Drummond PWA WWT - Secondary Wastewater Treatment in Garfield County, Oklahoma

Drummond PWA WWT is a municipal wastewater treatment plant located in Garfield County, Oklahoma, serving a small population of 405 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States. The plant has a designed capacity of 264.98 megaliters and discharges approximately 189.27 megaliters of treated wastewater annually. As a US facility, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Oklahoma Department of Environmental Quality to regulate effluent quality and protect receiving waters. The treated effluent is discharged into local waterways that drain into the Arkansas River basin, eventually reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream water quality in this agriculturally intensive region of north-central Oklahoma.

The plant discharges into tributaries of the Arkansas River, which flows through Oklahoma and Arkansas before joining the Mississippi River. The downstream environment supports diverse aquatic life and is part of the Mississippi River watershed, which ultimately drains into the Gulf of Mexico. The region's agricultural land use means the plant's nutrient removal helps reduce downstream eutrophication risks.
