Get the Full StoryGravity Water, with support from companies like Apple, is installing rainwater harvesting tech at hundreds of locations around the world.

At a remote elementary school in the Mekong Delta in Vietnam, until recently, access to safe drinking water was a daily challenge. The school tried to use groundwater, but there wasn t enough supply; the water was also contaminated with salt and metal. In the dry season, from December to April, droughts made the challenge worse. But last month, the school installed a new system that harvests rainwater, filters it, and then automatically supplies it to drinking fountains, the kitchen, and bathrooms.
