Notify Pennsylvania One Call at 8-1-1 at least three business days before you start a project that involves digging. PA One Call will notify your local utility companies to come out and mark the location of their lines. That way you can avoid injury, repair costs, fines and inconvenient service outages. There is no cost to use the service. Visit www.pa811.org or www.pa1call.org for more information about digging safely.
