Abstract

In order to determine the extent of groundwater overexploitation and investigate potential mitigation strategies such as artificial groundwater recharge, an investigation was carried out for each block in the district of Nadia, West Bengal. The current farming methods have irrigation water needs of 0.48 BCM, with the except the monsoon month. It was discovered that the ground water recharge was 0.48 BCM. Therefore, if ground water is completely sufficient to meet irrigation needs, 0.00042 BCM of ground water is discovered to be overexploited annually. The overexploitation of 2.73x10-4 m3 might be reduced if a 31830.13 m2 rooftop water collection structure and recharging facilities were built. The cost of this facility to build found Rs. 54.76 crore. The construction of this plant may potentially have a significant impact on the district's arsenic-contaminated ground water supply and the residential water supply.
