Water Act 1974 — Ecological Framework
Ecological Framework
The Water (Prevention and Control of Pollution) Act 1974 is India's primary legislation for water pollution control, establishing a comprehensive regulatory framework through Central and State Pollution Control Boards.
Based on Article 252 of the Constitution, the Act operates through a two-stage consent mechanism requiring industries to obtain 'Consent to Establish' before setup and 'Consent to Operate' before commencing operations.
The CPCB sets national standards and coordinates policy while SPCBs handle state-level implementation and enforcement. The Act classifies water bodies into five categories (A to E) based on designated uses, from drinking water sources to industrial cooling.
Penalties include imprisonment up to seven years and substantial fines, significantly enhanced by the 1988 amendment. Key provisions include effluent standards, water quality monitoring, and powers to close non-compliant industries.
Landmark Supreme Court cases like MC Mehta and Vellore Citizens have expanded the Act's scope by establishing principles like 'polluter pays' and absolute liability for environmental damage. The Act faces implementation challenges including capacity constraints in SPCBs, industrial resistance, and coordination issues, but remains relevant through integration with recent initiatives like the Jal Shakti Ministry and Namami Gange programme.
From a UPSC perspective, the Act is crucial for understanding India's environmental federalism, the evolution of environmental rights under Article 21, and the practical application of pollution control mechanisms in industrial regulation.
