A 19-year-old labourer suffocated to death after a heap of silt fell on him when he was cleaning the storm water drains at Pant Nagar in Ghatkopar.
“The supervisor, Phulsinh Rajput, and the contractor, Dinesh Yosh were arrested for negligence on Saturday,” said MS Suryavanshi, senior inspector of the Pant Nagar police station.
Civic officials said the incident took place on Friday evening when Chandwa Nagappa (19) and 10 other labourers were cleaning and widening the storm water drains as part of the municipal corporation’s pre-monsoon work.
Nagappa was inside the storm water drain when the silt piled on the mouth of the drain fell on him. The other labourers rushed to rescue him, but within 10 minutes he died of asphyxiation. The sewage water that also flows through the drain made it difficult for the labourers to rescue him.
Nagappa was rushed to Rajawadi Hospital at Ghatkopar but the doctors declared him dead before admission.
Every year, before the onset of monsoon, the municipal body cleans storm water drains across the city to increase their water holding capacity to mitigate the effect of waterlogging.
The city has a 1,987-km storm water drain network.
The silt removed from the drains is kept at the site for more than 48 hours so that it can dry. It is then transported to the dumping ground.
