CM launches new Kollidam regulator works

The special feature of the upcoming regulator is that it will have hydraulic hoisting mechanism for its shutters while, pile foundation system would be made to ensure its strength. The PWD officials said that this would be the first structure in the whole of Tamil Nadu with hydraulic hoisting mechanism.

“In the old structure, the shutters were raised using motors. With the hydraulic technology, we can now raise the shutters to the point very accurately,” the PWD officials said. The regulator has two arms. South arm has 45 shutters and the north has 10 shutters. Both these arms are now being built a new under this project.

The new regulator construction works are scheduled to be completed in 24 months.  After completion of the project, the irrigation for the districts like Thanjavur, Tiruvarur, Nagapattinam and Pudukkottai would be ensured and the land in an area of 12 lakh acres would be benefitted, the officials said. The repair works at the remaining portion of the collapsed regulator would include fixing sheet piles, cutoff wall and coffer dam.
