The Delhi Water Board (DJB) said on Thursday that water supply in several parts of Delhi would be affected from Friday morning as the level of Wazirabad pond had dropped due to low water discharge in the Haryana Jamuna.
The acute water crisis comes at a critical stage as the capital looks toward heatwaves as mercury is forecast to reach 46-47 degrees Celsius this week.
Haryana supplies 610 million gallons of water per day to Delhi through two canals along the Jamuna – Carrier-Lined Channel (CLC) and Delhi Sub-Branch (DSB).
On Wednesday morning, the water level at Wazirabad Barrage dropped to 62.30 feet against the normal level of 64.5 feet. The flow of raw water in the Carrier Line Canal (CLC) has been reduced from 683 cusecs to 566 cusecs, according to PTI.
The low level of Wazirabad pond and low flow of CLC has reduced the efficiency of water treatment plants at Chandrawal, Wazirabad, Haiderpur, Nangloi and Dwarka.
The capacity of Chandrawal and Wazirabad water treatment plants is 90 MGD and 135 MGD respectively. The two plants draw raw water from the Wazirabad pond, purify it and supply it to Delhi Cantonment and New Delhi Municipal Council areas, including North-East Delhi, West Delhi, North Delhi, Central Delhi and South Delhi.
The Aam Aadmi Party government had earlier written letters to the Haryana Irrigation Department on May 3 and April 30 to increase the flow of water in the Jamuna.
CLC and DSB supply water from Hathni Kund through Munak Canal and Bhakra Beas Management Board. Delhi needs about 1,200 MGD of water, while DJB supplies about 950 MGD
In addition, the Indian Meteorological Department has issued a ‘yellow’ warning, warning of heatwaves on Friday and Saturday. An ‘orange’ warning was issued on Sunday to warn people about the intense heat wave.
