Details —For those with running water in their homes, water is light,
rolls right through the fingers, easily pours out of the faucet, and
gives us hygiene and hydration in minutes so that we go on about our
day. For families without such access, water is a different story. Water
is heavy. Water collection dominates the time women and their
school-age daughters have to spare on any day. They have the role of
water-bearers and they walk long distances, hours, back and forth, to
rivers and streams, with pails and jugs on their heads. The water they
get will be doled out carefully for drinking, cooking and washing that
day.
From economists to health experts to educators, there is
no argument that the daily burden of getting water is a drain on human
productivity, limiting the time women and school-age children could have
for other opportunities to work and attend classes. One attempt to
resolve this very basic issue has been the WaterWheel, a device from a
U.S.-based group called Wello, which describes itself as a social
venture. Wello has reinvented the wheel, in that they have used the
wheel to rethink water collection in parts of the world such as India
and Africa.
Fundamentally, the wheel answers the question, what
would be the benefit if you rolled water back to your village home
instead of carrying the water on your head? Wello in 2011 worked in
close collaboration with village residents in Rajasthan, India, on the
concept and Wello later on won a $100,000 Grand Challenges Canada prize
to develop the WaterWheel, which was announced by Grand Challenges
Canada, funded by the government of Canada, in November. According to
the prize project description: "The WaterWheel can be used to ferry
clean water from a community tap to the home, used to collect rainwater
during the wet season, to collect water from an open source during the
dry season, or used to travel longer distances to reach a safe water
sources when other options are unavailable."
The designers
considered different sizes before deciding on a 50 liters. The result is
a plastic wheel that serves as a 50-liter container that enables people
to roll ample collections from water sources at once rather than
carrying multiple jugs on their heads—between three and five times the
amount of water collected by traditional methods—in short, far more
water and in less time. The WaterWheel's form was inspired by the shape
of the traditional matka (pot). According to the Wello blog, they
manufactured their first production run of WaterWheels in Ahmedabad,
Gujurat in 2012. The device can also find use in irrigation and tending
herds of animals.
Wello also had to devise a sustainable
business model. According to the project description for the Canada
prize, the Wello team said, "We designed our business model around
extreme affordability. While similar products retail in the $75 to $100+
range, the WaterWheel will retail for $25-$30, making it accessible to
the people who need it the most." Wello said they had partnerships "with
organizations throughout the clean water value chain, local governments
businesses and NGOs, that will enable Wello to build on the progress
made and leverage local knowledge.'
A report in The Guardian
said that Wello plans to sell the WaterWheel in the Madhya Pradesh,
Rajasthan and Gujarat states, as well as explore opportunities for water
purification.
