Lead service line replacement cost calculator (LSLRCC) tool

A free, multilingual planning tool advancing safe drinking water, equity, and climate-health resilience

The Lead Service Line Replacement Cost Calculator (LSLRCC) is a free, multilingual tool developed to help Tribal and local governments plan and estimate the cost of replacing lead service lines. The tool supports the national effort to replace 9.2 million lead service lines across the United States and assists utilities in complying with EPA’s Lead and Copper Rule Improvements (LCRI), while advancing climate-resilient drinking water infrastructure.

Lead exposure remains a serious public health threat, contributing to developmental delays, cardiovascular disease, kidney damage, and reproductive harm, with disproportionate impacts on vulnerable and underserved populations.

The LSLRCC was created to fill a critical resource gap for historically disadvantaged and under-resourced communities. It has already been used to model billions of dollars in replacement costs based on anonymous website analytics, helping localities make informed, data-driven infrastructure decisions.

By reducing economic and technical barriers, the LSLRCC empowers communities to address one of the most persistent environmental health challenges of our time.

Recognized by the United Nations Environment Programme (UNEP), UNESCO, and the UN Global Compact Water Action Hub, the LSLRCC advances equitable access to safe drinking water, strengthens climate and health resilience, and supports multiple UN Sustainable Development Goals (SDGs 3, 6, 11, 13, and 17).
