Safe digging in 4 simple steps

Regardless of your project’s size, you are legally required to contact Colorado 811 at least three business days before you dig. Fortunately, our free and efficient service makes it easy to request information regarding the location of underground public utility lines.

1

Contact 811

Visit colorado811.org or call 811 to request a free underground public utility line locate. This service protects public underground utilities such as gas, electricity, water, sewer, and internet lines. Remember, “privately owned utilities” won’t be included in this service.

2

Wait and Track your Ticket

Wait at least 3 full business days and track your ticket on colorado811.org. Utility companies will respond with a message indicating the status of your request.

3

Respect the Marks

If utilities are present, the location of the utility line will be identified by paint and/or flags. Once marked, maintain the marks to ensure they remain visible while digging so you do not hit the lines below.

4

Dig Safely, Dig Carefully

Dig with care, using extra caution near markings. Always dig cautiously with hand tools when digging within 18 inches of a mark or flag for a public utility line. Ask your landscaper or excavator do to the same.

Submit a ticket, check ticket status, access training, and see compliance resources in one place.
