Rain water harvesting

It is a very important method of conserving water especially in urban areas.

In this method, the rain water which falls on the roof of the building is collected in storage tanks, deep pits or reservoirs with percolation. This helps water conservation in several ways:

1.    This helps to stop the water run off to the rivers where it dry up soon after the rain stops
2.    Stored water can be used for gardening, for live stocks and for domestic use
3.    This rain water can be collected in reservoirs with percolation so that it will raise the declining under ground water table and can help to augment water supply.
