Warka consists of local and biodegradable materials such as bamboo, hemp and bio-plastic. Bamboo is the main material used for the frame structure. It is available locally in Ethiopia and can be found in many areas of the world. The mesh hanging inside the structure is under development at the moment. We are testing several materials with special coating that enables water collection. Atmospheric water vapor from the air condenses on the cold surface of the net, forms droplets of liquid water (dew), and falls under the influence of gravity into a container found at the bottom of the structure. The mesh technology is low-cost and relies on gravity and local weather conditions. The mesh will be custom made and produced, but the specific location for manufacturing it is to be determined.
