The PWD has identified 165 waterlogging spots and five hotspots across Delhi and is fully prepared to tackle the problem in these areas, PWD Minister Atishi said in April. They can monitor the situation,” he said. There are CCTV cameras installed at the pump house to monitor the situation and these are connected to the mobile phones of the area officials concerned. “But the problem has been resolved since then. If the water exceeds that level, the other will start,” he said.ĭuring the first monsoon showers last year, there was waterlogging as the pumps had not started functioning. If the water exceeds a metre, one pump will start to function. “These are automatic pumps with level sensors.
RAILROAD UNDERPASS MANUAL
The department has also removed manual intervention in the operation of these pumps. “The sumps also get filled with silt but the pumps have a system where they circulate a certain amount of water through a jetting system so that the silt does not accumulate, ensuring that no manual intervention is required,” he said. These positive displacement pumps have automatic screens that filter the waste materials from the water, the official said. The other issue was that the sewage would also contain polythene and other solid waste materials that would clog the pipes. The department has connected two pumps to a two-feet pipe which has a 600-mm diameter to flush out the water into an open drain, he added. There is space for future expansion and two more pumps can be installed if the need arises,” the official said. “A permanent pump house having six motors with a capacity of 100 horsepower each has been set up to drain out the water and clear the underpass. Speaking about the interventions made at the site, the official said a huge sump with 7.5-lakh-litre capacity was constructed and a separate pipeline laid to discharge the storm water into a nearby Municipal Corporation of Delhi drain. “The old pump house was a few metres away from the main road and by the time the water would reach the pump house through the pipes, the situation would have already spiralled out of control,” he said. During monsoons, all the sewage from the drain would overflow onto the roads, leading to waterlogging. According to a senior PWD official, waterlogging has plagued the site for nearly 20-25 years but the situation was aggravated over the last 10-15 years.Įxplaining the reason behind the worsening condition, he pointed to the presence of a Delhi Jal Board sewage pumping station at Khanpur.
