Russian River County WWTF - Edendale, California Wastewater Treatment Plant

Russian River County WWTF is a municipal wastewater treatment facility located on Neeley Road in Edendale, Sonoma County, California. The plant serves a population of approximately 7,377 residents and has a designed capacity of 1.00 million gallons per day. As a small to medium-sized facility, it plays a key role in managing wastewater for the local community. The plant operates under the regulatory framework of the U.S. Clean Water Act, administered by the California State Water Resources Control Board and the San Francisco Bay Regional Water Quality Control Board. Facilities of this scale typically require secondary treatment as a minimum standard, with possible additional nutrient removal depending on the sensitivity of the receiving water body. Compliance with state and federal permits is expected. The treated effluent from the plant is discharged into the Russian River watershed, which flows through Sonoma County and eventually drains into the Pacific Ocean via the Russian River estuary. The river supports diverse aquatic life, including salmon and steelhead trout, and is an important ecological corridor in the region. The plant's proximity to the coast (within 50 km) underscores the importance of effective treatment to protect downstream water quality and marine habitats.

The Russian River watershed drains through Sonoma County into the Pacific Ocean, supporting a diverse ecosystem that includes anadromous fish species such as coho salmon and steelhead trout. The river's estuary provides critical habitat for migratory birds and marine life. The plant's discharge contributes to the river's flow, and its treatment performance is essential for maintaining water quality in this ecologically sensitive coastal watershed.
