The hippo water roller is a barrel-shaped container. It improves access to water by rolling 90 litres (24 gal) along the ground. It was specifically designed to alleviate the suffering caused by traditional methods of transporting water in buckets. It carries more  Its innovative design provides for a large drum capacity of 90 litres / 24 gallons. Far less effort is required to roll the heavy weight of water more efficiently(90kg / 200lbs) along the ground than carrying the traditional 20-liter (5-gallon) buckets on the head. The effective weight on level ground is just 10kg (22 pounds).
Currently, all hippo rollers are manufactured in and shipped from south africa. However, exporting completed rollers is expensive, often doubling the cost. A mobile manufacturing unit has been introduced, whereby rollers can be built locally and at a lower landed cost.
