Key facts
- New installs, modifications and repairs must be inspected by DEQ or self-inspected by a DEQ-certified installer before backfill (DEQ rules, OAC 252:641, 252:641-1-3).
- Aerobic system installers must maintain the system for 2 years at no extra cost; after that it is the owner's job (DEQ rules, OAC 252:641, 252:641-10-3).
- Edmond requires owners of aerobic systems to give the City yearly proof of professional maintenance after the first 2 years (City of Edmond aerobic maintenance page).
- Oklahoma does not require a septic inspection when a home is sold, but buyers can order one (OSU Extension: Basic Septic System Rules for Oklahoma).
