What is the Lead Service Line Replacement Cost Calculator®?

Replacing lead service lines (LSLs) across the United States will deliver major public health benefits but also comes with significant costs, potentially exceeding $100 billion, according to the American Water Works Association.

To support nationwide efforts to replace millions of lead service lines and advance climate-resilient drinking water infrastructure, the Lead Service Line Replacement Cost Calculator® (LSLRCC) was developed to provide Tribal governments, municipalities, utilities, and other government agencies with precise, data-driven project cost modeling that supports compliance with EPA’s Lead and Copper Rule Improvements (LCRI).

Developed under the leadership of former EPA Flint Emergency Coordinator Anthony Ross, the LSLRCC empowers Tribal governments, municipalities, and utilities to plan and fund equitable and climate-resilient drinking water infrastructure replacements that reduce lead exposure, improve efficiency, and protect public health nationwide.

Advancing Climate-Resilient Drinking Water Infrastructure

Climate-resilient drinking water infrastructure refers to drinking water systems that are intentionally designed, built, and managed to adapt to and withstand climate change impacts such as flooding, drought, extreme heat, and other weather events that can stress or damage pipe networks and increase lead leaching risk.

Integrating resilience into lead service line replacement ensures that drinking water infrastructure investments remain durable, equitable, and protective of public health in a changing climate.

Tribal and Local Governments Can Save Millions on Lead Service Line Replacements

A Tribal government or city planning to replace a substantial number of lead service lines can use the LSLRCC to precisely model project costs. By inputting local data such as material costs, labor rates, and project size, planners can uncover cost-effective strategies that also strengthen long-term, climate-resilient drinking water infrastructure.

The tool helps model different scenarios, identifying opportunities to bundle projects, optimize resources, and select the most efficient replacement methods. This data-driven planning helps prevent costly overruns, saves millions, and accelerates LSLR progress to better protect public health.

How to Use This Tool to Model and Estimate Lead Service Line Replacement Costs

• Decide your scope: You can calculate costs for one project or multiple projects—use the inputs to model different scenarios as needed. For example, you can run various cost scenarios for full or partial replacements.
  
  
• Enter whole numbers: For counts and costs (e.g., 105 — not 105.15).
  
  
• Customize inputs: Include local data such as the number of service lines, material costs, excavation costs, labor costs, administrative costs, contingency costs, and post-replacement costs.
  
  
• Use tooltips: Hover over or tap each input for guidance on what to enter and why.
  
  
• Review your results: See total and average costs immediately to help plan budgets or proposals.
  
  
• Run multiple scenarios: Adjust inputs to compare different approaches, funding options, or project sizes.
  
  
• Note: Results are based on your estimates and intended for planning purposes only. See Terms and Conditions.
