UAT - Leo J. Vander Lans Water Treatment Facility Uses UAT RO System to Treat Recycled Wastewater
Located along the Los Angeles and Orange County border in California, the Alamitos Barrier protects a portion of the Central Basin from seawater intrusion. Through the years, over-pumping of ground water basins has caused water levels to drop and seawater to enter the basins. To prevent additional contamination, seawater intrusion barriers using potable water to source injection wells were constructed along the coastline.
The Water Replenishment District of Southern California (WRD), in partnership with the City of Long Beach and Orange County Water District, headed up the Alamitos Barrier Recycled Water Project (ABRWP) as an effort to help conserve fresh water supplies supplying over one third of water used by 4 million people in the WRD service area. The ABRWP involved the construction of a state-of-the-art water treatment facility to further purify water from the Long Beach Water Reclamation Plant. Highly treated recycled water, that otherwise would have been discarded into the
ocean, will partially substitute the potable water that was used in the Alamitos Barrier injection wells.
