Well Construction or Decommissioning Inspection

Thurston County Environmental Health Division must be notified three (3) business days prior to constructing or decommissioning a well. If you are requesting a replacement well, please include your reason for this request along with your Well Construction / Decommissioning Application [PDF].

Staff will review the well construction or decommissioning. The well construction or decommissioning must meet Department of Ecology (DOE) and Thurston County Sanitary Code Article III [PDF] requirements.

There is no Thurston County fee for these inspections; however, there is a fee for review of the well site location if the well is to serve as the drinking water source for a public water system. For additional information, see Well Site Supplemental Application [PDF] and Well Site Application Guidelines [PDF]).
