Call Before You Dig

Preventing Underground Utility Damage

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.

How to Request a Locate

At least two business days before you plan on digging:

Be sure to provide the following information:

  • Where you're planning to dig, and
  • What type of work you will be doing.
Uniform Color Code for Underground Utility Lines.  White, proposed excavation. Pink Temporary survey markings. Red electric power. Yellow, Gas, oil, steam, petroleum. Orange, communications.

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.

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.

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, follow the APWA color codes so you'll know what's below - and be able to dig safely.

811 Marking Guide

Private Utilities

Some underground lines in your work area may not be utility-owned. These are considered private facilities and will NOT be marked by public utility companies. Types of private facilities include, but are not limited to, heating systems for pools, electricity for an outbuilding, invisible fences, fiber optic lines, septic systems, and satellite dishes. If you think you may have private facilities you should contact a private utility locator to identify and locate them.

Dig Law for Realtors

When installing any type of sign, including those used for real estate, a locate must be requested. Residential yards have numerous underground utility lines that can be damaged when installing a sign. Not only is damaging an underground utility costly, it also poses a safety hazard.

Smart Digging

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.
