A different kind of “water wheel”

The Artdog Image(s) of Interest

This month the Images of Interest have been exploring better ways for people around the world to gain better access to clean, safe water–defined by the UN as a basic human right, but out of reach for millions, if not billions (different sources cite different numbers) of people all over the world.

Previous posts have discussed ways to make the water safe to drink, via LifeStraws and ceramic water purifiers but before you can clean it you have to get it. 

And bring it home.

Some people in “undeveloped” parts of the world may spend up to a quarter of their lives hauling water.

Enter the Hippo Water RollerThis reimagined child of a water barrel and a wheelbarrow holds about five times as much as the average bucket, and was designed by two South Africans who grew up in rural areas, Pettie Petzer and Johan Jonker.

They’ve been making them since 1991. As of mid-2016, some 50,000 of them had been distributed to more than 20 countries, and countless lives have been improved.

I guess that’s just the way they roll.*

*Augh! Sorry! Couldn’t resist.

VIDEO: Many thanks to Hippo Roller’s Flickr Photostream for the still shot of Hippo Water Roller users in action, and to Insider on YouTube for the Hippo Water Roller video. And a tip of the hat to Warren Whitlock (@WarrenWhitlock) for alerting me to this ingenious solution to an age-old problem!

These aren’t just any old flowerpots

These Cambodians are making life-saving devices. Those things that look like flowerpots are actually ceramic water purifiers. They save lives by making it possible for people to have clean, safe drinking water, even when their only water source is a muddy, polluted river. They’ve dramatically cut down on diarrheal illnesses since they were first introduced in 2002. That they can be made locally and employ local people is an added bonus.

The filters work surprisingly well, for such a low-tech solution. They eliminate approximately 99.88% of water-borne disease agents.

As far as I could discover, the principle was first developed by Henry Doulton, a Victorian pottery manufacturer (his father co-founded the Royal Doulton company), who was inspired by the discoveries of Louis Pasteur.

In honor of Social Justice February, this month I’m exploring innovative, sustainable technologies for delivering clean water to populations in needThe United Nations declared in 2010 that access to clean water and sanitation is a basic human right, and called upon all nations to help ensure that “safe, clean, accessible and affordable drinking water and sanitation” should be accessible to everyone on the earth. Yet such access is unavailable to literally billions of people, and the pressures of climate change and population growth make the problem worse each year.
