At present Delhi has allocation of waters from the Yamuna, the Ganga and the Beas [Bhakra project], in addition to ground water resources, with the total availability, as follows:

The above capacity can be reinforced through the following means:

1. Flood plain reservoirs at Wazirabad. Barswal. Badapur. Nala Mandela and at Nizamuddin bridge providing additional 0.168 BCM.
2. Rain water reservoirs at Tilpat/ Tughlakabad 0.010 BCM
3. Reservoirs in the NCR at Najafgarh Jheel and Hindon-Ganga bed with the capacity 0.285 BCM.
4. Harvesting in existing tanks and wells to the extent of 0.010 BCM
5. Revival of dried up streams [through afforestation] of Delhi with capacity 0.015 BCM
6. Increased ground water output in government and private wells due to better recharge of aquifers through greater flow in river Yamuna, yielding additional 0.033 BCM
7. Greater output of treated sewage of higher quality in 9 eco-parks designed by Paani Morcha to the extent of additional 0.500 BCM.

It can be seen that the above measures would yield an additional 1.011 BCM of usable clean water, giving Delhi sufficient waters to meet its increased requirements of the next century and obviating the need to bring Tehri dam waters to Delhi
