National Waterways Act 2016

Topic: Transport and Communication in India · NCERT: Class 10, Ch 7 "Lifelines of National Economy"; Class 12, Ch 7 "Transport and Communication"

Meaning

The National Waterways Act, 2016 is a law passed by Parliament and enacted on 25 March 2016. It declared 111 inland waterways as National Waterways (NWs): the 5 old NWs plus 106 new ones, so that the Centre can develop them for cargo and passenger transport [2].

• Why it matters: inland water transport is the cheapest, most fuel-efficient and most eco-friendly way to move heavy goods.
• Waterways carry only about 2% of India's freight today. The Act puts the legal base in place to raise this share towards the 5% target [2].

Explanation

What a "National Waterway" is

• National Waterway (NW): a waterway that Parliament declares by law.
• Once declared, it becomes a Union List subject, so the Centre develops and regulates it.

• Waterways that are not declared stay with the states.

• Inland waterways are water routes inside a country that are not part of the sea. They include:

• rivers
• canals
• backwaters (kayals): quiet coastal lagoons running along the sea, as in Kerala

• creeks: narrow arms of the sea reaching into the coast, as on the Maharashtra and Gujarat coasts

• A waterway counts as navigable when boats of at least 50 tonnes can use it in normal conditions [2].

• Three types of waterway are covered [2]:
• Open river waterway: a natural, free-flowing river kept deep with small works. Example: Brahmaputra (NW-2).
• Canalised waterway: a river split into calmer sections by locks (gated chambers that raise or lower boats) and dams. Example: the Ganga at the Farakka lock (NW-1).
• Canal: a man-made channel dug for boats. Examples: West Coast Canal (NW-3) and Buckingham Canal (NW-4).

Why the Act was needed: cause → process → result

• Cause: the old network had declined.
• Before 1853, rivers like the Ganga and Brahmaputra were the chief mode of transport.
• Railways and roads were faster and could be used all year.
• Barrages and canals took river water for irrigation, so less water flowed downstream.
• Siltation (sand and mud settling on the riverbed) and a low dry-season flow made long stretches non-navigable.

• Waterways ended up carrying only about 1% of traffic (NCERT).

• Process: a single law instead of one Act per river.

• Before 2016, each of the 5 old NWs had been declared by a separate Act.

• The 2016 Act brought them together and added 106 new waterways in one step [2].

• Result: a large national network.

• 111 NWs, 20,187 km, spread over 23 states and 4 Union Territories [2].
• 32 NWs (5,155 km) were operational as of March 2026. The plan is to reach 52 within 5 years [2].
• The Union Budget 2026-27 promises 20 new operational NWs over the next 5 years [2].

What it takes to make a declared NW "operational"

• Declaring a waterway is only the first step. It becomes operational only when it has three things [2]:
• a fairway: a channel wide and deep enough for boats
• terminals linked to road and rail

• navigational aids: buoys, lights and markers

• Dredging (removing sand and silt from the riverbed) keeps the fairway deep [2].

• Who builds them: the Inland Waterways Authority of India (IWAI).
• It was set up under the IWAI Act, 1985 and formed on 27 October 1986 [2].
• It works under the Ministry of Ports, Shipping and Waterways, with its headquarters in Noida (UP).
• It is also the competent authority under the Inland Vessels Act, 2021, which gives inland vessels one uniform set of rules across India [2].

The advantages the Act aims to use

• Water transport uses about 3–6 times less energy than road and up to 2 times less than rail [2].
• One inland vessel of about 2,000 tonnes can replace nearly 125 trucks of 16 tonnes each [2].
• It needs very little land, takes load off crowded roads and railways, and supports Ro-Ro ferries (vehicles drive straight onto the boat) and tourism [2].

Where it occurs

• Coverage: 23 states and 4 UTs. The law is run by IWAI under the Ministry of Ports, Shipping and Waterways, and was enacted in 2016 [2].
• The five original NWs, now included in the Act:
• NW-1: Ganga–Bhagirathi–Hooghly, Prayagraj–Haldia, 1,620 km. It runs through UP, Bihar, Jharkhand and West Bengal.
• NW-2: Brahmaputra, Sadiya–Dhubri, 891 km, all in Assam.
• NW-3: West Coast Canal, Kottapuram–Kollam, 205 km, Kerala. It includes the Champakara (14 km) and Udyogmandal (23 km) canals.
• NW-4: Godavari and Krishna stretches with the Kakinada–Puducherry canals, 1,078 km. It runs through Andhra Pradesh, Tamil Nadu and Puducherry.

• NW-5: Brahmani, Matai, Mahanadi–Brahmani delta channels and the East Coast Canal, 588 km, in Odisha and West Bengal.

• Examples of new NWs declared under the Act [2]:

• Goa: Mandovi (NW-68), Zuari (NW-111) and Cumberjua (NW-27). They carry iron ore barges to Mormugao port.
• Barak (NW-16), Assam, with terminals at Badarpur and Karimganj.
• Sundarbans (NW-97), West Bengal: mangrove channels and a cruise route.

• Kerala backwaters: NW-8 (Alappuzha–Changanassery) and NW-9 (Alappuzha–Kottayam–Athirampuzha).

• Projects built on the declared network:

• Jal Marg Vikas Project on NW-1 (Varanasi–Haldia, World Bank-aided) [2].
• Jalvahak Cargo Promotion Scheme (2024) on NW-1, NW-2 and NW-16 through the Indo-Bangladesh Protocol Route [2].

Don't confuse with

• IWAI Act, 1985: it created the body (IWAI) that develops waterways. The NW Act, 2016 declares which waterways are national.
• Inland Vessels Act, 2021: it sets uniform rules for boats and vessels, not for routes. IWAI is its competent authority [2].
• Declared vs operational NW: 111 are declared by law, but only 32 were working as of March 2026 [2]. A waterway is operational only once it has a fairway, terminals and navigational aids.
• Indo-Bangladesh Protocol Route (1972): this is an international agreement for trade and transit through Bangladesh's rivers. It is not a declaration under the 2016 Act, though it links NW-1, NW-2 and NW-16.

Prelims Hooks

• NW Act, 2016 = 111 NWs = 5 old + 106 new, covering 20,187 km in 23 states + 4 UTs [2].
• The Act was enacted on 25 March 2016. 32 NWs (5,155 km) were operational as of March 2026 [2].
• Trap on lengths: NW-1 (1,620 km) > NW-4 (1,078 km) > NW-2 (891 km) > NW-5 (588 km) > NW-3 (205 km).
• Number–waterway matches: Barak = NW-16; Sundarbans = NW-97; Mandovi = NW-68; Zuari = NW-111; Cumberjua = NW-27 [2].
• A National Waterway is declared by Parliament and falls in the Union List. Undeclared waterways are left to the states.
• IWAI was set up under the IWAI Act, 1985, formed in 1986, and is headquartered in Noida [2].

Mains Points

• Why the Act was needed (GS-I/III):
• Railways from 1853, irrigation barrages that cut downstream flow, and siltation pushed waterways down to about 1–2% of traffic [2].

• Before 2016, the Centre had only 5 declared NWs. The Act widened central control to 111, which made planned national investment possible.

• What it delivers (GS-III, infrastructure and environment):

• Cargo on NWs grew from 18.10 MMT (FY 2013-14) to about 145.5 MMT (FY 2024-25) [3].
• Coal, ores, sand and fly ash make up over 68% of this cargo [3]. These bulky, low-value goods suit cheap, low-carbon water transport.

• It links with JMVP, Sagarmala and PM Gati Shakti. The targets are over 200 MMT by 2030 and over 500 MMT by 2047 [2][3].

• Gaps between law and reality:

• Only 32 of 111 NWs are operational [2].
• Problems remain:
  • low dry-season depth beyond Patna on NW-1
  • heavy siltation on the Brahmaputra
  • pontoon bridges and low bridges that block vessels
  • few return cargoes
  • harm to river ecology from dredging, such as to the Gangetic dolphin habitat
• Growth is fast but starts from a low base.
