Insituform’s new high strength junction seal

Latseal consists of silicate resin reinforced with a woven glass providing superior strength and thinner wall thickness than traditional glass felts, but it’s underpinned by two further advancements.

First, an error-proof, pre-packaged resin that improves the quality of the final cured product through dependable and repeatable mixing consistency, with an added environmental advantage including application controls to eliminate spillage or site mess.

Secondly, Latseal is installed using an innovative, patent-pending packer system to insert, inflate and install the seal.

This new packer design makes the installation process safer and a quantum step faster, saving time on site and costly rework.

Insituform’s first Latseal sealing truck modifications have taken place, with in-the-field training modules rolled out with crews and operators.

The company anticipates all Insituform crews will employ this technology nationwide within months.

Insituform is a part of the Killard Group.

Managing employee safety as an essential service

While many Australians are staying home during the COVID-19 pandemic, those working in essential services like water and wastewater are out in the field ensuring community needs are met.

The site operations have changed dramatically in an effort to keep employees safe and ensure business continuity, and while a lot of companies are in uncharted territory as they deal with COVID-19, adaptability and communication have emerged as the best way forward. 

Water infrastructure specialist Interflow has adapted its operations to ensure it can continue to help solve customers’ problems in the field while also taking the necessary steps to protect its people. 

Interflow Executive Manager for Health Safety and Environment Adrian Smith explained the company was putting enterprise risk management plans in place for COVID-19 in February.

“COVID-19 has created significant changes to the way we work,” said Mr Smith.

“We’ve implemented a Business Continuity Plan with five response teams to identify and resolve critical issues around workforce protection, supply chain stabilisation, customer engagement, operational lead and lag management, and stress testing financials.”

By using similar parameters within its current health and safety strategy Harm 2 Zero (H2O), Interflow’s response teams meet twice a week to discuss any necessary issues and actions.   

These additional safety and procedural policies include implementing social distancing; reinforcing hygiene as a top consideration; providing COVID-19 appropriate level of PPE for workers; ensuring up-to-date signage across all sites; and giving teams the right information so they are across all new company procedures. 

“We’re currently developing a second communication pack for workers, with updated rules of engagement, and every week our Managing Director creates a video message to all employees,” said Mr Smith.   

“In this current situation, we are classed as essential and the most important thing is having our field teams across the details of what we are doing to manage this crisis.” 

Open communication has been key to Interflow’s response, with a focus on using appropriate channels to disseminate updates.

The business also ensures information not only cascades down to all frontline workers, but also any issues from work sites filter back up to management. 

With a workforce spanning Australia and New Zealand, Interflow has also been keeping on top of all health and government changes on a national and regional level to ensure the business remains compliant. 

“Our clients see us as a valuable business partner – as an essential function to assist with their continuity,” said Mr Smith.

“We’re here to solve our customers’ problems, we’re able to adapt, and our response to COVID-19 has allowed us to connect as one team quickly and efficiently.”

Interflow will conduct a post-implementation review once operations return to normal to capture key information of what worked and what didn’t, which will provide vital learnings for the future.

Major sliplining upgrade commences

The $1 million upgrade to the regional outfall system will help ensure wastewater service reliability for major industry infrastructure, including Australian Paper’s Maryvale mill.

Gippsland Water Managing Director Sarah Cumming said the system was built in the 1950s to transport wastewater throughout the region and has since continued to play a key role in Gippsland’s economy.

“An important section that passes under the highway at Flynn is ageing and needs to be replaced,” she said, noting the works would not involve digging up the highway.

“By slipping the new pipe through a carrier pipe installed when the highway was upgraded, we can complete the work without disturbing the road.

“Having said that, as the works will take place adjacent to the highway, and will result in increased construction vehicles, the speed limit will be reduced for a short section of the Princes Highway at Flynn.”

Contractor Fulton Hogan commenced the work in mid-March with completion anticipated in the next three months.

WATCH: Bundaberg sewer relining project

The Bundaberg Regional Council Network Program Coordinator Geoff Tansley said the program was focusing on older and “at risk” sewer pipes.

“The most risk and consequence are normally associated with large high flow sewer mains and locations near roads, rivers, creeks or stormwater,” said Mr Tansley.

“Most of the sewer mains being relined in the current program are between 50 to 70 years old.”

Work will continue over the next few months, but Mr Tansley ensures residents will be mostly unaffected from what is happening underground.

“As the [relining] process happens from within, it eliminates the need to interrupt the service and has little impact or interference with traffic and residences,” he said.

“Those residents who have a sewer chamber within their yard will have a letter delivered and a worker will also speak to them to discuss the work and individual impact.

“Other residents within the work area will only have a notice delivered to property to explain the work and the expected timing.”

The current program is expected to be completed by the end of May 2020, yet the council said plans are already in place for future work.

“Water Services has established an associated program of proactive cleaning, survey and condition assessing our entire sewerage system to identify and quantify any defects in the network,” said Mr Tansley.

“The information gained from this survey will be used to identify, cost and establish a rolling program of relining work for the future.”

Melbourne Water completes sewer upgrade early

The $35 million project saw a 7.2 km stretch of the sewer upgraded to ensure surrounding residents continue to receive a secure and reliable sewerage service.

The works included relining the inside of the existing sewer with new plastic sleeving, rehabilitating more than 70 ageing and damaged manholes and decommissioning others that were no longer needed.

Following the upgrade, the main sewer now transports about 24 million l of wastewater each day to the Western Treatment Plant.

Melbourne Water Project Manager Tom Ryan praised the project’s delivery partners CPB and the Black and Veatch joint venture for the ability to complete the works before the deadline.

“We did this by having a number of crews working in multiple locations at the same time, which allowed us to complete the works more quickly and efficiently,” he said.

By using trenchless technology, the important cultural and environmental values of the local area were protected.

Melbourne Water worked closely with other agencies on the project including Moonee Valley City Council, Parks Victoria, Wurundjeri Land Council, Friends of Maribyrnong Valley and Friends of Steele Creek.

“We could not have completed this important sewer upgrade without these strong partnerships,” said Mr Ryan.

Mr Ryan said the focus of the project was now on reinstating areas affected by the work activities, in accordance with plans approved by Council and Parks Victoria.

Melbourne Water staff will continue to deliver vital projects while adhering to the latest State Government health measures during the COVID-19 pandemic.

Aussie Trenchless protects stormwater culverts

Aussie Trenchless on top down under

Aussie Trenchless’ most popular product is a close fitting structural spiral ribbed PVC trenchless pipe lining system known as the SRP EXP. Used for circular sewer and storm water gravity mains, the method has seen an increase in popularity both in Australasia and abroad thanks to its versatility and ease of use.

SRP EXP can be fitted to both standard size access chambers as well as tight spaces with bad access, with the product available for asset profiles from DN 150 to DN 1200. It enhances the hydraulic characteristics of the rehabilitated asset, making it particularly well suited to water applications, while the installation process is unaffected by running infiltration and does not need bypass pumping.

Recently, the spiral lining system was called upon to rehabilitate two corrugated steel stormwater pipes for the Tablelands Regional Council in Queensland, known as the Ravenshoe Project. The pipes were each 750 mm in diameter and 33 m long and while other contractors were approached to rehabilitate the pipes, only Relining Solutions wanted to attempt a project of this calibre.

The pipes were in what could only be described as horrific condition and basically had no base left after rusting away over the years. The only feasible application was Aussie Trenchless’ spiral lining, as this would be a size for size rehabilitation and would have minimal risk of collapsing the existing pipe walls.

With other methodologies the risk of collapsing the walls would be very real, which would possibly result in a need to dig up the road. Being the only road giving the residents access to their properties, this would have been a major concern as digging would be a minimum of one week construction and disruption.

Relining Solutions used the 600 cage and Profile E20 for the application and the contracted engineer was very pleased with the final result and signed off the project with no hesitation.

The corrugated steel pipes at the Ravenshoe project were in terrible condition.

More in the arsenal

While the SRP EXE is at the forefront of Aussie Trenchless’ offerings to the market, the company’s Hot Sleeve Jacket is a product that remains popular among customers. The Hot Sleeve induces a speedy resin cure during patch and seal lining activities which operators are finding can save up to 60 per cent in crew times.

Aussie Trenchless has impressed the market with its Pipe Segment Technology (PST) and its Hot Sleeve Heating Jacket. PST is a man entry lining system using transparent polypropylene lining panels for the rehabilitation of gravity sewer mains.

The Hot Sleeve is used by Aussie Trenchless customers to induce a speedy resin cure during patch and seal lining activities. Estimated to save up to 60 per cent in crew times, the Hot Sleeve is a tight-fitting heating jacket that is secured over a patch inflatable packer to reduce ambient cure period without reducing its life.

Aussie Trenchless has also caught the industry’s attention with its Pipe Segment Technology (PST) – a man entry lining system using transparent polypropylene lining panels for the rehabilitation of gravity sewer mains. Easy to build and fast to implement, PST lining panels are made of polypropylene material which provides a smooth surface with excellent hydraulic performance characteristics.

SA Water to replace watermains

As part of a $137 million investment from SA Water to refurbish 375,000 m of watermains around the state, pipes will be replaced along Main Street between North Terrace and First Street, with works to take approximately seven weeks to complete.

The new main will be made of PVC, replacing the aging cast iron and fibro cement pipes which have been in place for close to a century.

SA Water General Manager of Asset Operations and Delivery Mark Gobbie said the works will typically take place between Monday to Friday from 7.30am to 4pm.

“Soil movement, environmental factors and the weather means we can’t completely prevent leaks from occurring in our pipes, but we are committed to reducing their frequency and impact on customers through main replacements like this,” he said.

“This is one of a number of main refurbishments we’re undertaking across regional and metropolitan South Australia this year, and we look forward to continue working with communities across the state to improve water services for our customers.”

“We will ensure local residents are notified of any temporary water supply interruptions that are necessary when their connections are moved over from the old to new pipes.”

Kobus pulls through for Australasian market

Although leak detection is a growing field, pipe rehabilitation is an ultimately necessary solution when infrastructure begins to fail – a challenge faced across the globe. Fortunately for the industry, Kobus has continued to develop its high-value methods in this area with products and equipment applicable across water, gas and other service pipe sectors.

Australian reception

Since its first sale in the Australasian market, Kobus has seen an increase in volume of enquiries. As water and gas service lines are being upgraded and current infrastructure is being rehabilitated in many parts of the region, the works and subsequent demand Kobus is receiving are well aligned.

Kobus hopes that the Australasian market will take the technology on board as strongly as the US has, where after introducing the Kobus Pipe Puller a mere 18 months ago, the strong and consistent demand led Kobus to officially set up and open a facility in Michigan.

While the technology still on its first steps in the new Australasian market, Kobus President Tom Atienza says all reports from its current customers have been positive.

“We are in talks with a few medium and large contractors throughout Australia, who are working in large rehabilitation projects where we have pitched our technology and they are strongly considering the KPP400 as the technology of choice,” says Mr Atienza.

KPP400

The KPP400 is an all-in-one pipe pulling unit specifically designed for ease when moving around the job site; the machine can be mounted on most 35/45 series compact excavators while the puller generates 27,000 kg driven from the auxiliary hydraulics of the excavator.

The KPP400 can replace lead, galvanised iron, copper or poly pipe and can tow in new copper or polyethylene pipe in a single operation. These services can be quickly and safely pulled out of the ground, replacing old pipes for new installations of up to 36 mm in diameter and of lengths up to 25 m.

Both time and cost efficient, the KPP400 can complete a replacement in a mere three minutes – for a typical 12 m line – and is an affordable solution for pipe replacement as maintenance costs are kept to a minimum.

As a low maintenance machine, Kobus says the KPP400 is deigned to give contractors the edge against other trenchless or conventional technologies due to an advantage on costs, speed and safety.

Additional services and support

Last year, Kobus opened its new US facility to not only support the American market but also the Australasian market through supplying machines, accessories, consumables and technological support.

“We are working hard to complete in full our [Michigan] facility, where we are already assembling machines. We also are gearing up on all fronts to ensure we can fully support current customers and new ones,” says Mr Atienza.

“We are looking to establish working relationships with local companies and build bonds within the local communities, so we can grow together.”

To establish these bonds locally and internationally, all customers who purchase a Kobus Pipe Pulling machine receive additional services such as a package that includes pulling cables to allow pulling to commence from day one.

Additionally, comprehensive training from qualified Kobus engineers is also provided to help train crews to use the machine, therefore optimising the success of the pipe replacements and ensuring the crew are working safely.

First in line for trenchless rehabilitation solution

The mild steel cement-lined pipeline DN 900 PN12 runs underneath a busy street and a highway access with two opposing bends of 22.5°. With only two access points and a myriad of project challenges, works had to be conducted with a flexible and adaptable trenchless solution – being the Primus Line’s flexible Kevlar® reinforced liner and corresponding end fittings.

This flexibility allows the Primus Line® system to be installed through consecutive bends up to 45° and the robust liner can also withstand bends of 90° depending on the pipeline characteristics.

Rehabilitation investigation

The section requiring rehabilitation was only approximately 140 m. Upon investigating this pipeline section, Primus Line developed two options for rehabilitating the trunk main.

Hunter Water could choose to either install one Primus Liner DN 500 PN16 with an inner diameter of 452 mm, which would grant Hunter Water a utilisation of under 25 per cent or install three Primus Liners DN 450 PN16 with an inner diameter of 396 mm, granting the utility a utilisation of nearly 60 per cent.

Installing three Primus Liners with the larger DN 500 was not an option as the liners could not entirely inflate inside a DN 900 host pipe, considering a minimum inner diameter of 1,000 mm or greater would be necessary.

Additionally, the friction coefficient of the Primus Liner is with a K-factor of 0.028 lower than the friction coefficient of the existing main. This showed Hunter Water through its calculations that a reduction in diameter would be acceptable, so the Primus Line 3-in-1 solution was chosen as the solution to obtain a higher utilisation.

During installation, Interflow threaded the Primus Liner through the manifold prior to expansion.

Project stages

Hunter Water assigned the installation of the project to Interflow, a pioneer in trenchless technology and the most experienced Primus Line installer in Australian to date.

The existing pipeline was extended at both ends with a customised reduction piece DN 900 to DN 1600 that created space for the three flanges. The reduction and the manifold were designed by Primus Line and locally produced by Hunter Water.

To reach the construction site, the Primus Liner was transported on three reels and then placed sequentially behind the start pit in line with the run of the pipeline. Each liner was marked with a different colour of tape to ensure that the hoses were at the correct positions of both pipe ends after insertion.

During insertion, the liners were combined and stacked then fixed with tape for identification and to keep their shape. After insertion by a pulling winch, Interflow threaded the liners through the manifold and brought them into shape one-by-one with compressed air.

Following the inflation process, the six connectors could then be installed. The Primus Line system’s entire installation was completed within one week, including a separate pressure test with 15 bar conducted for each liner.

This trenchless method enabled the Newcastle region’s busy traffic flow to continue smoothly without interruption, caused minimal impacts to the environment and allowed residents to continue with day-to-day activities. Additionally, this project was the first instance of the Primus Line 3-in-1 solution’s implementation outside of Europe and demonstrated great success for the Australian industry.

SA harnesses HDD power

Horizontal directional drilling (HDD) is a trenchless method suited to a wide range of underground utility installations, including telecommunications conduits. With its growing popularity in recent years, HDD has gained its reputation of being a reliable and economical method of laying underground pipelines for water, oil and gas and installing underground utilities such as electrical cables and telecommunications conduits for broadband networks.

HDD powers SA’s NBN

In 2012, the National Broadband Network (NBN Co) continued to gather pace in SA with a map released detailing the location of work to rollout the fibre optic network. The following year NBN Co awarded SA Power Networks a contract to complete the network’s construction.

The initial contract would see SA Power Networks design and construct the local and distribution network that runs fibre from a local communications exchange through each street in a coverage area.

It was the second NBN construction contract to be awarded in the state after NBN granted Syntheo – a consortium comprising Lease and Service Stream – a two-year contract for the rollout of fibre in SA in 2011.

By 2013, SA Power Networks became the prime NBN contractor in SA after NBN Co and the Syntheo joint venture mutually agreed the contract would not be extended. Then in 2016, SA Power Networks engaged Trenchless Pipelaying Contractors to work on the installation the new SA NBN.

Trenchless Pipelaying Contractors’ scope of works for the project included locating existing services, HDD of communications conduits, pit repairs and the installation and hauling of optic fibre cables.

At the time of publication, Trenchless Pipelaying Contractors’ works for the project were ongoing in various sites throughout SA.

HDD and telecommunications history

As society’s demand for telecommunications services continues to grow, the need for the installations of corresponding conduits and cables has increased – resulting in further prospects for the HDD industry.

Although still a relevantly new method, HDD for telecommunications installation has already demonstrated evidence of its success across the globe and prominently in Australia with the nation-wide roll out of the NBN and international connections.

Examples of this over the past few years include:

  • LRM Civil Services using HDD to drill through challenging rock presence in Melbourne’s northwest corridor to make way for the NBN installation
  • Maxibor using HDD to install a fibre link for NBN under a river and coastal wetlands
  • Coe Drilling using HDD for shore crossing and beach manhole installations to accommodate an international submarine telecommunications cable.

Internationally, HDI Lucas employed HDD to complete the Tuas South Cable Landing Project in Singapore for ongoing telecommunications works and an Indian power utility installed a 3,500 km fibreoptic network under Bangalore to replace its overhead powerlines.

With the method ensuring less environmental impact to sensitive areas, along with its ability to drill through challenging geography prior to cable installations and the mitigated effect on the public, HDD is a forerunning option for telecommunications installations.

Study shows NZ wastewater pipes in need of funds

According to the New Zealand Herald, a third of Wellington’s wastewater pipes are in poor condition while the rest of country is also struggling as its aging infrastructure follows decades of under investment.

Water New Zealand compiled a study showing 33 per cent of Wellington’s wastewater pipes are in poor condition with an average age of 51, despite an anticipated lifespan of at least 100 years.  

After multiple collapses and failures through the city, Water New Zealand Technical Manager Noel Roberts said more funding from councils across the country is necessary, albeit challenging due to competing requirements.

“Much of the network is underground and therefore not visible, so there is a temptation for councils to underspend on buried assets and make more visible changes to cities in order to keep rates low,” said Mr Roberts.

Last week, the New Zealand Government announced details of its $12 billion investment for infrastructure with transport receiving a total $6.8 million while spending on water infrastructure didn’t feature.

Despite the announcement, Prime Minister Jacinda Ardern said the government was making “huge progress” on water issues by working closely with local governments, although the funding stage of projects had not yet commenced.

Wellington Chamber of Commerce Chief Executive John Milford said that due to the recent failure of the city’s – and country’s – pipes, this work “can’t happen soon enough.”

The proof is in the pulling

Kobus is a pipe replacement expert known for its innovative pipe pulling techniques and equipment that is applicable across the water, gas and other service pipe sectors. Originally a UK company with a recently opened facility in Michigan, US, Kobus is now offering its Pipe Puller product range to customers in Australia and New Zealand.

Ageing water infrastructure is a challenge faced by countless cities across the world, with a rise in leakage and failing pipes creating difficulty for water companies to consistently deliver a clean, quality resource. Although leak detection is a growing field, pipe rehabilitation is a necessary solution when infrastructure begins to fail and Kobus Inc. has continued to develop its high-value methods in this area.

Why pipe pulling? 

Trenchless pipe pulling approaches aren’t new, but they do offer some major new advantages, and the technology offers utility companies innovation that is demanded, as well as reduced cost compared to other methods such as open cut excavation. Pipe pulling also minimises the risk of utility strikes as it extracts an existing pipe and then tows the new pipe in along the borehole created by the extracted pipe. 

Using the pathway of the old pipe as described creates less overall impact on the surrounding ground conditions and the technique can be adopted in very soft or rocky ground, as well as inclines, offering an alternative when moling is less effective. Additionally, by pulling the decommissioned pipe from the ground the potential for environmental waste is eliminated, while the old pipe can potentially be recycled or sold for scrap.

In an area where operations need to be as condensed as possible, such as a residential or high-density metropolitan zone, pipe can be pulled in space as small as 0.5 by 0.5 m. This further reduces costs as well as the impacts on the day-to-day lives of citizens.

The Kobus Pipe Puller

The KPP400 has been very well received in North America since it debuted, with the company now supplying the product to Australia and New Zealand based customers. 

The product is an all-in-one unit specifically designed for ease when moving around the job site. The machine can be mounted on most types of 35/45 series compact excavators including Bobcat, John Deere and CAT, and the puller generates 27,000 kg driven from the auxiliary hydraulics of the excavator. 

The KPP400 can replace lead, galvanised iron, copper or poly pipe and can tow in new copper or polyethylene pipe in a single operation. The Pipe Puller is relatively inexpensive in capital equipment terms and, while a machine such as this does require consumables on each pipe replacement, maintenance costs are kept to a minimum as the design is largely maintenance free. 

With a huge number of pipe repairs required throughout major cities along with the time, disruption and cost of traditional methods, equipment users will save significant amounts of money and effort per replacement, allowing for quicker returns on any machinery investments.

Interflow gains national recognition

The CCF is Australia’s peak civil construction industry body, acting as the nation’s advocate for developments within the industry.

To locate exemplars throughout the field, the CCF Earth Awards unveils leading prospects of infrastructure including roads, bridges, railways, marine structures and utilities.

Specifically, the event recognises civil contracting companies who have recently been involved in a project that has excelled in numerous categories, such as project management, innovation, quality, development and training, safety and stakeholder engagement.

On 22 November 2019, Interflow and John HollandKBR Joint Venture (JH-KBR JV) collected the CCF National Earth Award for its North Yarra Deviation project.

The North Yarra Deviation is a deep section of sewer located under the Stony Creek Backwash where the creek meets the Yarra River, transporting 15–20 per cent of Melbourne’s sewerage at approximately 1,700 L/s during peak dry weather flows.

To complete the project, Interflow assessed suitable technologies and concluded the SPR™ PE – Ribline spiral wound lining system was the most practical rehabilitation solution.

Approximately 75 per cent of the work was completed in a confined space which was successfully navigated by an experienced project team and expert subcontractors.

The North Yarra Deviation project demonstrates how collaboration and innovation can achieve success in difficult pipeline rehabilitation projects.

SA Water claims AWA prize

The award recognises the customer experience the utility achieved during the development of its smart water and wastewater network, which manages water and sewer mains across SA.

SA Water’s General Manager Asset Operations and Delivery Mark Gobbie said receiving the AWA award was an honour that brings a stamp of approval for the corporation’s pioneering use of technology.

“This is terrific recognition for our team who have worked tirelessly to utilise this technology in our water network and deliver better outcomes for our customers,” said Mr Gobbie.

“By using research to better understand smart technology we can detect cracks in our pipes based purely on acoustic noises, with the technology now a key feature of our water network in the Adelaide CBD.

“Our sensors detect around 200 environmental noises every day, and we continue to understand acoustic patterns to help distinguish cracks in our pipes from other sounds picked up by the technology.”

Since implementing the technology in 2017, it has already assisted SA Water in proactively detecting and fixing just under half of the water main leaks in the CBD area.

“This award shows our evolving approach in asset management and using precise data to better meet our customer’s needs and expectations while gaining a better understanding of the infrastructure itself,” said Mr Gobbie.

SA Water’s smart water network uses acoustic sensors, pressure and flow data, high speed transient pressure sensors, acoustic leak detection sensors, smart meters and water quality sensors to monitor the underground pipe network for faults.

Melbourne Water completes sewer relining

In January, Melbourne Water announced an AU$100 million sewer relining and manhole rehabilitation program comprising six different projects.

Included in the program was the Pascoe Vale Sewer Upgrade that has now been finalised through the relining of the sewer and rehabilitation of the maintenance holes located throughout Pascoe Vale and Strathmore.

Melbourne Water constructed 500 m of sewerage bypass pumping pipeline; cleaned 400 m of the sewer, removing all debris and sludge; relined and grouted more than 385 m of sewer which was in poor condition due to deterioration; and rehabilitated 16 manholes.

Reinstatement works within the area will now commence.
