Winchester WWTP - Secondary Wastewater Treatment in Winchester, Kansas

Winchester WWTP is a municipal wastewater treatment facility located in Winchester, Kansas, serving a small population of approximately 590 residents. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for communities of this size. The plant has a designed capacity of 389.90 thousand gallons per day and currently treats an average daily flow of 223.34 thousand gallons. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, meeting the effluent limits set by its National Pollutant Discharge Elimination System (NPDES) permit issued by the Kansas Department of Health and Environment. The treated effluent is discharged to a receiving water body that ultimately drains into the Missouri River watershed, contributing to the overall water quality of the region. The plant plays a key role in protecting local streams and downstream ecosystems from untreated wastewater pollution.

The plant discharges into a local stream that flows into the Kansas River basin, part of the larger Missouri River watershed. This region supports diverse aquatic life and provides habitat for fish and migratory birds. The secondary treatment process helps reduce nutrient loads, protecting downstream water quality in the Missouri River and ultimately the Mississippi River system.
