Call Before You Dig

Whether you’re a homeowner planting a tree or a contractor excavating a subdivision, you must call 811 before you dig. It’s free, it’s easy, and it’s the law.

Call 811 at least two days before you want to dig. Your state-run service will contact all your utilities, including electric, gas/petroleum, water, sewer, phone and cable for you at no charge to you. Your local utilities, including us, will mark the approximate location of all the buried lines in the area with color-coded paint or flags. All for free.

Call 811 before you dig. It’s free, it’s easy, and it’s the law.
