DAMS LOCATED IN FOREST AREAS 3 • Some Projects located in Reserved Forest and Sanctuaries Areas, a challenge to rehabilitate • Contractors not willing to bid due to complexities in taking pertinent permits • Delays in whole rehabilitation process
POOR CAPACITY BUILDING OF FEW AGENCIES • Few Agencies lacked requisite exposure of contract management as well as other technical activities • Lack of synergy among Agency’s wings 4 • Resulted in more legal implications & cost variations Future Activities – DRIP 2

• 18 States + 2 Central Agencies + 687 dams • 10 years, each phase of 6 years with 2 years overlapping • US$ 1.5 Billion • Four Components
World Bank US$ 1000 M
States US$ 402 M
Central US$ 57 M Project Cost Lessons Learned and Recommendations
52 Lessons Learned and Recommendations
1. JWA’s Experience and knowledge through Japan Exposure Visits • JWA’s experience and knowledge was widely appreciated by India counterparts. • Each visit had specific themes; e.g. sedimentation management, flood forecasting and management system for dam operations – this gave good understanding of the participants on various topics of dam safety 2. Technical Assistance of JWA in the preparation of Manual for Post-seismic activities • Preparation of Manuals as technical assistance activities by JWA was found very useful and practical for the field engineers in the dam safety offices in India. • Mock activities based on the Manual prepared – participated by not only UJVLN engineers but many DRIP engineers from 7 states were very helpful and provided practical technical assistance in post-seismic activities. 3. World Bank’s Water Global Practice has other dam safety programs for JWA’s collaboration • In addition to DRIP project in India, there are other dam safety programs in Sri Lanka, Vietnam and Indonesia presently being financed by the World Bank. • These programs would also require technical assistance and supports from JWA and MLIT counterparts from Japan.
