KAW CITY WWT - Kaw City, Oklahoma Wastewater Treatment Plant

KAW CITY WWT is a municipal wastewater treatment facility located in Kaw City, Kay County, Oklahoma. The plant serves a population of approximately 372 residents and operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for discharges into surface waters. The plant provides secondary treatment, a standard level for small communities in the U.S. Its designed capacity is 189.27 m³/day, with an average daily discharge volume of 151.42 m³/day, indicating operational capacity utilization. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a tributary of the Arkansas River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting local water quality and downstream ecosystems in the Great Plains region.

The plant discharges into a receiving water body within the Arkansas River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. This region supports diverse aquatic life and is important for migratory waterfowl. The secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in a semi-arid climate where water resources are critical.
