WHAT IS A HIPPO WATER ROLLER?

The Hippo roller carries 90 litres (24 gallons) of water inside a rolling wheel. With the Hippo roller the weight of the water is borne on the ground.

The water is transported by holding on to the handle with which the drum is pushed or pulled. This requires far less effort from people than carrying the traditional 20-liter (5-gallon) buckets or containers on their heads. Dimensions:

  • Drum: 50 x 50 x 65 cm. Capacity: 90 Litres. Weight: 8.5kg.
    A Hippo roller filled with 90 L water effectively weighs only 10 kilograms (22 pounds) on level ground.
  • Handle: 100 x 70 x 3cm. The steel handle provides firm control over difficult terrain while pushing or pulling the roller.
  • Lid: 135 mm / 5.3 inch diameter. The large opening allows for easy filling and cleaning of the interior. The sealed lid ensures hygienic storage of water.

 

QUALITY AND DURABILITY

Hippo roller used in tough rural conditions

The Hippo roller has a maintenance-free design for use in tough rural conditions where users have no access to spare parts. 

  • The drum is manufactured from UV stabilized Polyethylene
  • The flexible drum material has no seams or joints and forms a thick wall of protection
  • Stress distribution is around the entire drum
  • An embedded sand grit adds an extra layer of protection
  • The screw-cap wears IN and not out
  • An average lifespan of 5 - 7 years and more
  • Extensive field tests over many years have proven its effectiveness
  • Used in test cases as an anti-personnel demining device, absorbing the blast of landmines when filled with water
