Groundwater is an important resource of the country, which is contributing substantially for the Indian economy. Nearly 80% of drinking and domestic water needs are met   through groundwater.   With more than 17 million energized wells nationwide, groundwater now meets more than 15% of the country's irrigation demand. The rapid development of groundwater utilisation has also brought in new problems, viz. over exploitation associated with quality deterioration, seasonal fluctuation of water table affecting shallow wells and also pollution problems.  

Quantification of natural groundwater recharge is a basic pre-requisite for efficient groundwater resource management and is particularly vital in arid and semi-arid regions.   In the present study, groundwater recharge is estimated for 59 rain gauge stations of Bangalore district using water-table fluctuation method for both monsoon and non-monsoon seasons.   The district receives 61mm average recharge, with a minimum of 49mm for Dodballapur taluk and a maximum of 75mm for Hoskote taluk.
