Conservation – Water is Life


Save Water Now

The island of Oʻahu sustains a population approaching one million people. Our primary source of drinking water is groundwater: fresh water, filtered through mountain watersheds and held within the porous volcanic rock of the island. Our island water supply is a precious resource that requires our care and concern. Like the favored plant from the garden, water needs special attention and protection. Because of our growing population, effective water management is a major element in planning for expanding water needs.

To extend the life of this precious resource, we need to be more conscious of water conservation practices in our everyday lives. With a little effort and a little common sense, you can make water conservation a way of life by locating and fixing leaks, choosing plants and trees that require a minimum of water, and following other water-saving tips that can save thousands of gallons every year.
