Lack of surface water sources and falling water table has made availability of clean drinking water a major problem in Rajasthan.

For human beings, the need gets addressed to some extent but for animals this need is much less appreciated.

Swayambhoo Sharma came up with an interesting solution to address the drinking water needs of animals.

He developed an arrangement such that every time people pump water for their use, 20 per cent of pumped water will directly go to fill animal water trough. Since most people feel lazy in filling drinking water trough for stray animals, this innovations solves this problem by a kind of tax at source.

Another problem faced in hand pumps is that a single person finds it very difficult to pump and at the same drink water (without a vessel with him/her).

Chandan, then a first year student at IIMA came out with an idea of storing water in the body of the hand pump so that having pumped, one could use a tap and drink water like any other tap.

Yusuf Khan and Madan Lal Kumawat, two other innovators combined the idea of Chandan and Swayambhoo Sharma and developed a hybrid model.
