Bolivar WWTP
Outfall

The Bolivar wastewater treatment plant is the largest sewage plant in South Australia and serves Adelaide suburbs north of the River Torrens and as far east as Glen Osmond. By using secondary level treatment, this plant discharges the treated water via 11 km outfall open channel to coastal marine waters at St Kilda north of the plant. Approximately 30% of treated wastewater is recycled for irrigation of market gardens at Virginia after treatment through the Bolivar Dissolved Air Flotation & Filtration (DAFF) plant. After additional chlorination, supply to dual reticulation network at Mawson Lakes.
