London Wastewater Treatment Plant, Laurel County, Kentucky

The London wastewater treatment plant is located in Laurel County, Kentucky, serving the city of London and surrounding areas. With a population served of 16,876, it is classified as a medium-sized municipal facility in the southeastern United States. As a U.S. facility, the plant operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which is part of the Clean Water Act. This regulatory framework requires secondary treatment as a minimum standard for municipal wastewater plants, with more stringent limits for sensitive water bodies. The plant's treatment processes and capacity are designed to meet these federal and state requirements. The plant discharges treated wastewater into local waterways that ultimately drain into the Cumberland River system, a major tributary of the Ohio River. The receiving waters support diverse aquatic life and are used for recreation and drinking water downstream. Proper treatment is essential to protect water quality in this ecologically important watershed.

The London plant discharges into the Laurel River watershed, which flows into the Cumberland River, a major tributary of the Ohio River. This river system supports diverse fish populations and provides habitat for freshwater mussels. The treated effluent must meet state water quality standards to protect downstream aquatic ecosystems and drinking water sources.
