In India since the water table is going down day by day we are giving much stress on the rainwater harvesting.
By doing so instead of water getting mixed with the sea water after the rains we make the water to get into the earth to elevate the water table. we have many ways of doing it.
The whole idea is preventing the water from wasting and utilizing the same for proper utilization for the future!
Government is not giving any permission to get some new tube wells and for the areas where we need tube wells we are suppose to have some water harvest projects before digging a new bore well!
