ADAIRVILLE STP is a municipal wastewater treatment facility located in Adairville, Kentucky, a small community in Logan County. The plant serves a population of approximately 920 people, reflecting its role as a small-scale treatment facility for the local area. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater treatment. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's designed capacity is 984.20 million gallons per year, and it currently discharges 124.92 million gallons annually, indicating significant reserve capacity. The treated effluent is discharged into a local waterway that ultimately drains into the Red River, a tributary of the Cumberland River, which flows into the Ohio River and then the Mississippi River. This downstream connection highlights the plant's role in protecting water quality within the larger Mississippi River Basin, which supports diverse aquatic ecosystems and serves as a critical water resource for the region.

The plant's discharge enters a local stream that flows into the Red River, a tributary of the Cumberland River. The Cumberland River eventually joins the Ohio River, which is a major tributary of the Mississippi River. This watershed supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, contributing to the ecological health of downstream waters.
