Solving the water crisis faced by many countries in Africa and the Middle East seems like a massive undertaking involving lots of plumbing, construction and planning.
But there's a simpler solution which addresses the needs of the individual families instead of the nation as a whole- the Hippo Water Roller.
The Hippo isn't a re-invention of the wheel, simply a way to use the rolling motion to help people transport drinking water home far easier and in much larger quantities.
Before the Hippo started changing lives people could only carry about 20 liters of water home at a time, in a bucket carried on their head no less, but the Hippo allows them to roll 90 liters home easily and quickly.
