      • Overflow Advisory Levels
      • Integrated Overflow Abatement Plan
      • CSO/SSO Location Maps
  • Paducah, KY
    • Two major projects are planned which will eliminate or reduce the frequency, volume and duration of CSOs. Those projects are: (1) Paducah wastewater treatment plant upgrade – the hydraulic capacity of the WWTP will be increased from 9 to 17 MGD, allowing more wet weather flow to enter the WWTP, and (2) Perkins Creek Interceptor Separation – the scope for this project is to separate Perkins Creek Lift Station (1.5 MGD) flow from the Combined Sewer System.
    • Paducah is expected to complete a design soon for a stand-by generator for its influent pump station, thus reducing bypasses during power outages.
