CHRISNEY WWTP - Advanced Wastewater Treatment in Chrisney, Indiana

CHRISNEY WWTP is a municipal wastewater treatment facility located in Chrisney, Indiana, serving a small population of 544 residents. The plant is situated in Spencer County, a rural area in the southwestern part of the state, and operates as part of the local infrastructure to manage domestic wastewater. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional nutrients and contaminants. With a designed capacity of 264.98 cubic meters per day and a discharge volume of 189.27 cubic meters per day, the facility operates well within its capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent is discharged into a local receiving water body, likely a tributary of the Ohio River, which ultimately flows into the Mississippi River and the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient loading, which is critical for preventing downstream eutrophication and maintaining the ecological health of the Mississippi River Basin.

The plant discharges into a local waterway that drains into the Ohio River, a major tributary of the Mississippi River. The Mississippi River Basin supports diverse aquatic life and is an important migratory corridor for fish and birds. Advanced treatment at this plant helps minimize nutrient pollution, which is a key concern for the Gulf of Mexico's hypoxic zone.
