As water shortage is a serious issue in many parts of the world, a means of efficiently harnessing safe drinking water from thin air without the need of expensive infrastructure could be a real lifesaver. Italy’s Architecture and Vision is developing an off-grid bamboo tower called Warka Water that promises just that: the firm says it could collect an annual average of up to 100 liters (26.4 US gallons) of water per day.<\/em><\/p>\n

Once completed, Warka Water will rise to a height of 10 m (33 ft), weigh 60 kg (132 lb), and be secured to the ground with eight guide ropes. The tower consists of a lightweight woven bamboo structure, while an inner plastic mesh retains water droplets from passing fog, which fall into a collector and a large tank. Any rainwater and overnight dew also collects in the tank.<\/p>\n

Warka Water will sport a canopy that offers shade to people drawing the collected water, and a series of rotating mirrors which Architecture and Vision says will be sufficient to keep birds away. No electricity is required for any part of the passive water-harnessing process, and the firm says the bamboo structure will take six people four days to construct. On-site assembly should take four people just three hours, without the need for cranes or any other building machinery.<\/p>\n

\"warka_water\"<\/a> \"warka_water-3\"<\/a>It’s going to be a long road until that point, though. The essential idea behind Warka Water appears sound, but its success will hinge on overcoming a long list of other concerns, including the quantity and quality of water drawn, the structure’s durability, and cost. Though rated as lasting up to 10 years, it will require locals to be trained and made responsible for maintenance, and while the estimated cost of under US$1,000 may seem relatively cheap compared to standard water supply infrastructure, it’s still a lot of dough for an impoverished area.<\/p>\n

It also remains to be seen if it could harness as much water as the company estimates \u2013 and on this note we’d encourage all-due skepticism. Indeed, though Architecture and Vision has produced a small working prototype, the first full-scale field test won’t take place until the necessary funds have been raised by a recently-launched Kickstarter campaign, and it won’t be suitable for all areas.<\/p>\n

“It is first and foremost an architecture project. WW should not be considered as the solution to all water problems in developing countries but rather as a tool that can provide clean water in selected areas,” says the firm. “Particularly in mountainous regions where conventional pipelines will never reach and where water is not available from wells.”<\/p>\n

If you’d like to try and help the team overcome these hurdles, as of writing its Kickstarter campaign still has 18 days to go. Raised funds will go toward developing a working unit, and promised rewards include Warka Water-related apparel, and a scale model. If all goes well, Architecture and Vision will eventually seek further donations for Warka Water units to be installed in select locations in Ethiopia, before potentially rolling out the system worldwide.<\/p>\n
