OAKLEY WWTP - Logan County, Kansas Wastewater Treatment Plant

OAKLEY WWTP is a municipal wastewater treatment facility located in Logan County, Kansas, serving a population of approximately 2,045 residents. The plant provides secondary treatment, a standard level for communities of this size under the US Clean Water Act. The plant has a designed capacity of 863.07 thousand cubic meters and reports an annual discharge volume of 776.01 thousand cubic meters. As a facility in the Great Plains region, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Kansas River basin and then the Missouri River system. This watershed supports agricultural irrigation and provides habitat for native fish and wildlife species common to the central Great Plains.

The plant's discharge enters the Smoky Hill River watershed, which flows eastward to the Kansas River and eventually the Missouri River. This region is part of the central Great Plains, characterized by semi-arid climate and intensive agriculture. The receiving waters support aquatic life adapted to prairie streams, including various minnow and sucker species, and are important for regional water supply.
