In order to prevent garbage from entering the sea, the BMC has reintroduced its trash boom project. Trash booms are floating filters that are placed in nullahs and rivers to prevent garbage from entering into the sea. It also prevents blocking of the outlet, which leads to water logging.
The civic body had installed trash booms three years ago. This was implemented at a cost of Rs 1.17 crore. However, it did not yield much result. Now, the BMC is all set to get nine new trash booms at a cost of Rs 48 crore.
The new trash booms will also come with a cleaning mechanism. The officials from the storm water drain department said that the earlier experiment failed because the booms did not have a cleaning system in place.
After repeated warnings from the National Green Tribunal to stop waste from entering into the sea, the civic body had installed the filters at the mouths of various nullahs and rivers like Irla, Mogra, P&T, SNDT nullahs and Dahisar, Poisar, Oshiwara and Mithi rivers in 2019.
According to the new proposal, the civic body will be installing nine trash booms at various locations. The cost is much higher than the earlier project implemented in 2019, but the storm water drain department officials justified the decision and said that they would come up with installations, barges, collection and transport system of the waste and maintenance for three years.
The actual cost of the booms, barges and installation has been pegged at Rs 13.5 crore. The new trash booms will be installed at Main Avenue, Gazdar Bandh nullah, Mogra nullahs and Oshiwara, Poisar, Dahisar, Vakola rivers and at two places along the Mithi river near Maharashtra Nature park and near Bandra Kurla complex bridge. The BMC has shortlisted Virgo Specialties Private Limited that has a tie-up with a Denmark-based company. They will supply, install, operate and even carry out the maintenance of these trash booms.
“The company has already installed such booms in Yamuna river in Delhi. They will also provide barges that will help collect trash across the nullahs and river,” said a civic official.
