PERC Water currently operates the Water Replenishment District’s (WRD) Leo J. Vander Lans Advanced Water Treatment Facility (LVL AWTF). This facility produces 8 million gallons per day (mgd) of advanced treated water and includes a three-stage treatment process consisting of Microfiltration, Reverse Osmosis (RO) and Disinfection with Advanced Oxidation.

WRD’s Leo J. Vander Lans Advanced Water Treatment Facility (LVL) was built in 2003 and expaded in 2014. Located in the City of Long Beach, this facility provides advanced treated water to the Alamitos Barrier, playing a vital role in the Central Groundwater Basin. LVL receives Title 22 (tertiary treated recycled water) from the adjacent Los Angeles County Sanitation District’s Long Beach Water Reclamation Plant. In addition, this water replenishes the groundwater supply.

The Seawater Barrier’s, which are owned and operated by the Los Angeles County Department of Public Works, have been successfully protecting and supplying the fresh water aquifers in the WRD service area for decades. WRD also works closely with the Orange County Water District to ensure that the water demands at the barrier are fulfilled through the use of recycled water as opposed to imported water.
