THE GLENELG WASTE WATER TREATMENT PLANT (WWTP) is one of three large wastewater plants in metropolitan Adelaide, South Australia, a city ranked in the top 10 of The Economist's "Worlds Most Livable Cities." The plant, located in Western Adelaide, covers a drainage area of approximately 92 square kilometers (36 square miles) and serves a population of about 200,000 persons. The treatment plant is a conventional activated sludge plant that incorporates screening, grit removal, primary sedimentation, activated sludge, secondary clarification, sludge removal, sludge digestion, power cogeneration and effluent disinfection by chlorination prior to discharge into the Gulf of St. Vincent, a beautiful stretch of coastline used daily by the citizens of Adelaide. Portions of treated effluent are also reused for irrigation of golf courses, playing fields and recreation areas via the Glenelg to Adelaide Parklands (GAP) Recycled Water Project.
