Currently, India ranks third globally with 5264 large dams in operation and about 437 are under construction. These dams are important for ensuring the water security of the Country, and these also constitute a major responsibility in terms of asset management and safety. In April 2012, the Central Water Commission (CWC) under Ministry of Water Resources, River Development & Ganga Rejuvenation with help from the World Bank, embarked upon the six-year Dam Rehabilitation and Improvement Project (DRIP) at an estimated cost of Rs. 2100 crore. The scheme originally envisaged the rehabilitation and improvement of about 223 dams within four states namely, Kerala, Madhya Pradesh, Odisha, and Tamil Nadu and later Karnataka, Uttarakhand (UNVNL) and Jharkhand (DVC) joined DRIP and total number of dams covered under DRIP increased to 250; due to the addition/deletion of dams during implementation by partner agencies, currently 223 dams are being rehabilitated . The scheme will also promote new technologies and improve Institutional capacities for dam safety evaluation and implementation at the Central and State levels and in some identified premier academic and research institutes of the Country. The Central Dam Safety Organisation of Central Water Commission, aid by Engineering and Management Consultant, is coordinating and supervising the Project implementation. The DRIP has been given an additional extension of two years with revamped official closure now June 2020.
- To enhance the safety and operational performance of selected existing dams and associated appurtenances in a sustainable manner, and
- To strengthen the dam security institutional setup of participating States / Implementing Agencies.
The aim of DRIP is to be achieved through investments in rehabilitation and improvement of dams, improved management of dam operations, regular maintenance and accompanying institutional strengthening and reforms. DRIP would outcome in restoring the full operational capacity of project dams for effective utilization of stored water and improved performance on a long-term basis with reduced risk of failure/safety incidents.
The in-house holding capacity of selected eight Academic institutes will also be improved under DRIP; these institutes, in turn, provide training and expertise (consultancy) to DRIP Implementing Agencies. Rehabilitation and Improvement of Dams and Associated Appurtenances: Rehabilitation and Improvement of Dams and Associated Appurtenances, focusing on structural and non-structural measures at 223 project dams, maximum of which are more than 25 years old.
Dam Safety Institutional Strengthening
Dam Safety Institutional Strengthening, focusing on regulatory and technical frameworks for dam safety assurance. The tasks to be carried out will include, but not be limited to, targeted training nationally (especially at the National Water Academy in Pune) and internationally to Dam Safety Organizations at Central (CDSO) and State (SDSO) level to become effective organizations that can take the lead in ensuring that dams remain safe from a structural and operational point of view; in-country and external training of staff of WRDs and SEBs to assist with the development of appropriate skills and modern tools to adequately operate and maintain dams; attendance at dam safety courses; study tours, and linking with foreign country agencies that have advanced dam safety programs such as the United States and Switzerland; operation of independent dam safety review panels, comprising experts in relevant disciplines; development of capacity to carry out reservoir sedimentation studies; development of Management Information Systems (MIS) and other programs to capture and analyze data for long-term planning and guiding of dam operations; support to the further development within CWC of the Dam Health and Rehabilitation Monitoring Application (DHARMA) program that will allow a systematic presentation and interpretation of data for effective monitoring of the health of dams; support to the revision of existing guidelines on dam safety and preparation of new guidelines, as needed; training in hazard and vulnerability assessment and dam-break analysis; and training to a select number of academic and research institutions for enhancing their capacities in guiding the dam safety activities.
