Who pays in Michigan
Michigan has the strongest lead line rule in the country. Since the 2018 revision after the Flint crisis, water suppliers must replace all lead service lines, including the part on private property, by 2041, and they pay for it from system revenue rather than billing the owner directly. Partial replacements are banned except in emergencies. Water suppliers challenged the rule, and the Michigan Court of Claims upheld it in 2019.
