Frequently Asked Questions



Water Sources



The Kaua`i Department of Water is committed to providing safe, affordable, dependable drinking water service for our customers every day.   In compliance with the Safe Drinking Water Act, a federal law, the Kaua`i Department of Water produces and provides a water quality report for our customers each year.  The report describes the quality of your drinking water, and where it comes from.


Providing safe drinking water is a complex process, but you have a right to know the results of our water quality monitoring. Safe drinking water is essential to our community. Your water is tested on a continuous schedule through our certified laboratories and the State Department of Health.



In summary, our drinking water meets, or is better than, state and federal standards.


A Source Water Assessment, intended to enable “well-founded, fair and reasonable decisions for the protection and preservation of Hawai‘i’s drinking water” has been completed by the State Department of Health and the University of Hawai‘i.
