The Hippo Water Roller Invention by Pettie Petzer and Johan Jonker is used by women, children and the elderly to collect more water than using a single bucket. The two won the 1997 South African Design for Development Award for their work.
The Hippo Water Roller, a barrel-shaped container designed to roll 90 litres of water at one time along the ground, was purposely designed to alleviate the suffering caused by a lack of access to water. Its innovative design allows water to be placed inside the ‘wheel’, resulting in an effective weight of just 10 kilograms on level ground. Approximately five times the normal amount of water can be collected in much less time and with far less effort, transforming water collection from a daily chore to a task performed only a few times per week.
Today, the Hippo Water Roller has been distributed to communities in Africa and elsewhere.
