WAIKOLOA Water System Lead Service Line Information
What you need to know
WAIKOLOA serves about 12,100 residents in Hawaii. Like all US water systems, WAIKOLOA is required by the EPA to identify and track lead service lines—the pipes that connect the public water main to individual homes.
Current inventory status: WAIKOLOA has not yet completed a lead service line inventory. This means the system is still in the process of determining which homes may have lead service lines.
Why this matters
Lead service lines can leach lead into drinking water, especially if water is corrosive or if pipes are old and corroded. Lead exposure, particularly for children under 6 and pregnant people, can cause serious health effects. Even low levels matter—there is no safe level of lead for children.
If your home was built before 1986, there's a higher chance your service line contains lead. However, homes built after that date can also have lead service lines in some cases.
What WAIKOLOA is doing
WAIKOLOA is required by the Lead and Copper Rule to complete a full inventory of all service lines and identify which ones contain lead. Until that inventory is complete, the utility should be able to tell you:
- When your home was built
- Whether your service line has been tested
- What treatment the water receives to reduce corrosion
What you can do now
Contact WAIKOLOA directly to ask about your specific address:
- Request information about your service line material
- Ask if your water has been tested for lead
- Find out the timeline for the full inventory completion
Test your water at home. You can buy an affordable lead test kit or ask WAIKOLOA if they offer free testing.
Reduce exposure while you wait:
- Run cold water for 30 seconds before drinking or cooking if water has been sitting in pipes
- Use cold water for drinking and cooking (hot water leaches lead faster)
- Clean aerators on faucets regularly
If you have young children or are pregnant, contact your pediatrician or doctor about whether additional precautions make sense for your household.
Next steps for residents
- Call or visit WAIKOLOA's website to request your service line information
- Ask about lead testing availability in your area
- Consider a home water test if you're concerned
- Check back periodically—inventory completion timelines vary by system

Frequently asked
Does WAIKOLOA have lead in the water?
WAIKOLOA is still completing its lead service line inventory, so a full picture isn't available yet. Whether lead reaches your tap depends on your service line material, water chemistry, and pipe condition. Contact the utility to learn about your specific address.
How do I know if my house has a lead service line?
Ask WAIKOLOA directly—they can often tell you based on your address and construction records. You can also hire a plumber to check, or look where the service line enters your home (lead is soft, dull gray, and can be scratched with a coin).
Is it safe to drink tap water from WAIKOLOA?
WAIKOLOA treats its water to meet EPA safety standards. If you're concerned about lead specifically, run water for 30 seconds before drinking, use cold water for consumption, and consider testing your tap water.
When will WAIKOLOA finish its lead service line inventory?
The completion timeline depends on system size and resources. Contact WAIKOLOA directly for an estimated date, as this information isn't publicly available yet.
