Potable Water from Air by UTEC



A water-producing billboard by Lima’s University of Engineering & Technology (UTEC) was recently erected along the Panamerican Highway, in the village of Bujama. In a region receiving only 1″-2″ of rainfall annually, this technology brings safe, potable drinking water from humidity in the air. This area has a humidity level averaging around 98 percent and this billboard has already produced over 2,400 gallons of water in a three month period time.



It’s not entirely self-sufficient, requiring electricity (it’s not clear how much) to power the five devices that comprise the billboard’s inverse osmosis filtration system, each device responsible for generating up to 20 liters. The water is then transported through small ducts to a central holding tank at the billboard’s base.

Imagine what you could accomplish in any number of troubled spots around the world which needs potable water with a solution like this.
