Supporting housing growth

Growing our network to support housing growth

We are working closely with the State Government and industry leaders to develop effective water and wastewater solutions to support housing growth, driving the single largest expansion of our metropolitan water and wastewater network in decades. This expansion is crucial to supporting new housing developments located on the outskirts of our existing networks, particularly in Adelaide’s northern suburbs. These areas require large-scale infrastructure systems to ensure reliable water and wastewater services.

Unlocking new homes for the future

An investment of $1.2 billion over the next four years as part of the housing roadmap will enable us to provide water and wastewater services to more than 11,000 homes. This investment will also fund the construction and upgrading of essential infrastructure that will serve as the backbone of our network, ensuring that we can support these rapidly growing communities.

Delivering critical infrastructure

The planned infrastructure improvements include:

• 25 kilometres of new trunk water mains

• 43 kilometres of trunk wastewater mains

• Four new pumping stations

• Two new water storage tanks

Work is underway with new projects starting in early 2025.

These upgrades will facilitate housing growth in Adelaide’s northern areas, including Roseworthy, Riverlea, Dry Creek, Angle Vale, and Blakeview.

Crucially, this infrastructure lays the groundwork for future expansion. With ongoing investment, the network will be able to support up to 50,000 new homes by the 2050s, paving the way for a sustainable and thriving future.

The delivery of this essential infrastructure will require extensive and complex work, predominantly in Adelaide’s northern areas. During construction, we will be operating across multiple sites and collaborating closely with local communities to minimise disruptions, ensuring that this vital work is completed efficiently and safely.
