Delhi: work to prevent congestion in the Pul Prahaladpur underpass, 15 critical points
After the Minto Bridge, the Public Works Department (PWD) has decided to turn its attention to another critical place in the city that gets waterlogged during the monsoon: the Pul Prahaladpur underpass. The department is constructing an underground sump with a capacity of 7.5 lakh liters and a permanent 600 horsepower (HP) pumping station to evacuate the water.
According to officials, the construction of the underground sump and pumping station should be completed by the end of this month. The department is also installing seven temporary pumps, with a total capacity of 500 hp, which will suck up the water.
An official added: “Rain or not, the Pul Prahaladpur underpass remains clogged throughout the year due to the low capacity and poorly maintained main line which discharges water into the main storm drain. . But the situation becomes critical during the monsoon.
“During the last monsoon, a man drowned and we had to close the whole underpass. However, we already have a 500 HP water pump and the department is also installing a storm drain, which will have the capacity to discharge 60 lakh liters of water per hour,” the official added.
In addition, the PWD is installing alarms and CCTV cameras to closely monitor the area, officials said. The executive engineers as well as the relevant junior engineer will monitor the drainage capacity around the clock on their phones through a live stream. Also, if the water level exceeds the allowable limit, alarms will alert pump operators to remove the water or turn on the pumps, they added.
Apart from this, the department has also selected 15 other critical locations including Zakira flyover, Azadpur underpass and IP Estate ring road and identified 147 waterlogging hotspots where de-silting works are ongoing. .
“During the monsoon, waste from the temporary drains built by the railways block the Zakira underground passage. Because of this, the water pumps clog and cause clogging of the area. So we decided to install screens and modify the drains to avoid the clogging problem,” an official said.
Another critical location experiencing significant congestion is IP Estate Ring Road, opposite the WHO building. Here, the department plans to construct a 1.5 liter sump and storm drain from the old IP power station to the Yamuna River and nine temporary pumps will also be installed to suck the water immediately.
The PWD is also preparing an action plan to prevent congestion at Jahangirpuri metro station, including the construction of a drain as well as a service road. The remodeling of a storm water drain and the construction of a permanent pumping station were also included in the action plan.
“Although the Minto Bridge drainage lines are quite old, we have solved the endless problem of waterlogging in the area and there have been no major waterlogging incidents in the past year. The department is working at full speed to repair and desilt the drains to prevent waterlogging and accidents on the PWD roads this monsoon,” the official said.
Apart from this, the degritting work of storm sewers in Delhi is also proceeding at a rapid pace. Deputy Chief Minister Manish Sisodia ordered officials to complete the desilting of all drains by May 31.
“The desilting of all drains on PWD roads is in progress. The work will be completed before the monsoon arrives,” an official said. The department maintains about 1,400 km of main roads in Delhi.
