UNDERGROUND RAINWATER ...

 UNDERGROUND RAINWATER HARVESTING can solve water crisis of India ( most parts) without Interlinking of Rivers:

India is blessed with  annual 3500 BCM rainwater ( billion cubic meter), which is  4 times more than its annual water need of approx 700 BCM. Still we are extracting approx 40 % of this water from Groundwater and this does not get replenished by natural recharging of Rainwater in the land where rainwater falls.

We face water crisis  in most part of India, as Dams and rivers cant meet the water demand after Rains. At the same time , during heavy rains period, this very water stored in dams causes floods in lower lying area when doors of Dams are opened to save these dams from bursting. 

So we have either Drought or Floods.  

Biggest consumer of this water is agriculture , demanding more than 80% of this 700 BCM, Industry comes second with 12% and Domestic household need is only 7-8%. 

If only we can save this excess rainwater during monsoon in the Ground TO INCREASE SOIL-MOISTURE , to be available to plant roots even after rains ( Nov to June), we can reduce the load of Agriculture water Demand on DAMS (our existing Above Surface Storage of Water) AND Grondwater. This will solve the water crisis of India permanently .

This can be achieved by  UNDERGROUND RAINWATER HARVESTING in individual farms and open lands.
