Because pipelines are underground and out of sight, you have to be careful where you dig.
Even markers indicating the right-of-way for transmission pipelines do not identify the precise location of the pipeline.
The only way you can be sure that you're digging safey is to have your proposed dig site reviewed for any underground lines.

It's easy to do. Simply call 1- 800- 424 -5555 two business days before you plan on digging.

The call . . . FREE.
Avoiding damage to a pipeline that could cause serious damage to you, your home, loved ones and neighbors. . . PRICELESS.

Digging anywhere in the state of Washington without calling two business days prior for utility locates is against the law. Even if digging on your own property, homeowners and farmers must make the phone call if digging deeper than 12 inches.

You only have to make one call. Owners of underground utilities, such as telephone, water, electricity, and natural gas, have cooperated in providing this one-call utility locate service.

Call Before You Dig Facts

How does the utility locate system work?
When you call the toll-free number (800-424-5555), your call is routed to a utility location request center operating in Washington. These centers are responsible for making sure participating utilities in your area are alerted to your digging plans and have the information necessary to determine whether a utility locate must be performed. In turn, the utility companies are obligated to make those markings within the two business day timeframe. To learn more about this process, visit the Washington Utilities Coordinating Council website.
