WAIPAHU-EWA-WAIANAE Water System Lead Service Lines
What you need to know
WAIPAHU-EWA-WAIANAE serves approximately 217,479 people across parts of Oahu, Hawaii. The utility draws from groundwater sources.
As of now, the water system has not yet completed a public inventory of lead service lines—the pipes that connect the main water line in the street to homes. Federal law requires all water systems to identify and inventory these lines by 2024. This does not mean your home definitely has a lead service line, but it does mean the utility is still in the process of determining how many exist in your area.
Why lead service lines matter
Lead service lines can leach lead into drinking water, especially in homes with naturally acidic water or water systems that haven't added corrosion control treatment. Even small amounts of lead exposure over time can affect health, particularly in children and pregnant people. Lead service lines are the most common source of lead in drinking water.
