Full Description

To help combat potential water supply shortfalls due to drought, the West Basin Municipal Water District in Los Angeles, California, embarked on a major water reclamation project. The project takes treated secondary effluent from the Hyperion Treatment Plant and pumps it through a 60-inch forcemain to an advanced wastewater treatment plant. After further treatment, the reclaimed water is pumped through an extensive distribution system. The West Basin Treatment Plant will produce reclaimed water through two separate process chains. Landscape irrigation, industrial and commercial water is treated by chemical addition, flocculation, filtration and disinfection to meet California water quality standards for drinking water. Water used for injection into groundwater is treated with chemical addition, decarbonization, lime treatment, recarbonization, filtration, reverse osmosis, post-decarbonization and disinfection. Reclaimed water is pumped through an extensive distribution system. Reclaimed water users will include nurseries, golf courses, concrete plants, oil refineries, landscaping, greenbelts, carpet dyers, power plants, airports and the seawater barrier. The project will be the largest reclaimed water project in the United States. This paper describes the planning, design, costs and construction aspects of the reclaimed water distribution system.
