New Castle WWTP is a municipal wastewater treatment facility located on River Road in Henry County, Indiana, serving a population of about 21,254. The plant is situated inland, away from coastal areas, and discharges treated effluent into local waterways that ultimately drain to the Ohio River basin. As a medium-sized agglomeration, the plant is subject to U.S. EPA National Pollutant Discharge Elimination System (NPDES) permitting requirements under the Clean Water Act. These permits set effluent limits based on the receiving water's assimilative capacity and technology-based standards. The plant's treated wastewater enters the local watershed, which flows into the White River and then the Wabash River, a major tributary of the Ohio River. The Ohio River supports diverse aquatic life and provides drinking water for millions downstream. The plant's discharge quality is critical for maintaining the ecological health of these river systems.
