies in the network. How can the water network be optimised and operated with a program that identifies potential leaks before they actually occur?

“That solution involves a mix of data-driven technology and proactive renewals programs.”

HOW CAN INTERFLOW HELP WITH WATER SECURITY?

Interflow’s role in water security right now is in collaborating with water authorities on their water and sewer renewals targets.

The organisation’s goal is to continue to improve the reliability and service life of water assets, meaning water authorities should be seeing less bursts and leaks, and instead conducting more proactive maintenance and renewal.

“A big part of the solution comes from innovation and better ways of doing things, which is what Interflow does best,” Mr Weaver said.

“When we’re part of the conversation from the beginning, we can often help release funds and resources into other areas, so water authorities can continue to improve.”

We’re Creating the Future of Water through secure and reliable water systems

FOR GLADSTONE IN THE PIPELINE LONG-TERM WATER SECURITY

In February 2023, the Queensland Government approved the Fitzroy to Gladstone Pipeline (FGP) for construction. The FGP is a $983 million pipeline to address the single source water supply risk from Awoonga Dam, enabling long-term water security to Gladstone’s industry and support ongoing economic development in the region.

The 117km pipeline will run from the Lower Fitzroy River in Rockhampton and connect to Gladstone Area Water Board’s existing water network at Yarwun. The pipeline comprises a water treatment plant, reservoirs and pumping stations at locations along its alignment including Laurel Bank, Alton Downs and Aldoga.

The FGP will have the capacity to transport 30GL per annum from the Fitzroy River to Gladstone, and is designed to be efficiently retrofitted with additional infrastructure to enable bi-directional flow in the future.

McConnell Dowell BMD Group Joint Venture (MBJV) has been contracted to construct the FGP, and once constructed, the FGP and associated infrastructure will continue to be owned and managed by the Gladstone Area Water Board (GAWB).

Benefits of the FGP include:

• Water security and reliability

• Continuous operation of Gladstone’s industry

• More than 400 jobs at the peak of construction

• Contribution to the growth of the Queensland economy

• More than 40 per cent of construction costs to be spent locally throughout project delivery

• More than 500 hours of training to the delivery team

• More than 25 apprenticeships and traineeships

• Target spend of $10 million with suppliers and businesses owned by First Nations Australians GAWB's Chief Executive Officer, Darren Barlow, said the Queensland Government’s decision to approve the pipeline for construction reflected the region’s importance to the state’s economy.

“The announcement by Premier Palaszczuk and Minister Butcher is pivotal in securing water for Gladstone’s industry as well as helping sustain the Queensland economy and provide jobs, and I thank the Queensland Government for their decision,” Mr Barlow said.

“Water security has been an ongoing, critical issue for Gladstone due to the single source water from Awoonga Dam.

“Four successive failed wet seasons resulted in a Low Supply Alert Declaration being issued in April 2021.

“As owner of the project, we look forward to the MBJV engaging with local suppliers to deliver tangible benefits to the Central Queensland region such as jobs, supply contracts and local capability raising.”

Current and ongoing works include obtaining environmental permits and approvals, detailed design,

procurement of subcontractors, equipment and materials, engagement with Traditional Owners, addressing land access arrangements and engagement with State Government, Gladstone and Rockhampton Councils and other interested stakeholders.

In preparation for the start of major construction, a pipe laydown yard, including a washdown area and a vehicle workshop, and a temporary workers accommodation are being established in Gracemere.

Earthworks for the laydown area and temporary accommodation camp commenced in June 2023 and these works are expected to be complete by late September or early October.

“While we estimate that at least 60 per cent of our construction workers will be from within the local area, we’re constructing a temporary workers’ accommodation camp to house workers from outside the region,” Mr Barlow said.

“We are aware of the high level of pressure on Rockhampton’s rental market at the moment and we have been careful to avoid adding any additional pressure to the market.”

On 23 June 2023, GAWB celebrated the arrival of the first pipe for the Fitzroy to Gladstone Pipeline. The pipe, manufactured and supplied by Steel Mains Pty Ltd, touched

down on site in Gracemere in anticipation for the start of major construction.

“The first pipe arrival was a significant milestone for the delivery of the Fitzroy to Gladstone Pipeline and is a great opportunity to ensure that this project is on Central Queenslander’s radars,” Mr Barlow said.

Due to the high-pressure water coming through the Fitzroy to Gladstone Pipeline, Mild Steel Cement Lined (MSCL) pipes are required to transport it safely. Almost 110km of MSCL pipe is being manufactured by Steel Mains, a Victorian-based manufacturer and supplier of complete steel pipeline systems.

MSCL pipe fittings, such as welded bends and special sections with instrumentation fittings, are being fabricated in Redbank, Queensland. The remaining 11km of pipe for the pipeline will be made up of High-Density Polyethylene pipe, and is being manufactured in Toowoomba, Queensland.

“MBJV have taken a local-first approach to procurement, and in instances where we have not been able to source materials within Central Queensland, we have worked diligently to ensure materials are being sourced from within the state and within Australia,” Mr Barlow said.

Construction commenced at the northern end of the pipeline corridor at the Fitzroy River Intake in Rockhampton in August 2023. Starting works involve construction at four waterway crossings, as well as pipeline construction from the Fitzroy River intake to Capricorn Highway. These early works include clearing and grading the pipeline construction zone, the transport, stringing and welding of pipe, trench excavation, sand deliveries and bedding, pipe installation, backfill and reinstatement.

The pipeline is expected to be operational in 2026, weather and site conditions permitting. Once constructed, the Fitzroy to Gladstone Pipeline and associated infrastructure will be owned and managed by Gladstone Area Water Board.

FITT RESOURCES KEEPS SYDNEY WATER PUMPING

Water industry operations need a helping hand to enhance productivity and operational output. The best way is to have the best quality industrial parts built for the unique conditions found in water plants. Chesterton provided quality solutions for FITT Resources to carry out integral upgrades by Sydney Water in 2022, leading to better equipment efficiency and performance outcomes.

Sydney Water provides water and wastewater services to the Sydney metropolitan, Illawarra, and Blue Mountains regions with an operational area of approximately 13,000km2. The network comprises water and wastewater treatment facilities, distribution/collection, and stormwater assets.

In July 2020, Sydney Water launched its new infrastructure and delivery model – P4S: Partnering for Success. This program would simplify procurement, optimise value, and deliver $4 billion of construction works and services between 2020 and 2030. Water and wastewater specialists FITT Resources successfully tendered to undertake work in three main areas: the repair and overhaul of submersible, centrifugal, and positive displacement pumping units.

PUMP REPAIR AND OVERHAUL

The scope meant FITT Resources would work on pumps from various manufacturers, all needing repair, maintenance and overhaul depending on the age, condition, location, and equipment use. Since the last overhaul in 2015, two tunnel pumps have started leaking excess glands due to shaft wear and packing degradation. As part of the “stop-gap” solution, they were repacked with Chesterton DualPac® 2211 1" section in a bull ring configuration at the bottom and sealing ring configuration on the top. This packing upgrade has been very successful in terms of the ongoing gland operation.

CHESTERTON 442 SPLIT MECHANICAL SEAL PROGRAM

FITT Resources was also tasked with upgrading and maintaining existing raw sewage pumps using Chesterton

CHESTERTON 442 SPLIT

MECHANICAL SEAL

442 Split Mechanical Seals. These pumps had been initially fitted with packing and then later cartridge seals. However, the decision was made to replace these with split mechanical seals. The seal set-up utilises either an API Plan 11 or 13, with close clearance or EnviroSeal SpiralTrac™ gland bushes. Additional benefits of the 442 mechanical split seals include protection and security for seal faces during installation, less heat under extreme pressure, and a compact gland design.

CHESTERTON ARC INDUSTRIAL COATINGS

All sewage units were rebuilt and reclaimed using a Chesterton ARC industrial coating, which was chosen to ensure that reclaimed casings and impellers are in the best possible condition to provide prolonged operational life in harsh pumping environments. Chesterton ARC coatings also offer protection against erosion and corrosion attacks, making it an ideal solution for potable water and sewage pumps. Using Chesterton's range led to an increase in efficiency, extended equipment life, and reduced downtime. The partnership between FITT Resources and Chesterton continues to be an important and fruitful one, with both companies constantly looking for ways to improve and innovate to increase plant operating life and reduce the cost of ownership.

THE JOURNEY TO FLEET SUSTAINABILITY

With more than 30 per cent of all CO2 emissions attributable to road transport, fleet operators have a major responsibility and opportunity to play a role in a greener future for our planet. The upcoming 3G end-of-life provides an excellent opportunity to improve the sustainability of fleet transport.

As the impending 3G shutdown forces all fleet operators to upgrade hardware to stay connected, this provides an opportunity to also consider the broader role that telematics can play on the journey of sustainability we must embark on.

While fleet operators have no choice to delay upgrades past June 2024 in order to stay on the air, proactive planning can minimise disruptions and ensure continued efficiency and productivity. However, logistics and supply chain will become increasingly challenging as the 3G end-of-life approaches and the time to act is now.

Nova Systems provides its in-vehicle management system (IVMS) to a number of key clients with large fleets across Australia. In partnership with Geotab, which supports close to 3.5 million vehicles on the road across the globe, Nova Systems has access to intelligence from the largest and fastest growing fleet of electric vehicles on the planet.

Nova Systems Director of Business Development and Alliances, Paul

Weiss, said that the experience and intelligence of real-world electric vehicle (EV) performance allows unprecedented insights for planning, implementation and operations.

“Nova Systems, in conjunction with Geotab, represents a world-leading value proposition in Australia for traditional and future EV fleets,” Mr Weiss said.

“By harnessing the power of 4G networks, EV telematics can be taken to the next level, with faster and more reliable data transfer and more advanced analytical capabilities.

“This will enable EV owners and fleet managers to make more informed decisions, reduce downtime and maintenance costs, and ultimately maximise the value of their assets. We acknowledge that the 3G to 4G migration is a disruption; but it makes sense to use it as an opportunity to join the leaders in fleet sustainability.”

Geotab Associate Vice President Sales – APAC, David Brown, said, "Fleets need to understand the

operational impact the 3G shutdown will have on their organisation.

“There are a number of very important factors that need to be taken into consideration when choosing when you transition and whom you choose to work with.

“How long will vehicles need to be off the road for? Can you get replacement stock quickly? Are there installers available to undertake the task? Is the technology a good fit for future requirements? All these factors are crucial in making a decision.

“With Nova Systems and Geotab, we merge ease of install with our readiness to provision hardware quickly from our 3PL in Australia, also having the latest scalable technology to adjust as your business evolves for compliance, safety, data insights and sustainability."

After six months of full operations, a fleet’s utilisation record can then enable EV vehicle matching and charging infrastructure assessment.

HOW RECYCLED WATER

can make green energy even greener

As the country works to meet renewable energy targets, recycled water has an important role to play, both in the generation of this energy and in ensuring that the burden of the transition to net zero is not placed on drinking water reserves.

Renewables will soon replace non-renewables as the main energy source for our homes, businesses and communities, helping us fight climate change and create a more sustainable future.

But there is one thing we often forget when we discuss renewable energy: our most precious natural resource.

Water is not only essential for life but also vital for many forms of renewable energy production, often in significant volumes.

With water security and water stewardship becoming increasingly pressing issues right across the country, questions are being raised about how energy production may impact our waterways and drinking water stores.

Urban Utilities is the primary provider of drinking and recycled water in South East Queensland, a region all too familiar with water scarcity after the Millennium Drought.

Recycled water is highly treated wastewater that is safe and reliable for various commercial, agricultural, and industrial purposes and processes. Most importantly, it can also be used to produce green energy without affecting drinking water reserves.

General Manager Water Ventures at Urban Utilities, Matt Magee, is a leading industry advocate for using recycled water to enhance renewable energy production.

“Over the past couple of years, I have been doing a lot of work with companies that are looking to improve the sustainability of their water use, and at the same time working with various stakeholders to enable green economic development, in particular through green energy production,” Mr Magee said.

“The overwhelming majority of our key commercial customers now have explicit water stewardship goals in their corporate targets, some of which are also reflected in debt covenants or end-product sustainability standards.”

A recent Urban Utilities study has reported a strong demand for recycled water from traditional industries, as well as new industries such as green hydrogen – a demand that will likely triple by the time Brisbane hosts the Olympics in 2032.

They are currently engaging with existing businesses and emerging renewable energy producers to identify and meet their evolving water needs. Many are surprised to discover the range and value of the utility's recycled water solutions.

“As the world transitions to more sustainable sources of energy, and as climate change exacerbates drinking water scarcity, recycled water is emerging as a compelling solution to both challenges,” Mr Magee said.

“Energy is only truly sustainable when the water used to produce it is too.”

SOLAR FARM POWERING WASTEWATER TREATMENT IN WODONGA

As Australia’s energy grid transitions towards renewables, water utilities also have a large role to play in reaching net zero emissions targets. North East Water is powering ahead and investing in a renewable energy source for its wastewater treatment plant.

Anew 3MW solar farm is now powering the Wodonga Wastewater Treatment Plant with renewable energy. In a major step towards North East Water’s ambitions to reach net zero emissions by 2035, the 6,500-panel solar farm will reduce the Corporation’s carbon footprint by 20 per cent or 6,000t of carbon dioxide equivalence every year.

The $9 million solar farm, which uses a single-axis tracking system to increase solar capacity, is already generating more than enough electricity to power the plant during daylight hours, with surplus energy being fed into the electricity grid and offsetting power used at other sites.

North East Water’s effort to reduce its carbon footprint is being driven by the Statement of Obligations (Emission Reduction), which formally commits Victoria’s water corporations to achieve net zero by 2035.

Managing Director, Jo Murdoch, said the solar farm is a shining example of how customer bills are being reinvested into projects and services that will benefit them directly.

“Not only is this project significantly reducing emissions which is good for the environment, it's also reducing energy costs which helps to keep downward pressure on customer bills," Ms Murdoch said.

“We recognise Wodonga is a fast-growing region with a population and industry that is only set to grow.”

The solar farm project demonstrates the Victorian water sector’s leading contribution to reach net zero by 2035,

with this government initiative putting Victoria’s 18 water corporations at the forefront of emission reductions.

“The new solar farm is part of North East Water’s major investment in new and upgraded infrastructure to improve services for our customers and to build climate resilience,” Ms Murdoch said.

Environment, Systems and Operations General Manager John Day said buffer zones around wastewater treatment plants enabled solar farms to be built.

“At our seven other treatment sites, where we don’t have land availability, we can put surplus energy generated here into the grid and extract and use it through a virtual metering network,” Mr Day said.

Victorian Government Water Minister, Harriet Shing, said Victoria’s state-managed water sector is the first in Australia to commit to net zero emissions by 2035.

“Our water sector is leading the nation on emissions reductions – showing consumers and industry that we can tackle climate change and boost renewable energy use as our population grows,” Ms Shing said.

These targets also put the Victorian water sector alongside the United Kingdom as the world leader in water sector emissions reductions.

Delivering the Statement of Obligations (Emission Reduction) is a significant milestone for the government, and the state’s water sector, as we all work towards a net zero emissions future.

PIONEERING SUSTAINABLE

RENEWABLE ENERGY SOLUTIONS

As renewable energy gains importance in our pursuit of sustainability, there are several challenges that need to be addressed to accelerate its adoption and maximise its effectiveness. Some of these challenges include intermittency and reliability. Renewable energy sources, such as wind and solar, are intermittent as they do not produce power consistently. Ensuring a stable and reliable energy supply is a significant challenge that can be addressed through energy storage solutions, grid improvements, and demand-side management.

The integration of renewable energy sources into existing grids can be both complex and expensive. Simultaneously, modernising and upgrading grid infrastructure to accommodate distributed energy generation is essential. Additionally, large-scale renewable energy projects, such as solar and wind farms, often require significant land use. Balancing the need for renewable energy with environmental conservation and land use concerns remains an ongoing challenge. Developing resilient supply chains is crucial, and from a technological innovation perspective, continuous research and development are required to improve the efficiency and effectiveness of renewable energy technologies in order to make them more accessible and cost-effective.

SWITCHING ON: POWERING UP HOMES WITH COMMUNITY BATTERIES

Community batteries are flexible and scalable energy solutions that benefit both the local communities they are built in and the wider energy system. Ausgrid is collaborating with the Federal Government to deliver a major community battery rollout, which will see as many as 400 batteries powering neighbourhoods across Australia.

The Community Batteries for Household Solar Program will support power quality and voltage in local areas, and is expected to enable up to 100,000 households to install more solar and feed their excess energy back into the grid, while supporting home electrification and electric vehicle charging.

The program will be funded with $200 million dollars delivered through the Department of Industry, Science and Resources, and the Australian Renewable Energy Agency (ARENA).

The batteries will also provide system-wide benefits, supporting more intermittent renewable energy generation by bridging the gap between when that energy is generated and when it is needed.

On 8 September, the Federal Minister for Climate Change and Energy, Chris Bowen, joined with Ausgrid CEO, Marc England, and Member for Reid, Sally Sitou, for the official launch of the first of these batteries at Cabarita in Sydney.

The 412kWh community battery means that excess solar generated by Cabarita homes can be stored locally during the day – reducing the need to buy more expensive power from the grid when the sun isn’t shining.

Cabarita is the first of six planned community batteries to be rolled out across Sydney and the Central Coast as the first phase of the program, with the remaining five to be installed in Bondi, Cammeray, Narara, North Epping and Warriewood over the coming months.

To support its community battery roll out under the Community Batteries for Household Solar Program, Ausgrid will also be co-installing community-based renewable energy projects to further increase access to the renewable energy transition. This starts with a 42kW solar array on the Cabarita Swimming Centre, which is more than six times the size of an average household solar system.

Mr Bowen said that the new Cabarita battery would help residents store solar energy locally and reduce emissions.

"I’m delighted to launch the Federal Government’s first Community Battery – which will help households access cleaner, cheaper energy and increase grid resilience,” Mr Bowen said.

“These community batteries allow communities to see, in a very real sense, that the solar panels on their roofs aren’t just overloading our grid with power during the day, but that it is being stored for the night when we need to draw on that power.”

Ms Sitou welcomed the announcement, and said that she was thrilled to see the Cabarita community battery up and running.

“The community battery is one example of how we can better harness all the good work that the community is doing around putting solar panels on their roofs,” Ms Sitou said.

“It also shows the commitment the government has to sharing the benefits of clean and renewable energy with all households.”

The Cabarita community battery is another important step toward retailers providing a community storage service to their customers, so everyone can access the benefit of battery storage without having to install an expensive home battery, ultimately pushing down the cost of their energy bills.

Looking to the future of community batteries

Mr England said that Ausgrid was proud of the launch of the first of 400 batteries nationally to be installed as part of the first round of funding.

“As more solar goes on rooftops, the grid becomes more difficult to manage as the electrons are flowing in multiple directions,” Mr England said.

“So local batteries like this play a really important role in shoring up the grid, but also enabling more electrification in the future as more people convert to electricity, as it becomes more renewable and more EVs are adopted, and ensuring that we don’t have to build the grid as big as we otherwise would because we have batteries like this exporting at the end of the day.

“That allows us to keep costs down over the medium to long term.”

Mr England said that the community batteries will allow residents to install more solar on their roofs, and tap into the same amount of storage capacity as they would be able to if they had a personal battery installed in their home, but at a much cheaper cost.

“We estimate New South Wales consumers could save up to $20 billion if community batteries replaced half the expected home batteries, with the added benefits of continuing to put downward pressure on peak energy prices while maintaining grid stability.

“In addition, community batteries take advantage of our existing network infrastructure, speeding up installation time and reducing the need for expensive network augmentation.

“By 2030, with the right regulatory arrangements, we could deliver more than 1–2GW of storage, leading to increased electricity system security and reliability for our customers.

“So we are really excited about what these batteries will provide, this is the beginning of a journey. We’d like them to be bigger, in fact we are looking at batteries that are probably 25 times the capacity of this one that we will soon be putting into substations in Ausgrid land.”

Mr Bowen thanked the team at Ausgrid for their speed and skill in installing the battery, and congratulated Cabarita on its launch.

“Cabarita is able to say ‘there might be 399 coming later, but we were the first in Australia.’”

BOULDERCOMBE BATTERY PAVING THE WAY

FOR RENEWABLE ENERGY STORAGE

The Bouldercombe Battery Project (BBP) will be one of the first standalone large-scale Battery Energy Storage Systems (BESS) in Queensland and is the first fully commercial project financed battery in Australia. Australian company Genex has partnered with Tesla and Powerlink to operate the battery. We spoke to Genex Chief Executive Officer, Craig Francis, to hear more about the project’s funding, goals and milestones.

As Australia works towards net zero emissions and renewable energy targets, energy storage has become a hot topic. Generating renewable energy is only part of the green energy transition – energy storage plays a key role in maintaining grid availability and maximising the energy generated by renewable sources. Many renewable sources generate the most power when there is least demand, so to avoid losing out on valuable resources, energy storage is paramount.

Genex Power is an ASX-listed company focused on developing a portfolio of renewable energy generation and storage projects in Australia. Genex’s diverse portfolio currently includes large-scale batteries, pumped storage hydro and wind and solar production across Queensland and New South Wales.

The company’s flagship Kidston Clean Energy Hub, located in North Queensland, integrates large-scale solar generation with pumped storage hydro and wind energy. Genex’s

first battery energy storage system – the Bouldercombe Battery Project (BBP) located in Central Queensland – is a 50MW/100MWh battery, set to be one of the first BESS set up in Queensland.

The BBP was developed after successfully achieving financial close followed by the commencement of construction of Genex's Kidston Hydro project. While the Kidston project delivered outstanding results in hydro energy production, it highlighted the need for a standalone battery project to take on additional storage. With the Kidston project located in North Queensland, the location for the BBP wasn’t hard to choose – the Bouldercombe site presented the perfect conditions for a large-scale battery installation. Genex partnered with Powerlink, who provided the land and grid connection.

Genex Chief Executive Officer, Craig Francis, said, “In terms of how we landed at Bouldercombe, we did a little site visit driving through Central Queensland looking at various substations. The concept was to find a good area of land in a good part of the network where there's good interconnection and good system strength, but also where we could get a parcel of land that was as close as possible to the substation.”

Consolidated Power Projects were employed as the plant contractor, providing the interface between Powerlink and the battery.

MITIGATING RISK

Genex wanted to keep the project entirely commercial, meaning that the project would not receive any government funding. Traditionally, commercial battery projects have been difficult to execute due to market risk. Market risk refers to the potential difference between the energy purchase price and the energy sale price. When the battery charges, it draws electricity from the grid, paying the spot price at that time. When it discharges, giving energy back to the grid, it receives the spot price at that time. This exposes the operator to potential loss if the cost price is greater than the sale price.

When battery projects are government-funded, the government offtake process absorbs the market risk. While this can be helpful in mitigating potential losses for independent companies, it can also impact the ability to generate any profit from battery projects – profit that can then be reinvested into more renewable energy. The BBP is the first project financed in the National Electricity Market that is completely commercial. For Genex, keeping the project upside for its shareholders was crucial from an economic perspective.

“With our hydro project, the revenue structure that we were contemplating and that we ultimately agreed with EnergyAustralia basically gives them full control over the project and they pay us a fixed fee,” Mr Francis said.

“So really, all this work we've been doing on the dynamics of the energy storage market, and how it all works and the economics of it was a bit redundant in the end, because we don’t get to capture that upside. We receive a fixed rental fee, which is great for supporting project finance for a large complex project like the hydro, but really means we've got little upside.

“We looked at Bouldercombe specifically with the idea of broadening our storage strategy and capturing more of

those economics, which we've got a great understanding of in Queensland. We'd been working on our flagship Kidston pumped storage hydro project since the company was founded in 2014. "We learned a lot about energy storage in Queensland and the pricing dynamic, the economics that underpinned energy storage. We wanted to apply that knowledge more broadly than the hydro project to another standalone storage project and we knew the need for it was there."

PRUDENT PARTNERSHIP

In order to deliver the project without government funding, Genex partnered with Tesla. The Bouldercombe battery is powered by the Tesla Megapack, which stores energy for the grid reliably and safely, eliminating the need for gas peaker plants and helping to avoid outages.

Along with the Megapack, Tesla delivered underwriting for the project, meaning that Genex is guaranteed a minimum revenue and share in higher profits. The underwrite not only reduces the market risk for Genex, but also ensures both partners benefit the more the battery is used and the more renewable energy is generated. It’s a great structure for both parties – and for the environment.

“It's a deliberate risk that we are accepting. We think there is a lot of upside there. One way to mitigate against it would be to give that risk to somebody else, like EnergyAustralia or Origin. But we think in doing so, we're leaving a lot on the table. So we're taking that risk on this project, because it's only a risk above the Tesla guaranteed revenue amount. We're taking on this risk because we have a portfolio perspective, a largely fully contracted portfolio. Of our portfolio, 83 per cent of our revenues to 2055 are contracted, meaning 17 per cent are exposed to this market risk,” Mr Francis said.

The partnership also includes use of Tesla’s proprietary algorithm-based bidding system, Autobidder. Autobidder is a real-time trading and control platform that provides value-based asset management and portfolio optimisation,

enabling owners and operators to configure operational strategies that maximise revenue according to business objectives and risk preferences. Essentially, Autobidder determines the best times for the battery to intake and discharge energy from an economic perspective – benefitting both Genex and Tesla.

“The revenue structure is basically, Tesla operates the battery to make as much money as possible, they've got the technology they use to do that. But what they also provide is a revenue underwrite, so there's a minimum level of revenue they'll guarantee. In reward for that, they get a share in the outperformance above that underwrite.

“It's really an alignment of incentives. We both want to make as much money as possible. We both earn more the more we make, but we're protected on the downside through the Tesla underwrite. We think it’s quite an innovative structure, it’s enabled us to get some stability into the project. It gives us some downside protection, but also gives us that upside exposure, which is what we were looking for at the outset for the project,” Mr Francis said.

“We think it's pretty innovative being one of the first to attract project finance and get delivered purely on a commercial basis, without any support. And hopefully, what that's doing is paving the way for others to adopt similar structures. The banks that we spoke to have now seen one done, seen how it can be successful, and that feeds into their appetite for more projects with similar exposures. You build an industry by doing these things and that's certainly what we're doing.”

Under the partnership agreement Tesla also agreed to warrant and operate the battery for 20 years, including physical maintenance at site.

SWITCHING ON

The BBP is an ambitious and innovative project. Despite many variables that either present risk or are so cutting-edge that there is no blueprint to follow, execution of the project has been smooth. So far, Genex has not experienced any major hurdles or delays – that’s even despite early parts of the project occurring during the COVID19 pandemic. Although supply chain impacts affected the procurement of materials for the project, workarounds were found and the project stayed on track.

The BBP is set to be delivered on time and on budget. Energisation has already been achieved on the project, an exciting milestone. Energisation means the battery is connected to the network and is currently undergoing commissioning tests to achieve full functionality. During this phase, the battery is still able to be used for simple charging and storage.

“We're just operating that simple profile of just, charging it in the middle of the day to absorb all the extra solar and discharging in the evening to meet the evening peak. You have this battery sitting there, all this extra solar in the middle of the day and all this extra demand in the evening. So it's great that we can use it just to earn a little bit of revenue, but also support renewables and the grid,” Mr Francis said.

“The project is built and it's connected to the network. It's now going through the commissioning phase, which is basically a series of tests with the Australian Energy Market Operator and Powerlink, the government-owned network. There's various tests that need to be performed and signed off on. Once they're signed off, we'll be announcing the project has reached practical completion, which is basically completion under the contract. That's when the offtake agreement Tesla commences.”

Genex said the project is on track to meet its projected timeline of full operation in October 2023.

BIG IMPACTS

The ever-changing landscape of renewable energy has already encouraged Genex to think about Bouldercombe’s future. When the project was initially developed, 50MW was a large-scale battery. These days, not so much. Mr Francis said that the company is already considering expanding the BBP’s capacity to 100MW.

“50 megawatts is small these days, it wasn't when we committed the project back in 2021. But what it does do is it provides the pathway for other projects, it shows that this can be done without government support, with conventional financing and hopefully it will enable more participants to come and deliver similar types of projects, because we're going to need them. And certainly for us, it will give some track record as well for us to go and do more projects, including potentially an expansion of Bouldercombe. We also have land and planning approval for an additional 50MW, 100MWh, which is something we're continuing to explore.”

Bouldercombe isn't going to single-handedly complete the transition, but it will contribute. Genex has already announced another project it acquired in August 2022, located at Bulli Creek in Southern Queensland. That site is currently powered with 2GW of solar, and Genex is currently looking at installing a 400MW battery at the site.

“We've announced a project at Bulli Creek, which is west of Toowoomba, right near the connection between Queensland and New South Wales. It's called the Queensland–New South Wales Interconnector. That's a big site with huge capacity, it’s got up to 2GW of solar and battery capacity. So we've announced that we’re looking at a 400MW battery there, that remains a priority site for us. We're turning our minds to what could be, to add something there, under a similar structure or something slightly different to Bouldercombe,” Mr Francis said.

Executing a 100 per cent commercial battery project is no small feat – but the BBP is proof that with the right partnerships, it is definitely possible.

The interview with Craig Francis was conducted on 20 September, prior to a minor fire incident at the BBP site. The root cause of the incident is under investigation.

LOST TREASURE:

reclaiming the wonder wastes driving the energy transition

Australian utilities are sitting on a bounty of untapped biogas that has the potential to transform the energy landscape, supercharge a site’s energy efficiency and drastically improve their bottom line. Here we discuss how this untapped resource can drive the energy transition.

Waste to energy technologies that harness the power of biogas are mature and transformative solutions that achieve the dual benefit of waste management and contribute to decarbonisation. But Australia’s 250 or so working biogas plants is a number that is remarkably shy of the more than 20,000 biogas plants operating in Europe, where biogas is routinely captured from landfill sites, wastewater treatment plants or processing plants and turned into heat and power.

Eneraque Renewables has been providing waste to energy technologies for utilities for more than 40 years. The company’s CMO, Heather Millar, said that Australia is poised to fully embrace the biogas opportunity.

"Technological advancements and financial incentives are key drivers for the successful implementation of these technologies.

“Landfills and wastewater treatment plants are ideal candidates for biogas technologies, as they co-locate a high quality feedstock source and consume significant amounts of energy, a combination that makes these projects financially viable, simple to build, and operationally sustainable,” Ms Millar said.

Eneraque Renewables has worked with landfill and wastewater clients across Australia and New Zealand since the early 80’s. Over that time, the technology has continued to improve and scale, with solutions no longer stopping at simply flaring off the biogas.

These specific technologies can be used in isolation or Eneraque Renewables can take it a step further and build an entire plant from idea to completion from its Brisbane Manufacturing Hub.

“We specialise in full EPCM of biogas plants and equipment in Australasia, including waste to energy technology, CHP, anaerobic digestion, biogas storage, flaring and scrubbing, and biomethane to grid injection,” Ms Millar said.

As an example of where technology is heading, landfill gas collection systems now include an intricate network of wells and pipes strategically placed throughout the landfill to capture methane as it is released. Advanced systems incorporate automated controls and monitoring to optimise gas collection efficiency.

Plants also often employ conditioning and pre-treatment systems to remove impurities from the collected gas. This includes removing moisture, hydrogen sulphide, and other contaminants that can harm equipment and reduce the quality of the gas.

“Ongoing maintenance of the plant is usually a consideration for our clients,’ Ms Millar said.

“So if they don’t have the expertise or simply don’t want to house in-house maintenance, we offer a full ongoing maintenance program and dedicated biogas technician, if required.”

Remote monitoring and control systems that allow operators to manage gas collection and power generation remotely now form part of each plant design. These systems enhance efficiency and enable rapid response to changing conditions.

“We’re on the journey to net zero, and we believe that renewable gases are a critical part of the journey. Utilities can become energy-neutral or even energy-positive through innovative biogas technologies,” Ms Millar said.

"Landfills and wastewater treatment plants are teeming with energy potential. It’s a treasure trove waiting to be tapped."

A FASTER SMART METER ROLLOUT FOR A SMOOTHER ENERGY TRANSITION

By Anna Collyer, Chair of the Australian Energy Market Commission

As the once-in-a-generation transformation of the power system continues, the way customers interact with energy in their homes is also changing. The Australian Energy Market Commission is now recommending electricity smart meters in 100 per cent of households by 2030 as a critical step to realising benefits for both.

The past few years have been big for energy. We have seen widespread commitments from the Australian government and jurisdictions to achieve net zero by 2050.

Industry, governments and market bodies are, for the first time, united in our collective effort to achieve Australia’s ambitious target and every other week there seems to be a new advancement, or initiative, edging us toward our goal.

One of the greatest advancements for the transition is happening in homes across the country. Customers are increasingly investing in what we call consumer energy resources, or ‘CER’ – such as solar panels, battery storage and electric vehicles at a rapid rate.

THE CHANGING LANDSCAPE

A high proportion of Australian residences already have solar PV, with around 3.19 million total solar rooftop PV systems installed for residential and small business customers in Australia, while more than 50,000 total registered small-scale battery systems have been installed in Australia in the past seven years. There will also be a surge in electric vehicles in Australia, with 92 to 99 per cent of all vehicles expected to be electric by 2050.

As it stands, small-scale rooftop solar systems together provide more than 17GW of capacity across the national electricity market – that’s more than four times the generation capacity of Snowy Hydro.

All of this consumer-generated power presents both a great challenge and opportunity for eastern Australia’s electricity system. But, if we can – pardon the pun – better harness the power of all of this CER, we can fill reliability gaps in the future to improve operation of the overall system.

SMART TECHNOLOGY

What has this got to do with smart meters you might ask? And how does this lead to benefits for customers? Smart meters present clear benefits for consumers and form a crucial link for the wider energy system, paving the way for significant advances necessary to reach net zero.

While smart meters are not new, our recent review has found that they will be a vital building block in helping us transition to a more efficient, lower-cost and decarbonised energy system sooner.

As an independent statutory body and the rule maker for the energy sector, the AEMC’s job is to work with stakeholders including market bodies, industry groups and consumer advocacy bodies to make sure the right frameworks are in place for an affordable and reliable energy future for customers.

Smart meters offer consumers more opportunities when it comes to how they directly use and pay for energy. A number of Australians are already using smart meters to cut bills, from those who have CER to customers without solar, batteries or an EV who may be using smart meters to access cheaper tariffs such as the ‘solar soaker’. In the not-too-distant future, smart home energy management systems could also help customers manage their energy use throughout the day leading to cheaper bills overall.

By monitoring energy use digitally and with accuracy, smart meter technology also creates the opportunity for greater data sharing and visibility of consumer assets for the energy market. This, in turn, leads to better system planning and decision-making and fewer unnecessary costs being passed down to consumers.

ACCELERATING FOR TOMORROW

To date, the approach for rolling out smart meters has been slow, and less efficient than it could be. Outside of Victoria, the average smart meter take-up level in each jurisdiction is at around 35 per cent.

Deployment of smart meters in the national electricity market has largely been driven by consumer requests to install solar PV systems and by new connections, such as when a home is built. Retailer-initiated smart meter programs have been few and far between.

Where smart meters have been installed, the scope of services offered to consumers has been narrow. And it means some consumers without CER are not seeing enough direct benefits to want to request a smart meter.

The AEMC’s comprehensive review into smart meters has found that speeding up the rollout of smart meters to 100 per cent of households by 2030 would provide net benefits to the value of $507 million for national electricity market regions New South Wales, Queensland, the ACT and South Australia.

In our final recommendations, cost savings would be made through a coordinated rollout led by energy networks developing a legacy meter retirement plan, with retailers overseeing upgrades to smart meters between 2025 and 2030.

The first step in this plan would be for retailers and networks to map out a year-to-year schedule of the deployment program – focusing on how to minimise installation costs and maximise the benefits for customers.

Ensuring a positive experience for customers is key. That’s why the AEMC is recommending better information and protections. Among these, would be requirements for retailers to provide clear notifications ahead of installations and any changes to billing arrangements.

In addition, we’re recommending an overarching communication strategy so that customers are better informed about rollout plans and how they can use a smart meter to directly save money on their power bill.

Without low-cost, timely access to data, many of the benefits available from smart meters and other reforms will simply not be realised.

Data opens up new possibilities for innovation, where new technologies and services can be provided for consumers, at home, in their community, and perhaps, even in coordinating or orchestrating the use of CER in the system.

Another of our recommendations is in ensuring access to data for customers and networks.

We are recommending a mandate on free customer access to real-time data about their own energy usage, so that they can maximise their savings from the touch of a device in their own homes.

We’re also recommending networks have access to granular power-quality data. This information can improve the operation and use of existing infrastructure to assist networks in lowering the cost of CER integration.

Yesterday’s electricity system relied on the 19th century technology of accumulation meters, but for the net zero emissions system we aspire to build for tomorrow, we need more advanced technological devices.

We need smart meter devices in every home to bring our system into the 21st century.

RETAIL BILLING & CRM

As the cost of living increases, energy bills are placing more and more financial pressure on consumers. In this article the Australian Energy Council (AEC) takes a look at the government reforms currently underway, and how they might impact retailers’ already supporting customers experiencing payment difficulty.

Alot has been written about the high cost of living, and the impact on the ability of customers to pay their energy bills. With the Default Offers in Victoria, New South Wales, South Australia and Queensland increasing by around 25 per cent, the pressure on energy bills is mounting. So what are governments and regulators doing to support customers to manage high energy costs?

FEDERAL GOVERNMENT INITIATIVES

Energy Bill Relief Plan

In his May Budget speech, Treasurer Jim Chalmers highlighted the effectiveness of the Federal Government’s interventions at the end of 2022, advising Australians that power bills would be around 25 per cent less than they would otherwise have been. But prices would likely remain high, and to counter the impacts, the Treasurer announced $3 billion in relief – co-funded with the states – to deliver up to $500 off the energy bills of 5 million Australians in the coming financial year.

This announcement was welcomed by industry and customer groups alike, but its implementation has been far from smooth sailing. For energy retailers already grappling with a long list of regulatory changes to be implemented in 2023, a new program with great complexity has been a challenge. Positively, the Government has worked closely with industry to develop a delivery mechanism that will see most eligible customers automatically seeing the payment on their energy bills without the need for additional action. Customers already receiving government funded concessions and rebates from their retailer have now received the first bill relief payment directly on their bills.

However, for many customers – in particular those eligible under the bill relief package but not for energy concessions – the process has been more challenging. These include approximately 1.2 million Australians receiving payments like Family Tax Benefit and Carers Allowance. In September, these customers were sent a letter from Services Australia, advising them of their eligibility, directing the use a portal linked to their MyGov account to provide consent to share personal details with their retailer.

This relatively cumbersome process highlights the complexity of utilising exceedingly automated systems to deliver ad hoc support measures. While no doubt well-meaning, the Federal Government’s commitment to delivering the payment to a group of customers broader

GOVERNMENT ENERGY BILL RELIEF MEASURES:

HOW DO THEY STACK UP?

By Ben Barnes,

than those currently receiving concessions creates a problem with information asymmetry. Retailers know their customers, but not their eligibility, while the Government knows if a person is eligible, but not which retailer they are a customer of. The AEC is confident that customers will ultimately be able to navigate the Services Australia process simply and quickly, but any hurdles in a process will always result in customers missing out – a particular concern when seeking to support vulnerable customers doing it tough.

The other challenge in implementing a program as broad as the Energy Bill Relief Payments is the how the payment is designed, a point that should be considered if another targeted support package is to be implemented in the future.

Retailers operating highly complex billing systems in heavily regulated environments cannot turn features on and off with ease. Every ‘feature’ is a challenge when implementing, creating an opportunity for errors that result in customer confusion in the best case scenario, and customers missing out on what they are entitled to in worse cases. The energy bill relief payment of $500 is split differently in each jurisdiction. Most customers will receive $125 per quarter for a year, while others will receive $125 upfront, and another $125 early in 2024. This split of the payment meets an important policy objective – that is, spreading out the payment to reduce bills over a longer period of time. This is intended to avoid a once off ‘sugar hit’ putting further pressure on inflation, but also, in an effort to reduce the cost of energy in the Reserve Bank’s “basket of goods” over a 12 month period to reduce inflation. But this complexity will increase the challenge for retailers, and will see customers who move house or switch retailers likely miss out on later payments.

With retail prices likely to remain elevated into 2024, the AEC anticipates calls to again provide bill relief in the next financial year. It will be important to ensure any repeat scheme is as simple as possible and targeted to customer cohort’s already known to retailers to ensure that benefits flow through to those who need them most.

Energy performance and home upgrades

The May budget also pointed to energy efficiency as a means of reducing customer bills. The Federal Government provided $1 billion to the Clean Energy Finance Corporation as a means of enabling low-cost loans to be delivered through banks for home upgrades such as double glazing, insulation, and rooftop solar. Another $300 million was offered to the states to make performance upgrades to social housing.

While these initiatives will likely lead to bill reductions over time, they won’t make a material difference in the next 12 months. To date, while three of the big four banks offer green loans on their website, only the Commonwealth Bank offers a product with an interest rate materially lower than their standard variable home loan. No data is available about its take-up, but hopefully as more customers become aware of the opportunities, in addition to the increased incentives caused by high energy bills, more and more customers benefit from lower bills in the coming years.

Financial Counselling Industry Funding Model

The Federal Government is also progressing its model that would see a broad range of industries providing voluntary contributions to support the financial counselling sector. The scheme initially set out to receive $18 to $20 million per year between 2024 and 2026 that would be distributed directly to financial counsellors to enable better service delivery. Media reports suggest the Federal Government will receive commitments from the banks, energy, insurance and online gambling, with telecommunications, water, and the finance industry not participating in the first iteration of the scheme.

The scheme, provided adequate support is received, will be implemented from January 2024. This is a stretch, and it will be critical that the development of the body isn’t rushed to its detriment. It will also be critical that the body is set up with a clear governance framework and set of objectives that set it up for long term success – providing certainty for the sector, and enabling important support for customers that are doing it tough by paying all of their bills, not just their energy bills.

REGULATOR INITIATIVES

The Australian Energy Regulator is continuing to implement its Towards Energy Equity Strategy, which seeks to reduce barriers to participation, support customers experiencing payment difficulty, ensure that the consumer voice is heard in energy consultations and improve energy affordability.

Central to this strategy is its Game Changer project, designed to identify and promote fundamental changes to the energy sector’s support frameworks to better share the costs of providing increased levels of support to vulnerable customers.

The project is nearing completion, and some ideas being considered would deliver material benefits to vulnerable customers if able to be implemented, but unfortunately there are no easy victories in this space. Key reform opportunities with broad support include ensuring all eligible customers gain access to energy concessions and enabling vulnerable customers to be moved to a retailer’s best offer without requiring consent. Other reforms are more contentious, and from the perspective of the AEC lead to more costs than benefits. These include the implementation of a central service body to manage retailer hardship functions, and a social tariff to reduce costs for vulnerable customers, with the costs socialised amongst others.

It is too early to tell where the regulator will land on its Game Changer, but given the options on the table, it is unlikely that any changes would be implemented before mid-2024 at the earliest.

It’s hoped that these policies will go some way to providing additional support to customers in meeting their energy costs. As the benefits of longer-term reforms flow through, retailers will continue to work hard to support their customers through the provision of short-term payment arrangements, longer term hardship agreements, and other bill relief to ensure vulnerable customers are effectively supported, mitigating the risk of unsustainable energy debts.

CREATING CYCLES. FOR LIFE.

DOUBLING DOWN ON MELBOURNE'S WASTEWATER NETWORK

As Melbourne’s population continues to grow, maintaining and upgrading essential infrastructure is a must. More than 5 million people already live in the city, which means sewerage systems need to be able to handle a staggering amount of waste.

The Hobsons Bay Main Sewer is responsible for 30 per cent of Melbourne's wastewater, by transporting it to the Western Treatment Plant. The sewer main was constructed in the 1960s, and is quickly approaching the end of its service life.

As such, the Hobsons Bay Main is sorely in need of an upgrade and will need to be cut off while works are underway, but the needs of Melbourne’s waste network can’t be put on hold so easily.

To ensure everything keeps flowing smoothly, Melbourne Water is funding a $206 million duplication project to reproduce the sewer, which will support the network while the original main is upgraded to modern standards.

Early works for the project began in 2021 and construction is expected to be completed in mid-2024.

Tunnelling works began in August of 2023, with Melbourne Water’s tunnel boring machine – named Lucey – operating at depths of between 24.5m and 27m below the surface of the Yarra, alongside the original sewer main.

The new 670m Hobsons Bay Main Sewer will stretch from Westgate Park, Port Melbourne to Scienceworks in Spotswood, under the Yarra River.

Melbourne Water’s Managing Director, Dr. Nerina Di Lorenzo, said that this major project forms part of a broader Melbourne Water capital infrastructure program that will enhance the reliability of the city’s sewerage network and services for the benefit of Melburnians today and for generations to come.

A COLLABORATIVE EFFORT

The extensive project is a joint effort between the Victorian Government, Melbourne Water, John Holland and Museums Victoria.

Dr. Di Lorenzo said that Melbourne Water is working hard to ensure that business as usual can continue for its neighbours, like Scienceworks and Grazeland, while considering the needs of the community and the impact these works have on everyone.

“We also have a close working relationship with the team at John Holland, who we appointed to construct the duplicate sewer,” Dr. Di Lorenzo said.

“Melbourne Water and John Holland project teams have been working on this for three years. We’ve established two working sites at Spotswood and Port Melbourne, constructed four shafts and started tunnelling works

James Le, Melbourne Water the Hobson Bay Main Sewer duplication, said that collaboration has been central to the company

“We’ve developed a strong partnership with our delivery partner, John Holland. Our partnership extends over three years on this project, but has been ongoing as our long term partner on the Major Capital Delivery Water Framework,” Mr Le said.

“Our commitment to safety is of utmost importance to both companies. On the ground we hold joint safety forums, and mental health and wellbeing toolboxes, and these serve as a platform where we mutually learn from each other’s experiences, refining our practices for a safer work environment.”

John Holland Project Manager, Lucas Martinez, said that John Holland’s long-standing relationship with Melbourne Water spans over 20 years, including multiple tunnelling and deep sewer projects.

“With any project, it’s important to work directly with the client, and in all my experience I have found that open and transparent communication is the key to successful project delivery,” Mr Martinez said.

as Melbourne Water) as a scientist at the Spotswood Pumping Station.

“We’re also working with Westgate Biodiversity and Parks Victoria – as part of our Construction Environmental Management plan – to ensure we’re looking after the flora and fauna around the construction sites.

“Working closely together we’ve been able to ensure that our efforts are aligned and that any challenges are addressed collaboratively This partnership approach has not only helped us better understand the project’s goals but has also allowed us to find innovative solutions together, some of which resulted in securing significant financial wins for the client and project.

“As a result of our collaboration, we’re now about to expand our scope of works to include an upgrade of the North Drop Structure and being engaged for Early Contractor Engagement works to provide an optimal solution to the surrounding sewer assets that require rehabilitation.

“This approach allows Melbourne Water to maximise the efficiencies of having John Holland already mobilised onsite and tapping into the knowledge and experience of the team”

COMMUNITY ENGAGEMENT

Dr. Di Lorenzo highlighted the engagement with the local Spotswood Primary School, which selected the name ‘Lucey’ for the tunnel boring machine.

“Lucey is named after Lucey Alford, the first female Bacteriologist and the first woman employed by the Melbourne Metropolitan Board of Works (now known

“Regular collaboration meetings, open communication channels, and a shared commitment to project success have facilitated smooth coordination,” Mr Le said.

“We've teamed up with Scienceworks to inspire young minds about tunnelling works, engaged a local primary school to involve the community, and partnered with the West Gate Biodiversity Group to enrich local ecosystems.

“These collaborations go beyond construction, fostering a community-driven and environmentally conscious approach to the Hobsons Bay Main project's success”

A NET ZERO CARBON FOOTPRINT

Dr. Di Lorenzo said that Melbourne Water is aiming for net zero carbon emissions on the project, which will be achieved via a number of initiatives.

“The project has an integrated sustainable design to reduce carbon. For example, we’ve been able to reduce carbon emissions by decreasing the amount of concrete needed.

“We installed a solar energy system consisting of 250 panels and batteries that will power our construction site sheds – which traditionally would have been diesel powered. Further, this solar infrastructure can be packed up and used on other Melbourne Water projects, which is exciting from an environmental perspective”

HORIZONTAL DIRECTIONAL DRILLING (HDD)

Dr. Di Lorenzo said that electric vehicles are also being used to travel between work sites and rainwater tanks on both site compounds are reducing potable water usage.

“We’re also reusing and recycling everything we can, like soil which is being diverted away from landfill, and we even have an edible garden on site supported with composting. The environment is a major consideration for us”

Mr Martinez said that he is incredibly proud of John Holland and Melbourne Water’s commitment to sustainability.

“Building infrastructure isn’t just about concrete and steel, for us, it is about ensuring a better and greener future for generations to come.

“We have embedded sustainability into the core of this project with a commitment to achieving net zero, including solar power, sustainable concrete, alternative materials with reduced footprint, an electrical site vehicle and a comprehensive soil management program.

“We are very close to reaching carbon neutrality This will be achieved by embedding sustainability in everyday operations and all decisions made by the whole team.

“This has enabled us to reduce the footprint by approximately 30 per cent from the original design, and we are currently working with the most reputable climate consultants and Melbourne Water to secure the most reliable and traceable carbon offsets offered by the industry”

A UNIQUE AND CHALLENGING PROJECT

“It’s not every day that we tunnel under the Yarra River,” Mr Le said.

“The fact that we’re leaving behind a significant legacy that improves Melbourne’s sewerage infrastructure for generations to come is definitely worth getting out of bed for.

Mr Le said that the technical challenges associated with deep sewer construction need to be carefully considered and the complexity of working within a historically and culturally significant area makes every day interesting and enjoyable.

“This project has presented diverse challenges, each met with a strategic response. We've encountered the unexpected discovery of a culturally significant artifact during excavation, demanding careful preservation.

“Additionally, international procurement quarantine delays have required adaptive scheduling and resource management. Working around critical underground services throughout the construction period necessitated meticulous coordination and phased execution.

“These challenges highlight the complexity of the project, but through collaborative solutions and agile planning, we're able to successfully work through them”

Mr Martinez said each project delivers its own set of challenges which is part of what he loves about the industry.

“While John Holland has a history of delivering diverse infrastructure projects, this one stands out due to its highly technical nature, high-risk profile and demanding scope of works and our commitment to achieving net zero emissions,” Mr Martinez said.

“My experience has predominantly centred around the water industry. However, this project affords me the opportunity to apply my expertise within a different context and do so with a range of sustainability initiatives including solar energy, sustainable concrete and soil management.

“Along with the complexities of tunnelling under the Yarra River and coordinating with project stakeholders, these sustainable measures set this project apart, reflecting our commitment to environmental responsibility and challenging the status quo.

“This project has also delivered a number of successful social value initiatives – well beyond anything I have delivered in the past – as well as effectively achieving gender parity within the project team.”

Mr Martinez said that within a highly complex and challenging project, tunnelling works are the highest risk phase across the two-year construction.

“Challenges to date have included complex ground conditions, including shaft excavation and tunnelling through seven distinct geologies from soft silt to hard basalt, ground improvement works at our Port Melbourne site (east of the Yarra River), working within a live sewer environment and in addition, we are doing all of this within the footprint of a fully operational children’s science museum with over 500,000 visitors annually.

“Our net zero emissions target has also pushed us to find innovative ways to prioritise sustainability.

“We’ve worked to address challenges from the commencement of the project, from finding the right tunnel alignment and technical solution at tender time to secure the project, through recruiting and retaining top talent in an extremely competitive market, to managing and mitigating delays from international shipping delays in the post-COVID supply chain landscape”

A LASTING UPGRADE FOR MELBOURNE

Mr Martinez explained that once the tunnelling is completed, the John Holland team will proceed with the live connections to the existing sewers and the permanent works.

“The live connections will involve working in the existing Hobsons Bay Main Sewer under live flows, which requires very detailed and careful planning in order to make sure there are no impacts to the existing sewer network and ensure the safety of everyone involved”

Mr Martinez said that being a live asset, it’s critical to work in close collaboration with Melbourne Water Operations to ensure all their constraints and requirements are met.

“The permanent work will involve the installation of the maintenance structures which will provide Melbourne Water with access to the new asset once in operation, as well as the mechanical works (penstocks, stopboards), electrical and control scopes (power supply, instrumentation, CCTV) which will provide the asset with the required functionality to ensure safe and reliable operation for many years to come.”

Dr. Di Lorenzo said that Melbourne Water invests hundreds of millions of dollars per year into a wide range of critical infrastructure projects.

“The Hobsons Bay main sewer duplication project is a great example of the work that we are doing in this space for Melburnians.

“We’re looking towards the future and anticipating the evolving needs of a growing Melbourne.

“This project ensures our infrastructure is keeping up with future demand”

ASSESS FOR SUCCESS: GEOTECHNICAL ASSESSMENTS FOR HDD

By David Glover, Principal Geotechnical Engineer, Tonkin + Taylor

With many methods and technologies available for trenchless pipe installation, there is no one-size-fits-all solution – selecting the right technique for the right job is dependent on understanding the ground and groundwater conditions and basing your decision around that.

GAUGING THE GROUND

The best way to gain a thorough understanding of the ground conditions at any job site (or prospective job site) is to engage a geotechnical engineer prior to commencing work.

A horizontal directional drilling (HDD) or other trenchless technology contractor will be able to advise on the right tool for the right conditions. However, accurately gauging those conditions is the challenging part.

Geotechnical consultants specialise in assessing the conditions of the ground and groundwater to determine the most effective method of installation. Although there is some publicly available information on ground and groundwater conditions – such as geological maps and GIS tools like “Visualising Victoria's Groundwater” in Victoria – a geotechnical specialist will provide much greater insight. Being informed about what lies beneath the surface is crucial for determining the most suitable tools for the job.

It’s essential to note that geotechnical consultants vary in expertise, so ensure your consultant has extensive experience with trenchless technologies before hiring. Geotechnical engineers work across many fields, so it’s important to hire a consultant with experience in your specific area of interest. It’s also recommended to check that your geotechnical consultant is appropriately accredited and a registered professional engineer to ensure compliance with current regulations.

ROBUST REPORTING

Geotechnical assessment involves a combination of research and field analysis. Firstly, data will be gathered pertaining to the project area, looking at any previous reports on the ground conditions and soil composition. Then, the

geotechnical consultant will conduct fieldwork by drilling boreholes into the ground and testing samples to gain a greater understanding of what lies beneath the surface. The combination of these methodologies provides the greatest insight into the prevailing ground conditions at any job site.

GOING TO MARKET

Following the desk study and ground truthing, the geotechnical specialist will prepare a report on their findings. The report will advise on the conditions of the soil and groundwater, which will inform the drilling conditions that will likely be needed. Going to market with a ground condition report ensures you are equipped with thorough knowledge of the project requirements, and enables potential contractors to easily determine the correct tools for the job.

REDUCING RISK

There’s a saying in the industry: “You pay for a geotechnical investigation whether you want it or not”. Without a geotechnical report, contractors are bidding for jobs based on only a surface understanding of the project conditions and requirements. This often results in big cost increases and project delays down the line, as there may be undetected surprises hidden underground. Different ground composition can affect the performance and accuracy of drilling, such as unexpected surface conditions pushing the drill out of alignment. Changing course or equipment midway through a project can push contractor fees through the roof.

Understanding the ground conditions allows all parties to come to a project from an informed perspective, enabling the best decision-making for the conditions and promoting a collaborative approach to trenchless pipe installation.

MONITORING EQUIPMENT SAFEGUARDING ASSETS WHEN DISASTER STRIKES

As rising global temperatures cause a shift in weather patterns, more frequent and severe flooding poses a growing threat to critical utility infrastructure, which in turn leads to the disruption of essential services and presents a danger to the community. This is where advanced surveillance technologies come into play, offering significant benefits for flood management.

Flooding around critical infrastructure can have catastrophic consequences for utilities and the communities they serve, as well as the environment. A water treatment plant inundated by flooding, for instance, can disrupt operations and compromise water quality thus making it unsafe for consumption.

If electrical infrastructure is impacted by floods, it can result in electrical fires, equipment malfunctions and even electrocution hazards, posing a danger to public safety. Communities can be left without power, disrupting essential services and hampering emergency response. Beyond safety concerns, utilities must repair and replace flood-damaged infrastructure, with customers or taxpayers having to bear the cost.

ACCURATE FLOOD DETECTION

In the face of these challenges, keeping an extra eye on critical infrastructure is imperative. With robust and proven wireless and solar-powered surveillance and communication technology, Spectur systems are able to assist utilities even in the most challenging conditions.

In emergency situations, accurate, real-time data is essential for informing decision-making. Spectur’s high-res cameras offer utilities the ability to remotely detect flood levels and assess the extent of flooding without the use of a gauge.

Surveillance technology has also evolved significantly over time, with equipment such as advanced sensors, tags and vision-based artificial intelligence (AI) developed to the point where it can be used in disaster response.

Using a combination of cameras and AI, Spectur surveillance solutions can offer a better picture of a flood situation and can identify risks as they appear. AI can interpret images to identify risks and automatically sound an alarm, send out alerts or share information with first responders.

DISASTER MITIGATION

When critical infrastructure is damaged or destroyed by extreme weather or floods, it has a ripple effect. Deploying a surveillance system that can adequately identify risks,

function remotely and adapt to ever-changing conditions can help utilities implement preventive measures such as shutting down or isolating vulnerable components before flood waters reach critical levels. This, in turn, minimises the risk of catastrophic equipment failure, thus decreasing downtime and economic losses.

One risk of flooding is uprooted trees or floating debris, which can further damage critical assets and poses a hazard for utility workers. Autonomous surveillance can help identify fallen trees and locate debris, mitigating the challenges of post-flood recovery efforts.

STAYING CONNECTED

Dealing with climate disasters like floods requires technology that can provide accurate data while working off-the-grid. As flood waters rise, critical infrastructure can be damaged or taken out entirely, so surveillance systems must be able to operate without wired electricity or internet.

Spectur’s systems are powered by solar, which means systems remain fully operational even if electricity supply has been disconnected.

A warning system that isn’t reliant on the grid can ensure utilities are better prepared to evacuate or mitigate damage throughout a wild weather event, without a lack of information or delays in communication getting in the way.

Spectur systems can help equip utilities to better respond to natural disasters, protecting critical assets when the next disaster strikes.

SPECTUR SURVEILLANCE SYSTEM CAPTURES FLOOD WATERS AS THEY RISE OVER TIME

CUSTOMER FOCUS LEADING COLIBAN WATER FLOOD RESPONSE

In October 2022, central Victoria was hit with a major flooding event that devastated local communities. Homeowners were forced to evacuate as floodwaters damaged homes, rivers and roads. But amidst unprecedented circumstances, Coliban Water’s unwavering focus on caring for customers, and staff dedication to local communities helped it act quickly to mitigate the damage.

Coliban Water Managing Director, Damian Wells, said the water authority quickly established an incident team, which operated around the clock.

“We made a decision early on to place customer impacts at the forefront of our decision-making in an unprecedented situation.

“Our mission was to respond in a way that ensured the safety of our customers and employees.

“During the flood event we sought to protect our assets and the environment to achieve the best possible community outcomes,” Mr Wells said.

For more than 65 days, the team got on with the job and were based in the water authority’s head office in Bendigo.

“It was fantastic for staff to be clear on their mission. It wasn't about managing the flood – it was about managing the community consequences of the flood.

“Decision-making becomes quite clear when you know what you stand for,” Mr Wells said.

IN THE INCIDENT ROOM

As the incident team began to understand the gravity of the task ahead, staff members were able to draw on their expertise and experience in incident management.

“We knew this incident was going to run for a long time,” Mr Wells said.

“There was a strong focus on safety, and rostering and fatigue management were in place early.

“We knew it was going to be a marathon, not a sprint. We had to make sure the protocols we put in place worked.”

Among the assets damaged in the flood included sewer pump stations, which were submerged and had damage to their electrical controls, and part of the rural channel network which was eroded or collapsed due to flood waters.

In Rochester, flood walls installed around the town’s water treatment plant were put to the test. The plant is adjacent to the Campaspe River and the flood walls were erected following the 2011 flood. Aerial photography of the 2022 flood shows the walls successfully protecting the plant from inundation.

In Echuca and Cohuna, emergency earthworks were undertaken to protect critical infrastructure.

Mr Wells said a proactive approach meant when assets were damaged, plans were already in motion to quickly repair them.

“We had already started ordering electrical parts when the rainfall forecast came in.

“When the floodwaters went through, some of those electrical parts had arrived and it allowed us to quickly repair and recover damaged equipment and assets.”

Mr Wells said that the incident team were able to quickly establish a working rhythm.

“The emergency management environment can seem overwhelming but with good structures in place, it becomes more methodical and process-driven.”

STAYING SAFE IN THE FIELD

To ensure that staff were working as safely as possible during the flood response, Safety and Risk Manager Helen

Ellis said her team implemented several new procedures across the 65-day incident.

“With a lot more staff working around water, we held daily safety briefings that included reporting of hazards in the field.

“That allowed us to implement preventative measures,” Mrs Ellis said.

“We completed risk assessments and developed additional safe work procedures. This included the need for staff to wear life jackets when working near water, especially levees.”

The safety team also identified other risks including potholes, flooded roads, fatigue and increased mosquito and insect numbers.

“Warm weather meant that mosquito numbers increased on the ground. Bites, stings and Ross River Virus were of concern, so we arranged a vaccination program for staff.”

At times there were up to 40 staff members and contractors in the field.

“Staff tracking was vital. We didn’t rest until everyone was home safe, no matter what time of the night that was,” Mrs Ellis said.

“It was a long campaign and fatigue was a concern. Anyone who had worked seven days straight was immediately stood down until they had completed an appropriate rest break.”

Mrs Ellis said the team was proud to report no injuries or illness to staff throughout the campaign.

KEEPING A CUSTOMER FOCUS

A regular communication rhythm to provide accurate, timely and dependable information was the communication focus during the floods.

Manager of Customer Care and Support, Stewart Lines, said that remaining armed with information was a key part of the response.

“Customers just want to be informed,” Mr Lines said.

“Key information and updates were readily available thanks to the level of expertise and skills of those in the incident team.

“In addition, the team was regularly liaising with various government and response agencies, meaning the latest information was there.”

Mr Wells said the communications team issued daily updates at 10am and 2pm during this time.

“A key part of this was ensuring that we were providing the right amount of information to our communities,” Mr Wells said.

“Keeping our customers informed and anticipating their questions reassured us that we were responding appropriately.

“This also reduced the possibility of being overwhelmed with questions.”

Outside of the incident, it was business as usual for Coliban Water and the towns unaffected by floods.

“Life goes on for some people. As much as there's people out there needing help with sinkholes, there still might be a customer in Tylden for example, ringing up to pay a bill,” Mr Lines said.

Mr Wells said that the team ensured that all 49 towns in Coliban Water’s service area were catered for.

“Whilst we've got incidents and flood-affected areas, we still have to keep running the business.

“There’s still customers coming in the front door and towns that aren't flood-affected that need their usual services. There’s the continued operation of our treatment plants,” Mr Wells said.

THE FLOOD AFTERMATH

As the peak of the flood event passed, attention was shifted to medium and long-term flood recovery.

Ongoing bill relief was established for impacted customers.

Coliban Water staff assisted customers with more than 12,000 payment plans and more than 1,300 hardship payments.

“Some customers who were impacted by the floods last year are far from living back to normal,” Mr Wells said.

“To help ease the burden to flood-impacted communities, bill credits were automatically applied to eligible accounts.

“We continue to offer a range of ongoing payment support to assist customers with their bills, including concessions, flexible payment options, financial counselling and a community rebate program.”

On the ground, Coliban Water engineers got to work repairing assets, pump stations, electrical switchboards and pipelines affected by the flood.

A pipeline that supplied water to Heathcote was destroyed, as flooding had proven so strong that sections had been uncovered and washed away.

Thankfully, crews repaired the pipeline within four weeks.

REFLECTING ON THE CRISIS

Almost a year on, a continued focus remains on recovery and rebuild plans into the future.

The organisation’s efforts were recognised at the Institute of Public Administration Australia (IPAA) awards in June, when Coliban Water received the Emergency Management Award.

Mr Wells said the recognition reflected the organisation’s commitment to customers.

“During a crisis, people look to the helpers, and that’s what we were. It's not about awards, and it's not about external recognition.

“We live here, we work here, and our families live here and work here and go to school here.

“We have relatives in Rochester. We have staff in Rochester and Echuca. As members of the community, we understood the hurt these communities were experiencing.”

Mr Wells said the experience would stay with staff members for some time and remind them of the importance of their work.

“Every staff member has got their own story about their role in the floods and their investment in it,

“Every now and again, in our careers these big incidents present themselves and we are measured by how we respond.

“This award is an opportunity for us to genuinely celebrate, reflect, and say ‘We were part of something big’.

“We’ve been able to pause and reflect. The major takeaway is to continue to always put our customers at the centre of everything we do.

“That informs our decision-making and gives us clarity to consider community consequences.

“At the heart of it, we provide essential water and wastewater services, and we know the recovery of these services come into sharp focus in times of crisis,” Mr Wells said.

THROUGH THE EYES OF A ROCHESTER RESIDENT

Many towns throughout the Coliban Water region were significantly impacted by the flood crisis, most notably Rochester, where all but six houses were inundated by floodwaters.

David Keenan had the unique perspective of experiencing the floods as both a Coliban Water staff member and a Rochester community member.

He recalls significant rainfall in the weeks prior to the flood event.

“Bureau of Meteorology warnings were saying a potential flood would be 100mm higher than in 2011.

“So, at home on Friday (14 October) we set all our furniture on outdoor pavers – lifting everything up 200mm. Then it was a waiting game,” Mr Keenan said.

“When the flood arrived, it was 700mm higher than in 2011 and we had 500mm of flood water through our house.”

With waves of water coming through Rochester’s streets, Mr Keenan began fielding calls from friends and family as well as from Coliban water colleagues seeking flood information.

Mr Keenan and his family were forced to evacuate their home – only four months after completing renovations.

“It was devastating to return home and see mud and sludge all over everything.

“Cupboards were swollen and wouldn’t open, new carpet was thrown out and furniture was put on the roadside.”

Mr Keenan said the family still don’t have a clear idea of when they can return home.

“A lot of houses were so badly damaged you couldn’t enter them.”

After the initial flooding, Mr Keenan said Coliban Water staff were on the ground to repair pump stations.

“This was to enable drinking water and flushing toilets. You could see the Coliban Water utes working on a substation just up from our house,” Mr Keenan said.

“Floodwater was still in the town but the water and sewer systems were running.”

Mr Keenan spent four weeks cleaning up his property before returning to work, and reflects on the company’s response to the floods with pride.

“As a staff member, I was so impressed about what was happening in the business,” Mr Keenan said.

“To see the way the incident room works was impressive. Everyone sitting there responsible for certain tasks.

“I have spent more than 20 years in the water industry and never seen a response to crisis like Coliban Water did. They are second to none.”

COLIBAN IPAA AWARD

GETTING ENGAGEMENT RIGHT: POWERCOR MAJOR PROJECTS BUILDING TRUST

By Neve Surridge, Corporate & Customer Graduate –Reputation and Media | Corporate Affairs, Powercor Australia

For any major project, getting community engagement right is essential to a smooth delivery. Here we take a look at two major power upgrades in regional Victoria this year, and how they have shown how proactive engagement with households and businesses can help teams deliver infrastructure projects.

TRANSFORMERS AND

It’s a Sunday morning in Ballarat’s busy hospital precinct.

Normally, cars are angled along the leafy streets that surround the hospital, locals, and visitors to the city pop in and out of cafes, while others visit dozens of surrounding medical centres and allied health practices retrofitted into goldfields-era cottages throughout the area.

But not this Sunday.

The cars were gone, replaced with elevated work platforms, task trucks and pole-crane vehicles.

The foot traffic was replaced by Powercor crews working on overhead and underground powerlines and infrastructure.

The cafes were closed. The medical centres shut. Roads were closed and hundreds of homes and businesses had their power switched off for the day.

This day was just one of many where significant disruptions occurred within central Ballarat to facilitate a large-scale upgrade to the Ballarat Base Hospital. But there was no community pushback.

And that’s because residents were informed, prepared and bought-in to the work, understanding the need for the upgrade and its importance for their town.

This was a door-by-door personal approach, a genuine and authentic approach, that worked.

The result was uninterrupted work days, with crews on many occasions finishing earlier than expected, and customers that felt listened-to.

A MAJOR SHOT IN THE ARM FOR THE HOSPITAL AND COMMUNITY

The works in Ballarat earlier in 2023 were the first stage of the power upgrade required as part of Victorian Government’s $595 million redevelopment and expansion of the Ballarat Base Hospital.

hospital redevelopment, which includes a five-storey inpatient unit including 64 inpatient beds, ten intensive care beds, four new operating theatres, 12-bed maternity unit, ten-cot special care nursery and a 12-bed paediatric ward.

The project also implemented a critical back-up supply line to allow the hospital to run at full capacity even if a major outage occurs on one part of the network.

NETWORK RESILIENCE, ELECTRIFICATION, AND INDIRECT BENEFIT

Powercor Head of Major Projects and Maintenance, Marcus Olive, said the work is a testament to the business’s commitment to supporting network resilience and electrification of regional communities in Victoria.

“Large infrastructure projects such as these hospital upgrades will improve reliability for thousands of customers in these areas,” Mr Olive said.

The significant power upgrade required the largest singleworks program on the Ballarat power network in decades.

The works tripled the hospital’s power supply from 2.9MVA to 9.3MVA of capacity, enough to support the new central energy plant, a renovated emergency department, a women and paediatrics hub, a state-of-the-art theatre suite and an extra 100 inpatient and short stay beds.

With such a large project, engagement was critical. More than 100 residents and businesses were regularly informed of upcoming works, as well as directly consulted when any changes came up in the planned construction schedule.

Several residents and local business owners provided positive feedback to the project team of their ability to minimise disruption for such large-scale works. And Ballarat wasn’t alone.

In Shepparton not too long afterward, Powercor crews were again busy working to engage local businesses and residents as works took place to upgrade the Goulburn Valley Base Hospital, as part of the same state government program.

That upgrade more than doubled the hospitals power capacity from 2.4MVA to 6.5MVA, enough to power the

“Ensuring critical services are resilient and prepared to withstand a power outage is incredibly important in supporting regional areas.

“Another by-product of these upgrades is that by building new capacity, we’re creating more room on the network for new connections, such as more distributed energy resources like rooftop solar panels and residential and commercial batteries, or electric vehicle charging technology.”

DELIVERING ON TIME, WITH COMMUNITY ENGAGEMENT KEY

Earlier this year Powercor completed an even larger project, on time and ahead of state government timelines, once again supported by strong customer engagement and communications.

The Rapid Earth Fault Current Limiter (REFCL) project, a six-year upgrade of the power system across 22 zone substations and more than 17,000 kilometers of powerlines in some of the highest bushfire risk areas in western, northern and central Victoria, involved more than 3.3 million work hours, and many hundreds of planned outages for customers who were informed and updated as work progressed.

But more than that, they understood the “why”.

Helping customers understand the important “why” of this technology rollout was one of the reasons customers have been supportive of the works, despite some disruptions during construction and testing phases.

Mr Olive said the world-first bushfire mitigation device was introduced in response to a recommendation from the 2009 Victorian Bushfires Royal Commission.

“This was one of the biggest projects ever in Powercor’s network and our communities are safer for it.

“We thank the people and businesses that were affected as we installed and commissioned the devices.

“Their patience and support was instrumental in helping us to deliver this project safely for the benefit of their communities.”

A GAME CHANGER IN ELECTRICAL SAFETY:

INTEGRATED AUTOMATED RACKING DEVICES

Arc faults are a serious event where a large amount of electrical energy is explosively released causing serious burns and death of operators in the area. Additionally, they can result in significant damage to switchgear, conductors, switchboards and installations. Here we look at how new electrical safety technology can prevent disaster and protect personnel from hazardous consequences.

The most likely time for an arc fault to occur in a switchroom is during electrical and mechanical operations, such as switching, isolation and racking of circuit breakers.

It is common practice in the industry to use arc flash personal protective equipment (PPE) for operator protection during these operations, however it is ideal to isolate the operator entirely from the arc fault hazard.

CONTROLLING THE RISK

To control any risk in the workplace, the hierarchy of controls is used to determine what action will best reduce or remove the hazard at hand. In order of most to least effective, the hierarchy includes elimination, substitution, isolation, engineering controls, administrative controls and PPE.

In the case of arc faults, elimination and substitution are not possible, so instead we should take steps to reduce the overall risk through isolation, which involves personnel being separated from the energised electrical equipment and conductors. Ideally, personnel would not have to operate or perform work on the electrical equipment.

RACKING AIR CIRCUIT BREAKERS REMOTELY

The time spent in a potentially dangerous area can be minimised by utilising common accessories for switchgear, which facilitate remote operation, such as motor operators and open/close coils. There are also methods available to complete the racking of circuit breakers remotely. These allow the operator to be away from the switchroom when switching and racking operations are occurring.

NHP's TemRack iR is a fully integrated automated racking device, which enables remote racking of the Terasaki TemPower 2 AR Air Circuit Breaker (ACB) body in and out of its associated carriage. The automated racking function permits safe isolation of the ACB with zero physical interaction between personnel and the ACB, thereby reducing the risk of exposure to explosive arc fault events and high incident energy.

TemRack iR’s mechanical interlocks and safety functions integrate seamlessly with the ACB and the ACB’s functionality remains unaffected. Similarly, onsite electrical protection methodology/systems also remain unaffected.

It features integrated digital I/O for control and feedback, allowing the operator to remotely rack the ACBs in or out from outside the switchroom. Remote control can be performed via a local control station or other remote methods utilising the integrated I/O on your automation system. Where ACBs are fitted with open/closed coils, the remote operation of the ACB can also be performed as a further risk mitigation strategy.

NHP’s TemRack iR can be fitted as part of a new ACB build or retrofitted to an existing Terasaki AR ACB by NHP’s Service and Solutions Team. Minimise your risks and maximise your safety on site with NHP’s TemRack iR

DESALINATION DELIVERS HISTORIC OUTBACK WATER UPGRADES

For residents living in the South Australian outback town of Oodnadatta, a historic project by SA Water to construct a small-scale desalination plant has delivered safe and clean drinking water to their household taps for the first time.

With this plant one of five desalination facilities being delivered by SA Water in the coming years, the utility’s focus on sustainable and climate-independent water resources will be critical in building a resilient water future for years to come.

AN HISTORIC OUTBACK UPGRADE

Located more than 1,000km north of Adelaide, the township of Oodnadatta lies in the heart of South Australia’s Far North, has a population of a few more than 200 people and is home to the iconic Pink Roadhouse.

SA Water’s water supply to Oodnadatta has historically been designated as non-drinking, with residents advised in detailed yearly letters of the need to source their own drinking water using sources such as private rainwater tanks, bottled products, or water carting, with water from the taps only suitable for uses such as washing dishes or flushing toilets.

Having spent recent years investigating options to upgrade the town’s water, SA Water’s General Manager of Sustainable Infrastructure, Amanda Lewry, said that to see and taste the first flow of safe and clean drinking water was a positive milestone.

“Delivering a remote facility of this size and scope is a sizeable task, including the necessary design, procurement, community engagement, construction and testing required to ensure that our customer’s supply meets the requirements of the Safe Drinking Water Act (2011) and the Safe Drinking Water Regulations (2012),” Ms Lewry said.

“To see our customers now be able to grab a glass of water or top up their kettles directly from the tap is such a fantastic outcome, and something that will make such a difference to the daily lives of those who live and work in Oodnadatta.

“Producing up to 210,000L of clean and safe water each day, the plant uses reverse osmosis technology to treat and remove salt and other impurities commonly found in the Great Artesian Basin, where the plant’s water is sourced from.

“The end result is safe, clean drinking water piped directly to our customers, with the saline by-product resulting from the treatment process stored in a 200-metre-long evaporation basin.

“The plant was constructed inside a container in metropolitan Adelaide, before making the long journey on the back of a truck to its outback destination.

JOHN O'NEILL AND AMANDA LEWRY FROM SA WATER AT THE NEW PLANT SITE IN OODNADATTA

From maintaining hydration and protecting public health to supporting social and economic development, water is a critical part of everyday life. However for some outback towns, clean drinking water doesn’t flow freely from their taps. In an effort to provide better amenities to remote first nations communities and secure the state’s water supply, SA Water is looking to desalination.

“As well as delivering water to residents and businesses in the town, the new plant will also supply our new drinking water fountain – complete with a solar-powered chilling system – providing an easy way for locals and travelers passing through Oodnadatta to fill-up their reusable water bottles for free.

“We are proud to have delivered this important project and look forward to seeing the benefits a new drinking water supply can bring to local customers for generations to come.”

FOCUSING ON SUSTAINABILITY

Oodnadatta’s new water is part of a growing focus on desalination as a sustainable and climate independent source of drinking water production for SA Water, with the utility now operating a total of eleven desalination plants across the state – five of which service remote Aboriginal communities in the state’s Anangu Pitjantjatjara Yankunytjatjara Lands and Far West Coast.

There are also another three plants under construction and one in the planning and design stage.

The largest of the operating facilities is the Adelaide Desalination Plant, which has supplied more than 200 billion litres of water to metropolitan areas since coming online in 2011.

“With a drying climate and increasing customer demand set to reduce our available water sources over the coming decades, we understand the need to deliver secure and resilient sources of drinking water,” Ms Lewry said.

“Desalination provides us with a sustainable solution to provide water services for our customers, including in remote and regional areas of South Australia.”

SA Water is in the process of completing construction on two similar containerised reverse osmosis plants at Marla, also in the state’s Far North, and Maree in the Far North-East, with the first supply of safe, clean drinking water for local customers in these communities set to start flowing for the first time within 2023–24.

“We know the positive social and economic impact having access to drinking water can provide, and we’re excited to see all three of our new outback treatment plants up-andrunning over the coming months,” Ms Lewry said.

“We also continue to make progress on the delivery of larger desalination plants for the Eyre Peninsula and Kangaroo Island, which, when constructed, will be a significant boost in providing a resilient and sustainable water supply to thousands of our customers into the future.”

BUSTING MYTHS IN THE HDD INDUSTRY

In this article we explore some of the most frequently asked questions and debunk common myths about horizontal directional drilling (HDD). We’ll discuss the benefits it provides when assessed against other pipe installation methods, and focus on the environmental upside, flexibility of design and how the technology supports construction in congested, urban, industrial and sensitive environments.

DO I NEED TO DIG EXIT AND ENTRY SHAFTS TO UNDERTAKE HDD?

A: No. HDD has entry and exit sites; however, it doesn’t require deep shafts or large pits. While construction equipment is required within these sites, this equipment remains on the surface, and is often bunded and contained within a relatively small footprint that can minimise environmental impacts. For large diameter HDD, the onsite operational equipment generally includes:

• Entry pit generally 3m x 3m x 1m

• Power units and generators

• Water and mud slurry pumps

• Mud mixing tanks and recyclers

• Drill pipe racks and transport

• The rig itself and support equipment such as:

• Vacuum truck

• Small excavator

• Tool storage & setdown

• Site amenities

• Exit pit generally 3m x 2m x 1m

• Drill rod storage & set-down

• Rollers and pipeline handling equipment

• Pipe racks

• Room for Product pipe string during pullback

IS HDD INSTALLATION LIMITED BY DEPTH LIKE OTHER INSTALLATION METHODS?

A: No, with HDD installation you can easily reach depths of more than 50m without the hassle and cost of digging and shoring trenches or using complicated support structures to support deep shafts. Going deeper can reduce the risk of hydrofracturing (frac-out), which is when drilling fluid or mud comprising non-toxic bentonite, soil and water escapes from the bore hole to the surface. With more coverage the likelihood of fluid escaping to the surface is significantly reduced, further reducing environmental impact. The actual

depth limit depends on the project geometry such as entry and exit locations, bore design length and ground conditions, but it’s the perfect method of pipeline installation when you want to keep the landscape intact and go under existing assets rather than through or over them.

WHAT’S THE DIFFERENCE BETWEEN HDD AND MICROTUNNELLING?

A: Microtunnelling is pit launched while HDD is delivered from the surface. Microtunnelling tends to be 30–50 per cent more expensive than HDD due to the cost of the jacking pipe, constructing the launch pits, the number of pits, and the depths of those pits.

Accuracy is another factor often discussed when comparing the two methods. Microtunneling machines are very precise, boring to within 10mm of a target. However, it is slower and involves more setup than HDD. HDD has an average accuracy of within 10cm to a target point, better for larger-scale projects that don’t require millimetre precision. And using state of the art guidance technology, skilled drillers now deliver gravity sewer grades of 1:150 using HDPE. HDD also offers the advantage of speed and flexibility and can get in and out with minimal setup while still maintaining the high degree of accuracy required by asset owners. HDD can drill both vertical and horizontal radiuses to avoid obstacles, which is only achievable with very large diameter microtunnelling and tunnel boring machines.

The pit-to-pit distance limitations for each microtunneling machine are not a problem for HDD, with maxi rigs now capable of drilling large diameter bores for more than 1km without surfacing.

HOW LONG DOES A TYPICAL HDD PIPE INSTALLATION TAKE?

A: HDD installation time varies depending on the length, size and diameter of the pipeline. For very large pipes, this can take weeks or months. However, HDD is much faster than other alternatives.

WHAT PIPE INSTALLATION TECHNIQUE SHOULD I CHOOSE?

A: Choosing a pipe installation technique is really a case of the right tool for the right job. HDD is a great mix between microtunneling and tunnel boring and is also often a lower cost option when factoring in all the elements and costs involved with pipe installation. HDD also offers many environmental benefits that make it ideal if environmental constraints are a factor.
