Addressing Water Pollution: Legal Framework and Challenges

India’s rivers, lakes, and groundwater feed over a billion lives – for drinking, farming, and daily survival. Yet today, the Central Pollution Control Board (CPCB) identifies 351 polluted river stretches across the country, and an estimated 70% of India’s surface water is contaminated due to untreated sewage and industrial waste. Water pollution is not merely an environmental concern – it is a public health emergency, a constitutional issue, and a governance challenge. Understanding the legal framework that governs water quality in India is essential for anyone studying law, public administration, or rural governance.

Why India needed a dedicated water pollution law 🔗

Before 1974, India had no comprehensive national legislation specifically targeting water pollution. Post-independence industrialisation and rapid urbanisation led to unchecked discharge of industrial effluents and domestic sewage into rivers and lakes. The 1972 Stockholm Conference on Human Environment gave international momentum to environmental protection, and India responded by enacting its first dedicated water pollution statute. Since water is listed as a State subject under the Constitution, Parliament drew its legislative competence from Article 252, which allows it to legislate on state-list matters when two or more states pass resolutions requesting it to do so. Twelve states initially passed such resolutions, enabling the central enactment of the Water (Prevention and Control of Pollution) Act, 1974.

The Water (Prevention and Control of Pollution) Act, 1974: an overview 🔗

The Water (Prevention and Control of Pollution) Act, 1974 (commonly called the Water Act) is India’s foundational legislation on water quality. Its stated purpose is to prevent and control water pollution and to maintain or restore the “wholesomeness” of water – meaning its fitness for consumption and use by living organisms. The Act covers a broad definition of water bodies: rivers, streams (flowing or dry), inland waters whether natural or artificial, subterranean waters, and tidal or sea waters as notified by the state. It comprises 64 sections arranged across 8 chapters, dealing with institutional setup, powers of boards, pollution control measures, penalties, and miscellaneous provisions.

The core mechanism of the Act is a consent administration system. Before any industry or local body can discharge sewage or trade effluents into any water body, sewer, or land, it must obtain the prior consent of the State Pollution Control Board (SPCB). This consent may be granted with specific conditions and a validity period, or refused with written reasons. Section 24 further prohibits the use of streams or wells for disposal of polluting matter. Any violation of these provisions under the original Act was punishable with imprisonment of one and a half to six years, along with a fine.

Central and State Pollution Control Boards: the enforcement backbone 🔗

The institutional heart of the Water Act lies in two sets of bodies: the Central Pollution Control Board (CPCB) and the State Pollution Control Boards (SPCBs).

Central Pollution Control Board 🔗

The CPCB was constituted under Section 3 of the Act and is headquartered in New Delhi under the Ministry of Environment, Forest & Climate Change (MoEFCC). Its primary function under Section 16 is to advise the Central Government on water pollution matters, coordinate the activities of State Boards, provide technical assistance and guidance, sponsor research, and organise mass media programmes on pollution prevention. It also monitors water quality through the National Water Quality Monitoring Programme (NWQMP), which covers over 4,000 monitoring stations across India. In addition, the CPCB was subsequently given authority under the Air (Prevention and Control of Pollution) Act, 1981, making it the apex body for both air and water pollution regulation.

State Pollution Control Boards 🔗

Each state has a corresponding SPCB constituted under Section 4, with a chairman appointed by the state government and members representing agriculture, fisheries, industry, and other interests. The State Board plans and executes programmes for the prevention and abatement of water pollution in streams and wells, advises the state government, and enforces compliance by filing cases against violators. It can conduct surveys, gauge flow characteristics of water bodies, inspect industrial premises, take samples, and issue directions to immediately restrain activities causing polluting discharges. The CPCB coordinates with all 29 SPCBs and can step in if a State Board fails to comply with central directions and a grave public emergency arises.

Key provisions of the Water Act in practice 🔗

Several specific sections of the Water Act are practically significant:

Section 17 lays down the powers and functions of SPCBs, including inspection, sampling, and enforcement. Section 24 prohibits disposal of polluting matter into any stream or well. Section 25 requires industries to obtain prior consent before establishing new outlets or discharging new effluents. Section 26 deals with industries that were already discharging effluents before the Act came into force – they must apply for consent within a specified date. If any accident or unforeseen event causes or is likely to cause discharge of poisonous or noxious matter into a stream or well, the person in charge of that place must immediately intimate the State Board. Additionally, the Act establishes state water-testing laboratories to enable scientific analysis of samples collected from streams, wells, and trade effluents.

Landmark case: M.C. Mehta v. Union of India (1987) – the Ganga pollution case 🔗

No discussion of India’s water pollution law is complete without this case. Environmental lawyer M.C. Mehta filed a Public Interest Litigation before the Supreme Court against industries on the banks of the Ganga – particularly tanneries at Jajmau, Kanpur – that were discharging untreated effluents directly into the river. At the time, 274.50 million litres of sewage per day was being discharged into the Ganga from Kanpur alone, with pollution levels recording iron content nearly 100 times the permissible ISI limit.

The Supreme Court, relying on the Water Act, 1974 and the Environment (Protection) Act, 1986, directed the Kanpur Municipal Corporation and tanneries to take immediate action, observing that the Ganga had become so polluted it could no longer be used for drinking or bathing. The Court ordered tanneries to install primary effluent treatment plants and directed the closure of those that failed to comply. It also held that the right to a clean environment is part of the right to life under Article 21 of the Constitution. This case remains a cornerstone of Indian environmental jurisprudence and demonstrates the judiciary’s active role in enforcing water pollution law when executive agencies fall short.

The Water (Prevention and Control of Pollution) Amendment Act, 2024 🔗

Fifty years after the original Act, Parliament introduced the Water (Prevention and Control of Pollution) Amendment Act, 2024, which received Presidential assent on February 15, 2024. The amendment is currently applicable to Himachal Pradesh, Rajasthan, and the Union Territories, with other states able to adopt it through resolutions.

What the 2024 amendment changes 🔗

The most significant shift introduced by the 2024 amendment is decriminalisation of minor offences. Under the original Act, violations could attract imprisonment. The 2024 amendment replaces imprisonment for minor technical and procedural defaults with financial penalties, ranging from ₹10,000 to ₹15 lakh, to reduce the legal burden on businesses and encourage compliance through monetary deterrents rather than criminal charges. The amendment also empowers the Central Government to exempt certain categories of industrial plants from the prior consent requirement. Adjudication of penalties is transferred from Pollution Control Boards to designated adjudicating officers at the rank of Joint Secretary (Central) or Secretary (State). Appeals against their orders lie before the National Green Tribunal, provided 10% of the penalty is deposited upfront.

Controversy around the amendment 🔗

The 2024 amendment has attracted sharp criticism from legal experts and environmentalists. Water expert Himanshu Thakkar argued that India needs decentralisation and stricter laws, but the amendment delivers the opposite – more centralisation of power and weaker penal provisions. Critics in Parliament argued that removing the fear of imprisonment weakens the deterrent against polluting industries. The 2024 changes cap penalties for environmental violations and transfer adjudication powers away from State Boards, which may reduce the boards’ enforcement authority and lessen the deterrent effect on polluting industries. Supporters, however, argue that decriminalisation promotes compliance and aligns the regulatory framework with the “Ease of Doing Business” initiative.

Persistent challenges in water pollution control 🔗

Despite having one of the world’s earliest water pollution laws, India continues to struggle with implementation. The State of the Environment Report 2023 found that 46% of India’s rivers, including the Ganga, are facing significant pollution problems. NITI Aayog estimates that approximately 400,000 deaths occur annually due to contaminated water.

Several structural issues undermine enforcement. Inconsistent board compositions and frequent leadership changes in SPCBs disrupt policy continuity. Funding for Pollution Control Boards has historically been unstable, limiting their technical capacity. Judicial unfamiliarity with environmental science has at times delayed effective adjudication. Public awareness about legal rights and reporting mechanisms remains low in rural and peri-urban areas. The Water Cess Act, 1977 – which levies a cess on water consumed by certain industries to augment CPCB and SPCB resources – was meant to address the funding gap, but experts note that resource constraints persist.

The role of the National Green Tribunal (NGT), established in 2010, has been crucial in filling enforcement gaps. The NGT adjudicates disputes related to environmental violations and has issued directions on industrial discharge, riverbank encroachment, and sewage treatment in several states. However, its reach in rural areas and in matters involving smaller polluters remains limited.

The constitutional dimension: water pollution as a rights issue 🔗

Water pollution is not merely a regulatory matter – it carries constitutional weight. The Supreme Court has consistently held that the right to clean water is part of the fundamental right to life under Article 21 of the Constitution, which guarantees the right to life and personal liberty. Article 48-A, a Directive Principle, directs the State to protect and improve the environment. Article 51-A(g) makes it a fundamental duty of every citizen to protect and improve the natural environment, including rivers and lakes. Together, these provisions create a constitutional imperative to treat water quality as a rights issue, not just an administrative one.

For rural governance, this intersection of law and rights is especially significant. Gram Panchayats, under the 73rd Constitutional Amendment, are empowered to manage natural resources including water bodies at the local level. Yet their capacity to enforce water quality standards and coordinate with SPCBs is often constrained by financial and administrative limitations. Strengthening this interface between local self-governance and the Water Act’s institutional machinery remains one of the most important unresolved challenges in India’s environmental governance architecture.

What do you think? Given that financial penalties under the 2024 Amendment could be seen as a “cost of doing business” for large industries, do you think decriminalisation truly strengthens or weakens the deterrent against water pollution? And should Gram Panchayats be given direct enforcement powers under the Water Act to address pollution at the grassroots level?
