If you plan to dig anywhere, from home projects to large construction jobs, you must contact 811 before you dig. Thousands of miles of pipeline, wires and cables for critical services such as electricity, natural gas, water, sewage, communications and other utilities are located underground. Damaging these lines could result in large utility outages, expensive repair costs, and could cause injury or even death.
811 Before You Dig. Call 8-1-1, or visit Colorado811.org at least three business days before you dig.
Colorado 811 will notify affected utility owners of your intent to dig. Be sure to provide access to the property, ensuring gates are unlocked and pets are secured until the locates have been completed. If there is a problem with access, a meet request may be processed to ensure accessibility.
