State guide

Kentucky

Kentucky runs its onsite sewage program through local health departments rather than a state environmental permitting office for routine home systems. The state program says local health department septic inspectors perform site evaluations and inspections, and installation is then done by a certified Kentucky onsite septic installer.

What to do next

  1. Contact the local or district health department first and ask for the site-evaluation application before paying an installer.
  2. Plan for the local inspector's site evaluation and any requested backhoe pits, because Kentucky local health departments use that evaluation to determine system suitability.
  3. After the site evaluation, use a certified Kentucky onsite septic installer unless you qualify for a homeowner permit through the local health department.
