Editor’s letter David Convery

A

s was mentioned in our previous edition, Trenchless Australasia was recently acquired from Great Southern Press by Prime Creative Media, so this edition of the magazine is noteworthy for being the first to be produced under the new banner.

In the short months since the acquisition, there have been many discussions about the future direction of the magazine and how it can continue to be a voice for the industry, and I’m happy to say there’s plenty to look forward to as the brand and its new owners continue to get acquainted.

Trenchless Australasia will continue to work closely with the ASTT and the wider sector to bring readers the latest project, product and industry news and I’d like to take this opportunity to thank everyone for their continued support.

The magazine is now better resourced than it has ever been, and the willing participation of our advertisers and audience has made the change to a new owner almost seamless.

Although the publisher may have changed, so much of the trenchless content our readers enjoy can be found throughout this edition.

Some noteworthy entries in this magazine include our cover story on McConnell Dowell’s microtunnelling exploits in New Zealand in the Projects feature, Primus Line’s rehabilitation work in our Queensland regional feature, and a look at how Interflow is making water main renewals easier than ever in our Rehabilitation & Repair feature.

Importantly, this edition also contains a preview of the upcoming No-Dig Down Under event, taking place in Sydney this October. This is an immensely important event for the trenchless industry and the largest of its kind in Australasia, so if you haven’t already, start planning your attendance.

I can say from experience that the

previous No-Dig was a tremendous success and you would be hard-pressed to find a better showcase for the trenchless industry anywhere in the world.

At the time of writing, the last remaining event sponsorship, a Gold tier spot, is up for grabs, so get in quick if you still wish to be on board. Interested parties should contact Nick Lovering at nick.lovering@primecreative. com.au to secure the final spot as it definitely won’t be available much longer.

One more thing to note is the change to the ASTT membership system. This is a new initiative from the society and all the details can be found on page 77.

I and the rest of the Trenchless Australasia team look forward to seeing everyone in person at No-Dig in Sydney. Stay safe until then.

12 TRENCHLESS AUSTRALASIA JUNE 2021

elcome to the June edition of the Trenchless Australasia Magazine 2021.

In this edition you will notice some changes: Firstly, I have been elected as the new ASTT President and I hope to serve you, our members, and the industry to the best of my ability. I have been a Councillor for seven years and the Vice President for the last two of those.

I’m approachable and I encourage discussion and collaboration.

Secondly, our trusted media partner, Great Southern Press, has been acquired by Prime Creative Media who will take us forward and support the society with the key items of this informative magazine and our No-Dig conferences. I’d like to personally welcome Prime onboard and having worked with them for a few months now I can confidently say we are in good, experienced hands.

As we turn the treacherous “pandemic/ fires/floods” corner, and we grapple with the new normal that sees all levels of government committed to stimulating the economy. This stimulus greatly extends to infrastructure where our beloved trenchless industry will benefit.

I look forward to the busy times ahead as the infrastructure is planned, designed, procured, delivered, commissioned and maintained. It is a time to seek help from your society and collaborate with your peers.

We welcome conversations via all mediums on how we can help promote the trenchless industry.

My goal for our ASTT: • Awareness: there is a broad understanding that our technology exists.

• Support: planners considering our technology know where they can seek advice.

• Reputation: our industry emerges with a reputation that reflects the hugely successful projects that we complete.

There is an understanding of the heightened risk; however, these days, the risk is adequately managed and controlled.

• Collaboration: we share our experiences and our knowledge be it via our

conferences, our Special Industry Groups and our webinars so that we all grow and learn of new technology and how challenges were overcome.

A couple of updates on the ASTT: • Our No-Dig Conference is shaping up to be a huge success. I’m told the technical papers are coming together well and the conference booths are almost sold. Look out for the Training Courses that we will be running.

• Our webinars are going well; however, we are always looking for good speakers and good content. Please reach out if you would like to present and/or we encourage you to attend on the screen.

• Our Special Industry Groups are going well, and they are achieving their respective industry goals. Again, please reach out if you would like to form a group to achieve something for our industry. The ASTT will happily support you with resources for beneficial industry outcomes.

• The ASTT council is working on our strategic plan actions, which will continue to improve member benefits, better support the industry and generally improve the way we interact and engage with the trenchless community.

Finally, I’d like to thank Chris Frangos our outgoing President. Chris’ career has taken a turn away from the trenchless industry and he thought it would appropriate to resign and let the ASTT be led by industry people.

Chris tells us that his time in our industry will be fondly remembered by him. His time in the trenchless industry and in the executive of the ASTT was full of rewarding milestones and achievement.

He wishes us the best and he will always reflect on the loyal friendships formed within our industry and remember what a great bunch of professionals make up the technically challenging industry that we call “trenchless”.

Ben Crosby ASTT President bencrosby@bamser.com.au

From the ASTT Secretary Jeff Pace New Members On behalf of the ASTT, I extend a warm welcome to the following new members.

Silver Corporate Members – Australia Nester Ioannou - Melbourne Water Dora Wednesday - Finlease Shane Curren - Eco Relining Supplies Simon Balemi - JB Trenchless Pty Ltd Individual Members – Australia Paul Propper - King & Wood Mallesons Scott Phillips - South East water Corey Hammond - Sherlock Drains Jackson Bugeja - Pipeline Watertech Morgan Edmunds - UVR Hire Tertiary Education Institute – Student Lucas Vieira - UNSW Individual Members – New Zealand Stephen Walker - Interflow Frank O’Callaghan - Iplex Pipelines NZ ASTT New President After five years at the helm, Chris Frangos has decided to not re-nominate for the role as your ASTT President. Chris was finding his work commitments are taking up a considerable amount of his time and that he could not guarantee that he could give as much attention and time to the ASTT as he would have liked.

Chris will remain on as the Immediate Past President and Interim Councillor.

To this end, Council endorsed Ben Crosby as the new President of the ASTT. Ben took over the role of the Queensland Councillor following the resignation of Andy Krumins back in May 2014. Ben was elected Vice President also in 2017 and has been extremely active in Queensland.

ASTT 2021 Council update Following the AGM on 25 March, your Council representatives are as shown under.

ASTT COUNCILLOR REPORTS New Zealand – Blair Telfer Tēnā koutou katoa. The recent central government stimulus funding in infrastructure has been a great boost for our specific industry and the country as a whole. However, it has also shown up a couple of key issues, one being the historical underspend in infrastructure and the second being the lack of trained personnel to undertake the volume of work that currently exists.

This is a common theme I hear from most in our industry: it’s great, there’s good work out there but I can’t find enough trained staff to do it all. I believe we all have a role and a duty to play in this space. There are a number of training opportunities out there in trenchless technology, so once you’ve found the right person, invest in them, get them trained and lets set our industry up for the next generation.

Mā te wā.

Western Australia – Trevor Gosatti Rob Carr to deliver sewer extension project in Western Australia incorporation trenchless technology Rob Carr was awarded the contract to deliver the design and construction of the Quinns Main Sewer Extension for the Water Corporation in Western Australia. The Rob Carr team is looking forward to working closely with its design partner, SMEC, and its client, Water Corporation WA. The project involves the installation of 1,931 m of DN1800 sewer main (1167 m via microtunnelling), 6 m deep and 25 m deep vortex chambers, and six other sewer manholes. The Quinns Main Sewer Extension will allow conveyance of wastewater flows from Ellenbrook (Barrambie Way), Jandabup and Neerabup (Wanneroo Road) main pump stations into the Alkimos wastewater treatment plant, as the existing wastewater conveyance infrastructure does not have sufficient capacity in the long-term.

Western Power Network Renewal Undergrounding Program Pilot Western Power renew and upgrade the distribution overhead network when assets are coming to the end of their service life. Replacement of the overhead network with a new underground system is more cost effective for Western Power through the Network Renewal Undergrounding Program Pilot (NRUPP), if the local government authority covers the cost of replacing the overhead service connection with underground.

The Town of Victoria Park and the City of Canning councils have recently approved a NRUPP partnership with Western Power, to deliver an estimated $15.6 million of local power infrastructure investment covering St James, Bentley and East Victoria Park. These works are scheduled for completion in December 2022.

Victoria – Justin Shepherd Recently elected as ASTT Victorian Councillor, I’m excited to be in the role during this busy time for the trenchless industry in the state, with numerous trenchless opportunities associated with the economic recovery infrastructure stimulus.

Here are a few recent projects from some of ASTT’s member organisations: The North East Link Project has begun a number of early works packages to relocate Melbourne Water and Yarra Valley Water (YVW) utility assets. Bothar Boring and Quinn Civil have commenced work on the Yarra East Main Sewer Works, a major sewer relocation scheme requiring three pipe-jacked tunnels of 1,500 or 1,800 mm ID totalling 1,800m to be built using three mini TBM’s.

In the city, Rob Carr achieved practical completion on City West Water’s Stage 2A CBD Sewer Augmentation – Lonsdale St Sewer Upgrade, completing 900 m of 1,499 mm OD GRP sewer installation over two pipe-jacked drives of 550 and 350 m length in the CBD. The project was completed in November 2020 and achieved finalist status in the AWA Victorian Water Awards.

Melbourne Water has commenced the tender process for the Hobsons Bay Main Sewer Upgrade Project – a project requiring a duplication pipeline to be installed using trenchless methods below Hobsons Bay to ensure the continued reliability of Melbourne’s sewage network.

New South Wales – Matthew Boyle NSW is ramping up the infrastructure spend across all regions and opportunities are presenting themselves for many of our NSW members. Traditional asset owners are looking to new ways to construct and maintain existing assets and many members I have spoken to have been able to develop trenchless solutions for these organisations.

It’s not all roses though, with many members facing challenges due to increase demand overseas and reduction in shipping making material such as plastic, steel and timber more expensive and harder to come by. Challenges are also be faced with staffing and a reduction of casual labour making the market movement in some regions fever pitched.

From the ASTT, planning is underway for No-Dig Down Under in our own backyard and I would encourage all members to get in early for your tickets, it looks like it will be a cracker.

16 TRENCHLESS AUSTRALASIA JUNE 2021

For 60 years McConnell Dowell has led the way in trenchless technology across Australia, New Zealand and South East Asia.

Our multi-disciplinary creative and innovative approach has seen us: • Introduce jacked shield tunnel construction into Singapore and Australia in 1975 and 1979 respectively; • Pioneer slurry shield microtunnelling for the first time outside Japan in Singapore in 1982 and go on to establish slurry shield microtunnelling in Australia and New Zealand in 1984 and 1987 respectively; • Set and regularly surpass southern hemisphere pipejacking drive length records in the 1500 to 2550mmID range; • Differentiate with Direct Pipe® technology and set world records for single drive length twice (1929m in 2018 and 2021m in 2020).

Embracing Engineering, Technology and Innovation to provide a better life - that’s Creative Construction.

NEWS IN BRIEF

kwik-ZIP gets tick of approval on spacers The Water Services Association of Australia (WSAA) has once again certified kwik-ZIP’s HDX Series casing spacers. The spacers are used to maintain the position of a carrier pipe in a water or sewer main within an encasing pipe for pipe-in-pipe applications like sliplining and cased crossings. The system can be used for medium to heavy weight pipe materials including steel, ductile iron, GRP, FRP, concrete, PVC and PE and is suitable for both pressure and non-pressure pipelines in grouted and un-grouted installations. The HDX casing spacers use a segmented design that allows the system to be used on a range of carrier pipes from 100 to 1,668 mm OD. The components of the spacer are manufactured from injection moulded inert engineering thermoplastics that incorporate low friction high abrasion resistant wear pads, attached to load sharing runners. The WSAA provides member organisation and the general urban water industry with best practice codes and standards to help promote the use of fit-for-purpose productions and solutions. The WSAA appraisal processes require products to be re-certified every five years.

WaterNSW selects ARRP construction partners Diona and Abergeldie have been named WaterNSW’s new construction partners for its Asset Renewals and Replacements Program (ARRP). The $80 million program will see the partners deliver multi-disciplinary packages across regional New South Wales and Greater Sydney, including civil, structural, mechanical and electrical capital works and rehabilitation.

The contract will be delivered over a period of five years, with an option to extend another three years. Abergeldie CEO Mark Bruzzone says the company’s previous experience with WaterNSW will ensure the program is delivered safely and on time. “We are looking forward to continuing to grow our collaborative relationship with WaterNSW,” he says.

“This framework will provide long-term employment opportunities for both WaterNSW and Abergeldie in regional NSW. At Abergeldie, we deliver the complex infrastructure needed to build better communities and we are excited to continue on our mission with WaterNSW.” AssetReady, a joint venture between WSP and SMEC, was recently appointed as the project’s Engineering Design Partner.

NSW proposes Australia’s longest road tunnel The NSW Government announced it is examining the prospect of connecting two proposed tunnels into a longer tunnel as part of the Greater Western Highway upgrade between Katoomba and Lithgow. NSW Minister for Regional Transport and Roads Paul Toole says linking the two tunnels already determined for Blackheath and Mount Victoria would deliver a more reliable connection through the Blue Mountains.

“The NSW Government knows how important this upgrade is to the people who use the Great Western Highway every day and in improving connections between Sydney and the Central West, which is why we committed $2.5 billion to deliver a once-in-a-generation upgrade to this key corridor,” he says. “As part of this upgrade, we’ve already committed to a 4.5 km tunnel to bypass Blackheath and a 4 km tunnel underneath Victoria Pass, one of the steepest roads in NSW. We’re now investigating connecting those two proposed tunnels into one longer tunnel. This would be a history-making project, delivering Australia’s longest road tunnel and allow motorists to avoid all the current pinch points from Blackheath in the east to Little Hartley on the western side of Victoria Pass. It will also mean less disruption for local residents and businesses during construction and a smoother, safer journey for those travelling underneath Blackheath and Mount Victoria as well as those travelling above.”

The government said construction on the Great Western Highway Upgrade is expected to start at Medlow Bath in 2022, with the full upgrade expected to be completed within 8 to 10 years.

NEWS IN BRIEF

Complex works complete Rob Carr recently completed infrastructure works in difficult ground conditions for the Fulton Hogan Delplant Beca (FHDB) Joint Venture in Victoria. Rob Carr employed its Iseki slurry pressured balanced machines to install 98 m of 470 OD GRP pipe under Evelyn Street and Fletcher Road in Frankston in record time for FHDB. The works were undertaken in water charged and soft silty sand ground conditions that had seen two previous contractors’ efforts to complete the job prove unsuccessful. Rob Carr says FHDB had entrusted Rob Carr only with the works and both groups had collaborated to ensure the operation was completed successfully.

“Given the works’ criticality, Rob Carr had one of its most experienced TBM operators on the job Jason Shirtcliffe, who, along with his crew, used every ounce of their experience to ensure the completion of the line,” the company says.

New utility appoints inaugural MD Maree Lang has been appointed as the inaugural Managing Director of Greater Western Water.

Officially launching on 1 July 2021, Greater Western Water is an integration of Western Water and City West Water in Victoria, with the move designed to ensure better water services for customers in Melbourne’s fast-growing outer west. Ms Lang is currently Managing Director of City West Water and has previously held executive roles with Melbourne Water and Chemistry Australia, as well as other senior consulting roles.

“Everyone at Western Water and City West Water will be part of Greater Western Water – it’s a unique opportunity to bring together our different experiences, backgrounds and skills to co-create a new organisation that reflects our equally diverse communities,” says Ms Lang. Western Water Chair Andrew Cairns says the appointment was a great outcome for the new utility. “Maree brings a wealth of experience and achievements to the role and will champion the culture and values that we know are important to our people and communities of the west,” he says. Western Water Managing Director Jeff Rigby will remain in his role until 30 June 2021, at which point he will become part of Greater Western Water’s executive leadership team. All existing staff from both organisations will be transferred to the new company, and $500,000 has been invested in planning upgrades to convert Western Water’s Sunbury office into a Greater Western Water hub.

Sydney Metro West receives major planning approvals Tunnel boring machines could be in the ground by the end of 2021 after the Sydney Metro West project was granted significant approvals.

The Sydney Metro West project concept, from Westmead to the Sydney CBD, as well as station excavation and tunnelling between Westmead and the Bays was granted planning approval in March, which New South Wales Minister for Planning and Public Spaces Rob Stokes called a huge step forward.

“This city-shaping project will have a target travel time of about 20 minutes between Parramatta and the CBD, cut crowding on three major train lines and take tens of thousands of cars off the road every day,” he says. “It will create more than 10,000 direct jobs and around 70,000 indirect jobs, while delivering a vital boost to the local economy.” The project will include 24 km twin tunnels which will link new suburbs to rail for the first time, including new stations at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays, Pyrmont and the Sydney CBD. The first of three tunnelling contracts is expected to be awarded in the middle of this year and, due to its size, the planning approvals process for the project is being done in stages. The NSW Government committed $6.4 billion over four years to Sydney Metro West in 2019.

Queensland upgrades taking state to next level Significant infrastructure projects incorporating trenchless technologies are in progress all over Australia’s Sunshine State to keep pace with strong population growth and a consistent tourism industry.

Cross River Rail Cross River Rail is one of the highest profile and most expensive projects currently underway in Australia, with an estimated price tag of $5.4 billion and a label as the largest infrastructure undertaking in Queensland’s history. Constrained by a single river crossing and a rail service close to capacity, Cross River Rail will deliver a second river crossing to Brisbane’s public transport system, integrating with new roads and bus services to enable a better and more efficient network for the state’s southeast.

A new 10.2 km line from Dutton Park to

32 TRENCHLESS AUSTRALASIA JUNE 2021

Bowen Hills will connect the northern and southern rail networks in Brisbane’s CBD, with 5.9 km of the alignment being tunnelled under the Brisbane River. The project is employing the use of two tunnel boring machines (TBMs) built by Herrenknecht, running 164 m long with cutterheads weighing 106 t and measuring 7.2 m in diameter.

In January 2021, Cross River Rail’s first TBM, named ‘Else’, moved underground to its launch position in Woolloongabba before commencing tunnelling later in the month, with TBM ‘Merle’ following shortly after.

From Woolloongabba, the TBMs will

tunnel under the river and break through to Albert Street station at a depth of 31 m in mid-2021 and continue to Roma Street before emerging at the project’s northern portal at Normanby. The machines will tunnel through 20 to 30 m of hard rock each day, with a crew of up to 15 people working on them at any one time, and will line the tunnel walls as they go with 25,000 precast concrete segments weighing 4.2 t each.

Three new stations on the Gold Coast line at Pimpama, Helensvale North and Merrimac will also be constructed, and the project is expected to be operational in 2024.

UNDER QUEENSLAND

Brisbane Metro Brisbane’s other major transport project is Brisbane Metro – a $1.2 billion endeavour to construct a new tunnel under Adelaide Street and rework the Victoria Bridge to include two-way cycling lanes, three lanes for public transport and more pedestrian space. The project is being delivered by the Brisbane Move consortium, consisting of ACCIONA Construction Australia Pty Ltd and designlead, Arup Australia Projects Pty Ltd, which has experience with similar projects including the Toowoomba Second Range Crossing and Cross River Rail.

Now underway, the first stage will provide a 21 km service connecting 18 stations along dedicated busways between Eight Mile Plains and Roma Street, and Royal Brisbane and Women’s Hospital and University of Queensland. In January, it was announced the proponents expect tunnelling works to begin later in 2021.

Water pipeline rehabilitation In early 2021, Seqwater completed rehabilitation works on one of the Sunshine

Coast’s most important bulk water pipelines.

The company had identified the need for rehabilitation after inspecting a 2.5 km tunnel housing the pipeline, with more than 60 t of rock and soil chipped away and removed from the underground tunnel to protect the asset.

The tunnel is located beneath the Blackall Range and houses a pipeline that transports water from Baroon Pocket Dam to the Landers Shute Water Treatment Plant in Palmwoods.

Seqwater Asset Engineer Daniel Roche says inspections of the tunnel, carried out by geotechnical and civil engineers, is what found several loose and cracked rocks that threatened to fall and damage the pipeline.

He says advances in technology helped make it easier to detect potential issues in the tunnel and solve these issues before devastating impacts had been made.

“For example, we can now use laser scanning to create a 3D model of the tunnel which helps identify and record any cracks appearing in the tunnel that might not have been there before or movement within the rock,” says Mr Roche.

“In order to maintain this critical link, regular inspections and repairs will be carried out in the tunnel, to ensure it remains a safe environment to access and work in, with minimal risk of damage to the pipeline.”

In the 1980s, the tunnel had been excavated through sandstone using drill and blast techniques and had deteriorated over time due to natural weathering. Seqwater Dam, Recreation and Catchment Operations Coordinator Phil Benson says small teams worked together to manually remove the rock using pry bars, then loaded the rock into a small cart fixed to a rail to transport it out of the tunnel.

“As the project neared completion, the team was having to walk more than two kilometres into the tunnel to excavate the rock, load the cart and head back,” says Mr Benson.

The pipeline, which is now secured, is not only important for the Sunshine Coast but stands as a critical component in southeast Queensland’s water grid with its ability to transport 180 ML of water to the treatment plant.

Primus Line breathes new life into historic trunk main in Brisbane One of Brisbane’s oldest and most important drinking water pipes runs under Ann Street in the bustling business and nightlife district of Newstead and Fortitude Valley. Earlier this year, Urban Utilities completed a multi-milliondollar rehabilitation project on this 130-year-old pipeline.

Rehabilitation work took place almost entirely without disruptions for traffic and residents.

34 TRENCHLESS AUSTRALASIA JUNE 2021

Small excavations are sufficient for the installation.

W

ith the use of the trenchless technology Primus Line®, the project is expected to extend the life of the pipeline by at least 50 years, providing an economical solution with minimal impacts to traffic and nearby businesses and residents.

The Ann Street pipeline is a cement-lined, cast iron pipe, and helps to supply water to the city centre and the inner-city suburbs.

During the morning and evening peak consumption periods, about 500 L of water per second flows through the pipe.

Thousands of vehicles a day roll along the four-lane road, which is one of the

busiest roads in Brisbane’s central business district, and businesses and bus stops line the traffic route.

Replacing water mains in heavily congested urban environments can be a costly and disruptive process, so in this case trenchless technology was the key to success.

Given the location of the pipe, Primus Line was chosen as it could pass through several bends in the pipe and be installed using a few small pits, to minimise the impact on traffic.

Planning As Primus Line is a flexible stand-alone pipeline, which is installed with an annulus

UNDER QUEENSLAND

gap, it can withstand the operating pressures of the water main, but not the external loads from the traffic on the road above.

The project at Ann Street was preceded by a detailed condition assessment of the host pipe and economic evaluation in order to ensure the existing pipeline could withstand external loads in the future. The results showed that the pipeline had sufficient load bearing capacity to allow the use of a semi-structural lining system such as Primus Line for the desired service life of at least 50 years.

The perfect choice Due to its unique three-layer structure, the Primus Liner combines flexibility with extremely high material strength. As a selfsupporting pressure pipe liner independent of the old pipe, it absorbs the entire operating pressure, while the old pipe merely functions as a conduit.

In accordance with ISO 11295, Primus Line is an independent pressure pipe liner capable on its own of resisting without failure all internal loads throughout its design life. It has the ability to negotiate bends of up to 45 degrees, allows for seasonal movement of the pipeline and ensures the required operating pressure of up to 11.3 bar.

Despite the reduction in cross-section of the DN 600 pipe, flow calculations showed the client that the installation of a Primus Line DN 500, with its low friction coefficient of only 0.028, would still provide the required flow.

Before the start of the project, a large- scale trial with a length of 350 m was carried out with the Primus Line system – developed and produced in Germany. In a single day, the prefolded liner was pulled into the 350 m field trial section of the Ann Street trunk main, formed into its circular shape with compressed air and successfully connected to the pipeline network.

Start of the major project The successful completion of the trial allowed for the commencement of the Ann Street project, where detailed design and construction planning was performed in 2019

by Urban Utilities. The initial stages of the project also involved cleaning and prepping the existing pipe to make it suitable for installing the liner, while the installation phase began in mid-2020 and was completed in early 2021.

Most of the work took place at night and the small construction pits were closed during the day with large steel plates, to allow traffic to continue to flow. The entire project was

required necessary tools and spare parts in stock to perform Primus Line installations and possible repairs and maintenance in-house.

The Primus Line team provided engineering support and accompanied the beginning of the measure with a supervisor. Four installation sections were necessary to rehabilitate the 2.2 km long pipeline section, with the Primus Line system DN 500 PN 16 used to rehabilitate the DN 600 water pipeline.

Primus Line delivered the four liner sections pre-folded in a U-shape and wound onto drums. The liner insertion into the old pipe was done with a winch and in the process passed through some additional smaller intermedia pits to reinstate valves and offtakes. The liner was pulled through these pits and cut afterwards to install the Primus Line connectors and the necessary valves and t-pieces Special DN 500 connectors with a DN 600 flange were used to ensure the connection to the flange on the host pipe while keeping the pits as small as possible.

A pressure test concluded the successful installation before the main was disinfected and returned to operation.

PROJECTS

McConnell Dowell gets creative on NZ storage pipeline McConnell Dowell are closing in on completion of the St Marys Bay Area Water Quality Improvement project in Waitemata Harbour, Auckland. The complex project involves the construction of a new stormwater storage pipeline which will help provide a better life for people, birds and marine life in the region.

The London Street shaft under construction.

T

he St Marys Bay Area Water Quality Improvement project secured another win with the completion of the last tunnelling drive at the end of 2020. Hinehōaka, the project’s microtunnel boring machine (MTBM), successfully completed more than 1 km of microtunnelling in less than six months.

The 1,120 m storage pipeline, which includes a marine outfall, was constructed in three separate tunnelling drives using pipe-jacking methods.

The new pipeline will reduce wastewater overflows to St Marys Bay and Masefield Beach by 95 per cent.

The high flows after rain events will be stored in the new larger capacity pipeline and pumped back into the sewer network for treatment when there is capacity. As well as reducing overflows, once complete the new marine outfall will discharge to a location far away from places where people swim.

Two shafts were constructed in council parkland at the bottom of the cliff face to accommodate each tunnelling drive and a third shaft needed to be constructed in the narrow streets around St Marys Bay. This shaft was carefully and cleverly designed to be able to retrieve the MTBM from a 3.8 m diameter shaft, 25 m below ground. ”We couldn’t have asked for a better result after the completion of our last tunnelling drive at the end of 2020,” says McConnell Dowell Senior Project Engineer Grant Maclean .

“We set a bold target of getting the drives finished and machine out of the ground before Christmas, so it was a great team effort to complete it in time. The team comprised of some really experienced members, as well as some new ones who were eager to learn.

“It was great seeing them help each other out and pass on some of that knowledge to the younger ones. The crew should be proud of what they achieved, especially finishing the job in a highly sensitive area, with almost no noticeable effect to stakeholders.”

Responding to challenges Each tunnelling drive had its own unique challenges but one of the major challenges the project team faced was tunnelling very close to, and underneath, restored villas worth millions of dollars in one of Auckland’s oldest suburbs. To mitigate stakeholder issues and concerns, the project set up a ‘SiteHive’ unit to collect data while the MTBM was operating.

The unit continuously collected noise, dust and vibration monitoring readings from the worksite and this data helped proactively manage consent compliance, as well as record the impact of the operations. When noise reached predetermined levels a photo and sound recording were taken to capture the activity onsite.

This constant monitoring meant the team could ensure construction activity operated within the consent conditions and any exceedances were investigated to see what could be done differently to ensure compliance in the immediate future.

Another technical feat on this project has been the design, construction and sinking of the marine outfall pipe. The outfall, constructed by McConnell Dowell’s New Zealand marine team, had been cleverly built to withstand the 12-hour pipe-tow journey from Kaiaua, Firth of Thames to Auckland.

What made this significant milestone a challenge was the on-water installation of the ballast blocks. Although on-water installations have been done before, the Creative Construction™ difference on this project had been the design and construction of the custom-made frame attached to the side of the barge.

This meant there was less pipe bending during the installation, while ensuring sufficient space on the barge to store the 70 ballast blocks and the crane that was carrying out the operation.

Once the ballast blocks were installed, the 460 m HDPE pipe was floated around from its temporary mooring off Westhaven Marina to its

final position adjacent to Masefield Beach.

Although the sinking of the pipe was an effortless seven-hour procedure, the accuracy of the sinking was mainly due to the measurements taken by site engineers two days prior.

Starting from 3am, the team started measured the pipe every hour for two days to see how it expanded and contracted in different temperatures and they noted the pipe dimensions that were recorded at the beginning of the day were different at the end of the day.

By using these calculations, they could give a close-to-perfect hypothesis of where the pipe would land at completion of the sinking.

As a result of these studies, there was only a slight discrepancy of 50 mm off the predicted landing. According to McConnell Dowell Project Manager Matt Beswick, sinking the pipe and connecting it to the end of the newly built stormwater tunnel was quite a technical feat.

“It had been twelve months of meticulous preparation and design. Sinking the outfall pipe was very impressive and precise work requiring both large scale machinery and human involvement, and we’re very proud of everyone who worked on this project,” he says.

Health and wellbeing has also been a huge focus on this project, as all three tunnelling

drives were carried out by the team working in shifts over a 24-hour, five days per week work period. To educate the team around mental health, McConnell Dowell invited Mates in Construction, a program aimed at improving mental wellness and reducing suicide in the construction industry, to run sessions onsite with the crew.

The St Marys Bay Area Water Quality Improvement project is the first McConnell Dowell site and fourth site in New Zealand to be Mates in Construction accredited.

The scope of works includes: • Building a new 1.2 km long, 1.8 m diameter stormwater storage pipeline and 500 m of additional wastewater pipeline connections from 900 to 1,050 mm internal diameter.

• Constructing three shafts at Pt Erin, St Marys Road Park and the corner of London and New Streets.

• Performing three tunnelling drives to connect the shafts (and manholes) and create a tunnel to the pump station and out to the outfall location in the Waitemata Harbour.

• Assembling a 468 m long 1,600 mm diameter high-density polyethylene (HDPE) marine outfall assembled in Kaiaua, Coromandel then towed 90 km to Auckland.

• Building a new pumping and screening station and odour control unit in the Pt Erin Park shaft.

Construction began in January 2020 and is scheduled for completion in mid-2021.

The project would see the installation of 700 m of pipeline for a 150 mm reticulated sewer, with Adept Civil continuing its track 38 TRENCHLESS AUSTRALASIA JUNE 2021

record of successfully completing highrisk jobs.

Adept Civil was tasked with installing approximately 170 m of 180 mm PE pipe after drilling with a 350 mm pilot head. The company used the Vermeer Axis GB812 laser-guided boring system for the project due to its precise drilling capability and vacuum extracting method which eliminated any spoil left in the bore hole.

To minimise the environmental impact of the boring works, these were located in the Vic Roads reserve adjacent to the Geelong Ring Road. One of the main challenges encountered during drilling was the varying ground conditions in the region; however, Adept Civil was able to overcome any difficulties due to the many cutting tools available for the Axis machine and the experience of the team.

Committed to safety the environment Adept Civil is known for its complete commitment to safety, both of its employees and the general public. Through its in-house training and meticulous site management

practices, the company continues to work towards its goal of zero workplace injuries.

Adept Civil has the same commitment to the environment, aiming to minimise pollution created during any works process and continually monitor its impacts on the environment through ongoing reports, audits and inspections. The company minimises the impact of its activities on the surrounding environment through adherence with its Environmental Management System, which complies with relevant legislation and the requirements of the xurrent edition of AS/ NZS ISO 14001.

This Environmental Management System allows for the setting of environmental objectives and targets at both the corporate workplace and project levels and provides the framework to ensure these objectives and targets are assessed and reviewed on an annual basis.

An Innovation Award Finalist, GeoKrete Geopolymer GeoKrete technology can easily be applied for storm and wastewater infrastructure rehabilitation, bonding to a multitude of surfaces.

AMS, in partnership with Melbourne Water, was a finalist for the Victorian Infrastructure Innovation Award for the employment of GeoKrete and it has been recognised as an official Reduced Carbon Footprint product.

Head to our website https://aquametro.com.au/geokrete/ to learn more about how we have employed GeoKrete into recent projects.

BEFORE AFTER The GeoKrete Geopolymer liner has been utilised throughout Victoria since 2019 in both degraded and failing sewer and stormwater pipelines and structures to significantly increase the service’s life span. The GeoKrete liner has a minimum 28-day compressive strength of 50MPa and the required thickness can be varied based on design requirements.

The lining process can be installed via accessing existing manholes without any demolition needed. GeoKrete technology is suitable for pipes and structures above 900mm in diameter and is not restricted by the structures shape. It can be applied to various existing host structure materials such as concrete, brick or steel.

Geokrete has a very short curing period, meaning rainfall events have minimum impact to the project progress with all equipment easily removed and repositioned as required. Aqua Metro Services has had great success when employing this technology to projects in Victoria.

The Vermeer D40x55DR S3l drill.

All systems go with Vermeer HDDs All Systems Contractors is a specialist rail signalling construction company based in Braeside, Victoria, and its Vermeer fleet of horizontal directional drills (HDDs) is well-equipped to take on any job, big or small, right across the state.

A

ll Systems Contractors has been operating under father and son team Steve and Russell Shore for nearly 20 years, and it has a full fleet of earthmoving and digging equipment – from trenching machines through to excavators and skid steers. Three years ago, Steve and Russell decided to branch out and invest in their own drilling equipment, rather than using subcontractors.

“Our subcontractors had generally been using Vermeer equipment, so we were familiar with it and how it ran. The machines always looked solid and equipped to handle anything, so we went for it and bought a turn-key D20x22 S3 drill package from them, and haven’t looked back,” says Steve.

Last year, the company also purchased an RTX1250 ride-on trencher, then in September it added a larger D40x55DR S3 Rock Drill to its fleet.

“We’ve had a lot of requests to quote for bigger jobs that needed a bigger drill, so we decided to invest in a D40x55DR S3 drill as well.

“The smaller drill goes out on our regional jobs, where we are usually doing level crossing upgrades and need to bore under the railway and road, around the signals and boom gates.

It’s easier to get around and those jobs don’t require as much drilling.

40 TRENCHLESS AUSTRALASIA JUNE 2021

“The larger drill we use with our metro crew, mainly on the Victorian Government’s Level Crossing Removal Project. The metro jobs are usually bigger jobs that need a bigger drill,” says Steve.

For Steve, Russell and the All Systems Contractors team, the one thing that stands out about the Vermeer equipment is its usability.

“I don’t get out to site to use the machines as much as I’d like to, but I can see how easy they are to use. The technology and computer systems make them easier to operate and

know where you’re digging and how deep.

“They are really user friendly, and best of all safe. There is a lot of scrutiny around the work we do, and we have to be precise with our holes and drilling, so they suit our jobs perfectly,” says Steve.

“It’s no secret Vermeer is one of the best when it comes to HDD and drilling equipment. We’ve bought three packages from Vermeer Australia in three years, and we’re not going anywhere else.”

Increasing the HDD radius Radius HDD delivers unbeatable, high-quality rock tools to horizontal directional drilling professionals worldwide, thanks to a comprehensive product list and extensive industry expertise. The company’s commitment extends further than just the end product, with a key mantra to further the industry through education and knowledge-sharing.

A

lthough headquartered in the US, Radius HDD is continuing to make inroads in Australia and New Zealand as the word spreads about the quality and efficiency of the tools it offers. The company works directly with HDD contractors to address any deficiencies in their current toolbox and provide the necessary equipment to allow for project success.

Key tools Radius HDD offers a wide variety of equipment for the market, including simple and effective tools as well as more complex and advanced pilot tools. The company’s Radius Rock Bit is one of its most versatile and popular products, delivering greater on-grade steering control in soft conditions while letting the user navigate loose rock and solid rock terrain.

The Rock Bit comes in a range of sizes and variations and is compatible with both Vermeer and Ditch Witch machinery. Similarly, the Radius Cobble Bit is designed to be a very productive tool option for hard packed soil, 42 TRENCHLESS AUSTRALASIA JUNE 2021

gravel and cobble conditions.

Gravel, loose rock and cobble have always been a challenge to navigate with offset bits and flat blades, but the centre “scoop” design of this tool effectively removes smaller loose debris while concentrating the carbide cutting surface on larger cobbles or rock. The Cobble Bit is machined from heat treated alloy, has carbide buttons and is hard facing, making it tough enough to withstand harsh onsite environments.

Another Radius HDD staple tool is the Single Roller Cone Bit. Also compatible with a variety of Vermeer and Ditch Witch machines, the tool’s proprietary design delivers better steering than any competitive bit, while a carbide-covered steering plate and additional carbide on the face delivers better grinding capabilities for loose rock jobs.

Radius HDD also offers its Steerable PDC Bit. Made to move rock, the Radius design is field proven to cut and steer through low to medium grade solid rock and is a must-have for any HDD professional. All Radius tools have been designed with input from drillers in the field, resulting in

strong, durable equipment that has been tested by in real conditions and proven to work.

More than just hardware Radius HDD is committed to continuing to expand the knowledge of not only its team, but the wider HDD and trenchless industry.

TRACTO breaks harder ground with JLM Underground Solutions

TRACTO-TECHNIK Australia Sales Manager Daniel Toms (right) with JLM Underground Solutions Managing Director John Mundy.

TRACTO-TECHNIK’s unique range of trenchless pipeline construction products are known for their ability to make difficult tasks a much simpler proposition through their technological superiority and ease of use. The GRUNDODRILL 18ACS is no exception, with impressive capabilities to drill through all tough geological conditions, including firm rock formations.

H

eadquartered in Germany with a presence the world over, TRACTOTECHNIK produces machines and accessories for the underground installation and renewal of pipelines with a focus on innovation and efficiency.

Among its wide range of products is the GRUNDODRILL 18ACS – a horizontal directional drilling (HDD) rock drilling rig suitable for any project, regardless of terrain.

The machine is capable of a stepless adjustment of torque and speed allowing for maximum power and productivity on the job and the best possible adaptation to all soil conditions.

Equipped with rods for every purpose, the GRUNDODRILL’s Elicon 95 twin-tube rods and the rock-breaker with roller bits or PDC are perfect for tough, specialised operations, while directional bores beneath roads, railway tracks and buildings are all standard applications for

44 TRENCHLESS AUSTRALASIA JUNE 2021

this machine.

The Elicon rods have an inner tube bedded inside the outer tube by means of wear elements, and the inner tubes are quickly and firmly connected using plug-and-twisted connectors.

This special design makes maximum fluid volumes possible even with long drilling bores.

When detection of the bore is especially demanding, the GRUNDODRILL applies cable-guided drilling, allowing the operator to achieve project success when drilling underneath water bodies or when interferences occur. The machine uses two multi-function joysticks for all functions in drilling and driving mode, and different operating modes can be freely selected by the machine operator to suit any need.

In the field JLM Underground Solutions is a civil contractor headquartered in Victoria

specialising in rock drilling. The company has been in the trade for more than a decade and has steadily progressed to working on major utility installation projects.

Earlier this year when searching for a new piece of equipment with the capability to satisfy the increasing demands of today’s infrastructure projects, JLM Director John Mundy was turned onto TRACTOTECHNIK and the GRUNDODRILL 18ACS. “I was looking for a very reliable drill with more power for the footprint and to open larger diameter holes, because that’s what these sites require now – clients are often looking for more conduits installed in a single hole ,” says Mr Mundy.

“I heard about the GRUNDODRILL through word of mouth from other drillers who use them. We needed something with a

HDD

larger mud pump and power to suit and the GRUNDODRILL 18ACS fits that bill.”

A new purchase, Mr Mundy says his experience in the weeks since have been all positive.

“It’s been fantastic. The job that we’ve been using it on has contained some really hard mud stone and the GRUNDODRILL 18 ACS has been performing very well,” he says.

“It’s got a more powerful engine and the machines pullback power and rotational torque are very impressive. JLM is already very experienced in rock drilling, but this machine has allowed us to have the comfort of opening up a larger and longer hole than we previously had before.

“And TRACTO-TECHNIK Australia’s customer service has been excellent. The communication and the willingness to provide information and product advice has been second-to-none.”

With its first GRUNDODRILL now at work, Mr Mundy says this new equipment will continue to take JLM from strength to strength.

“I think the future for us is excellent and we hope to continue purchasing more, and larger, drills from TRACTO-TECHNIK as time goes on.”

Customised to suit all needs Australian Custom Pipes is an independent, Australian-owned polyethylene pipe manufacturer with more than 20 years of experience in the market. The company’s quality PE pipes have supported countless projects around the country and have continually proven to be compatible with trenchless methods of construction.

A

ustralian Custom Pipes (ACP) is committed to providing the highest quality PE pipe available, complemented by the best and most dedicated customer service and support. The company can provide bore pipe in white or

orange, in large coils and in lengths up to 20 m, or customised to suit your project, helping clients save money by getting more pipe laid each day and minimising waste from off cuts.

In addition to a reliable product, ACP always delivers as promised. The company knows how important it is for deliveries to be on time, as nobody wants to keep their crew on standby waiting around for a truck to arrive. ACP keeps its delivery date promises and works closely with clients to coordinate the best outcomes.

A natural trenchless fit With the rapid take up of solar as the most cost-effective build and generation of power, ACP have been involved in the supply of conduit to major projects in regional Victoria, western NSW and southeast Queensland. During this initial avalanche of solar installations, a major challenge arose in running conduits, as power was coming in from all directions from numerous arrays of panels over a widely spread area.

In order to overcome these issues, the specification moved to trenchless technology, specifically horizontal directional drilling (HDD), to allow conduits to come in and transverse many obstacles on their way to sub stations. ACP was able to provide a 315 mm PE orange conduit in place, capable of handling the heavy-duty cables involved, meeting the UV stability required and with little disruption to the major works underway.

ACP has developed all its PE pipes to meet AS2053 for conduit applications. This allows clients project works to move away from the older methods (gluing PVC\welding steel pipes) and towards the use of HDPE coils using trenchless options like HDD or pipe bursting.

This has been of great benefit when clients are looking to install pipes over great distances and has been particularly beneficial and effective on major projects like airports, subdivisions, highway construction, infrastructure builds involving water, sewer, power, communications, fire, gas, river

ACP can provide bore pipe in white or orange. in large coils and in lengths up to 20 m.

crossings and more.

Ticking all the boxes ACP is recognised in the market for costcompetitive quality products and service.

The company is dedicated to employing ever-increasing modern machinery and rigid inspections procedures throughout its manufacturing processes to ensure a high standard of accuracy with pipes, fittings and fabrications.

ACP also prides itself on its quick turnaround times, both in customer service and manufacturing, and its products are approved to supply water authorities from Adelaide to South East Qld. These pipes support projects in regional and remote areas, with PE pipes up to 315 mm in the colour, stripe, jacket or even internal jacket to meet all specifications.

Even if the required pipe is uncommon or not in stock, ACP is capable of manufacturing and delivering the necessary products in a short timeframe.

What the data says about the cause of defects in wastewater networks VAPAR digs into the data on its pipe assessment platform which processes and organises inspection footage from inside wastewater pipes.

Debris in stormwater drains is the most common service defect, and often collects in maintenance shafts.

Background Pipe inspections and condition assessments are an important part of the operations of water utilities and city councils who manage wastewater networks. The collection and analysis of this information has traditionally been managed by each organisation individually, making generalised insights difficult to come by.

VAPAR has developed a pipe assessment platform where pipe asset owners and CCTV companies can process and organise video footage of the inside of wastewater pipes and either manually or automatically detect and classify the defects inside these pipes. The footage and information that has been collected as part of this process from various locations and organisations has yielded some interesting insights which are summarised within this article, with the full version accessible online.

Stormwater vs. sewer pipes Diameters: in urban areas, properties need to be connected to the sewers and the pipes they join will generally start at 150 mm in diameter - a relatively small diameter. Conversely, stormwater pipes are installed where overland flow depths in kerb profiles are insufficient. Stormwater pipes need to carry a larger capacity from the upstream point which generally start at 300 mm in diameter.

Material: due to the sheer number of sewer pipes that need to be installed and mix of greywater, blackwater and trade waste, price and accessibility of materials plays a large factor, meaning many more sewer pipes will be made of PVC or vitrified clay than stormwater pipes. Since stormwater pipes are typically of larger diameter (and therefore demand greater reinforcement), more expensive materials such as concrete will be used for installation more frequently.

52 TRENCHLESS AUSTRALASIA JUNE 2021

Environmental factors: sewer pipes will generally contain less debris (street litter, leaves, branches) than their stormwater counterparts. However, because sewer pipes are typically smaller in diameter, always flowing, and have more lateral connection/junction points, there’s a greater comparative risk of blockage. Sewer pipes are also more susceptible to pipe material degradation due to constant flows and chemical byproducts of wastewater e.g. hydrogen sulphide causing pipe corrosion.

Stormwater lengths are slightly longer on average than their sewer counterparts since they have fewer connection points and changes in direction, thus needing less maintenance pits on average.

Datasets for analysis The footage used for analysis had been uploaded to VAPAR’s cloud platform for automated analysis during late 2020, and was sourced from clients located in Australia, New Zealand and the UK. Structural defects in sewer pipes Concrete: surface damage is the most common structural defect that was found in concrete sewer pipes, typically caused by flow turbulence and the chemical composition of the sewer matter. Once concrete aggregate has been exposed from initial surface damage, corrosion accelerates with concrete cover reducing, steel reinforcements become exposed to air and moisture, causing them to corrode. Small cracks were the second highest frequency defects found. Due to reinforcement, large cracks are less prevalent in concrete - once the cracks become large they often become breaks.

Vitrified clay (VC): unlike concrete, vitrified clay pipes are not reinforced, so longitudinal, circumferential and multiple cracking are very

CCTV

common defects for this material type. This was the case for the data analysed, with the majority of the cracking characterised as longitudinal.

Almost 80 per cent of the defects reported in VC were cracks. The second most common defects were breaks, likely due to cracking.

Flexible Plastics: Due to the “flexible” nature of flexible plastics, it’s no surprise that small magnitude deformation was the highest frequency defect found for this material type.

Different characterisations of cracking were also observed.

Structural defects in stormwater pipes Reinforced concrete: A surprising amount of circumferential cracking, spalling and minor infiltration can be introduced through lifting holes (also referred to as a lifting eye, found at 12 o’clock inside the pipe to aid handling and installation).

Similarly to concrete in sewers, concrete stormwater pipes are also subject to cracking; however, surface damage was less common, since stormwater is typically less gaseous and corrosive than sewage.

PVC: small, medium and large magnitude deformation defects were more than 80 per cent of the defects found in stormwater PVC pipes.

Most PVC pipes will deform over their design life. The degree of deformation, and the time span over which this deformation is observed are the important factors for asset owners to understand when making maintenance decisions for these pipes.

Service defects in sewer pipes Displaced joints: minor radial displacements were the most common defect type, occurring 2.5x as often as longitudinal displacements (also known as “open joints”). The prevalence of displaced joints within pipe infrastructure is most common in vitrified clay pipes, particularly older designs without rubber rings in joints.

Roots: roots were the second most observed

category. Roots often make their way into the pipes through joints so it’s interesting to note that displaced joints are the most common defect type, and there may be some cause and effect. A study undertaken by the University of Melbourne1 outlined the most common factors causing greater frequency of root invasions, those being tree proximity, tree maturity, tree type, soil type, and temperature/evaporation rates. The study found that “blockages occurred most frequently when temperatures and evaporation were at their lowest, i.e., August to October”.

Service defects in stormwater pipes Debris: small amounts of debris (up to 20 per cent) in stormwater pipes were the most common defect found. Apart from the reduction in cross sectional area, small amounts of debris and deposits start to become an issue when the presence of that debris/deposit increases the risk of additional debris accumulation over time.

An additional challenge is that debris tends to collect in the maintenance shafts and entry points of stormwater drains, making a total blockage more likely in these areas.

Infiltration: infiltration/inflow in underground pipes is another common observation in the stormwater CCTV sample dataset, and in stormwater CCTV inspection footage in general. Groundwater ingress and other water source interactions with stormwater pipes are responsible for this defect. Infiltration/ inflow is not as consequential in stormwater pipes, though something to note during CCTV inspections as they may indicate poor joint tightness or other defects that are less visible.

Defect prevention Structural defects: structural defects often stem from initially minor imperfections that degrade over time. The rate of degradation is important to note in order to undertake the right remedial actions at the right time to optimise expenditure. Additionally, there are a number of details, that if addressed at the time of installation, can extend the structural lifetime of a pipe. Examples include, correct bedding material and compaction, sufficient cover, and suitable hydraulic grading of the pipe to specification.

Service defects: as for structural defects, displaced joints and root intrusion defects can be minimised with the right installation and using spigot and socket (or similar) pipe joints with sealing rings. The application of herbicidal foam in sewers is one of the leading solutions for reducing regrowth of roots that enter sewer pipes. This tends to perform better rather than root cutting, as roots tend to grow thicker and faster when cut. In stormwater, ideally debris would be collected in gross pollutant traps, or litter traps, at key points in the network, and pipes should be laid with sufficient fall to allow debris to flow more smoothly through the network.

Summary There is a wide range of factors that contribute to the structural and service defects that impact wastewater networks. Understanding the trends in various materials can assist when making maintenance decisions to extend the lifetime of a pipe asset and to optimise maintenance expenditure.

QuickLock remains key to pipe repair Sewer Equipment Company (Aust), or SECA as it’s more commonly known, is Australia’s leading supplier of sewer and drain cleaning, testing, inspection and rehabilitation equipment. For structural, trenchless pipe repair, the company offers the Quick-Lock solution.

T

he Quick-Lock system has revolutionised sewer rehabilitation through its wide range of applications and strong reliability. Using heavy-gauge 316 stainless steel with infiltration abatement with an EPDM rubber gasket, the Quick-Lock system seals and stabilises damage completely by mechanical means, removing the need for chemicals and making it suitable for all pipe materials.

The patented locking system ensures that the sleeve stays permanently in position and, after rehabilitation, the sleeve has its own static capability and absorbs the natural tectonic movements of the pipe.

The system can be used for standalone permanent point repair, or for prelining stabilisation works including high groundwater infiltration. Quick-Lock sleeves restore a pipe’s structural integrity and seal out groundwater, and they are carefully designed to minimise diameter loss and outlast any other rehab.

For larger pipes, SECA offers the QuickLock BIG sleeve, which permanently seals leaking pipe joints, radial cracks, and longitudinal cracks in large pipes and manholes of DN800 and larger. The BIG sleeves are 20 cm wide, and the system is made from V4A stainless steel of grade 1.4404 (AISI 316L) and an EPDM 54 TRENCHLESS AUSTRALASIA JUNE 2021

The Quick-Lock liner end cuff is used to connect pipe liners to pipes and structures.

These materials are permanently resistant in municipal wastewater systems, while their suitability must be ascertained for use in industrial or polluted wastewater.

Out in the field SureSearch has more than 20 years of operating experience as a company, providing all aspects of utility investigative works, including location, non-destructive excavation, utility survey, mapping and clash detection, CCTV inspections, drain cleaning and pipe rehabilitation offers.

SureSearch Sales and Development Manager Calyn Wilkinson says the company was relatively new to the pipe rehabilitation sector and felt using the Quick-Lock system was a good way of entering the market.

“SureSearch has used the Quick-Lock system for both sewer and storm water rehabilitation,” he says.

“It has been used for sealing joints, holes and also infiltration through cracks. Due to the fast installation time and no curing of material, it has a great advantage over the cured-in-place pipe (CIPP) method.

“More installations can be achieved in a shift and if traffic control is required then this limits the amount of money spent on traffic control shifts.”

Quick-Lock end caps strengthen a CIPP liner at its most vulnerable points—the ends. This mechanical solution prevents liner and host pipe infiltration or exfiltration for the lifetime of a close fit liner.

It is particularly most effective on EX, spiral, and UV cured liners, and it is stronger and easier to install than other end caps, making them highly beneficial on any long-term watertight lining project.

Quick-Lock systems can be purchased from SECA’s warehouses or from SECA’s nationwide sales representatives.

Aussie Trenchless is now launching what it is calling the ‘Rehab Combo’ PST – this nimble segmental lining system offers benefits such as faster installation times, transparency to grouting quality and suitability for live loads securing the access chamber substrates.

The PST traversable culvert lining system has been adapted to vertical access chamber lining and sealing, removing the need to remove the access ring and cover as the PST panels easily fit through a standard 600 mm access lid. The panels then bolt together in the chamber to form a ring, securely positioned, then the annulus gap is grouted.

There is no flow interruption to the network and visually the grout quality is apparent. Additionally, the size and depth of the access chambers is no issue as the panels are built up progressively and can be grouted as the liner walls are installed.

More to offer Aussie Trenchless continues to supply the SRP Spiral Lining System to the local and international markets for the rehabilitation of DN150 to DN1200 sewer and stormwater pipes. The close-fitting structural spiral ribbed

PVC trenchless pipe lining system is used in circular sewer and stormwater gravity mains and is possible to install under live flow conditions.

For installation, the special winding machine is positioned into an access chamber or pit and then helically winds the SRP-EXP ribbed strip to produce a pipe within the existing pipeline. The winding machine is initially set to a smaller diameter than the host pipe and as 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. Upon reaching 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 existing damaged pipe without the need for excavation.

Aussie Trenchless’ PST is now making its debut in the refurbishment of access chambers.

Aussie Trenchless is continuing to develop new products and methods and the company says these will become available as market demands increase.

With Infrastop in place, Interflow’s Titeflow process then installs a new tight fit HDPE pipe into the host pipe. This snug-fitting technology uses H112, an internationally recognised, high quality, high strength PE100 compliant resin that is specifically designed for pipe applications.

The Titeflow pipe is towed under tension through a static die, reducing its diameter and allowing it to pass through the host pipe.

Once it is in place, the pulling load can be released. The liner pipe increases in diameter,

ilmot Pipelining conducts the rehabilitation of pipelines of all sizes and shapes, possessing the capability to install long distance liners in a single day in order to both upgrade an asset owner’s infrastructure, and have the asset back up and running with minimal disturbance to the public.

The company transforms ageing pipelines and infrastructure using its extensive experience and expertise, repairing failing pipelines and assets using the latest trenchless pipe relining technologies. Wilmot provides a variety of different rehabilitation ranges to its clients and the company prides itself on a pipeline rehabilitation solution for any situation.

Many of these infrastructure upgrades are carried out on municipal assets like water, energy provision, wastewater, industrial facilities and refineries.

Emergency asset rehabilitation In the first half of 2021, Wilmot Pipelining has provided pipeline renewal assistance to several councils and authorities in NSW to help with the replacement and rehabilitation of damaged infrastructure as a result of recent flooding in the state.

Wilmot’s relining and civil works teams responded quickly to ensure council assets were made safe and functional with reactive support to the flood effected areas. The company’s lining crew reacted to assist on two separate sites to assist councils with sewer surcharge and flooding after an extremely rare rain event that produced intense and dangerous flooding in the area.

The team then shifted to successfully excavate a large sink hole to repair a DN1800 culvert damaged in the floods. The site was made safe quickly and safely by Wilmot personnel which helped avoid the very real and dangerous possibility of the roadway dropping into the flood affected sink hole.

Not content to rest on its laurels, Wilmot is now installing the largest cured-in-place (CIP) UV light cured liner to date in Australia at the same site where the sink hole was formed. The

delivery team is busy engineering the liners and custom manufacturing equipment in-house to complete the installation safely and efficiently.

The Wilmot team is currently delivering a variety of other large trenchless projects throughout the state, with both UV cured CIP lining and large diameter slip lining methods being adopted and re-engineered in many cases

by Wilmot’s engineering team to suit the site constraints and requirements.

Wilmot has also taken quality assurance to the next level through the simulation of liner installations and ground stabilisation techniques that demonstrates the team’s commitment to this area.

With a strong background in pipeline construction and hydraulic services, the team at Wilmot has a strong understanding of the way pipelines are constructed. This understanding, combined with the trenchless approach to rehabilitation, makes Wilmot the complete pipeline and infrastructure rehabilitation company.

Treating sewer lines with Vaporooter Drainchem is a leading supplier of drain and pipe maintenance and testing equipment for the drain construction, testing, cleaning and repair industry. The company offers the Vaporooter foaming sewer root inhibitor to treat sewer lines, which decreases maintenance costs and extends the life of the asset.

V

aporooter is the original and most successful sewer root herbicide, is currently in use by various authorities in Victoria, New South Wales, Queensland and South Australia. It is designed to kill existing roots and retard regrowth for up to three years.

Vaporooter is the most cost-effective technology for maintaining sewer systems against tree root intrusion without harming trees, plant life or pipes.

When used according to recommended operation guidelines it will not harm wastewater treatment plants. The product is a combination of herbicides, placed in sewer lines as foam for the purpose of eliminating

roots and preventing further destruction of sewer pipes caused by live tree root infestation.

Only roots within the pipe, in the pipe wall and a short distance outside the pipe are affected, while trees and shrubs immediately above the pipe are not harmed. Foam is used to carry the main ingredients, metham sodium (herbicide), and dichlobenil (growth inhibiting agent) to the root mass because a root mass usually enters at the top and sides of a pipe, forming a vale or tale type structure.

This application process ensures the pipe is full of foam so the roots will come into good contact with the Vaporooter ingredients. A jetting truck is used to clean the roots to achieve the best root surface contact with Vaporooter.

The foam generating equipment is crucial for achieving the best results from the herbicidal foam and applying Vaporooter through certified foam maker and jetting equipment allows for total control of the quality of the foam. This proven application method eliminates the need to cut roots before the application of Vaporooter and during the guarantee period.

The very act of cutting roots, while necessary to clear blockages, promotes thicker and more vigorous root regrowth – for this reason root cutting should be a last resort. If root growth in the pipe is very high, constricting the flow of the foam, root cutting should be undertaken a minimum of six weeks prior to foam treatment to allow the roots to start to grow.

After a Vaporooter treatment, the roots die, become septic and soft, and then drop off into the flow. This allows ground pressure to close the cracks created by expanded roots and help reduce infiltration and exfiltration. The end result is a healthier environment, a longer lasting sewer asset, reduced maintenance and operating costs and a more

efficient treatment operation.

Proven method Years of field testing has shown the manufacturers of Vaporooter that the combination of the three ingredients, metham sodium, dichlobenil and sanafoam are the formula for success in root control.

Substitution of any one of the ingredients

greatly reduces the overall efficiency of the product, as such, Vaporooter has become recognised as the most effective form of root control available today.

Once lines are treated with Vaporooter, they should left undisturbed for a period of

no less than six months, so that the biological disintegration of the root masses can take place. This process will kill roots immediately, but they rot and drop off over a period of time, so the desired results will come over a period of time.

Smart Lock bridges gap in NZ The Smart Lock is an innovative and simple solution for the sealing of cracked pipes, root infiltration, lateral connections and erosion. The technology was recently used in a vital pipe repair project in Wellington, New Zealand.

H

ydroTech Group was recently approached by Wellington Water in Wellington, New Zealand to secure a 450 mm EW stormwater pipe running under a major carriage way and critical water and telecommunications infrastructure in the city’s central business district.

The pipe was installed more than 100 years ago and was failing in a number of sections, causing “tomos” or voids to form underneath the carriage way. This significantly increased the risk of a potential road collapse and flooding upstream, making rehabilitation a necessity.

Smart Lock sleeves were used to create bridges within the EW pipe and directly underneath the critical infrastructure, which reduced the risk of further pipe collapses or failures and gave valuable time for a permanent solution to be found. Even with major joint displacements and pipe failures along the asset, Smart Lock sleeves were installed safely in critical locations.

In total, 22 Smart Locks were used for this project, and the risk of pipe failure and creation of further tomos or voids has been significantly reduced. Wellington Water is now installing a new 750 mm pipe by traditional methods as a means of asset replacement.

But, with efforts underway from the Australian Government to keep the economy afloat, there now exists opportunities for businesses to take advantage of unique incentives that exist in market conditions rarely, if ever, seen before.

KOR is a national business supporting contractors through the provision of industrial vacuum trucks, combination sewer and drain cleaning trucks for the waste, environmental, mining, civil and industrial sectors.

the government’s response to COVID-19, it provides a rare and unique opportunity on eligible assets purchased between now and 30 June 2022. The full cost of the asset will be deducted from company profits,” says Mr Roberts.

“For example, if you acquire a new or used unit for $660,000 you will receive 25 per cent back in short term tax relief that equals to $165,000 in boosted cash flow when you lodge your income tax return.”

To complement the Temporary Full Expenses, there are additional and fundamental reasons why KOR believes there is no better opportunity to capitalise on this once in a lifetime government incentive where you can upgrade or grow your fleet before it’s too late.

The government’s spending response to COVID-19 has injected significant supply into

infrastructure improvement and new project sectors, while the fast tracking of major projects has resulted in an oversupply of work.

“We believe if you have the equipment and operators there is an abundance of opportunities out there,” says Mr Roberts.

“The current cost of capital for equipment finance has never been lower when we compare the rates from 2017 rates were roughly between 6-9 per cent whereas in 2021 rates are at 2-4 per cent. We are seeing extended residual or balloon payments for 3-5 years which can significantly reduce monthly payments and therefore can increase overall cash flow.”

COMPANY NEWS

The future of microtunnelling As an increasing number of pipeline installations go trenchless, the already-impressive capabilities of equipment on the market continues to improve. Edge Underground is a company leading this consistent evolution of trenchless technology, and it remains committed to breaking new barriers in the industry.

The AXIS laser guided boring system is a leading machine on the market.

T

he microtunnelling industry has grown exponentially over the past decade, with advances in equipment and practices making it the ideal choice for pipeline installations where a high level of accuracy and minimal disturbance to the surrounding environment is required. As a relatively new construction technique, it has seen rapid development and growth over the years, and the next ten years are expected to see it evolve even more.

Since it was first used more than 50 years ago, microtunnelling has gone from achieving successful installations some of the time, to some machines being able to provide a consistently successful installation with an accuracy of ±10 mm. A lot of this evolution in capabilities has taken place from the 2000s and the technique has since become 72 TRENCHLESS AUSTRALASIA JUNE 2021

an increasingly popular choice for trenchless pipeline installations in Australia and overseas.

Global microtunnelling pioneer and Edge Underground Managing Director Stuart Harrison has been at the forefront of the industry’s evolution, having developed the AXIS laser guided boring system in the early 2000s after seeing a gap in the market for a machine that combined pinpoint accuracy with a high level of productivity and efficiency.

The AXIS is now a leading piece of equipment on the market. The most accurate machine, it is designed with a host of unique features such as the ability to perform pilot lines and retract to reduce problems occurring from unexpected ground conditions, and safety elements including pressure gages and a Falling Object Protective System (FOPS) safety enclosure.

“The growth of the industry and our capabilities over the past ten or so years has been significant, seeing us being able to take on projects that we never would’ve been able to previously,” says Mr Harrison.

“But there is still growth happening and to be had, and I think the next 10 years will be huge, seeing the industry expand even more and further increasing the scope of what we can do.”

What is driving growth and development?

Mr Harrison says this growth and development will not only be driven by equipment, but by work practices and project design, allowing contractors to find new solutions to problems and enabling them to put together a competitive package that

provides a true alternative to open cut.

“I encourage my team to be at the forefront of this evolution – looking at the design of a project and thinking outside the box to see if there’s anything that can be changed so that the entire project can be done using microtunnelling or other trenchless technologies,” he says.

“If we can do this, it would not only be more cost effective, but the time needed to complete jobs will be shorter. Then there are the flowon additional benefits such as less disruption to the community and businesses, as well as to the environment.”

Mr Harrison says driving this kind of industry development is only possible when there is a group of committed people who want to set benchmarks and actively search for ways to improve what they’re doing every day.

“At Edge Underground, we have a group of committed people that are not only trying to set a benchmark in the industry with the equipment that is currently available, we also are very much shaping the future of the industry by looking at ways to improve the equipment and how it’s used to make it more capable to handle not only just the various ground conditions that are out there, but do it more reliably and more consistently.

“The traditional ways of doing pipe installations are definitely reducing year-by-year, and maybe ten years from now a majority, if not all, pipeline installations will be done trenchless. That evolution will ultimately be driven by us as an industry, and us as individual companies, to keep pushing the boundaries of what we can achieve with our equipment and practices.”

Microtunnelling can now provide consistently successful installations with an accuracy of ±10 mm.

T

he Drain Group (TDG) provides comprehensive environmental and recycling services up and down Australia’s east coast. Included in its group of companies is Total Drain Cleaning (TDC) – a proudly Australian owned and operated company, specialising in providing innovative solutions to stormwater and sewer assets.

Combined with world-leading technologies, experienced team members, and long-term industry knowledge, TDC can deliver projects of any scale, from simple blocked pipes to servicing large networks of gross pollutant traps. TDC offers a 24/7 service ranging from programmed and periodical maintenance contract services to emergency and casual call-out response services.

With more than 250 employees and more than 110 vehicles in its fleet, TDC is well equipped to supply both large and small projects, while its innovative mapping, GPS 74 TRENCHLESS AUSTRALASIA JUNE 2021

and specialised online software provides unparalleled transparency to its customers.

New TDG companies In 2021, TDG announced Bartlett’s Environmental and RSP Environmental would be joining its stable of companies.

RSP Environmental Services specialises in sewer and stormwater asset maintenance, established over the past three decades through its advanced solutions and strong customer focus. Located in central Victoria, RSP’s drain cleaning and CCTV services are best placed both demographically and strategically and it has built an excellent reputation across regional Victoria.

Bartlett’s Environmental specialises in solid and liquid waste management across the sewer and stormwater market with extensive capabilities in the areas of waste processing and recycling. With a history also spanning more than 30 years, Bartlett’s Environmental has grown into one of the leading service providers

across Victoria.

These businesses share strong similarities to TDG, particularly with respect to the circular economy, minimising TDG’s environmental impact and its aim towards zero litter in the oceans. Similar to Mainstream Recycling (another constituent of TDG), Bartlett’s also has a strong focus on recycling in the management of its waste, operating its own recycling facility in Geelong.

All businesses started off as family owned and operated companies that have grown through the drive and success of Founders Nick Messina (TDG), Hugh Richard (RSP Environmental) and Darren Bartlett (Bartlett’s Environmental).

TDG is now comprised of RSP Environmental, Bartlett’s Environmental, Total Drain Cleaning, Environmental Services Group, Utility Track and Mainstream Recycling, and this acquisition represents the next phase of growth for this group of companies.
