KINGMAN WWTP - Advanced Wastewater Treatment in Kingman, Indiana

KINGMAN WWTP is a municipal wastewater treatment plant located in Kingman, Indiana, a small community in Fountain County. The facility serves a population of approximately 565 residents, classifying it as a small-scale treatment operation within the state's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. It has a designed capacity of 264.98 thousand cubic meters per year, with a corresponding discharge volume matching that capacity. As a U.S. facility, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into a local receiving water body, likely a tributary of the Wabash River, which flows into the Ohio River and ultimately the Mississippi River. This downstream connection highlights the plant's role in protecting regional water quality and aquatic ecosystems in the Mississippi River Basin.

The plant discharges into a local waterway that drains into the Wabash River, a major tributary of the Ohio River. The Ohio River flows into the Mississippi River, which empties into the Gulf of Mexico. This watershed supports diverse aquatic life and provides habitat for fish and migratory birds. The advanced treatment helps reduce nutrient loading, which is critical for preventing downstream hypoxia in the Gulf of Mexico.
