According to officials , the pollution spike has impacted operations of the Wazirabad and Chandrawal water treatment plants (WTPs) where the operations are curtailed by 25% to 50% levels. Both Wazirabad and Chandrawal WTPs directly draw water from Yamuna through Wazirabad pond and supply treated potable water to parts of north, central and south Delhi.

Delhi Jal Board (DJB) on Wednesday said that due to regular receipt of high pollutants in river Yamuna at Wazirabad pond, the water production has been affected by 25-50% at Wazirabad & Chandrawal WTPs. “Therefore, water supply will be available at low pressure till the situation improves. Public is advised to make judicious use of water and water tankers shall be available on demand from DJB helpline, 1916,” said the statement issued by DIB.
