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.
