DWIGHT WWTP - Morris County, Kansas Wastewater Treatment Plant

DWIGHT WWTP is a municipal wastewater treatment plant located in Morris County, Kansas, serving a small population of 331 residents. The facility provides secondary treatment, which is the standard level required by the US Clean Water Act for most inland plants of this scale. The plant has a designed capacity of 264.98 million gallons per year and currently discharges 124.92 million gallons annually. As a small agglomeration, 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 within the Kansas River basin, which ultimately drains to the Missouri River and then the Mississippi River. The plant plays a role in protecting downstream aquatic ecosystems and maintaining water quality in the region.

The plant discharges into receiving waters within the Kansas River watershed, which flows into the Missouri River and eventually the Mississippi River. This region supports diverse aquatic life and is part of a major migratory corridor for birds. The secondary treatment process helps reduce organic pollutants and suspended solids, protecting downstream habitats.
