Tiruchy: The construction of a new barrage across the river Kollidam at Mukkombu near Tiruchy at an estimated cost of Rs 387.60 crore is going on in full swing and civil works are expected to be completed by March 2021.
It might be recalled the vents from 6 to 14 located on the southern side of the very old barrage across river Kollidam had collapsed due to floods during the Southwest monsoon period on August 22 last year. Following this, Tamil Nadu Chief Minister Mr. Edappadi K Palaniswami visited the site and ordered the construction of new barrage.
The new barrage will have 45 vents on South Kollidam riverside and ten vents on the northern side, with 484 piers. So far, 70-m long structure has been completed.
The new barrage is coming up 75-m away from the collapsed structure.
The Tamil Nadu Government had also sanctioned Rs 38.85 crore for strengthening the old barrage until the new barrage is put to use, to ensure regular supply of water for delta irrigation and to safely let out any sudden floodwaters. The construction of new barrage as well as the strengthening of the old barrage is going on simultaneously.
Under the strengthening of the old barrage project, construction of a cofferdam on the western side of the damaged barrage, a full-length of additional diaphragm wall besides concrete flooring is going on. These works are expected to be completed by August 20, according to PWD sources.
The sources said the ongoing construction of the new barrage will not be affected if there is a routine flow of water, but in the event of any major flood, the work may be affected and consequently completion slightly delayed.
