McDermitt STP - Secondary Wastewater Treatment in Fort McDermitt, Nevada

McDermitt STP is a wastewater treatment facility located in Fort McDermitt, Nevada, within Humboldt County. The plant serves a small community of approximately 1,320 residents, providing essential sanitation services in this rural area of the western United States. The plant operates at the secondary treatment level, which is the standard required by the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 567.81 volume units and a current discharge volume of 492.10, the plant is operating below its capacity, indicating room for future growth. As a facility in the United States, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Nevada Division of Environmental Protection, ensuring compliance with federal water quality standards. The treated effluent from McDermitt STP is discharged into the local watershed, which ultimately drains into the Quinn River system. This river flows through the Great Basin region, a closed basin that does not reach the ocean, making water quality management critical for local ecosystems. The plant plays a key role in protecting the Quinn River and its associated wetlands from nutrient pollution and pathogens, supporting aquatic life and downstream water users.

McDermitt STP discharges into the Quinn River watershed, part of the Great Basin's closed drainage system. The Quinn River flows into the Quinn River Sink, a terminal playa lake, where water evaporates and salts accumulate. This sensitive environment requires careful management of nutrient and pathogen loads to prevent eutrophication and protect migratory bird habitats that rely on these desert wetlands.
