Roscoe WWTP - Secondary Wastewater Treatment in Roscoe, Texas

Roscoe WWTP is a municipal wastewater treatment facility located in Roscoe, Nolan County, Texas. The plant serves a population of approximately 1,300 residents, reflecting its role as a small-scale community infrastructure asset in the semi-arid region of West Texas. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 567.81 megaliters and an annual discharge volume of 454.25 megaliters, the plant operates within its capacity. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Texas Commission on Environmental Quality, which sets effluent limits to protect receiving water quality. The treated effluent is discharged into local waterways that ultimately drain into the Brazos River basin, a major river system in Texas. The plant's operations help protect downstream aquatic ecosystems and support water quality in the region, which is characterized by agricultural land use and periodic drought conditions.

The plant discharges into local tributaries that flow into the Brazos River, which empties into the Gulf of Mexico. The Brazos River basin supports diverse aquatic life and is an important water resource for agriculture and communities in central Texas. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, mitigating impacts on downstream water quality and the coastal environment.
