PlayPump.......drawing water and pumping it is child's play

The PROBLEM - No electricity in the village. Cannot afford a diesel generator. Then how to get groundwater in a tank overhead so that water can be made available though pipes and taps around the village.

The SOLUTION - A toy for children. Yes a merry go round wheel.  Children are endless bundles of energy as they play on for hours. But underneath this wheel draws ground water and pumps it in a tank overhead (seen in the background). The groundwater drawing works much like our common Indian hand pumps.

The picture below depict the working of this pump.

This technology is being implemented by "Water for People" in African Nations on charity basis and has been developed by PlayPumps International-US.

The Q Drum......how simple ideas solve BIG problems

Here is the PROBLEM. Supply of clean drinking water and how it is fulfilled in many rural areas in the Third World.

And architect Hans Hendrikse put his grey cells to use and came up with a solution that could reduce the long term side effects caused to the backs and necks of these folks. Now even kids can carry 50 - 70 litres of water for miles without any undue strain. He got recognition in form of "ROLEX Award for Enterprising Individuals" for implementing the solution in South Africa.
Below are some pics of the Q Drum and Hans himself in the second image here.
