The Hippo Water Roller
The Hippo water roller is a drum that can be rolled on the ground, making it easier for those without access to taps to haul larger amounts of water faster.
Two out of five people in Africa have no nearby water facilities and are forced to walk long distances to reach water sources. The Hippo roller can be filled with water and then pushed or pulled using a handle. The weight of the water is spread evenly so a full drum carries almost five times more than traditional containers, but weighs in at half the usual 20 kilograms, allowing it to be transported faster. A steel handle has been designed to allow two pushers for steeper hills.
