Lead Service Lines in Lahaina

Lahaina water system serves roughly 20,000 people on Maui. If you're concerned about lead in your drinking water, here's what you need to know about your utility's lead service line inventory.

What is a lead service line?

A lead service line is the pipe that connects your home to the water main under the street. Many homes built before 1986—especially those constructed before the 1950s—have lead pipes in this connection. Lead can leach into drinking water, particularly if the water is corrosive or sits in the pipes for several hours.

What does Lahaina's inventory show?

Lahaina has not yet completed a public inventory of lead service lines in its system. The utility has not published data on how many lead, galvanized, or non-lead pipes serve the community. This is not unusual—many water systems are still in the process of mapping their infrastructure, which can be time-consuming and expensive.

How to find out about your home

Your best next step is to contact Lahaina water directly and ask:

• Does your service line contain lead?
• If they don't know, ask how you can help them identify it (some utilities offer free inspections or visual surveys).
• Request information about any corrosion control measures they use to reduce lead leaching.

You can also:

• Check your home's age and construction records. Homes built before 1986 are higher-risk.
• Have your water tested for lead by an EPA-certified lab. The EPA recommends this, especially if you have young children or are pregnant.

If you find lead

Lahaina should have a plan to replace lead service lines over time. Ask your utility about their replacement timeline and whether you're eligible for assistance. Some utilities cover replacement costs for low-income households.

For health questions—especially if you have children under 6 or are pregnant—contact your pediatrician or the CDC's lead information line.

Next steps for residents

• Contact Lahaina water to ask about your service line status and corrosion control practices.
• Get your water tested through an EPA-certified lab if you're concerned; tests typically cost $20–$50.
• Check your home's age; if built before 1986, assume higher risk until you know otherwise.
• Ask about replacement assistance if lead is confirmed.

Does Lahaina water have lead service lines?

Lahaina has not yet published a complete inventory of lead service lines in the system. Contact the utility directly to ask about your specific address or to learn about their mapping progress.

How do I know if my house has a lead service line?

Call Lahaina water and ask them to check your address. Homes built before 1986 are at higher risk. You can also hire a plumber to inspect the line where it enters your home.

Is lead in Lahaina's water dangerous?

Lead can leach into water from lead pipes, especially in young children, pregnant people, and developing fetuses. Talk to your doctor or pediatrician about your risk. The CDC has guidelines on testing and protection.

What should I do if my water tests positive for lead?

Use bottled water for drinking and cooking until the problem is fixed. Contact Lahaina water about service line replacement options and ask about financial assistance programs. See a doctor about testing your child's blood lead level.
