A new water treatment plant will be built in Chandrawal next year
A new water treatment plant is expected to open in Chandrawal by April 2023, according to Water Minister Satyendar Jain.
The plant will have a capacity of 105 MGD (million gallons per day) and is being set up at a cost of Rs 600 crore. The new plant will likely be able to handle ammonia levels of up to 4 ppm (parts per million) in water. The Delhi Jal Board’s existing water treatment plants can treat ammonia to a level of around 1ppm, while the BIS standard for ammonia in drinking water is 0.5ppm. High levels of ammonia in the Yamuna have in the past disrupted the water supply.
Two water treatment plants are currently operational in Chandrawal, one of 35 MGD and the other of 55 MGD, providing a total of 90 MGD of water. While the 55 MGD plant is also being redeveloped, a total of 160 MGD of water will be produced in Chandrawal once the new plant is ready. Work on the plant was halted for some time during the pandemic, Jain said, according to a communication from the DJB.
A “central water management centre” is expected to be included in the new Chandrawal plant to monitor water supply, distribution and pressure, according to the DJB.

Chandrawal water treatment plants supply water to areas such as Shadipur, Karol Bagh, Civil Lines, Malka Ganj, Patel Nagar, Sadar Bazar and Chandni Chowk.
With low water levels at the Wazirabad pond, from where the Chandrawal sewage treatment plant draws raw water, supply was hit from Friday morning, according to a note released by the DJB. The water level at the pond was 668.3 feet Thursday, compared to a normal level of 674.5 feet. Supply was also affected by the Wazirabad sewage treatment plant.
