MAKAWAO is among the 10 largest community water systems in Hawaii, serving 29,868 people from surface water.
As of August 1, 2026, its federal record holds 21 entries between 1987 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
Of the 21, 10 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Surface Water Treatment Rules, synthetic organic chemicals, and the Total Coliform Rules.

Common questions
Is MAKAWAO required to publish a Consumer Confidence Report?
- Yes. MAKAWAO is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is MAKAWAO’s next Consumer Confidence Report due?
- MAKAWAO’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MAKAWAO have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for MAKAWAO.
What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
