Safe drinking-water and adequate sanitation services to all is perhaps the greatest development failure of the 21stcentury. The most egregious consequence of this failure is the high rate of mortality among young children from preventable water-related diseases. Water is essential to sustain life, and a satisfactory (adequate, safe and accessible) supply must be available to all.
Improving access to safe drinking-water can result in tangible benefit to health. Nearly, one billion people suffer needlessly without access to safe drinking water and over five thousand children die each day because of water related diseases. Water-related diseases: caused by insect vectors, especially mosquitoes, that breeds in water; include dengue, filariasis, malaria, onchocerciasis, trypanosomiasis and yellow fever. Drinkable water sources are distant from most villages in India. Women and children especially spends hours of labor just to meet the basic needs of their families walking five miles and more to nearby towns just to have access to drinkable (purified) water. Some well to do inhabitants in these villages travel long distances with motor bikes and trucks which consume fuel and pollute the air. Moreover, a family of five needs a minimum of fifteen gallons of water each day. The only way to sanitize the stream water available to these villages is by boiling which also consumes precious resources and contributes to deforestation since the only source of energy for boiling this much water is firewood and charcoal(Payment and Hunter, 2001; Howard, 2006). However, a number of studies from low-income countries have indicated that improved access to water –and the resulting increases in the quantity of water or time used for hygiene –are the determining factors of health benefits, rather than improvements in water quality (Curtis and Cairn cross, 2003). The objective of this work is to design a mechanism to be used with water filter to supply purified water for villages and remote places by harnessing the human pedal power.
