The water supply in Delhi, India has decreased by 25% due to polluted water containing industrial waste.
According to the Arvind Kejriwal government, the water supply in Delhi, India has decreased by 25% due to polluted water containing industrial waste.
The waste was released from Haryana and has affected water treatment plants in the national capital. The industrial waste coming from water released from Haryana and Badshahpur drain are mainly responsible for the rising pollution level in the Yamuna River, according to Mint.
According to Delhi Health Minister Satyendar Jain, polluted water is being released from Haryana and ammonia levels in the water have risen due to release of industrial waste. Ideally, ammonia concentration in water should be around 0.8 ppm, but it is currently around 2 ppm.
"The water treatment plants will not be closed, their efficiency has been slightly reduced so that the ammonia in water can be treated," added the minister.
The National Green Tribunal (NGT) requested a report from the Central Pollution Control Board, Delhi Pollution Control Committee and Industries Commissioner about the reasons behind the sudden increase.
Raghav Chadha, the vice-chairman of Delhi Jal Board (DJB), said that due to an increase in pollutants in raw water discharged from Haryana, the water supply will be affected in parts of west, north, central & south Delhi areas.
“We endeavour to restore normal water supply ASAP. Please use water judiciously,” tweeted Chadha.
DJB officials blamed the industries in upstream Panipat section of Haryana and low levels of water being released from DSB/CLC canals for the current situation, reported the Times of India.
“In the last three months, around 2,000-3,000 cusecs of water was being released due to which dilution of raw water was happening. Now, less water is being released and industrial pollutants are back in the river water,” said an official.
