The particular Hippo water roller, or Hippo roller, is a new device for carrying drinking water more easily and successfully than traditional methods, especially in the developing planet. It consists of a barrel-shaped container which holds water and can roll alongside the ground, and a handle attached to typically the axis of the barrel. Currently deployed in countryside Africa, its simple and purpose-built nature makes that an example of suitable technology. The drum of the Hippo water roller is made from AND ALSO stabilized linear low-density polyethylene and is designed in order to cope with the rough surfaces found in rural areas. The drum’s volume is 90 liters (about 24 gallons) [1]. It has a huge opening (135 mm / a few. 3 inch diameter) for easy filling and cleansing[citation needed]. The sizing of the opening was actually determined by the particular availability of a sizable enough lid. The lid after that on its part determined the roll radius associated with the roller, since adequate clearance was required with the lid fitted to maintain the latter clear through the ground and any obstacles which might destruction ...
... it. The lid had been eventually further recessed about later models to boost its protection.
The steel handle allows the roller to be pushed or pulled over difficult and very rough terrain. The overall width of the roller with handle attached was determined by measuring the average width of a standard doorway and sized to allow it to be pulled through freely[citation needed]. This parameter together with the roll radius and the rounded shoulders eventually determined the average volume of 90 liters. The steel handle is fitted with special polymer end-caps to reduce friction and wear and prolong the life of the pivot cavities in the drum.
Throughout development a water roller manufacturer was drawn behind a vehicle over a dirt road at 20 km/h for 15 km with no considerable signs of wear on both the roller outer surface or pivot cavities. The painting tool is rounded at the shoulders to simplify tilting when wanting to put from the full roller. However, the roller is also very stable in the upright position when it rests on a small, flat work surface. The painting tool has hand grips at the bottom and top to make emptying the container easier. The clip or barrel, originally called “Aqua Roller”, was the brainchild of two engineers, Pettie Petzer and Johan Jonker Petzer and Jonker were acknowledged for work on the Hippo Roller in 1997 with the “Design for Development Award” by the South African Bureau of Standards as well as its Design Institute.
It is claimed that approximately five times the quantity of water can be transferred in less time with far less effort than the traditional method of carrying 20 liters (approximately 5 gallons) on the head.

Claimed benefits include:
* time savings (fetching water can be very time consuming in some poor rural environments);
* reduced effort;
* reduced strain (carrying heavy weights on the head every day for years puts strain on the body, particularly the vertebral column);
* increased water availability, with benefits for health and perhaps even enabling vegetables to be grown;
* hygienic storage due to the sealed lid on the roller.
Even though Hippo roller was mainly designed as a normal water walking gathering aid for underprivileged communities, several other utilizes have since been discovered. Because of the Hippo water rollers tightness it could act as a watertight container to keep belongings and clothes dry when going downstream in white-colored water rapids on extreme excursions.

It can furthermore suffice as a pot to be dropped along with life saving contents through helicopters or low soaring fixed-wing aircraft in inundated disaster areas. This could include food and medical materials, warm dry clothing plus blankets, and naturally, water. The polyethylene is lighter in weight than water and may stay only partly submerged, despite having fresh water within it. In fact, some rollers have been dispersed pre-filled with grain or even other foodstuff to communities. One of many draw-backs of the particular distribution in the rollers will be that the rollers can not be stacked efficiently to conserve space; thus transport ability is wasted.
Infotech, an information technology organization, initially sponsored the job as a social responsibility job known as the Hippo water zorbing Trust Fund. Currently, typically the project is supported monetarily by donor funding which often originates from individuals, corporate companies and non-profit organization partners. is really a non-governmental organization inside the United States designed to raise funds there. twenty-seven, 000 Hippo rollers have been distributed so far. As part of the investigation into the alleviation associated with poverty and scarcity regarding water in the significantly northern regions of Namibia, the Social Sciences Division associated with the Multi-Disciplinary Research Center at the University associated with Namibia, sponsored by UNICEF’s Directorate of Rural Development purchased 1000 rollers in addition to distributed them into the community. Six months after the introduction they launched an evaluation within the achievement and performance of the particular rollers as well since the social impact from the roller on the life of the recipients.
