Warka towers pull drinking water out of condens
Water, and more specific clean drinking water is an increasing problem in large parts of the world. Industrial designer Arturo Vittori says his WarkaWater tower can provide remote villages with more than 25 gallons of clean drinking water per day. A luxury!
At this moment 1,1 billion people has no access to any type of improved drinking source of water. Because of that, 160 million people are infected with schistosomiasis causing tens of thousands of death yearly. Mostly young children.
This Warka is a revolutionary new way to provide clean water as well as ensure long-term environmental. Once locals have the necessary know how, they will be able to teach other villages and communities to build the WarkaWater towers.
25 gallons every day
At first glance, the 30-foot-tall, vase-shaped towers, named after a fig tree native to Ethiopia. The large 30 foot, 88 pound structures are made out of juncus stalks or bamboo woven together to form the tower’s vase-like frame. Inside, a plastic mesh material made of nylon and polypropylene fibers act as micro tunnels for daily condensation. As droplets form, they flow along the mesh pattern into the basin at the base of the towers. By harvesting atmospheric water vapor in this way, it’s estimated that at least 25 gallons of potable water can be sustainably and hygienically collected by the towers every day.
Warka founder Vittori: “Because the most important factor in collecting condensation is the difference in temperature between nightfall and daybreak, the towers are proving successful even in the desert, where temperatures, in that time, can differ as much as 50 degrees Fahrenheit. It’s not just illnesses that we’re trying to address. Many African children spend several hours every day to fetch water. Time they could invest for more productive activities and education. If we can give people something that lets them be more independent, they can free themselves from this cycle.“
Each tower costs approximately $550 and can be built in under a week with a four person team and locally available materials.
