Well and Septic Systems

The Well and Septic Division staff reviews all development proposals that will rely on wells or septic systems. They also review permit applications for septic system repair or upgrade. Their focus is on protecting health by ensuring that water wells are properly constructed and septic systems protect surface and ground water quality. Sonoma County's soils are notoriously poor for septic systems, so this is a sometimes challenging mission.

Well Water Recommendations and Requirements After Wildfire Storms

As an owner of a private domestic water well that may be damaged by a wildfire, you may have some concerns about fire related impacts to your well and water system. Sonoma County recommends the well owner perform a visual inspection of their well and water system, including the piping and plumbing that provide water to and throughout your home.
