The water conservation science or the technique of rainwater harvesting is a deep-rooted tradition from ancient India. The environmentally sustainable conventional systems are feasible and cost-effective alternatives for revitalizing India’s degraded water resource management. The solution to India’s chronic water distress may be to merge the infrastructure efficiently with up-to-date rainwater harvesting methods such as storage reservoirs, injection wells, and sub-surface barricades. Research emphasis on rain-water harvesting isrequired to boost its contribution to a sustainable environment for agricultural and food production. Rain-water harvesting system plays a major role in climate change, though it will have less impact in arid regions. It reduces the uncertainty of domestic water in arid areas, and improves internal water safety. For the proper application of a rain-water harvesting system, effective socio-political policies and community mass awareness should be put in place. rainwater pools in large storage tanks during the rainy period, which helps to reduce flooding in low soil areas. Low cost and quick depletion of artificial groundwater would help to raise the depleting layer of the water table. The world’s highest groundwater withdrawal is India, with population growth leading to an increase in water necessities, good withdrawal among several carriages of stakeholders, a danger of significant reduction in numerous Indian zones.
