Growing our water and wastewater network to support housing growth
We’re 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.

Minimising disruptions while we deliver
We’re working closely with local communities throughout construction to minimise disruptions and make sure the work is completed safely and efficiently. During construction, there may be traffic delays, detours, or other interruptions.

Connecting with the community
We’re keeping local communities and stakeholders informed as we deliver these essential network upgrades.

Unlocking new homes for the future
An investment of $1.2 billion over the next 4 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
- Two new water storage tanks
- 43 kilometres of trunk wastewater mains
- Four new pumping stations
Work is underway with new projects starting throughout 2025 and continuing over the next 4 years.
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.
Delivery program
This delivery program provides an overview of our program of works through to 2028.
Construction industry opportunities
Our two year forward plan provides an overview of our upcoming capital works program. This investment is creating new opportunities for the construction industry across 6 areas – major projects, water civil, water solutions, wastewater, regional, and minor works – with tender details available at tenders.sa.gov.au and upcoming opportunities listed at gateway.icn.org.au.
In November 2024 we briefed the construction industry on our two-year forward capital construction plan through to 2026 which will grow and maintain our water and wastewater networks. It covered our procurement approach and opportunities for the construction industry to get involved. You can watch a recording of the briefing below.
