(i) Cost for development of River portion Rs. 2230 cr (Barrages- 1843 cr)
(ii) Cost of development of canal portion Rs. 1979 cr (Dredging- 1273 cr)
(iii) Total Cost Rs. 4209 crore

Period of Completion – 7 years

Barrages
To maintain LAD of 2 m in the Brahmani river all through the year, 5 barrages with height equal to the highest flood level are proposed to be constructed at every 26 km between Talcher and Jokadia. Each barrage will have a navigational lock to allow passage of two 500 tonne vessels at a time.

Cargo potential
Coal from Talcher to Dhamra and Paradip ports is the most important potential cargo for this waterway. Immediately after the development of the waterway, it is estimated in the DPR that about 11 million tonne of cargo can be transported per year which can go up to 23 million tonne in next 15 years or so.
