17 Sep : An area of 448760 sq. km. has been identified for Artificial Recharge to Ground Water out of the total geographical area of 3287263 sq. km. of the country. The total quantity of surplus monsoon runoff to be recharged has been estimated as 36.4 bcm through construction of 39 lakh artificial recharge and water harvesting structures.
In order to augment the depleting ground water resources, it is essential that the surplus monsoon runoff that flows into the sea is conserved and recharged to augment ground water resources. The Central Ground Water Board has prepared a concept report on “Master Plan for Artificial Recharge to Ground Water”, which aims at providing the area specific artificial recharge techniques to augment the ground water reservoir to accommodate it.
CGWB has prepared and circulated manuals and guides on artificial recharge to ground water, which provide guidelines on investigation techniques for selections of sites, planning and design of artificial recharge structures, economic evaluation and monitoring of recharge facility.
