Community Input on Septic System Policy Updates

The County of Sonoma is updating County regulations for septic systems in order to meet state mandated regulations that protect water quality and public health. Permit Sonoma invites the public to participate in an online survey and to attend upcoming community meetings to share feedback on the proposed Onsite Wastewater Treatment System (OWTS) Manual.

“We welcome community input as the County revises its septic policies. Policies which could impact many of our rural residents. We are exploring creative solutions and some alternative technologies, along with permitting composting toilets at long last - which might help mitigate the stringent environmental regulations coming from our state regulators.” – Fifth District Supervisor Lynda Hopkins

Community Meetings

The community meetings will be held in September and October 2018.

These meetings will consist of a presentation on the County’s proposed septic system policies. There will be a question and answer session following the presentation, along with additional opportunities for attendees to share feedback. Members of the public who are not able to attend but would like to provide feedback are encouraged to watch the livestream of the workshop and share ideas through an online survey.

More Information

Second District Supervisor David Rabbitt emphasized that the County’s septic policies “need to balance housing needs and environmental impacts without adding unnecessary regulatory burdens on the residents responsible for maintaining their septic systems.”

Community feedback on these proposed septic system regulations will inform the draft Onsite Wastewater Treatment System (OWTS) Manual, which will be considered by the Sonoma County Board of Supervisors in November 2018.
