Govt order issued to build regulator across Kollidam

Trichy: The Tamil Nadu government has issued a GO (Ms Number 320) for constructing a new regulator across Kollidam river at Mukkombu Upper Anaicut to replace the damaged 182-year-old barrage. The new barrage would come up 75 metres away from the broken structure on the downstream of the riverbed.

Due to continuous heavy flow in the Cauvery during July and August, the piers along with shutters from six to 14 had collapsed and were washed away on August 22. Chief minister Edappadi K Palaniswami had announced after inspecting the spot on August 24 that a new regulator would be built replacing the old brick masonry structure. Subsequently, a temporary sand bund was constructed on the upstream of the river.

According to the order issued by the government dated December 6, the state government has accorded administrative sanction for the construction of the new regulator that will be coming up at an estimated cost of Rs 387.6 crore with Nabard assistance. The design was prepared in consultation with IIT-Madras after a team of professors visited the site and studied various aspects of construction. A comprehensive investigation was conducted at the site by the IIT experts before finalizing the design.

Going by the detailed project report (DPR), the estimation has been split into civil works and hydraulic operating system, for which a single tender has been floated. Given the importance and technicalities of the project, a global tender has been called for to enable the participation of competent companies with prior experience in construction of regulators and dams, officials said. The tender process would be completed by January-end, the officials added.
