Lead pipe replacement law in Iowa
Iowa has not set its own state-specific lead service line replacement deadline beyond the federal requirement below. The rule is implemented through the Iowa Department of Natural Resources, which required every public water system to submit an initial inventory by October 16, 2024, with an updated baseline inventory due by the federal Lead and Copper Rule Improvements' November 1, 2027 compliance date, rather than setting an earlier state-specific replacement date.
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.
