1. Introduction
Water is an important element for all human beings in the world. Our body consists mostly of the water. We need water for drinking, cooking, washing, agriculture and to run our industries. We usually take it for granted because of its availability; but when in scarcity it becomes our most precious resource. Every raindrop that fall from the cloud is very soft and the cleanest water sources in this world (Texas Water Development Board, 2005). The falling raindrop acquires slight acidity as it dissolves carbon dioxide and nitrogen (MHLG, 2008). Rainwater is a part of hydrologic cycle; the never-ending exchange of water from the atmosphere to the ocean and back again as rainwater. The precipitation like hail, rain, sleet, snow and all the consequently movement of water in nature forms are from part of this cycle. Rainwater quality always exceeds the surface water and comparable to ground water because of it does not come in contact with soil and rocks
