Wastewater treatment is a complex and expensive operation - and one that is vital to protect our health, the environment and our quality of life.

 

South Australia led the nation in installing wastewater treatment systems and was the first Australian capital to achieve secondary treatment of all wastewater.

 

SA Water’s metropolitan wastewater system serves Adelaide's population through more than 7000 kilometres of sewer pipes and three major wastewater treatment plants: Bolivar, Glenelg, Christies Beach as well as a small plant at Aldinga.

 

In the county we manage 19 of the 20 wastewater treatment plants, with the Victor Harbor plant privately operated under contract.

 

You may not know that wastewater is 99.9% water, with the remaining 0.1% generally dissolved or suspended materials. Every day more than half the fresh water Adelaide uses is returned to sewers from household toilets, sinks, showers and washing machines. Added to this is wastewater from industries.
