WELEETKA PWA WWT - Okmulgee, Oklahoma Wastewater Treatment Plant

WELEETKA PWA WWT is a municipal wastewater treatment plant located in Okmulgee, Oklahoma, serving a population of 1,014. The facility provides secondary treatment, a standard level for small communities in the United States, and operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for all discharges. The plant has a designed capacity of 545.10 units and currently treats an average daily flow of 454.25 units. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, meeting the effluent standards set by the US Environmental Protection Agency for small agglomerations. The treated effluent is discharged into a local water body, likely a tributary of the Arkansas River system, which flows through Oklahoma and eventually into the Mississippi River. This discharge supports downstream aquatic life and water quality, with the plant playing a key role in protecting the regional watershed from untreated wastewater.

The plant discharges into a local water body within the Arkansas River basin, which drains into the Mississippi River and ultimately the Gulf of Mexico. The receiving waters support diverse aquatic life and are part of a larger watershed that provides drinking water and recreation. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream ecosystems from eutrophication and oxygen depletion.
