Before you dig, you must contact Colorado 811. Pipes, electrical wire, fiber optic cable, gas lines, sewers and other utilities are often buried underground. Damage to utilities could cause injury or death and result in an expensive repair. Even if you are doing a simple landscaping project, it is imperative that you contact Colorado 811 at least three working days before you plan to work.
The City and County of Denver locates main sewer lines only. The service line (lateral) line is the responsibility of the property owner up to and including the tap into the main sewer line.
