Our services

Each year we supply more than 230 billion litres of water to South Australians via our extensive and largely hidden pipes deep underground across our cities, suburbs and towns.

Every day we are providing essential services and as one of the most efficient water utilities in Australia, we are continually improving the way we do this for our customers, to keep prices as low and stable as possible over time. To deliver on our commitment to efficiency, we strive to make smart, long-term investments, and the best use of new technologies.

We remain focused on meeting our legal and regulatory responsibilities as well as what is most important to our customers.

Of Australia’s water utilities, we have one of the longest water mains supply network at more than 27,000 kilometres. In addition, we manage more than 9,000 kilometres of sewerage mains and a 413 kilometre-long recycled water network.
