Few water sources in drought-prone areas
In a country where 60 million people lack potable water, most of the water sources are problematic: Groundwater wells can run dry, and are often spaced very far apart. Rivers and lakes can become polluted, and technologies like desalination are cost-prohibitive.
Solution: Bamboo condensation towers grab water out of the air
The towers harvest water from rain, fog and dew. This isn't a new idea — people have been doing this for as long as they've needed water, often with air wells. Often built as high-rising stone structures, air wells gather moisture from the air and funnel it into a basin for collection. The WarkaWater functions in much the same way, using mesh netting to capture moisture and direct it into hygienic holding tank accessed via a spout.
Based on tests performed in its Italian lab, the company claims the latest iteration can harvest 13 to 26.4 gallons of water daily. That's less than most people flush away each day, but still a significant quantity.
