- Routine Periodic Inspection
- By trained and experienced engineers from DSO
- At least twice a year : pre monsoon and post monsoon
- Examination of general health of the dam and appurtenant works
- Preparedness of dam and hydro mechanical structures for handling expected floods
- Comprehensive Dam Safety Evaluation
- Once in a 10 year
- More comprehensive examination
- Multi-disciplinary team for holistic view
- May order additional field and laboratory investigations as well as numerical simulations
- CDSO has prepared a number of guidelines on dam safety and circulated these to the State Governments and other organisations for implementation.
- CDSO (in 1990) compiled an National Register of Large Dams which is being updated continuously.
- CDSO is regularly imparting trainings to the engineers of CWC as well as State Governments to enhance their knowledge and skills in the field of Dam Safety.
- Assistance by CDSO is rendered only on specific request from State Governments. Apparently, it is not practical for such a dam safety service at the Centre to cater to the needs of all the dams in the country.
