Excavators

Are you taking all of the steps for safe digging? If so, you must contact Colorado 811 at least three business days before digging. This will ensure facility owners will have their underground utilities located and marked with paints and/or flags.

How Colorado 811 Works

Everything You Need to Know

Quick Links

Colorado 811 does not provide locate services. Locate services are provided by the Underground Facility Owner or its agents who are independent of Colorado 811. Colorado 811 only provides notice of intended excavations to the Underground Facility Owners. The Underground Facility Owners will only locate the utilities they own and maintain to the meter or demarcation point. Everything on the backside of the meter or demarcation point is privately owned by the property owner.

Liaisons provide community support to Colorado 811 damage prevention stakeholders. They give safety presentations (Safe Digging Practices, Understanding the Law, Best Practices and more), Web Ticket Entry classes, speak at Toolbox Talks, and they attend community events to raise awareness of 811 and safe digging. Contact your local Damage Prevention Liaison if you are in need of any of these free services.

On May 25, 2018, Governor Hickenlooper signed Senate Bill 18-167 into law. This bill included the creation of the Underground Damage Prevention Safety Commission (Safety Commission), effective August 8, 2018.

In order to assist in preventing damage to underground facilities, the Safety Commission is charged with the following tasks:

  • Making recommendations regarding:
    • Best practices and training
    • Policies to enhance public safety
    • Policies to improve efficiency and cost savings to the 811 program
  • Reviewing complaints of alleged violations and ordering appropriate remedial action/penalties.
