Abstract:
According to the 2019 statistics, the population of India is likely to be around 135 crores. The large quantity of water will be needed to meet the food and other needs of this large population. To meet the water requirements in future, the sources of water will have to be used in a very careful way. Although, India comes at the third place in the world, as far as the number of big dams is concerned. Despite storing so much water, there is a shortage of water during summer days. To meet the water requirement, groundwater is being used excessively, due to this; the groundwater has gone down drastically. The Government of India has taken up the task of rainwater harvesting, renovation of traditional and other water bodies/tanks, reuse, bore well recharge structures, water shed development and intensive forestation in 1592 water stressed blocks of 256 districts in the country in a big way under the Jai Shakti Abhiyan. In the coming years, this scheme will show its benefits resulting in an increase in the groundwater level. A coastal reservoir is a fresh water reservoir in the seawater near a river mouth to capture the sustainable river flow. It provides water by storing it from the river discharge and runoff which otherwise will flow in the sea. The water in the coastal reservoir can be used for drinking, irrigation or industrial purposes.
