2025 Imagine A Day Without Water


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!

Leaking Pipe Leaks in household and underground water pipes on your property can be costly and wasteful. Check for possible leaks at least once a month, whenever you suspect a leak exists, or before you travel for an extended period of time.
