From urban utilities to remote communities, we deliver robust pipe and fitting solutions that keep critical infrastructure running smoothly. Our systems for water supply, sewage, stormwater and gas distribution are engineered to perform under pressure—literally—ensuring safety, efficiency and long service life.
Key challenges we address
Delivering safe, clean water
High-pressure transport of potable water across varied terrains and conditions.
Protecting public health
Wastewater management that ensures proper health and sanitation while offering high corrosion resistance.
Future-proofing essential services
Serving large networks and able to withstand heavy use, harsh climates, and decades of service.
our products
Water supply & distribution
We deliver high-pressure piping systems that move water efficiently from source to treatment, storage, and end users. Our solutions ensure reliable supply across cities and rural areas, supporting water treatment, reuse, and long-distance distribution. Low-pressure drainage systems focus on smooth pipe interiors and precise air management for optimal flow.
Sewage solutions
Our waste drainage systems handle the demands of both above-ground and underground sewerage networks. Resistant to corrosion and chemical damage, they safeguard communities while reducing maintenance costs.
Stormwater management
We design systems that capture, channel and treat stormwater to reduce flood risks. Our StormFLO® large-diameter pipes, with up to 65% recycled content, combine strength, durability and proven performance under heavy rainfall and highway traffic.
Gas distribution
Our electrofusion technology couples perfectly with our fully tested pipes to ensure safe and efficient gas delivery. From standard diameters to custom-engineered solutions our technology upgrades ageing networks for modern safety and performance standards.
Behind the scene of our products
Heat recovery solutions
In Canada, we helped Toronto Hospital meet 90% of its heating and cooling needs with renewable energy by capturing thermal energy from deep underground wastewater. Using our Vortex™ Flow system, we delivered a customised, low-maintenance solution that eliminated chemical treatments and odour control equipment, cutting greenhouse gas emissions and proving the power of sustainable infrastructure innovation.

Sustainability in the sector
Sustainability in infrastructure
Our infrastructure solutions are designed with sustainability, efficiency and longevity in mind. Using more recycled content and ensuring the recyclability of our products end of life means we’re ensuring our systems have a better lifecycle from cradle to grave. We strive to build networks that conserve resources, protect water quality, and deliver energy safely, all while delivering better value.

CASE STUDIES
Some of the ways we deliver for customers
From Annual Report 2025
Harbouring our best work
The New South Wales Government's Sydney Harbour Tunnel upgrade is one of Australia's most complex infrastructure projects — and the kind of challenge Aliaxis embraces.

Recycled pipe on the road
Our pioneering recycled-content HDPE twin-wall pipe, StormFLO® by Vinidex, has proven successful in Victoria’s North East Link road trials, being installed under a busy road. The pipe uses 65% recycled material. The trial was regarded as a great success – from StormFLO®’s ease of installation, requiring less mechanical movement than traditional options, to the excellent overall performance of the pipe recorded at each inspection. With Victorian Government support and industry endorsement, this innovation demonstrates how recycled materials can meet demanding infrastructure requirements.

Replacing ageing metal gas pipes in London
Around 2,800 km of legacy metallic gas pipes in central London needed replacing, to better serve the growing population. While our GPS polyethylene (PE) Yellow pipes were suitable, the existing pipes approved for use in the UK gas industry were too small in diameter. We manufactured, tested, accredited and delivered a new 800 mm pipe, and trained more than 50 installers to insert them into the existing pipe structure for a cost-effective transformation.

New water solutions
Modular systems and subassemblies are a growing area of innovation. In India, we successfully introduced a modular water storage system, using square water tanks that can be easily assembled to give municipalities greater flexibility in water storage capacity.

Porquerolles in France – a sealine, a lifeline
We’ve built a “sealine” underwater aqueduct, carrying drinking water from the French mainland to the Mediterranean island of Porquerolles, which relies on a water tanker during the holiday season. Carried out in two stages to avoid disrupting the tourist trade, the aqueduct now provides an all-year supply.

High demand for new infrastructure pipe
Our newly developed OPVC pipe allows safe water supply, providing excellent durability for high pressure water distribution as an alternative to metal pipes. We’ve upped production to meet demand as it has been specified by multiple states and supplied to the Indian government.
