Boswell WWT - Secondary Wastewater Treatment Plant in Boswell, Oklahoma

Boswell WWT is a municipal wastewater treatment facility located in Boswell, Choctaw County, Oklahoma. The plant serves a small population of around 710 residents, providing essential sanitation services for this rural community in the southeastern part of the state. The plant employs secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 246.05 thousand gallons per day and a current discharge volume of 189.27 thousand gallons per day, the facility operates below its capacity, indicating room for future growth. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Oklahoma Department of Environmental Quality, ensuring compliance with federal water quality standards. The treated effluent from Boswell WWT is discharged into local streams that eventually flow into the Red River, which forms the border between Oklahoma and Texas. The Red River drains into the Mississippi River and ultimately the Gulf of Mexico. The plant's operations help protect the water quality of these downstream water bodies, supporting aquatic life and recreational uses in the region.

Boswell WWT discharges into tributaries of the Red River, which flows southward through Oklahoma and Texas before joining the Mississippi River and emptying into the Gulf of Mexico. The Red River basin supports diverse aquatic ecosystems and is an important migratory corridor for birds. The plant's secondary treatment helps reduce nutrient loads and organic pollutants, mitigating the risk of eutrophication in downstream waters.
