Our water & sewerage systems

Our water & sewerage systems

In this section you will learn how water is delivered to you and what happens to it after you've used it.

Supplying drinking water in South Australia is a big challenge. We live in one of the driest inhabited places on Earth and our population is scattered across a large area. While most of us think about the challenge of drinking water only during drought, it's been a big issue since settlement. Our rapidly developed expertise in managing and transporting water has played a vital part in the development of our state.

To get clean, healthy, high-quality water to your tap we take and treat water from a range of different sources. We then move this water to you through a complex, and extensive, network of pipes. Our operations span the length and breadth of South Australia.

While getting water to you is challenging, dealing with sewage is also complicated. Despite the complexity, we are proud that South Australia was the first state to install sewage treatment systems. And Adelaide was the first capital city to achieve secondary treatment of sewage.

Adelaide's sewerage system is made of more than 8700 km of pipes. Three major wastewater treatment plants at Bolivar, Glenelg and Christies Beach treat the water. We also have a smaller treatment plant at Aldinga.

Outside Adelaide's metropolitan area, there are 20 treatment plants. Of these, the only one that is privately operated is at Victor Harbor.

  • Some Adelaide Hills customers may notice changes in the taste and/or smell of their tap water, as we work hard to reduce the impact of an algal bloom in the Summit Reservoir.
    The algal bloom is causing a naturally occurring compound called geosmin, which can affect water taste and odour, but is harmless to health. The water remains safe to drink.
    We expect customers in the following areas may notice this change: Mount Barker, Balhannah, Oakbank, Verdun, Hahndorf, Heathfield, Stirling, Crafers, Lenswood, Lobethal, Woodside, Brukunga, Mount Torrens, Birdwood, Gumeracha, Kersbrook, Cudlee Creek, Wistow, Nairne, Littlehampton, Strathalbyn, Clayton, Milang, Langhorne Creek and Bridgewater.
    We have made changes to our treatment processes at the Summit Water Treatment Plant to reduce the level of geosmin in the water.    
    Our testing shows no algae has been detected in the network and it has been completely removed as part of our normal treatment process.
    If our customers have any questions or concerns, please contact us on 1300 SA WATER.
