Navi Mumbai silt removal work in the Koparkhairane MIDC area has cost the Navi Mumbai Municipal Corporation approximately Rs 1.5 crore after illegally dumped material entered four nearby factories during the monsoon, according to a report by Loksatta – Navi Mumbai.
The expenditure was incurred through the civic body’s disaster management department after silt and debris dumped in the stone quarry area of Koparkhairane MIDC were washed into the adjoining industrial zone following rainfall. The cleanup proposal was placed before the municipal corporation’s standing committee and approved during its meeting on Wednesday.
Former Navi Mumbai mayor Jaywant Sutar alleged during the meeting that the dumped material was silt removed from Mumbai’s Mithi River. The report attributes that claim to Sutar; the material’s origin was not independently established in the information available for this report.
The silt was reportedly brought to the quarry area at the beginning of the monsoon in June. After rainwater accumulated at the site, the material moved towards the neighbouring industrial area. Four factories were affected after the silt entered their premises, resulting in what the report described as significant damage.
The municipal corporation’s disaster management department then undertook urgent removal work because of the seriousness of the situation. The operation was treated as an emergency response, with the resulting cost estimated at Rs 1.5 crore. The standing committee’s approval regularises the expenditure incurred for the cleanup.
The discussion also focused on who should bear the financial burden. Members questioned whether the municipal corporation would recover the cost from those responsible for illegally dumping the silt. The issue places the responsibility for enforcement and cost recovery alongside the immediate need to protect industrial premises from flooding and debris movement.
The episode highlights the operational risks created when excavated silt or other waste is deposited at sites that are vulnerable to rainwater accumulation. In this case, the dumped material moved from the quarry area into an adjoining industrial zone, requiring the civic authority to deploy emergency resources after private premises were affected.
The report did not specify the identities of the parties accused of dumping the material, the amount recovered through enforcement action, or whether a final determination has been made about the silt’s source. The immediate administrative milestone is the standing committee’s approval of the emergency expenditure and the question of whether the amount will be recovered from those responsible.
