Onsite Sewage Disposal Systems

Local health departments administer the inspection and permitting of onsite sewage disposal systems including septic systems. The Lincoln Trail District Health Department Environmental office provides inspections for septic systems in Hardin, LaRue, Marion, Meade, Nelson, and Washington Counties.  Professionals at your health department help with everything from evaluating a potential site for your system to providing advice for keeping your system well maintained.

If properly designed, constructed and maintained, a septic system can provide long-term and effective treatment of wastewater for homes or businesses without access to city sewage.  What goes down your drain has a big impact on your septic system.

  • Use water efficiently and stagger use of water based appliances to avoid a backup of your septic system into your house.
  • Avoid harsh chemicals and use cleaners and detergents in moderation.
  • Disposable diapers and wipes, cat litter, paper towels, cigarette butts and many more products should not be disposed of in the toilet.
  • If a septic system isn’t maintained it might need to be replaced, costing thousands of dollars.
  • A malfunctioning system can also contaminate groundwater that might be a source of drinking water.

Below are some examples of different types of septic systems layouts.

Approval Process for a New Septic System

  1. Person chooses a building site for their house, mobile home or commercial establishment.
  2. Person, or their agent, submits an application for a site evaluation to the Health Department. Site evaluation requests may be submitted online or completed at your local Environmental office. For more information about completing a site evaluation request online, see below. Items required on the application include:
    1. Specific address and/or location of the site.
    2. Site boundary lines and dimensions of site should be staked and a survey plat copy submitted.
    3. Locations of existing structures, wells, ponds, streams, easements, roads, drives, etc., if present.
    4. Proposed or existing location of structure to be served by the system, and proposed system location marked (area to be tested).  Also mark any proposed alternative area.
    5. For homes: Number of bedrooms, if a garbage disposal will be installed and if the house will have a basement.
      For commercial use: Type of business, number of employees and shifts, type of plumbing fixtures proposed and related information.
  3. Site evaluation fee of $300 must be paid when the application is submitted.
  4. If the site evaluation results reveal that there is a usable area for possible septic system installation, then the inspector will mark that area. This area is not to be disturbed by grading, heavy equipment traffic, placement of building materials or any related action. This is to prevent compaction and soil structure damage that could negatively affect the system’s ability to function. Any disturbance of the approved area in the manner described could void the site evaluation.
  5. A copy of the site evaluation report will be provided to the applicant. On the report, the inspector’s soil characteristic findings will be listed along with the minimum system option information. Specific system component requirements related to any options are the responsibility of the certified installer. However, should the installer or applicant have any questions regarding such information, please contact the health inspector for additional information.
  6. If the site received a suitable or provisionally suitable overall rating, then the certified installer may apply at the Health Department for a permit to install the septic system. At that time, all required paperwork must be submitted along with the permit fee. Permit will be based on site evaluation findings regarding site characteristics and the installer’s system design proposal.
  7. Once the installer puts in the septic system, they must then request an inspection from the Health Department before any of the work is covered.

Existing System Inspections
