Delhis two major water treatment plants catering to 40 per cent of potable water supply in the city had to be shut down on Tuesday,after raw water from Haryana came laden with industrial pollutants.
The Wazirabad (120 MGD) and Chandrawal (90 MGD) water treatment plants had to be shut down at 6 am on Tuesday. On account of high level of pollutants in the river Yamuna,production at the Wazirabad and Chandrawal WTPs had to be stopped at 6.00 am, the Delhi Jal Board said in a statement.
The Haryana Irrigation Department was apprised of the presence of pollutants in the river water and was requested to release additional quantity of water at Munak to dilute the concentration of pollutants, the statement said. Due to high levels of ammonia in the water,the DJB has also advised residents to boil water before drinking.
DJBs member (water supply) B M Dhaul told Newsline that the water level at the Wazirabad pond had gone below the mandatory level on Monday. We had then contacted the Haryana Irrigation department to up water supply as the raw water supply at the Wazirabad pond had gone below the mandatory levels. On Monday evening,however,Haryana released a heavy flow of water,which came laden with industrial pollutants. The production had to then be stopped at the two WTPs, he said.
The DJB has now written to the Haryana Engineer-in-chief,as well as the Finance commissioner,asking about Haryanas efforts toward keeping the river clean and free of pollution. We have initiated the Rs 2,000 crore interceptor sewer project towards abatement of pollution in the river. Haryana is yet to respond on their efforts for treating the waste water flow into the river, Dhaul said.
The production at both the water treatment plants was partially restored at 5.00 pm on Tuesday, he added. Water supply to the affected areas would take time to normalise even after the two WTPs start full production. The loss of production has affected water supply to major parts of West,North,Northwest,Northeast and Southwest Delhi. While some parts of South and East Delhi were also affected,all areas under NDMC and Delhi Cantonment Board did not get any water supply on Tuesday.
A statement issued by the NDMC said: There will be no supply on Tuesday evening from the Jhandewalan,Talkatora,Hasanpur and all the other reservoirs of DJB. All areas,including MP flats,Parliament house,PM house and President house will be affected,including the adjoining areas.
