New Delhi: High Ammonia levels in Yamuna because the disposal of pollutants from Haryana caused 50 percent of production reduction at Wazirabad, Chandrawal and Okhla which would affect supply in several parts of the national capital, officials said on Wednesday.
WTPS in Chandrawal, Wazirabad and Okhla can take care of up to 90 million gallons of water a day, each 135 MGD and 20 MGD.
