Warka Water towers harvest drinkable water from the air
In this exclusive movie, Italian architect Arturo Vittori explains how his wooden Warka Water structures can provide clean drinking water for rural communities in the developing world. The tower consists of a bamboo frame supporting a mesh polyester material inside. Rain, fog and dew condenses against the mesh and trickles down a funnel into a reservoir at the base of the structure. A fabric canopy shades the lower sections of the tower to prevent the collected water from evaporating.
