Recharge Of Aquifers
In western indias unconfined alluvial aquifers, it is being
increasingly realized that groundwater depletion can be
countered only by importing surface water.
Sardar Sarovar Project (SSP)
The purpose of the project is to identify reliable sources of
water of sufficient quantity and quality to supply.
