Glencoe NW WWT - Secondary Wastewater Treatment Plant in Glencoe, Oklahoma

Glencoe NW WWT is a municipal wastewater treatment facility located in Glencoe, Oklahoma, serving a small population of 583 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges to surface waters. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 276.33 million gallons per year and an actual discharge volume of 151.42 million gallons per year, the facility operates below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local waterway that ultimately drains into the Arkansas River basin, contributing to the Mississippi River watershed. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in the region.

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 plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in the Arkansas River basin.
