UV disinfection: wastewater treatment plants in Kentucky
15 plants · 8% of the state · 7 MGD combined
Klarifi identifies 15 publicly owned wastewater treatment plants with uv disinfection in Kentucky, 8% of the 193 plants in the state (7 MGD combined). The largest is Radcliff STP in Radcliff at 1.86 MGD.
Ultraviolet disinfection destroys pathogens in the final effluent without chemicals or a chlorine residual. It has replaced chlorine at many plants since the 2000s and needs lamp, ballast and sleeve replacement on a fixed cycle, which keeps these plants in the market for UV suppliers.

Sources and methodology
Flow, permit and violation figures come from the EPA's ICIS-NPDES discharge monitoring records. Population served comes from the Clean Watersheds Needs Survey 2022. Treatment structures are identified by Klarifi's review of aerial imagery, and capital improvement projects are extracted from published municipal budget documents. Violations are counted over the last three years of monitoring reports.
