Here’s an extremely clever prototype for home made water purifiers.
The designer won the Australian Design Award recently, so it’s passed lots of important conceptual and practical tests. And at a first glance it appears this purifier might be a real success story.
Prize winner, Julie Frost, from the University of New South Wales in Sydney, Australia, developed a cleverly shaped plastic bucket with a dark polyethylene lining, that ladies in developing countries can fill at a well and then balance on the heads to hold home as they’ve traditionally done.

So far, nothing has changed. But once the precious water arrives home in Julie’s bucket, that she calls a mvura (Shona for ‘water’), the changes come thick and fast.
First, the woman places the bucket on the ground and it opens in to a flat lotus flower shape. Amazing! The flexible black polythene lining spreads out, still holding each of its 15 liters of water, so nothing is spilled. That is then put in the hot African sun … and Julie’s magic begins in this ingenious home made water purifier.
In only two hours the heat of sunlight, amplified by the black plastic, heats the water to 65 degrees. The village water carrier knows when this temperature has been reached because some simple soybean wax will have melted. And when that has happened the water becomes pasteurized and harmful bacteria is going to be neutralized.
Julie has succeeded in adapting a bucket. But unfortunately she still has some way to go to develop a secure, reliable and effective home made water purifiers.
