Real sustainability goals for SUEZ

The water industry faces sustainability, affordability, and infrastructure development challenges today. SUEZ Australia and New Zealand is here to support utilities and councils as they become more sustainable.

“WE ARE TARGETING practical actions, which benefit the planet and future generations,” said Eric Garcin, Innovation and Performance General Manager at SUEZ Australia and New Zealand (ANZ).

The SUEZ Group unveiled its sustainable development goals for 2027 and beyond earlier this year. As part of that, the company has 24 commitments and 43 key performance indicators (KPIs) that

“Having discrete KPIs around energy and emission impacts is important for us to move forward,” said Garcin. “We are focusing on our sustainability roadmap and activities as well as assessing plans, actions, and measurements. It all starts from properly measuring the impacts of our activities.”

Garcin has been with SUEZ for decades, starting from his original work experience position at the

SUEZ’s sustainability roadmap aims to rejuvenate the Australian landscape, fostering a thriving ecosystem

understanding of the technologies SUEZ uses around the world.

“Utilities and wastewater treatment plants worldwide face a range of challenges, each with different circumstances and solutions,” he said. “SUEZ has to consider the economic and regulatory drivers that will impact each project. Australia, for example, has a unique environment with a population spread out over large distances and a regulatory system changing across multiple jurisdictions.

Built into structure

The roadmap’s success hinges on SUEZ’s ability to structure its actions around a strong common ambition. The company can forge partnerships and collaborations that transcend geographical boundaries to achieve actionable outcomes by aligning its initiatives with this collective vision. Through these alliances, SUEZ seeks to maximise the impact of its sustainable practices, contributing to a more sustainable future on a global scale.

“We have three main pillars in our sustainability roadmap,” said Garcin. “Climate is the first one.

Nature is the second one – nature in the sense of biodiversity. The third is social or community. It looks at what we would have qualified under corporate social responsibility for communities.”

One of SUEZ’s biggest challenges is navigating the fine line between affordability and outcomes. Garcin

and the teams in SUEZ are seeking the right tools and approach to deliver the right solutions in an affordable way. Despite this test, everyone across SUEZ is looking to reduce the impact of its clients’ activities on the environment.

“For us, being carbon neutral is not the goal,” said Garcin. “There are plenty of companies out there that are approaching carbon neutrality, but they are achieving it through offsets and certificates. They are not making real efforts to reduce their carbon footprint. SUEZ wants to work in a way that contributes to carbon neutrality while providing a positive impact. That means switching to green sources of energy, for example. It’s not about spending money on offsets and certificates. Hopefully, this action will be a positive step forward for moving into a true carbon-neutral society and economy.”

Green infrastructure

SUEZ has been at the forefront of green infrastructure in Australia for several years. One example is the Boneo wastewater treatment plant, one of the most advanced treatment plants in the world.

“SUEZ has a range of new technologies targeting carbon neutrality within the plant,” said Garcin. “By working on methods to minimise the negative externalities, SUEZ is at the cutting-edge of technology for the circular economy.

The goal is to reduce the plant’s energy use while finding value from the products generated from the treatment process.”

Boneo has advanced technology for wastewater treatment and biosolids.

Garcin pointed to the work being done on sidestream anaerobic ammonium oxidation (anammox) that will reduce the plant’s energy footprint.

Another aspect of green infrastructure is the location of wastewater treatment plants. Garcin spoke about the different situations facing Australia and Europe.

“Australia has a lower population density than most cities in Europe. As a result, most of the wastewater

of cities and suburban areas,” he said. “However, that’s not the case in Europe. European cities tend to be denser, so wastewater treatment plants can be found throughout the city or even the CBD. As a result, SUEZ must spend more time and effort ensuring that the wastewater treatment plants are well-integrated into the landscape.”

When integrating a wastewater treatment plant into an urban environment, SUEZ must consider reduced emissions, odour, and noise. Another method involves incorporating vegetation into the surroundings to expand its natural appearance. In some cases, the plants have been installed underground.

Recovering by-products

“The third driver SUEZ considers when it comes to green infrastructure would be the circular economy,” he said. “We need to look at all the waste and consider them as by-products. By-products have value, so we want to find how to return those valuable resources to the economy. Ideally, we can generate value both economically and environmentally.”

Garcin pointed to the recovery of phosphorus that is taking place around Australia. With imported phosphorus doubling in price over the past 18 months, a new approach was needed.

“SUEZ is running successful trials of the technology in Australia that it

has deployed in Europe,” said Garcin. “The trials show that providing recycled phosphorus will be more economical than mining the product. Right now, the quantities extracted from wastewater treatment plants are insufficient for Australia’s fertiliser industry. However, it’s one way to reduce the volume imported and the associated emissions associated with importation.”

Smart metering and IoT

SUEZ has embraced smart metering, helping water authorities revolutionise monitoring and managing resources. The company empowers clients to gain real-time insights into their consumption patterns by deploying digital water solutions. This enables informed decisions and fosters a culture of responsible resource usage; a fundamental component of its sustainability outcomes.

“The main driver of smart metering technologies is to support reductions in consumption,” he said. “It helps utilities and end-users by reducing

leaks and non-revenue water. It also helps utilities to get a better view of the network by picking up leaks. Giving consumers access to their consumption data in a near real-time fashion is driving changes in consumption.”

Garcin pointed to the apps created for Singapore’s Public Utilities Board (PUB) with the support of SUEZ. Gamification is adding game mechanics into non-game environments to engage with consumers, employees, and partners to inspire, collaborate, share, and interact.

The objective of WaterGoWhere was to give insights into households’ water use patterns, habits, and motivations behind water-saving. This would help and reward users for improving water usage.

It is driven by the “Vision for a Smart Nation where people are empowered by technology to improve living” from Singapore’s Smart Nation program. The WaterGoWhere platform uses smart metering to measure the water consumed,

also known as advanced metering infrastructure. This infrastructure analysing the data provides personalised challenges and tries to change the user’s behaviour to help preserve the region’s water resources.

“We use apps like WaterGoWhere for residents to measure their water consumption,” said Garcin. “They can compare their water use to their neighbours, block, street, or even suburb. There are different ways to drive consumer behaviour, but adapting to the different culture and needs of the utilities are key. Finding a way to leverage the data is vital, and this is a virtuous approach. It can be applied to commercial, industrial and residential customers.”

Sustainable Development Roadmap at SUEZ

SUEZ ANZ is looking at multiple ways to expand its sustainability development roadmap. The company is dedicated to providing essential water and wastewater services while protecting the

environment. The common ambition guides its actions while avoiding some “traditional” methods of assessing progress.

“We’re not looking at using market mechanisms,” said Garcin. “When we look at our emissions KPIs, we focus on more precise objectives like using green energy. SUEZ also has KPIs around energy production within its wastewater treatment and waste-to-energy plants. While it’s not a big focus in Australia, it is in Europe and South Africa. It means that we need to find a balance between the energy the treatment plants produce and use. It’s why SUEZ is looking at the net benefit of emissions.”

By increasing the portion of green electricity outside of certificates and market mechanisms, SUEZ works across multiple aspects within the three pillars of its Sustainability Development Roadmap.

“What SUEZ does when it comes to climate is clear. However, what SUEZ does under the nature pillar

is not as obvious as people may first consider. We have objectives and precise measurements for the renaturalisation of soil within our sites, both new and existing. There’s also an objective around artificialised environments. That means developing a natural environment that allows water to permeate the ground. Concrete needs to be removed, and roads need to be permeable,” said Garcin.

Other objectives under the nature pillar involve light pollution and fugitive emissions. Some facilities managed by SUEZ must deal with scope one emissions, primarily methane and nitrous oxide. Specific actions to reduce these emissions can also be found in the waste industry.

“When it comes to the nature pillar at the Victorian Desalination Plant, SUEZ has significant commitments to maintain and expand the reserve’s ecology around the site,” he said.

“It’s an extensive site that is open to the public, so SUEZ has significant objectives for planting native

trees and vegetation while also maintaining the grounds. The idea is to encourage more biodiversity through the site.

When it comes to looking after people, SUEZ requires its facilities to engage with the local communities. That can incorporate business and work opportunities for the local community and increased proportions of local procurement. Other objectives consider training for diversity and inclusion in its workforce.

“It’s about trying to find real actions that bring real benefits. SUEZ is developing solutions and making them available to all its clients and all utilities, after it has tried and validated them. We want to be satisfied in year one, but we still want to be satisfied in year 20. When these solutions have demonstrated value, we are happy to present them to other clients.”

YOUNG PROFESSIONALS Wei Wei and Lan Wu

UTS researchers making waves

The Centre for Technology in Water and Wastewater (CTWW) at the University of Technology Sydney (UTS) is

“I HAVE ALWAYS cared about environmental problems since childhood and have had a continuous passion for waste and wastewater treatment,” said CTWW researcher Lan Wu.

CTWW, under the leadership of Professor Long Nghiem, has grown from strength to strength since its establishment. It seeks to develop water and wastewater technologies that can be applied in residential, commercial, and industrial environments. The current research themes include:

• Wastewater treatment and re-use technologies

• Water supply and alternative water sources

• Water resource management and catchment modelling

• New materials and membrane processes

The research focuses on the development of innovative technologies. These new technologies should deliver abundant recycled, desalinated, and harvested stormwater supplies. The new technology is aimed at regenerating and modernising existing water infrastructure in a cost-effective, safe, and reliable way without needing to rebuild from the ground up.

Wastewater researchers

The focus on wastewater treatment and reuse technologies has highlighted the work of one research team. The team, led by Professor Bing-Jie (Bruce) Ni, has spent significant time working to reduce nitrous oxides and methane emissions. It has also developed

the first fundamental understanding of the biotoxicity of microplastics and nanoplastics. Another area of research is developing technology to gain renewable liquid bioenergy from sewage sludge. The team

Researchers such as PhD candidate Wu and ARC Decra Fellow and Lecturer Wei Wei are working to improve the situation for the world. Both of them are originally from mainland China and have a deep appreciation for improving how the world deals with wastewater.

“Waste and wastewater treatment is a serious issue in China, especially after policies were implemented to improve people’s living quality. This was achieved by becoming a global hub for manufacturing,” said Wu. Wu is working on her PhD under Dr Wei. She is focusing on the reclamation of nitrous oxides for a new source of renewable energy and converting organic wastes to liquid bioenergy. Wei’s research is looking at ways to reduce sewage sludge and do something with it.

“I have been working in environmental biotechnology, wastewater/sludge treatment and environmental toxicology,” she said. “My research focuses on developing and applying innovative and sustainable techniques to achieve sewage sludge reduction. I want to transform waste from a troublesome pollutant to a valuable resource with maximised energy recovery. I’m also looking at how to mitigate the adverse influences of emerging contaminants (e.g., microplastics, nanoplastics) on energy recovery in wastewater/ sludge treatment systems.”

Reclaiming liquid bioenergy from sludge

According to Wei, Australia’s energy consumption is growing by about two per cent per year. While that does not sound like much, much of this growth is sourced from natural, non-renewable sources.

“Wastewater treatment plants (WWTPs) in Australia annually produce around 360,000 dry tons

of carbon-rich sewage sludge,” said Wei. “It typically represents a substantial, but largely untapped renewable energy resource. Treatment facilities that re-direct sewage sludge from waste to renewable energy resources can bring strong economic, social and environmental benefits to Australia.” Her group has developed an innovative technology to gain renewable and high-value liquid bioenergy (medium chain fatty acids) from sewage sludge. The technology allows for easy collection, storage, and transportation. It can be applied in existing anaerobic sludge fermentation infrastructure, as well as to develop new applications in a range of industries for addressing Australia’s escalating energy demands.

Nitrous oxide emissions

One fugitive emission that many people do not think about is the group of nitrous oxides (NOx). Nitrous oxides represent about 10 per cent of all emissions from WWTPs. Partial or complete denitrification removes nitrogen from sewage and municipal wastewater. New technologies can reduce the amount of carbon and energy

required for denitrification.

“The idea to look at this area came from Professor Ni,” said Wu. “We wanted to investigate ways to use nitrous oxide emitted from WWTPs as a renewable source of energy. There was a lot of focus on the role of nitrogen monoxide (NO) in producing nitrous oxide. It’s a challenging pathway, but we looked at how coal is used to power big chunks of Australia. Once we have a lot of nitrous oxide, it can be burnt with methane. It burns with more energy than methane being burned with oxygen. That makes it significantly better for the wastewater industry.”

This technology, once further developed, provides opportunities for energy self-reliance across the country. It also eliminates the need to use ammonia for the process, which is better for the Australian fertiliser industry.

“I have used the fermentation process. It’s an established technique for WWTPs, and we can collect methane emissions. By combining methane with nitrous oxide for combustion, we can generate more energy than existing technologies,” she said.

Biochar to fight microplastics

Microplastics, and nanoplastics, have become an issue for most countries and the environment. The environmental risks associated with micro- and nanoplastics are continuing to grow. While there has been plenty of discussion about the impact microplastics have on humans and animals, there has been less research done on the impact of microplastics on microorganisms.

“Our studies found microplastics induced toxicity toward anaerobic microorganisms during wastewater treatment,” said Wei. “This biotoxicity decreases wastewater treatment efficiency. Considering the negative impacts of these microplastics, it is important to find effective ways to reduce the direct contact between microplastics and microorganisms in wastewater. If we can do that, we can alleviate and mitigate more of the negative impacts of microplastics.”

To do this, Wei’s research group looked at biochar. It’s a promising carbon absorbent that comes from the pyrolysis process.

“Biochar has excellent pore structures and functional oxygencontaining functional groups. There

are other mineral elements as part of biochar,” she said. “Sludge, as the byproduct of wastewater treatment plants, could be utilised as the initial feedstock of biochar formation. This would not only lessen the costs of wastewater treatment plants but also transform waste into functional materials. We have demonstrated that biochar is capable of mitigating the inhibition of microplastics on wastewater treatment efficiency.”

What’s next?

Wu is working towards her PhD, focusing on renewable energy from sludge. Once she gets her doctorate, Wu wants to optimise the bioenergy outputs from food waste.

“There’s enormous potential for the industry to work with our research,” said Wu. “There has been considerable interest in

Australia in producing mediumchain fatty acids and long-chain alcohols. It would improve the monetary value of organic wastes and facilitate the establishment of a bio-based economy within Australia. Food waste is a carbonrich and abundantly produced waste across Australia, which can also be utilised as a promising substrate for bioenergy production.”

Wei is working with industry partners to ensure that her research goes somewhere.

“The sewage sludge-to-energy work is ongoing. I need to further optimise the sludge management and wastewater treatment plant operations. Ideally, we will find a method to efficiently recover liquid bioenergy from wastewater and reduce our carbon footprint eventually towards net zero emissions from wastewater

The research has the potential to turn wastewater into highly valuable products.

Golden fields for women like Sammy

Samantha “Sammy” Jung was one of three speakers at the OzWater’23 Women in Water Panel. As the Engineering Manager of Goldenfields Water, working in a regional environment, she presents unique insights into the industry.

“I WAS FORTUNATE to experience different cultures and their relationship with water. Nepal was an important eye-opener for me. People were swimming in waterways that had religious significance, but they were getting sick when doing so. They didn’t have access to a safe water supply.”

Samantha “Sammy” Jung, the Engineering Manager of Goldenfields Water, is based in the Riverina town of Temora, north of Wagga Wagga. After graduating from university, Jung started her career in local government. After a brief stint in the private sector, she landed a job at Goldenfields Water and has gone from strength to strength.

water industry,” Jung said. “That

overseas travel helped open my eyes even further. I was lucky that the opportunities that opened to me helped me fall into the sector early in my career.”

Who is Goldenfields Water? Goldenfields Water is responsible for water supply functions within the local government areas of Bland, Coolamon, Junee, Temora, and parts of Cootamundra-Gundagai, Hilltops and Narrandera. It supplies drinking water to approximately 46,000 customers across 22,526 sq km in parts of NSW’s South West Slopes and Riverina regions.

“Goldenfields Water has been fantastic for my career,” Jung said.

on the engineering manager role. It was both a blessing and a curse because I’m not sure I was entirely ready to step up. However, I didn’t want to miss my opportunity, so I gave it a shot.”

Jung believes that she is now in a different learning environment and is benefitting from it. Goldenfields Water is all about achieving excellence through innovation, regional efficiency, technical excellence, and customer service by recruiting for success and fostering an atmosphere of continuous improvement and support.

“Our management team is 50 per cent female, and so are our engineering officers. It wasn’t a conscious achievement. We’re fortunate that our organisation attracts enough diversity that the equality occurred organically,” said Jung. “Goldenfields Water has been an excellent supporter of me and my career. They helped me find a mentor, whom I found in former Australian Water Association President and highly experienced woman in water, Carmel Krogh. The water industry tends to be smaller and more close-knit than other industries. Carmel was happy to take me on as a mentee, as she wanted to help others in the industry.”

What else is Jung doing?

Jung is a young mother and has found both water and local government to be highly supportive of her needs. Both industries understand the needs of mothers, and she appreciates this.

“The local government sector is typically very thoughtful and supportive of mothers. They ensure that flexible workloads and flexible arrangements are available to staff. We can access many benefits regarding different arrangements

around kids at Goldenfields Water. They understand that if your kids are sick, things can be adjusted,” she said.

When she took the job as engineering manager, she thought she would be managing engineering. Jung was slightly surprised that the role was more centred around managing the people and supporting them to achieve the organisation’s goals.

“It’s a fantastic role where I get to be involved in so many projects without being involved at an intense level,” said Jung. “My role is helping my team to look to the future. We want to take the right steps to consider our community’s future needs. We are looking at what we need to do to plan now for the future and how to capture and use all the asset information. As a business unit, we need to be able to provide the most cost-effective way of servicing our community.”

“Women are playing, and will continue to play, a critical role in the industry. We are crossing the stepping stones for women’s rights and equality within the industry, and I hope it’s helping other groups to follow.”

Probiotic pipe cleaner

Probiotics have been central to improving human health over many decades. But can they be used to make pipes cleaner?

“ACCORDING TO THE World Health Organisation, waterborne bacterial infections account for about 80 per cent of all illnesses in developing countries. The bacteria tend to thrive in moist environments such as water systems. We tend to find them as biofilms that are hard to remove from pipes, leading to bacterial infection.”

Cici Zhou, a former Queensland Academy for Health Sciences student and now an undergraduate at Peking University in Beijing, was a finalist in the 2022 Australian Stockholm Junior Water Prize.

Zhou’s paper was titled “Probiotic Water Treatment: The Effect of Probiotic Lactobacillus Strains on The Inhibition and Degradation of E. Coli Biofilms as a Novel Method for Waterborne Pathogenesis Control.”

an alternative to antibiotics, when asked about why she was interested

in using probiotics in her research.

“Looking at probiotics came from considering what other than antibiotics I can use to fight these pathogenic bacteria,” she said.

“Antibiotic resistance is a huge problem right now. I wanted to look at other approaches to the problem, and probiotics have become more popular recently.”

What is her research about?

Zhou’s project addressed the topic of bacterial biofilms in waterways, as they cause water contamination. Biofilms contribute to the pathogenesis and development of

laboratory.

“I got into this area when I first learned about helicobacter pylori. It’s a ubiquitous bacteria, and one of my family members got sick from a helicobacter pylori infection. I started researching and discovered that about half the world’s population had been infected by it at some point,” she said.

In her reading and research, Zhou found that many scientists and researchers examining this field are still determining how bacteria spread between people.

Pipetting probiotics into samples was the base for Zhou’s research.

“There are a lot of data points that link the bacteria to water contamination. I started investigating how bacteria causes water contamination in almost any country. This is where I learned about biofilms and the issues surrounding them,” said Zhou.

Biofilms are a collective of one or more types of microorganisms that can grow on many different surfaces.

Cici Zhou in the

Biofilm formation begins when freefloating microorganisms and bacteria encounter an appropriate surface and begin to put down roots. The question now is; how do biofilms colonise water systems?

“One of the main things I want to do is work out how probiotics could target specific bacteria,” said Zhou. “To do that, I need to learn more about the different types of bacteria that colonise water systems. I then have to select probiotics that will target those bacteria effectively.”

The search for the right probiotic

Finding the right probiotic is key. Zhou explained that some probiotics could promote biofilms within waterways. It’s why she wants to analyse the samples first. It would be vital to understanding how the biofilms react to probiotics.

“One of the most important parts of my research will be to ensure that biofilms do not simply recolonise the inside of the pipes,” Zhou said. “They’ve already gone through the cycle of becoming a biofilm after being in their planktonic phase. That’s where the cells are freely floating in the moist environment. If we do not eradicate them properly and leave the bacteria alive, they can go and create another biofilm elsewhere in the system.”

This is why simply cutting the biofilms away would be counterproductive –many cells would still be alive. That allows them to create another biofilm in another location.

“That’s why I was mainly focusing on the antimicrobial properties of probiotics,” she said. “I’m hoping that probiotics kill the cells as well as the free-floating cells to prevent the creation of another biofilm.”

The future of her research Zhou wants to focus on biotechnology as a future career

path, particularly one incorporating artificial intelligence. Its increasing use in society has inspired her to look at how she can integrate technology into biology and healthcare. She knows that her research needs more work.

“I know that my research needs more refining,” said Zhou. “More work needs to be done to develop

right place, it could flow anywhere within the pipe network,” she said. As part of her technological thinking, Zhou pointed out that water networks can be long and complex. This adds an additional level of concern for getting the probiotics to the correct location.

For climate, communities, and our kids

Having been in business for 86 years, Interflow has proven it knows a thing or two about longevity. According to Richard McCarthy, Interflow’s Executive General Manager — Southern Region, that requires an all-encompassing sustainability strategy.

“AS A BUSINESS, we are constantly thinking about the needs of the next generation,” said Richard McCarthy, Interflow’s Executive General Manager — Southern Region.

“That’s the way it has always been. This organisation has proven it will be around for generations to come.”

As one of the longest-serving private businesses in Australia, Interflow has always appreciated the necessity of shaping the business – its practices, processes, and purpose – around the needs and expectations of current and future generations.

Sometimes that forward-thinking has to do with innovation. Often it has to do with professionalism and skills. And it is always related to good commercial decision-making. But today, there’s another vital ingredient in the recipe for business success – ESG, or environmental,

social and governance. For many team members, this is personal.

“I’ve got three kids, all at university age and older. Your own kids make you realise it’s not just about your time here. It’s about what you’re leaving behind,” McCarthy said.

It’s also a beautiful engineering challenge for McCarthy around how to do the work Interflow does economically and environmentally pragmatically.

“How do we navigate our way through our work so it all makes sense?” he said.

“Of course, it’s about doing things differently. But we all know that when we work sustainably, it just feels right.”

Interflow’s customers also have expectations of the contractors they bring on board. But the company doesn’t want that to be the driver of its core ESG priorities.

Looking

“We’re building an ESG strategy because it makes sense in every way as a business and community member,” McCarthy said. “We’re doing it because it’s the right thing for us to do.”

Creating Interflow’s ESG strategy

As outlined in its sustainability framework, Interflow is developing an ESG strategy around three core areas.

“Our ESG strategy is looking at what we can add next,” McCarthy said. “What can we do well that will make a real difference to the business, our customers and our community?”

Fast fact

Interflow’s ESG strategy revolves around these three areas: Our environment: encompassing climate change and environmental management. Our communities: including health and safety, and diversity and inclusion. Our business: incorporating sustainable growth and supply chain.

McCarthy pointed out that there are things around environment management that Interflow wants to perfect.

“So much of what we do is out in the environment, and when we get it right, we’re building a better environment,” he said. “There’s a focus on community engagement because we are in people’s back gardens, national parks, and roads. We’ve got to get that part right, too.”

Interflow’s partners are vital to the plan’s success

A critical factor in creating the Interflow ESG strategy, which will

“It can be perceived that these are outside our control, but they’re not outside our influence,” McCarthy

with them to influence what they do. That’s one of the exciting things about the net-zero challenge –nobody can do it in isolation. It’s all about how we work with the organisations we work for and the organisations that work with us.”

FOCUS Sustainability

ESG is much more than net zero

It’s always important to remember that net zero is just one part of ESG. Another focus area of the ESG strategy is inclusion and diversity. The overwhelming evidence around the phenomenal power and performance of a workforce with diverse perspectives, backgrounds, experiences, and ways of thinking drives this.

“We’re creating an allencompassing ESG framework for three reasons,” McCarthy said. “One is that it’s so clearly aligned to Interflow’s purpose. We’re not delivering on our purpose if we don’t do it. The second is that it just makes good business sense. Sustainability will save the business money, open new opportunities, and enhance our reputation. Finally, it just feels right.

When you work for organisations that are only about making a profit, it just doesn’t feel right.”

Enhancing the existing ESG work

“One of the greatest realisations is how much Interflow is already doing in terms of sustainability. As soon as we put a framework in place that allowed us to measure

our sustainability performance, we recognised that we were doing quite well. The power then becomes about enhancing this across the business,” he said.

Success is, to a large extent, about the little things people do daily. It ranges from the crew leader who switches off the generator whenever possible, to the job scheduler who organises teams to attend local jobs, to the buyer who chooses to purchase from a supplier with a low embedded-carbon product.

Some solutions are as simple as sequencing work to ensure Interflow teams are not zig-zagging back and forth across cities to various jobs. Instead, they should be attending projects in a more logical, linear fashion. Interflow team members can further reduce emissions by taking a more straightforward path.

“We’re taking quite a methodical approach to our path to net zero,” McCarthy said.

“We don’t know exactly what it looks like yet, but we do know we’ve got to meet the ambition of our customers. And we know we want to do it in a way that doesn’t leave us running around like an under-seven soccer

team, chasing the next thing. We want to do this as a co-ordinated unit.”

Interflow’s people expect nothing less

A clear ESG strategy is not negotiable for the Interflow team. McCarthy said people want to work for an organisation that aligns with their values and beliefs. They also expect honesty – which is one of Interflow’s core values.

“We’re constantly developing our ESG strategy,” he said. “But it’s also important that we’re open and honest about what we can do and where we don’t yet have the answers. The last thing we want is any form of greenwashing.

“Our people want their employer to work with purpose. Our community expects and requires our care and attention in everything we do. And as an organisation, we have powerful expectations around how we work. That’s why we’re putting so much effort into it now.”

Reducing pipe waste through Pipeback

health and safety of its employees, customers, and communities. It is continually looking for ways to apply sustainability principles in everything it does.

AS PART OF this commitment, Iplex is working towards enabling a circular economy within the pipe industry. It has established its stewardship program, Pipeback, to help minimise clean unwanted pipe offcuts going to landfills and maximise the sustainable use of pipes.

Iplex has established Pipe and Packing Recycling Centres within Australia’s manufacturing and

distribution sites. It can accept polyvinyl chloride (PVC), Iplex polyethylene (PE), and AS/NZ

4130-compliant PE pipe offcuts and fittings. Other recyclable products include timber frames and scallops. In providing this service, Iplex aims to minimise waste-to-landfill practices at the early stages of pipe installation. Thus, supporting Australia’s plight on plastic waste reduction and transition towards a circular economy.

PVC pipes is fundamental to the Pipeback program.

PVC used in pipe production are made to last and are made from 100 per cent recyclable materials. They are also made to some of the world’s most stringent standards, making them resourceful if they can be returned for recycling.

When discussing Pipeback, the goto person is Elaina Lobendahn. She is the National Sustainability Manager at Iplex, using her engineering and systems industry experience to help Pipeback succeed and grow.

How does Pipeback work?

It all starts with one good business decision to avoid adding unwanted clean pipe offcuts to landfills. Customers are key to this process. “Pipeback allows all sectors, including the plumbing, construction, and water industry, to return clean, unwanted PVC and Iplex PE pipe offcuts,” she said. “These offcuts are usually generated on job sites at the point of installation and can be returned to any of our participating recycling centres around Australia. We currently have seven sites across New South Wales, Queensland, Victoria, and South Australia.”

Pipeback provides guidance criteria on the Iplex website to assist customers in returning their

offcuts correctly. A simple Pipeback form completed on the website allows anyone to engage with the program at different locations. Pipeback provides accessibility and a customer-friendly service that is easy and simple to engage with. This has immensely contributed to the success of the program.

“Iplex also offers more collaborative partnerships with its long-term customers. The goal is to develop long-term solutions that see projects expand on sustainability requirements and outcomes. These partnerships go beyond the drop-off service to include education, design optimisation, and supporting their sustainability goals,” Lobendahn said.

“Returns are then processed and incorporated into remanufacturing selective pipe products under strict product standards. Recovering clean unwanted pipe offcuts is just the beginning. There is a lot more we can do. A new way of thinking worldwide regarding plastic production will drive more reuse and recovery for remanufacture.”

Support from industry

The Pipeback program is continuing to develop and grow, with the Iplex team focused on optimising the returns process and service offerings.

“A lot of our customers and participants are taken aback by the fact it is a voluntary program,” said Lobendahn. “The Plastics Industry Pipe Association of Australia (PIPA) are massive supporters of the stewardship of plastic pipes.”

Iplex is collaborating with PIPA and other industry participants on another recycling program, the Queensland Government-supported

Construction Plastics Recycling Program, to better understand plastic pipe waste flows.

A growing focus for Pipeback is on having conversations early enough to make positive changes.

“Without concerted industry efforts, the volumes of pipe waste to landfill will continue to grow,” Lobendahn said.

“Iplex, as a manufacturer and supplier of pipe products with specialist product knowledge and in-house technical expertise, will be an important voice in the broader industry conversations around recovery and recycling, plastic production, water challenges and infrastructure resilience. We aren’t just looking at recycling pipes. Iplex is looking at a wide range of sustainability programs and partnerships.”

Future growth of Pipeback

Iplex believes that there are multiple growth paths for Pipeback moving forward.

“We must continue to think big and work collaboratively,” she said. Pipeback will grow organically with industry. It is currently focused on collecting clean unwanted pipe offcuts produced during installation.

The next big challenge for Pipeback will be the recovery and processing of pipes reaching the end of service

life that has been used for decades.

“It will require a collaborative effort by industry and certainly government support. It will require champions and partnerships that are crossfunctional between different industries.”

Water security & sustainability through smart metering

Iota is part of a consortium scaling out one of Australia’s largest fleets of smart water meters for the Toowoomba Regional Council in Queensland.

HOW CAN COUNCILS implement smart water sustainability programs and actively engage consumers?

By providing customers with more granular understanding of their water usage, they can better manage the consumption of this vital resource.

Earlier this year, a consortium led by Optus and including water innovation industry leaders Iota and GreenBe, was awarded the contract by the Toowoomba Regional Council (TRC) to scale out the successful pilot program to all 68,000 properties in Toowoomba.

Staged implementation of smart water meters

Over the next three years, Iota will supply more than 68,000 ultrasonic Cura digital meters that will deliver

daily water consumption usage data and early detection of leaks for residents in the Toowoomba region. Iota’s Enterprise IoT platformLentic will manage the smart meter fleet and incoming data so that the council can action leak alarms, use the consumption data for billing and share it with residents.

“The smart water meter technology will give council accurate data and improve early detection of leaks and breaks,” TRC Water and Waste Committee Chair Councillor Rebecca Vonhoff said. On average about 12 per cent of residents experienced a leak on their property. The largest leaks were referred to the Rates and Revenues Section of council for immediate follow-up and investigation. “This suggested substantial improvements

could be gained by giving approval for the smart water meters program to be rolled out more broadly,” Vonhoff said.

“This is a significant shift from how we read water meters,” Vonhoff said. With this data we will be able to identify future leaks, which will help us save valuable water.”

Larger commercial meters will be retrofitted with an NB-IoT data logger from Iota, to enable water use and anomaly detection for business customers.

Iota supporting sustainability and smart water projects

“Toowoomba Regional Council is always looking and thinking about ways to improve things,” Vonhoff said. “I think the decision behind the smart water meters is to find water savings. We went through the proof-of-concept phase. Then there was a decision by the council when we looked at the results of that phase and decided to roll out the full program.”

Toowoomba Regional Council is rolling out one of the largest fleets of smart water meters in Australia.

Iota’s digital water solutions are unique as they are developed and tested at scale within its parent company South East Water. South East Water is a leader in digital metering for water with the largest rollout of meters in Australia and a pioneer in the integration of smart sensors into digital meters. The Lentic platform and Iota’s expertise were key differentiators for the choice to select the consortium.

“Lentic is best-in-breed globally. It is an enterprise IoT platform designed from the ground up for water, including all of the proven use cases,” Iota’s CEO Daniel Sullivan said.

Sullivan espouses smart and sustainable tech

“Lentic has been designed to help a modern water utility to scale with a focus on functionality that automates many of the activities associated with digital metering such as billing, meter exchange and leak notification. It’s been designed by a water utility for a water utility. It does not require customisation.

“Toowoomba Regional Council was impressed with what Lentic could do for their requirements around digital metering, as well as how it can help the council transition into a digital utility as they embrace IoT and data. Seeing a water utility think beyond AMI metering towards being a digital utility is really encouraging,” said Sullivan.

He said the IoT platform has been integrated with the council’s various corporate systems, including Billing, Asset Management and Customer Relationship Management (CRM), and expects it to benefit the council and the regional community in ways that go beyond water metering.

“It’s challenging to make large and long-lasting investment decisions if you don’t have sufficient data. IoT connects you to your assets and

with your customers so that you can understand and influence their behaviour. It provides utilities and customers with the tools and information to ensure we preserve the most precious natural resource,” Sullivan said.

Residents to play an active role in sustainability and water bill reduction

With the smart meter rollout, residents can set and monitor water usage targets through a web portal and app. Consortium partner GreenBe will use data from Lentic to display consumption dashboards for customers and notifications when water usage goes beyond a certain threshold. This helps residents take more ownership of the role they can play within the Toowoomba region.

“The meters will provide close to real-time readings,” said Vonhoff.

“Residents will be able to check their usage. They will be able to review their data which will make it easier to see which activities around the property are causing high water consumption. This will help to reduce the chance of residents

The smart water meter technology will give council accurate data and improve early detection of leaks.

get their bill. If properties have an underground leak, the meters will also help with early detection.”

Smart water underpins a sustainable future

Once completed, the smart meters and vast volume of data generated will enable the council to control the water network more efficiently, allowing them to allocate resources better, save precious water and provide cost savings to council and residents. In future the data can be harnessed by the council for other use cases such as smart cities.

For now, the transition from trial to a 68,000 smart meter rollout shows TRC is taking bold steps to secure its water and improve its residents’ customer experience. The decision to scale is also a demonstration of confidence in the consortium. Iota will continue to work collaboratively with the council and partners to help TRC transition to a digital utility and secure water for its community.

Mareeba drives sustainability with smart metering

Mareeba Shire Council calls itself a growing, confident, and sustainable shire. Mareeba has a diverse array of landscapes, from the wet tropics to the dry savannah outback. That creates an acute understanding of needing to properly manage water resources, along with other sustainability goals.

water metering systems. Mareeba needed to improve its meter reading process. External contractors were using antiquated meter reading equipment, which tended to be problematic in terms of accuracy and data presentation,” said Hamill.

“The process of manually reading the meters was also resource intensive and provided very little data to help manage the network on a day-to-day basis.”

“As a council, we were looking at hiring more staff to look after our meter reading or to head down the smart water metering path. At the time, there were not many providers The only company that had any runs on the board in this field was Taggle Systems. Mackay Regional Council, Taggle’s founding customer, was very open about sharing their knowledge and experience with us.”

and a successful smart water metering program, Mareeba has made a difference for its residents and achieved sustainability goals.

Morris Hamill, the Water and Waste Manager at Mareeba Shire Council, has been involved in the water and wastewater industry for more than 35 years and was an early adopter of smart water metering as he saw the sustainability benefits the solution could provide.

“By implementing smart water meters, we have supported more responsible and sustainable water usage across our region. Water treatment and distribution is an energy-intensive process, so by reducing wasted water, we are also saving on power and the

water unnecessarily. Reduced fuel consumption from quarterly meter reads and regular special reads also deliver towards our sustainability goals within council.”

Mareeba’s smart water journey Hamill explains the beginning of Mareeba’s smart water journey “In 2007, Mareeba Shire Council was amalgamated with the shires of Atherton, Eacham, and Herberton to form Tablelands Regional Council. However, we sought to de-amalgamate, and Mareeba Shire Council was re-established in 2014, allowing us to independently manage our water resources again. The desire to pursue our own destiny saw us reach out to Taggle to improve our

Mareeba being in Far North Queensland meant Mackay was relatively close by. Hamill and other council representatives met with Mackay Regional Council, with visits both ways. “This allowed us to understand how the technology worked by seeing a live and working system, what benefits were being realised and what challenges might arise.” Mackay had reduced its water demand significantly by implementing the Taggle solution, which deferred the need to build a new water treatment plant and ensure the sustainability of its water supplies.

Hamill also met with representatives from Taggle, who came to council offices to ensure it understood the full end-to-end solution and the steps to roll out the system.

Implementation

“Taggle offered to run a trial for us, but council felt that it had learned a lot from what Mackay was doing and was confident to go ahead,” he

telemetry devices have helped capture vital data.

at the proposals, Taggle had the only reasonable one.

“We decided to do the full rollout across our population of about 22,000 people in the Mareeba area in 2015 and smaller areas in 2016. There were no integrated smart water meters back then, so we changed a large portion of aged and worn meters for new ones, then added the Taggle telemetry devices, which sent the meter readings back to us every hour.”

“Taggle worked with us to train local contractors to properly install the transmitters to the water meters and sync the data back to the meter management software, Aqualus Water, which back then was known as MiWater,” said Hamill. “Taggle was really proactive in working with the contractors to ensure that everything was done correctly. They were doing verifications and other checks so data would be transmitted and received properly.”

Benefits to the community and council

Many of the old meters were no longer working correctly, so changing the meters made a huge difference instantly in reducing nonrevenue water.

While this isn’t a direct benefit of the smart metering data, the project

for end users.

This is where negativity can sometimes come up from residents, and councils have been wary of the feedback when it comes to installing smart metering systems.

However, Hamill said that the community was on board early on.

“The community really embraced what we were doing, and that feedback was also going to the elected council members,” he said.

substantial leaks.”

In the first week, Mareeba found 284 leaks across the network. Most were relatively small, but the volume of water lost quickly adds up when viewed as a whole. Some, however, were quite significant and wasted a lot of water.

“We found one resident who had a leak of about 1500 litres an hour! His block was on the sand, so he couldn’t see how much water was being lost. Once we showed him a graph and a table of what was happening, he was astonished,” said Hamill.

Sustainable smart meters

“It is leaks like these that greatly impact our sustainability goals and finding them quickly helps us with demand management. It ensures we can deliver water to our community over the long-term responsibly and sustainably.”

“When we look at the long-term goals, the council is very focused on sustainability,” said Hamill. “Because we now have the water data, it helps us form policies around the water networks and how it integrates into society. It goes hand-in-hand with our governance policies and sustainability outlook.”

ESG, sustainability practices benefit from smart meters

Satisfying environmental, social, and corporate governance (ESG) is essential for the water industry.

SMART WATER METERING

and monitoring are crucial to sustainability and ESG practices. They are essential for water utilities and even more so for commercial and industrial property managers,” said Guenter Hauber Davidson, Managing Director of WaterGroup, one of Australia’s largest water savings companies.

WaterGroup’s services and products help save water and money. They leverage the Internet of Things (IoT), innovation, and sustainable solutions. Water suppliers, local councils, and large water users in the industrial, commercial, retail, and institutional sectors can benefit from its expertise, design models, and engineering solutions.

These entities can reduce water usage and costs by implementing effective water metering and monitoring systems. “That also helps improve their ESG performance, and

it contributes to a more sustainable future,” Hauber-Davidson said.

WaterGroup’s smart water meter and monitoring solutions enable water utilities and property managers to track their water usage accurately. End-users can identify areas where water is being wasted or used inefficiently. This data can then be used to take action to reduce water usage and improve efficiency.

Leaks can be identified and repaired quickly. Water-intensive processes can be optimised to reduce water use – and cost.

“Woolworths is a great example of achieving environmental sustainability and operational outputs through smart water metering. They have dramatically reduced time, cost, and risks by addressing abnormal water usage across their stores. Last year, they saved 139,000kL through our services,” said Hauber-Davidson.

How else is WaterGroup encouraging sustainability?

Effective water metering and monitoring can improve ESG performance, attract socially responsible investors, and enhance property managers’ ESG rating. ESG is a framework used by investors to evaluate the sustainability and social impact of a company. ESG performance is becoming increasingly important to consumers, who are more likely to support companies prioritising sustainability and social responsibility.

Water metering and monitoring can help water utilities and property managers comply with regulatory requirements. Many jurisdictions have regulations to limit water usage and prevent water waste. Water utilities and property managers can ensure their companies comply with these regulations and avoid potential fines and penalties by implementing effective water metering and monitoring systems.

Real-time data on water usage promotes water conservation and raises awareness about sustainable water usage. Using this data, water utilities and property managers

can encourage individuals and organisations to take action to reduce their water usage. For example, residents and tenants can be incentivised to reduce their water usage by providing real-time feedback on their actions to save water.

Smart water metering solution WaterGroup’s solutions, including smart water metering, an Active Water Analysis, Risk and Efficiency (AWARE) service, water efficiency, and leak detection, have saved customers money and water year on year.

The smart water metering solution provides near real-time insights into billing abnormalities and leaks. WaterGroup’s integrated NB-IoT smart water metering solution is instant switch on, can reach hardto-access areas, is low cost and easy to deploy.

“Our UtiliOS platform and NBIoT integration enable smart water meters and loggers to deliver actionable data. To get the maximum ROI, clients need a dedicated resource or a monitoring service like WaterGroup’s AWARE to turn their smart metering data into insights, actions, and solutions,” said Hauber-Davidson.

“With a proven track record, our AWARE service typically reduces a client’s water usage by 10-15, and initially up to 25 per cent with a 2-3year payback,“ he added.

WaterGroup’s smart water metering solution is flexible, costeffective, modern, intelligent, and customer friendly. Providing a solution that integrates with existing legacy systems eliminates several cost centres. At the same time, WaterGroup’s solution allows for data transmission to relevant parties, whether it is to staff, tenants, and residents.

WaterGroup also sells a newgeneration acoustic IoT data logger

called SmartEAR. Designed for water networks, customers can reduce leakage rates, minimise water losses and improve operating costs. The data is securely transmitted quickly and reliably by offering both LTE-M and NB-IoT connectivity technology. SmartEAR is designed to be simple to install with its SmartEAR-GO app.

“One of the main obstacles for water utilities are installation and maintenance costs. Water network leak monitoring systems can be expensive to install and require ongoing maintenance to ensure their accuracy and reliability. This can make it difficult for water utilities to justify the investment, particularly where the cost of water is low or not sufficiently valued,” said Hauber-Davidson.

“With the SmartEAR, water utilities will reduce costs by no longer requiring two or even three different

devices to detect a leak and transmit data to the cloud. The SmartEAR does it all in one. Labour costs are also noticeably reduced as these smart acoustic loggers can be installed in six easy steps with the SmartEAR-GO app in less than 60 seconds.

“To keep up with the increasing pressure on our water supplies due to the effect of climate change, we cannot stand still. We must continue to transform how we manage our water, especially now with renewed expectations of another, possibly even more severe, El Nino coming and the ensuing drought conditions. Now is the ideal time to add water monitoring solutions and reporting into ESG and sustainability policies to future proof assets.”

The Captis smart water meter from Kallipr has been the preferred device for WaterGroup.

Cultivating sustainable solutions

High-quality analysis

Seddon and Cress use a range of tools to understand the fundamentals of a particular industry or business sector. At that point, the goal is to realise that specific sector’s drivers and economics.

“We want to know things like the top costs and biggest drivers of change and challenge in that specific industry,” she said. “We come armed with that background understanding, and then we look at the business and run a benchmarking assessment. This helps us to know where our client is relative to other companies in the same sector, domestically or internationally.”

Understanding how mature their client is regarding sustainability, climate change, or in meeting ESG requirements provides a lot of value to the client, in the eyes of Seddon. Understanding where the organisation is relative to carbon emission reductions or any other aspect of their targets. It also provides the client with knowledge of how they compare to their peers worldwide.

“WE DON’T DO greenwashing, and we don’t do lip service. We don’t go in and say, ‘Oh, look, you’re doing all these wonderful things already. You don’t need to do very much more.’ We do gather all the information and use it as a baseline to improve upon. As a consultancy, we show organisations what they can accomplish by adopting a shift in business strategy, and Cress works with them to make it achievable.”

That’s Cress Consulting principal Julia Seddon. Under her leadership, Cress Consulting has the expertise to help businesses identify pathways to a more sustainable, secure, decarbonised future. It

believes organisations need to understand the risks of climate change to create a more resilient, efficient, and sustainable future.

Cress Consulting works to help businesses and organisations design strategies to reduce risk and increase self-reliance.

“We are consistent and deliver tailored solutions to each customer,” said Seddon. “We commit to spending time with our clients and customers to understand their business. We want to create a fitfor-purpose piece of work that is the right size for the organisation while presenting a challenge to work towards a more sustainable and secure future.”

“By providing this high-level analysis, we can help our clients understand if they are in a good position or need to do a lot of work. It’s imperative to see what good looks like and then identify the steps to get there,” said Seddon.

Sustainable procurement key area

One of the most important areas for any enterprise is sustainable procurement. By working with every link in the supply chain, organisations can work to improve sustainability outcomes at every level.

“The idea of sustainable procurement is for everyone to play their role. Organisations need to influence their supply chain to become more sustainable whether that’s reducing emissions, getting to net zero,

identifying modern slavery or other sustainability risks,” said Seddon.

The life cycle needs to be examined, along with the key suppliers. Seddon focuses on the conversations with suppliers and partners around going on the sustainability journey together.

“It’s essential that the conversations are had,” she said. “Organisations need to talk with their suppliers and partners to find out their positions on the relevant sustainable issue, whether it’s energy, emissions, water, or something else.”

For those organisations with a procurement function, it’s fairly

straightforward to pivot towards a more sustainable focus. Such a transition makes sustainability part of the rules of engagement.

“It’s an opportunity to have the supply chain demonstrate that they are on an emissions reduction pathway, or a path that adequately addresses sustainability risks. This would then flow through other parts of the supply chain and could impact consumer use of the product,” said Seddon.

Stakeholder engagement

Any organisation will have numerous stakeholders inside and outside

the corporate structure. Effectively engaging stakeholders in the broader sustainability analysis and strategy creation can be challenging for organisations. However, working out how to get them on the sustainability journey can be easier than some might suggest.

“When looking at the value or supply chain, organisations need to think about suppliers and service providers. It’s not limited to physical products but could be web hosts, data centres, or any other service provider. Often, organisations are very clear about the contractual arrangements but have less idea

Cress Consulting has been at the cutting edge of sustainability strategy development for decades.

FOCUS Sustainability

of what drives the other company towards its goals. One party may not be aware of the other company’s targets or ethos around sustainability,” Seddon said.

Seddon believes looking at contractual discussions through a sustainability lens can lead to better relationships with suppliers and service providers. It can lead to stronger partnerships around shared goals. It is about having a different conversation with existing stakeholders and recognising that sustainability is important to them.

“It’s important to have as full a relationship as possible with those key suppliers and service providers,” said Seddon. “Sustainability can often be a good way to do that. It’s not a discussion about commercial terms; it’s about working with commercial stakeholders, customers, employees,

regulators, unions, and the local community. Some might even consider the media as a stakeholder as well. A comprehensive stakeholder map can lead to significant benefits for an organisation.”

Organisational change comes with strategy

Seddon pointed out that organisational change is critical to implementing a sustainability strategy.

“I recently met with a client that Cress has been working with for two or three years,” she said. “Our work helped them build internal capacity around sustainability. They are kicking goals and making great progress on their own. From a standing start, we now have mature conversations around sustainability issues, metrics, and targets. They also

highlight the flow-on benefit for their staff. The company found that the staff are reacting positively by talking about sustainability and what they are doing.”

The organisation employs many young people for whom sustainability is crucial for retention. Seddon pointed out that being able to tell people that they are making a difference at work is an indicator of sustainability as a critical HR tool.

“When doing our analysis, we found that staff went home at the end of the day to tell their friends and families that they are making a difference. The sustainability strategy impacts the family at a personal level and business performance level.”

Helping water utilities to net zero

Xylem has had a long commitment to supporting communities, protecting the environment and sustainability.

“THE NEED TO solve water and resource challenges has never been greater. This past year, natural disasters and extreme weather has become more frequent, more costly, and more harmful to communities across the globe. Every day, about two billion people do not have access to safe drinking water, and nearly 40 per cent of the world’s population faces water scarcity.”

That’s why Xylem President and CEO Patrick Decker is continually focused on the importance of sustainability to its operations. As an organisation, Xylem fundamentally understands looking after and properly managing water.

There are different challenges and

for each country. Xylem Australia & New Zealand (ANZ) is teaming up with water utilities, local councils, and industrial water users to help them as they achieve net zero.

What do water utilities need to report on?

All water utilities participate annually in National Greenhouse Gas Energy Reporting (NGER), an annual static snapshot of emissions. However, the process needs more granularity and accuracy to meet enhanced legislative reporting requirements and societal demands for sustainability.

The race to net zero for any utility focuses on de-carbonising the urban water cycle and its supply chain

Avensor is just one solution offered by Xylem to support its

covers all emissions (including Scope 1, 2 & 3). Scope 1 and 2 emissions are those owned or controlled by a company or the water business, while Scope 3 emissions occur from sources not owned or controlled by it.

What emissions are essential to reduce for water utilities to achieve net zero?

The community primarily focuses on CO2 emissions related to energy consumption. However, fugitive-type CH4 (methane) and N2O (nitrous oxide) emissions from wastewater treatment plants are far more potent regarding global warming potential. They should be monitored and measured more effectively through wastewater treatment processes. Buying green or renewable energy, or having energy recovery facilities as a capability, does not change the fact that methane and nitrous oxide are being emitted. These gases need to be tracked and calculated to truly reduce overall emissions. However, more accurate real-time monitoring and modelling of the overall wastewater process is vital.

How can water utilities be confident they are reducing emissions?

A water utility has a complex supply chain comprising many people, assets, and components. Many of these assets are ageing, underground, or both. Some organisations cannot effectively measure, gather, and consolidate enough operational data to properly baseline emissions, risking their net zero initiatives

The insights from data are invalulable when it comes to managing water resources.

being viewed as “greenwashing.” Corporate regulatory reporting is already a difficult and timeconsuming task for utilities. Adding emissions policy and legislation as a safeguard mechanism will add further complexity to regulatory measurement and reporting.

The challenge for water utilities is pulling the relevant informationoperational-engineering technology (IT-OT-ET) data together, collected from all business units, into a coherent view. Managing this data and developing an effective and efficient measurement system is vital for water utilities to achieve net zero.

Is it all doom and gloom on the road to net zero?

Xylem remains optimistic about its ability to support water utilities worldwide in plotting a course to net zero. Many of Xylem’s products and solutions already measure, gather, and consolidate data to optimise operation and maintenance domains.

The next horizon is how to harness that data. Xylem Vue, powered by the GoAigua platform, brings together disparate network data to positively impact a water utility’s net zero ambitions.

How can Xylem support a water utility in achieving its net zero ambitions?

Delivering net zero outcomes require water utilities to go on a digital transformation journey.

Xylem has a range of holistic solution capabilities to support water utilities in this transformation process. Considering a Smart

Water Engine provides operational performance benchmarking in the context of net zero targets and objectives.

The water utility can then identify opportunities to reduce emissions and prioritise the appropriate activities and investments to impact net zero targets the most. This Smart Water Engine can be confidently achieved via a water industry-proven engine such as Xylem Vue powered by GoAigua.

Understanding treatment processes is vital to water utilities. Xylem can provide AI studies to water utilities for their water and wastewater treatment plants that will help them identify areas where they can improve the performance and resilience of plant processes and positively impact energy consumption.

These process improvements are all modelled using Xylem’s Treatment System Optimisation (TSO) solution in real-time and further contribute to a water utility’s pathway and supporting reporting requirements to achieve net zero.

Combining emissions monitoring and systems maintenance

Coupling emissions monitoring with maintenance optimisation provides a powerful approach to reducing fugitive emissions. Xylem is developing partnerships with global experts in emission monitoring hardware to address this challenge. Optimising reactive maintenance works and implementing a predictive maintenance strategy reduces energy consumption and field staff time. Xylem’s solutions, such as Avensor for alarm routing and

SAM PRO for performance and reliability optimisation, support these strategies.

The third phase optimises the workforce workflows and manages a larger installed base of multiple assets with multiple applications. It effectively reduces costs and operational staff time in the field, which can be enabled by Xylem’s Digital Maintenance (XDM) solution.

The final phase to reach the summit in this process is to bring multiple software applications, remote management/control of assets and various systems to a “single point of truth” platform. This single platform will improve real-time decision support to visualise insights and opportunities to reduce emissions more efficiently. This can be enabled by Xylem’s Aquatalk platform, which has multiple applications from Xylem available and integrated for use.

Having new information in a timely manner can support a water utility in reducing its emissions.

FOCUS Water Tanks

What sensors are best for water tanks?

foam absorbed the measurement substance. It reduces the magnitude of the echo reflected to the sensor. Unique and proprietary software combats this issue head-on. Built-in DATEM analysis helps the ultrasonic transducer zone in and focus on the true echo, giving accurate and reliable foam level readings.

How radar technology works in many situations

Radar technology emits microwaves towards the measurement substance. Foamy surfaces cause these waves to be scattered – equally reducing the magnitude of the echo returned to the sensor.

Foamy applications are seen throughout the wastewater network, including wet wells, aeration tanks, and some settlement tanks. Water companies across the globe now have a choice of technology to choose from to measure these applications, with both technologies producing similar results.

sump levels, tank levels, stormwater overflows, and open waterways. These technologies range from non-contacting ultrasonic technology to hydrostatic pressure and, more recently, non-contacting radar technology.

Ultrasonic-level measurement methods have traditionally prevailed due to their relatively low cost and non-contacting nature. Unlike hydrostatic pressure measurement, they are not subject to wear and tear from contacting the substance being measured, therefore requiring less maintenance.

Ultrasonic sensors have many uses

Advancements in ultrasonic technology mean there are few applications where this technology

focus on the ‘true’ echo profile, ignoring any competing noise from cluttered or crowded wet wells, foam interference, or atmospheric conditions.

Previously, radar technology had the reputation of being more expensive than ultrasonic technology. This was never justified in its performance. In recent years, radar technology has seen investment. It is now used more widely throughout the wastewater network.

One myth of the wastewater network is that you need a radarlevel sensor if you have a foamy surface. Wrong. Neither technology can see through the foam to the true surface. Traditionally, with ultrasonic sensors, the sound waves shot down, and the

environments, including foamy surfaces.

A specific application where radar would be preferred over ultrasonic would be the storage of chemicals. Chemicals are used throughout the global wastewater network for sewerage, water treatment, and cleaning. These chemicals are likely to emit fumes or vapours that influence ultrasonic soundwaves. This application is where radar could provide the answer, as it can see through plastic tanks there is often no need to come close to the measurement substance. Its frequency-modulated continuous wave is unaffected by fumes or vapours, allowing for accurate and reliable measurement, even on harsh chemicals.

Why do we need sensors for water tanks?

A water tank sensor is a handy device designed to help users

gauge water levels and maintain ethical standards or avoid wastage due to overflowing. It also helps control the water level in pipelines, power stations and water management systems.

Some companies prefer to offer submersible-level sensors. The tank level sensor transmits signals that help analyse the precise water levels. The level transmitter is safe to use as it is equipped with a wire for high protection level, which also facilitates sensor measurement for long distances.

Both technologies can work in tandem

To conclude, no matter what the application throughout the wastewater network, ultrasonic technology is likely to be able to

As easy as child’s play

VEGA has consistently come out with a range of instruments to support different market segments. By understanding those market needs, its new technology represents a systematic development of concepts and products.

THE INTRODUCTION OF the plics family more than 10 years ago has seen VEGA develop a vision for simple, standardised measurement of level and pressure into reality. The VEGABAR 80 series further develops the concept and the products. The clear structure of the new instrument series ensures easy selection when looking for the right instrument for a particular application. The new handling

allows fast, simple, reliable setup and commissioning. The integrated diagnostics system now makes fast maintenance and servicing possible. With the VEGABAR 80 series, all potential applications can be covered with three process pressure transmitters. The all-rounder VEGABAR 82 features a ceramic measuring cell, covering 80 per cent of all applications. VEGABAR 83 has a metallic measuring cell,

applications. The classic VEGABAR 81 with a chemical seal is used when high temperature and/or chemical resistance is required.

Ceramic versus metallic

In recent years, advancements have been made in developing metallic and ceramic measuring cells. The ceramic measuring cell CERTEC has experienced the biggest technological leaps, making it VEGA’s core technology.

While only a few suppliers offer ceramic-capacitive cells, VEGA produces them in-house. Approximately 80 per cent of all units sold operate with ceramic sensors, and both technologies can be used in most applications.

Thermal shock and moisture susceptibility are common weaknesses of ceramic measuring cells. However, through further development of CERTEC, these issues have been reduced or eliminated altogether. VEGABAR 82 is equipped with temperature shock compensation. A patent has been applied for this worldwide innovation. When sudden temperature changes occur, it can take several minutes before sensors with ceramic measuring cells deliver reliable readings again. Users often did not know that a sensor was experiencing a temperature shock and transmitting incorrect values.

The new temperature shock compensation ensures that sensors with ceramic measuring cells deliver reliable readings even during sudden temperature changes. Users will get accurate measurement data, as the fast temperature changes no longer affect the pressure measurement. This is achieved by incorporating a second sensor in the glass joint behind the ceramic diaphragm, compensating for thermal shock.

The VEGABAR82 is designed for most

measurements, eliminating the need for a separate temperature sensor in many applications. NAMUR has already praised this feature.

Moisture sensitivity has also been reduced in the new instrument generation. VEGA has implemented a measurement and a reference capacitor, covering the surface of the measuring cell with a thin layer of glass. This prevents the ingression of dielectric fluid from affecting the pressure reading. The instrument computes the change in capacitance and balances it for an accurate measuring result.

VEGABAR 82 has a measuring range of 25 mbar without electronic turndown. The measuring range has also increased from 60 to 100 bar, expanding application limits.

CERTEC is the only ceramic measuring cell that allows absolute front-flush mounting, making it suitable for abrasive applications. It is used in the paper industry in more than 40,000 measuring points. Additionally, the sensor self-cleans in the flowing medium, preventing build-up.

Safe, reliable operation

data, adhering to the guidelines of IEC 61508. It can be implemented up to SIL2 in single-channel systems and up to SIL3 in homogeneously redundant systems.

Electronic differential pressure

The VEGABAR 80 family allows users to combine any two instruments into an electronic differential pressure system. By connecting a VEGABAR 82 with another sensor, customers benefit from simplified selection, adjustment, operation, and stocking.

The electronic differential pressure system eliminates the need for insulated oil-filled capillary tubes and chemical seal assemblies. This makes

Motor protection made easy with moneo wizard

Imagine having Gandalf protect your industrial motors. It would be a formidable force to reckon with. According to Freddie Coertze, the ifm moneo Data Science Toolbox has its own wizard. It can provide just that type of protection.

“A UNIQUE ASPECT of moneo is that this wizard can help users determine the vibration limits of their motor and predict failure well in advance,” said Coertze, the National IoT Business Development Manager for ifm Australia. “This allows enough time to act. It’s a great way for an industrial business of any size to start implementing a predictive maintenance plan. It avoids the fuss and complexity associated with this process. You’re starting just with the motor monitoring.”

Unlike other condition monitoring solutions, moneo has been designed for ease of use. It is a self-service IIoT platform where the hardware, software, and smarts – predictive formulas created by machine learning – come in one package. The advanced vibration analysis (AVA) wizard is a tool that comes

Easy setup

“It’s straightforward to set up,” said Coertze. “The wizard tool will talk you through the steps, so you can do everything yourself without needing an IT or analytics expert. It’s a matter of connecting your sensor, dragging and dropping that into the moneo dashboard before selecting the motor configuration. Moneo has a data science tool that will create baselines for you regarding the acceptable limits of motor vibration for that configuration.”

Users can then start seeing the vibration levels of their motor installation on the dashboard. The set limits suggested by moneo appear as red and yellow dots. They indicate if the motor is running outside of its boundaries.

“If vibration levels exceed

goes into alarm,” explains Coertze.

“It’s the difference between a warning for imminent failure and early predictive notification. Essentially, this wizard gives you time to fix motor issues before they become bigger problems. You need to predict to protect, and this wizard helps you do that.”

Moneo is designed to be simple for users and expand with changing requirements.

“You can extend on this form of motor protection by adding a device that provides a more intensive vibration and into other aspects of predictive maintenance as well,” said Coertze. “But if we think about businesses just wanting a starting point, this is a great way to begin. You might have an asset such as a conveyor where if it breaks down due to a motor failure, the whole production of a facility might come to a halt. This tool will inform you in advance if the motor has issues such as misalignment or being out of specification. This allows you to fix it before any such event occurs.”

People Summit reaches new heights

experience to talk about workplace culture, gender bias, the role of trust, and the values of doing the right thing in authentic leadership.

“IN GENERAL, LEADERSHIP defines the culture, whether it is the smallest organisation – like organising a school fair – to the largest organisation listed on the ASX,” said Julia Banks.

People are the water sector’s most important asset. Without them, the Victorian water industry would be unable to deliver world-class services to enhance the liveability of our communities.

The summit sought to showcase safety, culture and leadership and put a spotlight on all things people. Some key areas of focus included managing psychosocial impacts on staff, the water sector safety pledge, driving cultural change and leaders of the future.

was welcomed to the stage. He’s also the CEO and Chief Optimism Officer at the Centre for Optimism and a Director of Yarra Valley Water. Referencing the recent passing of Tina Turner, Perton spoke about how the people at the summit are “Simply The Best.” He encouraged the attendees to enjoy the day. Perton also set three challenges for the attendees. The first was to meet someone new and keep in touch. The second was to laugh a lot. The third was to aim to be at the best people and culture summit ever.

Keynote speaker Julia Banks Banks was the keynote speaker. She

Banks opened her presentation with the trailer for the 2022 film, She Said She spoke about how the Weinstein Company failed on all three counts of safety, culture, and leadership, compared to what it looks like on the outside. Banks pointed out that while very few organisations are perfect, she likes to think that most organisations are on the positive end of the scale. She also acknowledged that the existence of microcultures can cause problems.

Power is part of the structure of inequality. The way people use power over someone else was a key point of Bank’s presentation.

“Every CEO has two types of power, personal and positional,” she said. “Everyone in this room has personal and positional power. What differentiates the good from the bad and the ugly is how they use their personal and positional power. What makes a difference in positive and negative workplace culture is how power is used by the leaders of organisations.”

In looking back at her time in Federal Parliament, Banks reflected on the period in which she announced that she would no longer contest the seat of Chisholm in Melbourne’s eastern suburbs. She spoke about the bullying and negative workplace culture she experienced in the lead into the 2019 federal election.

“Often when good women call out or are subjected to bad behaviour, the reprisals, backlash, and commentary portray them as the bad ones: the liar, the troublemaker, the emotionally unstable or weak, or someone who should be silenced. To those who say politics is not for the faint-hearted and that women

have to toughen up, I say this: the hallmark characteristics of the Australian woman… are resilience and a strong, authentic, independent spirit,” said Banks on the floor of the House of Representatives on 27 November 2018.

Her discussion of workplace coercive control described the behaviour as always taking someone’s voice. Banks referred to an incident in a workplace where an emerging female leader’s potential promotion could have been stymied by one person who felt threatened by that woman’s ambition. She spoke of the CEO using their personal and positional power to stop the irrelevant conversation and focus on the essential aspects of the woman’s career path.

“You do not have to meet the stereotype of a strong leader,” she said. “You can be your own kind of leader.”

Panel discussions

There were several panel discussions throughout the day following Banks’ keynote speech. The first looked at managing psychosocial impacts in the workplace. The panellists were

Frances Anderson from the Victorian Government Solicitors, Rebecca Hanley from Coliban Water, and Danielle Nigro from Davidson.

The discussion focused on the mental health of employees within an organisation. They included topics such as how health and safety laws relate to psychological health, building strategies for change management, properly communicating crises, and holding a mirror to yourself as a leader for better interventions.

The panel concluded that leaders need to understand the risks of not addressing mental health by developing a positive workplace

Sarah Cumming from Gippsland Water, Maree Lang from Greater Western Water, Jane Brown from Salesforce and Christine Nixon

AO, APM from Leadership Victoria, discussed the topic. The key focus points for the panel were the idea of what the future leaders of the water sector might look like, what skills they will need to have, and how they need to work inside and outside of their organisations. The idea of “We don’t do that here,” as presented by Christine Nixon, was one message that reverberated through the crowd.

Individual speakers

Andrew Jeffers from Wannon Water spoke on behalf of the VicWater Safety Executive Group. He discussed its approach to safety and wellbeing across the Victorian water sector. “Don’t let perfection get in the way of progress,” he said. “What gets measured gets managed, but the question is what should be measure?”

Jeffers was followed by Deb Fankhauser from Lower Murray Water, who discussed inclusion and diversity. She spoke about what diversity and inclusion mean for the water sector, where the industry has come from and where it is going. Her closing polls provided a deep insight into what the Victorian water sector needs to do in areas such as neurodiversity. Participants also pushed for more work to be done on assessing organisational leaders on inclusion and diversity.

The panel on Managing Psychosocial Impacts in the Workplace

Plastic pipes play a critical role in society’s life. They deliver essential services from urban to rural environments. But how are they in line with the broader sustainability goals of society?

IT’S HARD TO comprehend the vast network of plastic pipelines installed and in operation in Australia and worldwide. Most are buried and remain in service for more than 100 years. Today’s plastic pipeline systems are still in their first life cycle.

“Plastic pipe systems align with all three key principles to a circular economy – designing out waste and pollution; keeping products and material in use and regenerating natural systems. You can see why they are the preferred choice to

replace and upgrade other pipe materials,” said Executive General Manager of the Plastics Industry Pipe Association (PIPA), Cindy Bray.

The sustainability story Not all plastics are the same. Too often, plastic pipe systems are mistakenly put in the same category as short-lived, single-use plastics.

delivering

reflects the growing pressure to reduce reliance on short-lived, single-use products and the drive to increase post-consumer and preconsume plastic recycling levels.

“As an industry that converts large volumes of virgin material into long-life products that deliver our essential everyday services to homes and communities, it’s important that we educate across a wide range of audiences on the role plastic pipes systems play,” Bray said. “This includes how they are different to other plastic products and why the manufacture of virgin material is critical for people and the planet. Our sustainability story provides these insights and context supported with data and science.”

Plastic pipes are engineered products designed to last

The plastic material used to manufacture pipes is engineered to be robust, reliable, and recyclable. They are intended and designed to last a long time, more than 100 years. The engineered polymers used are stable materials. These properties are suitable for a product such as pipes requiring long life expectancy.

“Some people may be surprised

Production plants for the manufacture of plastic pipes are relatively simple.

Sustainability underground

by the production plants for manufacturing plastic pipes are relatively simple,” said Bray.

The main inputs are plastic pellets or powder and electricity. Production equipment is electrically powered, and heating is electric as temperatures required to melt the plastic are relatively low. This results in a clean and enclosed process.

“No combustion or chemical reaction is required, and therefore no smoke or emissions are produced,” she said.

PIPA and its members continue showing their commitment to sustainability and environmental responsibility. The members are program partners to Operation Clean Sweep, playing their role in working towards the prevention of pellet loss in Australia.

”Everyone in the industry has a role and responsibility to play throughout the supply chain,” said Bray. “It’s a collective effort where every little action counts and simple measures allow for effective results.”

Through manufacturing, scrap or re-work material generated is also re-used, designing out waste therefore aligning with circular economy principles. Suitable post-consumer and pre-consumer materials can also be used to manufacture non-pressure plastic pipes. Having said that, the volume of appropriate material in the waste streams is low. The industry is always looking at ways to work collaboratively across the broader industries to collect a sufficient volume of plastic pipes viable for recycling.

Durability is a result of product design

Part of the circular economy is to design a product that can remain functional without requiring excess maintenance or repair when

installed correctly under normal operation over its lifetime.

“For plastic pipes, it is intended that they can be installed and not require any maintenance or repair for decades, unlike other materials,” said Bray.

Plastic pipes withstand the forces they are subjected to. They do not corrode or crack, they resist chemical attack and abrasion while maintaining a smooth bore for easy fluid flow and better hydraulics. They are also designed not to leach secondary material into the fluid flow, necessary for drinking water applications. Plastic pipes are safe for the people and the planet.

“Plastic pipes offer clear advantages in terms of chemical resistance over other pipe options,” said Bray. “They are not affected by soil environments that are highly corrosive to metal and concrete. They are not affected by compounds that form in wastewater, such as acids that rapidly degrade iron and cement line pipes. It makes them the ideal choice for long-term infrastructure. They also have the lowest overall failure rates in water infrastructure compared to cast iron, ductile iron, steel, and asbestos cement”.

Plastic pipes are also lighter compared to other pipe materials. This has advantages during transportation – more volume per truckload – and when it comes to installation. For open trench installation, the use of plant

equipment is minimised compared to heavier pipe materials, which can increase lay rates and reduce CO2 emissions.

The versatility of plastic pipe systems allows for the option for trenchless installation as well, particularly with polyethylene pipe. This allows for fewer disruptions during the installation or repair of existing pipelines allowing flexibility and cost-effective installation and lowering the impact on the environment and community.

Re-use before recover

At the end of their long service life, plastic pipe systems in buried infrastructure applications can be reused without removing them from under the ground.

“These services are likely to become a host for a new plastic pipe,” said Bray. “There is a strong focus on recycling, but reusing the pipe significantly reduces the use of energy and resources. It also reduces the environmental impact of digging up a pipeline after 100 years. There are some applications where suitable recycling streams are available such as pipe off-cuts, but it’s not for all of them.

“By using recourses responsibility through better design, we are working smarter. We’re committed. And we’re working towards creating a healthier environment and sustainable future,” she said.

Collaboration on the Murray River

Mark Lamb is the CEO of the Murray Darling Association, looking after the needs of 172 local councils. He talked about the challenges and opportunities for councils within the Murray Darling Basin.

“ONGOING WATER AVAILABILITY

is one of the biggest challenges we face. There is a cyclical thing in the Basin where we seem to go from drought to flood and back again. While we have a lot of infrastructure, I’m not sure that we are looking at the issues the right way.”

This is just one concern of Mark Lamb, CEO of the Murray Darling Association. The Murray Darling Association (MDA) is the peak body for local government in the MurrayDarling Basin. It represents the interests of 172 councils over four states whose communities rely on water and resources within the Basin.

“One of the key challenges is trying to satisfy very many different needs of the communities that are across the basin,” said Lamb. “We represent local government areas

from Queensland all the way through to South Australia and everywhere in between. The MDA is looking to try and improve the quality and quantity of water so that they can satisfy the community’s needs.”

The MDA and communities With the outset that a healthy Murray-Darling Basin supports thriving communities, economic development, and sustainable productivity, the MDA ensures effective representation of local government and communities at a state and federal level in the management of Basin resources.

“It’s not just about the water, although that’s our prime focus. We are trying to engage with many municipal governments across Australia. The MDA is trying to help

them improve the situation for their communities,” he said.

To achieve this, the MDA advocates on behalf of Basin communities, explores sound solutions for regional issues through local knowledge and expertise, as well as facilitates debate regarding current issues and the future of the Basin.

“We split the MDA membership into regions. We’ve got 12 regions. They work their way down the Murray Darling Basin and all the way back up to the top into Queensland. By splitting the whole area into regions, we can try and reflect the different needs of each region,” said Lamb.

Challenges for MDA and the Murray River

Ongoing water availability is the prime concern for the MDA. Lamb and the MDA are looking at other issues, including infrastructure.

“Infrastructure upgrades are an ongoing issue, particularly regarding dams and irrigation,” he said. “One of the big questions is whether we need more infrastructure or upgrade what we have. It’s not to say whether dams are necessarily good or bad, but we need to look at the viability of future infrastructure. It’s about its economic feasibility and what it really means for that community, and potentially communities downstream.”

The MDA, officially the Murray Darling Association, represents 172 councils and shires along the length of the Murray River.

An unexpected challenge is the potential for rising sea levels. These two issues are difficult enough as it is, but they can combine for far more intimidating problems for the MDA and its member councils.

“We are considering the impact of rising sea levels because that’s going to be important in the lower Murray Darling Basin. Increasing salinity will impact the lower Murray, the Coorong, and the Lower Lakes Regions,” said Lamb.

Floodplain harvesting adds an additional layer of complexity. Lamb explained that it is part of a more complex question.

“Who actually controls that floodplain water when it floods?” he said. “Volume camps are an additional issue when it comes to environmental waters. How much water should any one license holder get? How much should be allowed for our communities? And how much is needed for environmental protection? Getting this balance right is not easy.”

Mark Lamb noted that water security across the Murray-Darling Basin is an ongoing issue for the Murray Darling Association.

“Following the 2022 Flood event, the onset of the El Nino, rising sea levels, and predicted diminishing water availability, water security is an ever-growing issue across the Basin,” Lamb said. “The MDA is exploring water security advocacy in context to water recovery programs, the MurrayDarling Basin Plan, ongoing disaster recovery efforts, and in preparation for the drought events in years to come.”

Doing good research to benefit every community

The MDA has been working with world-class researchers across the country to investigate ways to support communities and environmental protection at the same time.

“We have partnered with the CSIRO, who are doing very interesting work on managed aquifer recharge. It’s something that is not well understood, but I think it has real potential. It’s low cost but comes with almost zero evaporation losses. There’s a real opportunity for us to look at alternative ways to store water for the future,” said Lamb.

The circular economy is another area of research for both the MDA and CSIRO. While some might question the study of the circular economy under the auspices of the MDA, Lamb believes that this is an important area ripe for research.

“Water is part of the circular economy,” he said. “Our constitution does not just look at water but at the wellness and livelihood of communities. We’ve been working with the CSIRO to investigate and explore a series of strategic growth areas that align with the biggest land and water challenges faced by Australian governments/agencies, industries, and communities. These growth areas will build on our capabilities and that of our partners and transform the boundaries of the types of products, research projects and services we might collaborate on.”

Adding value to members

From Lamb’s point of view, it’s important to provide value to the members and the communities they represent. It’s where the Basin Communities Leadership Program comes into play by identifying, educating and mentoring the next generation of water leaders.

“It’s not just about being a leader in the water space. We also need leadership in local government. The feedback we were getting from communities is that people were going into local government without necessarily having had a

lot of training. This also applies to people who have wound up in a leadership role without having had any training. We developed the course so people can learn leadership skills,” said Lamb.

While the program finished in March 2022, there was enough interest in keeping the program alive. Lamb is working with employers throughout the regions to offer a customised program to leaders in their fields. He’s had interest from the dairy industry and One Basin CRC, and levels of collaboration across the Murray Darling Basin has been high.

“I have found that local government areas are very keen to collaborate. In terms of industries and private enterprise, I think a lot of these organisations see the importance of having a healthy river system.”

No hiding the sustainability mission

“WHILE PLAYING AFL in Melbourne, I developed a passion for wine, particularly premium wine,” said Vandenberg. “I liked some of the cabernets coming out of the Coonawarra region. It also turns out that one of my ancestors, Ari Vandenberg, was shipwrecked off Robe in the 1850s. Our vineyards are now in Guichen Bay, creating a family tie to the region. I thought getting a winery on the Limestone Coast was a great opportunity, and we took it.”

As an avid ocean kayaker, kite surfer, and paddle boarder, Vandenberg’s seen firsthand the destruction plastic waste has brought to ecosystems worldwide. The Hidden Sea mission was born from this experience. For him, it is about living with a higher purpose. When he wanted to start the Hidden Sea, Vandenberg knew it would be more than just wine.

“Justin (Moran, fellow founder) and I understood the importance of building a brand with purpose,” Vandenberg said. “We didn’t know collectively what that purpose would be, but we knew that’s what we wanted to build. That evolved because of where the Limestone Coast is and where the winery was situated. Coonawarra is effectively on the old seabed, which is the hidden sea. There’s the story of the whales, where you’ve got 26-millionyear-old fossilised whales sitting below vineyards. We had this real provenance story tied to the ocean.”

Moving from a purpose to sustainability

Both Vandenberg and Moran are lovers of the ocean. Due to the amount of time both men had spent in the sea, they both learned more about the issues with the ocean.

“Over time, we started supporting several ocean-based charities, including the Lonely Whale Foundation’s Stop Sucking campaign. We really wanted to do something tangible that could galvanise a tribe of people around a goal,” said Vandenberg.

That goal is to remove the equivalent of one billion plastic bottles from the ocean by 2030. For every bottle of the Hidden Sea purchased, their partners remove and recycle ten plastic bottles (or their equivalent) from the sea. Since July 2020, they have removed more than 22 million plastic bottles from the ocean through their partners.

Vandenberg acknowledges that he cannot pick and choose what they are taking from the ocean. However, he knows the importance of what he is talking about.

“We are not just taking plastic bottles from the ocean; we are taking any plastic our team encounters.

“The reason we talk about plastic bottles is that people understand what a plastic bottle is. It makes the messaging very simple and raises awareness far more effectively. At the same time, talking about one billion plastic bottles shows a tangible volume. People understand that it’s a vast volume.”

The ReSea Project is one of their primary collection partners. It has 47 fishermen that collect plastic from the ocean every day. Those numbers are tracked through blockchain technology, where it is bagged, tagged, and sorted. All that plastic is recycled and reused in Indonesia. A recent development is that no single

Former AFL footballer Richie Vandenberg is taking Hidden Sea Wines into uncharted waters by aiming to remove the equivalent of one billion plastic bottles from the ocean by 2030.

The vineyards are centred on Vandenberg’s family history on the Limestone Coast of South Australia.

piece is winding up in landfills. In terms of what they are collecting from the ocean, it is primarily plastic bags and plastic bottles. Despite the growing bans on plastic straws worldwide, this has yet to occur in Indonesia. As a result, the fishermen are also collecting a lot of straws.

How else does Hidden Sea focus on sustainability?

When it comes to waste, Vandenberg has worked hard to create a sustainable business, not just financially but environmentally. The entire winery is solar-powered and will receive its carbon-neutral accreditation soon. He is incredibly conscious of eliminating or minimising waste throughout the production process.

“We recycle all the wastewater onsite. Any water we cannot recycle goes out to water the blue gum forests behind the winery,” said Vandenberg. “At the same time, we are very conscious of how we use water, given that making wine is waterintensive. We have changed how we clean the bins and wash the tanks. We’ve introduced crossflow filters that require a hell of a lot less water.”

Vandenberg pointed out numerous areas across the winery where they look at waste streams. He cites the example of grape marc, the solid waste from pressing grapes into wine.

“We turn that grape marc into either feed for the animals or organic composts,” he said. “It’s not just about collecting plastic bottles; we have a whole sustainability philosophy. With the support of Sustainable Winegrowing Australia,

we are educating ourselves on how to be more sustainable. We reflect on the past 12 months and ask if we have improved our sustainability credentials.”

Sustainable Winegrowing Australia Vandenberg talked about the role that Sustainable Winegrowing Australia can play for consumers and wholesalers. He believes they can be vital in creating a nationally trusted standard.

“They are making it easy for everyone to understand a standard to adhere to,” he said. “I think it’s an essential element of sustainability in our industry. It’s very proactive, which I commend the industry for.”

Sustainable Winegrowing Australia has more than 1100 members, with over 270 certified members. Vandenberg believes that most vineyards across Australia are seeking certification, but it will take time and labour for the certification process to be complete.

Fast fact

Hidden Sea’s glass bottles can be recycled infinitely, with the labels laser-printed onto them. The waterbased organic inks are burned off in the recycling process. Its recyclable and sustainable cardboard cartons are 100 per cent recyclable after use.

“The most important thing for them right now is to get a weight of numbers on board, which is what they are doing. Once they’ve done that, they need to own that space and develop the trust in the mark,” Vandenberg said.

Hidden Sea has grown rapidly in the past three years. It has several other products to look at while it remains in its proof-of-concept phase. Vandenberg had to find out if enough consumers cared about removing plastic from the ocean.

“We feel like we have proven that over the past three years, we have gone from 3000 to 90,000 cases. The consumers are speaking with their feet or their wallets. Clearly, people get sustainability, and we give people a choice at the purchase level.”

Vandenberg has considered multiple aspects of sustainability in his venture.

Removing plastic from the ocean does not detract from producing highquality wine.

We are not just taking plastic bottles from the ocean; we are taking any plastic our team encounters.

The lighter side of water

ChatGPT a water guzzler?

Popular large language models such as OpenAI’s ChatGPT and Google’s Bard are energy intensive. They require massive server farms to provide enough data to train the powerful programs. Cooling those same data centres also makes the AI chatbots incredibly thirsty.

New research suggests training for GPT-3 alone consumed 185,000 gallons (700,000 litres) of water.

According to a recent study, an average user’s conversational exchange with ChatGPT amounts to dumping a large bottle of fresh water on the ground. Given the chatbot’s unprecedented popularity, researchers fear all those spilled bottles could take a troubling toll on water supplies, especially amid historic droughts and looming environmental uncertainty in the US.

Researchers from the University of California Riverside and the University of Texas Arlington published the AI water consumption estimates in a pre-print paper titled Making AI Less ‘Thirsty.’ The authors found that the amount of clear freshwater required

to train GPT-3 is equivalent to that needed to fill a nuclear reactor’s cooling tower.

That huge number of gallons could produce battery cells for 320 Teslas. From a similar perspective, ChatGPT would need to “drink” a 500-millilitre water bottle to complete a basic exchange with a user consisting of roughly 25-50 questions.

The vast number of gallons needed to train the AI model also assumes the training is happening in Microsoft’s state-of-the-art US data centre, built especially for OpenAI. The report notes that water consumption could be three times higher if the data were trained in the company’s less energy-efficient Asia data centre.

The researchers expect these water requirements to increase further with newer models, which rely on more data parameters than their predecessors.

“AI models’ water footprint can no longer stay under the radar,” the researchers said. “The water footprint must be addressed as a priority as part of the collective efforts to

combat global water challenges.”

When calculating AI’s water consumption, the researchers distinguish water “withdrawal” and “consumption.” Withdrawal physically removes water from a river, lake, or another source. Consumption refers to the loss of water by evaporation when it’s used in data centres. The research focused primarily on the consumption part of that equation, where the water can’t be recycled. Water consumption issues aren’t limited to OpenAI or AI models. In 2019, Google requested more than 2.3 billion gallons of water for data centres in just three states. The company currently has 14 data centres spread across North America. According to the paper, Google’s LaMDA could require millions of litres of water to train up to a usable level. This is larger than GPT-3 because several of Google’s thirsty data centres are housed in hot states such as Texas. However, researchers issued a caveat with this estimation, calling it an “approximate reference point.”

To finish each issue, we aim to look at the lighter side of water and waterrelated issues. If you’ve seen an amusing story, let us know so we can consider it for the next issue.
