3. Water Pollution Law | Preventing and Controlling the Pollution of Water Bodies

This is the 3rd post in Environmental Law, Unit III — Legal Framework for Environment Protection (the previous post covered wildlife protection law). This post covers the law relating to prevention and control of water pollution.

The Problem This Topic Solves

"Water" as a subject falls in the State List (Entry 17, List II), which meant Parliament had no direct power to legislate a uniform water-pollution law across India. Rather than leave water pollution control fragmented state-by-state, Parliament used the mechanism in Article 252 of the Constitution: once two or more State Legislatures passed resolutions requesting Parliament to legislate on their behalf, Parliament enacted a single central Act that then extended, and continues to extend, to any further State that adopts it by resolution.

The Water (Prevention and Control of Pollution) Act, 1974

Enacted under Article 252, the Water (Prevention and Control of Pollution) Act, 1974 is India's first pollution-specific central statute and the model on which the later Air Act, 1981 was built. Its core objectives are to prevent and control water pollution and to maintain or restore the wholesomeness of water, achieved through a permission-based regulatory system rather than blanket prohibition.

Central and State Pollution Control Boards

Sections 3 and 4 establish the Central Pollution Control Board (CPCB) and a State Pollution Control Board (SPCB) for every State that adopts the Act — the institutional backbone of India's entire pollution-control machinery, since the same Boards (with added powers) also administer the Air Act, 1981. The CPCB coordinates the state Boards, sets standards, and advises the Central Government; each SPCB is the primary regulator on the ground, responsible for granting or refusing consent, monitoring compliance, and taking enforcement action within its own state.

Prohibition on Polluting a Stream and the Consent Mechanism

Section 24 prohibits any person from knowingly causing or permitting any poisonous, noxious, or polluting matter to enter (directly or indirectly) any stream, well, sewer, or land, or from causing water pollution likely to render it a public health hazard. Sections 25 and 26 then impose the operative control: no person can establish any industry, operation, or process, or any treatment/disposal system, likely to discharge sewage or trade effluent into a stream, well, sewer, or land, without the prior consent of the State Board — commonly called Consent to Establish (CTE) before construction, and Consent to Operate (CTO) before actual operation begins. The Board can grant consent conditionally, subject to effluent-standard compliance, refuse it, or, once granted, revoke it for non-compliance.

Powers of the Board to Prevent and Restrain Pollution

• Section 32 — emergency measures: where pollution of a stream or well is imminent, the Board can itself carry out remedial measures and recover the cost from the polluter.
• Section 33 — the Board may apply to a court for an order restraining a person from causing pollution, where it apprehends that a discharge is about to occur or continue in contravention of the Act.
• Section 33A (inserted 1988) — the Board itself, without going to court, may issue directions in writing to any person, officer, or authority, including directions for closure, prohibition, or regulation of any industry, operation, or process, or stoppage/regulation of electricity or water supply. This is one of the Board's most powerful and frequently used tools, since it does not require prior court proceedings.

The Board's escalating enforcement powers: Section 32 (emergency self-help — the Board itself carries out remedial measures and recovers the cost from the polluter) → Section 33 (court-ordered restraint — the Board applies to a court for an order restraining the polluter) → Section 33A (direct closure order — the Board itself orders closure/regulation with no court needed, the strongest and most-used tool).

The Water Cess and Recent Decriminalisation

The Water (Prevention and Control of Pollution) Cess Act, 1977 supplements the 1974 Act by levying a cess on water consumed by specified categories of industries and local authorities, the proceeds of which fund the Pollution Control Boards' operations — industries that install and properly maintain effluent-treatment plants can claim a rebate on this cess, a built-in financial incentive for compliance. More recently, the Water (Prevention and Control of Pollution) Amendment Act, 2024 — a separate law, not the Jan Vishwas Act, 2023, which did not touch the Water Act at all — decriminalised several minor contraventions, replacing imprisonment-based offences (including the original Section 41) with civil penalties ranging from Rs. 10,000 to Rs. 15 lakh, adjudicated by an appointed Adjudicating Officer, in line with the government's broader "ease of doing business" decriminalisation drive across environmental statutes. Since the Water Act itself was extended state-by-state under Article 252, this 2024 amendment initially applies only to Himachal Pradesh, Rajasthan, and the Union Territories — other States must separately adopt it by resolution before it applies to them. More serious, continuing contraventions (such as persisting in an activity after being restrained under Section 33) remain punishable with imprisonment under the Act's surviving penal provisions.

• Governing Act: Water (Prevention and Control of Pollution) Act, 1974, enacted under Article 252 since water is a State subject.
• Sections 3/4 establish the CPCB and SPCBs, the institutional backbone of Indian pollution control (also administering the Air Act, 1981).
• Sections 25/26: no industry can discharge sewage/trade effluent without prior State Board consent (Consent to Establish, then Consent to Operate).
• Section 33A gives the Board direct power to order closure/regulation without first going to court — its most powerful enforcement tool.
• Water (Prevention and Control of Pollution) Cess Act, 1977 funds the Boards and rewards effluent-treatment compliance with a rebate.
• Water (Prevention and Control of Pollution) Amendment Act, 2024 decriminalised several minor Water Act offences, replacing imprisonment with adjudicated civil penalties.

A Practical Example

A textile dyeing unit begins operations and discharges untreated coloured effluent into a nearby stream without ever applying for Consent to Establish or Consent to Operate from the State Pollution Control Board. The Board can act under Section 33A and issue a written direction closing the unit's discharge outlet and, if necessary, directing the electricity supply to be disconnected — without needing to first approach a court — because operating without the mandatory consent under Sections 25/26 is itself a contravention independent of whether actual harm has yet been proved.

Quick Revision Points

• Governing Act: Water (Prevention and Control of Pollution) Act, 1974 (enacted under Article 252).
• CPCB/SPCB established under Sections 3/4.
• Sections 25/26: Consent to Establish and Consent to Operate required before any effluent-discharging activity.
• Section 32: Board's emergency remedial powers; Section 33: court-ordered restraint; Section 33A: Board's own direct closure/regulation power.
• Water Cess Act, 1977: cess on water consumption, rebate for effluent-treatment compliance.
• Water (Prevention and Control of Pollution) Amendment Act, 2024: decriminalised minor Water Act offences (Section 41 omitted), replaced with adjudicated penalties.
