Sources of Water:

There are two main sources of water: surface water and groundwater. 

Surface Water is found in lakes, ponds, rivers, waterfalls, streams, reservoirs and sea.

Groundwater lies under the surface of the land, where it travels through and fills openings in the rocks. The rocks that store and transmit groundwater are called aquifers. The level of water below ground is called the water table. Groundwater can be extracted from wells or tube wells or hand pump.
