ACHILLE PUA WWT - Secondary Wastewater Treatment Plant in Achille, Oklahoma

ACHILLE PUA WWT is a municipal wastewater treatment facility located on South 2nd Avenue in Achille, Bryan County, Oklahoma. Serving a population of approximately 525 residents, the plant provides secondary treatment to meet Clean Water Act standards. The facility has a designed capacity of 264.98 m³/day and currently treats 189.27 m³/day of wastewater. As a secondary treatment plant, ACHILLE PUA WWT uses biological processes to reduce organic matter and suspended solids. The plant operates under the US EPA National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Oklahoma Department of Environmental Quality. These permits set effluent limits to protect water quality in the receiving water body. The treated effluent is discharged into a local waterway that eventually drains into the Red River basin. The Red River flows through Oklahoma, Texas, Arkansas, and Louisiana before emptying into the Mississippi River and ultimately the Gulf of Mexico. The plant's operations help maintain water quality in this important regional watershed.

The plant discharges into a tributary of the Red River, which flows through the southern Great Plains into the Mississippi River and Gulf of Mexico. The Red River basin supports diverse aquatic life and provides water for agriculture and communities downstream. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting the ecological health of the river system.
