__NOTOC__<small-title />
The hippo water roller is a barrel-shaped container. It improves access to water by rolling along the ground. It was specifically designed to alleviate the suffering caused by traditional methods of transporting water in buckets.
====Uses====
The Hippo roller's main use is to enable people without water on tap to transport water from distant water sources back to their homes.
====Global and local impact====
The aim of the Hippo Water Roller Project is to reduce the number of people without adequate access to water by 1% = 10 million people. So far rollers have been distributed to 21 African countries as well as India, Mexico and South America.
====Community rollout====
* Sponsorship funding is secured and a recipient community is identified with or without the sponsor.
