The Delhi Jal Board has announced that a new 105 million gallons per day (MGD) water treatment plant at Chandrawal has been completed, with the project expected to strengthen water supply for about 22 lakh residents across central and northern parts of the capital.
The plant has been built at a cost of more than Rs 598 crore, according to information shared by the Delhi Jal Board. The board said the modern facility will replace the older Chandrawal-I and Chandrawal-II treatment plants. The announcement was made through a post on the board’s official X account.
The areas identified as beneficiaries include Sadar Bazar, Chandni Chowk, Matia Mahal, Ballimaran and Karol Bagh, along with other adjoining locations. The Delhi Jal Board has described the new facility as a capacity addition intended to make supply stronger in these parts of the city. The announcement did not specify the date on which full commercial operation or commissioning of the replacement plant would begin.
The Chandrawal project is part of Delhi’s continuing effort to expand and modernise its water treatment capacity. Replacing older plants at an existing water infrastructure site also links the project to the reliability of the distribution network, since treatment capacity alone does not determine how much water reaches individual neighbourhoods. The board’s announcement focused on the plant’s capacity, cost and expected coverage; details on the implementation schedule and changes to local supply timings were not provided in the information available.
The water utility has recently also shared details of a separate 2 MGD recycling plant at Bawana, built at a reported cost of Rs 13.48 crore. The Bawana facility is intended to treat high-turbidity water flowing through drains to drinking-water standards, according to the information cited in the report. It is a separate project from the Chandrawal treatment plant.
The Chandrawal announcement comes as the Delhi Jal Board manages supply during maintenance-related changes in the wider water system. The Upper Ganga Canal was scheduled to remain closed for maintenance until 8 November, with the Uttar Pradesh Irrigation Department carrying out the annual work. The canal supplies Ganga water to the Delhi Jal Board’s Sonia Vihar and Bhagirathi water treatment plants, where it is treated before distribution.
In a public notice cited in the report, the Delhi Jal Board said water supply would continue uninterrupted in all affected areas during the canal maintenance period and that residents would not face inconvenience. The board’s statement on the Chandrawal plant identifies the five named neighbourhoods and other areas as the main beneficiaries, but does not provide a ward-wise breakdown of the expected supply improvement.
The next operational milestone is the plant’s commissioning and integration with Delhi’s distribution network. The Delhi Jal Board has not, in the information available, announced a specific date for that step or provided details of how supply will be managed while the older Chandrawal plants are replaced.
