We specialise in the long-term operation, maintenance and management of critical public and private assets and infrastructure – from water, power, transport, schools and hospitals, to major telecommunications.Discover this section
Behind the scenes, we are proud to provide the services that keep infrastructure working for our communities.Discover this section
Water mains, sewers, drainage pipes and gas lines may be hidden from view, but keeping them well maintained is top of mind for our clients. Working with Ventia for their mains renewal projects, means they can be confident of reliably delivering services to their customers with minimal disruption.
We choose and use industry-leading techniques for each type of mains pipe renewal. We use the existing pipe infrastructure and restore pipe structural integrity without the need for traditional 'dig and replace' process. This allows us to minimise disruption to the community and environment. It is also more cost effective for our clients.
We have strong experience in Victoria and are currently delivering renewal works in Queensland, South Australia and New South Wales.
Our pipe renewal capability is delivered through our Aqua-Pipe business.
Aqua-Pipe is a fully structural, trenchless water main rehabilitation lining technology with a design life of 50 years, exclusively designed for drinking water networks.
We use a water cured-in-place-pipe (CIPP) lining technology to rehabilitate existing water mains. It lines the walls of an existing pipe with a composite reinforced pipe, making it a ‘true’ trenchless technology.
We have performed several trials with clients, and delivered an Australian first to Queensland Urban Utilities, renewing a water main located in a challenging location.
We use steam cured-in-place-pipe (CIPP) lining technology to repair and renew storm water drains and sewers.
Developed by leading worldwide providers Insituform Technologies, this trenchless pipe-within-a-pipe solution has a design life in excess of 80 years, restoring structural integrity to damaged pipes.
The CIPP liner is a soft, resin-saturated tube free of joins. Closed circuit television (CCTV) is used to help operators guide the tube into the host pipe. During installation, steam is applied to the soft liner, making it expand and conform closely to the shape of the pipe being renewed.
Once cured, the now-rigid liner is bonded to the host pipe but not dependent on it for its structural integrity. Service connections are then restored using a CCTV-guided robot cutter.
CIPP lining technology is suitable for renewing deteriorating or damaged sewer and drainage pipes (150mm through to 2.5m) without having to use conventional dig-and-replace methods. The coating on both sides protects the tube during installation, ensuring a high-quality end product.
Our clients benefit in many ways from our use of this innovative technology:
We have been providing renewal services to Victoria's South East Water network since 2010, and have renewed over 100,00 metres of pipe, servicing approximately 10,000 homes.
Our clients trust us with renewing Australia's aging gas mains network, ensuring their customers receive a safe, secure and reliable gas supply.
We have nearly 10 years delivery experience, with a strong track record in the Victorian market.
Our gas mains capability includes upgrading gas mains from low and medium pressure to high pressure in both steel and polyethylene.
As part of the Australian Gas Networks’ Mains Renewal Program (MRP), a five year program across networks in Victoria, South Australia and Queensland, we are replacing the old cast iron pipes and unprotected steel mains with polyethylene pipes for several major utility providers.
This work reduces the risks of gas leakages and water ingress associated with ageing infrastructure as well as increasing the operating pressure required to meet our client's customers’ demands.
The process involves inserting new polyethylene pipe, a plastic material that's flexible and highly resistant to corrosion, inside the original gas main. This method means we don't need to dig up entire pipe trenches, minimising disruption for the community.
