STURGIS STP - Advanced Wastewater Treatment in Union County, Kentucky

STURGIS STP is a municipal wastewater treatment facility located in Union County, Kentucky, serving a population of approximately 1,800 residents. The plant operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges into surface waters. As an advanced treatment facility, it provides a higher level of pollutant removal than secondary treatment, ensuring compliance with stringent water quality standards. The plant has a designed capacity of 1,892.70 units and currently processes an average daily flow of 832.79 units, indicating operational headroom. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) and disinfection, which are critical for protecting sensitive downstream environments. The treated effluent from STURGIS STP discharges into local streams that flow into the Ohio River, a major tributary of the Mississippi River system. The Ohio River supports diverse aquatic life and provides drinking water for millions of people. The plant's advanced treatment helps reduce nutrient loading and protect water quality in this ecologically and economically significant watershed.

STURGIS STP discharges into local waterways that drain into the Ohio River, which flows southwest to join the Mississippi River and ultimately the Gulf of Mexico. The Ohio River basin supports a wide range of aquatic species and is an important migratory corridor for fish. Advanced treatment at this plant helps minimize nutrient pollution, which can cause algal blooms and hypoxia in downstream waters, including the Gulf of Mexico dead zone.
