Lead pipe replacement law in South Dakota
South Dakota has not set its own state-specific lead service line replacement deadline beyond the federal requirement below. Replacement in South Dakota is governed by the state's own Lead and Copper Rule administrative regulations (South Dakota Administrative Rule 74:04:11), which implement the federal Lead and Copper Rule, and by the nationwide Lead and Copper Rule Improvements schedule.
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.
