Health status report
Health Status Report of Tamilnadu WRD Dams for the Monsoon – I Period (10th June 2012 to 15th August 2012) Madurai Region
GENERAL
1. Health status report is prepared based on the deficiencies pointed out by the inspecting officer in the monsoon report. The deficiencies are noted in descending order priority wise. They may be attended and rectified accordingly.
2. Field officers were requested to report the action taken on the review remarks communicated to them on the previous monsoon reports and enclose the same while sending the subsequent report. The instructions given were carried out in respect of few dams only. So the action taken report for the previous monsoon reports must be enclosed by the field officers in future while sending the subsequent monsoon reports.
3. As per the ICOLD,
The height of dam = Top of dam – Deepest foundation level.
Accordingly find out the deepest foundation level of the masonry dam from the as built drawings and the height of the dam has to be reckoned from the deepest foundation level. 4. All the as built drawings of the components of the dam have to be kept ready for inspection and also for references. I. Dams with Major Deficiency
1) Manimuthar Dam in Tirunelveli District.:
1. Actions shall be taken to arrest the abnormal seepage reported in shaft no.33 and 35 of masonry dam near river sluice vents 2 & 4 by grouting the body wall of the dam besides upstream face treatment. 2. Grouting shall be carried out to control the dampness in masonry dam in block no.6 & 7 (LS 5879 ft to 6059 ft.) 3. Disturbed rip rap in upstream slope of the earth dam is to be removed and repacked. 4. Bitumen access road is to be improved in the left out portions. 5. Worn out rubber seal of river sluice shutter is to be renewed. 6. Instrumentations are to be provided. 7. Collapsed chutes should be reconstructed. 8. ‘V’ Notches are to be repaired and measurements should be taken regularly. 9. Exact deficiency in the earth dam slope should be reported in the relevant column of the bund. 10. Communication facilities should be improved. 11. Worn out rubber seal of outlet gate is to be renewed. 12. Emergency action plan should be reviewed every year. 13. Weather station instruments are to be repaired and should be brought to working condition.
