BEFORE YOU EXCAVATE, call Arizona 811, it's the law! Whether you're a homeowner or an experienced contractor, this is the safest way to prevent shocking or explosive surprises - surprises like underground electric, water, gas, cable, sewer or telecommunications lines. One call to the Arizona 811 Center is all it takes, and the facility owner will come out and mark the precise location of their lines for FREE.

Arizona 811 Center is a damage prevention service offered FREE of charge to any individual or company planning to excavate, it is a one-call notification system established to assist excavators in locating all underground electric, gas, water, telephone, sewer, communications or other lines prior to excavation.

Before you excavate, as required by state law and for your safety, please call 811, the underground facility owner will have two (2) working days to give you a positive response. Once the facility owners mark their lines, the exact location of all buried facilities MUST BE EXPOSED WITH HAND TOOLS IN A CAREFUL AND PRUDENT MANNER when working within 24” of a marked facility. Even when digging with hand tools, use caution to prevent injuries and damage to the facility. The uncovered facility must be supported and protected prior to and during your excavation (see Arizona Revised Statutes § 40-360.21 for the definition of “Careful and Prudent”). If for any reason you need assistance in safely exposing, supporting and protecting a facility, please contact the member underground facility owner(s)/operator(s) directly.

You may ask yourself, what is the penalty for failure to comply? First and foremost, if you fail to follow the law, you put yourself and others around you in danger.
