## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI

## ( SHRI BISHWESWAR TUDU )

(a)  to  (c) As  per  the  National  Register  of  Large  Dams  (2019)  compiled  by  the  Central  Water Commission (CWC) based on the information provided by the dam owners, India has 5,334 completed and functional large dams. Out of these, there are 234 functional large dams in the country which are more  than  100  years  old.  Further,  there  are  1,034  operational  large  dams  in  the  country  having  age between 50 to 100 years. State-wise number of these dams is enclosed as Annexure-l. However, age of the dam is not the only factor to assess a dam's condition. These superstructures have a valid lifespan as long as they are technically safe and operational.

Responsibility for ensuring safety of dams, including their operation and maintenance, rests primarily with  the  dam  owners  which  are  mostly  the  State  Governments  and  Central/State  Public  Sector  Units. Details  regarding  dam's  condition,  safety  assessment,  maintenance,  repair  and  renovation  are  available with the concerned dam owners.

Union  Government  has  enacted  the  Dam  Safety  Act  2021  to  provide  for  surveillance,  inspection, operation and maintenance of all the specified dams of the country for prevention of dam failure related disasters and to provide for institutional mechanism to ensure their safe functioning. Under the Act, dam owners are required to carry out the pre-monsoon and post-monsoon inspections of their dams. On the basis  of  the  examination  of  periodic  inspection  report  of  the  dams  and  its  vulnerability  on  all  safety aspects,  they  are  categorized  as  Categories  I,  II  or  III  (Category  I  being  the  severe  most  category  and accordingly).  Category-I  indicates  deficiencies  which  may  lead  to  failure  while  Category-II  indicates deficiencies requiring prompt remedial measures. Consequently, the remedial measures are carried out by the dam owners in a time bound manner.

## SAFETY OF OLD DAMS

As per the pre-monsoon inspection of the specified dams carried out by the dam authorities during the  financial  year  2023-24  till  11.07.2023,  4  dams  have  been  found  in  Category  I,  and  169  dams  in Category  II  (list  enclosed  as Annexure-II ).  The  State  Dam  Safety  Organization  and  the  Project Authorities have been requested to take necessary steps to ensure continued safety of these dams.

(d) In  order to  improve the safety  and operational performances of some of the selected dams of 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.

Under this scheme, repair of cracks have been carried out in several dams. Some of the prominent dams are Kankerdheda (Madhya Pradesh), Hirakud (Odisha), Gatana (Tamil Nadu), Pazhassi Irrigation Project  (Kerala),  Idukki  (Kerala),  Upper  Mullamari  Dam  (Karnataka),  Konar  and  Maithon  dams (Jharkhand) etc.

After completion of DRIP Phase- I scheme, Government of India has taken up DRIP, Phase-II & III envisaging rehabilitation of 736 dams located in 19 States with a budget outlay of Rs 10,211 crore. The scheme is of 10 years duration. DRIP Phase-II has become operational from 12th October 2021, and is being co-financed by the World Bank and the Asian Infrastructure and Investment Bank.

Further,  as  per  the  provisions  of  the  Dam  Safety  Act,  2021   dam  owners  are  required  to  earmark sufficient and specific funds for maintenance and repairs of the specified dam.
