OKARCHE WWT Wastewater Treatment Plant, Okarche, Oklahoma

OKARCHE WWT is a municipal wastewater treatment plant located in Okarche, Oklahoma, United States. The facility serves a population of approximately 1,110 residents and operates as part of the town's public infrastructure. It is situated in Kingfisher County, a rural area in the central part of the state. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. The designed capacity is 529.96 m³/day, and the current discharge volume is 378.54 m³/day, indicating the plant operates below its full capacity. As a U.S. facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Oklahoma Department of Environmental Quality, ensuring compliance with effluent limits. The treated effluent is discharged into a local waterway, likely a tributary of the North Canadian River, which flows into the Arkansas River and eventually the Mississippi River. This drainage system supports regional aquatic habitats and agricultural water use. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall water quality of the river basin.

The treated effluent from OKARCHE WWT enters a local stream that drains into the North Canadian River, part of the Arkansas-White-Red River basin. This watershed supports diverse aquatic life and provides water for irrigation and recreation downstream. The plant's secondary treatment helps protect the river ecosystem from nutrient pollution and organic matter, though advanced treatment could further reduce environmental impact.
