Currently, all hippo rollers are manufactured in and shipped from south africa. However, exporting completed rollers is expensive, often doubling the cost. A mobile manufacturing unit has been introduced, whereby rollers can be built locally and at a lower landed cost.
 
 
====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.
 
* The Hippo roller is also used for drip irrigation for example in Zambia where small scale cotton farmers use the Hippo roller to water their crops.
* A wireframe that has been designed to attach on to the roller, transforms the device into a movable casualty bed for the sick or wounded.
* The same wireframe turns it into a transportable ‘spaza’ shop that includes a shade cover as well as a trolley that can be used to transport products to market.
* The Hippo roller has been used in test cases as an anti-personnel demining device, whereby it is rolled along the ground to absorb the blast of landmines when filled with water.
