In the past, most utility lines were strung overhead; in this day and age public utilities have gone underground. Everything from telephone lines, to cable television lines, to gas and power lines, and even sewer lines are buried at varying depths. It is important to handle these lines with care. A knick or a cut to any of these lines can disrupt your residential utility service.
In Colorado, smart digging means calling 811 before you start any outdoor job to have your utility lines located and marked. Digging without calling can disrupt service to an entire neighborhood, harm you and those around you and potentially result in fines and repair costs. Calling 811 before every digging job ensures your underground utility lines are marked for free, and helps prevent undesired consequences. *
