Lead Pipe Replacement Grants and Funding in Idaho

If you're facing the cost of replacing a lead service line, Idaho has several funding programs designed to help homeowners. Here's what's available and how to access it.

Federal Infrastructure Funding

The Bipartisan Infrastructure Law (BIL) allocated federal money to states for lead service line replacement. Idaho received infrastructure funding to support water system upgrades, though direct homeowner rebates vary by utility. Your best move is to contact your local water utility to ask if they've received BIL funding and whether homeowners can apply for grants or low-interest loans to cover replacement costs.

Idaho's Drinking Water State Revolving Fund (DWSRF)

Idaho's DWSRF is a federal-state loan program that finances water infrastructure projects, including lead line removal. Water systems serving disadvantaged communities receive priority funding. If your utility is applying for these loans, some of that money may be passed to homeowners as grants or forgiven loans—but this depends on your utility's specific program design.

Key point: Not all utilities have homeowner replacement programs yet. Even if your system received DWSRF funds, they may prioritize replacing lead lines on public property (main lines) first, then move to service lines on private property.

How to Find Out What You're Eligible For

1. Identify your water utility by address (your water bill will show this). 2. Call and ask directly: - "Have you received BIL or DWSRF funding for lead service line replacement?" - "Do you offer grants, loans, or reimbursement to homeowners replacing lead lines?" - "What's the cost to replace a service line, and what are my payment options?"

3. Ask about income-based assistance. Some utilities prioritize low-income households for free or subsidized replacement.

What If Your Utility Hasn't Started Yet?

Many Idaho water systems are still planning their lead removal timelines. Federal law (the Lead and Copper Rule) requires utilities to replace lead lines on a schedule—most have deadlines between 2024 and 2027. Utilities are required to keep a lead service line inventory; you can ask to see yours.

Protecting Your Health While You Wait

If you haven't had your line replaced:

  • Use a certified lead filter on your kitchen tap if your water tests positive for lead (ask your utility for a free test kit).
  • Flush your lines before drinking (run water for 30 seconds to 2 minutes, depending on how long it's been sitting).
  • Talk to your pediatrician if you have young children—they're more sensitive to lead exposure.

Next Steps for Residents

  • Contact your water utility and ask specifically about lead line replacement funding available to homeowners.
  • Request a free water quality test to check for lead in your home.
  • If income-qualified, ask whether your utility offers cost assistance programs.
  • Keep records of any communication about funding timelines and eligibility.

Common questions

Does Idaho have a homeowner grant program for lead pipe replacement?

Funding varies by water utility, not statewide. Some Idaho utilities offer grants or low-interest loans through federal DWSRF or BIL programs, but you must contact your specific water provider to learn about their program. Ask whether they prioritize low-income households.

How much does it cost to replace a lead service line in Idaho?

Replacement costs typically range from $3,000 to $8,000+, depending on line length and soil conditions. Your water utility can provide a site-specific estimate. Many utilities offer payment plans or assistance for eligible homeowners.

What is the Bipartisan Infrastructure Law and does it help Idaho homeowners?

BIL is federal funding for water infrastructure, including lead line replacement. Idaho received allocation, but funds flow through water utilities, not directly to homeowners. Ask your utility whether BIL money is available for homeowner replacement assistance.

How do I know if I have a lead service line?

Your water utility keeps a lead service line inventory and can tell you whether your property has one. Request a free water quality test from your utility—if lead is present, a lead line is a likely source. A plumber can also inspect your line visually.
