Primus Line® advances in Australia

It goes without saying that infrastructure for water supply will always be relevant.  

However, much of this infrastructure is ageing, with leaking or even shut down pipes underlining the necessity for renovation.  

Usually, these pipes are renewed or revitalised by dig-and-replace, but over the past few years, utilities worldwide are looking more and more for trenchless solutions.  

The advantages are clear: shorter installation times, fewer impacts on the environment and reduced costs.  

Primus Line® – engineered and manufactured in Germany – is one of these solutions, consisting of a flexible, aramid-reinforced liner and special developed end fittings.  

Since Sydney Water undertook its first Primus Line project four years ago, nearly a dozen have followed, along with the projects for other utilities, councils and mining companies throughout Australia.  

These include Urban Utilities, Hunter Water, Unity Water and Shoalhaven City Council, to name just a few.  

Primus Line technology is currently the sole solution for the rehabilitation of pressure pipelines on Sydney Water’s list of products deemed to comply with pipeline rehabilitation.  

In cases of water spilling from damaged drinking water pipelines or sewage pressure lines in hard to access areas, such as beneath a creek, rapid response is essential.  

This is why some Australian pipeline operators already have Primus Line material on stock to present fast remedy in emergency cases, with Primus Line now found in even the most remote corners of Australia.  

In Cape Lambert, Western Australia, more than 1.5 km of drinking water pipelines have been rehabilitated using the product for Rio Tinto at a site of cultural heritage sensitivity.  

Other customers from the private sector, including Melbourne Airport, have already profited from the German trenchless renewal system, but Primus Line is used for more than just the rehabilitation of potable water mains – the range of completed projects extends to sewage pressure pipes, recycled water or raw water mains as well.  

Moreover, the Primus Line has been used on projects deemed nearly impossible. Examples include a 3-in-1 solution for Hunter Water (three Primus Liners DN 450 installed in a DN 900 pipe) and a vertical pipeline of more than 100 m for Sydney Water.  

To plan and calculate the projects, Primus Line relies on its in-house engineering team that gets to work immediately from project start, ensuring the Primus Line technology is the right product to carry out the job quickly and efficiently.

Interflow introduces new water main renewal system

By integrating these products into one synergistic process, Interflow said it is providing its customers and the community with an ‘all-in-one’ package for renewing ageing water main pipeline infrastructure. 

  

Traditional shutdowns using network valves are disruptive, impacting hundreds of customers at any one time.  

The Infrastop component within the RediFlow system can greatly reduce the number of impacted homes by isolating only those pipeline sections specific to the works being carried out.  

Interflow’s Titeflow process then installs a new tight fit HDPE pipe into the host pipe, restoring its structural integrity. 

Interflow Manager – Emerging Markets Will Zillmann helped develop the RediFlow system and explained how it can be leveraged to streamline processes in the field. 

Interflow Manager – Emerging Markets Will Zillmann.

“The RediFlow system is specifically designed for optimum construction efficiency,” he said. 

“It provides asset owners with a robust solution to suit the conditions of the host pipe and provides a range of environmental and social benefits for our customers and their communities. 

“The solution goes beyond the performance boundaries.  

It improves installation speed, reduces community impacts, and enhances the environmental sustainability of the works being conducted.” 

The implementation of Interflow’s RediFlow system onsite has already begun, with several successful installs to date.

Melbourne Water targets century-old sewer

The Hawthorn Main Sewer transfers sewage from the city’s east to the Western Treatment Plant in Werribee and has been in service for more than a century.  

Now reaching the end of its service life, the brick sewer will be replaced with two glass reinforced plastic pipes, with the project team to construct a shaft on each side of the Yarra and tunnel underneath the river.  

Stage one of the upgrade was the now-completed relining of a 1.7 km stretch from Power Street in Hawthorn to Burnley Street in Richmond.  

Melbourne Water General Manager of Program Delivery Eamonn Kelly said it was crucial the asset continued to function properly.  

“It will provide the community with a world class, secure and reliable sewerage service for the next 100 years,” he said. 

“The Hawthorn Main Sewer has always been an integral part of Melbourne’s critical infrastructure and to this day is one of the principal sewers in Melbourne Water’s 400 km network.” 

The project is targeted for completion in early 2023.

Old drains, new solutions

New Plumbing Solutions (NPS) is a provider of plumbing maintenance and civil works for water and sewerage assets.  

Committed to investigating and investing in new, innovative technologies to solve old problems, NPS turned to Smart Lock Group for a solution when an asset was excessively impaired.  

Simple method, complex problem  

NPS Delivery Manager Damian Bradley said its client had a severely damaged drain next to a café in parkland gardens with significant trees and hard landscaping surrounding it, resulting in any rain event compromising the café and leaving the community unable to use the gardens.  

Upon NPS’ inspection, while large sections of the drains were in good condition, there were a number of damaged sections identified which were causing the flooding.  

To avoid the costly and disruptive “dig-and-repair” method of corrective works, NPS was able to propose a blended relining and Smart Lock solution.”  

Smart Lock is a simple method of repair, where drains undergo CCTV inspections to pinpoint the most damage impacted sections of a drain and pipe.  

The ‘no-dig’ patching solution allows for drains that are cracked, or those that allow root infiltration, to be repaired in a trenchless, non-disruptive manner.  

“The simple installation and efficient cure time of using Smart Lock means the job can be completed with minimum disruption,” said Mr Bradley.  

Project-specific solutions Smart Lock understands that one size does not fit all, which is why its team endeavour to always find a practical and suitable solution for varying project needs.  

“For NPS’ drain repair, our solution recommended for more than 20 Smart Locks to be installed and one section of pipe to be relined,” said Mr Bradley.  

“Given the issues were rectified only where there was specific damage, the solution provided a cost-effective outcome, and the trenchless technology solution utilised ensured there was no business interruption.”  

Mr Bradley said there are many measurable benefits of using Smart Lock systems compared to traditional repair methods, including that it is 35 per cent cheaper, it allows for 100 per cent of business continuity during works and the time onsite is reduced by 40 per cent.

Brisbane pipe receives $4m facelift

Works are nearing completion on the relining of a 2.2 km section of the pipeline under Ann St from Newstead to Fortitude Valley.

Urban Utilities Spokesperson Michelle Cull said the 130-year-old pipe was a key player in Brisbane’s water network, pumping water to homes and businesses in and around the CBD.

“Every day the city and surrounding inner suburbs use about 25 ML of water – that’s the equivalent of around 10 Olympic-sized swimming pools,” she said.

“This project will extend the operational life of the pipe by at least 50 years.”

The original pipe will be relined using the Primus Line to minimise disruption to traffic and the community by inserting a liner into the existing pipe, negating the need to dig up large sections of the road.

Works are expected to be finalised in February.

Wilmot expands rehabilitation offerings

Wilmot Pipelining conducts rehabilitations of pipelines of all sizes and shapes to upgrade asset owner’s infrastructure and keep it operational. By using trenchless technologies, Wilmot can transform ageing and failing infrastructure with minimal disturbance. 

The company says it provides many different pipeline rehabilitation methods to its clients and prides itself on finding a suitable solution for any and all situations. With a strong background in pipeline construction and hydraulic services, the Wilmot team says it has a “good understanding of the way pipelines are constructed”. 

With most of its infrastructure upgrades carried out on municipal assets such as water, energy providers, wastewater, industrial facilities and refineries, Wilmot says it is now offering clients the rehabilitation of pits and manholes using its UV curing method that can complete a restoration in a matter of hours. 

The company ensures that similar to its other trenchless offerings, its new liners are installed quickly and with no impact on the network while carrying out the renewal procedure. 

World first

Wilmot Managing Director Andrew Wilmot says manufacturer Brandenburger Germany has created one of the first pioneered CIP cured manhole liners, which the company is now proud to be installing for its Australian clients. By using the innovative system, manholes and pits are transformed back to fully operational with a 50-year warranty on the asset. 

“As a pioneer and one of the world’s leading manufacturers of UV CIPP, Brandenburger Liner has used its experience to develop an innovative method for manhole rehabilitation,” says Mr Wilmot.  

“The Brandenburger Manhole Liner BBS.8 reduces logistical effort for our customers at the job site and allows an efficient, as well as holistic rehabilitation of the sewer network including manholes and sewers.” 

Mr Wilmot says the UV manhole liner adapts to the shape of the manhole solely by air pressure, which prevents any time-consuming measurements of the manhole in the lead up to the rehabilitation. 

“The specially designed stretchable GFR laminate generates three important advantages,” says Mr Wilmot. 

“Beforehand, no measurements of the old manhole are necessary, only the size of the manhole opening and the size of the manhole itself are needed. Secondly, there is endless production – with the special production technology, Brandenburger is able to produce all manhole liners at a stretch for diameters between 800-1,000 mm.” 

The Brandenburger UV liner being used by Wilmot Pipelining on a recent project.

Mr Wilmot says the third advantage is rehabilitation can now occur from the bottom of the manhole up to the sewer pipe. 

“With a special installation procedure, it is also possible to rehabilitate the bottom of the manhole with the Brandenburger BBS.8 material.” 

The Wilmot main office and depot is located in Newcastle, New South Wales, although the company can service all areas of Australia, offering homeowners and municipal asset and infrastructure organisations rehabilitation services using trenchless methods. 

Additional offerings

Alongside its many relining offerings, including UV lining, hot cure lining, point lining and patching, lateral seal lining and manhole repairs, Wilmot also offers various other trenchless services. 

As a Hunter Water Accredited Hydraulic services provider, Wilmot can construct new sewer and water mains. The team says its knowledge and experience gained from working on large-scale projects for more than 20 years has provided the confidence to deliver projects on time and within budget. 

Wilmot says it also has a diverse range of robotic cutters, including down the branch cutters, HSL cutters, reticulation cutters and beast cutters for medium to large bore pipelines, adding it can open up newly relined junctions and connections or remove large concrete deposits from pipelines. 

Additionally, the company produces high quality CCTV reports and assessments for its clients with the industry standard report system ‘Wincan’ to provide condition assessment and pre-and post-relining reports. 

Wilmot says it provides a complete pipeline rehabilitation service to its clients by including pipeline cleaning and waste disposal in its offerings, and completes this service using many different sized high-pressure water jetting and non-destructive digging units. 

“The Wilmot team pride themselves on having a cost effect and most non-destructive solution for any situation,” the company says, adding that it is an Australian family-owned company based on traditional values. 

“We pride ourselves on service, stability and reliability in providing pipeline rehabilitation solutions to our customers.”

Ticking every box

The company has completed countless underground infrastructure projects throughout New Zealand, often using its own custom-made trenchless tools to ensure elite performance.

Pipeline and Civil attributes its success to both its outstanding project expertise as well as its strong company culture of collaboration and inclusiveness. The company places a significant emphasis on the values of safety, quality, honesty, care and success when delivering each project and takes great pride in delivering results for clients on time, on budget and with a low impact on the surrounding community.

Pipeline and Civils’ custom built telescopic conveyor can be used for backfilling trenches from the end where access is not possible to backfill from the side of the trench. This is particularly relevant in constrained urban areas where local authorities demand that traffic lanes remain open, reducing lateral safety zones and preventing equipment from accessing the side of the trench.

Although it can now claim expertise in many areas, Pipeline and Civil was originally founded on its ability to deliver high quality water infrastructure. The company has constructed some of New Zealand’s largest water mains and has the capability to undertake many different construction and rehabilitation works, including installing high-density polyethylene rising mains, pump stations and associated pipe works, water treatment plants and storage tanks.

Pipeline and Civil sees immense value in using trenchless technology due to its environmental, practical and cost benefits, with the company saying most of its projects now use at least one trenchless method.

Pipeline and Civil is an expert in slip lining, having installed pipe strings up to 400 m in length and 1,400 mm in diameter, while its horizontal directional drilling (HDD) knowledge is also top level and its in-house welding team ensures only the highest quality welds are performed on a project. Pipeline and Civil also boasts expertise in pipe bursting, pipe ramming, microtunnelling and structural lining – the result of many years of experience across its teams and its involvement in some of NZ’s largest and most complex trenchless projects.

Additionally, the company has strong relationships with subcontractors that are experts in these methodologies, ensuring clients have the sharpest minds in the business on hand for their works.

 The image above shows work in progress on a 7 km of 710 OD PE pressure wastewater pipe in northwest Auckland.

Custom linear winch

In addition to its project expertise, the company’s leading technical and engineering knowledge has allowed it to develop its own custom-made tools to use onsite. Recently, a project with Hastings District Council and Stantec provided the opportunity to use a custom hydraulic winch, designed and built by Pipeline and Civil.

The hydraulic linear winch was developed for the specific purpose of pulling polyethylene (PE) pipe through a host pipe and can be adjusted to suit different sized pipes. Capable of pipe pulls up to 400 m in length and applying up to 45 t of force to overcome internal friction, the winch has now been successfully tried and tested across five projects by Pipeline and Civil.

The works included the installation of 1,460 m of DN355 PE pipe that was relined, using the hydraulic winch, through the existing 375 concrete pipe, which was very deteriorated in places and had recently required several repairs. To properly rehabilitate the asset, relining had been chosen as the optimal solution.

Relining an existing host pipe greatly extends the life span of the pipe and in this case also allows it to withstand more pressure and more flow. The Pipeline and Civil team also shut down three pump stations and installed three new valve connections and two 90° bends over the 1.5 km stretch.

The upgrade will allow the sewage system to operate with more efficiency at full capacity and the overall project was completed in just under 10 weeks.

ASTT makes calculated steps towards carbon reduction

The purpose of the ASTT is to advance the science and practice of trenchless technology for the public benefit, while promoting education, training, study and research and practice for the public benefit and to publish the useful results of the same.

With this in mind, paralleled with the global goal of reducing carbon emissions, the ASTT formed a Special Interest Group (SIG) of leading industry professionals to create a solution that supports the mitigation of climate change impacts.

Primary purpose

Mott MacDonald Water Sector Lead New Zealand, and Carbon Calculator SIG member Thomas Haarhoff says the carbon calculator “aims to use carbon as a measure for efficiency, encouraging people to innovate and get better results around their carbon emissions”.

“As trenchless construction may not always be the low carbon option, the calculator will help our clients and organisations to make informed decisions about reducing their carbon footprint,” he says.

“The intention of the calculator is just to be a simple tool. For example, contractors can say they have 100 m of sewer to be relined, sliplined, etc., and can use the calculator to determine which of the options will have the lowest carbon output.”

With an impending global need to reduce carbon emissions, the calculator will play a vital role in helping the trenchless sector do its part by acting as a tool for ASTT members to promote trenchless technology usage, allowing informed decision making to occur between various construction methods and driving innovation on carbon reductions.

“The main thing is, people potentially underestimate the carbon impact of construction and the total carbon we emit every year,” says Mr Haarhoff.

“By focusing on the industry, we can make a great change towards carbon emissions and climate change.”

Calculated steps

The ASTT says its Carbon Calculator is not to be relied on to make commercial decisions nor is it a tool that will accurately define Capital Carbon Baselines, noting that there is no specific, quantified carbon goal that the calculator aims to reach. Rather, the tool will be used to promote best practices across the industry.

The three steps the calculator aims to take are:

  1. Reduction – reduce the carbon impact of infrastructure.
  2. Behaviours – improve the behaviours of designers, constructors and entire supply chains to reduce infrastructure carbon.
  3. Union – create a common way of working to calculate carbon reductions across the industry, setting the narrative.

Mr Haarhoff says the calculator will be used on individual projects and tested across various areas, with the onus on contractors and client organisations to use the tool and consider their own impacts.

Ongoing developments

Mr Haarhoff says the calculator is still in early stages, with the ASTT receiving its application approval in June.

At the end of June, four different suppliers had submitted tenders for the calculator’s development, with the winning bid yet to be announced.

During the early days of the Carbon Calculator’s development, the SIG plans to continue promoting the innovation through its usual channels such as the ASTT forums, which are currently taking place as virtual events due to COVID-19 restrictions.

There will also be sessions dedicated to carbon calculator at next year’s No Dig Down Under event, which is the largest conference and exhibition dedicated to trenchless technology in the southern hemisphere.

If you are interested in being involved, please contact event organiser Great Southern Press on +61 3 9248 5100 or email conferences@gs-press.com.au

AMS completes innovative reline

Melbourne Water determined a section of the Pascoe Vale Sewer had a predicted nominal remaining asset life of 1-5 years, therefore requiring rehabilitation to extend its working life.

To combat the challenging project on behalf of the utility, AMS used the Quadex Lining System®, featuring GeoKrete® geopolymer, that bonds to the host structure, leaving no annular space.

The technology – a precision proprietary application system, built to a spec for high level performance – can be installed as a fully structural standalone liner to further extend the life and structural performance of the asset.

AMS said with access to the sewer manholes located at busy intersections in Strathmore, works needed to take place at night and were conducted in confined spaces.

The contractor completed jet washing the existing pipe, patch repair, treatment of corroded reinforcement and the sewer lining with the GeoKrete® geopolymer.

Winching to a win for top supply services

Due to COVID-19, the Hire and Rental Industry Association Australia had to postpone its 2020 Company of the Year competition; however, Winch Hire Australia is set to return in 2021 as one of two finalists, nominated for its unmatched service offerings.

Winch Hire Australia offers a variety of specialised diesel and electric winches for the pulling of all different sized pipes and liners. Its hiring services are available across the country with rentals also available for projects in nearby countries such as Papua New Guinea and Fiji.

The right products for the job

Winch Hire Australia National Sales Manager Troy Moulder says the use of winches is mandatory for relining works as it would be impossible to complete projects safely and efficiently otherwise. Currently, the company’s most common winches used throughout the lining industry are the 3 t electric winches and the 4 t, 6 t and bigger 10 t diesel winches.

Mr Moulder says Winch Hire Australia is always looking at ways to improve methods of hauling, with more products expected to be supplied in the future as they are developed and manufactured.

“We have invested more than 24 years in the industry, continuously improving our equipment to the latest technology,” he says.

In addition to supply services, Winch Hire Australia also provides its customers with onsite assessment and evaluation through reliable, direct communication with its experienced staff.

A rear view of one of Winch Hire’s winches, which are available as diesel or electrical winches.

Building ‘go-to’ relationships

Mr Moulder says over the past 13 years, Winch Hire Australia has worked closely with Interflow on a wide variety of projects, which has allowed a great relationship to develop between the two teams.

“One particular project comes to mind where we supplied our 4 t ZAD WINCH to assist Interflow with the relining of a series of pipes at Southport Spit, Queensland,” he says.

“You could say we are the ‘go-to’ company when they require hauling equipment. Matt Power, Branch Manager of Winch Hire Australia, has built a standing relationship with the team at Interflow over the years; understanding their projects and the types of equipment that they require to get the job done safely, efficiently and on time.”

Winch Hire Australia also supplies many other companies with lifting or hauling equipment, having been involved in many major projects including the Clem Jones Tunnel in its base city, Brisbane.

“There is no project too big or too small for Winch Hire Australia,” says Mr Moulder.

The use of winches is mandatory for relining works as it would be impossible to complete projects safely and efficiently otherwise.

A wide range of relining successes

With the company’s longstanding philosophy “keep it running”, Rangedale offers the expertise, capability, resources and scale to take on projects large and small – evident in its recent relining successes throughout the state.

The trenchless technology expert has added new systems to its existing range of rehabilitation products and increased its relining capabilities, which now include ultraviolet (UV) lining, inversion, fibreglass patching and Smart Lock technologies.

Rangedale has exemplified its capabilities on a recent major infrastructure project utilising the use of high-definition CCTV, high-pressure water jetting, patching and UV lining over a two-month period to rehabilitate the damaged storm water assets.

Due to the heavy-traffic location, Rangedale was required to create a works methodology to offer a solution that avoided disruptive excavation work. First, Rangedale used its CCTV cameras to ascertain the asset’s condition and completed drain cleaning requirements to mitigate any sharp or other potential hazards that could damage the liner during installation.

By using its new state of the art relining system, Rangedale used UV light during the installation process to reduce curing time, increasing productivity and allowing a cost-effective trenchless rehabilitation solution with minimal impact to key stakeholders and the community.

On another recent project, Rangedale continued to demonstrate its relining capabilities by completing a 100 linear metre UV reline on a DN 225 live sewer. Rangedale said concrete slurry from adjacent construction works infiltrated the sewer network then cured, causing a significant blockage issue.

The use of specialised robotics were then implemented by Rangedale for a duration of approximately two weeks to remove the concrete with cutting and grinding tooling.

Upon completion of the removal, Rangedale installed the liner to rehabilitate the damaged sewer.

The UV system consists of a flexible tube made of glass fibre that is impregnated with a reaction resin composition and then pulled into place in drains and expanded using air pressure before the curing process is completed. The finished product is a statically stable, seamless, flexible pipe.

Turnkey solutions

Rangedale offers complete in-house, innovative turnkey solutions, providing the best rehabilitation technologies and methodologies while ensuring the asset owner and end user receive great value.

For these listed projects, Rangedale installed approximately 50 Smart Locks that were manufactured locally and specifically for the task, including sizes of DN 825, DN 1050, DN 1800 and DN 2250, demonstrating the company’s full service approach to its projects.

Rangedale’s relining methodologies can be employed for all pipe and sewer rehabilitation and are applicable to drainage materials such as concrete, steel, vitrified clay, fibre cement, glass reinforced plastic, un-plasticised polyvinyl chloride, high-density polyethylene and cast iron.

By using its new UV lining system in collaboration with existing rehabilitation solutions, Rangedale can reduce curing times and provide a cost-effective rehabilitation solution through an environmentally friendly process.

Aussie Trenchless moves FNQ project forward

As trenchless technology continues to make its mark as the preferred installation method for underground infrastructure, Aussie Trenchless remains at the forefront of the industry with innovative new products and technology.

Growing in popularity

The company’s flagship product is a close fitting structural spiral ribbed PVC trenchless pipe lining system titled the SRP EXP. Used for circular sewer and storm gravity mains, the method continues to grow in popularity and will now be used on the recently-awarded FNQ project.

When the SRP EXP is installed, asset operators will extend the service life of a system by more than 50 years. Although designed to fit standard size access chambers, the product is also ideal for tight spaces or those with limited access.

Since the installation process is its unaffected by running infiltration and does not require bypass pumping, SRP EXP is well suited to water applications, particularly as it also enhances the hydraulic characteristics of the rehabilitated asset.

Aussie Trenchless Director Chris Meredith says he has seen significant growth in the implementation of this trenchless solution both around the world and here in Australia, where it continues to be implemented in relining projects, including in its repeat customer Relining Solutions’ upcoming contract.

Major improvements were already evident in the middle of the Ravenshoe Project.

Customers keep coming back

Relining Solutions is not the company’s only repeat customer, Mr Meredith says, with an international customer based in Taiwan ordering more supplies to be delivered in September this year.

“In 2019, the customer purchased 50,000 linear metres and have since been installing that,” says Mr Meredith.

“They have now placed another order of 60,000 linear metres, which are being manufactured as we speak.”

Mr Meredith says the customer is an active player in the Taiwan sewer industry has been for a substantial amount of time, often using Aussie Trenchless supplies for its projects.

Mr Meredith adds that this is an example of how customers are taking advantage of the product, with the company also receiving lots of market feedback indicating it is one of the most financially viable and efficient systems available.

“Like all efficient trenchless methods, the spiral lining system helps ensure the project’s aboveground footprint is minimised as much as possible, which includes the land and environment itself, as well as the day-to-day lives of the public in surrounding areas,” says Mr Meredith.

A successful range

While the SRP EXP is at the forefront of Aussie Trenchless’ market offerings, the company’s Hot Sleeve Jacket is also popular due to its prompt resin curing times.

The Hot Sleeve is a tight-fitting heating jacket that is secured over a patch inflatable packer to reduce ambient cure period without any life reduction, saving operators up to 60 per cent in crew times.

The Ravenshoe Project beginning to improve after showing severe signs of deterioration.

Aussie Trenchless also offers the market a man entry lining system using transparent polypropylene lining panels for the rehabilitation of gravity sewer mains, namely its Pipe Segment Technology (PST). PST is easy and fast to implement with lining panels made of polypropylene material providing a smooth surface and excellent hydraulic performance characteristics.
