Abstract

Rural households of North 24 Parganas district, West Bengal (India), suffer twofold water-related problems, viz. supply of contaminated groundwater and waterlogging due to excessive rainfall for the last four decades. The present study deals with a mixed mode approach encompassing physical, socio-economic, and hydrogeological aspects to assess the water scarcity and feasibility of RWH among four blocks of North 24 Parganas, India. A hydrogeological cross-section (Fench Diagram) was developed to assess the potential of artificial recharge followed by the identification of artificial recharge sites with suitable structures using RS and GIS. Water quality parameters like TDS, ammonia-N, and chloride were found within the respective safe limit prescribed for drinking purposes in the water samples. The extent of water stress was assessed by a socio-economic survey conducted for rural households. Rural households expressed their willingness to adopt RWH subject to certain conditions. The LULC study showed a rapid increase (21.69%) in the built-up area during 2010–2020. The capacity of the storage tank was calculated as 6000 l for individual rural households. Sixty grams of disinfectant was suggested for the treatment of the harvested rainwater. The methods suggested would help local authorities execute successfully the RWH schemes in water-stressed areas.

基于水文地质和社会经济方面的考虑，在印度北 24Parganas 的定性和定量缺水地区进行人工补给雨水收集的选址和存储系统设计

印度西孟加拉邦北 24 帕尔干纳斯区的农村家庭在过去 40 年中遭受着双重用水问题，即受污染的地下水供应和过量降雨造成的内涝。本研究采用混合模式方法，包括物理、社会经济和水文地质方面，以评估印度北 24Parganas 地区四个区块的缺水情况和 RWH 的可行性。首先绘制了水文地质断面图（芬奇图）以评估人工补给的潜力，然后利用 RS 和地理信息系统确定了具有合适结构的人工补给点。发现水样中的 TDS、氨氮和氯化物等水质参数均在规定的饮用水安全限值范围内。对农村家庭进行的社会经济调查评估了用水紧张的程度。农村家庭表示愿意在满足某些条件的情况下采用 RWH。土地利用、土地利用变化（LULC）研究显示，2010-2020 年期间，建成区面积迅速增加（21.69%）。根据计算，农村家庭的储水箱容量为 6000 升。建议使用 60 克消毒剂处理收集的雨水。所建议的方法将有助于地方当局在缺水地区成功实施 RWH 计划。
