Before You Dig


AZ811 was established as a 1-call notification system by underground facility owners such as water, cable, gas, telephone, and electric to assist excavators in notifying underground facility owners prior to digging. This damage prevention service is provided free of charge to any individual or company planning to dig. The following information will provide you valuable knowledge before you dig.

What You Should Know Before You Dig

Before you do any digging, or hire a company to dig (or excavate), the law says you must first contact AZ811 to determine whether or not there may be underground utilities at your dig site. Underground utilities are generally located in the easement either in your front yard or an alley if your home backs up to one.

Homeowners, excavators, and utility companies all have certain responsibilities that must be met prior to any digging taking place. there are also several different colors used for marking utilities, depending on what utilities actually exist at your dig site.

 Program Participation

By participating in the Arizona811, you are:

  • Complying with state law - Arizona's Damage Prevention Laws, Occupational Safety and Health Administration (OSHA), and Arizona Corporation Commission (ACC) Rules require all utility owners to clearly mark any utility that may conflict with any ground digging.
  • Avoiding injuries - Incident damage to utilities can cause injury to anyone near the dig site.
  • Preventing costly damages and interruptions of facility services - Clearly marking the utility before digging reduces potential interruption of utility services to customers.
  • Saving time and money - Utility accidents can slow down construction schedules and can be costly to repair.
  • Avoiding hazards - Clearly identifying utility locations through the Arizona811 procedures allows construction activities to avoid potential hazards.
  • Eliminating needless construction delays - Avoiding incidental utility damages keeps construction schedules on time, reducing noise, service interruptions, traffic congestion, and annoyance to local neighbors.
