Delhi Jal Board to install 11-km pipeline to fix ammonia woes in city

NEW DELHI: Delhi Jal Board will start a project to install an 11-kilometre pipeline, aiming to resolve intermittent water supply issues in Delhi caused by elevated ammonia concentration in the Yamuna.The department is working on the specifications and the expenditure projections for the Rs 300-crore infrastructure initiative. The planned water conduit will connect from the Haiderpur Water Treatment Plant (WTP) and extend up to the Wazirabad barrage.Water minister and Delhi Jal Board (DJB) chairperson Parvesh Verma said: "Under the leadership of PM Modi, we are working to ensure that the capital does not face a water crisis even in extreme summer, and this initiative is in that direction." He said the proposal was passed in the board meeting of DJB held recently.The proposed pipeline will supply raw water, if required, to reduce ammonia levels in the Wazirabad pond. This will also help in situations when drawing raw water from Wazirabad should be avoided. A 2,400-millimetre diameter pipeline will be laid from the DJB's Haiderpur water treatment plant, which gets its raw water from the carrier line channel (CLC), also known as Munak canal, that runs from Karnal in Haryana to Haiderpur, said an official.This line provides around 680 cusecs of raw water to several other water treatment plants.A senior official said that Delhi Jal Board is addressing concerns regarding ammonia content in the Yamuna, which carries Delhi's allocated water supply from Haryana through the Wazirabad barrage. The initiative focuses on managing ammonia concentration in the Yamuna that affects the operations at Wazirabad and Chandrawal water treatment plants. This undertaking will be implemented as part of the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) programme by central govt.It is likely to be completed in two years, the official said.The design of the plants is such that these cannot treat raw water that contains more than 1 part per million of ammonia. The raised ammonia levels in the river water in recent days, sometimes touched 5 ppm, causing reduced water production and supply.Verma recently also said that directions were given to carry out desilting work that will double the storage capacity. He said that the desilting process would be completed within one to one-and-a-half months, after which the plant would be able to store water at double its current capacity. He said this while inspecting the Wazirabad plant, during which he also drank the treated water.New Delhi: Delhi Jal Board will start a project to install an 11-kilometre pipeline, aiming to resolve intermittent water supply issues in Delhi caused by elevated ammonia concentration in the Yamuna.The department is working on the specifications and the expenditure projections for the Rs 300-crore infrastructure initiative.
