GARBERVILLE WWTF - Secondary Treatment Plant in Briceland, California

GARBERVILLE WWTF is a municipal wastewater treatment facility located in Briceland, Humboldt County, California. Serving a population of approximately 1,300, the plant provides secondary treatment to wastewater from the local community. Its designed capacity is 567.81 megaliters, with an annual discharge volume of 151.42 megaliters, indicating moderate utilization. The plant is situated inland, more than 10 kilometers from the Pacific coast, within the Eel River basin. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. Secondary treatment is the minimum standard for municipal plants, ensuring removal of organic matter and suspended solids. The treated effluent likely discharges to a local waterway that drains into the Eel River, which flows to the Pacific Ocean. The plant's operation supports water quality in the region, protecting downstream aquatic habitats and recreational uses.

The plant's discharge enters a tributary of the Eel River, a major coastal watershed in Northern California. The Eel River supports diverse aquatic life, including salmon and steelhead trout, and drains into the Pacific Ocean near Humboldt Bay. The region's Mediterranean climate with seasonal rainfall influences flow patterns, making consistent treatment critical for maintaining ecological health during low-flow summer months.
