Full Breakdown
Section 9.405D of the Village Code, in the Prohibited Acts section of the water chapter, makes it unlawful for any user of village water having knowledge of a leak in the water system on his premises to fail to take prompt action to stop or repair it. The code does not set a number of days. The standard is prompt action and due diligence, and it applies to all water consumers of the village, who must exercise due diligence to prevent waste of the water supply while correcting all leaks on their property.
The enforcement step is built into the same sentence. If a leak on private premises is not promptly stopped or repaired, the code declares the situation an emergency, and the director of public works is authorized to take immediate steps to shut off the water supply to that property until the leak has been corrected. No prior hearing is written into the provision.
Responsibility for the pipe is set by section 9.408B: all repairs of water service pipes of buildings are made by and at the expense of the owners of the premises served, covering the service pipe on the property owner's side of the B-box. In an emergency the village can repair any service pipe, and if it does, the owner of the premises repays the cost.
Related rules sit beside the leak duty. Section 9.405B makes it unlawful for anyone not authorized by the village to tamper with, alter or injure the village water system or water meters, and section 9.405E makes anyone who damages a village water main or vault responsible for repair costs and for damage to surrounding properties.
Violations & Fines
Failing to act on a known leak violates section 9.405D, and the practical consequence is the shutoff of water service by the director of public works until the leak is corrected. Section 9.407 sets a citation procedure: an official can issue a citation asking for settlement in the amounts listed in appendix A, division III, and if the person does not settle, a complaint is filed in the circuit court of Cook County.
