Showing signs of sustainability, the city recharged more groundwater than it extracted in FY 2021-22, according to a report by Central Ground Water Board (CGWB). This is the first time since at least 2009-2010 that the city's recharge is more than its extraction. The report, titled 'Dynamic Ground Water Resources Assessment of India - 2022', said compared to 2020-21, the total annual groundwater recharge increased from 0.32 bcm (billion cubic metres) to 0.41 bcm. The annual extraction, including artificial and due to natural discharge, went up too, from 0.322 bcm to 0.4 bcm. Therefore, overall, extraction decreased from 101.4% to 98.1%. The study highlighted some concerns too.
