Water is life. Water is a basic need. Water makes up most of the world, in fact the planet is 75% water. Every living organism needs water to make food, therefore water is the most important gift that nature has given mankind.

For these very reasons, the prevalence of water born diseases caused by accessing to unsafe drinking water sources has increased at alarming rate. The low level of economic growth, coupled with soaring population growth, high level of illiteracy rate and low level of education/awareness have also contributed to the burden of ill health country wide (UNESCO, 2006).
Oromia is the largest and most populous regional state in the country. It has a land area of 359,620 square kilometers, straddling the middle of the country, and has a very varied topography (high mountains, valleys, rolling plains and lowlands, including part of the Rift Valley). Reflecting its geographical diversity, rainfall varies considerably from 400 mm a year in the south to 2,400 mm a year in the Western Highlands. Fifty percent of the
