High ammonia hits water supply in city
New Delhi: Water supply in the capital was affected on Monday morning as the three water treatment plants in the city stopped working after high levels of pollutants were discharged in the Yamuna from Haryana.
DJB vice-chairman Dinesh Mohaniya, however, said the water quality had started improving by evening with Haryana releasing 2,000 cusecs of water to neutralise the pollutants. The situation is likely to be normal by Tuesday morning.
DJB said that water may be available in all parts of the city at low pressure, including south, west, central Delhi and NDMC areas till the situation improved completely.
Officials said ammonia levels in the Yamuna had increased to 3.2 milligram per litre on Monday morning due to dumping of pollutants in the river at Panipat reducing the efficiency of Wazirabad, Chandrawal and Okhla water treatment plants by 25%. The flow in Munak Canal and its sub-branch was also less, DJB said, adding that the public should make judicious use of water tankers.
