Southern California relies heavily on imported water from Northern California, The Colorado River, and Owens Valley. While these water sources are limited, Southern California continues to grow. Its demand for water continues to increase. Many of the water districts in Southern California
have embarked on programs to conserve water, desalinate ocean water, and recycle brackish and treated wastewater sources. The West Basin Municipal Water District is a leader in water recycling. Its recycling facility in El Segundo, California, treats secondary effluent received from the City
of Los Angeles' Hyperion Treatment Plant to provide high quality water to satisfy irrigation demands, industrial demands and for use as seawater intrusion barrier. All of these demands would have required imported water if recycled water was not available. The West Basin Water Recycling
Facility (WBWRF), which this paper focuses on, involves the treatment of secondary wastewater effluent to produce ultra-pure water for various purposes ranging from irrigation to industrial demands. The WBWRF provides various levels of treatment. Part of its flow receives conventional direct
filtration. The balance receives membrane treatment.
