Wastewater networks

Wastewater networks

South Australia has always led the water industry in sewerage treatment. We were the first Australian state to install sewage treatment systems. Adelaide was the first capital city to achieve secondary treatment of sewage.

While getting water to you is challenging, dealing with sewage is also complicated.

Adelaide's sewerage system is made of more than 8700 kilometres 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.

Protecting the environment

We are currently recycling and reusing 32 per cent of our wastewater, returning it to the community for irrigation of parklands, community grounds and also the horticulture industry. We are well on our way to increasing that amount so that we reach the goal of only returning one in every two litres of water back to the environment.

In the Adelaide Hills we are increasing the recycled water available to local businesses, growers and vineyards.

Smart technology trials are not only improving our wastewater operations, they are also receiving recognition in international awards. And our upgrades to pump stations in metropolitan Adelaide and in regional South Australia are reducing methane emissions.
