Chief Plant Operator


The Wastewater Treatment Plant Division operates and maintains the city’s wastewater treatment facilities (WWTF). The WWTF consists of a domestic plant (6.0 million gallons per day (MGD) capacity) and an industrial plant (12.0 MGD capacity) treating about 3.5 MGD in the domestic plant and about 8.5 MGD in the industrial plant.  This includes operation, maintenance and repair of treatment structures, such as lift stations, sedimentation tanks, digesters, filters, pumps and control buildings.  Additional operations include 320 acres of storage ponds, 2,200 acres of farmland under permit for beneficial reuse of treated wastewater, and self-generation of renewable energy including the anaerobic bulk volume fermenter, 1.2 MW of fuel cells, and 1.0 MW of solar photovoltaic panels.  This division is also responsible for performing laboratory analyses on domestic and industrial waste samples as well as domestic water samples. It is very important that treatment of wastewater be carefully controlled and the equipment maintained to insure compliance with the discharge requirements set by the State Regional Water Quality Control Board. The Wastewater Divisions operate under the direction of the Board of Public Utilities.
