Two years ago, the municipal body was warned about the dilapidated condition of the 90-year-old storm water drain that collapsed on Wednesday, causing a portion of Dr Narayan Hardikar Road in Worli, to cave in. The warning was ignored.
A builder working on an SRA project across the spot that caved in was asked by the civic corporation to concretise the portion of the drain that runs across his construction site.
“It was a condition put by the civic body while sanctioning the project,” said an official.
A civic official said the total length of the drain is 560 metres of which, 400 metres falls in the builder’s premises. While concretising the drain in his area, the developer observed the remaining part of the drain had also decayed.
He then wrote to the civic ward office informing them about the condition of the 160 metres of the drain in 2008.
“The builder pointed out that the drain was in a bad shape and needs urgent repairs and that he could do it as he had already appointed an agency,” said an official requesting anonymity.
“But the ward office said the civic body will carry out the concretisation of the drain on their own as it was not the jurisdiction of the builder,” he added.
“Over the years, the problem was neglected. After two years of corrosion, the drain collapsed on Wednesday,” added BJP corporator Ashish Shelar.
Chief Engineer of Storm Water Drains Department, Chandrakant Watwe, said he will have to check the records and verify whether such a warning was given to the department.
A day later, work on the site had begun. Debris from the hole was excavated and the process of laying the temporary pipeline will start on Friday.
