Expansion of the existing 10.5 MGD water treatment facility to 21.0 MGD. Improvements included construction of two circular clarifier units, two gravity filters, waste wash-water recovery basin, raw water structure, operations building, chemical building, division berm and connection piping of two existing 25 MG earthen storage reservoirs, clearwell and backwash water recovery pump stations, and associated site improvements including site piping, grading, paving, and electrical instrumentation and controls. Full service was maintained at the existing plant while all capital improvements were completed on this complex, multiple staged construction project.
