MCC Ch. 11-12 requires Chicago Department of Water Management to repair public-side leaks once reported and obligates property owners to fix private-side leaks promptly, with adjustment programs available for excessive metered consumption.
Chicago's water service is split at the b-box (buffalo box) curb shutoff. The city repairs leaks on the public main and the service line up to the b-box; property owners must repair private-side leaks from the b-box into the home. MCC 11-12-150 requires owners to fix detected leaks promptly, with the Department of Water Management able to issue notices and ultimately shut off service for non-repair. Residents report visible leaks, broken hydrants, and water main breaks via 311 or the Water Management call center. Metered customers experiencing high bills from concealed leaks may apply for a one-time leak adjustment after repair documentation.
Failure to repair private-side leaks after notice triggers shut-off of service and fines from $100 to $1,000 per day under MCC 11-12-590. Tampering with shut-off valves carries enhanced penalties up to $2,000 per offense.
