SONOMA COUNTY OWTS HUB







ABOUT THE HUB

This website is being used to inform and provide resources about waste water
treatment systems within Sonoma County.  Scroll down to access the mapping tool
and find more information. 

The OWTS Interactive Mapping Tool is an application that is part of a larger
study that maps and analyzes Onsite Wastewater Treatment Systems (OWTS) across
Sonoma County. OWTS, commonly referred to as septic systems, are subject to
increasingly stringent regulations, especially in areas near waterways impaired
with pollutants such as excess pathogens, bacteria, or nutrients. Improved
understanding of the county’s OWTS situation will assist with efforts to keep
the water clean and fulfill regulations. The study is designed to increase the
County’s understanding of OWTS on a countywide scale and analyze the challenges
and opportunities for wastewater treatment alternatives, including management
and support options. For more information on how parcels were categorized as
"Known" or "Suspected" OWTS, please refer to the "OWTS Analysis Report" under
the Resources section.
