Water (Prevention and Control of Pollution) Act, 1974

Water (Prevention and Control of Pollution) Act, 1974 is India’s first comprehensive statute dedicated to safeguarding the nation’s water bodies from degradation. Enacted on 12 December 1974, the Act created a dual‑tier regulatory architecture—central and state pollution control boards—and gave them sweeping authority to set discharge standards, issue consents, and enforce remedial action. Its uniqueness lies in codifying “pollution” as any alteration of water quality that endangers its suitability for drinking, irrigation, industrial use, or aquatic life, thereby providing a legal definition that underpins all subsequent water‑environment legislation. ## Origins and Legislative Context The Act emerged against a backdrop of escalating industrial effluent discharges into the Ganga, Yamuna, and other rivers during the early 1970s. The 1972 United Nations Conference on the Human Environment in Stockholm spurred Indian policymakers to adopt a dedicated water‑pollution framework, complementing the earlier Water (Prevention and Control of Pollution) Act draft of 1973. Parliament passed the legislation on 12 December 1974, and it received presidential assent on 30 December 1974. The same year, the Central Pollution Control Board (CPCB) was constituted under Section 4 of the Act, reporting to the Ministry of Environment, Forest and Climate Change. By 1977, every state had established a State Pollution Control Board (SPCB) as mandated by Section 5, laying the institutional foundation for coordinated water‑quality governance across the federation. ## How the Mechanism Operates Section 4 empowers the CPCB and SPCBs to prescribe effluent standards for specific industries, expressed in milligrams per litre of biochemical oxygen demand (BOD), total suspended solids (TSS), and heavy‑metal concentrations. Section 5 requires any industrial unit to obtain a Consent to Establish before construction and a Consent to Operate before discharge, both of which can be revoked if standards are breached. Section 6 authorises the boards to prohibit or restrict any discharge that threatens a water body’s designated use, while Section 7 mandates remedial measures such as installation of effluent‑treatment plants. Inspection powers reside in Section 9, allowing officers to enter premises, take samples (Section 10), and issue directions (Section 11) for immediate compliance. Violations attract penalties ranging from ₹1,000 to ₹1,00,000 per day of default under Section 12, with higher fines for corporations under Section 13. Appeals are heard by the State Pollution Control Appellate Tribunal as per Section 14. ## Key Provisions at a Glance - Section 3: Definition of “water” (rivers, lakes, streams, groundwater) and “pollution.” - Section 4: Power to set national and state water‑quality standards; CPCB publishes the National Water Quality Standards (NWQS) for 22 parameters. - Section 5: Mandatory consent regime for establishment and operation of polluting units. - Section 6–8: Authority to prohibit, regulate, or close polluting sources; includes emergency shutdown powers. - Section 9–11: Inspection, sampling, and direction‑issuing mechanisms; officers may seize samples without a warrant. - Section 12–13: Penalties and cognizance provisions; offences are cognizable and non‑bailable. - Section 15: Provision for public participation through citizen‑suit provisions, allowing NGOs to file complaints with SPCBs. ## India’s Implementation Trajectory Since 1974, the CPCB has expanded its monitoring network to ≈ 5,000 sampling stations under the National Water Quality Monitoring Programme (NWQMP). As of 2023, 33 SPCBs operate, each publishing annual State Water Quality Index reports. The Act’s amendment in 1981 introduced stricter penalties and broadened the definition of “pollutant” to include thermal and radioactive discharges. Despite these advances, compliance gaps persist: the Central Pollution Control Board’s 2022 report flagged that ≈ 70 % of industrial units in the National Capital Region exceeded BOD limits, and municipal sewage treatment coverage remains below 45 % nationally. Recent National Green Tribunal (NGT) orders—such as the 2024 directive to Balaghat district authorities to remediate illegal waste dumping—illustrate the Act’s continued relevance in judicial enforcement. ## International Comparison The Water (Prevention and Control of Pollution) Act predates the United States’ Clean Water Act (1972) but shares its core principle of a permit‑based discharge system. Unlike the EU Water Framework Directive (2000), which adopts a river‑basin management approach, the Indian Act focuses on point‑source regulation and leaves non‑point source control largely to state‑level initiatives. Nonetheless, the Act’s structure—central standards, state implementation, and citizen‑suit provisions—mirrors the global trend toward co‑operative federalism in water governance. ## Significance and Legacy By institutionalising a legal framework
