What is JULIE?Also known as the Illinois One-Call System, JULIE is a free message service for homeowners and contractors to notify utility owners of planned digging activities to help prevent damage to underground facilities.
What Happens After the Call?Within two (2) working days from your call, representatives from each member utility, (not JULIE employees), will come out and mark the approximate location of their buried lines using the following color code. JULIE requests are valid for 28 days so flags and markings should not be removed before that time if work is not totally complete.
Utility Marking ColorsAccording to Illinois state law section 10, each utility company must use a specific color paint or flag to mark their buried facilities.
