Dikshit, who is also the Chairperson of the Delhi Jal Board (DJB), said the jal board would build 58 underground reservoirs, including 28 in east Delhi, in the Capital by 2009.

The Chief Minister, who was laying the foundation stone for a 58 lakh litre capacity underground reservoir at Narela in west Delhi, said the DJB has commissioned a city-wide study, which has created a workable model to commission 109 reservoirs by 2011.

“The total cost of construction of the reservoir is about Rs 782 lakh and this work is likely to be completed in 12 months. The reservoirs will improve availability and ensure pressure of water in various parts of Delhi,” Dikshit said.

The reservoir would get water from Ranney wells and tube wells at Palla, jal board officials said.

After this reservoir is commissioned, about 1.15 lakh people will benefit with augmented water supply at adequate pressure in Singhola, Singhu, Hamidpur, Bankuli and Khampur, the officials said.

“At least 25 underground reservoirs need to be built at various locations to rationalise the distribution of water in north, west, north-west, south-west and central Delhi. The DJB has already approved a scheme at an approximate cost of Rs 263 crore to construct 14 underground reservoirs and Booster Pumping Stations (BPS) at various locations in the Capital,” Dikshit said.
