Utilities Protection Center

A new federally mandated “call before you dig” three digit number, 811, has been launched to provide ease in contacting your local Utilities Protection Center. This new number will route you to one of the 62 One Call centers located in the U.S. based on the area in which you are dialing from. By placing this call, it will notify the appropriate utility companies in your area to send out location technicians to your area of proposed excavation to mark underground utility lines. Excavation includes many things such as planting a tree, digging a hole for your mailbox, installing a pond, basically anything that requires digging. The call to 811 and the service are free. At least 72 hours prior to beginning your digging project, call 811; it’s the law and it could protect you from injury and costly repairs should you dig into an underground utility line.
