Water is one of the natural resources, which is widely used for various purposes such as drinking, washing, bathing, cleaning, cooking, irrigation, and other industrial and domestic uses.
Our earth is covered with 97% of water. But only 1% of water is available for use which is fresh water.
There are many sources of water. Three major sources are:
Groundwater: It is a source of water that is under the land surface. It is accessible by wells, tube wells, and hand pumps.
Surface-water: This type of source is found on the surface of the earth like ponds, rivers, etc.
