The Delhi Jal Board announced on Sunday a water deficit in some sections of the national capital until November 1 due to excessive ammonia levels in the Yamuna. Several regions of east, northeast, and south Delhi, as well as territories administered by the New Delhi Municipal Council, will be affected, according to the report.
“The Upper Ganga Canal in Muradnagar, Uttar Pradesh, provides raw water to Delhi’s 110 MGD, or million (million jugs per day) Bhutan Water Therapy Plant (WTP) and 142 MGD Sonia Vihar WTP.” The Upper Ganga Canal was blocked from Haridwar on October midnight due to scheduled yearly repair by the Uttar Pradesh irrigated authority from October 12 to 31, according to the Jal Board.
“During the closure time, the Uttar Pradesh Irrigation Department and the UP Jal Nigam performed repairs and upkeep. As a result, Ganga water delivery to these WTPs has been discontinued,” it added. Until October 31, the WTPs rely on the Yamuna as an alternative source of raw water. However, the Delhi Jal Board stated that treating the Yamuna’s raw water is challenging due to its high ammonia concentration, which exceeds 1.5 ppm (parts per million).
Furthermore, production would be wholly dependent on the quality of raw water in the Yamuna, and output from these facilities would vary accordingly,” it noted. The Jal Board has encouraged Delhi residents to stockpile enough amounts of water in advance based on their needs and to utilize water wisely. Water tankers will be supplied on demand through the Jal Board’s helpline or central control room, it said.
