Kolkata: The Kolkata Municipal Corporation plans to build drainage lines under 137 km of roads in parts of Sarsuna, Joka and along EM Bypass that lack underground drainage.
This work comes under a recently sanctioned Rs 2500 crore project. This project, named KMC Sustainability, Hygiene and Resilience (Sector) (KMC Sharp), will begin after Puja.
The large chunk of this Rs 2500 crore fund will be coming from an Asian Development Bank (ADB) loan. ADB will provide Rs 1,752 crore, the West Bengal government Rs 438 crore, and KMC another Rs 306.6 crore.
The project has to be completed by 2032 as per the loan agreement signed by the Centre, state, KMC and ADB.
The new drainage lines will be laid in Ward 108, covering areas like Anandapur, Chowbhaga and Panchannagram. In Ward 109, it will cover parts of Mukundapur.
Wards 126 and 127 will cover Sarsuna-Oxytown, Shakuntala Park-Sonamukhi and Wards 142 and 143 will cover parts of Joka. All these areas lack drainage lines.
More specifically, drainage lines will be built in Nayabad and Ajoynagar in Ward 109; Anandapur in Ward 108; Julpia and Kabardanga in Wards 142 and 143; and Sonamukhi Main Road, Kastodanga Road and Jadav Ghosh Road in Wards 126 and 127.
Earlier, sewage used to be drained into canals through natural slopes and the flow of drains. Such drainage without treating the sewage is prohibited now.
New drainage lines, along with sewage treatment plants, will be built under the project.
In several areas, there are underground drainage lines, but these are either inadequate or used to drain sewage into canals without any treatment.
In some other stretches, there are no drainage lines at all. There is a new underground network that has to be built.
Of the 137 km, there would be 71 km of trunk sewer lines under the main roads of neighbourhoods. The remaining would be lateral sewer lines under branch roads.
