Catchmenet workshop

Welcome to the Hawaiʻi Rainwater Catchment Program

Hawaii Rain logo

Rainwater catchment is an age-old method of catching rain from a surface (generally, a rooftop) and transporting it through a conveyance system (usually gutters and downspouts) to a storage container. This water can be used for domestic supplies, agriculture, landscape, water features (like fountains), public supply, or storm runoff control. In Hawaii, most rainwater catchments are used for domestic water supply and agriculture. The process of harvesting the rain is experiencing a resurgence in the U.S. and throughout the world as global warming and population growth threaten our limited fresh-water supplies.
