## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI

(SHRI BISHWESWAR TUDU)

(a) & (b) Responsibility for safety of dams, including its operation and maintenance, rests primarily with dam owners, which  are  mostly  the  State  Governments  and  Central/State  Public  Sector  Units.  Details regarding dam safety assessment, maintenance, repair and renovations are available with the concerned dam owners.  Further, generally dam owners themselves carry out the safety audit (in terms of periodical pre-monsoon and post-monsoon inspection) of their dams. Some States have also constituted the Dam Safety Review Panel for comprehensive inspection of their dams.

Under the World Bank funded Dam Rehabilitation and Improvement Project (DRIP) Phase-I programme implemented during April 2012 to March 2021, 223 existing large dams located in 7 States have been comprehensively audited and rehabilitated at a cost of Rs. 2,567 crore. Further, as part of preparatory activities  for  DRIP  Phase-II  &  III,  comprehensive  safety  inspections  of  351  large  dams  have  been conducted by the Dam Safety Review Panels. State-wise details in this regard are placed at Annexure-I. In addition, as per National Register of Large Dams 2019 compiled by the Central Water Commission under this Ministry, there are 227 numbers of operational large dams in the country which are more than 100 years old (i.e., constructed in or before 1921).  State-wise list of these 100 years old dams is placed at Annexure-II .

(c)  &  (d) Water  being  a  State  subject,  construction,  operation  and  maintenance  of  water  resources projects including check dams is primarily States' responsibility. The information related to number of check dams, their functionality and their upkeep etc. lies with the respective State Governments.
