Rolling Water instead of Carrying it

It is an age-old image of rural India: a woman trudging a long distance with a huge pot of water precariously balanced on her head. And despite an ambitious nationwide effort to provide piped water to every rural household, it remains a common sight in most Indian villages.

An American “social entrepreneur” is now hoping to change that, by replacing the head-borne water pot, which carries 10 litres (2.2 gallons), with a 90-litre plastic drum that can be rolled home.

The concept is not new – the Q Drum and the Hippo Water Roller, for instance, were invented in South Africa in the early 90s. But their popularity has been limited because of their price, $70-$100 (£43-£61) each, too high for the developing world.

After trials in arid Rajasthan, Cynthia Koenig, who has an MBA from the University of Michigan, has set up Wello WaterWheel to make plastic water barrels for as little as $20-$30. The prototype has been created by a US design firm, Catapult.

“We’ll set up a pilot manufacturing unit and roll out the barrels by early next year,” said Koenig, 34. “During trials in Rajasthan villages, we found that people were really excited by it. The magic will be in making the right product at the right price and distributing it as widely as possible.” After tests in India, Mexico and Haiti, she is confident that the WaterWheel can be an all-terrain alternative to water pots.
