The water crisis that has been plaguing the Capital since last Friday is threatening to get worse. Several parts of north, northwest Delhi and NDMC areas have been getting a highly erratic supply and authorities see no respite from the situation till the end of this week at least. The matter has been taken to the Upper Yamuna River Board and chief minister Sheila Dikshit will take up the issue with authorities concerned if the situation doesn't improve soon. The 120 million gallon per day (MGD) Wazirabad plant and the 90 MGD Chandrawal plant are working to only about 70% of their capacity as Haryana, claim Delhi Jal Board officials, has reduced supply to the Capital from 300 MGD to about 250 MGD.
