Introduction

• The official name is the Water (Prevention and Control of Pollution) Act, 1974. It is one of India’s earliest major environmental laws dealing specifically with water pollution. It is Act No. 6 of 1974 and its long title states that it was enacted to prevent and control water pollution and to maintain or restore the wholesomeness of water.
• The Act was enacted on 23 March 1974.
• The Act was enacted to:
  • prevent and control water pollution
  • maintain or restore the wholesomeness of water
  • establish Boards for carrying out these purposes
  • confer powers and functions on those Boards.
• The Water Act is important because it created India’s core legal framework for controlling pollution in rivers, streams, wells, inland waters, and related water bodies. It also laid the institutional base for pollution-control governance through national and state-level boards.

Constitutional background

• The Act has a special constitutional background. Its text records that Parliament did not otherwise have full power to legislate on this state subject except as provided under Articles 249 and 250, and therefore the law was enacted on the basis of resolutions by States under the constitutional mechanism then used for this subject.

Institutional framework

• A major feature of the Act is the creation of:
  • the Central Pollution Control Board (CPCB)
  • State Pollution Control Boards (SPCBs)
  • and, where relevant, Joint Boards.

Central Pollution Control Board

• Under the Act, the Central Board was established to perform national-level functions relating to water pollution control. CPCB-linked material continues to identify the Water Act, 1974 as the legal basis for its water-pollution role.

State Pollution Control Boards

• The Act also provides for State Pollution Control Boards, which are the principal authorities at the state level for implementing the law, granting consents, monitoring pollution, and taking enforcement steps.

Main functions of the Boards

• The Boards under the Act are empowered to perform functions relating to:
  • planning pollution prevention and control programmes
  • advising governments
  • collecting and disseminating technical information
  • monitoring water quality
  • setting standards and enforcing compliance.

Scope of the Act

• The Act is structured into chapters dealing with:
  • preliminary provisions
  • Central and State Boards
  • Joint Boards
  • powers and functions of Boards
  • prevention and control of water pollution
  • funds, accounts and audit
  • penalties and procedure.

Consent mechanism

• One of the most important operational features of the Act is the consent mechanism. Industries and other operations that discharge sewage or trade effluent into streams, wells, sewers, or on land generally require prior consent from the relevant Pollution Control Board. This is the basis of the well-known CTE/CTO framework in pollution regulation.

Prohibition on polluting discharges

• The Act contains a core prohibition against knowingly allowing poisonous, noxious, or polluting matter to enter streams or wells beyond permitted limits. This makes the law a direct anti-pollution statute, not merely an administrative licensing law.

Powers of inspection and sampling

• The Boards have powers relating to:
  • entry and inspection
  • taking samples of effluents
  • obtaining information
  • monitoring compliance.

Standards and regulation

• The Water Act allows Boards to regulate water pollution by prescribing and enforcing standards for sewage and trade effluents and by examining industrial discharges affecting water bodies.

Penalties

• The Act contains a dedicated chapter on penalties and procedure, which means violations can attract criminal consequences and prosecution. This gives the law an enforcement dimension beyond routine regulatory oversight.

Link with water quality monitoring

• CPCB material connects the Water Act to regular water quality monitoring and surveillance, showing that the statute supports not only enforcement but also systematic monitoring of the condition of water resources.

Relationship with later environmental law

• The Water Act is one of India’s earliest major pollution-control laws and became a foundation for later environmental regulation, including the broader framework of CPCB/SPCB governance that was later supplemented by the Air (Prevention and Control of Pollution) Act and the Environment (Protection) Act, 1986. The India Code structure and CPCB descriptions place the Water Act in this foundational role.

Conclusion

• The Water Act, 1974 is a foundational environmental law in India. Its significance lies in creating the legal and institutional structure for preventing and controlling water pollution through Boards, consent requirements, monitoring, standards, and penalties.
