Who pays in California
This state has no law we found that decides who pays for the private side of a lead service line, so each utility sets its own policy. Under the federal rule, utilities must replace every lead line and galvanized line that needs it within ten years of November 1, 2027, but the rule does not make utilities pay for the owner's side. Federal infrastructure money passed through the state revolving fund can pay for it, so many utilities offer free or discounted replacement, especially for low-income owners.
