The Warka Tower is capable of collecting 10-20 gallons of water per day to supply to local populations using a concept that won it the World Design Impact Prize.
The tower was designed by Arturo Vittori and his Italian design studio, Architecture and Vision. The entire concept functions as a water-catchment system that produces clean potable water by harvesting rain, fog, and dew from the air. The project was designed to be low cost and scalable, which lead to its construction with 4 main materials: bamboo, polyester mesh, polyester cable, and hemp rope.

Nearly 768 million people don’t have access to safe water around the world and every day 1,400 children under 5 die from water-based diseases. The problem is real and the Warka Tower might be the right solution.
The stunning tower stands 30 feet tall and can collect up to 20 gallons of water per day. Each structure is comprised of two sections: a flexible but rigid exoskeleton made from bamboo and a stretched internal plastic mesh. The polyester fibers work as a tiny scaffold for condensation to form, after which they drip down into a basin located at the bottom of the structure. Due to the nature of how the tower works, it functions best in humid tropical environments. The entire structure can be built in 4 weeks and erected in one hour by a team of 16 people.
Finding clean water in these remote areas isn’t as simple as you may think. In many cases, drilling wells isn’t an option due to groundwater pollution. Collecting water from rivers or lakes is an equally bad solution for the same reason.
The design is just now gaining significant traction as the company plans to mass produce the tower in early 2018.
