Inland Waterways

Inland water transport is a concurrent subject under the Constitution of India. However, entry 24 of the Union List empowers the Central Government to declare specific inland waterways as “National Waterways” (NWs) for regulation and development by Parliament.

Inland Waterways Authority of India (IWAI)

Statutorily established under the Inland Waterways Authority of India Act, 1985, the IWAI came into existence on October 27, 1986. Headquartered in Noida, Uttar Pradesh, with regional offices across major river basins, it functions under the Ministry of Ports, Shipping and Waterways. The IWAI is the apex nodal agency responsible for the development, maintenance, and regulation of National Waterways for shipping and navigation.

The National Waterways Act, 2016

This landmark legislation repealed the individual acts that governed the first five national waterways. It declared 106 additional inland waterways across the country as National Waterways, raising the total number of statutory National Waterways in India to 111. This act aimed to create a robust legislative baseline to tap into India’s estimated 14,500 km of navigable rivers, canals, backwaters, and creeks.

Macro-Economic Significance and Multiplier Effect

Cost Efficiency and Energy Dynamics

Inland Water Transport (IWT) is economically superior to road and rail networks regarding fuel consumption and operational costs.

• Fuel Consumption: One liter of fuel can move 24 tonne-kilometers of freight by road, 95 tonne-kilometers by rail, and up to 215 tonne-kilometers by inland waterways.
• Freight Tariffs: The operational cost of moving cargo via inland waterways is estimated at roughly ₹0.50 per tonne-km, compared to ₹1.00 per tonne-km by rail and ₹1.50 per tonne-km by road.

Environmental and Congestion Relief

IWT acts as a low-carbon transport mode, emitting significantly less greenhouse gas per tonne-kilometer than surface logistics. Its development directly mitigates urban gridlocks, reduces highway maintenance expenditure, and lowers the national crude oil import bill.

Logistics and Hinterland Connectivity

Developing waterways enhances multi-modal integration by connecting landlocked agrarian and mineral-rich hinterlands with maritime ports, advancing the objectives of the National Logistics Policy and the PM GatiShakti National Master Plan.

Out of the 111 declared National Waterways, primary development and commercial cargo shipping are concentrated across specific operational routes.

Infrastructure Modernization Projects and Key Initiatives

Jal Marg Vikas Project (JMVP)

Implemented by the IWAI with technical and financial assistance from the World Bank, the JMVP aims to capacity-augment the Prayagraj-Haldia stretch of National Waterway-1. The project targets enabling the commercial navigation of vessels with a capacity of 1,500 to 2,000 DWT (Deadweight Tonnage) by ensuring a Least Available Depth (LAD) of 3 meters in prioritized stretches. Key components include:

• Multi-Modal Terminals (MMTs): Developed at Varanasi (Uttar Pradesh), Sahibganj (Jharkhand), and Haldia (West Bengal).
• Inter-Modal Terminals (IMTs): Formulated at Kalughat and Ghazipur.
• Farakka Navigation Lock: Construction of a modern, parallel navigation lock to minimize vessel turnaround time.

Indo-Bangladesh Protocol (IBP) Route

India and Bangladesh share a long-standing Protocol on Inland Water Transit and Trade. This framework allows vessels of both nations to utilize designated waterway routes for bilateral commerce and transit between the Indian mainland and the North-Eastern Region (NER) via the Bangladesh waterway network. Key ports of call include Kolkata, Haldia, Pandu, Karimganj, and Ashuganj.

Arth Ganga Concept

Introduced as a sustainable economic model along the Ganga basin under the JMVP, it focuses on channeling the economic spillover of inland waterways into local communities. It incorporates:

• Zero Waste Efficient Transportation.
• Promotion of local economic zones, floating farmers’ markets (Jalaj), and community jetties.
• Enhancing religious and cultural river cruise tourism.

Sagarmala Programme Integration

Inland waterways are integrated with coastal shipping under the “Coastal Shipping and Inland Water Transport” pillar of the Sagarmala Programme. This ensures that river terminals act as feeder nodes to major maritime ports, enabling seamless containerized movement from factories to deep-sea vessels.

Core Challenges and Structural Bottlenecks

Siltation and Depth Fluctuations

Indian rivers exhibit extreme seasonal discharge variations. High siltation rates during monsoons lead to the formation of riverbed shoals, drastically reducing the Least Available Depth (LAD) during dry summer months and disrupting large commercial vessel navigation.

Inadequate Infrastructure and First/Last-Mile Connectivity

The deficit of automated night-navigation systems, modern river terminals with mechanized cargo handling facilities, and robust rail-road connectivity at river banks increases multi-modal transfer times.

Environmental and Riparian Ecosystem Concerns

Continuous capital and maintenance dredging to maintain navigation channels disrupts riverine ecosystems, breeding grounds for aquatic fauna (such as the endangered Gangetic Dolphin), and localized fishing livelihoods.

Upstream Water Diversion

Extensive diversion of river water for agricultural irrigation via canals and industrial utilization upstream reduces the volumetric discharge required downstream to sustain navigable channels.

Key Facts and Trivia for Civil Services Prelims

First National Waterway Modification

The National Waterways Act, 2016 merged several contiguous river stretches. NW-1 is currently the longest operational national waterway in India, spanning 1,620 kilometers from Uttar Pradesh to West Bengal.

PANKH Portal

The IWAI launched the PANKH (Portal for Asset and Navigation Information Knowledge Hub) to provide real-time data regarding the availability of berths, least available depth, vessel tracking, and cargo tariffs across national waterways to increase ease of doing business.

CAR-D (Cargo Data) Portal

A specialized web-based portal designed to compile and analyze cargo and cruise vessel data on a real-time basis, promoting transparency among shippers, barge operators, and terminal managers.

Kaladan Multi-Modal Transit Transport Project

While situated outside geographic India, this critical strategic project connects the eastern Indian seaport of Kolkata with the Sittwe seaport in Rakhine State, Myanmar, by sea. From Sittwe, the transit routes move upstream along the Kaladan River via inland water transport to Paletwa, and subsequently by road into Mizoram, bypassing the narrow Siliguri Corridor.
