If you go to Ethiopia, you鈥檒l find a strange palm
-like structure, which is called WarkaWater.
It gathers water from fog and condensation
锛堟按鐝狅級
and is invented by an Italian firm.
When Italian designer Arturo Vittori and Swiss architect Andreas V
ogler first visited Ethiopia
in 2012, they were shocked to see women and children forced to walk miles to access what, for
them, had always been within easy reach, water.
Only 34 percent of Ethiopians have access to a reliable water supply. Some travel for up to
six hours a day to fetch some or, even worse, has to use pond water polluted by human waste,
subject to the spread of disease.
Worldwide, about 768 million people
鈥?/p>
two and a half times the U.S. population
鈥攄on鈥檛 have
access to safe drinking water. So just imagine if we could just pull water out of thin air? That鈥檚
what
Vittori
and
V
ogler
asked
once
they
saw
the
severe
problem
and
promised
to
take
action.
Their
firm,
Architecture
and
Vision,
has
since
come
up
with
WarkaWater,
a
grand
palm-like
structure that may look like something you鈥檇 see in a modern art museum, but it鈥檚 been designed
to harvest water from the air.
WarkaWater, which is named after an Ethiopian fig tree, is composed of a 30-foot bamboo
frame containing a fog-harvesting nylon net that can catch water easily, can be easily lowered for
repairs and allow communities to measure the water level. Collecting water through condensation
is hardly a new technique, but the creators of WarkaWater say their tree-inspired design is more
effective, maximizing surface and perfecting every angle to produce up to 26 gallons of drinkable
water a day
鈥?/p>
enough for a family of seven.
Western organizations have been working to provide clean water access in Africa for decades,
so WarkaWater joins a very long list of earlier attempts. So far, high-tech solutions, like the once
promising Playpump, have failed, mostly due to high costs and maintenance issues.
This is where WarkaWater stands apart
鈥?/p>
a lower-tech solution that is easy to repair and far
more affordable than digging wells in the rocky Ethiopian plateau.
