Water is a state subject and water resources projects are planned, executed and maintained by respective State Governments from their own resources and as per their requirements and priorities.
The role of the Central Government is limited to supplement the efforts of the State Governments by providing technical guidance and central assistance through its various schemes, if specifically sought by the State Government.
Central Water Commission (CWC) compiles and maintains nation-wide register of Large Dams i.e. National Register of Large Dams (NRLD), as per information provided by dam owners.
Under National Register of Large Dams (NRLD), CWC does not maintain the data of cost of construction of dams.
Responsibility for safety, conservation and protection of dams primarily lies with Dam Owners who are State Govts, Central and State PSUs and some private players.
National Committee on Dam Safety (NCDS) is an advisory body which suggests ways to bring dam safety activities in line with the latest advancements in the field, suitably modified for Indian conditions and acts as a forum for exchange of views on techniques adopted for remedial measures to relieve distress in old dams.
In the ongoing Dam Rehabilitation and Improvement Project (DRIP), there is a need-based provision for partner agencies to restore the lost capacity of few selected dams.
Under DRIP, Central Water Commission (CWC) has published “Handbook for Assessing and Managing Reservoir Sedimentation” and recommends dam owners to follow this handbook.
India ranks third globally with 5334 large dams in operation and about 411 are under construction. In addition, there are several thousand smaller dams.
The World Bank assisted Dam Rehabilitation and Improvement Project (DRIP) project originally envisaged the rehabilitation and improvement of 223 dam projects in four states namely, Kerala, Madhya Pradesh, Odisha, and Tamil Nadu. Later Karnataka, Uttarakhand (UJVNL) and Damodar Valley Corporation (DVC) joined the DRIP.
Cabinet Committee on Economic Affairs (CCEA) has approved the next Phase of DRIP i.e. DRIP Phase II and Phase III in October 2020.
The Scheme envisages comprehensive rehabilitation of 736 dams located in 19 States and 3 Central Agencies and entails financial assistance from the World Bank (WB) and the Asian Infrastructure Investment Bank (AIIB).
It is a State Sector Scheme with Central component, with duration of 10 years, to be implemented in two Phases i.e. Phase-II and Phase-III, each of six years duration with an overlap of two years.
