A bench comprising Chief Justice G Rohini and Justice R S Endlaw also asked the DJB to file a status report detailing the steps taken in this regard.
The court was hearing a PIL filed by Dwarka resident advocate S B Tripathi alleging that adequate water supply to his area has not been ensured due to non-laying of pipes water treatment plant in the area.
"At time of granting sanction to DDA for establishment of Dwarka sub-city, DJB had made clear way back in 1993 that DJB had no water to spare for Dwarka and DDA would have to make its own arrangement till DJB was able to do the same.
"Unfortunately DDA developed Dwarka without making any arrangement for Dwarka and is relying, even today, on water supplied by DJB from its Nangloi Water Treatment Plant," the petition claimed.
"Direct the DJB to supply an additional 2.20 MGD of water from Nagloi water treatment plant to DDA in Command Tank-2 at Madhu Vihar for Dwarka," the plea said.
