Grand Rivers Lake City STP - Livingston County, Kentucky Wastewater Treatment Plant

Grand Rivers Lake City STP is a municipal wastewater treatment plant located in Livingston County, Kentucky, United States. The facility serves a population of approximately 2,250 residents and operates with a designed capacity of 1,892.70 thousand gallons per day, currently treating an average of 916.07 thousand gallons per day. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. Under the National Pollutant Discharge Elimination System (NPDES) permit program, plants of this scale are typically regulated by the Kentucky Division of Water to ensure compliance with effluent limits that protect water quality. The plant's discharge enters a receiving water body that ultimately drains into the Ohio River basin, contributing to the larger Mississippi River watershed. The proximity to the coast (within 10 km) indicates that the treated effluent may influence nearby aquatic ecosystems, including the Tennessee and Cumberland River systems that feed into the Ohio River.

The plant discharges into a water body that flows into the Ohio River, a major tributary of the Mississippi River. The surrounding watershed supports diverse aquatic life and is an important migratory corridor for fish species. The plant's coastal proximity (within 10 km) means its effluent can affect local water quality in the region's interconnected river and lake systems, including the nearby Land Between the Lakes National Recreation Area.
