Our Recycled Water Program

In response to increasing demands for water, limitations on imported water supplies and the threat of drought, Central Basin Municipal Water District developed a regional water recycling program. The program is comprised of two distribution systems – the E. Thornton Ibbetson Century Water Recycling Project and the Esteban Torres Rio Hondo Water Recycling Project – as well as three pumping stations and a reservoir. The Ibbetson Project and Torres Project are interconnected by an intricate 50-mile distribution system and operate as one recycled water supply system. The combined projects are referred to as the “Central Basin Water Recycling Project.”

In constructing the 50-mile pipeline system, Central Basin is able to distribute treated recycled water obtained through the Sanitation Districts of Los Angeles County. The Central Basin Water Recycling Project delivers approximately 3,100 acre-feet of recycled water annually to more than 210 industrial, commercial and landscape irrigation sites. Central Basin’s use of recycled water augments the precious groundwater and imported water supplies of southeast Los Angeles County.

Central Basin promotes recycled water as an ideal alternative for business and municipal use. As the customer base continues to expand ranging from irrigation users like golf courses and parks to unconventional commercial and industrial users new benefits of recycled water continue to be discovered. Through innovative marketing, recycled water is now being used with textiles, paper production, dye houses, co-generation plants and printing. The largest recycled water user in the Central Basin area is the Malburg Power Generation Station in the city of Vernon, using more than 1300 acre-feet annually. Metro State Hospital and Wheelabrator-Norwalk Energy Company, Inc. are also large recycled water users, with a combined annual use of 101 million gallons.
