Sewerage Commis Oroville Reg WWTP - Oroville, California Wastewater Treatment

Sewerage Commis Oroville Reg WWTP is a municipal wastewater treatment facility located in Oroville, Butte County, California. It serves a population of approximately 39,101 residents, making it a medium-sized agglomeration under US regulatory standards. The plant is situated inland, away from coastal areas, and its operations are integral to the local water infrastructure. As a US facility, the plant is subject to the Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the California State Water Resources Control Board or a regional board. For a plant serving this population size, secondary treatment is typically required, with possible additional nutrient removal if discharging to sensitive waters. The regulatory framework ensures compliance with effluent limits. The plant discharges treated wastewater into a local water body, likely a tributary of the Feather River, which flows into the Sacramento River and ultimately to the San Francisco Bay and the Pacific Ocean. The facility plays a key role in protecting downstream water quality and aquatic habitats in the Sacramento River basin.

The plant's treated effluent likely enters a tributary of the Feather River, which flows into the Sacramento River and then into the San Francisco Bay estuary. This watershed supports diverse aquatic life, including salmon and steelhead trout, and is an important ecological corridor. The plant's discharge must meet strict water quality standards to protect these downstream ecosystems.
