Rio Ramaza WWTF - Yuba City, California Wastewater Treatment Plant

Rio Ramaza WWTF is a municipal wastewater treatment facility located in Yuba City, California, within Sutter County. The plant serves a small population of 20 people and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges. The plant has a designed capacity of 7.57 million gallons per day and a discharge volume of 7.57 million gallons per day, indicating full utilization. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids before discharge. The treated effluent is discharged into the Feather River watershed, which flows into the Sacramento River and ultimately the Sacramento-San Joaquin Delta and San Francisco Bay. This region supports diverse aquatic life and is an important ecological corridor in California.

The plant discharges into the Feather River, a major tributary of the Sacramento River. The Sacramento-San Joaquin Delta is a critical estuary that supports salmon, steelhead, and other migratory fish species. The downstream environment is ecologically sensitive, with water quality regulations aimed at protecting aquatic habitats and drinking water supplies.
