FY 2021-22 & 2022-23: Delhi recharged more groundwater than it extracted^[1][2]

FY 2021-22: This is the first time since at least 2009-2010 that Delhi's recharge is more than its extraction^[1:1]

¶ Comparison with previous years

*_{bcm = billion cubic metres}

¶ FY2021-22 Comparison to 2020-21^[1:4]

Net extraction decreased from 101.4% to 98.1%

• Annual groundwater recharge increased from 0.32 bcm (billion cubic metres) to 0.41 bcm

  • Refinement of data on piped water supply and increased piped piped water supply by DJB in many areas led to an increase in recharge due to return seepages

• Annual extraction, including artificial and due to natural discharge, went up too, from 0.322 bcm to 0.4 bcm

  • The increase in groundwater extraction can be attributed to refinement in the database. About 12,000 private tubewells, which have been registered with DJB, have been incorporated in the estimation
