Inland Waterway in India: National Waterways, Economic Importance, Challenges and Future Prospects
1. Introduction
The inland waterway in India represents one of the most cost-effective and environmentally sustainable modes of transport. Unlike road and rail, inland waterways use rivers, canals, and backwaters for the movement of goods and passengers. With rising logistics costs and increasing pressure on highways, India has renewed focus on developing its river-based transport network.
Currently, inland waterways account for less than 5% of India’s total freight transport, despite the country having over 14,500 km of navigable waterways. Recognising this untapped potential, the government has declared multiple National Waterways and launched large-scale infrastructure projects to strengthen inland water transport as part of multimodal logistics development.
2. What is Inland Waterway?
An inland waterway in India refers to navigable rivers, canals, backwaters, and creeks used for transporting goods and passengers within the country. Unlike maritime transport, which operates on seas and oceans, inland waterways function inside the landmass. They are especially suitable for moving bulk cargo such as coal, cement, food grains, and fertilisers, where speed is less critical but cost efficiency is important.
India has about 14,500 km of navigable waterways, including rivers like the Ganga and Brahmaputra, canal systems, and backwaters in states like Kerala. Transport through inland waterways is highly fuel-efficient—studies show that one litre of fuel can move cargo nearly 105 km by waterways, compared to about 85 km by rail and 24 km by road. This makes inland waterways an energy-saving and eco-friendly transport alternative.
3. Legal and Institutional Framework
The development of inland waterway in India is governed by a structured legal and institutional framework. The key authority is the Inland Waterways Authority of India (IWAI), established in 1986 under the Inland Waterways Authority of India Act, 1985. IWAI is responsible for regulation, development, and maintenance of national waterways across the country.
A major reform came through the National Waterways Act, 2016, which increased the number of declared National Waterways from 5 to 111. These waterways together cover nearly 20,000 km, although about 14,500 km are considered navigable. The Act marked a significant policy shift by expanding the scope of inland water transport and enabling systematic infrastructure development across multiple river systems in India.
4. Major National Waterways in India
The development of inland waterway in India is centred around key National Waterways that carry the bulk of cargo movement. Among the 111 declared waterways, a few are operationally significant due to better depth, infrastructure, and cargo demand.
4.1 NW-1: Ganga (Allahabad/Prayagraj to Haldia)
- National Waterway-1 (NW-1) is the longest and most important waterway in India, stretching about 1,620 km along the Ganga–Bhagirathi–Hooghly river system. It passes through Uttar Pradesh, Bihar, Jharkhand, and West Bengal.
- Under the Jal Marg Vikas Project, multimodal terminals have been developed to improve navigability. NW-1 accounts for a major share of inland cargo, including coal, fly ash, food grains, and cement.
4.2 NW-2: Brahmaputra
- National Waterway-2 runs along the Brahmaputra River in Assam for about 891 km (Dhubri to Sadiya). It is crucial for connectivity in the North-East region.
- Cargo movement on NW-2 includes fertilisers, food grains, and construction materials. Its strategic importance has increased due to improved India–Bangladesh river protocol routes.
4.3 NW-3: West Coast Canal
- National Waterway-3 covers about 205 km of the West Coast Canal in Kerala, connecting Kollam to Kottapuram. It includes rivers, canals, and backwaters.
- NW-3 is primarily used for passenger transport and movement of commodities like sand and construction materials. It supports regional tourism and local trade.
4.4 Other Important National Waterways
Other significant waterways include:
- NW-16 (Barak River) in the North-East
- Godavari and Krishna river stretches in southern India
- Protocol routes with Bangladesh improving eastern connectivity
Although 111 waterways are notified, only a limited number are currently viable for large-scale commercial cargo movement due to depth and infrastructure constraints.
5. Economic Importance of Inland Waterway in India
- The inland waterway in India plays a crucial role in reducing logistics costs and promoting sustainable transport. India’s logistics cost is estimated at around 13–14% of GDP, which is higher than many developed economies. Inland waterways offer a cheaper alternative, especially for bulk cargo such as coal, cement, food grains, and fertilisers.
- In terms of fuel efficiency, inland water transport is highly economical. One litre of fuel can move nearly 105 tonne-km by waterways, compared to about 85 tonne-km by rail and 24 tonne-km by road. The cost per tonne-kilometre by waterways is roughly ₹1–1.5, compared to ₹2.5–4 by road.
- By shifting cargo from congested highways to rivers, inland waterways help reduce traffic congestion, lower carbon emissions, and extend the lifespan of road infrastructure. Though currently contributing less than 5% of freight transport, the inland waterway in India holds strong potential for long-term multimodal logistics development.
6. Growth Prospects and Recent Data
The inland waterway in India has shown steady growth over the past decade due to focused policy support and infrastructure investment. Cargo movement on national waterways has increased significantly—from around 30 million tonnes (2014–15) to over 120 million tonnes in recent years, reflecting more than a threefold rise. This growth has been largely driven by operations on NW-1 (Ganga) and NW-2 (Brahmaputra).
The Jal Marg Vikas Project (JMVP) on NW-1, with an investment of over ₹5,000 crore, has improved fairway depth, navigation aids, and terminal infrastructure. Multimodal terminals at Varanasi, Sahibganj, and Haldia have strengthened cargo handling capacity.
Despite these gains, inland waterways still account for less than 5% of India’s total freight transport, compared to much higher shares in countries like China and the European Union. With continued investment and integration under initiatives like PM Gati Shakti, the inland waterway in India has strong potential to become a major pillar of multimodal transport.
7. Challenges in Development of Inland Waterway in India
- Seasonal variation in water depth: Many rivers experience low water levels during lean seasons, making year-round navigation difficult.
- Heavy siltation and shifting channels: Rivers like the Ganga and Brahmaputra carry high sediment loads, increasing dredging costs and maintenance needs.
- Limited terminal and cargo infrastructure: Only a few national waterways have fully developed multimodal terminals and mechanised loading facilities.
- Low share in freight movement: Inland waterways contribute less than 5% of total freight transport, indicating underutilisation.
- Environmental concerns: Dredging and vessel movement can disturb aquatic ecosystems and endangered species.
- Inter-state coordination issues: Rivers flow across multiple states, requiring coordinated policy and operational planning.
- Slow private sector participation: Limited PPP investment due to uncertain returns and high initial infrastructure costs.
- Last-mile connectivity gaps: Poor linkage between waterways, railways, and highways reduces overall efficiency of multimodal transport.
8. Government Initiatives for Inland Waterway in India
The Government of India has taken several steps to strengthen the inland waterway in India as part of multimodal transport and logistics reform.
- National Waterways Act, 2016: Expanded the number of declared National Waterways from 5 to 111, covering nearly 20,000 km of waterways across the country.
- Jal Marg Vikas Project (JMVP): Implemented on NW-1 (Ganga) with an investment of over ₹5,000 crore to improve fairway depth, navigation aids, and terminal infrastructure.
- Development of Multimodal Terminals: Terminals at Varanasi, Sahibganj, and Haldia have been developed to integrate waterways with road and rail networks.
- Sagarmala Programme Linkage: Promotes port-led development and connects inland waterways with coastal shipping and major ports.
- PM Gati Shakti National Master Plan: Aims to integrate inland waterways into a seamless multimodal logistics network.
- Inland Waterways Authority of India (IWAI): Strengthened institutional capacity for dredging, river training works, and digital river information systems.
These initiatives reflect the government’s commitment to increasing the share of inland water transport in India’s freight movement.
9. Way Forward
The future of the inland waterway in India depends on sustained infrastructure investment, ecological sensitivity, and seamless multimodal integration.
First, assured year-round navigability must be prioritised through scientific river management, improved dredging techniques, and real-time river information systems. Instead of excessive dredging, basin-level planning and sustainable river training methods should be adopted to reduce long-term maintenance costs.
Second, stronger integration with railways, highways, and ports under initiatives like PM Gati Shakti is essential to improve last-mile connectivity. Without efficient cargo transfer facilities, inland waterways cannot compete effectively with road and rail transport.
Third, greater private sector participation through public–private partnerships (PPP) can accelerate terminal development, vessel modernisation, and logistics services. Incentives for green vessels, LNG-powered barges, and low-emission transport systems can enhance sustainability.
Finally, environmental safeguards must remain central. Protection of aquatic biodiversity, pollution control, and community participation are critical to ensuring that the inland waterway in India grows as a sustainable and climate-resilient transport alternative rather than a purely extractive infrastructure project.
