Nationally, every nine minutes an underground utility line is damaged because someone did not contact 811 before digging.
Knowing where underground utility lines are buried before you dig will help protect you and your family. Striking a single underground utility line can cause injury, repair costs, fines, and inconvenient outages. National Grid remains committed to keeping the public safe by emphasizing the importance of calling 811 to avoid damages or service outages in your local community.
“Whether you’re planting a tree or shrub, or installing a deck or pool, every job requires a call to 811 to know what’s below before digging,” said Mark Prewitt, Vice President of Pipeline Safety & Gas Compliance at National Grid. “The depth of utility lines can vary for several reasons, such as erosion, previous digging projects, and uneven surfaces. Utility lines need to be properly marked in each location, even one that’s previously been marked, to avoid risk. A call to 811 is the best safeguard to preventing strikes on underground utility lines.”
A quick phone call to 811 several days before digging connects callers to their local call center, which notifies the appropriate utility companies of their intent to dig. Professional locators then arrive at the digging site to mark the approximate locations of underground lines with flags, spray paint, or both. The service is easy to use, free of charge and is required by law.
Calling 811 before digging is easy, free, and is the law.
State laws mandate that 811 must be contacted 72 hours in advance of beginning projects that require excavation, excluding weekends and legal holidays. Additionally, the parties requesting to dig must mark the requested areas of excavation.
