Artificial Groundwater Recharge
Artificial recharge is needed due to the
overuse of water due to rapid industrialization, population increase, intensive
agriculture, urbanization. Artificial groundwater recharge is needed in the area of
overexploitation of groundwater, desaturation of the aquifer, poor quality of groundwater, saline
water intrusion (coastal belt), and drying of wells and pumps during the lean
period. Groundwater can be artificially recharged directly by redirecting water
across the land surface through contour bunding, percolation tank, check dam,
dug out pond; and indirectly through recharge shafts, injection wells, and
subsurface dykes.
