Operation and Monitoring (O&M) Inspection
Septic System Inspection Requirements
If you own a septic system, you are required by state and local code to check your septic system on a regular basis to make sure it is working properly. How often you need to check your septic system depends on the type of system you have:
|Every 3 Years|
|Conventional Gravity Feed||X|
|Pump to Gravity|
|Pressurized Septic Systems|
|Aerobic Treatment Units|
|Proprietary devices including Glendons and drip irrigation|
|Food Service Establishments|
Property owners have two options for getting their on-site system inspected:
- Hire a Professional Operations and Monitoring Specialist or Licensed Septic System Designer
- If eligible, you can conduct the inspection yourself (DIY).
Professional Inspection Requirements
All on-site sewage systems require a professional inspection by a Certified O&M Specialist or Licensed Designer at some frequency. View a table showing the required frequency of inspection by a professional (PDF) A professional inspection is also required in the following cases:
- At the time of sale of property or transfer of title an inspection by a professional is required to be on file in compliance with the required inspection frequency.
- At the time of application for a building permit or other governmental actions such as land divisions, conditional use permit, boundary line adjustment, an inspection by a professional, compliant with the required frequency, must be on file. An inspection that involves more than a standard monitoring inspection may be needed for some building projects.
- In general, community and commercial septic systems must be inspected by a professional in Jefferson County. Authorized homeowners connected to a community septic system may inspect their own individual septic tank (and pump chamber if applicable) unless a maintenance contract or Homeowners Association Agreement requires a professional inspection.
Please visit the certified professionals page for a current list of professionals operating in Jefferson County.
If you own a septic system in Jefferson County, you may be eligible to inspect your own septic system. See the Homeowner Authorization for Septic Inspections page for more information.
