摘要：Water is a precious natural resource which replenishes each year through monsoon rains. Most of theareas in India are facing severe scarcity of water for drinking, irrigation and industrial needs of thesociety. The crisis of water resources, the development and their management is of great importancebecause, the required quantity of the water is not available for use due to uneven spatial distribution.In India, groundwater is the main source of irrigation and water supply needs. Excess use ofgroundwater for irrigation has adversely affected drinking water supply needs in recent years, whichhas a direct impact on the quality and quantity of groundwater. Better water/groundwater managementpractices and planning for artificial recharge of groundwater can only improve the sustainability ofgroundwater resource in coming years. Like in other places of India, in Karnataka, particularly in Malurtaluk in Kolar district, is not having any major surface water bodies to cater to the irrigation anddomestic water supply needs of the people. The entire area is by and large totally dependent ongroundwater for irrigation, domestic and industrial water supply needs. Due to continuous withdrawalof groundwater to meet the demand, dug wells tapping the phreatic aquifers are totally dry since lasttwo decades, which has tremendous impact on phreatic aquifer system, surface water bodies andrural water supply schemes in the area and also on the quality of groundwater. Better groundwatermanagement practices coupled with artificial recharge to groundwater are the options left forsustainability of groundwater resource in the area. Roof top rain water harvesting is also essential tomitigate the drinking water needs of the people in the area. Drip irrigation and sprinkler irrigation in largescale can control the depletion of groundwater level in the area.
