The Long Beach Water Reclamation Plant (WRP) is located at 7400 E. Willow Street in the City of Long Beach. The plant occupies 17 acres west of the San Gabriel River (605) Freeway. The plant initially began operation in 1973.

CURRENT OPERATION:
The Long Beach WRP provides primary, secondary and tertiary treatment for 25 million gallons of wastewater per day (see flow diagram below). The plant serves a population of approximately 250,000 people. Click on the diagram to read about the wastewater treatment and water reclamation process.

Almost 5 million gallons per day of the purified water is reused at over 40 reuse sites. Reuse includes landscape irrigation of schools, golf courses, parks, and greenbelts by the City of Long Beach, the re-pressurization of oil-bearing strata off the coast of Long Beach, and the replenishment of the Central Basin groundwater supply from water processed at the Leo J. Vander Lans Advanced Water Treatment Facility. This facility uses microfiltration, reverse osmosis, and ultraviolet disinfection to produce near distilled quality water, and is blended with imported water and pumped into the Alamitos Seawater Barrier to protect the groundwater basin from seawater contamination.
