The Hippo Water Roller is a barrel-shaped container, with a large screw-cap and clip-on steel handle, designed to transport 90 liters of water with ease. Its innovative design allows water to be placed inside the "wheel", resulting in an effective weight of just 10kg on level ground. Specifically designed to alleviate the suffering caused by a lack of access to water in rural communities, the benefits are immediate. Much more water (5 x) can be collected in less time with less effort enabling women and children to improve their chances of a proper education and economic empowerment. Even men now help with this task. One roller serves a typical household of 7 for approximately 5 years or more.
