Berkshire Pointe HCRWD WWTP - Harrison County, Indiana Wastewater Treatment Plant

Berkshire Pointe HCRWD WWTP is a municipal wastewater treatment facility located in Harrison County, Indiana, United States. The plant serves a small population of 132 residents, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. As a secondary treatment plant, it meets the minimum requirements under the U.S. Clean Water Act for municipal wastewater treatment. The plant has a designed capacity of 113.56 volume units and treats a similar daily flow, indicating full utilization. It operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into local streams that drain into the Ohio River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant's location inland and away from coastal areas reduces direct marine impact, but its discharge contributes to the overall nutrient and pollutant load in the Mississippi River basin, which affects the Gulf of Mexico's hypoxic zone.

The plant discharges into small streams in Harrison County, which flow into the Blue River and then the Ohio River. The Ohio River is a major tributary of the Mississippi River, which empties into the Gulf of Mexico. The Gulf of Mexico experiences seasonal hypoxia due to nutrient loading from the Mississippi basin, making nutrient removal from wastewater important for downstream ecosystem health.
