Natural gas pipelines and other utilities run under streets and sidewalks as well as under yards. Digging into these lines could disrupt gas service to the neighbourhood. Even minor damage to a gas pipeline or its coating (such as a gouge, scrape, or dent) could harm the integrity of the pipeline and cause a future break or leak. Accidentally digging into underground power lines could cause an electrical shock hazard and disrupt electrical service in the neighbourhood. Damage could even result in electrocution.
Your utility locator center, reached by dialing 811, makes sure underground natural gas pipelines 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!
