Poneto Municipal STP - Wellsburg, Indiana Wastewater Treatment Plant

Poneto Municipal STP is a wastewater treatment facility located on South Meridian Road in Wellsburg, Wells County, Indiana. It serves a small population of 166 residents, reflecting its role as a local municipal plant in a rural area of the Midwestern United States. The plant provides secondary treatment, a standard level required by the US Clean Water Act for municipal wastewater. Its designed capacity and discharge volume are both 90.85 units, indicating consistent operation. As a small facility, it likely operates under an Indiana Department of Environmental Management (IDEM) NPDES permit, which sets effluent limits to protect water quality. The treated effluent from Poneto Municipal STP discharges into a local waterway that ultimately drains into the Wabash River basin, a major tributary of the Ohio River and Mississippi River system. This downstream connection underscores the plant's role in safeguarding regional water quality and aquatic habitats.

The plant discharges into a local stream that flows into the Wabash River, a major tributary of the Ohio River. The Wabash River supports diverse aquatic life and is an important ecological corridor in the Midwest. Downstream, the Ohio River feeds into the Mississippi River, eventually reaching the Gulf of Mexico. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting these downstream waters from eutrophication and other impacts.
