National Grid
Know what's below. Call before you dig. Planting a tree? Installing a fence? Planning a home improvement? Then call 811. Did you know it's the law? Electric power lines, natural gas pipelines, water pipes, communications lines and other utility services can be within a few feet of the ground. Not knowing where they are can result in personal injury, property damage and neighborhood service interruptions. Even a small dent or a scrape can cause damage, resulting in a leak or service-wide disruptions.

If you're planning any type of excavation, call 811 at least two full working days before digging, drilling or blasting. This national service, which is performed at no cost to you, helps keep you and your loved ones safe. When you call 811, the national Call Before You Dig center will notify National Grid and other participating utilities, allowing us to mark our underground wires, pipes or cables so you'll know what areas to avoid.

We'll mark the appropriate areas according to this easy to follow color-coded system.



Then you'll be ready to dig safely! Be sure to dig around the markings and not on them. Safe digging keeps you, your family and friends secure and protected.
