20081227-the-goals3In a recent interview with Hippo Water founder Cynthia Koenig, we learned a bit more about the recent re-design of the Hippo Roller. It was a dream experience for this blog.


The challenge

Traditional water transport

  • In third-world countries, women and children must haul water over long distances in order to supply their communities with clean, safe water.
  • Alternative sources like wells are only functional 6-8 months of the year, and well pumps are unreliable or fuel to power them can be difficult to obtain
  • The first version of the Hippo Roller multiplied the hauling capacity of a single person but the cost of manufacturing and shipping them limits the number of people they can impact.
  • Hippos are currently manufactured in South Africa but are needed in other countries such as India and Siberia.

Enter Project H Design and Engineers Without Borders
Emily Pilloton took interest in the Hippo challenge and began with fundraising for a “Hippo drop” – the term for a distribution of Hippos to a community – as the founding project for Project H. During the Hippo drop the designers visited the Johannesburg manufacturing facility and identified an opportunity for design improvements.

Project H partnered with Engineers Without Borders’s Appropriate Technologies’ Design Team and split into two teams: one focused on reducing cost in any way, and one focused on playing with the inherent design of the device. We find the Flickr photos of the design process to be fascinating. Here are a few of our favorites:

20081227-the-goals3The Hippo Roller team has just shared great news about their redesign project. With the Hippo Water Roller, an individual can transport 24 gallons (200 pounds) of water as if pushing a 22-pound weight. This is enough to provide water for a family of five people for a day, with a single trip. However, the biggest obstacle to distributing these life-changing devices broadly was its $100 price tag, including shipping the cumbersome Hippos.

Hippo Roller brought the challenge to Project H Design and Engineers Without Borders, resulting in a two-part, nesting, stackable version of the Hippo which cuts the required shipping volume to 1/3 the original space. Ikea would be proud!

The next challenge is to cast the mold that will enable the manufacture of the Hippo 2.0s. To raise the $5000 needed to create this mold, Hippo has launched a $25×200 campaign. For a $25 donation, 200 supporters can sponsor the original mold and bring more Hippos to more people in need of safe water globally.
