Severn Trent Services has been awarded a contract to supply its UAT line of reverse osmosis (RO) membrane products for the Alamitos Barrier Recycled Water Project Advanced Water Treatment Facility (ABRWP). Severn Trent's products support the effort to conserve fresh water supplies and improve the quality of the three million gallons of water supplied to the Alamitos Barrier injection wells each day.
The Water Replenishment District of Southern California (WRD), in partnership with the City of Long Beach and Orange County Water District, is heading up the project. The ABRWP involves the construction of a state-of-the-art water treatment facility to further purify water from the Long Beach Water Reclamation Plant. The highly treated recycled water, which otherwise would be discarded into the ocean, will be substituted for potable water currently used in the Alamitos Barrier injection wells.
Located along the Los Angeles and Orange County border, the Alamitos Barrier protects a portion of the Central basin from seawater intrusion. Through the years, the over-pumping of groundwater basins caused water levels to drop and seawater to enter the basins. To prevent additional contamination, seawater intrusion barriers with injection wells were constructed along the coastline.
As part of the complete filtration package designed by Separation Process, Inc., Severn Trent will provide one UAT unit train consisting of 756 membranes with 108 pressure vessels.
"The WRD is pleased to work with Severn Trent on this important project which will help ensure a reliable and cost-effective supply of water for the Alamitos Barrier while having a positive impact on the environment," WRD Project Manager Melinda Sperry said.
