From the perspective of Global water scenario, it is evident that freshwater resources are discreetly spread and limited from the point of view of direct utility. Their utilization is high in different sectors such as agriculture, domestic, industrial and environment. In view of global population growth rate and increasing water demand it can be envisioned that fresh water scarcity is a global concern and this 21st century is confronting the same. This raises several challenges before future generation regarding sustainability of existing fresh water resources, an alternative option for freshwater resources and no compromise in water quality of resources to be used. India with second largest population in the world is no exception in water scarcity scenario. 54% of Indian water resources are reported to be scarce. The Central Ground Water Board (CGWB) as per Falkenman water scarcity index classifies India into critical, semi-critical and safe regions in addition to their findings of over-exploited, saline regions and unassessed hilly regions. This has accounted for physical water scarcity but economic water scarcity has not been accounted for. This study considers United Nation Commission on Sustainable Development on water scarcity index based on Annual Water Resource of India. This study put forward the water scarcity index blind to diversion of used water for various water utility sectors. However, consumptive use of water should be taken into account. Present study envisages to depend on alternative solution to water utility in present context of water scarcity in India as well as in global scenario to meet the future demand. The major problem in alternative water source is quality issue which can be overcome through application of various available technologies and arrive at a suitable solution.
