Editor’s letter

Clemence Carayol

Welcome to this autumn edition of Trenchless Australasia

As an editor, it is the first time I have worked on a publication revolving around oil, gas, and energies, and thanks to Trenchless Australasia and its team, I have learnt so much.

I have learnt about who are the industry leaders in this very special industry.

I have also learnt how important and broad it is: trenchless technology has been used on what matters most in everyone’s life, such as water, wastewater, energy and communications infrastructures for decades now.

As I was finalising the pages of this edition of Trenchless Australasia, I immersed myself in what made this industry so unique as I learnt more about it every day.

It has been truly humbling to learn about all the distinct elements that compose the Australia and New Zealand’s trenchless technology industry, and how this industry is truly the backbone of our every day’s life.

Learning so many new terminologies has been fulfilling – HDD, microtunnelling, pipe jacking, pipe ramming have become part of my everyday language.

For this edition, we will focus on emission reduction, a topic that has become more and more prominent in the past decade.

Since emissions come mainly from energy combustion, it’s only normal that the very same industry should play a role in reducing these emissions.

This theme is also in line with this year’s No-Dig Down Under 2023 conference, as the event’s motto this year is “better outcomes through trenchless.”

offer 10 utility and council scholarships for attendance at No-Dig Down Under 2023.

Three training sessions organised by the ASTT will focus on new installations good practices, whereas the second will be all about horizontal directional drilling, while the third will be pipelining orientated.

How to be more sustainable is crucial, and this is also at the very core of Pipe Core’s interest when it comes to making trenchless pipeline rehabilitation more sustainable.

Hence why the company has added SAERTEX-LINER UPgreen to its portfolio, a technology which impressively, since its launch two years ago, has enabled savings of one million kilograms of CO2, which our readers will be able to learn more about as they turn the pages of this magazine.

Reducing emissions is also very much at the heart of Empire Infrastructure’s philosophy. This edition of Trenchless Australasia highlights a Future Pipe Industries’ range of projects, distributed by Empire Infrastructure.

Future Pipe Industries has a comprehensive environmental, health and safety management program and all manufacturing units are committed to the group environmental and safety policy.

This product range is also equally committed to reducing our environmental impact. As with safety goals, each manufacturing facility has environmental initiatives focused on responsible use of energy and water and on waste reduction.

Printed by: Manark Printing 28 Dingley Ave Dandenong VIC 3175 Ph: (03) 9794 8337

This encompasses better environmental outcomes, from less wildlife disturbance and pollution, but also better community outcomes, from reduced disruption to essential roads and services as well as better financial outcomes, from lower costs for major projects.

I hope that, as you turn the pages of Trenchless Australasia, you will find as much pleasure reading it as we had while we were writing the magazine.

Happy reading!

President’s Message

With a full quarter of 2023 down, I hope you can reflect on the start of the year being a rewarding and a positive one. To date, 2023 has been a good one for the ASTT and currently we are planning for our Annual General Meeting; of which you are invited to. Details are communicated on our website.

This edition of Trenchless Australasia is themed “trenchless going green” and I’m sure you will enjoy reading the articles focused on our overarching infrastructure industry as we pivot to a green and renewable approach. At the ASTT we see infrastructure pivoting to ensure we achieve net zero in the coming decades which will positively affect the buoyancy of our trenchless products, services, manufacturing and projects.

This year we are seeing more than normal change with our Council, and I will take this opportunity to thank our outgoing Council members in Justin Shepherd and Matthew Boyle. Both Justin and Matt have been instrumental in helping our industry and the ASTT and we appreciate their efforts. Both Justin’s and Matt’s careers are turning away from trenchless, and we support their desire to resign from Council and we wish them the best in the future. With the old comes the new, and we are very excited to welcome our new Councillors in Ash Hamer and Jiang Aizezi. We welcome both Ash and Jiang as they are formally appointed at the AGM in April 2023. Ash and Jiang are passionate about trenchless, and we are looking forward to working with them in some of the new initiatives that we are rolling out in the near future.

Another key change with the Council Structure is the resignation and retirement of Jeff Pace, having been our Security and Treasurer since our incorporation in 1991! Jeff has been an amazing asset to the ASTT over the 30 plus years and he will be sadly missed. We wish Jeff well in his “full retirement” decision that has been on his mind for a few years now. More recognition for Jeff’s amazing commitment to the ASTT and our industry will follow. Jeff hands over to another longterm industry supporter in Trevor Gosatti, and fortunately Trevor will slot into the role having worked in the ASTT for over 20 years as either

a Councillor or as our President.

The Conference theme this year is “Better Outcomes Through Trenchless”, and it is this theme we plan to stimulate the conversation and influence the papers, the exhibitors, and the panel discussion on improving the service industry with better design, better method selection and better overall solutions.

Given that the Conference is five months away, it is again shaping up to be a huge success. With over 95 per cent of the exhibition space sold there is little time to ponder, we’d love to see you showcase your services and products at No-Dig Down Under 2023.

A special thanks goes to our consistent and new supporters of the conference:

Platinum – Rob Carr

Gold – Vermeer

Silver – Rockpecker and Interflow. Successful conferences wouldn’t be possible without the commitment of these companies and all those others that take a booth, commit their time and effort to tell us all about their products and services. We appreciate your input which make our conferences a success. Council will continue to work through the allimportant key actions during 2023:

• The annual ASTT AGM

• The roll out of our Strategic Action Plan

• The finalisation of our Liner Design Specification

• The finalisation of the Liner Design Training Package

• The continuation of the updates to our NASTT licenced training packages

• The compilation of the report: The State of the Industry (Trenchless)

• The partnership with AusJet

• The partnership with WSAA.

All these initiatives are designed to deploy the membership resources to benefit the industry and the membership in one way or another. A reminder to our members; if there is something that you feel we as the peak trenchless body should be working on, please reach out and contact either myself or your local Councillor.

New Secretary/Treasurer for the ASTT This is my last Secretaries Corner report. After much deliberation, I have decided to throw in the towel and officially retire from my position as your ASTT Secretary/ Treasurer effective from April 27, 2023 It has certainly been an amazing ride throughout these past 32 years. We have come a long way since our beginning back in 1991. Although no longer with us, I would like to especially thank Menno Henneveld for having the vision to come up with the idea to create a society and giving me the op-portunity to fulfill this task and continue to manage it for all of you. His legacy lives on. I would also like to thank you the members for allowing me to represent you all over this period. It was an honour to work alongside you all and learn all the amazing advancement that trenchless technology has realised over this long period.

We the ASTT have accomplished a tremendous amount over this time and are now recognized as one of the most efficient societies of all the other Affiliated societies worldwide.

We continue to produce world class International and National conferences and exhibitions that are the envy of the world. This is partly due to the team at Prime Creative Media (PCM) who ensure we get the best out of these shows and also have fun at the same time. PCM also now produce our Trenchless Australasia magazine a task I was so pleased to hand over in 2004 as I found it extremely difficult to produce our modest newsletters for a circulation of 200.

I will miss the time I had being involved with the ISTT as your representative, however I will not miss the 11pm regular

meetings that the ISTT has. It goes without saying that there will be a gap in my life due to not catching up with all the ASTT and affiliated society members both locally and overseas at the conferences. I will also miss the daily checking of emails that has kept me busy every day since email was introduced.

And finally I can announce prior to the AGM that you will have a new Secretary/Treasurer namely Trevor Gosatti, effective from April 27, 2023. I wish Trevor all the best and I am confident he will not dissappoint you all. I want to wish the ASTT Councillors and you the members, both past and present, all the best, and who knows, you might see me at times pop up at some of our events.

Trenchless Australasia Magazines now online Following several requests from the members and providing yet another benefit to members, I can now confirm that past editions of Trenchless Australasia from June 2020 to date can now be downloaded directly from the ASTT members only area of our website.

Refer to the new heading shown as MAGAZINES at astt.wildapricot.org/ Magazines.

Innovative product protecting trenchless contractors from costly and dangerous asset strikes

Conceived specifically for the trenchless and civil construction industries, The Safety Shovel simultaneously detects metal and power under the ground, preventing harmful asset strikes before they happen.

The Safety Shovel is designed to be used as a supportive tool to protect workers from harmful events, resulting from asset strikes.

Although best endeavours are deployed to prevent infrastructure strikes, records that are inaccurate deliver risk that cannot be minimised without advanced tooling. The Safety Shovel provides a functional real time detection tool to protect workers by simultaneously detecting metal objects and electrical cables (EMF) under the ground.

With alignment to Australian excavation standards, The Safety Shovel allows workers to operate within the exclusion zone and detect materials and cables that – if damaged – would result in a major Occupational Health, Safety & Environmental OHSE event or asset strike.

Typical assets detected include, water and gas pipes, communications cables, as well as live power cables.

The Safety Shovel compliments the efforts of Before You Dig and alerts excavation teams of potential danger before they happen.

Trenchless industry celebrates International Women’s Day

The trenchless industry has come together to celebrate the women who help keep the industry running.

International Women’s Day (IWD) 2023 is an opportunity for companies to foreground the hard work and dedication of their female employees, and the trenchless industry has answered the call. From suppliers like Vermeer and SECA to inspection service providers like VAPAR and training companies like DBYD Certification – no-dig operators have announced their support and encouragement for women in the industry.

In a Linkedin post Kristel Hudson, SECA’s Marketing and Coms lead, said that operators must acknowledge the challenges and obstacles that women still face today.

“This day is a reminder of the resilience and strength that women possess, and how we have continued to break down barriers and pave the way for future generations,” she said.

“To my female colleagues, you are an inspiration to me and those around you. You have shown incredible strength, perseverance, and dedication to your work, family and friendships and I am proud to work alongside you.”

IWD 2023’s theme is ‘Embrace Equity’.

Vermeer manager supports Leukaemia Foundation with World’s Greatest Shave

One of Vermeer Australia’s Area Manager’s, Tristan Jackson did the World’s Greatest Shave and raised $7,637 for the Leukaemia Foundation.

The money raised was in support of the Leukaemia Foundation, which offers expert support, funds leading-edge research and campaigns to make change for Australians facing blood cancer.

“To say I am overwhelmed by the support from everyone, is an understatement. I am truly in awe of the generosity that people have shown, and how together we can make a difference,” said Jackson.

“Thank you to everyone, who donated, helped

and supported me in raising such a significant amount for the Leukaemia Foundation by doing the World’s Greatest Shave.”

Jackson proceeded then to thank Vermeer, RDO Equipment and L&M Trenchless – among others – for their support.

The organisation’s first World’s Greatest Shave dates back to the late nineties, when the challenge was then named Shave for a Cure. This year, World’s Greatest Shave is hitting its 25th milestone, making it one of Australia’s longest running and most iconic fundraising events.

Over the last quarter-century, more than 2 million Aussies have taken part – with an estimated 39,000 kilograms of hair removed. Be like Jackson, “be brave and shave”, as the Leukaemia Foundation’s motto says.

Merredin Shire Council authorises wastewater pipes refurbishment

Merredin Shire’s authorised contractor Allpipe Technologies will soon commence work to refurbish ageing wastewater pipes.

This refurbishment work executed by Allpipe Technologies is set to commence in mid-March 2023 and completed by late July 2023 and will take place across the town of Merredin. Allpipe Technologies will be working in both verges and/or roads, and also in the boundary of private properties. Sewer relining uses trenchless technology to clean and refurbish existing wastewater pipes.

It reduces the likelihood of blockages and extends the life of this important infrastructure by at least 30 years.

Residents and businesses may notice more activity in the area, noise from generators and vehicles and temporary odour. Traffic management will be in place to direct vehicles, cyclists and pedestrians safely around the work area. Night works may occasionally be required and access to property might be requested, and in both cases, the shire will notify impacted residents in advance.

Primus Line® flies the flag

for

trenchless solutions in sensitive locations

Primus Line has illustrated the benefits of trenchless technology for pipeline rehabilitation in culturally sensitive areas during two installations for one of the world’s leading mining companies.

Trenchless methods, such as Primus Line, are the perfect solution to overcome the challenges of pipeline works in areas of cultural significant importance and preserve them to traditional landowners.

The benefits of Primus Line was recently proven during two Rio Tinto projects using the technology in areas of cultural heritage sensitivity in Western Australia.

The first project took place near Cape Lambert and included the renovation of a 1500 m long high-density polyethylene (HDPE) pipeline. The second installation was in the outback near Paraburdoo where a 1000 m of cement-lined mild steel pipeline was rehabilitated.

Primus Line is a flexible, safe and reliable pipeline relining technology that reduces earth movements to a minimum, usually only requiring two small construction pits at the beginning and the end of the pipeline section to be rehabilitated.

Thus, the areas of cultural heritage sensitivity remain completely untouched.

The liner comes pre-coiled on transport spools with a length up to 1000

The refurbishment work executed by Allpipe Technologies is set to commence in mid-March 2023 and will take place across the town of Merredin.

South Australia hits every curveball

Trenchless operators in South Australia have been assisting in flood relief and expanding infrastructure ahead of a potential game-changing innovation in the world of wastewater pipe corrosion prevention.

In service to people

SA Water and Interflow’s efforts to support flooded towns and communities throughout Australia in 2022 haven’t ceased.

After heavy rain in Queensland, New South Wales and Victoria caused exceptional flooding late last year in several towns along the length of the Murray River in Southern Australia, SA Water and Interflow’s help towards the impacted communities continue.

With the water only now starting to recede in the last few weeks, this help is more than necessary today.

Located 84 kilometres east of Adelaide lies the historic town of Mannum, on the west bank of the river, where a number of properties became inundated with floodwaters.

“Some of these low-lying properties feed into the common wastewater main, and if nothing was done the river could have freely flowed into the wastewater network, inundating pump stations and impacting SA WaterCorp’s ability to provide wastewater services to some of their local customers,” shared the Interflow team.

“Early on in the event, SA Water put several actions in place to help mitigate this

challenge, including calling on some of its contract partners, such as Interflow.”

Interflow welcomed its ongoing collaboration with SA Water to support local communities.

“Working consistently over three weeks, together with SA Water, we isolated required properties from the local wastewater network, through patching and sealing, and continue to work with the utility now, gradually restoring services as the floodwaters recede,” said the Interflow team.

“We’re proud of the SA Water and Interflow teams’ quick response through the floods, and for supporting the local communities.”

Healthy expansion

SA Water is investing $155 million in a water main management program that is affecting its extensive network.

The utility has begun works to replace 55 metres of water mains in Mount Barker, around the heritage SteamRanger tracks.

In order to minimise the environmental and community impacts of the work, the utility company has decided to use horizontal directional drilling (HDD) at a depth of 2.4 metres underneath Mount Barker’s heritage SteamRanger tracks.

The section of pipe being replaced is critical to the water service in Mt Barker and surrounds.

Amanda Lewry, SA Water’s General Manager of Sustainable Infrastructure said that HDD is considered to be safer and more efficient for the project.

“These works are part of our efforts to continually improve water services for our customers, with this section of pipe critical to transporting water to residents and businesses in and around Mount Barker,” she said.

“Together with our contractors, we’re committed to minimising any impacts to the community during the works, such as dust or noise caused by the use of heavy machinery and increased vehicle movement in and out of our worksite.”

Work will be timed for periods in which the SteamRanger is not operating.

Bright future

Researchers from The University of South Australia and the University of Queensland have developed self-healing concrete that may use waste to mitigate corrosion in Australia’s sewer pipes.

Professor Yan Zhuge, Professor of Structural Engineering from the University of South

South Australia is in a growth mindset with trenchless operating leading the way.

Australia, is leading the trial of a an innovative solution for dealing with the corrosion of concrete pipes.

Developed alongside researchers from the University of Queensland, the trial will use pipes that are manufactured from concrete that contains microcapsules filled with a mix of alum sludge and calcium hydroxide, which are added in the final step of mixing the concrete.

The microcapsules have a pH-sensitive shell that will respond to acidic buildup by breaking own and releasing the contents, which act as healing agents and makes the concrete highly resistant to microbially-induced corrosion.

The capsules have a pH-sensitive shell so that they can respond when the pH of the pipes reaches a certain point – a change caused by the corrosive acid from sulphur-oxidising bacteria in wastewater.

“This technology will not only extend the lifetime of concrete structures, saving the Australian economy more than $1 billion, but it will promote a circular economy as well by reusing sludge that would normally end up in landfill,” Zhuge said.

This reuse of waste will be essential to the carbon-neutral aspirations of many industry operators.

“Mainland Australia alone has about 400 drinking water treatment plants, with a single site annually generating up to 2000 tonnes of treated water sludge,” said Zhuge. “Most of that is disposed of in landfill, costing more than $6 million each year, as well as causing severe environmental issues.”

By utilising waste product from wastewater treatment plants in the sludge, the research has the potential to generate a circular economy – an essential element as all industries attempt to decrease their carbon footprint as much as possible.

At L&D Micro Tunnelling we specialize in laser guided boring. Our Tunnel bore machines use a vacuum extraction system where all spoil is sucked into interceptor tanks for easy disposal with no mess. All our heads are hydraulically driven and guided by a high accuracy laser to achieve precision over long distances.

The field joints for the DN250 FBE coated pipeline were prepared to SA 2.5 (abrasive blast clean) prior to the contractor applying Protal 7700™ (rapid cure, high build epoxy) as the Field Joint Coating (FJC) at a nominal Dry Film Thickness (DFT) of 1000 microns via airless spray guns from 1000ml cartridges.

Following the inspection for both the mainline coating and field joint coating, Denso BoreWrap™ was applied on site in a two-layer system to protect against the abrasion, impact, gouging and shearing impacts which are to be expected

Wrapping up the challenges in SA

In December 2022, Denso Australia completed the supply of a project involving the protection of 400 lineal metres of DN250 mild steel pipeline in Bolivar, South Australia.

when undertaking Horizontal Directional Drilling (HDD) installations.

Denso Bore-Wrap™ is designed to protect the underlying corrosion system and work efficiently with the cathodic protection system as it is a nonshielding Abrasion Resistant Outerwrap (ARO).

The ease of application for both the Protal & Bore-Wrap products contributed greatly to cost savings in labour and QA. In addition, the successful application of these products has assured that both the client’s asset as well as the corrosion coating are protected long-term through the rigours of the HDD installation.

Denso (Australia), is a subsidiary of Winn & Coales International and specialise in the manufacture and supply of corrosion and chemical resistant coatings and linings for the long-term protection of steel, concrete and timber surfaces in the toughest corrosive environments.

The company is at the forefront of innovative corrosion prevention technology and has a focus on developing an extensive range of custom solutions to meet the specific needs of different industries.

Denso’s full range of products are manufactured to comply with the strict quality standards. The products are designed for

longevity, with corrosion prevention solutions that can offer up to 30-plus years of maintenance free service.

Rob Carr begins construction of important Brisbane sewer in $45m Urban Utilities project

Microtunnelling contractor, Rob Carr, has commenced construction of a new 1 km long wastewater pipe running under the heart of Brisbane, Queensland. The Urban Utilities project is part of a major infrastructure upgrade to cater for population growth in the city’s north, which is expected to increase by 37,000 over the next 30 years.

An Australian Bureau of Statistics report based on data from 2019-2020, found greater Brisbane’s population was growing faster than anywhere else in the country, at a rate of 1.9 per cent per year, and its popular northern suburbs are booming. Urban Utilities is responsible for providing reliable water and wastewater services for the growing city, with the utility servicing more than 1.6 million customers across Brisbane, Ipswich, Scenic Rim, Somerset and Lockyer Valley local council areas in South East Queensland.

To cater for the expected 37,000 additional people in the north Brisbane region who will be relying on the utility’s services over the next 30 years, Urban Utilities is investing $45 million to upgrade the area’s essential wastewater network, by building the Breakfast Creek Trunk Sewer Main Upgrade. Stretching from Bowen Hills to Windsor, the 1 km long and 1.8 m internal diameter pipeline will be one of the largest in the utility’s 9000 km wastewater network, transporting up to 400 L of wastewater per second once complete.

Urban Utilities spokesperson Michelle Cull says the project is a key aspect of the organisation’s plans to support population growth in the region.

“We plan well ahead for the future and the population in this catchment area on Brisbane’s northside is expected to grow by around 40 per cent over the next three decades,” she says.

“That means a lot more toilets flushing, washing machines running and showers being used, so it’s important we continue to invest in essential infrastructure for our growing community. The new sewer will run beneath some of Brisbane’s busiest roads, including the Inner City Bypass, and will transport the wastewater from thousands of homes and businesses to our Luggage Point Resource Recovery Centre, where it’s treated.”

Construction of the sewer will utilise microtunnelling, with Rob Carr contracted by Urban Utilities’ delivery partner Fulton Hogan Utilities to complete the trenchless design and construction, taking place at depths of up to 14 m, around four storeys, below ground.

“By using this state-of-the-art technology,

we’re able to carry out this significant upgrade while minimising impacts on traffic, customers and the community,” says Cull.

“The project is a feat of engineering and it’s a far cry from the traditional tunnelling methods used by miners to build the city’s largest and oldest sewer pipe – the S1 Main Sewer – in 1915.”

Rob Carr general manager Angelo Soumboulidis says the company was contracted for the project after working closely with Fulton Hogan Utilities on a design which leveraged innovation.

“We have a strong reputation as a leader and innovator in the industry with a proven track record of delivering high-quality work,” he says.

“Working closely with our client, Fulton Hogan Utilities, our innovative final design solution minimised disruption to the surrounding community and limited environmental impact.

“Our commitment to providing innovative solutions to our clients’ needs and our dedication to delivering exceptional customer service were also key factors in our selection for this project.”

Rob Carr is using a 29 t Herrenknecht microtunnel boring machine (MTBM) named Leila Perry after the granddaughter of George Edmonstone, a politician who made significant contributions to Brisbane in the late 1800s. The family has also gifted the land where construction of the project is taking place.

The 29 t MTBM is also one-of-a-kind, having been transformed into a colourful work of art created by a local high school student. The design is inspired by Brisbane, representing the city’s iconic jacaranda trees, the Brisbane River and Story Bridge.

On 13 March, the MTBM was lowered into the launch shaft in Perry Park, on the corner of Folkstone St and Edmonstone Rd in Bowen Hills, beginning its journey west towards Windsor. The machine will pass underneath the Inner City Bypass before reaching a retrieval shaft adjacent to the Airport Link northbound entry ramp and Lutwyche Road intersection where it will be recovered.

The MTBM will tunnel through Brisbane tuff rock up to 150 MPa traversing an innovative alignment, and will use pipejacking to install 334 lengths of reinforced concrete pipe which will form the new sewer main as it progresses.

Rob Carr project manager Thierry Candito says the contractor is excited to be contributing to such an important project, ensuring the growing city of Brisbane can continue to enjoy essential services now and into the future.

“This project is very interesting and challenging,” he says.

“The pipejacking operation is only one part of the project. We have many activities happening in parallel that we need to plan and coordinate carefully.”

To be ready for the MTBM launch, Rob Carr first had to excavate and complete an underpinned segmental shaft up to 15 m deep. In parallel, the company started construction of the first stage of connecting the tunnel with Urban Utilities’ existing S1 sewer.

While this work was ongoing, the contractor also installed a 10 t portal crane on the surface, which will provide logistical support for deliveries to site and lower jacking pipe to the foot of the shaft. The company is also concurrently constructing the receival shaft using the caisson sinking technique.

Once the MBTM completes its journey to Windsor, Rob Carr will undertake high density polyethylene welding of the pipe joints, while also carrying out the second stage of the S1 tunnel connection. Once this has been completed, Rob Carr will move onto constructing maintenance holes at either end of

the pipeline alignment.

Candito says the experience and knowledge of Rob Carr in delivering complex projects will help them to meet three of the key challenging aspects of the installation, including the MTBM passing under a live rail crossing.

“We are working closely with our client Fulton Hogan Utilities and Queensland Rail for this operation, and are implementing a 24/7 rail monitoring system,” he says.

“We have selected the optimum location to set up a theodolite that will continuously check target prisms installed along the rail. Through a cloud-based website, we will be able to monitor the rails in real time while the MTBM operates underneath.

“With this live input, we will be able to better manage the operation of the machine.”

The MTBM will also travel underneath

a creek in the area and Rob Carr is working with Fulton Hogan Utilities to finalise the parameters and a process for executing this important section of the alignment.

“We have completed additional boreholes and a geotechnical investigation to have the most accurate data along the tunnel alignment,” says Candito.

“We have completed an MTBM face pressure analysis with the data received and are now reviewing it with third parties to ensure it is satisfactory. We also plan to stop the machine prior the creek, complete cutter head maintenance and check machine’s system, allowing us to mitigate risks of a breakdown or maintenance while traveling below the waterway.

“Finally, the last challenge is our people, who are the ones making this project a reality. We need to ensure they are working in the best environment possible and give them the opportunity to continue to grow throughout the project and keep them safe.”

Soumboulidis says the project is an opportunity for the company to once again illustrate its expertise in microtunnelling and trenchless pipeline construction.

“The project is incredibly important to Rob Carr as it represents our commitment to providing innovative and cost-effective solutions that meet our clients’ needs,” he says.

“We are able to showcase our expertise in microtunnelling and complex civil works, delivering efficient solutions, whilst simultaneously minimising our environmental impact.”

Construction of the project is expected to take 18 months and be completed in 2024.

The unique challenges of maintaining coastal sewer infrastructure

Due to its location on the east coast of Australia, Central Coast Council’s sewer network experiences a range of challenges that differ from inland asset owners.

Jamie Loader is the Central Coast Council’s Director Water and Sewer, overlooking the entire reticulated system – including 2600 kilometres of sewer mains, 320 pump stations and eight treatment plants.

Loader tells Trenchless Australasia that it can be hard to identify minor issues, meaning that sometimes faults are only seen when there is a system failure.

“There’s a range of things that will contribute to damaging the sewer network,” says Loader. “Anything from ageing infrastructure, tree

root intrusion, cross connections from private properties where they’ve connected their sewer in the storm water, either deliberately or unknowingly.”

“Even just movement within the soil can sometimes dislodge pipe connections.”

Unique to coastal regions, however, is the ingress of salt water – which speeds up corrosion of water assets.

“Flooding is also more frequent in coastal areas – storm surges and sea-levels rising can contribute to infiltration,” Loader says.

The combination of a number of ecologically sensitive locations in the area and the dense urban population along the coast means that, when leaks do happen, the impact can be exaggerated compared to less complex urban environments, with public health being at the forefront.

Late in 2022, the combination of these various pressures on the system resulted in Terrigal Beach – in the southeast of the council’s jurisdiction – receiving a poor water quality rating, partially due to

sewer infiltration. In response, the council commenced a massive relining program to mitigate the sewer outflow that was contributing to pollution in the area.

Since the pollution at Terrigal Beach was identified, Central Coast Council has relined over 125 kms of sewer mains. Contractors working on this effort are using spiral-wound liner on most of the system. Larger pipes, however, have required cured-inplace pipe (CIP)

“We have another 93 km to replace in the next five years – 25 km of which will be done in this financial year,” says Loader. “Plus, we’ve got about 1000 kms of vulnerable material – sewer gravity mains that will be assessed for relining.”

Asset management on this kind of scale required by the council’s network is an ongoing task.

“It’s kind of like painting the Harbour Bridge. By the time you’ve inspected the whole network, it’s time to go back to the start,” Loader says.

To stay proactive in its asset management activities, the council combines the services of a dedicated, full time CCTV inspection crew with more reactive, issue-specific operators that respond to specific blocks or leaks as they occur in the network.

The whole operation is organised through a kind of triage system. The council has all the data regarding different parts of the sewer

network – the age of the pipes, time since last inspection, condition, pipe material. This information is assessed so that the council knows where best to deploy its resources.

“We’re currently developing the Water and Sewer Master Plan,” says Loader.

“We’re analysing the network assessing the brownfield areas that aren’t connected to it and determining if and how they should be.”

Loader says Central Coast Council has been identified as a growth council.

“We have a lot of developer-led infrastructure being installed so Council’s role is to ensure that our trunk mains and treatment plants are suitably sized to accommodate the increased population,” he says.

Future Pipe Industries’ ongoing commitment to reducing carbon emissions

Future Pipe Industries is committed to ensuring minimal impact on the environment throughout its manufacturing process. The company’s commitment to reducing emissions is undeniable and its latest recent Environmental Product Declaration (EPD) is a testimony to the brand’s commitment to sustainability. Future pipes workforce includes more that 3300 staff. Globally there has been more than 190,000 metres of Future Pipe products installed.

Designing, manufacturing and supplying composite piping systems, Future Pipe Industries services the industrial, oil and gas, water and marine, offshore, as well as trenchless sectors.

The company’s jacking pipes for instance, solely for trenchless applications is – just like all other Future Pipe Industries productsmade from glass fibre reinforcements that are embedded in cured thermosetting resin.

Environmental protection is one of the main pillars of the company’s corporate purpose, as it is an integral part of the business strategy and ranks equally with other company objectives, in the form of a comprehensive environmental, health and safety management program.

Director of Sales and Operations at Empire Infrastructure Aaron Mackley, says Future Pipe Industries stated purpose is “to deliver water and energy to the world in the most efficient and sustainable way”.

“Our Corporate Purpose is rooted in the knowledge that by conducting our business operations responsibly we will create shared value for all stakeholders,” says Mackley.

“From Future Pipe’s Corporate Purpose through to the actions we take every day, we recognize sustainability is a business imperative which needs to take place at both a strategic and

operational level.”

As with safety goals, each manufacturing facility has environmental initiatives focused on responsible use of energy and water and on waste reduction.

Through its most recent Environmental Product Declaration, Future Pipe Industries has proven how eco-friendly glass reinforced polymer pipe can be. The declaration was peer reviewed by the IVL Swedish Environmental Research Institute Secretariat of the International EPD® System.

This environmental product declaration comprises the full life cycle of glass reinforced polymer, which is a composite material that consists of a polymer matrix and glass fibres.

The polymer matrix is typically an epoxy, vinylester or polyester thermosetting resin.

The resin brings the environmental and chemical resistance to the product, while the glass fibres add strength to the composite material.

With their material selection and advanced processes, Future Pipe is able to deliver composite piping systems to projects which span petrochemical, desalination, sea water intake systems, brine lines, water transmission, waste water treatment, sewer and drainage and topside piping as just a few examples.

The nature of our business means that we need to understand and carefully manage our impact on the environment. We also have a major responsibility and opportunity to convert the world’s pipe systems to the longer term, more environmentally friendly composite pipe.

Mackley says Future Pipe Industries’ products tick many boxes, as they are very long lasting and less energy is required to produce composite pipes, making them environmentally friendly and sustainable.

“They are durable, cost effective and efficient, as well as versatile,” he says.

All manufacturing sites operate under a certified quality (ISO 9001), environmental (ISO 14001) and health and safety (ISO 45001) management system.

SAERTEX-LINER® MULTI saves

1 million kg of CO2 emissions

SAERTEX multiCom® GmbH are firmly commited to significantly reduce the CO2 footprint of its MULTI S+ Liners by using unsaturated polyester resins, aiming to make trenchless pipeline rehabilitation more sustainable.

Together with its strategic partner Scott Bader, SAERTEX multiCom are able to utilise a more climate-friendly manufacturing process for its resin systems.

Impressively, since implementing this change, savings of 1 million kilograms of CO2 within a single year have become possible. This corresponds to the CO2 footprint of 2717 flights from Frankfurt-am-Main to New York.

“The new SAERTEX-LINER UPgreen technology has enabled us to reach our target and, together with our customers, we have taken another step towards greater sustainability,” says SAERTEX multiCom Director Sales Europe, Africa and Southern Africa, Stephan Raab.

The environmentally-friendly conversion to the UP resin system does not affect the products’ technical characteristics and corresponds with all product approvals that exist around the globe.

“We focused from the very beginning on

sustainable orientation of our entire sector encourage and motivate us to take further steps,” says Kai Diecks, Global Managing Director at SAERTEX multiCom.

Motivated by these results, customers are returning time and time again to use SAERTEX multiCom products as a sustainable rehabilitation option for supply and wastewater pipes, with huge growth seen in recent years via Pipe Core, SAERTEX multiCom’s distributor

with such impressive material characteristics for the trenchless rehabilitation of municipal wastewater pipes and pressure lines and has a worldwide proven record of over 100,000 installations.

Pipe Core customer, Raad Al-Karbouli, Director and General Manager of NZ Lining chooses SAERTEX-LINER MULTI when he tackles the rehabilitation of wastewater and stormwater pipes as “it is the most efficient, flexible and sustainable choice on the market”.

On one project in 2022, over 5 tons of CO2 emissions were saved.

Furthermore, Neil Kermeen, Managing Director at Rangedale Group also favours the products for his jobs rehabilitating critically damaged underground infrastructure in Australia.

“With a business model focused on no-dig methods of rehabilitation, we were pleased to see the positive steps SAERTEX multiCom has taken with the support of Pipe Core to reduce their carbon footprint,” he says.

On a recent project between September 2022 and April 2023, SAERTEX-LINER achieved a reduction of 7 tons of CO2 for Rangedale Rehabilitation & Renewals.

Initial measures to determine the CO2 footprint and introduce an environmental management system for certification to the international DIN EN ISO 14001 environmental management standard have already been implemented.

“We are consequently working on a comprehensive sustainability strategy for

Closing the recycling loop

Angar Environmental is a recycling company that is playing a significant role in keeping construction waste out of landfills by repurposing it back into the industry,” Operations Manager Pat Gough explains.

“With our facility in Keilor East operating at full capacity, Angar Environmental produces 35,000 cubic metres per annum of recycled materials, with 60 per cent of it being returned to the industry for dedicated reuse.”

“We specialise in recycling non-destructive digging (NDD)/drilling slurries and sludges, and runs a roll on/roll off waste management system across a broad range of projects throughout Victoria.”

What sets Angar Environmental apart from its competitors is its commitment to building a cleaner future for the environment. The clean-fill recycling plant processes large ballast used for access roads and free stand areas, quarter minus and 10 to 25 mm aggregates used in the plumbing and drainage industries. Fine soils and clay are used for capping and blending and as bedding under porous soils to retain moisture and give commercial productivity to farming acreage. The remaining water is put through a two-stage filtering and recycling system and used for plant processing, vehicle, and free-stand wash down, eliminating the operation’s need for domestic water. The converted end products are 100 per cent recyclable.

Angar’s depots located in Altona, Keilor East, Dandenong, and Epping are strategically placed to service a large range of projects, providing an excellent disposal location for current and upcoming projects planned for Melbourne. The company has slurry bins scattered around the state with horizontal directional (HDD) drillers, providing services to several projects across Victoria, including the Westgate Tunnel Project, Shepparton Rail line upgrade, Gippsland line upgrade, and several level crossing removals.

“Our company’s growth has been impressive, from three employees on start-up to now employing 26 people and processing up to 150 tonnes of NDD waste per shift,” Director Andrew McIntosh says.

“Angar Environmental has plans to grow its

It was 2015 when Angar Environmental Services saw a gap in the non-destructive digging industry to recycle and repurpose current clean slurry waste that was going into landfill.

larger range of materials in the future. The company also sees the merit and opportunity to work with similar recycling groups within the industry to optimise the reuse of materials.”

“Our success is built on serviceability and customer relations. We are committed to being flexible with our clients’ needs and requirements, and our slurry bins and hook trucks on site have proven to increase client’s productivity, reducing the CoR risks and obligations,” Gough says.

“Our overall mission is to help play a part in eliminating construction waste by repurposing the materials back into the industry, as Angar Environmental is focused on building a cleaner future for the environment.”

Angar Environmental’s innovative full recycling process of clean mud slurry waste is a significant step forward for the construction industry. “Our commitment is to build a cleaner future for the environment by repurposing materials back into the industry,” McIntosh says.

“As we continue to expand our operations and collaborate with other recycling groups, we continue towards a greener and more sustainable future for all of us,” Gough says.

Maxibor breaks through climate transition challenges

As the civil construction sector is going through the post–pandemic recovery stage, it needs to manage other challenges, namely climate transition, labour shortages, supply chain disruptions and inflation. Maxibor CEO Rodney O’Meley shares his insights on the impact of these challenges on the horizontal directional drilling industry and how Maxibor is addressing them so that clients and other project stakeholders’ expectations continue to be met.

O’Meley is adamant: the horizontal directional drilling (HDD) industry must play a big role in the climate transition process.

“Maxibor has been at the forefront in Australia for some time now as we have espoused the important contribution the HDD industry can make to mitigating the impact of increasing frequency and impact of fire, wind, flood, inundation, sea level rise, subsidence, drought and rain rivers and rain bombs,” he says.

“It is ever more important that the diffusion of new knowledge and better practice around HDD is promoted across the infrastructure sector as the impact of climate change is accelerating much faster than expected and becoming even more extreme.

“The Maxibor cooperative and knowledge sharing approach across the trenchless industry is the way we can build a future we all look forward to.”

The company’s status in the HDD industry allows it to self-perform most projects with its highly experienced drillers and crews. The volume of HDD work now and in the pipeline is however placing significant pressure on resources in Maxibor and across the HDD industry.

“Maxibor is needing to work smarter and more productively to help overcome the scarcity of labour resources,” says O’Meley.

“It is also supplementing its existing resources through both subcontracting and assembling project teams from the body of contract HDD workers in Australia and abroad.”

Maxibor has already been able to improve its productivity in several ways.

It’s the case for when it comes to continuing the push for early involvement in the design of projects utilising the better practice knowledge that exists inside Maxibor and its wider network of design engineering and other advisors. This expedites project start times and minimises delays through the delivery stage.

The company has also improved the enhancement of in-field technology for daily reporting, data gathering, security and site inspections (drones) along with application of advances in design engineering, business development and operational management technology. The digital dividend is time and money saved and more informed decision making.

Maxibor extended one of its Vermeer 100x120 rigs to enable it to use the longer 9.1 metre drill rods providing maxi-rig drill rod capability without increasing the set-up area.

The company also focuses on the individuals who are part of the brand’s DNA; Maxibor focusses on on-going people skill development as part of a life-long learning approach, and creating a more agile workforce and increased role flexibility within the company.

Maxibor has implemented a successful subcontractor model.

“Clients are very happy as Maxibor maintains its full involvement in the important early design and scoping stages of the works,” says O’Meley.

“Subcontractors are happy as they have access

to a ready pipeline of work without the hassles of business development, commercial negotiations, dealing with the client on delivery matters and preparation and collection of payment claims.”

This approach, combined with on-going HDD project management through Maxibor’s experienced and knowledgeable project managers, ensures works are delivered safely, with quality and on schedule.

“Our clients know that Maxibor will be there at all the key phases of the project and are happy in dealing with an HDD provider who knows how to work cooperatively and share knowledge across the supply chain to get projects delivered,” he says.

“Subcontractors are happy as Maxibor effectively takes away their pain points and allows them to move to the next Maxibor provided project without the concern or cost of all the areas which Maxibor’s very experienced design engineering and HDD project management team very capably handle.”

The company already has numerous subcontractors working under this model, and there is growing interest from others looking to reduce the pain.

“Subcontractors are also appreciating the support Maxibor provides them through access to equipment, friendly cash flow and support for them to develop and grow in their own right,” says O’Meley.

According to David Turner, Maxibor’s National Business Development Manager, its reputation and network across the Australian and international HDD world is due to its numerous skilled HDD drillers and crew members who can be readily assembled for those special projects requiring added and experienced resources to undertake delivery of the works.

“The ability of Maxibor to be able to bring together a very experienced additional team at relatively short notice is helping Maxibor to participate in even more major maxi-rig projects,” says Turner.

“Clients are very impressed when you can turn up with such experienced heads in your HDD project team.”

Supply chain disruption has been one of the major side effects of the global health and political upheaval in the past few years. This has particularly impacted the supply of specialised equipment into the civil construction sector.

Maxibor Extended Vermeer 100x120 drill rig.

Maxibor is overcoming this situation through improved supply chain management processes as the company is constantly working with suppliers to ensure that supply of materials and other services into projects is able to be aligned with the construction schedule.

Strong supplier relationships developed over many years is being leveraged to ensure project needs are met in these difficult times.

Maxibor is also working closely with international supply chain experts such as Alex Tao from AusInland, who can better connect Maxibor with overseas sources of equipment not readily available to the Australian market.

This is increasing Maxibor’s knowledge of the latest technology and innovation in the underground installation industry and opening wider opportunities of participation in the market.

One of the other challenges the HDD industry has to navigate through is inflation.

It is an increasingly significant factor in the pricing of projects, as the time from initial quote for a project to actual delivery now very much matters given the underlying rate of inflation.

O’Meley says the civil construction sector has been particularly impacted by increases in fuel, equipment costs, interest rates and insurances.

While the average wage growth rate at around 3.8 per cent is lagging inflation, it is expected to escalate further in 2023, especially in the

civil construction sector where job vacancies are very high.

The wage growth rate for the sector is likely to be above the expected 4.5 per cent average for Australia by the end of 2023, even if the headline inflation rate falls.

The annual inflation rate in Australia climbed to 7.8 per cent in Q4 of 2022, well above the low 2s and 3s in recent years.

“With the lags from pricing to delivery on many HDD projects being in the range of six to 12 months, the need to carefully consider both initial pricing and a final negotiated price becomes much more critical since margins on thinly priced projects can be quickly eroded through delays,” O’Meley says.

He says that “mechanisms need to be in place to ensure projects are being completed for a fair and reasonable price, not one that will impact

the sustainability of the business”.

Some of the initiatives Maxibor has taken to mitigate the inflation factor include four pillars. The first is seeking to work with asset owners and principal contractors to help to accelerate design approvals to facilitate earlier commencement of works.

It’s also primordial to gain pre-contract approval for ordering materials to lock-in price and secure supply. Revisiting designs with the benefit of additional geotechnical information and site understanding to help reduce project cost and risk is also a sine-qua-non condition for success for Maxibor.

O’Meley says this is coupled with revisiting the construction schedule to bring forward parts of the scope ready to go, and providing more time for those sections requiring a longer approval period.

IMPREG continues to invest in Australian and NZ market

In February this year, a small team consisting of APAC General Manager, Michael Ellenrieder, new IMPREG Australia and New Zealand Country Manager, Colin Murphy, a Senior IMPREG installation technician as well as a UV equipment specialist drove from Brisbane all the way down to Melbourne to make site visits at various projects and key accounts along the way.

The four visited various sites along Australian’s East Coast to introduce Colin Murphy as the new point of contact for Australian and New Zealand-based customers as well have a Senior Technician providing some brief training on IMPREG‘s liner and its advantages.

It was shared that a technician will also join the team based in Australia in May to ensure a smooth process through projects from start to finish.

The technician from the United Kingdom has over 15 years of pipe installation experience and will be deployed to clients’ sites for technical assistance.

The tour, that was spread over a couple of weeks, had various stops along the way to show new prototypes and systems to key accounts as well as sharing insights into current developments within the industry. Murphy outlined how productive the tour had been.

“The trip was a great success, team IMPREG

everyone we visited, if time allowed, we would have kept going,” he says. “It’s a real pleasure to be part of such a technically advanced team.”

Another focus for IMPREG Australia this year is to streamline the distribution for Australia and New Zealand by placing stock in New South Wales and Auckland.

Murphy says by having stock closer to Sydney will improve distribution across Australia, and the Auckland stock will serve the whole of New Zealand.

IMPREG is working with industry experts to ensure a smooth transition and the least disruption for customers as possible.

IMPREG’s dedicated technicians always ensure every rehabilitation project goes smoothly.

Aussie Trenchless is at the cutting edge of keeping infrastructure safe, secure, and operational for as long as possible. It’s why its products ensure minimal disruption and maximum benefit.

Aussie Trenchless Director Chris Meredith and the team are committed to pioneering state-ofthe-art solutions and furthering business in the trenchless industry. As part of that innovation, the company continually offers a wide range of unique products in Australia and globally.

Aussie Trenchless SRP-EXP Spiral Lining System is designed to rehabilitate pipes from DN150 to DN1200 using six different-sized profiles. The SRP-EXP system is a closefitting structural spiral ribbed PVC trenchless pipelining system.

What is spiral wound lining?

Spiral wound lining is a trenchless technology that uses a continuous plastic strip to form liners in gravity pipelines. Meredith says this unique rehabilitation method originated in the 1980s. With four decades of installation history, the spiral wound has been used extensively on pipes across the globe. Like cured-in-place piping (CIPP) or slip lining, spiral wound liners provide a structural lining solution for fully deteriorated pipelines with minimal site disruption.

“Aussie Trenchless stands out from its competitors by providing all contractors access to spiral ribbed lining,” Meredith says.

A liner pipe is formed inside the host pipe by helically winding a PVC profile strip into a host pipe, usually from an existing access chamber.

The winding machine is initially set to a smaller diameter than the host pipe. As the profile is continuously fed into the winding

machine, the lead end of the PVC Ribbed Pipe rotates as it is wound into the host pipe.

The SRP-EXP pipe will ride over displaced joints and negotiate slight bends and damaged areas. When it gets to the other end of the host pipe, the SRP-EXP is made to expand in diameter until it is in close contact with the internal surface of the existing pipe.

The result is a new PVC pipe within the damaged pipe without excavation.

What is the SRP-EXP Spiral Lining System?

The SRP-EXP System is a close-fitting, structural spiral ribbed PVC trenchless pipe lining system. The winding machine is positioned in an access chamber or pit. It then helically winds the SRP-EXP ribbed strip to

first installed at a smaller diameter and then expanded to be a close fit against the internal surface of the existing pipe.

The SRP-EXP profile strip has a dualaction lock. During the initial wind-in process, this holds the spiral wound pipe tight at the smaller diameter.

When the far end of the installation length is reached, the SRP-EXP Liner end is restrained. The lock area is sequentially released so the liner can expand in a controlled manner until it is pressed hard against the inside wall of the existing pipe.

Benefits of spiral wound lining

Why have spiral wound linings become so successful in this market? What are the main benefits to the installer and client?

The SRP-EXP system is capable of negotiating displacement and slight bends while also maintaining a relatively small site footprint.

Aussie Trenchless believes repairs using traditional civil open cut methods are far too costly and disruptive on communities.

to-weight ratio. That means less material is needed, making it a more cost-effective solution. With a high strength-to-weight ratio, the SRP-EXP System can handle a variety of pipe diameters, circular or otherwise.

Spiral wound lining can be installed while liquids flow through pipes without bypassing the flow. It can be deployed in numerous situations without disrupting people’s lives. By locking strips of lining together, the installation process is entirely mechanical. There is no need for any curing or heating to prepare the lining for the pipe. This is an enormous advantage, particularly given the tight-fitting nature of this lining solution.

When looking at any infrastructure project, a key component is managing the community impacted by the works. Spiral wound lining installations tend to have small site footprints and minimise resident disruptions. They also feature minimal wastage, as the contractors on site only need to use as much product as necessary. Any wastage that is generated can be recycled with ease.

The SRP-EXP System is designed to last for at least 50 years. Such longevity can dramatically reduce maintenance costs for water authorities and local councils. It provides more options for customers to use their limited financial resources over the long

term, thereby improving outcomes for all involved.

Where to now with spiral wound lining?

Over the past 25 years, advances have extended spiral wound linings’ capabilities to larger sizes and greater load-carrying capacities. It has repeatedly been proven capable of renewing deteriorated sewers, storm drains and culverts. It can be utilised in applications where rehabilitation by lining would otherwise have been impossible.

Latest advances have seen many of the limitations of these liners overcome. It continues to extend the possibilities for structural rehabilitation of an ever-widening range of deteriorated conduit configurations under a broad range of conditions.

Investment is being made in further research and development. These results should see the possibilities for further trenchless structural pipeline rehabilitation. As with past advances, development is taking place with the support of Australian and New Zealand water authorities. They have always encouraged such development.

“It represents a willingness to incorporate innovative solutions that can be seen to offer mutual benefits,” says Meredith.

Trenchless contractor puts maintenance hole relining system through its paces

M. Tucker & Sons has rehabilitated a number of maintenance holes in southeast Melbourne. The company used the Brandenburger’s BBS.8 maintenance hole liner – which it has exclusive installation rights to in Victoria, South Australia and Tasmania – combined with a Rausch Rehab UV curing system, and managed all aspects of the installations including traffic management.

M. Tucker & Sons is a family-owned civil and trenchless drainage specialist with more than 30 years experience in civil and trenchless rehabilitation, the company has a track record for delivering high quality pipe rehabilitation, asset management, relining and drain cleaning projects and is repeatedly called on in situations of high technical difficulty.

In 2022, the contractor added Brandenburger’s maintenance hole relining system, BBS.8, to its suite of trenchless solutions, securing the exclusive installation rights to the product in its home state of Victoria, as well as South Australia and Tasmania. The addition of BBS.8 to its existing toolbox of trenchless solutions means that, in conjunction with UV GRP mainline liners, M. Tucker & Sons can supply a structural rehabilitation solution for an entire sewer system.

The company has recently been putting the product through its paces, with teams renovating aging stormwater maintenance access infrastructure on the outskirts of Melbourne. The company managed all aspects of the work as well as supporting services, such as preparatory and installation teams, high pressure cleaning, traffic guidance scheme

design and the Memorandum of Authorisation required by VicRoads.

M. Tucker & Sons managing director Brendan Tucker says the company is proud to be at the forefront of this exciting trenchless technology.

“Sewer maintenance hole rehabilitation

is becoming more and more known to be considered for trenchless rehabilitation,” he

“We have also been assisting stormwater network owners with rehabilitation on some access structures in areas or environments that would be problematic to excavate and reconstruct. We are exited to have this system added to our existing range of services on offer for the maintenance or renewal of sewer and stormwater infrastructure.”

BBS.8 is the world’s first UV maintenance hole liner with the capacity to adapt to the shape of the asset, using only air pressure, without the need to pre-measure or laser scan the asset prior. This eliminates the time required to measure the dimensions inside the structure, ultimately reducing the cost of the rehabilitation project and lead time involved in planning.

With specific installations procedures, BBS.8 is able to rehabilitate the chosen asset entirely including the bench, chamber, taper and neck in one homogenous liner, free of joints or stitching.

Focus on pipe protection

kwik-ZIP centraliser and spacer systems are solving challenges in trenchless pipe installations across Australia and worldwide.

Late in 2022, Sydney Water and the West Region Delivery Team (WRDT) contracted Quickway for a water mains installation project. Quickway specialises in transport and utility infrastructure, having completed many projects around Australia. The project was centred on Elizabeth Drive in Badgerys Creek, a western Sydney suburb. The water main needed slip-lining of an 813 mm outer diameter (mm OD) carrier pipe.

Quickway utilised kwik-ZIP HDX-90 spacers to facilitate the slip-lining over a 180-metre run. The spacers were installed two metres apart along the length of the pipe, following Sydney Water specifications.

When empty, the pipe weighs 240 kilograms per metre and about 700 kilograms per metre when in service.

“kwik-ZIP spacers provided both protection and cover for the carrier pipe. It allowed us to complete a successful underbore installation,” says Quickway project engineer Matthew Macinnes.

What is the HDX Series?

The HDX Series has a unique load-sharing design. It is designed to maximise the loadbearing capacity of each runner while reducing point loading. The simple and efficient installation process does not require any special tools.

The HDX casing spacer comes in four runner heights, ensuring that pipeline installers can handle a range of carrier pipe outer diameter and casing inner diameter combinations. This flexibility grants installers the ability to customise pipe position for grade control.

Jason Linaker is the Managing Director and creator of the Australian-owned kwik-ZIP products. He is proud to have multiple WSA PS-324-compliant in the HDXT and HDX

series. The recognition of these products will allow kwik-ZIP to continue supporting safer and longer-lasting installations.

“kwik-ZIP casing spacers will protect pipes, make installation easier and extend the life of your asset. With two product series being approved by the industry, choosing the right spacer for longevity and success is easy,” says Linaker.

The spacers incorporate low friction, high abrasion-resistant wear pads attached to load-sharing runners. The outside diameter of the pipe determines the number of segments required for each spacer.

“Flexibility of the design means various runner heights across the series of products can be achieved. It allows for different pipe/casing combinations and a broad range of carrier pipe dimensions,” says Linaker.

“Spacers are usually a small part of the overall pipe installation process. Correctly designed

and fitted non-metallic spacers with low friction runners can increase the life expectancy of the pipeline. They mitigate corrosion, protect pipes from abrasion and scoring during insertion, and reduce installation forces on joints during slip

The different runner heights across the HDX and HDXT models ensure pipeline installers can handle a range of carrier pipe OD and casing host pipe ID combinations. It also allows installers to custom-pipe position for grade

What is unique about kwik-ZIP?

kwik-ZIP’s series of spacers caters to a range of carrier and casing pipe size combinations. It also provides contractors and installers flexibility to deal with project alterations.

kwik-ZIP spacers have no metal parts, instead manufactured from high-grade thermoplastic. It is flexible and tough, and the low-friction coefficient also minimises the installation forces for large bore pipes.

The metal-free construction is compatible with all potable water applications and is resistant to corrosion and rust.

kwik-ZIP’s HDX Series further minimises potential damaging vibration and movement transfers from the outer casing to the carrier pipe via innovative suspension and dampening technologies.

The kwik-ZIP systems are now used in production well completion, horizontal directional drilling (HDD), rock bolt and anchor centralisation and trenchless pipeline installations across Australia, New Zealand, the UK, and the US.

Drain inspection cameras available for distribution in Australia

Founded in 1978, RICO first developed technology for testing welding seams of pipes, laser devices for measuring distances, and cameras for nuclear plants. RICO later focused on TV inspection of pipes and sewers.

In 1990, the company was sold to the ROTHENBERGER Group, residing in Kelkheim, Germany, before merging with the EAB, Kleinwalsertal, and later with RICO in Kempten in 1994.

As a result, this created a company - strong in development, and able to operate worldwide.

Today, ROTHENBERGER, with its flexibility and responsiveness, share-owning management, and financial power, deriving from the group-membership, has a special position among its competitors.

With a range of products on offer through the German manufacturer, RICO offers different types of cameras to assist the trenchless industry.

ROTHENBERGER Australia and New Zealand Managing Director Trent Carter says RICO offers specialised inspection cameras designed for some of the toughest conditions and applications.

“These cameras come with many standard features such as LED lighting, self-levelling camera heads, pan and tilt functions, and highresolution video recording capabilities,” he says.

“In addition, RICO offers a range of inspection systems that include monitors, recording devices, and other accessories that are used in conjunction with the cameras.” As well as the addition of WinCan™ smart sewer technology software.

The use of RICO’s cameras, operators can quickly identify issues such as cracks, blockages, or other damage, and make informed decisions about the best course of action

“This ultimately saves time and money while improving the overall quality of service provided

RICO is on the hunt for multiple distributors in Australia for the company’s range of inspection cameras and systems for the trenchless industry.

to customers,” Carter says.

Throughout RICOs extensive experience and knowledge, their cameras are commonly used in industrial and commercial pipes inspections to visually inspect the condition of pipes and identify any defects or damage that may require repair or maintenance.

The range of offer is at the high end and predominantly is the crawler type camera, which is designed to traverse through larger diameter pipelines.

Carter says these cameras are often used for longer inspection runs in larger diameter pipes and can navigate easily through bends and turns.

“RICO crawler cameras while typically have standard features, such as the ability to pan, tilt, and zoom the camera and may also be equipped with laser scanning capabilities for capturing 3D information about the pipe’s interior,” he says.

“Both RICO push and crawler cameras are capable of capturing high-quality videos and images of the pipe’s interior and can be used to detect defects such as cracks, corrosion, or blockages. However, the choice between a push camera and crawler camera will depend on the specific requirements of the inspection, such as size and configuration of the pipe, the length of the inspection run and the desired level of detail and accuracy.”

Adding to RICOs extensive range is laser scans. Laser scanning is another useful tool for trenchless operators when inspecting drainpipes as it allows for the capture of 3D information

about the interior of the pipe.

RICOs laser scanner on its cameras can quickly and accurately measure the distance to points on the surface of the pipe, creating a detailed 3D point cloud of the pipe’s interior.

This 3D information can be used to detect defects such as cracks or corrosion in the pipe’s surface that may not be visible to the naked eye or with traditional video inspection methods. The 3D model can also help to identify the location and size of defects, which can aid in planning repairs or replacement of the pipe.

“Overall, using a RICO camera with laser scanning capabilities can help to provide a more accurate and detailed

inspection of pipes, potentially leading to more efficient and effective maintenance and repair efforts,” says Carter. “As a ROTHENBERGER Group member, RICO receives financial backing for development of the newest technologies and support from our company too.”

Drain Tech Australia is an industry leader in pipe management services and technology. It remains at the forefront of CCTV pipe and conduit surveying with innovative equipment, specialising in a vast array of pipe services, structural pipe inspections and the latest stateof-the-art technology. Drain Tech Australia utilises the latest Wincan software, which adheres to all council, industry and WSAA reporting codes and standards.

With its experienced and qualified team boasting decades of industry experience, Drain Tech Australia can complete any job safely within strict deadlines. It emphasises the importance of safety on our job sites and ensures the best industry practices.

Drain Tech Australia supplies its clients with a better and more cost-effective solution by implementing many different cost-saving initiatives throughout our business.

What products does Drain Tech Australia use?

Drain Tech Australia uses state-of-the-art robotic Rausch CCTV cameras with robust pan and tilt technology. It allows them to thoroughly inspect any pipe’s structural integrity and serviceability ranging from 100 mm to >2100 mm.

For smaller diameter pipes (50 mm100 mm), Drain Tech Australia can utilise its remote battery-powered push camera inspection system. This remote system can be set up in even the most difficult-to-access places, for the top of a building, the middle of the bushland, or a factory or small office.

Steven Gall founded Drain Tech Australia 12 years ago. In his opinion, the industry needs to invest more in new equipment.

“No one was willing to put their hand in their pocket and invest in anything new. The cameras were getting tired and old. With technology moving so quickly, I put my hand in my pocket and decided to take everybody on,” he says.

When talking about the Rausch CCTV

cameras, Gall has found that Rausch is willing to invest in research and development to improve their cameras.

“Some companies out there have not changed their hardware in over 15 years,” Gall says. “Rausch, on the other hand, has significantly improved their cameras. While our clients might not see that on-site, it allows us to do things that we otherwise would not be able to do.”

Gall spoke about the technology available for small-diameter pipes. Most cameras sit centrally in the pipe and cannot adjust to the water levels within a pipe. However, the Rausch systems have an integrated lift, allowing the camera to move within the pipe and increasing the total field of view where necessary.

Working with Austeck

Drain Tech Australia has a long partnership with Austeck, a wholly Australian-owned company. Founded in 1992, Austeck has established itself as a market leader in confined space robotics. It is now one of the largest and most experienced supply and support companies for pipeline inspection and rehabilitation in the Australasian region.

“We have a great relationship with Austeck,” says Gall. “We’re on the same page regarding getting the Rausch products we

Future of the industry

When looking into the crystal ball, Gall

“The increased quality of cameras is creating larger files. We need to move those files around, and while we live in a streaming world, it doesn’t quite work like that when dealing with water authorities or local government. You might be able to download a large chunk of data in seconds on your home computer, but that is not the case when dealing with organisations with extensive processes for inserting data into their servers,” he says.

While artificial intelligence (AI) is an emerging issue within the industry, it is not something that Gall is focusing on at this point. He acknowledges that it could eliminate much of the guesswork and inconsistent interpretation of information. However, working out how to interpret data is a skill in its own right, and doing so reliably will require significant resources.

“I’ve not heard of any council or water authority working on it. The systems are not flagging or seeking a review of something through a notification by AI, at least not from any council I know of. We must be aware of this technology and development, ready for it as an industry.”

OptionX Group strikes deal with MTS Microtunnelling Systems

OptionX Group has expanded its offering to the drilling, tunnelling and boring industries by entering an agency agreement with the German company MTS Microtunnelling Systems. This agreement will see OptionX Group become the exclusive seller of MTS equipment across Australia and New Zealand.

Along with selling the sought-after machines, OptionX Group will offer after-sales support and service for MTS, and stock critical parts for urgent repairs.

Bournedrill, one of the businesses within OptionX Group, is well-placed to support MTS equipment, having designed and manufactured drilling, boring and tunnelling equipment for almost 60 years.

This level of service is rarely seen in Australia, with repairs on machines like this often calling for imported parts or mechanical experts to be flown in from overseas.

OptionX Group CEO, Stuart Harrison, says the industry has been crying out for more efficient local service.

“There is an abundance of tunnelling work available in Australia at the moment, but often delays are caused by inadequate equipment or waiting for parts to arrive from overseas,” says Harrison.

“The goal of OptionX Group has always been to create more options for the industry, and this deal with MTS is just another solution we can now offer.”

MTS Microtunnelling Systems has a strong reputation around the world and utilises the very best of German engineering. OptionX Group’s Business Development lead, Jim Perry, says he expects the MTS machines to sell well in local conditions.

“The MTS products have proven themselves around the world. The high praise we often see for German engineering is well deserved, and the quality of MTS machines is exactly what you would expect from Germany,” says Perry.

Perry is also the Managing Director of Tunnelcorp and says the backup support from OptionX Group will be a game changer.

“Even the best equipment is subject to wear and tear, so being able to service machines appropriately and replace parts as required will extend the life of the equipment. This in turn will reduce delays and stoppages, which is an attractive option to contractors and asset owners alike,” he says.

“In Australia, it’s often complicated to source replacement parts and complete repairs. Having access to Bournedrill’s workshop and

engineers means parts can be supplied when they are needed.”

As the founder of Edge Underground, Australia’s leading microtunnelling contractor specialising in sewer and water pipeline installations, Harrison also knows how important it is to work with reliable machinery.

“MTS machines have a proven track record worldwide, and I’m excited we can now offer these machines to the Australian and New Zealand markets. These machines are built to handle ground conditions from soft formations below the water table to the hardest rock, but can also be used in other ground conditions,”

Another recent expansion of OptionX Group is the creation of PerforatorX, a joint venture between OptionX Group and German

Progress is in the pipeline: shifting the dial towards a more inclusive industry

In 2023, construction remains the most male-dominated sector in Australia, with female participation at just 13 per cent. Attracting more women to the industry could be part of the solution to the crippling skills shortages the broader sector is facing. How then, do we build workplaces that are attractive to everyone and that women can thrive in?

Across Australia, women remain an untapped talent pool. In construction, only 2 per cent of women working within the sector are in trades.

There is a push within Governments and industry bodies to improve the numbers. The National Association of Women in Construction, for example, has set a goal of 25 per cent female participation by 2025.

This trend can be seen throughout the water sector, too. Shifting values within urban water businesses has led to an increased focus on diversity and inclusion. Gender equity is recognised as a meaningful way to foster better outcomes for workers, customers, and the community.

Across the sector, authorities and councils are putting ‘gender on the tender’, asking contractors and suppliers to meet a minimum standard of policies, plans and targets. The Victorian Government is leading the way with gender mandates for publicly funded projects of $20 million or more.

Targets and quotas play an important role in keeping diversity on the agenda and encouraging

women through the door. The other piece of the puzzle is creating an inclusive environment that enables women to stay in a business or sector once they arrive.

Tracy Keevers, the Executive Manager of People & Capability at leading pipeline infrastructure company, Interflow, shares her insight.

“True inclusion means removing the barriers preventing women from entering, staying in and thriving in a sector or an organisation,” she says.

“The barriers might come from a poor internal culture or a negative public perception of a particular industry, but they can be practical, too. We need to consider everything from the behaviours and capability of leaders right down to making sure uniform policies are inclusive and the right facilities are available to people.”

Behaviour-led culture change

Construction is perhaps the most maledominated industry in the country. This has been the case for many generations, leading to outdated masculine ways of working that can make women feel unwelcome.

The sector has come a long way in recent years, but there is still work to be done to rid workplaces of exclusive behaviours. Communicating the broader benefits of structural and cultural change, for men and women, is part of the solution. Another is equipping people with tools to recognise biases and check attitudes that undermine an inclusive culture.

“Having policies in place that promote respect at work is a great first step,” says Keevers. “Just as important is giving people the tools and training to be the best versions of themselves at work and at home.”

“We’ve had a lot of success with positive behaviour-focussed programs and language. This gives our people the confidence to respectfully call out what we call ‘below the waterline’ behaviour, knowing that they will be supported by the business for doing so.”

Making choices visible

If greater diversity in the industry is the key to building a stronger industry, how then do we attract more women in the first place?

Interflow is encouraging other women to join the industry.

Talent Acquisition Business Partner Daniella Saumatua.

One part of the solution is encouraging young women to join the industry or learn a trade from an early age. Perceptions of a sector or career, whether valid or mistaken, can be formed at an early age and influence decisions later in life.

A study has shown that school-aged girls aren’t aware of the opportunities the industry presents and can’t picture themselves in the job. This, coupled with a lack of visible role models, means that working in construction simply isn’t on the radar for many school-aged girls.

While there are programs in place to encourage young women into STEM fields, there isn’t always visibility of the opportunities available to them within the construction sector.

Interflow’s Talent Acquisition Business Partner, Daniella Saumatua, says the opportunities for women in the construction and utility sectors are abundant.

“We have women in the field and on the tools, leading crews, and working as engineers,” she says. “We also have women in roles that are highly transferable between sectors, like in our people team, finance, safety and quality, marketing, IT, community relations, business development – you name it.

“The scale and variety within the sector mean that people can choose their own path and shape their career to suit their interests and expertise.”

Removing the barriers to entry

Long hours, rigid work practices, and everchanging job locations have long been associated with the construction sector. While these factors disadvantage everyone, they can exclude people with caring responsibilities, most often women.

Now, with a growing trend towards flexible work options, paid parental leave for all parents, a push towards a five-day work week, and a growing focus on wellbeing, the industry is becoming more attractive to everyone.

Flexible working arrangements, like those provided by Interflow, are enabling more women to return to work after taking parental leave.

Interflow’s Georgina Hilder, Community Relations Manager, had her second child while working at Interflow and is currently on parental leave.

“Knowing there are flexible options available means I don’t feel like I need to choose between my career and my family,” says Hilder.

“When women have the reassurance that they can balance a fulfilling career with their personal lives, they’re going to be more likely to return after taking time off to start a family.”

Inclusion begins with the hiring process

While platforms like WORK180 are helping women make informed choices about who they work for, the hiring experience starts and ends with the organisation.

One way to support inclusive hiring practices is to uplift the capabilities of hiring managers. Honing interview skills and teaching leaders how to recognise their biases can open the door to a more diverse range of candidates.

Other ways include making sure your selection processes clear and transparent, writing compelling job ads that outline policies like flexible work options, and focussing on transferable skills.

“We’re shifting the conversation from ‘who is most qualified for the job?’ to ‘who is best for the team, who will add to the culture and bring new ideas?’” Saumatua says.

“There are so many fulfilling opportunities within the construction and water sectors. When we work together to break down the barriers to entry, we’re giving women a chance to build a brighter future for themselves and their communities.”

How to clean large diameter pipes full of water and debris

AquaTeq’s longstanding experience developing and producing different types of ejectors has helped the company develop a cleaning nozzle equipped to service the trenchless industry.

Drainchem Australia is the exclusive supplier of AquaTeq’s ejector nozzles, and understanding that they are designed with a patented tube, system to manage the water flow very efficiently. The jet inserts are mounted inside the tube, allowing the ejector nozzle to utilise existing water in the pipe to increase effective flow rates by a factor of 10.

In combination with the water supplied by the jetting truck, this will increase the velocity and volume of the water in pipe, making the Sweagle highly effective in both dry and flooded pipes.

The team at AquaTeq say the ejector nozzles

are very effective, but since the jets are located inside the tube and with an almost straight rear facing angle, the waterjets will in most cases not reach the sides of the pipe and may create a trench in the debris.

That is why Aquateq has introduced the SWEAGLE®, which is designed and developed to overcome most challenges in the pipe cleaning industry using AquaTeq’s experiences and know-how.

With a patent pending built-in ejectors system, the SWEAGLE, in combination with AquaTeq’s advanced water-conducting tube water-directing system, the water jet is now

positioned inside each ejector.

Together with the flow-oriented construction of the ejector, the ejector nozzle increases the water velocity in the sewage or stormwater pipe and is able to shift the material more efficiently.

The SWEAGLE is designed to work with both fresh water and recycled jetting water. It utilises the water in sewage and stormwater pipes to effectively move debris in the pipe at as low working pressure as 35 Bar (500PSI) at the nozzle.

The SWEAGLE sucks the water from the pipe up to 10–times the flow rate of pump on your jet truck.

The Swegle jetting water in a pipe with debri.

Sweagle in pipe with debri.

In a test of the SWEAGLE, the highpressure pump supplied 200 LPM at 40 bars (600 PSI) pressure at the nozzle. The SWEAGLE was placed in a 600 mm pipe and ejected 2500 LPM of water. That is 2300 litres per minute more than the pump flow rate.

As a result, AquaTeq has been able to identify that in pipes where the water level is high, the ejectors create an extreme negative pressure, utilising the water in the pipe in combination with the water supplied from the jetting truck.

This means it is dramatically increasing the volume of water cleaning the pipe, compared with only using the water supplied from the high-pressure pump. SWEAGLE also performs efficiently in dry pipes at a very low operating pressure.

Not only does is this ejector nozzle more efficient, but it also provides operators with savings regarding water, fuel consumption, along with wear on jetting truck, and a reduction in work hours spent on site.

For optimal cleaning effect (cleaning a pipe in the shortest time with minimal water and fuel consumption), the pressure the SWEAGLE should be set to is a maximum of 60 Bar (900 PSI) when pulling back the nozzle.

When the nozzle is transported upstream, higher pressure may be required depending on

the slope of the line. However, the SWEAGLE works efficiently at an operating pressure of 30 bar (400 PSI) at the nozzle.

The SWEAGLE is supplied with a front sieve acting as a coarse filter, minimising the risk of ejectors being clogged internally. The sieve can easily be removed and cleaned, with the design of the nozzle body, in combination with the sieve assure, the full ejector can function up to

Directionally drilling down, down, down

The evolution of HDD continues with the Ditch Witch JT24

Directional Drill. It is designed to give customers the power and footprint to be the ultimate uptime champion.

Two years ago, CEA became the Australian and New Zealand distributor

provides 101 horsepower, 3000 ft-lbs of torque and 24,000 lbs of thrust and pullback at a size that easily fits in tight job sites. Plus, its low centre of gravity gives operators more stability than competitive units so that contractors can work with confidence.

Best in class and modern design

The compact and powerful JT24 offers best-in-class stability and modern design for easy use in congested urban and residential job sites.

Equipped with a tier 4- and European Stage V-compliant Cummins diesel engine, the JT24 packs a punch with unbeatable power. Its powerful thrust and pullback are packed into a small footprint, offering outstanding performance on various utility installations. A new hydraulic platform utilises leading technology to maximise drilling efficiency and conserve horsepower for where it matters most - downhole.

“We continue to evolve our directional drill offerings to provide more efficient and productive modern solutions to meet the growing underground challenges facing today’s HDD contractors,” says Scott O’Hare, Ditch Witch’s National Product Manager.

“The JT24 was designed based on direct

customer feedback,” says O’Hare. “It is manufactured to effectively manoeuvre and traverse urban terrains where much of the utility and rehabilitation work is happening today. All without compromising the power to complete the job on time and budget.”

The JT24 is designed with a wider frame than competitive units, offering best-in-class stability without sacrificing manoeuvrability in tight urban environments. Users can confidently traverse uneven terrain, city curbs and other challenging terrain situations. Its small footprint means it can easily be towed from one job site to another.

What makes this downhole drill distinctive?

directional drill fills the gap between the company’s JT20 and JT25 drills. It aims at the fibre optic, gas, and water installation market, and is launching this year in Australia after operating successfully in the United States and Europe since late 2019.

Corey Maker, Manager of Product Marketing at Ditch Witch, says it has 20 per cent more stability on this machine.

“The track assembly is similar to the JT25. We know that users will get into situations where getting that lower centre of gravity is a big deal,” he says.

According to Ditch Witch, a new hydraulic platform maximises drilling efficiency and conserves horsepower for downhole operation. An 83-decibel noise level helps operations in noise-sensitive areas. The 66-metres-per-minute maximum carriage speed is designed to decrease cycle times.

“The cruise control is pressure compensated,” says Maker. “You set the pressures, and you maintain whatever feet per minute you’re using going up and down the carriage. Once it drills out the rod, it returns to the rod change position. You’re ready to go through the making/breaking pipe cycle.”

The drill has 122 metres of pipe on board. It has a removable pipe box, so another can be added after an operator drills 122 metres. A Subsite locator display is integrated into

the drill operator’s display. The JT24 also has an advanced wireless remote, which allows users to run the ground drive and set up features.

“That allows you to get onto the job site and get into position much faster,”

Guiding through technology

For over 40 years Vector Magnetics’ technology has been at the forefront of the underground construction industry’s most challenging sub-surface navigation problems.

Owners of medium to large horizontal directional drilling (HDD) rigs across the globe have grown to trust ParaTrack technology to deliver rugged and reliable guidance regardless of ground conditions. Designed and manufactured by Vector Magnetics in the United States, ParaTrack is available to Australasian customers through Prime Horizontal and Inrock.

ParaTrack traces its lineage to technology Vector Magnetics originally developed for the oil and gas sector.

In 1980, it invented the first magnetic ranging system capable of reliably locating installed well casing by detecting its magnetic signature. This made it practical to drill relief wells to plug a blowing out or leaking well bore when direct access to the surface casing was impossible.

The technology was commercialized as the WellSpot relief well guidance tool. Now owned and operated by Halliburton, WellSpot remains the dominant relief well guidance system available.

A long-term commitment

Today, Vector Magnetics’ focus is primarily on the manufacturing and support of its ParaTrack HDD Guidance System.

The ParaTrack line-up has continually expanded, and now offers a wide range of guidance technology at a variety of budgets. ParaTrack is available as a complete guidance service from Vector Magnetics’ distributors,

and most customers will have their first exposure to ParaTrack in this way. However, ParaTrack equipment may also be purchased by rig owners who want to bring their guidance in-house.

Marketing and Operations Manager Jed Sheckler says ParaTrack delivers cost-effective, highly accurate guidance that is effective for HDD projects of all sizes.

“A customer may start with a base kit consisting of a Steering Tool and ParaTrack2 (P2) AC Guidance system,” he says.

“The kit is fully modular, allowing an owner to build upon their initial investment, adding tools as they expand their capabilities. For example, once a customer has success guiding a few bores with a base kit, they may take the opportunity to tackle more complicated

ParaTrack Guidance was provided through Prime Horizontal for a power installation project in Melbourne.

jobs. Through their distributor relationship they’ll have access to tools like the Gyro, At-Bit Inclination Assembly (ABIA), and Beacon Tracker, giving them flexibility to successfully bid and complete a wider variety of installations.”

Vector Magnetics’ customer relationships are long term, with a growing importance on providing them with technology that is constantly evolving to meet their needs.

Sheckler says ParaTrack equipment is designed to have a long service life and is fully rebuildable, with some of the original ParaTrack guidance equipment still operating to this day.

Local support

The company maintains close relationships with its distributors who maintain a staff of highly trained guidance engineers.

“Their experience with a wide variety of complex HDD installations makes them a valuable resource, not just while drilling the pilot bore, but for all stakeholders during the pre-job planning and bidding stages,” Sheckler says.

With the trenchless industry continuing to progress, Vector Magnetics has seen a shift from HDD as a niche installation method to its current position as the preferred option for the new installation of underground infrastructure. The company fosters a culture of innovation that thrives on solving the challenges HDD and trenchless guidance provide.

Sheckler says the introduction of the gyro survey tool to the industry is a recent example of this.

“As HDD has evolved from a method that was largely reserved for pipeline installations in relatively uninhabited areas to a favoured

installation method even in dense urban centres, there became a need for a guidance system that would allow drillers to confidently navigate those tight confines under heavy interference,” he says.

“In 2017 we commercially released the ParaTrack Gyro which greatly expands the scope of jobs that our customers can take on. The ParaTrack Gyro was developed entirely in-house specifically for the HDD market, and we are proud of what it brings to the industry.”

With technology at the forefront, the company continues to work closely with its distributors to ensure boots are on the ground using ParaTrack equipment to provide feedback to understand where the industry is heading.

Recently ParaTrack Guidance was provided through Prime Horizontal for a power installation project in Melbourne. Five bores of 180m length and 20m depth were drilled under a busy highway and parallel to a railway. The depth, lack of surface access, and interference levels made walkover guidance impractical. The ParaTrack Gyro was the preferred guidance system, as it enabled the bores to be drilled to profile from entry to exit in a location where there was no room for error. The installed 125mm cable bundles demonstrate the range of product sizes that ParaTrack technology is suited for.

Customer focused

Sheckler says service is where the company strives to really distinguish the ParaTrack brand.

“Selecting an HDD guidance system requires a great deal of trust from our customers, and we take that responsibility seriously,” he says. “ParaTrack equipment is designed to deliver long term value to our customers. For 43 years we’ve done nothing but guidance every day. We understand that an investment in ParaTrack is a commitment, and we’ll be there to support you when it matters.”

ParaTrack delivers cost-effective, highly accurate guidance that is effective for HDD projects of all sizes.

GRUNDODRILL 28N overcomes challenges during Queensland installation

Having the right equipment for a horizontal directional drilling (HDD) crossing is crucial in ensuring the crossing can be completed and is to specification. Making sure a rig and other equipment in the spread can comfortably achieve the length of the crossing, the radiuses required, the entry and exit angles, and so on is a basic requirement of every HDD job.

But when a project’s stakeholders truly want to leave as little as possible to chance and see the HDD method shine, as was the case on a recent HDD project in Rochedale, Queensland, an additional step should be taken: optimising the crossing for the equipment.

Flexibility for success

Last year, SEQ Trenchless was tasked with delivering contractor HDD under Bulimba Creek and the busy South East Busway to enable installation of a high-voltage, nine-conduit feeder bundle as part of the Brisbane Metro Project. With only a narrow construction corridor available adjacent to another busy road, sandstone ground conditions and plenty of services to avoid, the crossing had its complexities.

With project factors and initial recommended designs indicating the crossing would require a midi class rig, SEQ Trenchless knew this was the perfect job to showcase their brand new TRACTO Grundodrill 28N rig.

SEQ Trenchless director and HDD consultant Josh Taylor says the rig punched above its weight in the midi space.

“There was a lot that interested us in the 28N. Its features and capabilities have the potential to really push the limits of what can be achieved with a rig of this class, and we were keen to show this off at Rochedale,” he says.

“Compact enough to fit in the small available space, but promising some impressive power specs and features, we were keen to see what it could do.

As well as having the brand new rig on site, Taylor said the project benefited from a client who was experienced in the HDD method and open to ensuring risks were mitigated, and advantages maximised.

“Our client, Diona, was really supportive and motivated in ensuring the HDD was optimised

A successful HDD crossing requires good design, capable delivery, and the right tools for the job. When all parties understand this and are flexible in getting all factors right, success is assured.

for success, while keeping a conservative, riskaverse approach,” he says.

“This flexible attitude meant we had the freedom to apply some adjustments to the initial designs, tweaking to suit our equipment and methods. We did things like reducing the depth of cover slightly to be in range of walkover steering, but still providing adequate depth of cover to mitigate hydrofracture risk, and adjusting the entry angle to suit our vice heights – small changes, but a really worthwhile step in ensuring the crossing would go off without a hitch.”

Compact rig, big capacity

Drilling of the 308 m crossing commenced in November 2022, with SEQ Trenchless’ director and drill supervisor Shaun Newbigging on site overseeing the new rig’s capabilities.

“This was the perfect job for the new rig – 28 inch in rock conditions, with a horizontal curve and grade, all next to and under busy roads and a creek – plenty to contend with,” says Newbigging

“But we found it really performed, with a great balance between power and responsiveness. To ensure a good maiden voyage, we used a mud motor in a straight housing at the end of the drill string, with rock breaker sonde assembly in front.

“This was key for reducing steering lag in these variable strength ground conditions, as well as metro jobs where existing services are a factor. We also had to switch the rig

appreciation of the easy setup and demob arrangements for the rig, which was a plus.”

TRACTO Australia sales manager Daniel Toms agreed that the flexibility of the 28N opened up opportunities for contractors in the midi rig sector.

“The 28N brings the best of both worlds, with plenty of power, but remaining nimble and able to be compressed into a really small construction space,” he says.

“It punches above its weight in many

ways, with a 288 m rod magazine, 650 L/ min pumping capacity, and 28 t pull/thrust capacity and a maximum torque of more than 11,000 nM. This makes it perfect for small jobs, but it can comfortably stand on its own two feet when taking the next step up into longer and larger diameter crossings, even in hard rock.”

However, Toms said it was the smart features of the 28N which brought even more value for contractors.

“With a variety of automatic functions, like semi and full automatic drilling modes, automatic rod exchange and even automatic cleaning of the drill rods, these modern rigs are safer and easier to operate than ever with a small crew,” he says.

“Paired with unparalleled data logging and data transfer capabilities for today’s HDD designs, contractors have all the information and tools to not only be efficient and effective on this crossing, but to review and improve for the next one.”

One down, many more to go

The rig’s maiden crossing was delivered to great success, with pullback of the bundle completed without incident. Taylor said while good design and fit-for-purpose equipment were two important factors, the cooperation of all stakeholders was critical to the high level of success achieved on the Rochedale project.

“We really need to pay credit to the supportive, flexible approach by Diona, and their commitment to enabling us to adjust the crossing to minimise risk and complexity,” says Taylor.

“Paired with the support from TRACTO Australia in getting the most out of our new rig, we’re pleased with what we achieved and are looking forward to many more successful crossings with it.”

The triple bottom line benefits of trenchless technology

Gone are the days where project selection criteria was based solely on the benefits to corporate and business leaders. Nowadays, it’s no longer enough to focus on these benefits alone, and more contractors are on the hunt for equipment options that look at the bigger picture and offer triple bottom line benefits.

What is the triple bottom line?

The term triple bottom line (TBL) refers to the economic, environmental, and social benefits of a project (these three terms are also sometimes referred to as profit, people and planet).

TBL as a concept was first introduced in 1994 by John Elkington, the founder of a British consultancy called SustainAbility. He argued that all companies that report on their profit and loss should also be reporting on their bottom lines as they relate to how socially responsible their organisation is (people), and how environmentally responsible their organisation is (planet).

Since the term was first introduced in the 1990s, the broader concept of sustainability has exploded in popularity. A pivotal moment for the sustainability movement came on 1 January 2016, when the 17 Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development — adopted by world leaders in September 2015 at a historic UN Summit — officially came into force.

It is intended that over the next 15 years, the goals will mobilise efforts to end all forms of poverty, fight inequalities and tackle climate change, while ensuring that no one is left behind.

What does this have to do with trenchless technology?

In 2023, there is pretty widespread agreement that a focus on TBL reporting and sustainable operations are admirable and important goals for businesses to work towards.

And according to Jeff Lawson, General Manager of Sales at Vermeer Australia, when it comes to trenchless technology, the good news is that many of the different technologies that fall under the trenchless umbrella stack up well when it comes to sustainability and the triple bottom line.

Using the example of horizontal directional drilling (HDD), let’s take a closer look at how this technology can impact the triple bottom line of a project.

Environmental benefits of HDD

HDD offers a number of significant environmental advantages over the alternative

of open cut trenching. The act of trenching displaces a significant amount of soil –particularly when looking at a pipeline with a large diameter that needs to be buried at significant depth.

This disruption can also disperse dust into the surrounding environment, which can have a negative impact on air quality in confined urban areas.

Mr Lawson noted that by employing a HDD rig for pipeline installation instead, there is no displacement of existing soil, and no need to move displaced soil to another location (which in itself is an emissions intensive activity).

Social benefits of HDD

Lawson says for the community, utilising HDD for pipeline installation over open cut trenching also offers a number of benefits.

Open trenches for pipeline and cable installation can cause significant disruption to the local community, particularly in built up areas. It can lead to the closure of roads and footpaths while major works are being undertaken, which can inconvenience road and footpath users. Traditional trenching in areas where businesses operate can also have a negative impact on their ability to trade during a construction period.

“When installation by HDD is chosen instead, the site footprint of a project is

blocked off around the entry and exit points for the drilling rod,” Lawson says. “The installation path is generally untouched, with businesses able to operate as normal and traffic proceeding as usual.”

Economic benefits of HDD

Finally, it’s important to note that installation of pipe and cable via HDD can in fact be cheaper than traditional open cut installation methods –especially when the above factors are considered.

“While open cut trenching can be cheaper than utilising sophisticated HDD rigs, when you account for some of the hidden costs of traditional trenching, such as community disruptions, loss of business and potential environmental cost, HDD can in fact work out to be a more economical option for utilities, councils and tier 1 contractors to employ on their major projects,” says Lawson.

Thinking beyond the immediate

When undertaking large and complex infrastructure projects, the benefits of trenchless technologies such as HDD quickly add up.

In 2023, the triple bottom line and sustainability impacts of any works undertaken should always be undertaken by project proponents – and when doing so, trenchless technologies such as HDD come out on top.

People on the Move

the water industry for over a decade, has been appointed Country Manager for Australia and New Zealand at IMPREG. “My journey has brought me close to water authorities, engineers and major contractors in the Australian and New Zealand water industry,” he says. During this time, he became aware of the increasing demand in trenchless, particularly in the UV market with proven technology.

“The water industry can only continue to grow,” Murphy says.“Our populations are increasing therefore the demand on ageing water assets and the requirement for repairing infrastructure will continue to thrive.”

Murphy will be involved in all areas of the business with a strong focus on our clients, technical specification and overall growth of the technology.

He’s looking forward “to learning more about the UV technology,” and maintaining current relationships in the industry and developing new ones.

“Throughout his professional journey, Paul has prioritised staff, customer, and supplier engagement, fostering an atmosphere of openness and transparency.

Having Ormerod onboard is something the SECA team is looking forward to.

“It’s always exciting to bring fresh talent on board, and we can’t wait to see the great things they’ll accomplish.”

Aaron Long has started his new role as TRACTO’s Product Support Representative. With over 15 years in the trenchless industry as a diesel mechanic, product specialist, sales representative, and supervisor, Long’s role with the German-based company is to support TRACTO’s products, company and being part of continuous improvement. When reflecting on why he was drawn to this role, Long says it was the opportunity to be part of a small team with a good understanding of the industry with a wellbuilt product.

“I had a friend that worked in the industry, and he spoke highly of TRACTO, and I decided that it sounded like something very interesting and something I would really enjoy,” he says.

“It is a tight knit industry and a lot of help and support for people willing to give it a go.”

Long is looking forward to seeing how TRACTO’s products evolve and spending time with his new clients and helping them achieve their goals.
