Princes Lake WWTP - Bartholomew County, Indiana Wastewater Treatment

Princes Lake WWTP is a municipal wastewater treatment facility located on Hendricks Ford Road in Bartholomew County, Indiana, United States. The plant serves a population of approximately 2,625 residents in the surrounding community. As a small-scale facility in the United States, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements. For plants serving fewer than 10,000 people, secondary treatment is typically required to meet effluent limits for biochemical oxygen demand and total suspended solids. The plant discharges treated wastewater into local streams that flow into the Driftwood River, part of the White River watershed, which ultimately drains to the Mississippi River and the Gulf of Mexico. The receiving waters support aquatic life and are used for recreation and drinking water downstream.

The plant's discharge enters local tributaries of the Driftwood River, which joins the White River in southern Indiana. The White River flows into the Wabash River, a major tributary of the Ohio River, which empties into the Mississippi River and the Gulf of Mexico. The watershed supports diverse fish populations and provides habitat for migratory birds. Downstream waters are used for municipal supply and agriculture, making nutrient and pathogen control important for ecological and human health.
