Residents of the City, who get jittery over the possibility of floods whenever the Cauvery is on spate during the monsoon seasons, can breathe easy now as the Public Works Department has completed a substantial portion of work on building permanent protective structures along the vulnerable stretches of the Cauvery and Coleroon rivers in the district under the Rs.253-crore flood control project.
Strengthening the bunds of the Cauvery and Coleroon Rivers in Tiruchi, Karur and Ariyalur districts account for a major segment of the project. Emphasis has been on fortifying the vulnerable stretches, wherever breaches occurred and places where the river bunds threatened to give away during the 2005 November floods. The works have been taken up on different stretches from Jeddarpalayam on the Cauvery River and from Mukkombu on the Coleroon River.
Protective structures, called ‘tow walls,’ were being built at places such as Vengur, Kookur, Kiliyanallur and Kiliyur were breaches occurred in 2005. Tow walls have also been built at Melur, where the Cauvery River bund very nearly gave away that year threatening to submerge Srirangam.
At Vengur, where a major breach occurred in 2005 flooding large areas along the Tiruchi-Thanjavur Highway, tow walls with concrete revetments were being built for over 100 metres. This apart, the right bank of the river stretch from the Tiruchi-Chennai By-pass Road, to Sarkarpalayam/Grand Anicut was also being strengthened.
About 60 per cent of the work on the Rs.253.71-crore flood control project has been completed and several vulnerable stretches of the Cauvery and Coleroon Rivers in Tiruchi district have been reinforced, according to Collector T.Soundiah.
While tow walls were being built in some of the stretches, retaining walls have been built in several other stretches, said K.K.Palanisamy, Superintending Engineer, PWD, Middle Cauvery Basin. This apart, the height and width of the bunds of the rivers have been strengthened.
