The Valencia Water Reclamation Plant, a part of the Santa Clarita Valley Sanitation District, was upgraded to provide advanced treatment. It is one of two reclamation plants that discharge wastewater into the Santa Clara River, the last natural river in Southern California, which flows through Fillmore, Santa Paula, and the Oxnard Plain to the Pacific Ocean.
21 世纪初，加州地区水质控制委员会 (California Regional Water Quality Control Board) 下达指令，要求卫生局从排放到河流的废水中去除氯化物，因为他们认为氯化物对下游对盐敏感的农业会产生危害。
To meet the State’s requirements, the Sanitation District added $87.3 million in advanced treatment facilities to the Valencia Water Reclamation Plant. The advanced treatment project utilized Style W77 AGS Flexible Couplings on DIP. The AGS couplings feature a wider, wedge-shaped groove that facilitates proper coupling positioning by decreasing initial installation sensitivity. The large diameter couplings are manufactured with fusion bonded epoxy designed specifically for use on the water and wastewater systems for buried pipe.
