New Market WWTP - North Union, Indiana Wastewater Treatment Plant

New Market WWTP is a municipal wastewater treatment facility located in North Union, Montgomery County, Indiana, United States. It serves a small community of 659 people, reflecting its role in rural wastewater management within the state. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 261.19 volume units and a discharge volume of 261.19, the facility operates at full capacity. Under the US Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Wabash River basin, ultimately reaching the Ohio River and then the Mississippi River. This downstream connection underscores the plant's role in protecting regional water quality and aquatic ecosystems.

The plant discharges into streams within the Wabash River watershed, which flows into the Ohio River and then the Mississippi River. This drainage system supports diverse aquatic life and provides habitat for fish and migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the ecological health of the downstream rivers and the Gulf of Mexico.
