Customer Service Water Quality Conservation Water Resources Community About Us
Welcome to the Honolulu Board of Water Supply

Rain born of the heavens, slowly purified by nature over time, becomes a precious resource on our island home.  We must always conserve and protect the water supply entrusted to us, protecting it for future generations.  Use what we need, but let's not waste it.

Together we will make a difference.

In and Around the Community
There is no life without water. Hawaii's volcanic landmass and high rain-catching mountain ridges give our islands the tools to create an efficient and dependable water source to sustain life. This cycle of renewal is one of constant motion and transformation. Explore how Oahu makes our water through an interactive demonstration of the water cycle.
