The sources of water are:
surface and underground water
springs, rivers lakes
excavated dams and rock holes
all of these
Following are the sources of water:
Surface water: Water which falls on the ground as rain or hail.
Underground water: Water that is stored beneath the Earth and is pumped out using machines.
River, lakes or springs: These are the natural water storages.
Rock holes: Sometimes large rocky outcrops contain low areas in which water is trapped. These low areas make good water stores.
Excavated dams: Excavated dams are made by scooping out soil to make a large shallow hole.
