Septic maintenance contract rules in Texas
Texas maintenance contracts for aerobic systems are set by TCEQ (TCEQ OSSF maintenance page). The contract must be with an individual licensed maintenance provider. TCEQ no longer registers maintenance companies.
What the provider must do (minimum)
- Tag the system at the start of the contract and punch or mark it on every visit, including complaint calls.
- Inspect every component and note whether it is working.
- Test the system as required by 30 TAC §285.91(4).
- Report to the permitting authority and to the owner at least once every four months, within 14 days of the test.
- Reporting can drop to once every six months if the system has electronic monitoring that alerts the provider to failures and tracks disinfection.

Switching providers
You can change providers when your contract term ends, or earlier if the contract allows it. Your new provider files reports with the same permitting authority, so give the new company your permit number. Many permitting authorities also ask for a copy of the new contract. Get quotes from local providers.
