New Delhi: A day after taps went dry in parts of the capital, the Delhi Jal Board (DJB) on Tuesday said that water supply will resume only by Wednesday morning as the level of ammonia in Yamuna waters continued to remain above permissible limits.
The water supply in north, central, west and south Delhi was affected as two water treatment plants at Wazirabad and Chandrawal have been shut since Monday evening following high levels of ammonia in the Yamuna waters.
"The limit of ammonia in water has increased to 1.4 part per million compared to the required 0.6 parts per million", R.K. Garg, engineer-in-chief and member of the DJB, told reporters.
Garg said the ammonia level has been rising since Monday afternoon but the situation is expected to improve by Tuesday evening as it is expected to drop to 1.2 parts per million.
"We have started the cleansing operation and 1,000 cusec of water is being flushed out. By night, the ammonia level will be within the permissible limits and water supply is likely to resume Wednesday morning", he said.
The DJB attributed the rise in ammonia levels to the increase in pollutants being released in the Yamuna by Haryana.
"The matter has been taken up with Haryana several times in the past through the CPCB (Central Pollution Control Board). An effective response is expected from them so that this doesn`t happen again", DJB chief executive officer Ramesh Negi said.
