Key takeaways

  • 811 connects you to the one-call service that marks public utilities
  • Private lines such as your sewer lateral are usually not marked by 811
  • Locates should be requested before any digging or boring
  • Private locating complements 811

What 811 is

In the United States, 811 is the national number for calling before you dig. It routes your request to the state one-call center, which notifies member utilities to mark the location of their buried lines near your project.

Marking is done with paint or flags, color-coded by utility type.

Why it matters

Hitting a gas, electric, communications or water line is dangerous and costly. Locates are required by law before most digging, and trenchless methods that bore or open pits are covered as well.

Always allow the time the one-call service specifies before starting.

What it does not cover

811 marks public utilities. Your private sewer lateral, a private gas line to a grill or an irrigation system is usually not marked. That is where private locating, with a camera transmitter and a surface receiver, helps.

Private locating ensures we know where your pipe is as well as where the public lines are.

How we handle it

We request locates before opening any pit, bore or excavation and confirm the markings before work begins. We also locate your private lines. If markings are missing or unclear, we stop and ask.

Property owners can also call 811 for projects like fences, planting and pools.
