Water (Prevention and Control of Pollution) Act 1974

The Water (Prevention and Control of Pollution) Act 1974 is the first comprehensive environmental statute enacted by independent India, and it occupies a foundational place in the country's pollution-control architecture. Because water is a State subject under Entry 17 of List II (State List) of the Seventh Schedule of the Constitution, Parliament could not legislate directly. The Act was therefore enacted under Article 252(1), which permits Parliament to legislate on a State subject when two or more State Legislatures pass resolutions requesting it. Twelve States initially passed such resolutions, and the Act was adopted on 23 March 1974; other States subsequently acceded by passing their own resolutions, while non-acceding States were free to adopt it under Article 252(1). This constitutional route both empowered and constrained the statute, tying its national reach to the consent of participating States.

The Act's central mechanism is institutional: it creates a two-tier regulatory body. Section 3 establishes the Central Pollution Control Board (CPCB), and Section 4 establishes a State Pollution Control Board (SPCB) in each participating State. The CPCB advises the Central Government, coordinates the activities of State Boards, resolves disputes between them, and sets laboratory and standard-setting functions. The SPCBs carry the operational burden. Under Section 25, no person may establish or operate any industry, operation, or treatment plant likely to discharge sewage or trade effluent into a stream, well, sewer, or land without prior consent of the State Board — the regime universally known as "consent to establish" and "consent to operate." Section 26 extends this to pre-existing outlets. The Board may grant consent with conditions, refuse it, or revoke it.

Enforcement provisions give the boards investigatory and coercive teeth. Section 20 empowers boards to obtain information and survey waters; Section 21 authorises officers to take samples of effluent, subject to a prescribed procedure for splitting and sealing samples so they are admissible in court. Section 23 grants powers of entry and inspection. Section 24 imposes a general prohibition on knowingly causing or permitting poisonous, noxious, or polluting matter to enter a stream or well. Critically, Section 33A (inserted by the 1988 amendment) empowers boards to issue binding directions, including the power to close, prohibit, or regulate any industry and to stop or regulate the supply of electricity or water — a fast, non-judicial sanction. Section 32 allows emergency measures in cases of apprehended pollution. A companion statute, the Water (Prevention and Control of Pollution) Cess Act 1977, levied a cess on water consumed by specified industries and local authorities to fund the boards, though that Cess Act was repealed by the Goods and Services Tax regime in 2017.

In contemporary practice the boards operate from the Ministry of Environment, Forest and Climate Change (MoEFCC) in New Delhi for the CPCB, and from State capitals for SPCBs — the Maharashtra Pollution Control Board in Mumbai and the Tamil Nadu Pollution Control Board in Chennai being among the most active. CPCB classifications such as the "Red, Orange, Green, White" industry categories (notified in 2016) and its identification of polluted river stretches — over 350 stretches flagged in successive CPCB reports — structure SPCB consent decisions today. High-profile actions have included the 2017 National Green Tribunal directions on the Ganga and SPCB closure notices to tanneries and distilleries discharging into rivers.

The Water Act must be distinguished from adjacent instruments. The Environment (Protection) Act 1986, enacted under Article 253 following the Bhopal disaster, is an umbrella statute giving the Central Government residual and overriding powers; the Water Act remains the specialised, board-driven regime for aquatic pollution. The Air (Prevention and Control of Pollution) Act 1981, also enacted under Article 252, vested its functions in the same CPCB and SPCBs, deliberately reusing the Water Act's institutional scaffolding rather than creating new bodies. Unlike the National Green Tribunal Act 2010, which creates a judicial forum, the Water Act creates administrative regulators whose orders the NGT and High Courts review.

Several edge cases and controversies persist. The Article 252 foundation means a State that originally acceded cannot unilaterally withdraw, yet the patchwork of accession dates created early coverage gaps. Penalties under the original Act were widely criticised as inadequate, prompting the 1988 amendment that strengthened Sections 33A and the penalty provisions. Most significantly, the Jan Vishwas (Amendment of Provisions) Act 2023 and the Water (Prevention and Control of Pollution) Amendment Act 2024 decriminalised many minor offences, replacing imprisonment with monetary penalties adjudicated by an appointed adjudicating officer, and exempted certain categories of industry from the consent requirement — reforms that critics argue dilute deterrence while the Government frames them as easing compliance burdens.

For the working practitioner, the Water Act 1974 remains the operative law governing whether a factory, sewage plant, or municipal body may lawfully discharge effluent in India. Desk officers tracking industrial clearances, environmental lawyers litigating before the NGT, and analysts assessing India's water-quality governance all begin with its consent regime and the CPCB/SPCB structure it created. Its Article 252 origin is a recurring case study in Indian federalism, and the 2023–2024 decriminalisation amendments make it a live subject in debates over the trade-off between ease of doing business and environmental enforcement.
