Owing to high level of ammonia in raw water supply from the Yamuna, the Delhi Jal Board (DJB) Monday shut down two water treatment plants at Chandrawal and Wazirabad. The move is set to affect potable water supply in various parts of the capital.
Stating that the Delhi government was in talks with Haryana on the issue, DJB Chairperson Kapil Mishra said, “Levels of ammonia has increased to 1.8 ppm. Water supply will not be available to residents today evening and tomorrow morning. The matter of pollutants entering the river course through the Panipat Drain has been taken up with the Haryana authorities concerned.”
The acceptable level of ammonia is 0.5 ppm, said officials. “If the level goes up, raw water cannot be treated. If the quantum of ammonia in raw water increases to 0.5 ppm or mg/l and beyond, the operation of raw water has to be suspended as ammonia when mixed with the treating agent chlorine gives rise to Trihalomethane which is carcinogenic in nature,” said Mishra

With these two plants supplying around 220 million gallons daily, various parts of central, north, northwest, west and central Delhi are likely to be hit with a shortage in potable water supply.
This is the second time this year that water supply has been hit in the capital owing to high level of ammonia. On January 19 and 20, the ammonia level had increased to 2.6 ppm, prompting Mishra to take up the issue with Union Minister for Water Resources Uma Bharti, asking for her intervention in the matter.
