"Twenty projects have been found to be unviable in the feasibility studies and we will be dropping those. These were found unviable due to lack of cargo traffic potential and water scarcity," IWAI vice chairman Pravir Pandey told reporters here.
He said the 106 projects were identified based on proposals sent by the state governments and detailed studies were conducted to assess various aspects, with the economic rate of return being the most important.
It can be noted that there is an increased thrust on leveraging the opportunity presented by rivers and creeks as an ecofriendly, cheap and safe alternative for movement of goods around the country.
Pandey said over 80 projects are still feasible, detailed project reports have been made on 24 of them of which seven will be bidded out by November this year.
