Overview
Reno City of TMWRF is a major wastewater treatment plant serving approximately 288,000 people in Washoe County, Nevada. It operates under the US Clean Water Act's NPDES permit program.
Reno City of TMWRF (Truckee Meadows Water Reclamation Facility) is a large municipal wastewater treatment plant located in Washoe County, Nevada, serving the Reno-Sparks metropolitan area. With a population served of 288,000, it is classified as a large agglomeration under US regulatory standards. The plant operates under the US Clean Water Act, which requires NPDES permits for all discharges into surface waters. For facilities of this scale, secondary treatment is the minimum standard, though many plants in arid regions like Nevada employ advanced treatment for water reuse. Typical facilities of this size use activated sludge or similar biological processes. The plant's treated effluent is discharged into the Truckee River, which flows from Lake Tahoe through Reno to Pyramid Lake, an endorheic desert lake. This watershed is ecologically sensitive, supporting diverse aquatic life and providing critical habitat for migratory birds in the Great Basin. The plant plays a key role in protecting water quality in this arid region.
Environmental context
The plant discharges into the Truckee River, which originates from Lake Tahoe and flows northeast through Nevada to Pyramid Lake, a terminal desert lake. This watershed is ecologically sensitive, supporting species such as the Lahontan cutthroat trout and providing critical habitat for migratory waterfowl. The arid climate and water scarcity make wastewater treatment and potential reuse essential for maintaining downstream ecosystem health and regional water supply.
