| Objectives | The Discharger owns and operates a wastewater collection, treatment, and disposal system, and
provides sewage service to the City of Oroville, Thermalito Irrigation District, Lake Oroville
Area Public Utility District, State of California Parks and Recreation Department, and State of
California Department of Water Resources (DWR) as a regional treatment plant. The
Dischargers responsibility for the collection system ends at the termination of its east and west
interceptors, which consist of approximately 3.25 miles of pipe line and 2 pump stations (Rudy
Creek and Feather River). An average dry weather flow of 3.2 million gallons per day (mgd)
of treated domestic and industrial wastewater is discharged to the Feather River
(Discharge 001), a water of the United States. The treatment system consists of screening for removal of large solids, grit removal, primary
clarification, activated sludge treatment with secondary clarification, filtration, chlorination,
and dechlorination. Sludge is aerobically treated, dried on site, and then disposed at a sanitary
landfill. |
