MSD Indian Creek Drainage Basin Wastewater Treatment Plant, North Bend, Ohio

MSD Indian Creek Drainage Basin is a municipal wastewater treatment plant located on Harbor Avenue in North Bend, Ohio, serving a population of approximately 3,393 residents. The facility is part of the Metropolitan Sewer District of Greater Cincinnati's infrastructure, managing wastewater from the Indian Creek drainage basin in Hamilton County. As a small-scale plant in the United States, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits and monitoring requirements. The plant's treated effluent ultimately drains into the Ohio River via Indian Creek, contributing to the river's water quality management. The Ohio River is a major tributary of the Mississippi River, supporting diverse aquatic life and providing drinking water for millions downstream. The plant's location in a suburban area near the river underscores its role in protecting local water resources.

The plant discharges into Indian Creek, a tributary of the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River watershed supports a variety of fish species and is an important migratory corridor for birds. The plant's operations help maintain water quality in this ecologically significant river system, particularly given the proximity to suburban development and agricultural areas in southwestern Ohio.
