ALIAMANU Water System: Lead Service Lines
About this water system
ALIAMANU serves 6,406 people in Hawaii. The system draws from groundwater sources.
Lead service line inventory status
ALIAMANU has not yet completed a lead service line inventory. This means the utility has not yet surveyed and documented which homes are connected to the water main with lead pipes.
Federal law requires all water systems to complete an initial inventory of lead service lines by October 2024. If your water system has not finished this work, it should be underway or recently completed.
What this means for you: You may not know yet whether your home has a lead service line. Even without a full inventory, you can take steps to protect your household.
What you can do right now
Contact ALIAMANU directly to ask:
- Whether your specific address has a known lead service line
- When the inventory will be available to the public
- Whether the utility offers free water testing or lead treatment
Don't wait for the inventory. If your home was built before 1986, it's more likely to have lead pipes. Consider:
- Having your water tested for lead (many health departments offer this free or low-cost)
- Installing a certified lead filter on your kitchen tap
- Letting cold water run for 30 seconds before drinking or cooking if your pipes haven't been used for several hours
If you have young children or are pregnant, talk to your pediatrician or OB/GYN about lead exposure risk in your area.
Why this matters
Lead in drinking water comes from corrosion of old pipes and plumbing. Even small amounts can affect child development. The CDC recommends that anyone concerned about lead in their water take action.

Frequently asked
Does ALIAMANU have lead service lines?
ALIAMANU has not yet completed its lead service line inventory, so the full picture is not yet public. Contact the utility directly or check their website for updates on when the inventory will be available.
How do I know if my house has a lead pipe?
Contact ALIAMANU with your address to ask if your service line is documented as lead. You can also have a plumber inspect, or get your water tested—a high lead reading suggests a lead service line.
Is lead in water dangerous?
Yes. Lead in drinking water is especially risky for young children and pregnant people. Even low levels can affect development. The CDC recommends testing if you're concerned and using filters or flushing pipes as interim steps.
What should I do if I'm worried about lead in my water?
Get your water tested, use a certified lead filter on your tap, and talk to your doctor if anyone in your household is pregnant or under age 6. Then contact ALIAMANU to find out your service line status.
