Hippo Water Roller

Especially in the developing world, many water-fetchers — often women and children — are forced to struggle lugging giant buckets over their heads or by hand. The Hippo Water Roller was invented by Pettie Petzer and Johan Jonker, and they won the 1997 South Africa Design for Development Award for their work. The Hippo Water Roller reduces physical effort and increases the amount of transportable water. The 90-liter drum can carry 90 kilograms (198.4 pounds) of water. It has a steel handle that controls the rolling when the drum is pushed or pulled across rough terrain.
