Washington Utilities and Transportation Commission
The only way you can be sure that you are digging safely is to Call 811 Before You Dig, and request a FREE underground utility locate.
At least two business days before you plan on digging:
Be sure to provide the following information:
You will also need to outline your dig area with white paint before you call; this helps utilities identify your dig area quickly and accurately.
Affected local utility companies will be notified about your intent to dig. They will send a locator to mark the approximate location of your underground utilities, following the color codes to the right, so you'll know what's below - and be able to dig safely.
Digging anywhere in the state of Washington without calling for a utility locate is against state law. Failure to call may result in fines, charges for damages, and criminal convictions.

When digging within two feet of the marked area, only use small hand tools such as a garden trowel to carefully expose the utility line. Keep in mind that utility installation is not the same for all utilities and requirements have changed through the years. Not all utilities are installed with protective casings and can be vulnerable to damage by tools as simple as a shovel. Always proceed with caution when digging around utility lines.
If a locate was late, inaccurate, or incomplete - report it to the UTC. Call 1-888-333-WUTC (9882) or email firstname.lastname@example.org. You can also file a complaint with the Washington Dig Law Safety Committee.
