Collector visits the completed revetment wall and ramp at Punavasal village
Flood prevention works taken up along the Kollidam river in Thanjavur district by the Public Works Department (PWD) are nearing completion. The works were started in October 2010. Out of the total works taken up at a cost of Rs. 106.22 crore, works to the tune of Rs. 93.34 crore have been finished so far. The rest will be completed before the end of March.
K.Baskaran, Collector, inspected the works along with V.Ravichandran, Executive Engineer, PWD - Cauvery Division, on Thursday. The Collector saw the completed revetment wall and ramp along the right bank of the Kollidam river at Punavasal village, groins at Vaidyanathanpettai, and drainage regulator at Vadukacheri village in Tiruvaiyaaru taluk. He also saw the road laid on the bank of the Kollidam. He said in Thanjavur district flood prevention works along the Kollidam were taken up at Thiruvaiyaru, Papanasam, and Kumbakonam areas.
Fifty five groin works were undertaken (groins stop the overflow of water and channel them in the proper course in the rivers ) of which 54 have been completed, and work is going on at one groin. Construction of 109 ramps and rivetment wall to a distance of 5,256 meters were taken up. Tar road has been laid to a distance of 91.62 km. "Ninety per cent of the works have been completed and the rest will be completed before March-end," the Collector said.
Heavy floods in 2005, when 4.50 lakh cusecs of water were carried by the Kollidam necessitated the flood prevention works. During 2005, breaches occurred along the banks of the Kollidam at many places. Crop damage, loss of human lives, and cattle loss were reported in the district.
With a view to find a permanent solution to this problem, PWD, water resource division, Tiruchi, submitted a proposal to the tune of Rs. 375.90 crore to the Central Water Commission. The Central government approved the proposal, and allotted Rs.375.90 crore for taking up flood prevention works along the Kollidam in Thanjavur, Nagapattinam, and Cuddalore district. Works were taken up with 75 per cent contribution from the Centre, and 25 per cent from the State government.
Accordingly, works were taken up to raise the right bank of the Kollidam from the Grand Anicut to Vettamangalam to a height of 1.50 meters. The idea is to make the river carry 4.50 lakh cusecs of water without any breach or danger to surrounding areas.
"When the works are completed by March-end, there may not be flood danger to Papanasam, Tiruvaiyaaru, Kumbakonam, and Thiruvidaimaruthur areas of Thanjavur district from the Kollidam.
These are all long-term works, and they will go a long way in preventing floods," said Mr. Baskaran.
