PERFORMANCE BUDGET 2004-2005 PART - C WATER RESOURCES ORGANISATION I. IMPORTANT PROJECTS During 2004-2005, the following important irrigation schemes were under execution. Modernising of Thanjavur Channels. In the Cauvery Delta, irrigation is provided to an extent of about 9.59 lakh acres (including 27,000 acres in Pondicherry State). This is an age-old delta irrigation system in the State. The head of the delta is the Grand Anicut, where the main Cauvery River branches as Cauvery and Vennar rivers. This again divides into 36 smaller branches with a total length of 1,607 km. There are 29,881 channels with a total length of 23,960 km. The modernization of the whole system has become necessary to secure better water management and optimum utilization of water. Main features of modernisation 1. Improvement to head works. 2. Improvements to transmission system i.e. raising and strengthening the river banks, putting up regulators and protection works across the rivers for control as well as for command purpose. 3. Raising the channels to standards and provision of structures. 4. Improving the existing drainage for submersion relief. 5. Lining of channels up to 40 hectares (100 Acres) limit. The works, viz. items 2 to 4 were taken up in the first phase of the project and completed in 1976. In the second phase, lining of channels up to 40 hectares (100 acres) limit has been taken up from 1977-78 onwards under the head of “Modernization of Cauvery Delta Channels”. So far, lining works have been completed for a length of 854 km, out of the total length of 1,223 km. under the 65 ‘A’ Class Channels and improving the drainage works. 2 A comprehensive proposal for rehabilitation of Cauvery delta irrigation system has been prepared for Rs.460 crore and sent to Government of India for consideration and to be taken up with the financial aid from World Bank. The Government in March 1997 have accorded sanction for carrying out improvements to four Irrigation channels, viz. (1) Palavanthankattalai Channel, (2) Perumandi Channel, (3) Ullur Channel and (4) Thepperumanallur Channel at an estimated cost of Rs.2.35 Crore. These works have been completed. The Government in January 1999 have accorded sanction for Rs.1.91 crore for providing bed lining and raising of retaining wall of the above four irrigation channels in Kumbakonam town limit. These works have been completed in June 2004. By implementing this scheme 229 acre of land has been stabilized. Parambikulam - Aliyar project Ayacut extension work has been completed for an extent of 46,540 hectares in the first stage, 10,120 hectares in the second stage and 14,170 hectares in the third stage in Dharapuram and Kangeyam Taluks of Erode District.
