President’s message

As we look ahead to the future, both globally and nationally, it is clear that the push for sustainability and greener practices is accelerating. With net-zero goals on the horizon, the trenchless industry stands at a unique intersection. By its very nature, trenchless technology offers a more environmentally friendly alternative to traditional methods. However, the need for innovation and further electrification of our equipment is evident as we work to keep pace with the global shift towards cleaner, more sustainable practices.

What is also becoming increasingly apparent is the role our industry will play in supporting other emerging sectors. These industries, which will undoubtedly rely on trenchless solutions, represent exciting growth opportunities. For example, Brisbane’s preparations for the 2032 Olympics and the ongoing energy transition to net-zero goals both present significant challenges — and trenchless technology will be essential in meeting them.

Take the Snowy 2.0 project as a prime example of how trenchless methods are being applied at scale.

As part of the pumped hydro project, the Snowy 2.0 team has already completed several horizontal directional drilling (HDD) shots and will continue to do so as they install a complex network of services around the mountains. This is a testament to the versatility and importance of trenchless techniques in large-scale infrastructure projects.

On the horizon for our industry, the ASTT is excited to announce No-Dig Down Under 2025, which will take place in Melbourne. This event promises to be a landmark occasion, filled with technical papers, networking opportunities, industry training, and an exhibition showcasing both established and cutting-edge products, services, and techniques. We look forward to seeing you there and to the continued growth of our community.

Looking even further ahead, the No-Dig International 2026 conference in Auckland is also on the agenda. This event will provide us with an excellent opportunity to engage with our international peers and further solidify the global presence of trenchless technology.

I am also pleased to report that the Young Trenchless Professionals Committee is thriving and already contributing valuable insights and ideas to the ASTT. Their enthusiasm and fresh perspectives are invigorating our industry, ensuring that we are preparing the next generation of professionals to lead us into the future.

Finally, the ASTT continues to expand its involvement in key industry bodies, including the Water Services Association of Australia. Our increasing participation in these organisations will benefit both our industry and our members, ensuring that trenchless technology is included in product standards and governing documents.

Rob Carr project claims national CCF award

Rob Carr and Water Corporation’s Quinns main sewer extension project was recently announced as a winner of the National Civil Contractors Federation’s (CCF) National Earth Awards in the $30 million – $75 million category.

It was announced in September that the project had claimed the CCF WA Earth award in the same category – now it has claimed the national accolade as well.

The project, delivered under a design and construct contract, involved 1.8km of slurry microtunnelling, open trench excavation,

and a challenging 500m curved drive beneath a freeway and railway.

Shaft excavations reached depths of up to 27m, incorporating two highly precise vortex structures. Much of the work was constructed within tight site footprints and environmentally sensitive areas.

Rob Carr General Manager Angelo Soumboulidis said receiving the award was a proud moment for the company, and another ‘fantastic result’.

“The Quinns main sewer extension project was a very intricate and complex project and

New water main to meet future needs of growing suburbs

Coliban Water is installing a new water main to increase the capacity, reliability and efficiency of its water network in the west of Bendigo.

The work between Golden Square, Maiden Gully and Marong will cater for population growth in the region for decades to come.

This pipeline development is divided into six sections, across two project phases, and will take a number of years to complete, with construction for Section A recently finished.

Construction will involve a mix of open trench and pipeline boring work. Local contractor S&R Engineering and Construction will be carrying out the works.

An upgraded sewer main, also going in between Maiden Gully and Marong, will provide the infrastructure necessary to meet the future needs of these growing suburbs, Coliban Water said.

Coliban Water recently announced that part of Section B will soon be underway from Olympic Parade to Rocky Rises Road.

The Marong Tank project was completed in December 2021.

Installation of the new three-megalitre concrete tank and booster pump station at Sterry Road meant consistent water pressure in the town, Coliban Water said.

Huge population growth in the west of Bendigo was the catalyst for the Marong tank project which delivered improved network reliability for the community of Marong.

More growth is expected in Bendigo’s western suburbs in the coming years with the new pipeline expected to help support this area into the future.

a fantastic achievement,” Soumboulidis said. “Ultimately it couldn’t have been achieved without a dedicated construction team led by Andrew Youngs, Paul Lee, Meadhbh Moloney, and Adam Shanley–and of course the support of a fantastic client in the Water Corporation. Well done!”

Rob Carr is part of global entities Soletanche Bachy, world leader in underground engineering, foundations and soil technologies and VINCI, world leader in concessions, energy and construction in more than 120 countries.

Trenchless tech keeps Swanston Street ticking

Vital upgrades to a water main on one of Melbourne’s busiest streets caused minimal disruptions due to the use of trenchless technology. Greater Western Water (GWW) completed upgrades on 250m of the almost 100-year-old water main along Swanston Street.

GWW worked closely with the Metro Tunnel Project, Cross Yarra Partnership and City of Melbourne to coordinate works with the construction of the new Town Hall Station, and manage impacts to pedestrians and local residents and businesses.

Due to the complex nature of Melbourne’s underground infrastructure, building new pipes requires careful planning to minimise disruption to other assets and services.

GWW’s delivery partner for this project, AquaMetro, used techniques to reduce the work’s impacts on nearby trees and allow for pedestrian access, including both slip-lining and pipe-bursting methods.

GWW general manager for growth and infrastructure Ian Burton said that delivering the upgrade now will reduce the need for works when Town Hall Station opens.

“Our pipes are built to last about 100 years and this water main, which was built in 1928, was in need of a vital upgrade to serve Melbourne’s growing population,” Burton said.

“We always do our best to minimise disruptions to the communities we work in and that’s why we’ve collaborated with other major projects in the area to coordinate works at the same time, limit the impacts and protect the city’s heritage.”

Completing the works alongside other construction in the area reduces the need to disturb heritage assets such as blue stone pavements and curbs again in the future, and reduces the amount of time this busy part of the CBD experiences disruptions due to construction activities.

Water works ﬂying and staying quiet

Queensland based utility Logan Water is working hard on its latest water main project, which is relying on trenchless technology to kept disruptions to a minimum. “We’re pleased to announce the start of the Travis Road Reservoir Trunk Water Main project – a 7.6km, 600mm diameter water main that will connect the Southern

Regional Water Pipeline to the Travis Road reservoir in Logan Village,” Logan Water said. The project commenced late last year, and began with detailed design, incorporating innovative methods including horizontal directional drilling (HDD) to tunnel under Camp Cable Road and the Logan River, minimising public disruption

during construction. The team successfully used HDD to complete 422.8m-long space needed for the new pipeline beneath the Logan River. HDD was also chosen at Kenny Road.

The 531.5m of drilling is complete, and final preparations for pulling the pipe are on track for the coming weeks.

Greater Western Water completes upgrades in Moonee Ponds

Greater Western Water (GWW) has completed a significant upgrade to replace a more than 140-year-old water main on Pascoe Vale Road.

The new main has increased capacity to provide safe and reliable drinking water to residents in Moonee Ponds, meeting the city’s growing population and water needs for the next century.

The works involved replacing 3km of water pipes in Alexandra Avenue, Feehan Avenue, McPherson Street, Albion Street and Pascoe Vale Road.

GWW’s general manager of growth and infrastructure Ian Burton said the project has increased reliability and protection against water loss and leaks for the community. “This has been a long-running major project

to future proof our water infrastructure,” Burton said.

“We know it has caused some inconvenience to those who live, work and travel in the area, and we thank the community for their patience and understanding while we’ve delivered these essential works.

“With this upgrade, our Moonee Ponds customers can count on a more reliable water supply and fewer interruptions for years to come, ensuring they have water when they need it.”

GWW partnered with Jaydo Construction for the project and worked closely with local residents, businesses and other stakeholders throughout the project to manage impacts and keep people updated on the works. Jaydo used horizontal directional drilling techniques, which enabled the team to reduce the traffic and public transport impact of the works, compared with using more traditional trenching methods.

All construction sites have been restored to their original condition and all impacted roads have fully re-opened.

“By partnering with like-minded industry leaders, we are strengthening our market position without losing sight of the principles that have built our reputation.

“As we consolidate in this space, our focus remains on delivering innovative, e cient solutions while staying true to the foundations of our business.”

e additional water main will support population growth in this region by expanding the capacity of a local reservoir, improving system reliability, and maintaining the supply of water to residents.

e population in Sydney’s north west

Rob Carr is capable of complex projects while maintaining a hands-on, solutions-driven approach.

is expected to double by 2056. e North West Wastewater Connection Project is part of a suite of projects that will upgrade infrastructure and enhance the resilience of wastewater treatment in the region.

“ is work is part of a transformative investment to ensure water, wastewater and stormwater systems meet the need of Sydney Water’s customers now and into the future. We are proud to play our part in delivering this vital infrastructure that will support Sydney’s growing population and ensure the overall liveability of our city,” CEO Bouygues Construction Australia Seved Robin said.

e North West Wastewater Connection project will involve the construction of a new underground pipeline circa 1km long connecting the pumping station in Rouse Hill to the Rouse Hill Water Resource Recovery Facility.

e work also incorporates 802m of microtunnelling over two drives. ere will also be upgrades at the pumping station to increase capacity and provision for emergency power supply.

In addition to the improvements to Sydney’s water infrastructure, the Ironbark JV has committed to implementing a range of sustainability initiatives and strategies on the project that will help deliver positive environmental, social and economic outcomes for the broader community.

Building on the success of the Ironbark

JV, another key strength of Rob Carr lies in its versatile team of highly skilled professionals, whose collective knowledge spans technical, operational, and project management expertise.

NSW soars ahead with trenchless tech

From big contracts to international recognition, New South Wales set the standard for trenchless practices in 2024.

The nal quarter of the year was particularly big for New South Wales, as a number of awards and contracts were given out across the state.

Trenchless project in NSW receives international recognition Michels Corporation has been recognised as the runner-up for the IPLOCA Excellence in Project Execution Award for its work on the Snowy 2.0 horizontal directional drill (HDD) in New South Wales.

e project included a 2248m drill with a 563m vertical elevation change, and saw the drill and pipe installation completed by Michels Trenchless, a branch of Michels Corporation.

Completing the project safely while maintaining strict environmental standards required Michels to innovate all phases of planning and construction.

Rather than perform a conventional one-rig pilot hole, Michels determined the pilot hole intersect method would be a better way to achieve the customer’s project goals.

e pilot hole intersect method deploys two drill rigs, one drilling from the entry side and one from the exit side, to meet at a predetermined location along the alignment.

e team used two Michels-designed and fabricated rigs, each with 880,000 pounds of push/pull force.

e pilot hole intersect method allowed the team to manage uid pressure in the drilling column and from returns; contend with a high water table, minimise push forces; and facilitate steerability through hard and fractured rock.

e HDD project supports Snowy 2.0, the largest renewable energy project under construction in Australia.

Innovative solutions for stormwater harvesting

Empire Infrastructure is supplying innovative solutions to support the Bathurst Stormwater Harvesting Project.

Announced in December 2024, the project is part of a $20 million investment from the NSW Government to boost Bathurst’s water security by providing another reliable drinking water supply.

e stormwater harvesting scheme includes a 36 megalitre storage pond o Morrisett Street and an eight megalitre storage pond at the Water Treatment Plant to capture stormwater run-o from drains and local catchments.

Once it is harvested and collected, the stormwater will be pumped back to the Bathurst water treatment plant for ltration so that it is safe to use.

e scheme will have the ability to capture around 1500 megalitres of stormwater during rainfall and runo events every year – which is approximately one third of the water used by Bathurst when under water restrictions.

Empire Infrastructure is supplying 4.6 km of the GRP pipes produced by Future Pipe Industries for the Bathurst Stormwater Harvesting project.

“ ese high-performance pipes are crucial in capturing and reusing stormwater, ensuring strong water management for the growing Bathurst community,” the company said.

“ is project highlights our commitment to driving innovation and sustainability through smart infrastructure that meets today’s challenges and tomorrow’s needs.”

e NSW Government has invested $20 million to deliver major water security projects in Bathurst.

Tunnel boring machine hits major milestone on Snowy 2.0 project

e Snowy 2.0 pumped-hydro megaproject marked a signi cant milestone, with one of three tunnel boring machines (TBM), Lady Eileen Hudson, now two-thirds of the way through its second tunnel excavation.

e TBM is approximately four kilometres into the six kilometre ‘tailrace’ tunnel, which will link the lower Talbingo Reservoir with the massive 20-storey underground power station.

TBM Lady Eileen Hudson previously completed a 2.85km main access tunnel, which is now being used by construction teams to reach the underground power station site.

Drill and blast works are also advancing at the Talbingo water intake, creating a new 700m tunnel between the intake structure and the tailrace tunnel.

e Talbingo intake is located in very steep terrain and following excavation of 570,000m3 of material over two years, the rock face is now 110m high.

NordiTube acquires Aussie Trenchless NordiTube Group’s Australian subsidiary has grown its presence in the Australasian region with the acquisition of Aussie Trenchless.

e acquisition allows NordiTube to provide a spiral wound, whole of service for pipes DN 150-2400, including the Nordiloc S and Nordiloc X systems.

NordiTube equipment will be built, serviced and supported by KRE Engineering in Sydney, New South Wales.

Aussie Trenchless Director Chris Meredith, a pioneer of the no-dig sector, is entering retirement after 40 years of service.

Precision matters

Channeline’s fully-structural GRP lining systems are custom designed and manufactured to ensure a precise fit within any existing structure, ensuring optimal efficacy for generations to come.

Ticking all the boxes

Channeline is delivering sustainable pipeline rehabilitation with its versatile and bespoke lining solution.

Pipeline projects are becoming increasingly complicated in modern urban environments thanks to population density, rising operational costs, and the push for sustainable business practices. Fortunately, Channeline has a pipeline lining solution to tackle all three of these issues.

Channeline has distinguished itself in the pipeline sector with its bespoke structural glass reinforced plastic (GRP) lining systems since the 1980s.

e technology has come a long way since in that time and today is available as a unique multi-segmental solution that allows the liners to be assembled on-site.

It can also be manufactured in tailored shapes and sizes to suit even the most niche of pipelines. is fully structural lining solution is suitable for the rehabilitation of sewers, tunnels, culverts, stormwater and other buried structures. But in a busy urban environment, access points to these assets are often small, with the cost of excavation and refacing streets in turn incredibly high. Enter Channeline’s lining solution.

“ is technology allows installers to transport our liners through access points that are smaller

than the diameter of the actual sewer that is being repaired,” Channeline Quality Assurance and Quality Control Manager Dr Dev Chelot said.

“ is means that no additional excavation is required. e segments can simply be brought

into a small access point and assembled and installed inside the sewer or tunnel.”

With a design life of 150 years, Channeline’s multi-segmental lining does not yield any ground when it comes to strength. In fact, Chelot said the product is much sti er than traditional single piece pipes.

“We designed the lining system in a certain way so that the load-carrying capacity of the joints increased,” he said.

“It takes more load to de ect a multisegmental pipe than to de ect single piece pipe.”

Beyond longevity, Channeline can also help businesses drive down operational costs and carbon emissions.

“We’re reducing the fuel cost for transporting the pipes, because if ve trucks are needed to transport single piece pipes, Channeline may only require one or two trucks to transport our multi-segmental pipes of the same geometry,” Chelot said.

“Additionally, minimal excavation work is required to install the Channeline product.

“So in these ways, we’re saving carbon emissions by reducing fuel consumption and driving down overall costs.”

Images: Channeline

Channeline employs a variety of in-house and on-site training and supervision for all of its staﬀ and customers.

Channeline lining is highly customisable.

Putting the pieces together

Channelbond is a meticulously engineered structural adhesive that brings the entire multi-segmental package together.

Designed and produced by Channeline to assemble its multi-segmental lining, the adhesive is resistant to 14 di erent chemicals and is suitable for use in acidic environments.

According to Chelot, Channelbond was designed to give contractors greater control over the installation process.

“We set out to make an adhesive that is both mechanically strong and simple to apply,” he said. “Most of the adhesives in the market are all temperature controlled, which means that the curing time is massively dependent upon temperature.

“But our product allows contractors to adjust the mixing ratio, which can make curing time longer or shorter as required.

“For example, if a contractor wants to cure a section in 20 minutes, all they have to do is adjust the mixing ratio as per what we recommend.”

Channeline’s multi-segmental technology, working in unison with Channelbond, is giving contractors and asset owners greater control over their pipeline projects, while also driving down costs and carbon emissions.

The world’s most compact hot

tapping machine

Minitap’s patented technology provides a portable, robust and safe hot tapping solution for large offtake hot tapping in confined space environments

• Advanced cutter designs

• Comprehensive training program

• Local service & support

• Designed and manufactured in Australia

Multi-segmental design means lining can be transported through much smaller access points.

Built by contractors for contractors

Minitap is making hot tapping more eﬃcient and cost-eﬀective than ever.

In a market where services contracts are often set on a xed price basis, pipeline contractors cannot a ord delays and disruptions. is places the onus on the contractor to drive e ciency in their work, while also maintaining a high degree of safety and overall cost-e ectiveness.

But there are a multitude of factors that the pipeline contractor market has to contend with; access points can be small and the ground often dense with numerous other utility pipelines, and many other factors which threaten to complicate things.

“ is calls for a surgical approach to services delivery,” Minitap Managing Director Ben Worst told Trenchless Australasia

“ e contractor wins by having an e cient and repeatable process which delivers a predictable result as it lowers the frequency of unplanned overruns.”

With such crowded and con ned workspaces, it can be particularly challenging to conduct pipeline maintenance work such as live tapping, which typically requires large machinery.

“Today, utility services contractors are operating in a very crowded in-verge work area, which often does not allow access for traditional large frame equipment for large o take tappings,” Worst said.

“ is usually calls for time-consuming re-

routing of connecting pipework, or delays and service interruptions to shut down pressurised pipes to cut in new connections. All of this contributes to added time, cost and utility service level degradation.”

Fortunately, having the right tool on hand can make all the di erence. And that’s where Minitap comes in.

Minitap allows for large o take hot tapping (up to 200mm) in standard low pressure (up to 1000 kilopascals) pipes. It was designed speci cally for the water utility industry but can also handle other utility service pipes such as gas and chemicals.

While conventional hot tapping machines are equipped with an elongated drive shaft that makes it di cult to t these machines into con ned spaces, Minitap is designed to t and operate in just a 1m¬2 area.

“Since inception, the hot tapping equipment sector has seen little change, but the needs of the market are evolving,” Worst said.

“Minitap broke the mould by taking a contractor view and challenging current design parameters.

“By having a man-portable tool which can t into a 1m¬2 workspace, Minitap allows the contractor to tap a higher volume of services, driving up e ciency and pro tability.”

Minitap is hydraulically driven, making the machine safe for use in waterlogged or

ammable environments. is both supports the compact design and further enhances user safety.

Cleanﬂow Environmental Solutions’ 100-year approach to WA pipelines

Overcoming challenges with advanced trenchless technology, sustainable solutions, and reliable partnerships.

Clean ow Environmental Solutions is leading the way in pipeline renewal across Western Australia, delivering long-term trenchless solutions that reduce operational costs and extend the life of critical infrastructure. With a strong commitment to sustainability and community responsibility, the company continues to set new standards for environmentally friendly rehabilitation projects.

To achieve these high standards, Clean ow Environmental Solutions uses SAERTEX multiCom® portfolio of UV-cured glass-reinforced pipe liners for its projects. e liners for gravity application have a technical service life of 100 years, providing reliable, long-term solutions that signi cantly reduce maintenance costs.

“SAERTEX-LINER service life gives us the con dence to assure our clients that we are delivering durable solutions, minimising maintenance costs, and reducing the overall life cycle costs of the new asset”, Sandro Milieri, CEO at Clean ow Environmental Solutions said.

SAERTEX multiCom, a global leader in trenchless technology, manufactures its liners under stringent ISO 9001 and ISO 14001 standards. ese certi cations ensure quality across every stage, from manufacturing to impregnation, storage, and delivery.

With local stock and custom orders available in Australia and New Zealand through Pipe Core, Clean ow Environmental Solutions relies on these liners for both urgent and planned projects.

“SAERTEX multiCom o ers a variety of liner types for both gravity and pressure applications to meet the needs of various renewal scenarios,” Katharina Helming, SAERTEX multiCom Business Development Manager said.

“Further still, SAERTEX multiCom has undertaken the necessary testing to verify the expected 100-year technical service life.”

For a challenging project commissioned by the Water Corporation in the City of Melville, Western Australia, Clean ow Environmental Solutions selected the SAERTEX-LINER® MULTI Type S+.

Renowned for its thinner wall thickness and structural integrity, this liner was ideal for rehabilitating over 500m of severely deteriorated sewer pipeline.

“Our liner range is suitable for both partially and fully deteriorated pipes, making it an ideal solution for such challenging conditions,” Helming said.

CCTV inspection revealed the pipeline’s condition was worse than initially anticipated, with defective joints and holes in the pipe walls allowing in ltration into the sewer system. e unknown thickness of the pipe wall posed a signi cant risk of failure.

e most demanding section, 189m of DN990 pipeline, presented substantial logistical and technical challenges, including collapsed sections of pipe.

“Previous attempts from other agencies to clear the pipeline had failed, adding complexity to the rehabilitation,” Milieri said.

Clean ow Environmental Solutions addressed these challenges with its robotic cutter and specially designed carriage. e crew successfully removed large sheets of delaminated internal plastic liner from hard-to-reach areas. is innovative setup enabled precise cutting without compromising the pipe’s structural integrity - a task unattainable with conventional equipment. is innovation was pivotal to the project’s success.

Over a three-week period, a seven-member crew renewed the network. e result was a seamless, joint-free pipes with a 100year technical service life, enhancing ow e ciency and avoiding the disruption of open trenching.

“With its superior mechanical properties, SAERTEX-LINER can be produced in very low wall thicknesses, ensuring only minimal

Mullane and its supply partner IMPREG are delivering timely and high-quality relining projects across NSW.

Based in NSW’s Central Coast, Mullane Trenchless Pipeline Solutions is an expert in all things trenchless works, with a particular emphasis on pipe relining and repairs.

“We specialise in pipe relining along with the ancillary services that go with it, such as CCTV inspection, pipe cleaning, and asset mapping,” Mullane Trenchless General Manager Civil Infrastructure Director Luke Woodward told Trenchless Australasia

“We also sit within an established parent company, H L Mullane, which specialises in civil pipeline construction. is means when clients come to us with projects that are part trenchless and part civil, we’re able to selfdeliver the whole thing.”

is broad scope of capabilities sees Mullane Trenchless regularly engaged in civil and pipeline projects for councils, water authorities, and heavy industries such as mining.

With such high calibre projects, the fullservice pipe rehabilitation company is just as careful with its work as it is with its choice of supply partner.

Enter IMPREG.

As one of the world’s leading manufacturers of cured-in-place-pipe (CIPP) liner systems for UV-curing, IMPREG is a supply partner of choice for Mullane. e company’s agship GL16 liner was developed for all common pipes from DN150 to 2000 for sustainable and e cient trenchless rehabilitation.

Boasting over 100 years of design life, high quality UV resins, easy installation, and extreme durability even under tough conditions, it’s not hard to see why IMPREG is an important part of Mullane’s arsenal. e supplier was called on once again when Mullane Trenchless Pipeline Solutions was awarded a large package to deliver relining works for various ood pipes. is included some pipes that were impacted by tidal ows.

“We opted to procure the full package worth of GL16 UV liners ranging from DN375 to DN1500 from IMPREG,” Woodward said.

“Tidal ows, remoteness, and di cult access made the projects signi cantly complex, but we drew from our combined trenchless and civil

skills to deliver the package in a timely and environmentally friendly way.

“We found that by ordering the full materials package through IMPREG and having it delivered to their Newcastle facility – only an hour away from us – we were able to easily arrange pick up and delivery of the liners each day to the sites. is minimised delivery times, making the project much easier and allowed us to focus on some of the more complex challenges.”

anks to the combined prowess of Mullane Trenchless, IMPREG and H L Mullane, the stormwater pipes were relined to a very high standard and are ready for action for decades to come.

Tequa invests in its most important asset – its people

Tequa Plumbing & Civil is already a well-renowned business within its local region, and this new initiative to wrap its equipment, raising awareness for mental health and showcasing value for employee welfare, only boosts its positive reputation, value and reach.

Tequa decided to wrap one of its Vermeer vacuum excavators in TIACS branding.

Asecond-generation family business that began in 1975 in regional Victoria, what started out as a plumbing-based business naturally migrated into a heavy civil stream, particularly over the last 10-15 years.

Daniel Smolenaars is one of the business’ longest standing team members, starting out as an apprentice in 1990 and now, 35 years on, Tequa Plumbing & Civil’s Managing Director. He’s seen the business throughout its expansions into new markets over decades.

“With plumbing you naturally have a civil background with the underground assets you install, including water, sewer, gas and stormwater, so overlaying that into the civil/ utilities market was a natural t for us as we expanded the company,” Smolenaars said.

Nowadays, Tequa is primarily focused on earthmoving, pipe laying, drainage, directional drilling and vacuum excavation services over and above the plumbing services they’ve provided the Gippsland community for 50 years.

“Being based in regional Victoria, it’s probably the diversi cation of our services that underpinned a secure employment in regional areas.”

‘Putting your money where your mouth is’

e Tequa team pride themselves on the large focus they devote to sta engagement and run several programs to help support the breadth of their people, including leadership programs, teambuilding programs, and mental health and awareness programs.

“We value our team; they’re like family to us,” Smolenaars said.

Tequa recently partnered with TIACS ( is is a Conversation Starter), a free counselling initiative providing mental health advice from quali ed professionals to the bluecollar community. TIACS was created by the founders of social impact workwear company TradeMutt, known around Australia for their loud, vibrant work shirts which were designed to start conversations about mental health, making an invisible issue impossible to ignore.

e Tequa team had an idea to go bigger than the uniform change and with that, decided to wrap one of its Vermeer vacuum excavators in TIACS branding – making the

equipment and team stand out loud and proud wherever they are, and becoming its own conversation starter.

“We do the once-a-year celebratory events like R U OK? Day and Movember, but this equipment wrap is us saying we’re here all year round, fulltime, for our people,” Smolenaars said.

“It’s not just a poster on the wall – we’ve gone the full length.

“Every time that truck is driving around it’s a conversation starter. It’s generating curiosity amongst our team and our clients, so it goes beyond ‘feel good’ and ticking the box to actually putting your money where your mouth is.”

Looking for the same ‘family’ attributes in the supply chain

Tequa’s value for the people it employs extends to the people it chooses to partner with in the supply chain, including its equipment dealer.

“We’re all about relationships – so whatever we can do to protect the relationship and longevity of our people; we look for the same attributes in people we deal with in the supply chain,” Smolenaars said.

Tequa’s relationship with its local Vermeer Australia team dates back to 2008 when it bought its rst machine. Adding more and more Vermeer equipment to its eet over the last 16 years, Tequa’s now has four horizontal directional drills and six vacuum excavators.

e company claims the success of its ongoing relationship with Vermeer Australia comes down to the support received by the sales and service teams.

“Our local area manager, Adrian Greed, has been very good at getting us the right equipment at the right time. And he’s always available for after-purchase questions or queries,” Smolenaars said.

“ e boots on the ground guys who manage and service our eet are amazing – they go over and above.

“We owe it to Matt Frearson and Bryce Lewis – those two guys alone keep us coming back to Vermeer because of their in eld expertise.”

NDD when and where it’s needed

Vacuum Truck Supplies’ DrainVac and DiggerVac are delivering reliable non-destructive digging and drain cleaning to projects across Australia.

An increasing demand for utilities across Australia means that the space below ground is quickly becoming a spider’s web of pipes and cables. Accessing these networks is a complicated task, with access points often con ned, and the everpresent risk of damaging a cable both costly and dangerous.

at’s why contractors are turning to non-destructive digging (NDD), a safe means of excavation using high-pressure water and vacuum technology, usually delivered via a vacuum truck.

But not all vacuum trucks are created equal. With over 30 years of experience and over 1000 vacuum trucks built to date, Vacuum Truck Supplies (VTS) is backing the trenchless industry with high-quality, safe and compliant equipment.

e latest vacuum trucks to hit the company’s shop oor are the DiggerVac and DrainVac, with the latter boasting additional drain cleaning capabilities.

Both vehicles are available in a mobile 6x4 con guration, with larger 8x4 models bound for market in the coming weeks.

To deliver these powerful machines, VTS partnered with manufacturer Aryan Pumps and Enviro Solutions, which has been building NDD solutions for more than a decade and has delivered hundreds of trucks all over the world.

“With Aryan’s proven history of manufacturing highest quality, robust and tough trucks, and VTS’ design expertise based on our experience in Australia, we’re very con dent in the reliability of the product,” VTS Managing Director Rod Glue told Trenchless Australasia

“Just like all our trucks and trailers, they’ve been designed to withstand the harshest Australian conditions and are built be abused.”

Both the DrainVac and DiggerVac models have stainless steel waste and water tanks, tipping tanks, and full opening rear doors, and a non-computer control system.

is nal feature is key, Glue said, and means the vehicles rely on mechanical and hydraulic engineering standards that have been proven for decades.

is translates to simplicity in diagnostics, repair and maintenance, all of which is of critical importance in every project. It also helps to lower the total cost of ownership throughout the asset’s life.

“Vacuum Truck Supplies has designed its own simple non-computer-controlled system which is tted to all VTS models

including these two new units,” Glue said. “ e Australian NDD market has long had a plethora of European imported vacuum trucks which are hugely complex with computer and software issues dogging even the simplest of tasks.

“ is often results in unnecessary lengthy and costly downtimes while they are xed. Customers won’t have these issues with our trucks.”

Designed with the market expertise of VTS and delivered by the trained hand of Aryan, the DiggerVac and DrainVac are built on proven foundations.

Together, both companies are delivering mobile NDD and drain cleaning across Australia when it’s needed, where it’s needed.

Pipe ramming paves the way under NZ highway

When CT Civil recently took on the challenge of installing 53m of steel carrier pipe beneath the State Highway in New Zealand, it relied on TRACTO’s GRUNDORAM TAURUS pipe ramming system to get the job done.

Established in 2008 as Concrete Treatments NZ Limited, CT Civil initially specialised in drainage rehabilitation for the municipal sector.

Over the past ve years, the company has shifted to focus on broader civil construction, re ecting the growing demand for its expertise in tunnelling, trenchless pipe installation, bentonite and slurry mixing and support, as well as dewatering and desludging.

In 2022, the company rebranded to CT Civil, highlighting its expanded focus on civil construction and engineering.

With over 20 years of tunnelling experience, Bishop and the CT Civil team have delivered challenging projects in unique environments, maintaining a commitment to safety, quality, and client collaboration.

e 53m section, constructed using trenchless pipe ramming, was part of a larger project to install a new sewer underneath one of the North Island of New Zealand’s major arterial roads, SH.

CT Civil was contracted to complete construction of the trenchless section of the project by principal contractor Brian Perry Civil.

A trenchless method which is becoming more common in New Zealand and Australia, CT Civil Director of Operations Leigh Bishop said the ground conditions played a crucial role in the decision to use pipe ramming.

“ e ground was very unpredictable,” Bishop said.

“We encountered large cobbles, timber, rail sleepers, concrete, and general ll materia.

“Pipe ramming was the best solution for ensuring we could navigate those obstacles and reach the other side of the highway.”

e area presented additional challenges, with an old creek running through a gully that had been lled in over time.

“We needed access to the face of the pipe to deal with obstructions as we encountered them on the drive, and pipe ramming allowed us to do that e ciently.”

Using TRACTO’s GRUNDORAM technology, CT Civil achieved an impressive result, with the alignment of the pipe exiting within 30mm of the target, which was crucial to the success of the installation.

“ e accuracy was remarkable given the ground conditions, and we made some small

adjustments to the cutting shoe,” Bishop said.

e GRUNDORAM system is renowned for its accuracy, along with a list of other features, including strength, versatility and power.

e dynamic steel pipe installation method applied by the machine enables the economic installation of casing or product pipes up to 4m diameter in soil classes 1−5.

is includes installations underneath roads,

railway tracks and rivers over lengths of up to 100m.

As the machine progresses through the ground it can navigate through the toughest of geologies and conditions.

CT Civil identi ed multiple challenges present at the job site during the design and planning phase of the project, including foreign objects and a high water table.

Pipe ramming can help to navigate obstacles in tough conditions.

e contactor removed spoil by hand throughout large sections of the installation from within the casing.

“ is reduced friction inside the pipe and allowed us to deal with obstructions more e ectively,” Bishop explained.

“If the pipe stopped moving, we could excavate to the face and use di erent methods to remove or work around the blockage.”

Bishop said pipe ramming o ers a number of bene ts over other forms of trenchless construction, especially when it is backed up with the support of TRACTO’s local and international team of experts.

“ e 1.65m diameter carrier pipe, with a wall thickness of 25mm, required 40 hours of welding per joint, which was a signi cant undertaking,” said Bishop.

“But with the support of the team at TRACTO Australia we were able to navigate these challenges and deliver a successful outcome for the principal contractor and asset owner.”

TRACTO is one of the world’s leading trenchless technology companies, providing smart no-dig solutions for underground infrastructure projects worldwide, including energy, water and communications installations.

TRACO sales manager Dan Toms said the company has seen an increase in the popularity of pipe ramming in Australasia.

“Pipe ramming is one of the most versatile forms of trenchless construction,” he said.

The TAURUS is part of TRACTO’s extended range of pneumatic pipe ramming tools.

“It can also be used for what we call ‘HDD assist’, meaning the GRUNDORAM systems can be used to install a conductor barrel casing, providing a favorable starting point and friction free pullback section for directional drilling in di cult soil conditions.”

Driving innovation in complex infrastructure

Tunnelling Solutions has rapidly evolved from its humble beginnings in 2014 to become a key player in the tunnelling and underground construction industry.

Known for its technical expertise and ability to handle high-risk, complex infrastructure projects, Tunnelling Solutions has garnered a strong reputation for delivering results in the most challenging environments.

Founded as a consultancy in 2014, Tunnelling Solutions began with a small but highly skilled team focused on providing expert tunnelling services.

In 2022, Tunnelling Solutions became a wholly owned subsidiary of Gamuda Engineering. is partnership has proven crucial in bolstering Tunnelling Solutions’ ability to undertake large-scale, technically challenging projects.

Looking back at the early days, the company’s rst successful project in 2015 set the stage for rapid expansion.

Co-founder Harry Lyle mobilised a team to take on Project Arncli e, a 30m long tunnelled underpass, overcoming several key challenges with poor ground conditions including live rail only a few metres above the tunnel.

e company’s expertise spans several tunnelling disciplines, such as shaft excavation, pipe jacking, auger boring, road header and drill and blast excavation, and the management of tunnelling operations across various projects which range in size and scale. To build on this strength, in 2024, Serhat Baycan was appointed the new CEO of Tunnelling Solutions.

With a background in geotech and piling, Baycan has more than 30 years of experience in the construction industry having worked on iconic projects around the world. He knows too well the importance of delivering major projects and adapting the business to market needs.

Over the last few years, as the company continues to grow, Tunnelling Solutions has diversi ed its expertise to include utilities and water infrastructure projects. is pivot is in response to market trends, as demand for water and sewer systems continues to rise with growing urban populations.

Further strengthening the company’s expansion into the water sector is the recent acquisition of a microtunnelling boring machine (MTBM) from Herrenknecht. is machine is speci cally designed for smaller, specialised tunnelling projects, such as those needed for urban sewer and water systems.

e compact design of the MTBM allows it to operate in tight urban spaces, where space constraints are often a major challenge. With this investment, Tunnelling Solutions is well-positioned to lead into the utilities sector, o ering tailored solutions for sewer and water tunnelling projects that require precision and advanced technical capabilities. Tunnelling Solutions’ success is built on a well-de ned approach to project delivery. Each project follows a clear methodology that prioritises safety, e ciency, and quality at every stage.

“Tunnelling Solutions’ methodology is focusing on innovation and nding ways to do things smarter, including changing designs to better suit the project,” Project Superintendent Matt Lyle said.

“Gamuda has a similar value bringing innovation and technology to improve tunnelling industry capability.”

One of these innovations includes bringing technology developed by Gamuda for automated tunnel boring machines (TBMs) to Australia for use on a major tunnelling project in Sydney.

e sophisticated arti cial intelligence software, previously used in Kuala Lumpur, is installed inside the TBM and has the capability to automatically steer, operate, and monitor the machine, while an operator remains in control.

Delivering major infrastructure projects

Tunnelling Solutions has been involved in many major projects, including the Level Crossing Removal Works on Glenroy Road in Melbourne. e company completed a 1.2m diameter, 360mm pipe jack on a lump sum contract, using an AVN1200 slurry machine provided by the client.

e project faced challenges, including soft clay and low cover (600m) near a live rail, which could have led to delays and increased costs. Tunnelling Solutions responded by making improvements to the slurry treatment plant at 100m into the drive, improving productivity and reducing slurry costs.

Its innovative approach ensured the project was completed on schedule and within budget. In addition to the company’s microtunnelling work, Tunnelling Solutions has also completed drill and blast tunnels in Co s Harbour and Lake King William in Tasmania.

Growth and future outlook

Tunnelling Solutions’ growth trajectory has been impressive. From a privately owned company led by its industry heavyweight founders Harry Lyle and Craig Farr to a company comprised of more than 250 employees delivering complex projects for Tier 1 contractors on major projects across infrastructure and water.

Tunnelling Solutions, thanks to the backing of a Tier 1 company like Gamuda, has carved out a niche for itself by combining advanced technical know-how with on-the-ground management capabilities, delivering quality outcomes even in high-risk, technically

Strengthening ground integrity with microtunnelling

Consistently pushing the boundaries of trenchless innovation, Edge Underground recently completed a complex microtunnelling project in Sydney that required lateral thinking and customised solutions.

This time, rather than installing sewer or water pipes, Edge Underground installed a canopy tube style structure in order to facilitate the excavation for the future GreenWay tunnel under a rail bridge.

A project that has been in the works for some time, the proposed GreenWay will be an environmental and active travel corridor, linking two of Sydney’s most important waterways. Following the route of the Inner West Light Rail, the GreenWay integrates bike paths, historical sites, public art, community spaces, and natural bushland.

A recent stage of the project required a tunnel to be built under Longport Street – a task that required expertise, adaptability, and innovation.

Complex site constraints and precision requirements

Edge Underground’s role in the project involved supplying and installing 19 canopy tubes – each 21m long, 508mm OD, 9.5mm thick, mild steel casings – to reinforce the ground and ensure structural integrity for the upcoming commuter tunnel. ese canopy

tubes were installed and then lled with grout, each forming a solid bar through the ground. Unlike conventional pipeline installations, no infrastructure passes through these pipes; instead, they serve as reinforcement for the tunnel before it is excavated.

is method was chosen to create a structurally stable tunnel beneath Longport Street to allow the bike path to pass through.

e existing, longstanding brick built-up embankment and bridge (road over rail) required careful handling to prevent any movement during construction.

With the canopy tube arch successfully completed, the larger tunnel works can commence.

Images: Edge Underground

Ensuring the integrity of this structure, coupled with a very busy road overhead, added an extra layer of complexity to the project. e authorities have very strict monitoring conditions set for the project as there as several unknowns within the bridge, and settlement was not an option. Additionally, Edge Underground faced several key challenges:

• Limited access: Work e ectively had to be completed from one end of the project site, with limited access for a reception shaft.

• Diverse ground conditions: Drilling through a brick masonry embankment and other unknown ll materials, combined with parts of soft ground, voids and old rail back ll. Large man-made dry wall structures were encountered within the embankment, which also caused issue with the grouting process.

• Platform limitations: An adjustable platform was required to manage the installation process e ciently.

• No disruption to road infrastructure above or rail infrastructure running alongside the project: Minimising ground movement and maintaining stability throughout construction.

Pioneering microtunnelling approach

As the specialist microtunnelling contractor, Edge Underground deployed an enhanced AXIS machine upgraded with AdaptX technology to execute the works with precision. e project followed a four-step sequence:

1. Core drilling through the masonry wall at both ends of each canopy tube.

2. Microtunnelling the 508mm OD steel casings to exact line and level, forming a structurally sound arch.

3. Installation and grouting of canopy tubes to secure their positions.

4. Removal of the microtunnelling platform and conventional excavation of the internal arch to complete the cycleway.

Achieving the project’s goal required both lateral thinking and innovative solutions. Stuart Harrison, Founder of Edge Underground and CEO of OptionX Group, shared some of the key challenges encountered on-site.

“Drilling through up to 1.2m of brick revealed a mix of foreign objects embedded within the masonry – e ectively unpredictable ll material – which has the potential to make the process incredibly challenging. On top of that, the surrounding soil conditions were highly variable, shifting from compacted material to lose, soft zones,” he said.

“To maintain accuracy under these conditions, we needed the ability to retract and make real-time adjustments to our casing advancement system and drilling parameters. is ensured we stayed on-line and level while minimising excessive wear on the tooling.” is custom-engineered casing advancement system was developed in-house by OptionX Group and manufactured at OptionX Bournedrill, reinforcing Edge Underground’s ability to design, re ne, and execute custom solutions for challenging projects.

“For a job like this, minimising the number of casings and welds was crucial to maximising structural integrity,” Harrison said.

“We made sure our platform, designed and manufactured by OptionX Bournedrill, could accept the 6m casing.” With the canopy tube arch successfully completed, Edge Underground has stepped away, paving the way for the next phase – the larger tunnelling works – to commence beneath the road.

Delivering eﬃciency without disruption

Despite the complexities of limited access and varying ground conditions, Edge Underground successfully delivered a safe, precise, and e cient microtunnelling solution with zero impact on road infrastructure above, and no disruption to the major rail service nearby. e project validated the e ectiveness of AdaptX technology and further cemented Edge Underground’s reputation as a leader in solving complex trenchless challenges through engineering excellence and machine adaptability.

Leading innovation in trenchless technology

Edge Underground’s ability to adapt and innovate sets it apart in the trenchless industry. As part of OptionX Group, it has the expertise, technology, and engineering capability to tackle projects previously considered impossible. While many contractors turn to OptionX Group businesses for customised solutions, Edge Underground has the advantage of full-time access to this expertise – allowing for seamless innovation and execution on every project.

S&Z Australia builds on legacy with new machinery

Heading into the new year, Melbourne-based Trenchless specialist S&Z Australia is expanding its oﬀering with new machinery and increased microtunnelling and horizontal directional drilling services.

S&Z Australia recently completed a microtunneling project in central Victoria which presented many challenges.

A sewer on grade was required to be installed through an area of cultural signi cance that prevented any excavation within the restricted area.

e tunnel bore consisted of a 250mm PE Pipe in rock 110m long that had to pass under a fast-running stream within a metre of the bottom of the stream.

e close proximity of the bore to the base of the stream posed a signi cant risk of the stream collapsing into the bore hole.

S&Z Australia General Manager Jim Pound said while there were challenges along the way, the team were able to successfully complete the job.

“ ere are no easy jobs, but we pushed through some tricky circumstances to complete the works as needed,” Pound said.

“Given the restriction of absolutely no excavation within the protected zone, there was no option to open cut any section or recover the head should the bore interfere with the stream. e S&Z Australia crew delivered a fantastic result under trying conditions.

“ e crew utilised their BohrTec 400 TBM, which is guided by a theodolite that constantly and accurately monitors the location of the front steer bore head, ensuring the bore head is exactly in the required location.”

e project was completed successfully on time and within budget, demonstrating how accurate and reliable the BohrTec 400 tunnel boring machine is.

In addition to S&Z Australia’s microtunneling capabilities, the company has continued to expand its o ering, with the acquisition of the AT Boretec MT 45 HDD Rock Drill.

is new unit is capable of installing pipe diameters up to 800mm and 600m in length, in all ground conditions.

“While this state-of-the-art unit has huge capabilities it is still quite nimble in comparison to other horizontal directional drilling (HDD) units and provides a practical and manageable footprint,” Pound added.

“We will continue to invest in leading edge technology and expand our o ering of trenchless options.”

Established in 2011 by John Noce and

A big year ahead for kwik-ZIP

Heading into its 25th year of operation, kwik-ZIP has had plenty to celebrate in recent months, with the WA-based company receiving some esteemed endorsements.

In August last year, kwik-ZIP’s HD series was successfully appraised against the Water Services Association of Australia’s (WSAA) product speci cation for casing spacers (WSA PS-324).

WSA PS-324 covers casing spacers used to facilitate the insertion and protection of carrier pipes when installed inside encasement pipes (casings).

Meeting this rigorous standard means that kwik-ZIP’s HD series meets speci cation requirements and quality assurances needed by the utilities the market.

While the entire kwik-ZIP spacer range is designed to meet WSA PS-324, the HD range is the third series of kwik-ZIP products formally certi ed as compliant with WSA PS324, along with the HDX and HDXT.

e HD, HDX and HDXT series spacers have no metal parts and are made from kwik-ZIP’s engineered thermoplastic blend with high exural strength, high temperature resistance, low co-e cient of friction, abrasion resistance and outstanding chemical resistance.

In other words, kwik-ZIP is delivering

highly durable spacers, backed by a WSA PS-324 certi cation. Fortunately, high quality does not have to mean complex.

Installation of kwik-ZIP spacers is simple and e cient, without the requirement of any special tools or setup equipment, nor is there any requirement to pre-wrap pipe.

e HDXR-103 spacers were used late last year, when contracting company Jonishan utilised kwik-ZIP HDXT-103 spacers to facilitate the slip-lining of a 914mm Sintakote® mild steel cement lined carrier pipe into a 1200mm reinforced concrete jacking pipe casing.

e work was conducted for the Upper South Creek treated water main.

is installation was part of the larger Upper South Creek (USC) project, which was implemented to improve environmental ows by transferring treated water from the new advanced water recycling centre (AWRC) to local waterways.

e AWRC and USC project are Sydney Water’s largest infrastructure investment in Western Sydney.

Whilst this installation was fully grouted, the HDXT spacers adequately supported the pipe and water for the life of the installation.

kwik-ZIP HDXT-103 spacers were installed to facilitate the slip-lining of a mild steel cement mortar lined (MSCL) wastewater pressure main into a RC Jacking pipe, running under a rail line for the Gosnells Main Pumping Station Wastewater Pressure Main Realignment project, which was run by utilities infrastructure experts Rob Carr.

Rob Carr Project Manager Marie Piette was thoroughly impressed with kwik-ZIP and its innovative spacers.

“ e MSCL pipes insertion is making good progress despite a challenging environment, with production e ciency notably enhanced by the simplicity of installation of the kwikZIP spacers,” she said.

Pezzimenti Trenchless were also among those praising kwik-ZIP’s products.

In one project instance, kwik-ZIP HDX90 spacers were installed to facilitate the slip-lining of an 813mm cement lined steel water main into a steel encasing pipe by Pezzimenti Trenchless.

“Whether the carrier pipe is plastic, GRP or heavy weight steel, kwik-ZIP has a spacer to do the job,” Managing Director Joe Pezzimenti said.

“ eir technical support and excellent customer service make using kwik-ZIP spacers an easy decision.”

Aside from spacer developments, the kwikZIP team have settled nicely into their new head o ce location in Bayswater.

e move was made to ensure the business is strategically positioned to service its customers.

e move has enabled kwik-ZIP to service WA clients more e ciently, while also allowing for increased inventory to be held on the west coast of Australia.

Existing or prospective customers are “always welcome to drop in and say hello at kwik-ZIP’s new facility,” wik-ZIP General Manager Paul Je reys said.

As well as seeing its products involved on projects in Australia and around the globe, kwik-ZIP also showcased its range at a number of events in 2024.

In Australia, the company exhibited its products at OzWater24 in Melbourne, followed up with a booth at the Australian Drilling Industry Association showcase in Perth.

As a Water Industry Operations Association (WIOA) member, kwik-ZIP also exhibited at the 2024 WIOA of Australia conference in both Bendigo and Tamworth, getting the chance to be in front of the water industry.

kwik-ZIP also exhibited at the 2024 No-Dig Live, which took place in Kenilworth, Warwickshire, UK from 1–3 October.

Leadership at all levels: Interﬂow’s bold plan

Effective leadership makes all the difference in the water sector. Interflow’s goal is to harness the leadership power of their people at every level of the business.

While many organisations focus their leadership programs on the upper and executive levels, Inter ow Managing Director Daniel Weaver sees success, and the concept of leadership itself, in a di erent way.

“Leadership is not about rank or hierarchy, or where you sit in the organisational structure,” he said. “It’s about creating a particular type of environment.”

In that environment, the individual and anybody working with them is encouraged to be their best.

And so, an e ective leader has powerful impact on the people around them, who feel good about going to work and are physically and emotionally safe.

Leaders also create a positive environment for those a ected by their work, such as the communities they serve.

With almost 700 people in the Inter ow

team, spread across various roles and in numerous geographies and locations, Weaver believes each and every one of them has a role to play in shaping the work environment.

His passion is around ensuring every individual is clear on what it takes to be a great leader at Inter ow and has the opportunity and the tools to lead in their capacity.

“ e potential of our people is limitless,” Weaver said. “It’s possible that some of them have not had opportunities in leadership development, in the past. Some of our best leaders right now are likely self-made.”

“So, I think, in terms of the people at Inter ow, the best is yet to come. My goal is to help them reach their full potential.”

Leadership program shaped around everyone

Inter ow’s leadership program, now in its second year, is focussed on boosting the

leadership capability of individuals at all levels, and particularly those in eld-based roles.

It was developed after a period of research to really understand Inter ow’s people and customers. e output of that research convinced Weaver that the only way to ensure permanent and positive change was to empower those people who had the greatest capacity to shape the everyday work environment. ose people are out in the eld, working on water projects across Australia and New Zealand.

What’s unique about Inter ow’s program is that it was built by the team, for the team through a solution design process. ey brought together people from every level of the business to understand what it means to be a great leader at Inter ow.

It was clear from the design process that tools and approaches needed to be customised to the way people work and where they work,

There are almost 700 people in the Interﬂow team today.

which for many includes challenging and highrisk environments.

Also crucial was that leadership be hardwired into every people process, policy and system, so that it becomes simply ‘how we do things’ and not an add-on.

e resulting program centres around twoday workshops which bring together around 25 current or potential leaders from across the organisation to Sydney to explore their leadership potential.

In the rst year, Weaver himself rang each attendant to invite them, personally explaining the purpose, goals and value of the program. Although the practice of personally inviting each participant has become more di cult as the program has grown in scale, it was important during the rst year, to set the tone.

Now, as there is a far-reaching understanding of how it works and why it exists, people are reaching out to be included.

“I would love to still be able to have those conversations, but it says more that I no longer need to,” Weaver said.

“ e ripple e ect we’ve seen from people applying what they learn every day is that there’s now a real understanding of the importance of learning to be a great leader.

“It means people want to take part and leaders want to support their people to take part.”

Part of the value of having 25 people together in a room, all from di erent regions and with varying levels of seniority, is the group’s diversity of knowledge and experience and the ability to connect.

“If you put people in a room and they’re all from one team, you’ll get one common set of thinking,” he said.

“But if you have people from di erent teams, it disrupts that groupthink. ey connect with and learn from each other.

“ ey’re coming together to start or continue a journey of leadership, which is about the collective Inter ow environment. But it’s also about developing the individual and about connecting with and learning from peers from other places, people you didn’t previously know.”

Four circles of leadership

e leadership workshops are based around a model Weaver describes as “Four circles of leadership”, which focusses variously on leading people and teams, leading work and leading oneself.

Participants evaluate their strengths in each area, as well as their potential for growth, which introduces a powerful mix of validation and self-awareness.

“For some, it’s like, ‘Aha, I do that. I do lead in a balanced way.’,” he said.

“For others, they realise they’re spending 95 per cent of their time leading the work, leaving them very little time to focus on their people, or on themselves.”

A

work in progress

At the end of the two-day session, participants provide feedback on their experience and that informs enhancements for future programs.

“We are basically empowering the business to decide whether the program continues or not,” Weaver said. “As long as the business says this program is helping, it will continue.”

After just two years, Weaver said the program is already having tangible e ects, including strengthening resolve around Inter ow’s stated purpose – “to improve the lives of the people we work with, the communities we serve and the environment we work in, for generations to come” – as well as improvements in people engagement and retention and attracting the right types of people with the very best attitudes and approaches to work.

“I’ve always been a rm believer that answers to all challenges lie within,” he said.

“It has never ceased to amaze me what you can learn, solve or create when you get 25 people from the business together.

“Seventy to 80 per cent of our business is based in the eld, so our people in the eld can all have an impact on the work we do, on the people around them and on the local communities. ey can all be leaders, and my goal is to give them the opportunity, mindset and tools they need to do that.”

Organised in partnership with the Australasian Society for Trenchless Technology (ASTT), No-Dig Down Under has grown over the years to become the second-largest no-dig technology event in the world and is a ‘must-attend’ for all industry professionals.

is year’s event will return to the Melbourne Convention and Exhibition Centre and take place from 17–18 September.

No-Dig Down Under will feature an exciting technical program, inviting speakers from around Australia and the globe to present papers covering case studies, new and emerging technologies, challenging projects and environments, industry skills and training, risk management and more.

An extensive social program will also take place, including the much anticipated ASTT Gala Dinner and Awards Evening, providing attendees with networking opportunities in a variety of settings with industry professionals.

With so much in the works, it’s no

wonder that some of Victoria’s leading water corporations, Yarra Valley Water (YVW), Barwon Water, and Greater Western Water (GWW), are rallying behind No-Dig Down Under 2025.

United by a commitment to sustainable infrastructure solutions, the event o ers the perfect platform for these entities to engage with cutting-edge technologies, exchange insights and explore best practices in environmentally conscious trenchless methods. YVW utilises trenchless technology on a range of its new infrastructure and upgrade projects. is includes microtunelling under the Hume Highway for the Mount Fraser water pipelines which will service Melbourne’s growing northern suburbs; renewing over 100-year-old water mains in heavily tra cked areas through sliplining, including sections of the M4 water main renewal project; and tunnelling 40m deep main sewers to provide additional capacity and minimise sewer spills to the environment.

“Trenchless technology is essential as we work to avoid and minimise impacts from our water and sewer infrastructure construction,”

YVW Divisional Manager, Asset Delivery Sally Crook told Trenchless Australasia

“ is technology helps us achieve better customer outcomes, safeguard cultural heritage and protect trees and vegetation.”

For YVW, No-Dig also represents an exciting opportunity for learning.

“No-Dig Down Under provides a unique opportunity for utilities, manufacturers, suppliers, designers and constructors to come together and share their experiences,” YVW Divisional Manager, Asset Field Services Mark Edwardson said.

“Yarra Valley Water’s proud to support this event to generate new possibilities to achieve excellent community and environmental outcomes.”

Barwon Water also has its nger on the pulse when it comes to trenchless methods like sewer relining and horizontal directional drilling (HDD). e water corporation has rolled out these solutions in key projects.

ese solutions have helped Barwon to minimise the destruction of habitat and reduce carbon emissions, creating a healthier environment.

Similarly, GWW is no stranger to utilising trenchless technology in its infrastructure projects, particularly in environmentally sensitive locations. e water corporation uses trenchless methods to reduce noise, dust and impacts on tra c.

e water corporation’s recent projects have bene tted from trenchless solutions that minimise disruption to the public.

GWW’s ongoing commitment to technological advancements is key to its 2030 strategy, which focuses on delivering long-term value for customers and supporting communities to thrive. e corporation’s attendance at No-Dig Down Under is evidence of this ethos at work.
