Geyserville WWTF - Advanced Wastewater Treatment in Geyserville, California

Geyserville WWTF is an advanced wastewater treatment facility located in Geyserville, Sonoma County, California. It serves a small population of 809 residents, reflecting the rural character of the area. The plant is situated near River Road and operates as part of the local municipal infrastructure. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 348.26 units and a discharge volume of 234.70 units, it operates below its capacity. Under the US Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Russian River watershed and then to the Pacific Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems, including sensitive habitats in the Russian River estuary and coastal zone.

The plant discharges into a tributary of the Russian River, which flows through Sonoma County before reaching the Pacific Ocean at Jenner. The Russian River watershed supports diverse aquatic life, including steelhead trout and Chinook salmon. Advanced treatment at this plant reduces nutrient loading, helping to maintain water quality in this ecologically important coastal river system.
