CLAYTON PWA WWT - Clayton, Oklahoma Wastewater Treatment Plant

CLAYTON PWA WWT is a municipal wastewater treatment facility located in Clayton, Pushmataha County, Oklahoma. The plant serves a small population of 750 residents, reflecting the rural character of the area. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 416.39 m³/day and an average discharge volume of 302.83 m³/day, the facility operates below its capacity, indicating room for future growth. The plant's effluent is discharged into a local waterway, contributing to the watershed of the Kiamichi River, which flows into the Red River and ultimately the Gulf of Mexico. The plant plays a key role in protecting local water quality in the Kiamichi River basin, an ecologically diverse region supporting aquatic life and recreational activities. By treating wastewater to secondary standards, the facility helps reduce nutrient and pathogen loads, safeguarding downstream ecosystems and public health.

The plant discharges into a tributary of the Kiamichi River, which flows through southeastern Oklahoma into the Red River and then to the Gulf of Mexico. The Kiamichi River basin supports diverse aquatic habitats, including species of concern such as the Kiamichi shiner. The region's forested watershed and rural land use make the plant's treatment essential for maintaining water quality in this sensitive ecosystem.
