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 the City’s population through a 7070 kilometre network of sewer pipes and three major wastewater treatment plants: Bolivar, Glenelg, Christies Beach and a small wastewater treatment plant at Aldinga.

 

In the county SA Water manages 19 of the 20 wastewater treatment plants, with the Victor Harbor plant privately operated under contract.

 

Wastewater is 99.9 per cent 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 it is wastewater from industries.
