Well Construction For Property Owners

The following information is provided to help property owners make informed decisions before drilling a new well or decommissioning (filling in) an old well.

Important Information for Private Well Owners

Before you start the process, please open and read the Homeowners Guide to Well Construction.  It includes information about well drilling and the Washington State Well Drilling Regulations.  It is important that you meet all the requirements for new or decommissioned wells.

In April, 2005, Gov Christine Gregoire signed a new law that updates the fee structure for water wells, and adds a fee for decommissioning wells. This is the first time the fee structure has been amended since adoption in 1993. The statute will also add definitions for Ground Source Heat Pump Borings and Grounding Wells that will soon become regulated.

Other changes include: Adding or modifying the delegation authority, complaint, continuing education and reporting provisions; providing a suspension period at the end of a license term if license renewal is not completed; and modifying the technical advisory group composition provisions.

State Water Use Laws: The Ground Water Permit Exemption RCW 90.44.050

The groundwater permit exemption allows the users of small quantities of ground water to construct wells and develop their water supplies without first obtaining a water right permit from Ecology.
