Yamuna pollution level reduces, two water treatment plants resume full production

Indian Express, 15 January, 2014


DJB assures all the residents of Delhi that water being supplied by the Board is wholesome and potable.


NEW DELHI: A day after production at two of Delhi’s major water treatment plants had to be curtailed by 50 per cent after raw water from Haryana came laden with industrial pollutants, the water utility announced resumption of normal production on Tuesday as the pollutants were diluted.


“The matter of rise in pollution in the Yamuna from the Panipat drain was taken up strongly by Delhi Jal Board with the Central Pollution Control Board (CPCB) and the Haryana Pollution Control Board. As a result, the pollution in the Yamuna at the Wazirabad pond has started receding since morning. This has enabled DJB to restore normal production at both Wazirabad and Chandrawal water treatment plants,” a statement issued by the DJB said on Tuesday.


Production at the 120-mgd Wazirabad plant and the 90-mgd Chandrawal plant had to be curtailed by 50 per cent on Monday on account of high level of pollutants in the river Yamuna — the level of ammonia recorded in the river on Monday was 1.2 ppm against permissible limit of 0.2 ppm. The two plants cater to 40 per cent of the potable water supply in the city.


While water supply to NDMC areas, Central, Old, North and parts of South Delhi was affected till Tuesday evening, DJB officials said normal supply will be restored by Wednesday morning.


“DJB assures all the residents of Delhi that water being supplied by the Board is wholesome and potable,” a statement issued by the Jal Board said.


Indiscriminate discharge of industrial and domestic waste into a drain in Panipat (drain no. 8) is said to be the root cause of periodical discharge of excessive pollution into the river.


In 2011, the then environment minister Jairam Ramesh had asked Haryana to set up a sewerage treatment plant at Panipat and link all its pollution-generating industries to the common effluent treatment plant (CETP). Only about 50 of the 512 pollution-generating industries in Panipat are linked to the CETP
