Water Quality Reports

Frequently Asked Questions



Water Sources


This Customer Confidence Report (CCR), is produced by the Kauaʻi Department of Water and describes the quality of your drinking water and where it comes from.


Providing safe drinking water is essential to our communities and it is important that our customers are informed that your water is tested on a continuous schedule through our certified laboratories and the State Department of Health.


Based on our test results, we are pleased to report that Kauaʻi's potable water supply meets or exceeds state and federal standards for clean, safe drinking water.


A Source Water Assessment, intended to enable “well-founded, fair and reasonable decisions for the protection and preservation of Hawaiʻi’s drinking water” has been completed by the State Department of Health and the University of Hawaiʻi.  For further information on this assessment, please contact the Department of Water at (808)245-5455.


We welcome your interest in the Department of Water’s water systems.  Please refer to the directory in this report for the Department’s contact numbers.  The Board of Water Supply holds a monthly meeting on the third Thursday of each month and meetings are open to the public.  Please call (808) 245-5406 or visit our website at for scheduled meeting information.
