Call Before You Dig

Call 811 before you dig

What to Expect

A representative will take information about your project and notify the appropriate utility companies. They will then come to your site and mark any underground utility lines, including power and gas lines, communication cables, and water lines.

Why Call?

Hitting a buried utility cable may cause property damage, injury or death. Sometimes these lines are buried at a shallow depth. What’s more, the law requires anyone planning to do digging, blasting or tunneling work to have the utility lines at the site marked before beginning the job. Even seemingly simple tasks like installing a mailbox, planting a tree, or building a deck require a call to 811.

Whether you’re a contractor, farmer or homeowner, know what’s below: call 811 before you dig.
