Gerlach GID Wastewater Treatment Plant, Gerlach, Nevada

Gerlach GID is a municipal wastewater treatment facility located in Gerlach, Washoe County, Nevada, United States. The plant serves a small population of 482 residents, reflecting the rural character of this remote desert community in the Great Basin region. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. It has a designed capacity of 98.42 units and currently discharges 53.00 units of treated effluent, indicating operational headroom. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Nevada Division of Environmental Protection, ensuring compliance with federal water quality standards. The treated effluent is discharged into the local watershed, which is part of the Great Basin's internal drainage system. This arid region lacks outflow to the ocean, making groundwater recharge and local water quality particularly important for sustaining the fragile desert ecosystem and the community's water supply.

The plant discharges into the Great Basin, a vast endorheic basin that does not drain to any ocean. The local watershed includes ephemeral streams and playa lakes, such as the nearby Smoke Creek Desert and Black Rock Desert. These water bodies support unique desert-adapted species and are ecologically sensitive to nutrient loading and contaminants from wastewater discharges.
