If you have an aerobic treatment system in Oklahoma, there's something you need to know: state law requires you to maintain a service contract with a licensed aerobic system provider. It's not optional — it's part of your DEQ permit.
Why Oklahoma Requires Maintenance Contracts
Unlike conventional septic systems, aerobic systems have active components — electric aerators, chlorinators, spray heads, and control panels — that require regular attention to function correctly. An unmaintained aerobic system can fail to treat wastewater properly, creating a public health risk and a code violation.
What's Included in a Maintenance Visit
- Inspect the aerator and verify it's functioning
- Check the chlorine level and refill the chlorinator
- Test the spray heads to confirm they're operating
- Check the control panel for alarm codes or fault indicators
- Inspect tank levels and check for signs of system problems
- Document the visit and submit reports to DEQ as required
What You Can Do Between Service Visits
- Alarm light or sound: If the alarm activates, don't silence it and ignore it. Note the indicator and call your provider.
- Spray heads: Periodically check that all spray heads are working. A stuck or broken head is an easy fix if caught early.
- Chlorine: If your provider leaves tablets, add them as needed between visits.
- Odors: A properly maintained aerobic system should not smell. Odors can indicate low chlorine or a system problem.
What Happens If You Let Maintenance Lapse?
Letting your maintenance contract lapse puts you out of compliance with your DEQ permit. Beyond the legal issue, an unmaintained aerobic system will eventually fail — and when it does, repairs are more expensive than staying current with maintenance.
