Lead Pipe Replacement Grants and Funding in Hawaii

Understanding your options

If you have a lead service line in Hawaii, replacing it costs money—but you may not have to pay for it alone. Federal and state programs exist to help homeowners cover replacement costs, with priority often going to low-income households and historically underserved communities.

Federal funding: Bipartisan Infrastructure Law

Hawaii's water systems are eligible for federal grants and low-interest loans through the Drinking Water State Revolving Fund (DWSRF), which was bolstered by the 2021 Bipartisan Infrastructure Law. However, specific dollar amounts allocated to Hawaii's DWSRF for lead service line replacement have not been announced publicly in recent guidance.

The DWSRF typically funds water system improvements rather than individual homeowner replacements directly. Your local water utility applies for these grants, then uses them to replace lead lines in their service area—sometimes at no cost to residents.

State programs and disadvantaged-community priority

Hawaii's DWSRF Intended Use Plan (IUP) sets aside funding for disadvantaged communities. Water systems serving low-income areas receive preference for loans and grants. If your household qualifies as low-income under federal poverty guidelines, you may be eligible for additional assistance when your utility launches a replacement program.

Currently, Hawaii does not have a separate state-level homeowner reimbursement program for lead line replacement. Your primary route is through your water utility's replacement initiative, which may be grant-funded.

What to do now

Contact your local water utility directly. Ask:

  • Does our system have a lead service line replacement program?
  • Am I eligible based on income or neighborhood?
  • What is the timeline, and what is my cost share (if any)?

Large water systems serving Honolulu and other major areas are more likely to have active programs. Smaller rural systems may be earlier in planning.

Next steps for residents

  • Contact your water utility and ask about lead line replacement programs and grants they've received
  • Check your household income against federal poverty guidelines (visit aspe.hhs.gov) to see if you qualify for low-income assistance
  • Request a water quality test if you're unsure whether your home has a lead service line
  • Visit the EPA's Safe Drinking Water Act page for updates on national lead replacement funding initiatives

Common questions

Does Hawaii offer free lead pipe replacement for homeowners?

Not directly through a state homeowner program. However, if your water utility receives federal DWSRF grants for lead line replacement, you may be eligible for free or subsidized service. Contact your utility to ask if they have an active replacement program and whether your home qualifies based on income or location.

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

Costs vary widely depending on line length, soil conditions, and your location within the state. Typically $3,000–$10,000+. If your water utility's program is grant-funded, your out-of-pocket cost may be zero or significantly reduced.

Is my water system in Hawaii replacing lead pipes?

That depends on your specific utility. Call your local water department and ask whether they have received funding or have plans for lead service line replacement. Major systems serving urban areas are more likely to have active programs.

What if I can't afford to replace my lead pipe?

Ask your utility about income-based assistance, grant programs, and phased replacement schedules. If you cannot afford replacement now, using a NSF-certified water filter and flushing your tap before use can reduce lead exposure until replacement is possible. Contact your utility and a pediatrician for health guidance.
