Lead And Copper Rule Improvements (LCRI) Timeline

The regulatory landscape for water systems has shifted with the implementation of the Lead and Copper Rule Improvements (LCRI). Systems must now manage a rigorous multi-year schedule that begins with the submission of a comprehensive service line inventory and, where necessary, a publicly accessible replacement plan. By the late 2027 compliance date, utilities are required to transition into an active notification phase, alerting residents of lead or unknown lines within 30 days of inventory submission and annually thereafter.

Review the full LCRI timeline to ensure your system meets every critical milestone.
