All non-emergency penetration/excavation requires a forty-eight (48) hour minimum prior notice (excluding Saturdays, Sundays, and holidays) to the Chicago Utility Alert Network (Digger) 312-744-7000. Digger is a twenty-four (24) hour service network system established to prevent contractors and private citizens from hitting any existing utility line(s) when digging. Those interested in digging in Chicago, must first call Digger and provide information that will be transmitted electronically to all participating utility members.

The One-Call System does not mark utilities. The One-Call system only notifies participating member utilities. These participating member utilities will not mark private or non-member utilities. The utility locating companies notified will locate and mark only primary public utilities, so it's up to you to keep track of what else is on your own property.

Private Utilities are the buried lines after the meter or main lines. If you have a curbside meter then your property will not get marked by the participating member utility locators. Other buried utilities that generally are not marked include but may not be limited to: sewer lines, private lighting, sprinklers, fire mains, secondary electric lines to detached garages, and septic lines.
