811 Dig Safe

Construction season is upon us once again! In our continuing quest to promote Underground Damage Prevention, the Safety Division of the PUC instructs Homeowners, Professionals and Government Agencies to use the 811 DigSafe phone number. Not only is 811 easier to remember, it’s FREE. Remember – always call 811 before you dig – it’s the law!

The Governors of New Hampshire continually recognize the importance of underground damage prevention and proclaim each April as Safe Digging month. The current proclamation is available here.
