DAM SAFETY IN CWC

Dam safety is not new in CWC. It started long back in early 80s with the establishment of Dam Safety Organisation to develop expertise and offer technical assistance in the field to dam owners. To begin with different dam safety documents were codified and some established and best practices of the world were emulated. Guidelines on dam safety were brought out to bring uniformity in this field. As a part of improving the existing conditions of the dams due to various reasons, following rehabilitation programmes have been taken up :

  1. Dam Safety assurance and Rehabilitation Project (DSARP)

    A World Bank assisted project, was implemented in four States – namely Madhya Pradesh, Orissa, Rajasthan and Tamil Nadu under guidance of CWC. The Project duration was from 1991 to 1999 at a cost of US$M86. The objectives of DSARP were to:

    1. Improve the safety of selected dams in the project states through remedial works
    2. Install basic dam safety-related facilities; and,
    3. Strengthen the institutional framework in CWC and project states responsible for assuring dam safety
    4.  

    5.  

    Under DSARP, total 33 dams (initially proposed 55 dams) in four states were taken up for rehabilitation&remedial measures were completed to bring them to the desired safety level. The rehabilitation works of the balance 22 dams were also completed subsequently by the four State Governments through their own fund. The DSARP has also helped in streamlining data collection at the dam level through standardizing pre- and post-monsoon reports. The project increased the awareness of dam safety issues, and improved capacity of implementing agencies to diagnose and prioritize problems.

  2. Dam Rehabilitation and Improvement Project (DRIP)

    The DSARP had provided a learning curve for further work in dam safety by creating awareness,concepts and psychological benefits of safe dams. Accordingly, efforts were made to extend the DSARP activities at wider scale and thus DSARP Phase-II was conceived in year 2000. However, due to substantial delays and undetermined interest of the dam owners, the project got delayed. Later, DSARP Phase-II emerged as Dam Rehabilitation and Improvement Project (DRIP).

    DRIP originally envisaged rehabilitation and improvement of some projects in four States – namely Kerala, Madhya Pradesh, Orissa, and Tamil Nadu – with funding assistance from the World Bank. Later on Karnataka, Uttarakhand (UJVNL) and Jharkhand (DVC) joined DRIP and total nos of dams to be covered under DRIP increased to 223. Hence, due to addition/deletion of dams during implementation by implementing agencies, presently 178 dam projects are being rehabilitated.The project started on 18th April, 2012 and will be implemented over a period of six-years.Original budget outlay for the scheme is Rs. 2100 Crore with World Bank assistance of US $ 279.5 M. Funding pattern is 80:20 (WB and State/ Central). The revised cost as of now is Rs. 3466 Crore with World Bank assistance of US $ 416.5 M. Objectives of DRIPare to:

    1. Improve the safety of selected dams in the project states through remedial works
    2. Install basic dam safety-related facilities; and,
    3. Strengthen the institutional framework in CWC and project states responsible for assuring dam safety
