Aug. 11 (8/11) is National Call Before You Dig Day
CHICAGO (Aug. 9, 2018) – With the safety of customers and employees as its top priority, ComEd is letting homeowners, businesses, and contractors know that Aug. 11 (8/11) is National Call Before You Dig Day – an annual reminder to call 811 before digging to have utility-owned underground lines marked.
Someone damages an underground utility line every six minutes in the United States by digging without first calling 811, according to the Common Ground Alliance, the national association that promotes the 811 phone number and safe digging practices. Striking an underground electric line can cause serious injury, damages and service interruptions.
People should call 811 before any digging project, such as installing a mailbox, building a deck, planting a tree or laying a patio. Customers and contractors also are required to call 811 before clearing blocked sewer lines to determine if any utility lines are nearby as well.
ComEd manages nearly 21,000 miles of underground electric lines, many of which cross residential properties. Properly locating these lines is essential to safely completing a digging job. In addition to ComEd's lines, there are underground communications cables, water and sewer lines and other utilities. Even properties that are not served by a particular service may have utility lines running below them.
When customers and contractors call 811, they are connected to either Joint Utility Locating Information for Excavators (JULIE) for Illinois suburban areas or Digger for the city of Chicago, to provide information about their project. JULIE or Digger notifies all member utilities, which then mark the underground facilities. Calls are required at least three days in advance.
Customers and contractors must understand the line markings and look for evidence of unmarked lines, such as water and sewer lines on private property. Sewer clean-outs and water valve covers are examples of equipment that can indicate the presence of underground lines.
ComEd joins the Exelon family of companies in recognizing National Call Before You Dig Day. As a member of the Common Ground Alliance, ComEd shares best practices to promote safe excavation and decrease damage to underground lines. The company also provides families and businesses important information about safety around overhead and underground electric lines through mailings, customer newsletters, social media and advertising.
