Lead Service Line Replacement Survey

In January 2022, Illinois passed the Lead Service Line Replacement and Notification Act (LSLRNA). The first purpose of the LSLRNA requires owners and operators of community water supplies to deliver a complete water service line material inventory to the Illinois Environmental Protection Agency (EPA). 

To meet the requirements of the LSLRNA and identify lead service lines in our community, the City needs your assistance in performing a quick test to determine the water service line material on your property. We are therefore conducting this resident survey to inventory the water service material on the private side (resident owned).


Water and Sewer Services is responsible for the following:

  • Operating the Northwest and Southeast Wastewater Treatment Plants
  • Providing water quality reports
  • Supplying the City with fresh water

For water outages, sewer backup, or emergencies, please call the water and sewer hotline 24 hours a day.
