Call Before You Dig – Call 811

Avista reminds you safe digging is no accident; call 811 before you dig

Before beginning any outdoor digging project, call 811 at least two business days before you dig. Calling 811 will get a professional locator to your site to mark the approximate location of underground utility lines. There is a two-foot tolerance zone on each side of the line, and it is required to hand dig to determine the precise location of the utility in this tolerance zone. This service is free. Remember, you may have your own utilities that require a Private Locate request at 811.

Knowing where underground utility lines are buried before you dig will help protect you from injury, prevent damages to utilities and service disruptions, and avoid potential fines and repair costs. Underground utility lines can be just about anywhere, so keeping your shovel in the shed or garage and calling 811 first is a smart move (and it’s the law).

Every digging job requires a call — even small projects like planting trees and shrubs. The depth of utility lines varies and there may be multiple utility lines in a common area. Here are just a few examples of when to call:

• Installing a rural mailbox

• Putting in a fence

• Planting a tree or shrubbery

• Building a patio or deck

• Excavating a new garden area
