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]).
