Knowing where your utility mains are located and how to operate them is key to household safety and can significantly decrease property damage during an emergency. Make sure every member of your household is familiar with the location of your main water, electric, and gas switches and valves and knows how to operate them.
JULIE - Joint Utility Locating Information for Excavators
JULIE serves as a notification service for underground utility facilities. By calling 811 (or 1-800-892-0123), contractors, excavators, homeowners, and others who may be digging can contact JULIE to notify all of the utilities: gas, electric and phone. It is then the responsibility of each utility to mark the location of its underground facilities at the excavation site. JULIE services the entire State of Illinois, with the exception of Chicago. If you are digging within the city limits of Chicago, please contact DIGGER.
