Protect Our Water. Protect Hawaii's Future.
Trash Free Hawaii
Anything that goes into our storm drain system goes directly into the ocean untreated, negatively affecting water quality and marine life. Learn more about the Hawaii Department of Transportation (HDOT) Storm Water Management Program’s #TrashFreeHawaii campaign, focused on doing your part to prevent storm water pollution.
Baby Steps
Small actions can lead to big change. Whether it is identifying the destination of household downspouts, recycling, or changing the way cars are washed, we can all help prevent storm water pollution from entering Oahu’s water resources.
Big Steps
Preventing storm water pollution from entering your area’s water resources may require a greater effort. For example, utilizing a rain barrel to capture roof runoff will help ensure that storm water will not transport pollutants into the nearest storm drain inlet.

Giant Steps
We can go even further to prevent storm water pollution. Replacing your paved driveway with a pervious surface will help storm water filter into the soil rather than flow over paved surfaces.
Adopt-A-Highway
One of the most critical ways to keep our storm water runoff free of pollutants and debris is to adopt a highway. The HDOT Adopt-A-Highway program is a public service program that allows volunteers from any organization to pick up litter along Oahu’s state highways. This is your chance to make a personal contribution to a cleaner Hawaii!
