WAILUKU Water System Lead Service Line Inventory
About this water system
Wailuku Water System serves approximately 74,511 people in Hawaii. The system draws from surface water sources.
Lead service line inventory status
As of now, Wailuku has not yet inventoried its lead service lines. This means the water utility has not yet completed a public count of how many service lines (the pipes connecting the water main to homes) contain lead.
Under the revised Lead and Copper Rule, all US water systems must complete a full inventory of lead service lines by October 2024. If your water utility has not yet published an inventory, you can contact them directly to ask about their progress and timeline.
What this means for your home
Not having a published inventory doesn't mean there are no lead service lines in your area—it means the utility is still gathering that data. Many older homes across the US do have lead service lines, especially in areas built before 1980.
The most reliable way to find out if your home has a lead service line is to:
1. Contact your water utility and provide your address. They may have records or be able to conduct a visual inspection. 2. Check your home's age and construction records. Homes built before the 1970s are more likely to have lead service lines. 3. Get a water test. A certified lab can test your tap water for lead. Results will tell you if lead is present in your water right now—regardless of pipe material.
Lead in water is a health concern, particularly for young children and pregnant people. If you have concerns about your family's exposure, talk to your pediatrician or contact the CDC.
