Underground Utility Locate Services in Colorado

Colorado 811, officially known as the Utility Notification Center of Colorado, does not provide locate services directly. Instead, it serves as a free, state-mandated service that allows excavators, homeowners, and other property owners to notify registered owner/operators of public underground utilities about their planned digging projects via a One-Call communication pathway. This ensures that public underground utility lines are marked before excavation, preventing accidental damage and ensuring safety.

Locate services, both for private or public underground utilities, are provided by either the underground facility owner/operator, private locating companies, or third-party locating firms contracted by utility owner/operator facilities. Since not all underground utility lines are covered by an 811 request for locate, it is critical that you identify if you need to have a private or public utility located before the excavation occurs.

Colorado 811 provides the displayed contact information of entities listed on this page as a courtesy and is not responsible for the accuracy and totality of the information. Colorado 811 members or private locating firms provide the contact information displayed voluntarily and are responsible for the timely submission and accuracy of any contact information by regularly informing Colorado 811 of any updates or changes.
