This Sunday, August 11, serves as a natural reminder for customers and contractors to call 811 before digging to have underground utility lines marked. Nationwide, every eight minutes an underground utility line is damaged because someone decided to dig without first calling 811. Striking an underground electric or natural gas line can cause serious injury, damages and service interruptions. Every digging project, no matter how large or small, warrants a call to 811. Installing a mailbox, building a deck, planting a tree and laying a patio are all examples of digging projects where a call to 811 should be one of the first steps. PECO has underground electric and natural gas lines throughout the region. And, there may be an electric or natural gas line in front of your property. For this reason, even if you do not have natural gas service in your home, you should be aware of what lines are underground. When calling 811, homeowners and contractors are connected to PA One Call to provide information about their project. PA One Call will notify all member utilities of your plan to dig. The utilities will then mark the underground facilities. Calls are required at least three days in advance. PECO operates nearly 9,000 miles of underground primary electric lines, 12,000 miles of natural gas distribution and service lines, and 31 miles of natural gas transportation lines in our region.
