Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

415 ILCS 5/17.11

    (415 ILCS 5/17.11)
    Sec. 17.11. Lead in drinking water notifications and inventories.
    (a) The purpose of this Section is to require the owners and operators of community water systems to (i) create a comprehensive lead service line inventory; and (ii) provide notice to occupants of potentially affected residences of construction or repair work on water mains, lead service lines, or water meters.
    (b) For the purposes of this Section:
        "Community water system" has the meaning provided in
    
35 Ill. Adm. Code 611.101.
        "Potentially affected residence" means any residence
    
where water service is or may be temporarily interrupted or shut off by or on behalf of an owner or operator of a community water system because construction or repair work is to be performed by or on behalf of the owner or operator of a community water system on or affecting a water main, service line, or water meter.
        "Small system" has the meaning provided in 35 Ill.
    
Adm. Code 611.350.
    (c) The owner or operator of each community water system in the State shall develop a water distribution system material inventory that shall be submitted in written or electronic form to the Agency on an annual basis commencing on April 15, 2018 and continuing on each April 15 thereafter until the water distribution system material inventory is completed. In addition to meeting the requirements for water distribution system material inventories that are mandated by the United States Environmental Protection Agency, each water distribution system material inventory shall identify:
        (1) the total number of service lines within or
    
connected to the distribution system, including privately owned service lines;
        (2) the number of all known lead service lines within
    
or connected to the distribution system, including privately owned lead service lines; and
        (3) the number of the lead service lines that were
    
added to the inventory after the previous year's submission.
    Nothing in this subsection shall be construed to require that service lines be unearthed.
    (d) Beginning on January 1, 2018, when conducting routine inspections of community water systems as required under this Act, the Agency may conduct a separate audit to identify progress that the community water system has made toward completing the water distribution system material inventories required under subsection (c) of this Section.
    (e) The owner or operator of the community water system shall provide notice of construction or repair work on a water main service line, or water meter in accordance with the following requirements:
        (1) At least 14 days prior to beginning planned work
    
to repair or replace any water mains or lead service lines, the owner or operator of a community water system shall notify, through an individual written notice, each potentially affected residence of the planned work. In cases where a community water system must perform construction or repair work on an emergency basis or where such work is not scheduled at least 14 days prior to work taking place, the community water system shall notify each potentially affected residence as soon as reasonably possible. When work is to repair or replace a water meter, the notification shall be provided at the time the work is initiated.
        (2) Such notification shall include, at a minimum:
            (A) a warning that the work may result in
        
sediment, possibly containing lead, in the residence's water supply; and
            (B) information concerning best practices for
        
preventing the consumption of any lead in drinking water, including a recommendation to flush water lines during and after the completion of the repair or replacement work and to clean faucet aerator screens; and
            (C) information regarding the dangers of lead in
        
young children.
        (3) To the extent that the owner or operator of a
    
community water system serves a significant proportion of non-English speaking consumers, the notification must contain information in the appropriate languages regarding the importance of the notice, and it must contain a telephone number or address where a person served may contact the owner or operator of the community water system to obtain a translated copy of the notification or to request assistance in the appropriate language.
        (4) Notwithstanding anything to the contrary set
    
forth in this Section, to the extent that (a) notification is required for the entire community served by a community water system, (b) notification is required for construction or repairs occurring on an emergency basis, or (c) the community water system is a small system, publication notification, through a local media, social media or other similar means, may be utilized in lieu of an individual written notification.
        (5) If an owner or operator is required to provide an
    
individual written notification to a residence that is a multidwelling building, posting a written notification on the primary entrance way to the building shall be sufficient.
        (6) The notification requirements in this subsection
    
(e) do not apply to work performed on water mains that are used to transmit treated water between community water systems and have no service connections.
        (7) The owner or operator of a community water system
    
may seek a full or partial waiver of the requirements of this subsection from the Agency if (i) the community water system was originally constructed without lead, (ii) the residential structures were constructed under local building codes that categorically prohibited lead construction materials or the owner or operator of a community water system certifies that any residential structures requiring notification were constructed without lead, and (iii) no lead sediment is likely to be present within the community water system or residential structures. The owner or operator of a community water system may seek a time-limited or permanent waiver.
        (8) The owner and operator of a community water
    
system shall not be required to comply with this subsection (e) to the extent that the corresponding water distribution system material inventory has been completed that demonstrates the water distribution system does not contain any lead.
