Document Description
The Malibu Mesa Water Reclamation Plant Refurbishment (Proposed Project) includes installation of temporary filters, demolition of existing filter equipment, installation of a Parshall flume, pump station with diversion structure, fine screens, anoxic/aerobic bioreactors, membrane tanks, and permeate pumps; membrane thickening tank, new UV system, installation of new structural members in the existing building to support new electrical equipment; installation of a new standby generator, new process equipment and pump replacement; demolition of the existing generator and fuel tank; refurbishment of the existing round activated sludge process structure, refurbishment of the existing building; relocation of Southern California Edison equipment; and a paved parking area. The Proposed Project would not increase the treatment capacity. The Proposed Project would provide adequate treatment with two treatment trains to comply with all water recycling and discharge limits. During construction, a temporary filtration unit would be required to maintain continuous operation. The Proposed Project is located at the existing Malibu Mesa Water Reclamation Plant. The Malibu Mesa Water Reclamation Plant is located at 3863 Malibu Country Drive, Malibu, CA 90265 and generally located on the northwest corner of Pacific Coast Highway and John Tyler Drive in the City of Malibu, California (APN: 4458041900).
