Repair and restoration of one of the four blocks of the 109-year-old Tallah water tank have been completed and work to restore another compartment will start from Thursday.
Kolkata Municipal Corporation mayor Firhad Hakim inspected the progress of work on Wednesday. “The tank had not been repaired for the past 100 years. The present KMC board had decided to take on complete repair and restoration work of the reservoir. The work was initially not sanctioned under the Centre’s JNNURM and AMRUT schemes, but later on, 30% of the total project cost was sanctioned under AMRUT and the rest was to be funded by the state. The Bridge & Roof Company Ltd and KMC engineers jointly took up the work,” Hakim said, adding that the total project cost is Rs 80 crore, of which Rs 42 crore has been spent so far.
Accompanied by the engineers, the mayor on Wednesday entered the compartment that has been repaired to inspect how the work has been carried out. “JU engineers have been providing technical supervision and KMC engineers have been coming up with the structural design for the project,” the mayor said.
Hakim added that the structure had started to rust and was in a dangerous condition. “One of the blocks has now been completed. We are taking up one block after another to ensure there is no interruption of water supply,” the mayor said.
The engineers said water storage in the repaired northwest block will start soon and supply will resume.
Engineers said the restoration covers a number of areas, including strengthening of the 110ft-long steel structure, replacing the concrete slabs on the roof with steel slabs and removing corrosion from the steel structure and arresting the leaks. “The concrete slabs on the roof are being replaced with steel to reduce weight on top,” said an engineer, adding that the strength of the pillars is also being increased.
