WAHIAWA Water System Lead Service Line Inventory

About This Water System

WAHIAWA serves approximately 23,348 people in Hawaii. The system draws its water from groundwater sources.

Lead Service Line Status

WAHIAWA has not yet completed a full inventory of lead service lines in its distribution system. The utility currently shows zero service lines inventoried in available records.

Under the EPA's Lead and Copper Rule Revision, all water systems must identify and document lead service lines by 2027. Many utilities across the US are still in early stages of this work—either conducting initial surveys, gathering historical records, or planning replacement programs.

What This Means for Your Home

If you live in WAHIAWA's service area and your home was built before 1986, there's a meaningful chance your service line (the pipe carrying water from the main to your house) contains lead. Lead service lines were common in older construction, and lead can leach into water, especially if your water is corrosive.

You don't need to wait for the utility's full inventory to take action. You can:

  • Request your home's service line material from WAHIAWA directly. They may have historical installation records.
  • Get a plumber's inspection if you want certainty. This typically costs $100–$200 and takes an hour or two.
  • Have your water tested by a certified lab. WAHIAWA can recommend local labs or you can find one through your state health department.

Lead in drinking water is a serious public health issue, especially for young children and pregnant women. If you have concerns about lead in your household water, talk to your pediatrician or contact the CDC's lead hotline (1-800-232-4636).

Next Steps for Residents

  • Contact WAHIAWA to ask whether they have records of your service line material and when they expect to complete their lead inventory.
  • Get your water tested if you suspect a lead service line or want peace of mind.
  • Consult a licensed plumber for a service line inspection if you need confirmation of pipe material.
  • Talk to your pediatrician if household members (especially children under 6) may have been exposed to lead in drinking water.

Frequently asked

Does WAHIAWA have lead in its water?

WAHIAWA has not yet published a full inventory of lead service lines. The presence of lead in drinking water depends on whether your home's service line is made of lead, not the water source itself. You can request records from the utility or have your water tested.

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

Ask WAHIAWA for service line records (they may have installation history). Hire a plumber for an inspection, or have your water tested by a certified lab. Homes built before 1986 are at higher risk.

Is lead in drinking water dangerous?

Yes. Lead can harm brain development in young children and cause health problems at any age. If you're concerned about exposure, contact your pediatrician or the CDC (1-800-232-4636).

When will WAHIAWA finish its lead service line inventory?

Federal rules require completion by 2027, but WAHIAWA has not yet reported an inventory or replacement plan. Contact the utility directly for their timeline.
