Austin WWTF - Secondary Wastewater Treatment Plant in Austin, Nevada

Austin WWTF is a municipal wastewater treatment facility located in Austin, Lander County, Nevada, United States. The plant serves a small population of 500 residents, reflecting the rural character of the area. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment as the minimum standard for municipal wastewater plants. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 170.34 million gallons per day and an actual discharge volume of 56.78 million gallons per day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The plant's discharge is managed through a National Pollutant Discharge Elimination System (NPDES) permit, which sets limits on effluent quality to protect receiving waters. The treated effluent from Austin WWTF is discharged into a local water body that ultimately drains into the Humboldt River basin, a major watershed in northern Nevada. The Humboldt River flows through arid high desert terrain and terminates in the Humboldt Sink, an endorheic basin. The plant's discharge contributes to the river's flow, supporting aquatic life and downstream water users in this water-scarce region.

The plant's discharge enters a tributary of the Humboldt River, which flows through the Great Basin desert and ends in the Humboldt Sink. This watershed supports a variety of adapted species, including the Lahontan cutthroat trout in upper reaches. The arid climate means that even small discharges can have significant ecological impacts, maintaining base flows and water quality in a region where water is a limiting resource.
