Lead pipe replacement law in Indiana

Indiana has not set its own state-specific lead service line replacement deadline beyond the federal requirement below, but a separate 2024 state law changes what utilities are allowed to do about it: Senate Bill 5 (Public Law 6-2024, signed March 11, 2024) authorizes a water utility to enter a property and replace the customer-owned portion of a lead service line — even if the owner hasn't enrolled in the replacement program or responded to outreach — and shields the utility from liability for doing so. The rule itself is implemented through the Indiana Department of Environmental Management, which required every public water system to submit a baseline inventory by October 16, 2024.

Separately from any state law, the EPA's federal Lead and Copper Rule Improvements require every water system nationwide to submit a baseline inventory and an approved replacement plan by November 1, 2027, then fully replace all lead and "galvanized requiring replacement" lines under its control on a schedule of 10 years or less from that date, replacing at least 10% of its known lead/GRR lines per year. A narrow exception allows a longer schedule only for the roughly 1% of systems with an unusually dense concentration of lead lines, and partial (non-emergency) replacements are prohibited.
