TONKAWA MA WWT Wastewater Treatment Plant, Kay County, Oklahoma

TONKAWA MA WWT is a municipal wastewater treatment facility located in Kay County, Oklahoma, serving a population of about 3,300. The plant is situated in the north-central part of the state, an area characterized by rolling plains and agricultural activity. As a small-scale facility, it plays a key role in managing local wastewater for the community. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal wastewater. Facilities of this size typically employ biological treatment processes such as activated sludge or lagoon systems, and are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Oklahoma Department of Environmental Quality. The treated effluent from TONKAWA MA WWT is discharged to a local waterway that ultimately drains into the Arkansas River basin, a major tributary of the Mississippi River. This connection underscores the plant's role in protecting downstream water quality and the broader ecological health of the Mississippi River system.

The plant discharges to a local stream 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 part of an important migratory corridor for birds. Proper treatment helps reduce nutrient loading and protects downstream ecosystems from eutrophication.
