The way to go in WA

With a primary objective of protecting the new water main during operations, a lower profile kwik-ZIP spacer model was used – demonstrating the manufacturer’s versatility.  

kwik-ZIP® General Manager Paul Jeffreys said the project involved abandoned gas mains with numerous internal protrusions, such as joints and welds.  

Because of this, there was significant concern that the PE carrier pipes for the new water main could be scratched and damaged during the slip lining operations.  

However, thanks to kwik-ZIP’s wide range of spacer models, the lower profile HD-30 spacer was used on the project to help ensure the water main was protected.  

Mr Jeffreys said the curved bow spring design ensures PE carrier pipes can easily ride over any protrusions and therefore be protected from damage.  

“HD spacers are also fitted with grip pads to prevent spacers slipping on the carrier pipe during installation,” he said.  

While HDPE pipe manufacturers generally advise that HDPE pipe needs to be de-rated in regard to its pressure if scratches exceed 10 per cent of the wall thickness of the pipe, kwik-ZIP’s spacers negate such need thanks to the inbuilt flexibility.  

“This highlights the benefit of using kwik-ZIP spacers for slip lining applications both inside an enveloper, and in open boreholes,” said Mr Jeffreys. 

“The runners ensure that the pipe can’t make contact with the enveloper during and after installation.”  

Wide range of products and capabilities kwik-ZIP’s large array of spacers caters for a wide range of inner diameter and outer diameter combinations as well as providing flexibility to deal with various project requirements and alterations.  

Site Engineer Jo McAnulty for the WA water main project said the kwik-ZIP spacers were a great solution for slip lining, alleviating the risk of potential damage to the PE pipe during the process.  

“Thanks to PJ and the kwik-ZIP team for their excellent customer service, they were fantastic to deal with from start to finish and we’ll certainly keep them in mind for future projects.”  

In addition to their proven success on this project, kwik-ZIP’s spacers are also often used on metro tunnel works, rail crossings and pipeline duplication projects thanks to the simple and efficient installation process that does not require any tools.  

kwik-ZIP spacers have no metal parts and are made from the company’s engineered thermoplastic blend that is flexible, extremely tough and has a low co-efficient of friction.

WSAA gives kwik-ZIP tick of approval

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.

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.

Primus Line repairs seaport pipeline

The existing HDPE potable water pipeline, which runs along and under one of the main roads into the port, required rehabilitation.

Due to its location, a dig-and-replace option was not viable as the port facility operates 24/7 and a part of the pipeline passes through areas of cultural heritage sensitivity where digging is not permitted.

For the rehabilitation, 1,500 m of Primus Liner DN 150 was installed with the lining in three sections, taking less than four days to complete.

The Primus Liner was installed in only four days.

Consisting of a flexible Kevlar® reinforced liner and specifically developed end fittings, Primus Liner is a flexible sliplining solution for the trenchless rehabilitation of pressure pipes.

Cape Lambert is a seaport exporting iron ore with an annual capacity to handle 80 million t.

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.

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.

Downer using innovative methods in Tauranga

In order to minimise surface disruption and the impact on adjacent environments, Downer is using Pipetech’s PressureLining technology, which results in a new polyethylene pipe within the host pipe in need of maintenance or replacement.

A dye that the new pipe is drawn through before entering the host pipe causes a reduction in size by up to 10 per cent, which is enough to allow the new pipe to be drawn through without risk of obstruction or damage.

The pipe will then return to its original shape within a few days.

This method also eliminates the issue of how to secure the redundant asbestos cement pipe, as in Tauranga’s case pipe bursting was an unavailable option.

Pipetech was acquired by Downer in 2017.

For more information visit the Downer website.
