Lefors WWTP is a municipal wastewater treatment facility located in Gray County, Texas, serving a small population of around 500 residents. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for most municipal facilities to protect water quality. The plant's designed capacity is 181.70 megaliters, and it currently treats an annual discharge volume of 94.64 megaliters, indicating operational headroom. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to safeguard receiving waters. The treated effluent is discharged into local waterways that drain into the Red River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting the region's surface water quality and supporting downstream aquatic ecosystems.

The plant discharges into the Red River basin, which flows through Texas and Oklahoma before joining the Mississippi River and emptying into the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this semi-arid region.
