Montague WWTF - Advanced Wastewater Treatment in Montague, California

Montague Wastewater Treatment Facility (WWTF) is located in Montague, Siskiyou County, California, serving a population of approximately 1,456 residents. The plant provides advanced treatment, ensuring high-quality effluent before discharge. With a designed capacity of 908.50 million gallons per year and an actual discharge volume of 643.52 million gallons per year, the facility operates within its capacity. As a US plant, it falls under the Clean Water Act and is regulated via an NPDES permit issued by the California State Water Resources Control Board, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Klamath River watershed. The Klamath River flows through northern California and Oregon before reaching the Pacific Ocean, supporting diverse aquatic life including salmon and steelhead trout. The advanced treatment helps minimize nutrient and pollutant loading to this ecologically important river system.

The plant discharges into a tributary of the Klamath River, which flows through the Klamath Mountains and into the Pacific Ocean. The Klamath River is a critical habitat for anadromous fish species such as Chinook salmon and coho salmon, and supports a variety of wildlife. Advanced treatment reduces the risk of eutrophication and protects downstream water quality in this sensitive watershed.
