Underground power lines and other utilities run under streets and sidewalks as well as under yards and homes. Accidentally digging into these lines could cause an electrical shock hazard and disrupt electrical service in the neighbourhood. Damage to an underground power line could even result in electrocution.
Your utility locator center, reached by dialing 811, makes sure underground power lines and other utilities are clearly marked so people can dig a safe distance away from them. Whether you are planning to do it yourself or hire a professional, call 811 several days before digging begins. Any job requires a call, even planting a tree!
