Upper: traditional method of carrying water; lower: more water can be transported easily using the roller
The Hippo water roller, or Hippo roller, is a device used to carry drinking water more easily and efficiently than traditional methods, particularly in the developing world and rural areas. It consists of a barrel-shaped container that holds the water and can roll along the ground, and a handle attached to the axis of the barrel. Currently deployed in rural Africa, its simple and purpose-built nature makes it an example of appropriate technology. The device cost around $125 each and they are mainly distributed by NGOs.[1]
