Underground Damage Prevention

New Hampshire’s Underground Damage Prevention Program protects excavators, utility operators and the general public from the significant dangers associated with damage to buried gas, power and other utility lines. The New Hampshire Department of Energy is responsible for enforcing the underground utility damage prevention program within our state to ensure public safety and minimize damage to underground facilities.

New Hampshire is served by Dig Safe System, Inc., a not-for-profit corporation located in Wilmington, Massachusetts which also services the states of Maine, Massachusetts, Rhode Island and Vermont as a Clearinghouse Center.  Excavators are not charged for use of the system. The notification procedure is initiated by one of two methods:

Dial 811 or 888-DIG-SAFE® – Monday through Friday (except holidays) From 6 am to 6 pm. During off- hours, only emergency notifications are processed.

Exactix allows the excavator to process routine and emergency Dig Safe® tickets online 24 hours a day, 7 days a week after the excavator’s initial registration. The excavator uses their own Exactix dashboard to store and manage all ticket data, including their Dig Safe number, legal start date, and a list of members notified.
