Aerobic septic systems: maintenance rules
The first 2 years: installer's job
Under 252:641-10-3, the installer must maintain a new aerobic system for 2 years at no extra cost: fix broken parts, and at least every 6 months test chlorine (spray systems), measure sludge, and do a clarity test of the pump tank, notifying the owner in writing each visit (DEQ rules, OAC 252:641; DEQ aerobic systems fact sheet). If an installer does not do this, DEQ asks owners to call 1-800-522-0206.
After 2 years: owner's job
The owner must maintain the system or hire someone to maintain it so it works as designed (252:641-10-3(c)).
Edmond's extra rule
Edmond requires builders of new homes with aerobic systems to provide a 2-year maintenance agreement (Ordinance 3477, section 21.03.091). After 2 years, the homeowner must give the City yearly verification of continued professional inspection and maintenance (City of Edmond aerobic maintenance page). The City also recommends checking chlorine monthly and calling a septic professional right away if the alarm goes off.
Owner checklist
- Keep chlorine tablets stocked (spray systems).
- Do not ignore the alarm light or buzzer.
- Keep sprinkler heads clear and the spray area free of play areas.
- Keep service records.
