I have collected Figures for Groundwater and Waste Management in Delhi.
835 MGD- Current Supply of water.
100 MGD- extracted from ground by DJB.
1,216 MGD- Projected demand by 2020.
Sources of GROUNDWATER
3,167 traditional wells—4,57,977 bore wells and tube wells—611- 750 mm : Delhi’s annual rainfall.
When taps run dry ponds dry up, Haryana is not ready to give up an extra drop to Delhi, there will be only one reserve to bank on that’s GROUNDWATER.
