(a) whether the Government is considering to facelift large dams in the country and if so, the details thereof, Statewise;
(b) whether there is any threat in terms of safety of dams as reported to the Government due to their overage and if so, the details thereof; and
(c) the major works which are going to be included in facelift of the dams?
THE MINISTER OF STATE FOR WATER RESOURCES, RIVER DEVELOPMENT AND GANGA REJUVENATION & PARLIAMENTARY AFFAIRS
(SHRI ARJUN RAM MEGHWAL)
(a) Yes, Madam. Government of India with financial assistance from World Bank started Dam Rehabilitation and Improvement Project (DRIP) in 2012 for rehabilitation of 223 dam projects, initially in 4 States (namely Kerala, Madhya Pradesh, Odisha and Tamil Nadu) and Central Water Commission (CWC). Later, Karnataka Water Resources Department, Damodar Valley Corporation (DVC) and Uttarakhand Jal Vidyut Nigam Limited (UJVNL) joined the project.
State-wise details of dams and fund allocated under DRIP are at Annexure-I.
(b) Safety of dams primarily rests with dam owners which are mostly State Governments, Central and State power generating PSUs. Dam owners generally carry out pre-monsoon and post-monsoon inspections of their dams to identify deficiencies or areas that need monitoring or immediate attention.
Union Government constituted National Committee on Dam Safety (NCDS) headed by Chairman, CWC and representatives from State Governments and PSUs. The objectives/mandates of NCDS are:
i) To oversee dam safety activities in various States and suggest improvements to bring these in line with the latest state-of-art consistently with Indian conditions.
Contd...P/2
//2//
ii) To act as a forum of exchange of views on techniques adopted for remedial measures to relieve distress.
iii) To monitor the follow-up action on the report on dam safety procedures.
iv) To recommend any other measures connected with dam safety.
38 meetings of NCDS have been conducted so far.
Under DRIP, safety conditions of about 225 dam projects have been comprehensively reviewed by the Dam Safety Review Panel (DSRP). During the comprehensive review by the DSRP, it was found that many dams have structural deficiencies and shortcomings in operation and monitoring facilities on account of ageing. Some dams do not meet the present design standards – both hydrologically and structurally. The list of dams reviewed by the DSRP under DRIP is at Annexure-II.
(c) The major works carried out for rehabilitation and improvement of dams under DRIP are:
i) Hydrological safety review to check the adequacy of the spillway for safely passage of revised design flood, through structural and non-structural measures;
ii) Treatment of leakage through masonry and concrete dams,
iii) Reduction of seepage through earth dams and their foundations
iv) Improving dam drainage;
v) Improving approach roads and access to all parts of dam;
vi) Rehabilitation and improvement of spillway, head regulator and draw-off gates and their operating mechanisms;
vii) Providing dam safety instrumentations, improving communication system between upstream and downstream control points;
viii) Preparation of Emergency and Disaster Management Plan;
ix) Preparation of operation and maintenance manuals etc.
