Hippo Roller, Device That Provides Access To Clean Water

The Hippo Water Roller Project began in 1994 with the aim of facilitating the transport of water in difficult areas. The invention especially helps vulnerable people living in rural areas of Africa.

For many people in Africa, the search for water has become an arduous task that can take up to six hours to collect heavy buckets that they must carry on their heads.

According to the United Nations, approximately 2.1 billion people do not have access to safe drinking water. Two South Africans became aware of the situation and designed a device to try to help reduce this situation.

 It is a drum that weighs 90 kilos, but when pushed or rolled on level ground, it only weighs 10 kilos. Therefore, it facilitates the transfer of women, children and vulnerable people.

With it, you can collect five times more water than a single bucket. The weight is supported by the ground and distributed over a rolling surface.

With the use of this technology, people have more time for family, crops and even for studies, which results in improved quality of life.
