Xylem, a global water technology company dedicated to solving the world’s most challenging water issues, has been awarded a contract to provide advanced filtration technology to the Metropolitan Water District of Southern California’s F.E. Weymouth Water Treatment Plant in La Verne, Calif., as part of a project to retrofit the plant with biologically active filtration and ozone.
Xylem will supply its Leopold Type XA underdrains with I.M.S 200 media retainers and Leopold dual media sand and anthracite to the plant, which treats water from the Colorado River Aqueduct and the State Project Water (SPW) California Aqueduct.
Jim Kostelecky, Weymouth Plant manager, said, “The plant was placed in service in 1941, initially with mono-media filters and a clay tile underdrain. As the plant was expanded concrete tee-pee underdrains were installed and all of the filters were converted to dual media filters. The Xylem Leopold Type XA underdrains provided us with an opportunity to remove the old underdrains and support gravel and install substantially deeper layers of sand and anthracite, without a significant impact to the plant’s existing hydraulic profile. Based on previously conducted full scale testing it is anticipated that the new retrofit filters will provide a far more robust filtration process, which will be in service for another 75 years or more.”
Matt Schomaker, technical sales manager for Xylem Leopold products in North America, said, “Our application knowledge and experience as well as our filter media application and processing expertise were key factors in securing this contract. A highly specialized media specification was desired by the Metropolitan Water District to enhance filtration performance.”
Construction on the plant is already underway and phase 1 of the new system is due to be operational in Q1 2016.
