PENNVILLE WWTP - Advanced Wastewater Treatment in Pennville, Indiana

PENNVILLE WWTP is a municipal wastewater treatment plant located at 310 West Lagro Street in Pennville, Jay County, Indiana. Serving a population of 711, the facility provides advanced treatment to protect local water quality in this inland community. The plant employs advanced treatment processes, which exceed the secondary treatment standard required by the U.S. Clean Water Act. With a designed capacity of 605.66 megaliters and an annual discharge volume of 189.27 megaliters, the facility operates well within its capacity. As a U.S. plant, it operates under an EPA NPDES permit issued by the Indiana Department of Environmental Management, ensuring compliance with federal discharge 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 and Mississippi River system. The plant plays a key role in safeguarding the region's surface water quality and supporting downstream aquatic ecosystems.

The plant discharges into a local stream within the Wabash River watershed, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This inland location supports diverse aquatic life and is part of a larger river system that provides habitat for fish and migratory birds. The advanced treatment helps reduce nutrient loading, protecting downstream water quality in the ecologically significant Mississippi River basin.
