● Water is the most precious natural resource. Most of us take water for granted.

● We are now increasingly becoming aware of the importance of water to our survival and its limited supply.

● Now it comes very essentially to save water by harvesting it.

● Water harvesting means capturing rain water, where it falls and capture the runoff from, catchment and streams etc.

● Generally, water harvesting is direct rainwater collection.

● This collected water could be stored for later use and recharged into the ground water again.

● Rain is primary water source lakes, ground water and rivers are the secondary water source.

The two advantages of water harvesting:

(a) Overexploitation of water resources will be reduced.

(b) Helps to recharge the ground water to increase the water table and provides moisture for vegetation over a wide area.
