Lead pipes in Winnebago County, Illinois

Free replacement program confirmed

Who pays in Illinois

Illinois was one of the first states to require full replacement of every lead service line. Each water supply must file a final replacement plan by April 15, 2027, then replace a set share of its lead lines every year, on a timeline of 15 to 50 years depending on how many it has. A utility may bill the owner for the private side only if it is not using state or federal money for that work, and an owner can sign a waiver to decline private-side replacement. Illinois EPA lends to water systems and forgives part of the loan in lower-income communities, which is why many Illinois programs are free.
