WAIALUA-HALEIWA Water System Lead Service Line Inventory
About This Water System
WAIALUA-HALEIWA serves approximately 9,996 people in Hawaii. The system draws from groundwater sources.
Lead Service Line Inventory Status
As of now, this water system has not yet completed a lead service line (LSL) inventory—meaning the utility has not finished documenting which pipes in the distribution network are made of lead. This is a required step under the EPA's Lead and Copper Rule Revisions, but many smaller systems across the US are still in progress.
What this means for you: Without a completed inventory, the utility doesn't have public documentation of which service lines in the system are lead. This doesn't necessarily mean your water is unsafe—most lead exposure happens at the connection between the main pipe and your home, and at internal household plumbing. But you won't know from this official inventory whether your service line is lead or not.
What You Can Do Now
Contact your water utility directly. Call or visit the WAIALUA-HALEIWA water department and ask:
- Whether your specific address has a known lead service line
- What testing they recommend for your household water
- When they expect to complete their full inventory
Get your water tested. Even if your service line status is unknown, you can have your tap water tested for lead. The EPA recommends testing if your home was built before 1986 or if you have young children or pregnant household members. Your local health department can often recommend certified labs.
Check your home's age and plumbing. Homes built before 1986 are more likely to have lead service lines or lead solder in internal pipes. If you know your home's construction date, that information is useful to have when you call your utility.
Funding and Replacement Plans
We don't currently have information about whether this system has received federal funding for LSL replacement or details on any planned replacement timeline. Ask your utility directly about these programs—funding and grants may be available to help with replacement costs.

Frequently asked
Does WAIALUA-HALEIWA have lead in the water?

How do I find out if my house has a lead service line?
Contact WAIALUA-HALEIWA water utility directly with your address and ask. They should have records of service line materials, even if their full inventory isn't public yet. You can also hire a plumber to inspect your home's internal plumbing.
Is it safe to drink tap water from WAIALUA-HALEIWA?
The utility is required to monitor water quality and follow EPA safety standards. If you have concerns about lead specifically, get your water tested and talk to your pediatrician if you have young children.

The utility has not yet published a public replacement plan or timeline. Contact them directly to ask about their plans and any grants or assistance programs available to help with replacement costs.
