When doing projects around your house, digging without knowing where underground utility lines are buried can be very risky. Any time underground lines are damaged, vital services and everyday conveniences can become disconnected, not only to your home but to entire neighborhoods and, sometimes, whole subdivisions. Don't risk harming yourself, your family or your neighbors.
When planning an excavation project, simply dial 811 at least 48 hours (two working days) before you plan to start your work. They will notify underground utility providers, who will send professional locators out to mark the approximate location of their utility lines. If you prefer to, get computer notifications.
Then you can dig confidently, knowing the utilities will not be disturbed. The call is simple, free and it's the law!
