Our Fresh Well Water

Northeast trade winds arrive in the islands ushering in an abundance of moisture developed through evaporated water from the Pacific Ocean.

The moist trade winds blow up against the Ko'olau and the Wai'anae Mountain Ranges, deflecting the moist air upwards to form clouds.

The moisture in the clouds condenses and falls to the ground as rain.

The rain that falls from these clouds is the predominant form of precipitation in Hawai’i and produces about two billion gallons of rain fall on O’ahu every single day.

The rain soaks into the soil and is stored by dike rock compartments, which overflow and fill our water sources.
