If you own a septic system in Jefferson County, you can inspect your own septic system if all of the following criteria are met:

Your septic system is one of these:

  • conventional gravity
  • pressure distribution
  • mound
  • sand filter

Other system types such as aerobic treatment units, biofilters, drip irrigation and all systems with proprietary devices are ineligible for homeowner inspections and must be evaluated by a professional at the frequency required in state code.

  • The septic system is a residential system serving a single-family residence or duplex on property you own.
  • There is an adequate record of the systems location on file at Jefferson County Environmental Health.
    • If the County has no record of a septic system on your parcel you will need to work with a certified operations and monitoring specialist or licensed designer to create a system location site plan for the property. The site plan must show the septic system components such as the septic tank and general drain field area along with the well (if applicable), house, garage, sheds and other outbuildings, driveways and the adjacent roadway. Click to view a sample site plan and a blank site plan.
    • If the records we have are inadequate we will ask you to contact the Environmental Health office, and together we will try to determine if there is enough documented information about your system. If there is not enough information to determine your system type and where its components are located you will be required to submit a system location site plan developed by a certified/licensed professional before your system will be eligible for you to inspect it.
    • After submittal of the system location site plan, you may qualify to inspect your own septic system if you meet the other criteria.
  • You successfully complete a County-approved septic system training and certification program and pay the current homeowner authorization fee.
