TUPELO WWT Wastewater Treatment Plant, Tupelo, Oklahoma

TUPELO WWT is a municipal wastewater treatment facility located in Tupelo, Oklahoma, serving a small population of 388 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States, ensuring compliance with federal and state water quality standards. The plant has a designed capacity of 189.27 megaliters and discharges approximately 151.42 megaliters of treated effluent annually. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect receiving water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated wastewater is discharged into local waterways that ultimately drain into the Red River basin, contributing to the Mississippi River watershed. This region supports diverse aquatic life and is important for regional water resources. The plant's operations help maintain water quality in downstream ecosystems.

The plant discharges into local streams that flow into the Red River, a major tributary of the Mississippi River. The Red River basin supports diverse aquatic habitats and is ecologically significant for migratory fish and waterfowl. Downstream waters eventually reach the Gulf of Mexico, where nutrient management is critical to prevent hypoxic zones.
