1. My septic system is working fine. Why do I have to have it inspected?

- A septic system can impact public health and the environment in a variety of ways. Some are not as obvious as surfacing sewage or a clogged toilet. A careful inspection of the system dramatically increases the chance that problems will be discovered, and can then be corrected. In addition, regular inspections of a septic system should lead to a longer life for the system by fixing small problems before they become big problems.
- Jefferson County Code 8.15 requires that a septic system be inspected to assure that it is working properly. View the Jefferson County Code 8.15 (PDF).

- A conventional gravity system must be inspected every 3 years.

3. Does my tank need to be pumped every time it is inspected?

No. The inspection will determine if your tank needs to be pumped. In general the tank will need to be pumped when the solid contents equals 1/3 of the tank volume; when the scum and sludge layers exceed 6 and 12 inches respectively; or for other reasons noted by your inspector.

4. Do I need to be present at the time of the inspection?

It is strongly recommended you be present during the inspection but it is not required.

The cost of an inspection will vary depending on the size, complexity and how accessible your system and its components are. Contact a certified operations and monitoring specialist.

6. Who pays for the monitoring inspection?

7. How do I prepare for the monitoring inspection?

The inspection ports on the top of the tank must be uncovered and loosened so that the solids in the tank can be measured and components checked. Any monitoring ports in the drain field or treatment system need to be accessible for inspection. Many septic system records images have been scanned. This may help you in locating tanks and other system components. Viewing these records via the Permit Files Online page.

8. What will the county do if I don’t have my system inspected?

There are no other upgrades that are required by the county unless repair are needed related to a system that is failing.

10. What happens if the inspection reveals that something is wrong with my septic system?

- Many of the problems identified are items that, if not corrected, can lead to premature failure. It is the responsibility of the system owner to make sure the corrections are made.
- Simple repairs such as replacing a septic tank baffle or broken lid can be done by the homeowner or other certified professional without a permit.
- If the problem is serious, the system is failing, backing up in the house or discharging on the surface of the ground or if components were installed without permits, you may be required to repair or replace your septic system. A permit will be required, and you will need to work with a licensed designer or professional engineer.
