Kolkata: Drones to find stagnant water on Salt Lake roofs

KOLKATA: Bidhannagar Municipal Corporation has started using drones to check if water is accumulating on terraces or around buildings in Salt Lake as part of dengue-prevention steps taken by the authorities.
“We have started using drones with support from Bidhannagar police to detect if dengue larvae are breeding in water on roof tops. We started with Ward 29 and residents have been urged to see there is no water accumulation on their terraces,” said mayor Krishna Chakraborty.
The authorities have been discussing with the State Urban Development Agency how to prevent water accumulation on terraces of locked buildings. Civic teams will also make inspections across all 41 wards.
“We will intensify spraying larvicide as well,” said an official.
