National Waterways & IWAI
Why India is trying to move more cargo on its rivers, the cheapest transport mode almost nobody was using
Imagine a transport mode that is, per tonne of cargo moved, genuinely the cheapest and most fuel-efficient option available, cheaper than rail, considerably cheaper than road, covered under Logistics elsewhere on this site, and using rivers and canals that already exist without needing new land acquisition or construction, and discovering that India has historically used this mode, inland waterway transport, for only a tiny fraction of its total cargo movement compared to countries like the Netherlands or China.
The Inland Waterways Authority of India, IWAI, exists specifically to develop and maintain this underused transport mode, and India has formally declared 111 National Waterways, rivers and canal systems designated for navigation development, a considerably more ambitious scope than the handful of waterways that saw meaningful commercial use for decades before this systematic push.
The infrastructure challenge is genuinely significant, unlike roads or rail, rivers need consistent depth maintained through dredging, navigation aids, and terminal infrastructure at loading and unloading points, meaning declaring a waterway 'national' is only the first step, the actual dredging, terminal construction and vessel fleet development required to make a given waterway genuinely commercially viable takes years of sustained investment.
This inland waterway push connects directly to the 2025 tonnage tax expansion covered elsewhere on this site, extending tax predictability to inland vessel operators is specifically designed to attract the private capital needed to build out inland shipping fleets, exactly the kind of coordinated policy, infrastructure development plus favourable taxation, that determines whether India's genuinely large inland waterway potential actually converts into meaningful cargo volume shifted away from more expensive and more congested road transport.
