The Orange County Sanitation District (OCSD) faced complex challenges. These included addressing wastewater treatment, increasing feedwater supply and being mindful of the importance of its Groundwater Replenishment System (GWRS), which is jointly owned and operated by the Orange County Water District.
Black & Veatch was called upon to provide OCSD with preliminary and final design and construction services for a project that developed a 60 million gallons per day (mgd) activated sludge treatment train at the utility’s Plant No. 1. The $210 million construction project is the cornerstone of OCSD’s capital improvement program, one that helped the service provider achieve its goals.
“Our vision at Orange County Sanitation District for this project was two-fold. First, it was that we develop a project that would meet the requirements of our consent decree with the U.S. Environmental Protection Agency and the California State Water Resources Control Board. Second, that we provide good, clean effluent for the Groundwater Replenishment System so that we could increase the amount of reclamation that we do.”
