Operation Maintenance & Monitoring (OM&M)

If you have a supplemental treatment system such as a sand filter, Advantex, or Hoot, that was permitted after January 1, 2005, you are required to have a service provider perform annual maintenance on your system. You should receive a reminder from Placer County every November, and you must have the service performed by the end of February. Billing for the OM&M program is mailed out in January.

All septic systems require a lot of care to ensure that they function properly. Please refer to our recommendations below and Frequently Asked Questions to keep your system running properly for as long as possible.
