Montpelier WWTP - Jay County, Indiana Wastewater Treatment Plant

Montpelier WWTP is a municipal wastewater treatment facility located in Jay County, Indiana, serving a population of approximately 2,203 residents. The plant is part of the region's wastewater infrastructure, managing domestic sewage from the local community. As a US-based facility, Montpelier WWTP operates under the regulatory framework of the Clean Water Act, administered through the National Pollutant Discharge Elimination System (NPDES) permit program. For a plant serving this population size, secondary treatment is the standard requirement under federal regulations, ensuring that effluent meets water quality standards before discharge. The plant's treated effluent is discharged into a local water body that ultimately drains into the Wabash River basin, a major tributary of the Ohio River and Mississippi River system. This watershed supports diverse aquatic life and provides water resources for communities downstream.

The plant discharges into a receiving water body within the Wabash River basin, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This watershed supports a variety of fish and wildlife species and is an important ecological corridor in the Midwest. The plant's treatment performance directly affects water quality in this downstream system.
