## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI

( SHRI BISHWESWAR TUDU )

(a)  &  (b) As  per  the  National  Register  of  Large  Dams  (2019)  compiled  by  the  Central  Water Commission, there are 5334 completed large dams in the country. The State/UT-wise list of these large dams is attached as Annexure .

Out of these 5334 large dams, there are 234 numbers of large dams, which are more than 100 years old (i.e. constructed in or before 1922). The State/UT-wise list of these dams is attached as Annexure .

(c) & (d) Dam owners, which are mostly the State Governments and Central/State Undertaking, carry out  themselves  the  safety  audit  in  terms  of  periodical  pre-monsoon  and  post-monsoon  inspection  of their dams to identify deficiencies or areas that need monitoring or immediate attention.  Some States have  also  constituted  the  Dam  Safety  Review  Panel  consisting  of  various  domain  experts  for comprehensive inspection of the dams to assess the structural and operational safety. However, the life span  of  a  dam  is  normally  till  such  time  it  performs  its  intended  functions  without  jeopardizing  the safety of people living in its vicinity.

Further,  Union  Government  has  enacted  the  Dam  Safety  Act,  2021  for  proper  surveillance, inspection,  operation  and  maintenance  of  the  specified  dams  for  prevention  of  dam  failure  related disasters and to provide for institutional mechanism to ensure their safe functioning and related matters.

The Act provides for Comprehensive Dam Safety Evaluation of each of the specified dam through an  independent  panel  of  experts  constituted  for  the  purpose  for  determining  the  conditions  of  the specified dam and for general assessment of the dam in respect of hydrologic, hydraulic, seismic and operational safety considerations.

In order to improve the safety and operational performance of select existing dams in the country, Government of India is implementing the Dam Rehabilitation and Improvement Project (DRIP) with external funding.  Under the World  Bank funded DRIP Phase-I programme, which was implemented during April 2012 to March 2021, 223 existing dams located in 7 States have been comprehensively audited and  rehabilitated at a cost of Rs. 2,567 crore. After completion of DRIP Phase- I programme, Government of India has taken up DRIP Phase-II & III. The scheme envisages rehabilitation and safety improvement of 736 dams located in 19 States, with a budget outlay of Rs 10,211 crore. The scheme is of 10 years duration.
