The Acqua Viva rainwater collection system is made up of a series of spiraling Flowforms that collect rainwater and send it into storage vessels. The terracotta flowforms and vessels are designed to be hung on a series of cables, where they capture rooftop runoff and allow water to cascade down through each form. Flowforms encourage the water to act in a natural way, spiraling and falling into beautiful egg-shaped vessels. The water is stored for use to water nearby plants and can be accessed via a spout at the bottom. When there is too much water for the vessel, water spills out over the top and flows down through more flowforms and into the next vessel.
