Living in Hawaii is a dream — until you discover your home’s water comes from the sky, and nobody told you how to make sure it’s safe.
Thousands of homes across the Big Island, Maui, Kaua’i, and rural O’ahu rely on rainwater catchment systems instead of county water. That means your drinking water, your shower water, and the water your family cooks with is collected from your roof and stored in a tank on your property. Beautiful concept. But here’s the thing most buyers — and even some longtime owners — don’t realize: a simple test strip from the hardware store is NOT enough to know what’s really in your water.
In this video, we break down everything you need to know about water quality monitoring for catchment homes in Hawaii. You’ll learn why real-time testing matters, what UH CTAHR (the College of Tropical Agriculture and Human Resources) recommends, when to send samples to a certified lab, and the hidden dangers of stagnant warm water sitting in your tank.
Whether you’re a first-time buyer looking at a catchment property, a current homeowner who hasn’t tested your water in years, or an overseas investor doing due diligence on a Hawaii purchase — this is essential information that could protect your family’s health and your investment.
