Mahalo to everyone who joined us at Windward Mall on September 20, 2025, for the Board of Water Supply's Imagine a Day Without Water Event!
More than 20 government and community groups shared hands-on fun—from rain barrel workshops to Xeriscape crafts—the day was a splash.
The event also highlighted the One Water concept, showing how all water is connected and must be managed together.
Next year we’ll be at a new Oʻahu location to keep sharing the value of water and the One Water concept—see you there!
Let's make every drop count!
