SOLVING NORTH LIMA'S WASTEWATER POLLUTION WOES
Abstract:A study was performed to evaluate 24 alternatives for wastewater treatment and disposal for the North Lima Metropolitan Area in Peru. The alternatives involved ocean outfall lengths ranging from 3 to 8 km and wastewater treatment ranging from screening to secondary treatment. Based on receiving water quality modeling studies and an evaluation of environmental factors, costs, and other criteria, the preferred option was identified and involves primary treatment with an 8-km, 4-m diameter ocean outfall. Preliminary engineering designs were prepared for the treatment plant and outfall, which would cost approximately US 420 million. The proposed facilities would serve a 2024 population of approximately 6 million, with an average flow rate of 14.9 m3/s.
