Water, Air & Pipeline Transport — National Waterways, Major Ports, UDAN & HBJ Pipeline
NCERT India: People and Economy — Unit IV, Chapter 7 (Part 2)
7.2 Water Transport
Long before metalled roads or rails reached the heart of India, the country’s rivers were already its great highways — the Ganga carried boats from Patna to Murshidabad, the Brahmaputra carried tea from Assam to Calcutta, the Krishna and Godavari carried cotton and rice in the south. Today water transport? still matters because it is the cheapest mode for heavy and bulky cargo, the most fuel-efficient per tonne-kilometre and the most environment-friendly of all the major modes.
Definition — Water Transport
Water transport refers to the movement of passengers and cargo using water-bodies. It has two branches: (a) inland waterways — rivers, canals, backwaters and creeks; (b) oceanic waterways — coastal shipping along India’s 7,517-km coastline and international shipping across the Indian Ocean and beyond.
Inland Waterways
Inland waterways were the chief mode of transport before the advent of railways. They later faced tough competition from road and rail; in addition, the diversion of river water for irrigation made several stretches non-navigable for large parts of the year. India today has about 14,500 km of navigable waterways, contributing roughly 1% to the country’s transportation. This network includes rivers, canals, backwaters and creeks.
To develop and regulate inland water transport, the Inland Waterways Authority of India (IWAI) was set up in 1986. The aim is to create a wide waterways network and promote inland water transport as an economical, environment-friendly supplementary mode to road and rail. Under the National Waterways Act, 2016, a total of 111 inland waterways (including the five National Waterways declared earlier) were officially declared as National Waterways (NWs).
The Five Original National Waterways
| NW | Stretch | Length | Specification |
|---|---|---|---|
| NW-1 | Prayagraj — Haldia (Ganga–Bhagirathi–Hooghly) | 1,620 km | The most important Indian waterway; navigable by mechanical boats up to Patna and by ordinary boats up to Haridwar. Three sub-sections: Haldia–Farakka 560 km, Farakka–Patna 460 km, Patna–Prayagraj 600 km. |
| NW-2 | Sadiya — Dhubri (Brahmaputra) | 891 km | The Brahmaputra is navigable by steamers up to Dibrugarh (1,384 km from the mouth); shared by India and Bangladesh. |
| NW-3 | Kottapuram — Kollam (West Coast Canal) | 205 km | Includes 168 km of West Coast Canal plus the Champakara Canal (14 km) and the Udyogmandal Canal (23 km). Threads through the Kerala backwaters. |
| NW-4 | Specified stretches of Godavari & Krishna with Kakinada–Puducherry canal | 1,078 km | Connects the eastern deltas with the coastal canal network. |
| NW-5 | Mahanadi & Brahmani delta channels with East Coast Canal | 588 km | Includes the Matai river and East Coast canals; supports cargo movement from Odisha’s ports. |
The Inland Waterways Authority has identified 10 additional inland waterways for upgradation. The Kerala backwaters (Kayal) have a special significance: they are not only a cheap means of transport but also a major tourist draw — the famous Nehru Trophy Boat Race (Vallam Kali) is held in these backwaters every year.
Fig 7.4 — National Waterways NW-1 to NW-5 (Schematic)
Explore — Why is NW-1 the most important waterway?
NW-1 covers 1,620 km from Prayagraj to Haldia. List four reasons why this stretch is more economically important than NW-3 (just 205 km) even though both have been declared National Waterways.
Hint:
- NW-1 passes through the densely populated Gangetic plain — a vast captive market.
- It links India’s busiest port (Haldia) with North India’s industrial hubs (Kolkata-Kanpur-Allahabad).
- It moves bulk cargo — coal, foodgrains, cement — over long distances at low cost.
- It is being upgraded under the Jal Marg Vikas Project for round-the-year navigability.
Oceanic Routes
India has a long coastline of approximately 7,517 km, including the islands. Twelve Major Ports? and over 200 minor ports provide infrastructural support to oceanic routes. Approximately 95 per cent of India’s foreign trade by volume and 70 per cent by value moves through ocean routes — a single statistic that explains why a country’s ports are sometimes called its ‘windows to the world’. Apart from international trade, oceanic routes are also used for transport between India’s far-flung islands (Andaman & Nicobar, Lakshadweep) and the mainland.

The 12 Major Ports of India
Major Ports are administered directly by the Government of India under the Major Port Authorities Act, 2021. They are the country’s commercial gateways. The list (with the coast each is on) appears below.
West Coast (5)
Kandla, Mumbai, JNPT (Nhava Sheva), Mormugao, New Mangalore, Kochi. Mumbai is the largest port and JNPT is the country’s biggest container terminal.
East Coast (6)
Tuticorin, Chennai, Ennore, Visakhapatnam, Paradip, Haldia, Kolkata. Visakhapatnam handles iron-ore exports; Paradip serves the Odisha-Jharkhand mineral belt.
JNPT — The Container Hub
Jawaharlal Nehru Port Trust (Nhava Sheva, Maharashtra) is India’s premier container port and the destination terminal for the Western Dedicated Freight Corridor.
Sagarmala (2015)
Flagship programme of the Ministry of Ports, Shipping & Waterways. Aims at port-led development — modernisation, port-rail/road connectivity and coastal economic zones.

7.3 Air Transportation
Air transport is the fastest mode of moving passengers and cargo. By minimising travel time, it has effectively shrunk distances — an unforgivingly important advantage for a vast and physiographically diverse country like India.
Beginning — 1911
Civil aviation in India began in 1911 when an airmail operation commenced over a tiny distance of 10 km between Prayagraj (Allahabad) and Naini. The real expansion happened only after Independence. Today the Airport Authority of India (AAI) is responsible for safe, efficient air-traffic and aeronautical communication services in Indian airspace.
From Tata Airlines (1932) to Indian Airlines & Air India
The first scheduled commercial airline in India was Tata Airlines, founded in 1932 — later renamed Air India in 1946. After Independence, civil aviation was nationalised in 1953: Air India International handled overseas operations and Indian Airlines handled domestic and neighbouring routes. The sector was opened to private players after 1991, leading to the rise of carriers such as IndiGo, SpiceJet, Air Asia, Vistara, GoAir and the revived Air India under Tata Group ownership (2022).
Major Airports in India
Today the country has 137+ operational airports. The five busiest are:
| Airport | City | IATA Code | Note |
|---|---|---|---|
| Indira Gandhi International | Delhi | DEL | Busiest airport in India; Terminal 3 is among the world’s largest passenger terminals. |
| Chhatrapati Shivaji Maharaj International | Mumbai | BOM | Second-busiest; financial-capital gateway. |
| Kempegowda International | Bengaluru | BLR | Major hub for South Indian and South-East Asian routes. |
| Rajiv Gandhi International | Hyderabad | HYD | Modern PPP airport — major cargo hub for pharma exports. |
| Chennai International | Chennai | MAA | Important southern gateway. |
| Netaji Subhas Chandra Bose International | Kolkata | CCU | Eastern India’s major airport. |
UDAN — Flying for the Common Citizen
UDAN — Ude Desh ka Aam Nagrik (2017)
UDAN? is the Regional Connectivity Scheme (RCS) launched by the Ministry of Civil Aviation in 2017. It is described by the Government as “a first-of-its-kind scheme globally”. Its central idea is to encourage airlines to operate flights on regional and remote routes by offering policy incentives, capped fares for half the seats, and viability gap funding — making air travel affordable for the common citizen and reviving disused airstrips across the country.
Pawan Hans — Helicopter Services
Pawan Hans Limited is the public-sector helicopter operator that runs services in hilly terrain and is widely used by tourists in the North-Eastern states. In addition, Pawan Hans provides helicopter services to the petroleum sector (offshore rig support) and for tourism. Helicopters are uniquely suited to serve oil rigs in the Bombay High and offshore Krishna–Godavari basin.
Discuss — Should small towns get airports?
Form two groups. Group A defends the position: “UDAN is wasting public money — small towns will never have enough flyers”. Group B defends the opposite. Cite the chapter to support your stand.
Group A’s strongest points: Heavy capex per passenger; aircraft fleets get spread thin; tier-3 routes need decade-long subsidy. Group B’s strongest points: Cuts intra-state travel time, attracts tourism investment, allows urgent medical evacuation, drives demand-creation as cities like Kannur, Belagavi and Hubli have shown post-UDAN. The class can vote on which is more compelling and tabulate the supporting evidence on the board.
7.4 Oil & Gas Pipelines
Pipelines are the most convenient and efficient mode of transporting liquids and gases over long distances. Even solids can be moved by pipeline once they are converted into slurry (e.g. iron-ore concentrate). They have low operating cost, are weather-proof, and they free road and rail capacity for general cargo.
Two Public-Sector Builders — OIL and GAIL
Oil India Limited (OIL)
Set up under the Ministry of Petroleum & Natural Gas. Incorporated as a company in 1959, OIL handles exploration, production and transportation of crude oil and natural gas. It built Asia’s first cross-country pipeline — 1,157 km from Naharkatiya (Assam) to Barauni (Bihar); later extended to Kanpur in 1966.
GAIL (India) Ltd
Set up as a Public Sector Undertaking in 1984 to transport, process and market natural gas for economic use. GAIL operates India’s national gas grid and is therefore the keystone of the country’s gas economy.
The HBJ Gas Pipeline — A National Artery
HVJ / HBJ Pipeline — The First & Largest
The first 1,700 km long Hazira–Vijaipur–Jagdishpur (HVJ / HBJ) cross-country gas pipeline, constructed by GAIL (India), connected the Bombay High and Bassein gas fields with various fertiliser, power and industrial complexes in western and northern India. This single artery kick-started India’s gas market.
The country’s gas infrastructure has since expanded over ten times — from 1,700 km to 18,500 km of cross-country pipelines — and is targeted to soon reach over 34,000 km as a National Gas Grid linking every gas source and consuming market, including the North-Eastern states.
Fig 7.6 — HVJ (HBJ) Gas Pipeline: Route Schematic
Other Major Pipelines
- Salaya–Mathura — carries imported crude from the Salaya terminal on the Gujarat coast (off Mundra) to Mathura refinery; further extended to Panipat & Karnal.
- Naharkatiya–Noonmati–Barauni — Asia’s first cross-country pipeline by Oil India.
- Mumbai High–Mumbai–Ankleshwar — pipes Bombay High oil to mainland refineries.
- Kandla–Bhatinda — long product pipeline serving northwest fuel demand.
- National Gas Grid — under expansion to 34,000 km, linking every state’s gas market.
Source — Pipelines vs. Trucks
From the chapter
“Pipelines are the most convenient and efficient mode of transporting liquids and gases over long distances. Even solids can also be transported by pipelines after converting them into slurry.”
— NCERT, Class 12, Ch.7
Q. List two advantages and two disadvantages of pipeline transport relative to road tankers.
Answer guide:
Advantages: (i) lowest unit transportation cost for liquids/gases over long hauls; (ii) weather-proof — functions in monsoons, snow and night when trucks may halt; (iii) zero road congestion; (iv) lower CO₂ per tonne-km than diesel trucks.
Disadvantages: (i) huge capital cost — route once fixed cannot be re-routed easily; (ii) leakage and sabotage risks (terror attacks on pipelines); (iii) cannot serve last-mile rural pumps; (iv) only liquids, gases or slurry — not solids in their natural form.
Competency-Based Questions — Water, Air & Pipelines
Case Study: India has 14,500 km of navigable inland waterways, a 7,517-km coastline with 12 Major Ports, 137+ airports and an 18,500-km gas pipeline grid — soon to expand to 34,000 km. About 95% of foreign trade by volume moves by sea. UDAN, launched in 2017, is reviving regional aviation. The HBJ (Hazira–Vijaipur–Jagdishpur) pipeline carries gas from Bombay High to fertiliser plants in north India. NW-1 (Prayagraj–Haldia, 1,620 km) is being modernised under the Jal Marg Vikas Project.
1. National Waterway No. 1 (NW-1) lies on which river system?
L1 Remember
Answer: (b) Ganga–Bhagirathi–Hooghly system. NW-1 is 1,620 km long, the most important Indian waterway.
2. Why does 95% of India’s foreign trade by volume move by sea, even though air freight is much faster?
L4 Analyse
Answer: Foreign trade by volume is dominated by bulk commodities — crude oil, coking coal, iron ore, fertilisers, foodgrains, machinery. The freight cost per tonne-km on a Capesize bulk carrier is a small fraction of the air-cargo equivalent. Ships also carry the giant volumes that air-cargo simply cannot — a single VLCC tanker moves 200,000 tonnes of crude in one trip. Air is reserved for high-value, low-bulk cargo (electronics, pharma, perishables) where speed beats cost. Hence the volume share is sea-dominant.
3. Compare the strengths and weaknesses of pipeline transport with road and rail for moving petroleum products.
L5 Evaluate
Answer: Strengths of pipelines: very low unit transport cost; continuous flow; weather-proof; minimal accidents; lowest carbon footprint per tonne-km. Weaknesses: huge upfront capex; rigid alignment; only liquids, gas, slurry; vulnerable to sabotage. Road tankers are flexible but expensive and emission-heavy. Rail tankers are cheaper than road but require terminals and trans-shipment. Net: trunk-line crude/product is best by pipe, regional dispatch by rail-tanker, last-mile by road tanker. The HBJ network exemplifies this design.
4. Imagine you are designing a new National Waterway. Which river basin would you choose, and what three engineering challenges would you anticipate?
L6 Create
Model answer: Choose the Yamuna from Allahabad to Agra, integrating with NW-1. Challenges: (i) seasonal water depth — need barrages and dredging to maintain 2 m least available draft; (ii) urban pollution loading — environmental clearance and effluent treatment plants upstream; (iii) competing demand from irrigation and Delhi water supply — need a basin-wide allocation agreement among Haryana, UP and Delhi. Once stabilised, the corridor can move sand, cement and foodgrains from the Doab to NCR at a fraction of road cost.
HOT — A consultant claims UDAN is ‘a first-of-its-kind scheme globally’. Critically evaluate the claim.
L5 Evaluate
Answer: The Government’s Press Information Bureau does describe UDAN as “a first-of-its-kind scheme globally”, citing the unique combination of (i) reverse-bidding for routes, (ii) capping fares for half the seats, (iii) Viability Gap Funding pooled from a tiny levy on busy routes, and (iv) an explicit objective of making air travel affordable for the ‘aam nagrik’. However, regional connectivity subsidies in the EU (Public Service Obligation routes) and in Australia (Remote Air Services Subsidy) have similar elements. So UDAN is best described as a uniquely Indian package — not unprecedented in concept, but unmatched in scale: it has revived 70+ disused airports, including Pakyong (Sikkim) and Tezu (Arunachal). The verdict: marketing rhetoric aside, UDAN’s real distinction is geographic reach, not procedural novelty.
Assertion & Reason — Water, Air & Pipelines
Assertion (A): NW-1 from Prayagraj to Haldia is one of the most important inland waterways in India.
Reason (R): It is 1,620 km long, navigable by mechanical boats up to Patna and by ordinary boats up to Haridwar.
Reason (R): It is 1,620 km long, navigable by mechanical boats up to Patna and by ordinary boats up to Haridwar.
Correct: (A) — NW-1’s length and navigability through the densely populated Gangetic plain are precisely what give it its primacy.
Assertion (A): Pipelines are the most efficient mode of transporting petroleum and natural gas over long distances.
Reason (R): They run continuously, are weather-proof and have very low operating costs per tonne-kilometre.
Reason (R): They run continuously, are weather-proof and have very low operating costs per tonne-kilometre.
Correct: (A) — Continuous flow, all-weather availability and low operating cost per tonne-km are the precise reasons why pipelines outperform rail and road for crude oil and natural gas trunk movement.
Assertion (A): India’s gas-pipeline grid is targeted to expand to over 34,000 km in the coming years.
Reason (R): The HVJ (Hazira-Vijaipur-Jagdishpur) pipeline runs from the Bombay High & Bassein gas fields to fertiliser, power and industrial complexes in western and northern India.
Reason (R): The HVJ (Hazira-Vijaipur-Jagdishpur) pipeline runs from the Bombay High & Bassein gas fields to fertiliser, power and industrial complexes in western and northern India.
Correct: (B) — Both statements are true. But the planned 34,000 km expansion is driven by the goal of a national gas market reaching every State (including the North-East), not by the existence of the HVJ alone. R is a true historical fact, not the reason for A.
