RINGWOOD WWT Wastewater Treatment Plant, Ringwood, Oklahoma

RINGWOOD WWT is a municipal wastewater treatment facility located in Ringwood, Major County, Oklahoma, United States. The plant serves a small population of 424 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 211.98 m³/day and currently treats an average of 189.27 m³/day, operating below its capacity. Under the U.S. Clean Water Act, secondary treatment is the minimum standard for municipal wastewater, and plants of this scale typically operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Oklahoma Department of Environmental Quality. 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's operation helps protect local water quality and downstream ecosystems in the Great Plains region.

The plant discharges into a local stream within the Arkansas River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The surrounding region is part of the Great Plains, characterized by agricultural land use and intermittent streams. The plant's secondary treatment helps reduce nutrient and organic loads, supporting aquatic life in downstream waters and preventing eutrophication in receiving water bodies.
