Uniondale WWTP - Secondary Treatment Plant in Uniondale, Indiana

Uniondale WWTP is a municipal wastewater treatment facility located in Uniondale, Wells County, Indiana. The plant serves a small population of 277 residents, reflecting its role in a rural community. It is situated at 5360 North 100 West, within the agricultural landscape of northeastern Indiana. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. Its designed capacity is 83.28 million gallons per year, matching the reported discharge volume. As a small facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Indiana Department of Environmental Management, ensuring compliance with effluent limits. The treated effluent is discharged into a local waterway that ultimately drains into the Wabash River basin, a major tributary of the Ohio River. The Wabash River supports diverse aquatic life and is an important ecological corridor in the Midwest. The plant's discharge contributes to the overall water quality management in the region.

Uniondale WWTP discharges into a receiving water body within the Wabash River basin. The Wabash River flows southwest through Indiana, joining the Ohio River near the state's southern border. This watershed supports a variety of fish and macroinvertebrate species, and the plant's secondary treatment helps protect downstream water quality. The surrounding area is primarily agricultural, so the plant plays a role in managing nutrient loads that could otherwise impact the river ecosystem.
