Contact the Indiana Underground Plant Protection Service (I.U.P.P.S.) when digging along the borders of Chicago and Indiana to notify utilities of impending excavations.
Digger is a twenty-four hour service network system established to prevent contractors and private citizens from hitting any existing utility line(s) when digging.
Requests for Dig Notices must be accepted by Chicago's Digger operation at least 48 workday hours before digging can begin, as mandated by Illinois state law.
