Hawaiian islands

Being surrounded by water doesn't mean we have a lot of it.

Please treat every drop of fresh water like it's a gift.
— OUR MISSION —

Our fresh water is disappearing.

In recent decades, Hawai‘i’s annual rainfall has been declining, while its population has grown and tourism has exploded. This imbalance between supply and demand has mightily strained the islands’ freshwater supply.

This campaign was formed to create awareness of this critical issue and help save our islands’ supply of fresh water. Because without that water – our lifeblood – Hawai‘i wouldn't be the magnificent place that it is.

Which is why our goal is to get both visitors and residents alike to start treating every drop of fresh water like it‘s a gift for today and future generations.

And when we all do our part, we’ll have a lasting effect on saving Hawai‘i.

Water is an extraordinary process.

Here in Hawai‘i, when we turn on the tap, we become part of the extraordinary process of our fresh water system that involves the clouds above us and the volcanic rock below us.

Rain water slowly filters through our mountain landscapes and is held within the volcanic rock of our island and in our streams. This process can take as long as 25 years for fresh water to travel from the clouds to our faucets!

During your stay, help us ensure our fresh water supply for today and the future.

— WAYS TO HELP —

Use only what fresh water you need.

Turn off the faucet while brushing your teeth or washing hands.

While in the shower, turn off the water until it’s time to rinse off.

Put unfinished glasses of water in the mini-fridge for later.

Help us use water wisely.

Put out the linen change card if you'll re-use the sheets.

Hang towels on the rack if you're going to re-use them.

If you see a leaking faucet, let the property staff know.

Help us protect our watersheds.
