“Warka Water” is a solution designed by two Italian engineers and is based on a very simple principle. It traps water vapor from the air through condensation. Standing 9 meters (30 ft) tall, the framework is made out of bamboo and a special polyethylene fabric that collects water droplets. It weighs around 60 kilograms (130 lb) and can be put together by four people in a couple of hours without scaffolding. Each pillar can produce around 100 liters (26 gallons) of clean, fresh water a day.
