Day after rise in Yamuna’s ammonia levels, Delhi water treatment plants back to running at 90% capacity

Sources at the Delhi Jal Board said that the plants had been functioning at around 50% of their capacity on Saturday. From the time that pumping is disrupted, it can take around 18 hours for the plants to begin operating at normal capacity and for supply to return to normal levels, the sources added. As such, water supply has been disrupted across several areas of Delhi.

Among the plants that were hit include Sonia Vihar, Wazirabad, Okhla, Bhagirathi and Chandrawal. On Sunday morning, the Sonia Vihar plant was running at 95%-97% of its capacity, while the plant at Wazirabad had returned to operating at around 98% of its capacity. The Bhagirathi water treatment plant was functioning at around 93%-95% of its capacity. The plants are expected to return to functioning at its full capacity by the end of the day, the sources said.
