Alamitos Barrier Recycled Water Project
Leo J. Vander Lans Water Treatment Facility

Butier Engineering, Inc. served as Construction Manager for the Water Replenishment District of Southern California's Alamitos Barrier Recycled Water Project. The project is a state-of-the-art water treatment facility built to ensure that Southern California's groundwater supply is sufficient, clean, and safe. The facility supplies water to protect the Central Groundwater Basin from seawater contamination and ultimately to protect the drinking water for the region. Once treated, the water is blended with imported potable water and pumped into the Alamitos Seawater Barrier.

The project was undertaken cooperatively with the City of Long Beach. Tertiary effluent from the Long Beach Water Reclamation Plant, already treated to Title 22 non-potable reuse standards, is taken and treated to the standards required for injection into the Alamitos Barrier using microfiltration, reverse osmosis, and ultra violet (UV) radiation treatment.

The project is located on four acres of land approximately two miles inland from the Pacific Ocean in the City of Long Beach, between the Long Beach Water Reclamation Plant and undeveloped land owned by the City of Long Beach.
