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.
