GUIDE IN ARTIFICIAL RECHARGE TO SURFACE WATER
1 . 0 INTRO
The unnatural recharge to ground normal water aims at enlargement of ground water reservoir by adjusting the all-natural movement of surface normal water utilizing appropriate civil structure techniques. Artificial recharge approaches normally treat to following issues (i) To enhance the sustainable produce in areas where over-development has depleted the aquifer. Preservation and storage area of excessive surface drinking water for long term requirements, as these requirements often adjustments within a period or a period. To improve the standard of existing floor water through dilution. To take out bacteriological and also other impurities via sewage and waste normal water so that normal water is suitable for reuse.
The standard purpose of artificial recharge of ground water is to reestablish supplies via aquifers exhausted due to increased ground drinking water development.

Concept of Augmenting Ground Normal water Reservoir Floor Water or Sub-Surface Reservoirs
The sub-surface reservoirs are incredibly attractive and technically feasible alternatives intended for storing excess monsoon elope. The sub-surface reservoirs can easily store significant quantity of water. The sub-surface geological formations may be considered as " warehouse" for saving water which come from options located on the area surface. Besides suitable lithological condition, additional considerations for producing sub-surface storages are great geological constructions and physiographic units, in whose dimensions and shape enables retention of substantial volume of water in porous and permeable composition. The sub-surface reservoirs, positioned in suitable hydrogeological situations, will be environment friendly and economically feasible proposition. The sub-surface storages have advantages of being free of the negative effects like inundation of large surface area, loss of cultivable land, displacement of local population, substantial evaporation loss and tenderness to earthquakes. No enormous structures are needed to retail outlet water. The underground storage area of drinking water would also have beneficial affect on the existing ground water regime. The deeper normal water levels in several parts of the country, either of natural occurrence or perhaps due to abnormal ground water development, can be substantially increased, resulting in lowering of lifting costs and economical. The quality of normal ground
drinking water would significantly improve in brackish and saline areas. The avenue function of aquifers thereby reducing the cost intensive surface water conveyance system. The effluence as a result of such sub-surface storage in various area intersection details in the form of planting season line, or perhaps stream emergence, would boost the river moves and improve the presently degraded ecosystem of riverine tracts, particularly inside the outfall areas. The constructions required for recharging ground water reservoirs happen to be of tiny dimensions and cost effective, such as check public works, percolation reservoirs, surface spreading basins, pits, subsurface dykes etc .
