For the third time in a row in the last 10 days, ammonia levels went up in the Yamuna, prompting Delhi Jal Board to curb production at two major water treatment plants. The water utility also took up the issue to the Upper Yamuna River Board on Tuesday. Water supply would be disrupted in some parts of South, North and Central Delhi, along with NDMC areas.
Apart from the New Delhi area, others which would be affected include Vasant Kunj, Malviya Nagar, Greater Kailash, Model Town, Civil lines and Sadar Bazar. “The ammonia level at Wazirabad pond rose beyond permissible limits, forcing DJB to reduce production by 25 per cent at two of its Water Treatment Plants (WTPs) at Wazirabad and Chandrawal,” said a DJB official. The permissible level of ammonia in raw water is 0.2 parts per million (ppm) but officials said that since the past 12 days, levels have not dropped below 0.5 ppm. To discuss the matter, Chief Minister Arvind Kejriwal was scheduled to meet Haryana CM Bhupinder Singh Hooda on Monday during a meeting of the NCR Planning Board, but Kejriwal was busy with his dharna during that time.
