"Of the 601 ongoing projects, 225 projects were under execution for more than 15 years, of which, 77 projects were under execution for more than 30 years. In the test-checked projects, 16 projects were under execution for more than 30 years.
"Further, of the 601 ongoing projects, there was a cost overrun of Rs 47,427.10 crore in 363 ongoing projects, while in 83 out of 87 test-checked projects, the cost overrun was to the extent of Rs 12,807.64 crore," the CAG report said.
CAG said the audit is an attempt to review not only the individual irrigation projects selected in the sample, but also discuss in sufficient detail the project-level planning, tendering and contract management and project implementation.
In 37 out of 87 test-checked projects on which an expenditure of Rs 9,078.58 crore had been incurred, complete land (forest and civil) was not acquired before commencement of work thereby depriving the users of the benefits of the projects, the report said.
Estimates for irrigation projects were prepared without proper survey of dam sites leading to changes in the original design after issue of work orders. In 15 out of 87 test-checked projects, improper survey before commencement of works resulted in an increase in cost of these projects by Rs 2,099 crore, besides delaying their completion.
