In the midst of heavy rains in both the nation’s capital and the higher parts of the Yamuna River, the water level in Delhi crossed the danger mark once more on Wednesday morning, less than 12 hours after it went below the threshold.
According to data from the Central Water Commission, the water level at 8 am was 205.48 metres. By 6 o’clock, it should have risen to 205.72 metres.
On Tuesday afternoon, the flow rate at the Hathnikund barrage slightly increased and varied between 50,000 and 60,000 cusecs.
By Wednesday morning at 7 a.m., it had decreased to about 39,000 cusecs. 28.32 litres per second are contained in one cubic second.
Up till July 22, isolated locations in Uttarakhand and Himachal Pradesh might expect heavy to very heavy rain, and Delhi will have moderate showers on Wednesday.
By 8 p.m. on Tuesday, the river’s water level had decreased below the danger threshold of 205.33 metres after eight days of flowing over it. At 5 a.m. on Wednesday, it had retreated to 205.22 metres before beginning to rise once more.
The rise in water levels may make it harder for impacted people to rebuild their homes in the capital’s low-lying regions, forcing them to stay in relief camps for an extended period of time.
It might also have an effect on the water supply, which was disrupted for four to five days due to the flooding of a pump house in Wazirabad and finally returned to normal on Tuesday.
The Wazirabad, Chandrawal, and Okhla water treatment plants, which together provide around 25% of the city’s supply, receive raw water from the pump house.
On Friday, the Okhla water treatment plant went into operation. On Sunday, Chandrawal, and Tuesday, Wazirabad.
According to a Delhi Jal Board (DJB) employee on Tuesday night, “There is a shortage of only 10-12 million gallons of water per day (MGD) due to inundation of some tube wells in the river floodplains at Palla.”
The DJB uses tubewells set up in the Palla floodplains to extract about 30 MGD.
