Call 811 Before You Dig

State laws requires you to call a free utility marking service before digging on your property.

Massachusetts, New Hampshire: Dig Safe

Call 811 or 888-DIG-SAFE (888-344-7233) at least 72 business hours prior to digging. Or visit Dig Safe to request service online.

Connecticut: Call Before You Dig

Call 811 or 800-922-4455 at least 48 business hours prior to digging. Or visit Call Before You Dig to request service online.

What happens next?

After you call, member utilities will come to your site and mark underground utility wires, cables and pipelines.

This important, free service can protect you from:

  • Unintentionally hitting underground utility lines which can cause harm to you and those around you
  • Disrupting service to an entire neighborhood
  • Potentially making you liable for fines and repair costs

Property owner responsibility

Please note that member utility companies will only mark the facilities they own or maintain. Private underground pipes and cables may not be owned or maintained by member utility companies.

It is the responsibility of the property owner to investigate if any privately owned utilities are in the area.

You can download and print a word search puzzle to see if you "Know What's Below."
