kwik-ZIP gets the show on the road

The kwik-ZIP HDXT Series is an anti-corrosion, non-metallic casing spacer range for pipe-in-pipe (PIP) applications such as slip lining and cased crossings.

Suitable for heavy-weight pipe materials including steel, ductile, mild steel cement lined (MSCL), glass reinforced epoxy (GRE), polyvinyl chloride (PVC) and high-density polyethylene (HDPE), it can be used on all diameters from 300 mm and beyond through the simple addition of multiple segments.

Kwik-ZIP HDXT-43 spacers were recently used on a project for Highways England on a M42 J6 diversion in Birmingham. UK-based infrastructure services and engineering company Amey used the spacers to facilitate the slip-lining of a four-pipe bundle.

Junction 6 of the M42 connects the M42 motorway to the A45 to the east of Birmingham, where road users suffered significant delays and due to capacity constraints. The M42 J6 Diversion Project was designed to alleviate some of these delays experienced by motorists.

The 4-pipe bundle consisted of 2 x DN 180 HDPE and 2 x DN450 HDPE pipes with a run length of 135 m. Kwik-Zip spacers were selected for this project due to their ability to secure the 4-pipe bundle together; their suitability to work with any pipe profile; and their design that protects and supports the bundle during the slip-lining process. 

Kwik-ZIP’s large range of spacers caters for a wide range of carrier and casing pipe size combinations, as well as providing flexibility to deal with project alterations. Kwik-ZIP spacers have no metal parts and are made from Kwik-ZIP’s engineered thermoplastic blend that is flexible, extremely tough and has a low co-efficient of friction. 

Amey site manager on the M42 J6 Diversion Project Tim Lohoff commended kwik-ZIP for the intuitive design and ease of use of the spacers, which helped the project to come to fruition. 

“The spacer system was easily installed and was an excellent aid in slip lining the 4-pipe bundle through the tunnel, which we had installed prior to slip lining works – a truly excellent product,” says Lohoff.

SECA promotes emissions reductions with the eCityJet electric jetting machine

The eCityJet is a fully electric jetting machine incorporating the newest technology with an electric motor powered by a battery pack. The machine generates zero emissions, making it a future-conscious choice, and ideally suited as a van-pack for use in city centres where strict emissions requirements apply.

The eCityJet has all the features of a conventional diesel-driven van-pack machine but offers emission-free operation without compromising on performance.

The eCityJet is also virtually silent during operation. As well as a cleaner choice, electric technology is quieter than diesel operated machinery, making it ideal for urban, indoor or night-time use.

The machine weighs 690 kg when empty and is most suited for cleaning pipes with diameters of up to 350 mm. Lightweight and compact, the eCityJet is suitable for most vehicles.

Lithium-ion batteries have the highest energy density, making them the most efficient in terms of weight and space and ideal for mobile application. The eCityJet battery is chargeable through regular mains. While use at full power is designed to last just over 1 hour, customers have reported using the machine over 2 or 3 days on 12-14 jobs on a single charge.

Enter the Hybrid Jetting & Inspection Vehicle

Since releasing the eCityJet, SECA has fitted out the jet-packer into a fully customised Hino Hybrid Truck. Hino has improved the design of its diesel electric hybrid system to maximise efficiency, reduce fuel consumption and provide owners with a low-maintenance and trouble-free driveline.

The components that support the hybrid system have been redesigned to reduce weight and take up less space and deliver greater performance.

SECA has also fitted out the hybrid truck with its Rovion crawler system. The Rovion CCTV inspection system is Australasia’s most popular CCTV pipe inspection system, for small and large pipes.

This mobile crawler is designed to reduce setup times without the use of tools. All components are individually pressurized and monitored for more reliability and faster setup. It is also scalable, with all components fully compatible with each other.

While SECA is not in the business of selling vehicles, the company does offer customised fitouts to vehicles to cover the hybrid option with the emission free jetter. This makes it a flexible and adaptable solution to operators working across a diverse range of conditions and environments.

Case study

London-based drainage firm Kwik Jet was the first UK contractor to put Rioned’s eCityJet into daily operation. The family business has been a long-term user of Rioned machines and the acquisition of a new electric van-pack jetter has helped the company to achieve sustainability objectives.

The firm has been operating in Central London for the past 30 years, with its core offering being the maintenance of drain networks for some of West London’s most prestigious property management companies.

Managing director Michael Morris said the company decided to purchase an eCityJet because of their long-term relationship with Rioned and because of their drive to debut new technology.

Morris admits that when he first heard about Rioned’s electric van-pack, he was sceptical about the capability of a batteries to handle the daily workload. However, the eCityJet surpassed his expectations.

“I must say, we are very impressed with the eCityJet’s performance so far when compared to our previous van-packs,” says Morris. “As the switch to renewable energy continues, this type of machine will become essential for use within the city centres where strict emission requirements apply.”

The Kwik Jet team reported they have also received far fewer complaints concerning noise and none regarding fumes since making the switch to the electric-motored jet.

“We aim to have an all-electric fleet by 2030 and feel the use of electric vehicles and machines is the way forward for the drainage sector,” Morris says.

The key to long-lasting plastic pipes and fittings

The Plastics Industry Pipe Association of Australia (PIPA) was founded in 1999 and is the peak industry body representing manufacturers and suppliers of plastic pipes and fittings, plastic resin suppliers, fabricators, pipeline installers, rubber seal ring manufacturers along with training and certification bodies.

As a non-profit association, PIPA works to promote the appropriate and contemporary use of plastic pipes and fittings throughout Australia.  This is achieved through our four key pillars of advocate, educate, technical and sustainability.

Executive General Manager Cindy Bray says Australia’s vast landscapes require large-scale, special purpose systems to move water, wastewater, gas and to protect underground networks of power and communication cables.

“We know that potential that plastic pipeline systems provide for long life, sustainable infrastructure that supports the circular economy,” she says.

“Not only are plastic pipes smart, efficient, and sustainable but so are the trenchless installation methods used. Plastic pipes are the preferred choice to replace and upgrade other pipes throughout the world. This is due to their performance, durability, service life, simplicity of installation, energy efficiency, recyclability, and overall cost effectiveness.”

PIPA’s sustainability story

To help educate across a wide range of audiences, PIPA has developed key messages to tell its sustainability story. Not all plastics are the same and too often pipe systems are mistakenly put in the same category as single use plastics.

Plastic pipe systems deliver essential everyday services and utilities

When thinking about the network of pipelines under the ground there are many vital roles they play from delivering drinking water, gas and electricity to homes and communities.

Bray says the network of wires and cables that deliver internet and communication services are used in irrigation systems that are essential for growing food.

Plastic pipes also carry away sewerage, rainwater, and stormwater – protecting communities.

“In recent years the water industry has also embraced PE particularly when trenchless installation techniques like directional drilling, pipe cracking, slip and swage lining have led to increased usage in water and wastewater applications,” she says. “These allow for fewer disruptions during installation or repair of existing pipelines, allowing flexibility and cost-effective installation of pipelines without the need to excavate trenches, lowing the impact to the environment and the community.”

Engineered products designed to last

Plastic pipes are long-life products, not single-use and are made from material engineered to be robust, reliable, and recyclable. With a service life longer than 100 years, the pipes are engineered from polymer materials and the perfect choice for infrastructure applications.

Unlike many plastic packaging applications which have multiple layers, plastic pipes are made from a single material and therefore easier to recycle.

“Plastic pipes used in buried infrastructure applications, like water, will likely never be dug up even at the end of their long service life. Instead, they will likely become a host for a new plastic pipe through trenchless installation, saving huge amounts of energy, resources, significantly reducing the impact to the environment,” Bray says.

Safe for people and the planet

Plastic pipes provide the highest level of safety for carrying drinking water and are manufactured to Australian standards.

Offering clear advantages in terms of chemical resistance over other pipe options, they are not affected by soil environments that are highly corrosive to metals and concrete.

Plastic pipes are not affected by compounds that form in wastewater such as acids that rapidly degrade iron and cement-lined pipes, making them the ideal choice for long-term infrastructure.

“Using plastic pipe systems in trenchless applications minimises the environmental footprint and is the best choice for digging under creeks, rivers, and other environmental sensitive areas,” Bray says.

The smart choice, using recourses responsibility and sustainability

Most plastic pipes are still in its first lifecycle and therefore recycling rates remain low, with most buried infrastructure applications becoming host pipes, minimising the impact to the environment using trenchless installation.

Bray says life cycle analysis studies have shown plastic pipes have a significantly better environmental profile than alternative pipe materials in all categories and across its whole lifecycle. Trenchless technology installation also reducing carbon footprint, reducing energy use and the amount of pollution released in the atmosphere compared to open cut trench.

“You can see the environmental benefits of using plastic pipe systems with trenchless installation methods. By using resources responsibly through better design, we’re working smarter. We’re committed. And we’re working towards creating a healthier environment and sustainable future,” she says.

Rob Carr continuing to take steps to reduce carbon footprint

Emissions reduction is arguably the most significant topic for debate in the community and has been for some time. It is now apparent that all individuals and organisations have a role to play in taking responsibility and being conscious for their carbon output and making changes where they can.

Leading the way for a decade

Rob Carr is proud to be leader in the research and development of microtunnelling and other trenchless technologies in Australia and New Zealand. Back in 2012, the company supported research into how microtunnelling could be used to reduce emissions – the learnings of which were subsequently put into practice.

Through the Griffith School of Engineering, Rob Carr Project Manager Jaime Leal undertook an investigation into the emissions generated from trenchless versus conventional open cut methods. The purpose of the research was to compare the carbon footprint of microtunnelling, based on data from a number of projects carried out by the company, with projects which used conventional construction methods.

Mr Leal’s research found the emissions produced by microtunnelling was dependent on the size of the microtunnel boring machine (MTBM) and the soil conditions, while emissions from conventional construction were strictly related to the depth to invert level of the installation.

The main comparison, where both construction methodologies comprised an identical scope, included a 3.5 m deep invert level pipeline in sand, sandy clay and gravel. The microtunnelling method was established to produce only 47 per cent of the amount of CO2 emissions produced by open cut.

The thesis also found the fuel consumption of microtunnelling was dependent on geology and the tonnage required to push the MTBM thorough the ground. As a result, concluded that at a depth of 1.9 m – in clay, sand or gravel – microtunnelling became more economical and was the most advantageous technique for pipeline installation.

Environmental action plan

In 2020, Rob Carr’s parent company, Soletanche Bachy, mandated that all of its subsidiaries around the world would be required to produce an Environmental Action Plan designed to reduce emissions by 40 per cent by 2030. It was stipulated these plans had to target three key areas of improved efficiency: fuel, electricity, and water.

To meet these objectives, last year Rob Carr installed solar power generation at the company’s warehouses in Yatala, Queensland and in Welshpool, Western Australia.

In addition to office space, at Yatala the system had to be designed to cater for an onsite fabrication facility which uses a considerable amount of power. A 39 kW system is now in place, featuring 128 solar panels, with approximately 4 kW of redundant power directed back into the grid. In Welshpool, a 9 kW system made up of 24 panels was installed and in 7 months of operation has reduced emissions by 6.76 t.

To tackle fuel reduction, Rob Carr’s fleet of generators has been updated with newer and more environmentally beneficial technology, while the company is also looking at introducing transformers on site and reducing the use of light vehicles on projects. In Yatala a more than 20,000 l rainwater tank has been installed under the warehouse, while water recycling processes are also in use.

“The results of our Environmental Action Plan will be assessed at the end of this year, at which point a new plan featuring new steps will be introduced,” says Rob Carr Safety, Health, Environment and Quality Manager Mark Fee.

“These plans need to be assessed regularly to ensure we know how we’re tracking against our goals. The early indications are that we are already exceeding the expectations set out by our parent company, are on track to exceed our 2030 target, and are committed to going further than that in the future.”

Yarra Valley Water completes Doreen to Diamond Creek Sewerage Project

Yarra Valley Water has successfully delivered the Doreen to Diamond Creek Sewerage Project after two years of construction works. Design works commenced in February 2018, with design consultant Jacobs contracted to discern if there were any culturally significant artefacts on the banks of the Plenty River.

Jacobs found close to 400 aboriginal stone artifacts over an area of several hundred metres, after which the contractor consulted local Wurundjeri to negotiate a different construction technique to the traditional open-cut excavation method.

Horizontal Directional Drilling (HDD) was deemed the most viable solution to protect the archaeological site from harm. As most archaeological artefacts are located within the top 50 cm of soil, trenchless technology can effectively bore while avoiding disturbance to any culturally significant sites.

As well as retaining cultural significance, reducing the need to excavate helped to maintain the integrity of the ecosystem. Yarra Valley Water was careful to ensure that works did not affect water or sewerage services in the area.

Construction works commenced in March 2019 and were completed in November 2021. The project involved the installation of approximately 10 km of pipe and 17 new sewer maintenance holes under parkland and road reserves in the Doreen, Yarrambat and Diamond Creek areas.

The new sewerage infrastructure will service properties in the rapidly expanding Mernda and Doreen areas, delivering greater system reliability to cater for rapid population growth.

The project will also reduce the likelihood of sewerage spills during heavy rain events, according to Yarra Valley Water general manager Chris Brace. By reducing the likelihood of sewage spills, Yarra Valley Water is also ensuring provisions to protect the natural environment.

“We’ve worked with our delivery partners, MFJ Constructions and Jaydo, to deliver the project, which is among the top 10 projects we’ve committed to complete for our customers,” Brace says.

Brace thanked contractors MFJ Constructions and Jaydo, and design partner Jacobs for their tireless effort during the project. “Our design partners Jacobs also salvaged almost 400 artefacts and we worked in partnership with the Wurundjeri Woi Wurrung Cultural Heritage Corporation to sensitively repatriate them,” Brace says.

Future-proofing CIPP liners and pipe rehabilitation solutions

Country Manager Kevin Woolf tells Trenchless Australasia that IMPREG recognised early on that trenchless pipe rehabilitation using cured-in-place pipe (CIPP) liners is the technology of the future. 

Further developing this avenue, the company’s CIPP liner systems are developed using innovative high-tech processes, and set new standards.

“Our success proves us right. IMPREG CIPP liner systems for UV curing are used all over the world,” he says. “We are a reliable solution partner at all times, and commit ourselves to the highest future-proofed quality and to environmentally conscious conduct.”

Woolf says the IMPREG liner GL16 was developed in 2016 for all common pipes from DN 150 up to DN 2000.

As a result of good material characteristics and new fibreglass design, IMPREG was able to develop a more finely nuanced gradations of wall thickness.


Not only does this benefit the company’s customers financially, but the IMPREG liner GL16 makes it easier to deal with large dimensions.

“Through the IMPREG liner GL16, the company has consistently extended its position as a technology leader in the market segment from DN 1200 upwards,” Woolf says.

“The unique construction of the IMPREG liner allows a certain level of compensation for dimensional variations in the pipe. We can produce defined dimensional changes in our factory.

“In the Australian Pacific region our range js GL16 which is made up of 0.8 mm fibre glass layers and inner foil, outer fleece and a yellow UV protection sleeve from DN150 to DN2000 with wall thickness ranging from 3 mm to14.6 mm.”

Woolf highlights that the high-tech CIPP liners from IMPREG are simply inserted into the pipes via the manholes, and cured using UV light. The rehabilitated pipe can then be returned to operation immediately after curing, with the company able to rehabilitate up to three pipes in a single day.

With a warehouse located in Brisbane, standard liners in Australia and New Zealand are available to be shipped across the nation, with the liners ready to go for: DN150, DN225, DN300, DN375, DN450, DN525, and DN600.

Woolf says the main aim for IMPREG this year is to continue supporting its customer both onsite and technically.

“Our biggest goal for 2022 is to continue our after market care,” he says. “The customers’ success is our success, meaning our after care is just as important as our product quality.”

As part of the company’s after market care in Australia, Woolf is able to help with structural designs, review CCTV on job sites and provide onsite technical support.

“New customers will also have the opportunity to attend a training session and find out how we already implement the trenchless pipe rehabilitation of the future,” he says. “Our application engineers are onsite for your first project, and support you with advice and assistance during the installation of the IMPREG liner.”

With no need to bring a project to a stop, IMPREG is also able to rapidly and effectively rehabilitate pipes which carry aggressive or higher-temperature waste waters.

“IMPREG CIPP liners are future-oriented, high-tech products which provide all options for the rapid, effective, and economical rehabilitation of pipes of very differing diameters,”says Woolf. “With our liners, we at IMPREG set new standards that will lead us into the future.”

Tracks laid for Metro Tunnel

Metro Tunnel crews are preparing to lay track through the completed tunnels, moving the project one step closer to enabling more than half a million extra passengers every week on the rail network. 

The first of almost 40km of rail has been delivered on freight trains to the Metro Tunnel’s western entrance in the past week as works gear up to install rail systems and tracks through the project’s twin 9km tunnels.

The tracks are made up of 165 m lengths of steel rail that will be progressively clipped to concrete panels and welded to form a continuous rail line along the lengths of the tunnels. 

According to City of Melbourne, installing the track will take up to a year, beginning with crews laying 4000 high-performance precast concrete panels through the twin tunnels.

There are 300 different panel shapes to account for the varying curvature and elevation of the tunnels as they wind from Kensington to South Yarra up to 30 m underground.

All rail will be installed by mid-2023 when trains will begin their first test runs through the tunnel. 

The Metro Tunnel is expected online by 2025.
