Lead pipes in Jefferson County, Wisconsin

Who pays in Wisconsin

Wisconsin lets each utility decide. Under a 2017 law, utilities can offer grants or loans to owners for the private side with Public Service Commission approval. The DNR gives municipalities principal forgiveness (money that does not have to be repaid) for private-side work, and since July 2025 state law also allows forgiving loans for lead line projects. Homeowners cannot apply to the DNR directly; the money flows through the city.
