Contact Arizona 811 (dial 8-1-1 or go to Arizona811.com) from anywhere in Arizona at least two full working days prior to digging to get underground utilities marked. Knowing the location of buried facilities is the simplest and easiest way to  prevent accidental utility strikes, which keeps everyone safe; protects the vital utilities we all rely on every day; and protects the environment. Arizona 811 is a private, non-profit corporation, which provides these services statewide, which are free to anybody who is digging.

Arizona law (A.R.S. 40-360.21-32) says underground utilities must be marked before any type of excavation by anyone, including professional excavators, homeowners, sign installers and anyone else whose work disrupts the subsurface of the earth. This law is enforced by the Arizona Corporation Commission (ACC) Office of Pipeline Safety who can issue civil penalties of up to $5,000 per violation. You could also be liable for repair and reimbursement costs and possibly face legal action. For questions regarding enforcement of this law, contact the ACC at 602-262-5601.
