Waterways, Ports, Air Transport and Pipelines
National waterways NW-1 to NW-5, major ports, Sagarmala, Vadhavan, UDAN and airports, oil and gas pipelines, with Chhattisgarh's airports and gas link.
Prerequisites
- Roads and Railways — the land modes that feed ports and airports.
- Drainage System of India — the rivers that become national waterways.
- Major Industries of India — the refineries and fertiliser plants that pipelines serve.
The Hook: A Landlocked State and the Sea
Chhattisgarh has no coastline, yet its iron ore leaves India from Visakhapatnam and its coal and steel move towards Paradip. A flight from Raipur’s Swami Vivekananda Airport puts Delhi two hours away, and small UDAN flights now land at Bilaspur, Jagdalpur and Ambikapur. A natural gas pipeline from Mumbai to Jharsuguda crosses the state underground.
Water, air and pipelines are the “invisible” transport modes for most aspirants. Which waterways and ports should you know, how has air travel opened up, and where do pipelines run? This page covers them.
Why it matters: Prelims asks national waterway numbers and routes, port features (“which port is tidal?”, “which is corporatised?”), and scheme names (Sagarmala, UDAN). Mains P-V (GS-III) asks why inland water transport is underused and how ports and air connectivity drive growth.
Inland Water Transport (अंतर्देशीय जल परिवहन)
| Fact | Detail |
|---|---|
| Regulator | Inland Waterways Authority of India (IWAI), set up in 1986 under the IWAI Act, 1985; HQ Noida |
| National Waterways Act, 2016 | Declared 111 National Waterways (the 5 existing plus 106 new) |
| Operational | 29 national waterways were reported operational in 2024–25; IWAI plans many more |
| Advantages | Cheapest mode for bulk cargo per tonne-km, fuel-efficient, low emissions, no land acquisition |
| Limits | Seasonal water depth, siltation, braided channels, bridges with low clearance, lack of terminals and return cargo |
The first five national waterways
| NW | Route | River / canal | Length | Declared |
|---|---|---|---|---|
| NW-1 | Prayagraj (Allahabad) – Haldia | Ganga–Bhagirathi–Hooghly | 1,620 km (longest) | 1986 |
| NW-2 | Sadiya – Dhubri | Brahmaputra | 891 km | 1988 |
| NW-3 | Kottapuram – Kollam | West Coast Canal, with Champakara and Udyogmandal canals (Kerala) | about 205 km | 1993 |
| NW-4 | Kakinada – Puducherry stretch with the Godavari and Krishna | Canals and rivers (Andhra Pradesh, Tamil Nadu, Puducherry) | extended under the 2016 Act | 2008 |
| NW-5 | East Coast Canal with the Brahmani and Mahanadi delta | Odisha and West Bengal | 2008 |
Jal Marg Vikas Project: capacity augmentation of NW-1 on the Haldia–Varanasi stretch (about 1,390 km) with World Bank support, including multimodal terminals at Varanasi, Sahibganj and Haldia.
Ports (बंदरगाह)
India’s coastline was long given as about 7,516.6 km. A re-assessment by the National Hydrographic Office and the Survey of India using a finer scale revised it to 11,098.81 km (reported 2025). Expect questions on both figures and on why they differ (methodology, not new land).
| Category | Governed by | Number |
|---|---|---|
| Major ports | Union government; Major Port Authorities Act, 2021 | 12 (as of 2026); Vadhavan will be the 13th |
| Non-major ports | State maritime boards / state governments | About 200 |
The 12 major ports
| Coast | Port | Remember it for |
|---|---|---|
| West | Deendayal (Kandla), Gujarat | Tidal port; built after Partition to replace Karachi; renamed Deendayal in 2017; among the top ports by cargo |
| West | Mumbai, Maharashtra | Natural harbour; oldest and among the busiest |
| West | Jawaharlal Nehru Port (JNPA, Nhava Sheva), Maharashtra | India’s largest container port; built to decongest Mumbai |
| West | Mormugao, Goa | Iron ore exports |
| West | New Mangalore, Karnataka | Iron ore (Kudremukh historically), petroleum |
| West | Cochin (Kochi), Kerala | Natural harbour on Willingdon Island; shipyard and refinery |
| East | V.O. Chidambaranar (Tuticorin), Tamil Nadu | Southernmost major port |
| East | Chennai, Tamil Nadu | Artificial harbour; one of the oldest on the east coast |
| East | Kamarajar (Ennore), Tamil Nadu | First corporatised major port (a company, not a port trust) |
| East | Visakhapatnam, Andhra Pradesh | Deepest landlocked, protected port; ships iron ore from Bailadila (Chhattisgarh) |
| East | Paradip, Odisha | Iron ore, coal, fertilisers; near the Mahanadi mouth |
| East | Syama Prasad Mookerjee (Kolkata–Haldia), West Bengal | Riverine port on the Hooghly; Haldia dock built downstream to handle larger ships; renamed in 2020 |
New ports and schemes
| Item | Key facts |
|---|---|
| Vadhavan port | Palghar, Maharashtra; approved by the Union Cabinet in June 2024; deep natural draft (about 20 m); being built by a JNPA-led company; set to be the 13th major port, with the first phase targeted around the end of the decade |
| Vizhinjam port | Near Thiruvananthapuram, Kerala; India’s first deep-water container transshipment port; built under PPP (Adani Group and the Kerala government); commercial operations from December 2024, formally commissioned in May 2025. It is not a major port |
| Sagarmala Programme | Approved in 2015; port-led development through port modernisation, port connectivity, port-led industrialisation and coastal community development |
| Maritime India Vision 2030 and Maritime Amrit Kaal Vision 2047 | Long-term plans for port capacity, shipbuilding and coastal shipping |
Air Transport (वायु परिवहन)
| Fact | Detail |
|---|---|
| Nationalisation | 1953 (Air Corporations Act): Indian Airlines (domestic) and Air India International |
| Privatisation of Air India | Taken over by the Tata group in January 2022 |
| Airports Authority of India (AAI) | Constituted on 1 April 1995; manages most airports and air navigation services |
| Number of airports | About 160 operational airports (2025), up from 74 in 2014 (Ministry of Civil Aviation) |
| UDAN (Ude Desh ka Aam Naagrik) | Regional Connectivity Scheme launched in 2016 (first flight April 2017, Shimla–Delhi). By November 2025 about 651 routes had been operationalised, connecting 93 unserved or underserved airports, heliports and water aerodromes |
| Pawan Hans | Government helicopter service, important for the Northeast, islands and hills |
| Krishi UDAN | Air transport for farm produce, especially perishables from the Northeast and hilly areas |
Airports of Chhattisgarh
| Airport | City | Note |
|---|---|---|
| Swami Vivekananda Airport | Raipur (at Mana) | Main airport of the state; AAI |
| Bilasa Devi Kevat Airport | Bilaspur (Chakarbhatha) | Built by the Royal Indian Air Force in 1942, the state’s oldest airfield; UDAN flights |
| Maa Danteshwari Airport | Jagdalpur | UDAN flights link Bastar to Raipur, Hyderabad and other cities |
| Maa Mahamaya Airport | Ambikapur (Darima) | UDAN; serves Surguja |
Jagdalpur, Bilaspur and Ambikapur were developed under UDAN, with central funds sanctioned for their upgradation.
Pipelines (पाइपलाइन परिवहन)
Pipelines move crude oil, petroleum products and natural gas cheaply and continuously, with little loss and no road congestion. They are costly to build and hard to repair.
| Pipeline | Key facts |
|---|---|
| Naharkatiya – Nunmati (Guwahati) – Barauni | India’s first major crude oil pipeline, from the Assam oilfields to the Guwahati and Barauni refineries |
| Salaya – Viramgam – Mathura | Crude from the Gujarat coast to the Mathura refinery |
| Hazira – Bijaipur – Jagdishpur (HBJ) | GAIL’s first long-distance gas trunk line (Gujarat–MP–UP); fertiliser and power plants grew along it |
| Pradhan Mantri Urja Ganga | Jagdishpur–Haldia–Bokaro–Dhamra gas pipeline for eastern India |
| Mumbai – Nagpur – Jharsuguda (MNJPL) | GAIL natural gas pipeline, about 1,707 km, through Maharashtra, Madhya Pradesh, Chhattisgarh and Odisha; part of the National Gas Grid (“One Nation One Gas Grid”). Construction in Chhattisgarh was reported complete in 2025 |
Analysis for Mains: Making Water and Air Work
Why inland water transport is underused
- Physical: seasonal flow, siltation, shallow depths in the dry season, shifting channels in the Ganga and Brahmaputra.
- Infrastructure: few terminals and navigation aids; low bridges; poor road and rail links to jetties.
- Economic: lack of return cargo, few vessel operators, and cheaper, more flexible road transport.
What is being done: the National Waterways Act (2016), Jal Marg Vikas on NW-1, the Indo-Bangladesh Protocol route for the Northeast, river information systems, and the coastal shipping push under Sagarmala.
Ports: capacity, mechanisation and turnaround time have improved, but India still depends on foreign hubs (Colombo, Singapore) for container transshipment. Vizhinjam and Vadhavan aim to reduce that.
Air: UDAN has made flying affordable on regional routes, though many routes have struggled to stay viable after the subsidy period. Airports in Bastar and Surguja have improved access for administrators, tourists and patients.
Chhattisgarh angle: as a landlocked mineral state, Chhattisgarh’s competitiveness depends on port access (Visakhapatnam, Paradip), the Raipur–Visakhapatnam corridor, freight rail, and the gas grid that can supply cleaner fuel to Raipur–Bhilai industry and city gas.
Memory Tricks
Don’t Confuse
| This | vs | That |
|---|---|---|
| NW-1 — Ganga, Prayagraj–Haldia, 1,620 km | vs | NW-2 — Brahmaputra, Sadiya–Dhubri, 891 km |
| Kamarajar (Ennore) — first corporatised major port | vs | Kandla (Deendayal) — tidal port |
| Vadhavan — future 13th major port (Maharashtra) | vs | Vizhinjam — transshipment port, not a major port (Kerala) |
| AAI — airports, 1995 | vs | IWAI — inland waterways, 1986 |
| Bilasa Devi Kevat Airport — Bilaspur | vs | Swami Vivekananda Airport — Raipur |
| HBJ — gas, Gujarat–UP | vs | Salaya–Mathura — crude oil |
Common Mistakes
- “NW-1 runs from Haridwar to Haldia.” False. It runs from Prayagraj (Allahabad) to Haldia.
- “India has 13 major ports.” Not yet (as of 2026). There are 12; Vadhavan is being built as the 13th.
- “Vizhinjam is a major port.” False. It is a PPP port under the Kerala government, not one of the 12 major ports.
- “India’s coastline grew because of new land.” False. The jump from about 7,516 km to 11,098.81 km came from a new measurement method and finer scale.
- “Chhattisgarh has a national waterway in operation.” False as of 2026; its trade reaches the sea through Visakhapatnam and Paradip.

Level 3: Mains Answer Writing
Q1. (150–200 words) Inland water transport is the cheapest mode of transport, yet it carries a very small share of India’s freight. Explain why, and suggest measures.
Model answer outline
- Intro: India has 111 national waterways (2016 Act) but only a fraction (29 reported in 2024–25) are operational; IWT’s share of freight remains small.
- Reasons: seasonal flows and siltation; insufficient depth in the dry season; few terminals; low bridges; poor rail and road links to jetties; lack of return cargo; competition from flexible road transport.
- Measures: dredging and river training; Jal Marg Vikas (NW-1) multimodal terminals at Varanasi, Sahibganj and Haldia; river information systems; integration with Gati Shakti; coastal shipping under Sagarmala; incentives for cargo owners.
- Chhattisgarh angle: seasonal, rocky rivers make IWT unviable within the state; its benefit comes via coastal shipping from Visakhapatnam and Paradip.
- Conclusion: IWT can cut logistics cost and emissions, but only with year-round navigability and connected terminals.

Key Takeaways
- Learn NW-1 to NW-3 with river, route, length and year; 111 NWs exist on paper, far fewer are working.
- 12 major ports: tidal Kandla, container JNPA, corporate Ennore, deepest landlocked Vizag, riverine Kolkata.
- Vadhavan will be the 13th major port; Vizhinjam is India’s first transshipment port but not a major port.
- UDAN and AAI expanded airports to about 160; four Chhattisgarh airports, three under UDAN.
- Pipelines carry oil and gas; the Mumbai–Nagpur–Jharsuguda gas line links Chhattisgarh to the national gas grid.
