GUIDE ON ARTIFICIAL RECHARGE TO GROUND WATER
1.0 INTRODUCTION
The artificial recharge to ground water aims at augmentation of ground water reservoir by modifying the natural movement of surface water utilizing suitable civil construction techniques. Artificial recharge techniques normally address to following issues (i) To enhance the sustainable yield in areas where over-development has depleted the aquifer. Conservation and storage of excess surface water for future requirements, since these requirements often changes within a season or a period. To improve the quality of existing ground water through dilution. To remove bacteriological and other impurities from sewage and waste water so that water is suitable for re-use.
(ii)
(iii) (iv)
The basic purpose of artificial recharge of ground water is to restore supplies from aquifers depleted due to excessive ground water development.

Concept of Augmenting Ground Water Reservoir Ground Water or Sub-Surface Reservoirs
The sub-surface reservoirs are very attractive and technically feasible alternatives for storing surplus monsoon run off. The sub-surface reservoirs can store substantial quantity of water. The sub-surface geological formations may be
