Groundwater Well User Manual

This Groundwater Well User Manual, created in partnership with Permit Sonoma, is here to support you through any stage of being a well owner. Whether you are looking to drill a well, are a new well user, or have used a well for decades, this manual can help you navigate well maintenance and groundwater stewardship.

The manual is designed to:

  • Introduce new well owners and users to the basics of well construction, maintenance, and destruction;
  • Alert well owners and users to the potential for contamination and the need for water quality testing;
  • Provide information to well owners and users on ways to optimize well longevity and productivity;
  • Introduce well owners and users to groundwater sustainability programs available to them; and
  • Provide tips and resources to advance groundwater sustainability.

The manual has sections on well permitting requirements, well construction, well maintenance, water quality sampling and testing, water conservation, and how to participate in groundwater sustainability– all tailored specifically for well owners in Sonoma County.
