A day after the rain on Tuesday, the Coimbatore Corporation had its task cut out – it had to desilt drains, remove waste in sewerage system, close pits and flatten roads for smooth movement of vehicles and also clean underpasses.
It started dewatering the underpasses at Lanka Corner, Kaleeswara Mills and Kikani School and also those beneath the Avinashi Road and North Coimbatore flyovers on Tuesday night, soon after the rain stopped. The operation, however, continued well into Wednesday afternoon as there was too much water to be drained out at Avinashi Road and North Coimbatore and too little power to run the motors.
A senior Corporation official told The Hindu that alternate hour power cut ensured that the 50 hp motor at the Avinashi Road underpass could not be used to the maximum extent. It was forced to rely more on the two motors – 50 hp and 20 hp – that were powered by diesel to drain out the water.
He said that had the Corporation had uninterrupted power to run the motor, it could have thrown open the underpasses by Wednesday morning.
In the East Zone, following complaints of inundation and choked drains, Mayor S.M. Velusamy led a team of officials to Trichy Road, Nanjundapuram, G.V. Residency, Neelikonampalayam and other areas. Corporation sources said that at Seruppadi Palam, near Alvernia school, he ordered the Corporation officials to desilt the Sanganoor Pallam and remove the wastes that obstructed the flow of rain water.
The officials said that waste from households and industries upstream got into the Sanganoor Pallam and that choked the flow near the Palam. By evening the civic body had used an earthmover to remove the waste and deepen the Pallam.
On Thursday the officials will take up work to strengthen the revetments, said the Ward Councillor S. Thamarai Selvi.
In Neelikonampalayam and other areas in Ward 62, the Mayor asked the Corporation officials to demolish and construct afresh two causeways – in Chinna Gurusamy Layout and Iyer Layout – to ensure clear flow of rain water. The Ward Councillor Singai S. Balan said that the Mayor had instructed the officials to rise the height of the causeways by over a foot.
In G.V. Residency and Nanjundapuram, Mr. Velusamy asked officials to deepen and widen the drain so as to ensure smooth flow of rain water.
In Nanjundapuram he directed the officials to take the water to the nearby natural drain in the South to ensure that the road was not inundated.
He also asked for earth to be filled at places where the underground drainage work was completed.
The officials said that by Thursday they would complete the works the Mayor has asked them to execute.
