Assessment of the Domestic Water Scarcity Using Supply-Demand Balance Index
Abstract: Semi-arid regions undergoing rapid urbanization are increasingly vulnerable to domestic water scarcity due to population growth, changing living conditions and limited water resources. Shrigonda, a small town in Maharashtra, is typical in that it experiences seasonal domestic water scarcity due to growing demand and a limited, uneven water supply. Adapting the Supply-Demand Balance Index (SDBI), this research evaluates the domestic water scarcity in Shrigonda wards in 2019 by combining population projections, domestic water demand estimates and monthly water supply data. This study shows that during the water-stressed summer months (March-May), all nine wards experience moderate to acute domestic water scarcity (SDBI values are typically below 0.9 and, in some cases, below 0.6, indicating acute scarcity). By contrast, during the monsoon and post-monsoon seasons, most wards achieve SDBI values of 1 or greater, indicating no water scarcity. Such findings establish significant intra-annual and spatial variations in domestic water supply within the town and the need for measures such as water demand management, augmentation of source supply, and decentralized measures, such as rooftop rainwater harvesting, to enhance domestic water security.
