HAINA Lead Service Line Inventory
About your water system
HAINA serves 4,563 people on Hawaii's Big Island. The utility draws water from groundwater sources. This page covers what is publicly known about lead service lines—the pipes that connect the public water main to individual homes—in HAINA's service area.
What we know (and don't know)
As of now, HAINA has not published a detailed lead service line inventory. That means the utility hasn't yet released a public count of how many lead service lines exist in its system, or whether replacement work is underway.
The U.S. Environmental Protection Agency (EPA) requires all water utilities to complete an inventory of lead service lines by October 2024 and to develop a plan for replacing them. If HAINA has completed this work but the data isn't yet posted here, contact the utility directly—they're required by law to share this information with customers.
Why this matters
Lead service lines can leach lead into drinking water, especially in homes with older plumbing or where water chemistry favors corrosion. Even low levels of lead exposure over time can affect child development and adult health. The only way to fully eliminate this risk is to replace the service line with a non-lead alternative (usually copper or plastic).
What you can do now
Contact HAINA to ask:
- Has the utility completed its lead service line inventory?
- Is my address on the list of known or suspected lead service lines?
- What replacement programs or funding are available?
Test your water if you're concerned. A water test won't tell you definitively whether your service line is lead, but it will show whether lead is present in your tap water right now. Contact your local health department or HAINA for affordable testing options.
Reduce lead exposure while you wait. Run cold water for 30 seconds before drinking or cooking if the tap hasn't been used in several hours. Don't boil water to remove lead—boiling concentrates it. For questions about health risks, contact your pediatrician or the CDC.
Next steps for residents
- Contact HAINA to request your service line status and ask about replacement assistance.
- Request a free or low-cost water lead test from the utility or your state health department.
- If your service line is confirmed lead or unknown, ask HAINA about replacement programs, grants, or payment plans.
- Check your homeowner's insurance or local government programs—some offer financial help for lead service line replacement.

Frequently asked
How do I know if my water has lead?
The only way to know for sure is to test your water. Contact HAINA or your county health department to request a free or low-cost lead test. A test shows whether lead is in your tap water now, but not whether your service line is made of lead.
Can I remove lead from my water myself?
Boiling doesn't work—it actually concentrates lead. Point-of-use filters (like faucet-mounted or pitcher filters) certified for lead removal can help, but replacing the service line is the only permanent solution. Check NSF International certification to make sure any filter works for lead.
Is lead in water dangerous for kids?
Yes, lead exposure during childhood can affect brain development and learning. The CDC and pediatricians recommend testing water in homes with young children, especially if the home is older than 1986. Talk to your child's doctor if you're concerned.
How much does it cost to replace a lead service line?
Costs vary widely but typically range from $3,000 to $25,000+ depending on line length and soil conditions. Ask HAINA about rebates, grants, or low-interest loans—many utilities now offer financial assistance for replacement.
