Call 811 before you dig

It is required by Arizona law that underground utilities be located and marked before any type of project involving digging begins. It only takes a few minutes to be in compliance with the law, limit your liability and stay safe: call 811 (formerly Arizona Blue Stake, Inc.) or visit Arizona811 to create an online ticket before digging.

Accidents involving contact with underground electrical power lines not only can damage equipment, but also cause serious injuries and even death. Be sure you know what to do if someone comes into contact with an energized power line.

When to call

In general, you should call 811 anytime you are digging on your property. Some of the most common reasons include:

  • sprinkler installation,
  • planting a tree, general landscaping (gardening, gravel installation, planting flowers),
  • installing pavers or a driveway and,
  • project planning.
