KALUAKOI is one of 42 community water systems in Hawaii in the 501 to 3,300 people size category, formerly serving 700 people from groundwater.

EPA's federal records list this system as inactive in 2009; the record below is historical.

As of August 1, 2026, its federal record holds 8 entries between 1981 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.

None of the 8 are monitoring or reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset; these involve water-quality, treatment, or public-notice findings instead. The record involves the Surface Water Treatment Rules and the Total Coliform Rules.
