The UNCC (Utility Notification Center of Colorado) is the designated organization that manages all types of ground excavation in the State of Colorado.  The main goal of this organization is to prevent human injuries and damages to underground utilities due to digging. 811 is the new federally mandated number that you should call, if you wish to start a digging project.

The wastewater underground utility locates section of the City and County of Denver is now a Tier 1 member of UNCC 811. They are no longer receiving locate requests by voicemail or email. All locate requests are to be made by contacting UNCC 811.
