Kremlin WWT is a municipal wastewater treatment facility located in Kremlin, Oklahoma, a small town in Garfield County. The plant serves a population of approximately 240 residents, reflecting its role in a rural community. The plant provides secondary treatment, a standard level required by the U.S. Clean Water Act for most municipal facilities. Its designed capacity is 124.92 megaliters, with an actual discharge volume of 75.71 megaliters, indicating operational headroom. As a U.S. facility, it operates under an EPA NPDES permit issued by the Oklahoma Department of Environmental Quality, ensuring compliance with effluent limits. The treated effluent is discharged into a local waterway that drains into the Arkansas River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant's operation helps protect local streams and downstream aquatic ecosystems from untreated wastewater.

The plant discharges into a tributary of the Arkansas River, which flows through Oklahoma and Arkansas before joining the Mississippi River. This watershed supports diverse aquatic life and provides water for agriculture and recreation. The secondary treatment process reduces organic pollutants and suspended solids, helping maintain water quality in the downstream river system.
