The eastern suburb of Mulund received 144.01 mm of rain in three hours on Sunday, leading to a wall collapse and waterlogging at several spots on the arterial LBS Marg.
A 6-ft-high wall that separated the alji Ladha Marg from a 20-ft deep pit on a construction site for a mall collapsed following heavy rain. The Brihanmumbai Municipal Corporation (BMC) had given the builder permission to build a two-layer basement for which the builder had had dug the pit.
“The soil supporting the wall must have dissolved due to heavy rain leading to the collapse of the wall and the footpath beneath it,” a senior civic officer said requesting anonymity because he is not authorised to speak to the media.
The civic body will on Monday check to see whether the work on the site was being done in line with the method the BMC had prescribed. “Our engineering staff will visit the site tomorrow to check whether the way the pit was being dug led to the collapse,” deputy municipal commissioner, Bharat Marathe, said.
More than four BEST bus routes had to be diverted because of waterlogging in Mulund.
The city witnessed a downpour for 30 minutes on Sunday afternoon because of low-pressure monsoon activity moving northward. The weather department does not foresee heavy rain in the next couple of days as the activity has moved past Maharashtra.
“Heavy rains are likely in north India. The city can expect some passing showers,” said RV Sharma, deputy director general, India Meteorological Department (Western region).
On Sunday, the suburbs recorded 17.03 mm rainfall but south Mumbai was comparably sunny with only 7.02 mm rainfall.
This monsoon has turned out to be one of the wettest for Mumbai in five years. The city has already recorded 3,226 mm of rain, 2,406 mm more than the average. The downpour made no difference to the temperature, which continued to be well above the 30-degree mark.
The evening was pleasant after a muggy morning with the showers leading to a drop in humidity by at least 10 per cent in the city and 22 per cent in the suburbs.
