Delhi: Rain catches city off guard again | Latest News Delhi

New Delhi Strong winds and rain caused heavy traffic disruptions to office travelers across Delhi and the National Capital Region (NCR) on Monday, with reports of waterlogging at several arterial points and uprooted trees.

Heavy traffic and heavy traffic were reported at key places like IIT Delhi intersection, Pul Prahladapur Underpass Hauz Khas, Rao Tula Ram Road overpass near Vasant Vihar, Ashram Chowk, Najafgarh Road, Nangloi Road and Bakarwala intersection.

The thunderstorm, which caused chaos, served as a wake-up call to agencies when raising questions about the city’s monsoon readiness – about the need to speed up their desalting operations and completely redesign them. .

With weather extremes becoming more volatile and heavy rainy days at any time of the year is now a reality, experts say the pre-monsoon preparations should make way for year-round activity. City drainage networks, public health-related drives and emergency response.

Work on clearing the drainage network is expected to be completed by June 15, 2022, according to the ongoing distillation action plans of the relevant agencies. Municipal corporations in Delhi (now under the consolidated MCD) have claimed that 66% have been removed. The proposed sludge volume and 60,000 metric tons of sludge were sent to landfill. The former Southern corporation oversees 185 km of 275 major sewers, the Northern MCD 815 drains 459 km and the Eastern Corporation 218 drains 120 km. – All of them now come under a consolidated corporation.

The Department of Public Works (PWD) officials under the Delhi government, who are currently working on the 50% level in various sectors, have a deadline of June 15. The Department of Public Works (PWD) covers the 2,064.08 km hurricane. Turn off the system.

To be sure, Delhi has 11 different agencies that oversee 426.5km natural drainage lines and 3,311.5km engineered rainwater drains and a large number of agencies are often blamed for poor management of the drainage network.

Delhi’s four-decade-old drainage project also needs to be urgently renewed, with many promises made but little progress has been made on the ground.

The process of recruiting consultants for the implementation of the drainage master plan has not begun, but a senior PWD official said. The process is now being revised, the official said. In March, the Delhi government announced that it would appoint two consultants to prepare a blueprint for enhancing existing drainage systems and overseeing the implementation of the new master plan.

“For technical reasons we had to cancel the first tender call and the bidder’s technical proposal was not adequate in the second attempt. To increase the number of participants, we withdrew the tender process,” the official said, asking not to be named.

While the drainage master plan process may take some time, corrective measures will be implemented before the onset of the monsoon at 13 critical aquatic sites in Delhi, a second PWD official said. “This includes the Pull Prahladpur Underpass, which is frequently witnessed, the 600,000 liter capacity underground tank and the logging of the water where a new pump house is being installed,” said the second officer.

Chandra Bhushan, climate change expert and CEO of iForest, says that climate anomalies have become more common over the past decade, with extreme heat often leading to severe rainfall.

“The first two months of the year saw heavy rains and the next two intense heat. Therefore, such a strong spell was expected, and if that happens, the infrastructure of the city will collapse because Delhi’s existing sewerage system is incapable of handling even moderate rainfall,” Bhushan said.

He said there is a need to work on systematic and infrastructure changes, which should be addressed year-round. “One cannot undertake distillation alone for a couple months and expect results. The whole exercise is worthless.

In April, the Special Task Force urged all drain-owning agencies to do a year-round exercise rather than setting pre-monsoon targets to combat mosquito-borne diseases.

According to the current method, the deadline for May 31 or June 30 is usually set to meet the annual declining targets, according to a senior MCD official. “This method does not work with unlimited rainfall. The aquifer allows for greater mosquito reproduction and increased vector density. We need to modify these action plans to exercise year-round, ”the official said on condition of anonymity.

Rainfall data show that weather anomalies and unexpected rainfall are on the rise. This led to the Delhi waterfront also in the winter months of January and February, two instances in January this year (January 7 and 22) and one in February (February 8).

In January, Delhi recorded 88.2m rainfall, the highest in January for the past 121 years, beating the 1989 record (79.7mm). The city witnessed seven Western disturbances in February, not only inspecting both highs and lows but also bringing a total of 29.7mm of rain, the highest since February 2014.

Delhi’s sewer system can only deliver 50mm of rain a day, and more than that, overflowing the system, causing arterial roads and heavy traffic jams. Nine such heavy rainy days have been observed in 2021 with more than 50mm of rainfall. Last year, Delhi recorded 1,512.4 mm of rainfall till December 29, the second highest so far (1,534.3 mm in 1933).

Gufran Beg, Founder Planning Director of Safar, an agency under the Ministry of Earth Sciences, says severe rainfall is more common during non-monsoon months and Delhi is no exception. This is likely to put additional burden on existing infrastructures, so better preparation is needed. “We need two things. One is the alert system for such weather extremes and two, the year-long inter-departmental coordination in combating these incidents and preparing them, ”he said.

A senior municipal official said the civic body had been working on the warplanes to meet its goal of cleaning up all its sewers before the onset of monsoon. “Before the June 15 deadline, the corporation will complete all sewage removal. We have appealed to the Department of Irrigation and Flood Control of the PWD, DSIIDC and the Delhi Government to complete the cleanup of all sewers in their jurisdiction before the onset of monsoon, which will reduce civilian disturbances during the rains as most sewers in the city are interconnected.. “

A Delhi government spokesman has not responded to the request.
