Global Reach

The Hippo Roller is an appropriate technology widely accepted in many countries by undeveloped communities where there is no reliable water infrastructure. Approximately 44,000 Hippo Water Rollers have been distributed mostly in South Africa and at least 20 other African countries, directly benefiting in excess of 300,000 people (based on a typical household average of 7). To date, more than 7 Billion liters of water have already been ‘rolled’ over a combined distance of 500 Million km (conservative estimates). Much more needs to be done!

Widely accepted

Hippo Rollers are proven in the field and well accepted by communities and beneficiaries to collect and carry water far more easily than traditional methods.

South Sudan

We travelled to Rumbek in 2010 to evaluate what impact the Hippo Water Rollers had made on the community of Maleng-Agok after 8 months of use.

Government approval

The SA Government found in 2012 that the Hippo Water Roller is indeed an appropriate innovative technology for most rural areas in South Africa.

Case Study: Rumbek, South Sudan, December 2010hipporoller-brick-making

  • There is no question that the Hippo Water Roller Project has made a significant impact and contribution to the people of South Sudan.
  • When you see how rural and spread out the homes are, it’s easy to understand why it would be so difficult and costly to install piped water all over South Sudan.
  • Most water points in South Sudan are manual boreholes which have to be pumped up and down to extract water from below.
  • Boosting Local Businesses – Clay brick manufacturers said that their production rate had almost doubled because they were able to spend less time and effort collecting water which was good for business.


Department of Rural Development, South Africa, 2012

  • The Chief Directorate: Technology Research and Development (TRD) of South Africa’s Department of Rural Development and Land Reform (DRDLR) identified Hippo water rollers as an appropriate technology and conducted an impact assessment study of the Hippo roller in some Eastern Cape areas faced with water supply challenges.
  • In October 2012, the DRDLR produced the Hippo Water Roller Impact Assessment Report – 8 Selected Sites, which is a summary of the observations done by the DRDLR reasearch team and the issues that were raised by the members of 8 communities in the Eastern Cape. An insight into people’s concerns, motivations and aspirations was gained using qualitative research.
