Winslow WWTP - Secondary Treatment Plant in Winslow, Indiana

Winslow WWTP is a municipal wastewater treatment facility located on SR 61 in Winslow, Pike County, Indiana. It serves a small community of around 1,100 people, reflecting its role as a local infrastructure asset for this rural area in the Midwestern United States. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 340.69 million gallons per day, the facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Indiana Department of Environmental Management. This regulatory framework ensures that effluent meets water quality standards to protect receiving waters. The treated effluent from Winslow WWTP discharges into nearby streams that are part of the Mississippi River basin. These waters eventually flow into the Gulf of Mexico, contributing to the overall health of the downstream aquatic ecosystem. The plant's operation helps maintain local water quality and supports the ecological balance of the region's waterways.

The Winslow WWTP discharges into local tributaries of the Mississippi River basin, which ultimately drain into the Gulf of Mexico. This watershed supports diverse aquatic life and provides habitat for fish and other organisms.
