There are thousands of abandoned wells in Washington. If you find an abandoned well on your property, you are required to work with a licensed well driller to properly close it up, a process called “decommissioning.”
Abandoned wells can be hazardous to people, animals, and the water supply. Landowners may be responsible for any injury or groundwater contamination caused by an abandoned well that was not properly decommissioned.
How to decommission a well
Property owners cannot legally decommission a well themselves. They must contact a licensed well driller to decommission it. The cost of decommissioning a well depends on its depth, diameter, and the geologic conditions in your area. Special equipment may be required.
To decommission a well on your property:
- Find a licensed well driller*
- Send us a notice of intent (NOI) to decommission a well
- The NOI must be sent at least 72 hours before the work begins.
- Use this NOI online form to decommission a well
- Pay the well decommission fee
- When you complete the NOI online form, a link appears so you can pay online
- Decommissioning a water well is $50

How to identify an abandoned well
Wells are often located in the basements of houses, under porch steps, or near cisterns and windmills. Knowing the history of your property may help you find any abandoned wells. You can also look for the following signs:
- Pipes sticking out of the ground
- Old well houses
- Depressions in the ground or lawn
- Concrete vaults, pits, or tile
- Old plywood lying on the ground or over concrete tiles or vaults
Finding abandoned wells can be a dangerous activity. Only look for an abandoned well when accompanied by another responsible person. Keep your own safety in mind at all times.
Old wells that were dug, not drilled, are the most dangerous because they are often wider than modern wells. Many dug wells were originally used for crop irrigation but often become obscured by brush or vegetation. People or animals can easily fall into a dug well that has not been properly capped. Old well caps can weaken over time, creating a hazard. The law requires all wells to have a proper cap.
