1. Conceptual Framework & Statutory Objectives

• Pioneering Environmental Statute: The Water (Prevention and Control of Pollution) Act, 1974 was enacted to establish a dedicated legal framework for preserving water quality and controlling water pollution across India.
• Core Objective: The primary statutory mandate of the Act is the prevention, control, and abatement of water pollution and the maintenance or restoration of the wholesomeness of water in streams, rivers, lakes, wells, sewers, or on land.
• Institutional Creation: The Act established the statutory two-tier system of Pollution Control Boards at the Central and State levels to monitor water pollution and enforce environmental standards.

2. Institutional Machinery: CPCB and SPCBs

TWO-TIER INSTITUTIONAL STRUCTURE UNDER WATER ACT, 1974

Central Pollution Control Board (CPCB) [Statutory Apex Technical Body]
  ├─► Constituted in September 1974 under Section 3 of the Water Act
  ├─► Advises Central Government on water pollution prevention & river cleanliness
  ├─► Coordinates SPCB activities, provides technical guidance & resolves inter-state disputes
  └─► Lays down effluent disposal standards & ambient water quality guidelines
                           │
                           ▼
State Pollution Control Boards (SPCBs) [State Enforcement Arm]
  ├─► Advises State Governments on water pollution control & industrial siting
  ├─► Inspects sewage/trade Effluent Treatment Plants (ETPs) & disposal systems
  ├─► Grants, refuses, or cancels Consent to Establish (CTE) & Consent to Operate (CTO)
  └─► Prescribes location-specific effluent discharge standards

A. Central Pollution Control Board (CPCB) Functions

• Establishment: Constituted in September 1974 under the Water Act, 1974 as a statutory organization under MoEFCC.
• Mandate: Functions as the apex technical body advising the Centre, coordinating SPCB activities, resolving inter-state disputes, providing technical assistance, and laying down waste disposal standards.

B. State Pollution Control Boards (SPCBs) Functions

• Regional Surveillance: Plans state-level pollution abatement programs, advises State Governments on industrial siting, and collects/disseminates technical data.
• Plant Inspections: Inspects industrial manufacturing units, trade effluent treatment plants (ETPs), and disposal systems to ensure compliance with prescribed discharge limits.

3. Core Regulatory Mechanism: The Consent Regime

• Prohibition on Polluting Discharge: Direct or indirect discharge of poisonous, noxious, or polluting matter into streams, wells, sewers, or land exceeding SPCB standards is strictly illegal.
• Two-Stage Statutory Permit System:
  1. Consent to Establish (CTE): Mandatory prior approval required from the SPCB before constructing or setting up any industrial plant or treatment system likely to discharge sewage or trade effluent.
  2. Consent to Operate (CTO): Mandatory permit required after installing treatment infrastructure and prior to commencing industrial production or discharging effluent.
• Continuous Monitoring: Industries categorized under highly polluting sectors must install Online Continuous Emissions/Effluents Monitoring Systems (OCEMS) connected to CPCB and SPCB portals.

4. Major Legislative Reforms: Water (Amendment) Act, 2024

The Water (Prevention and Control of Pollution) Amendment Act, 2024 introduced significant structural updates to the 1974 framework to promote ease of doing business while retaining environmental deterrence:

KEY STRUCTURAL SHIFTS IN THE 2024 AMENDMENT

Original Water Act, 1974 Framework                Water Amendment Act, 2024 Framework
• Criminal prosecution in magistrate courts        • Administrative monetary penalties (₹10,000 to ₹15 lakh)
• Imprisonment from 1.5 to 6 years + fines         • Adjudicating Officers (Joint/State Secretary rank)
• Mandatory SPCB consent for ALL industries        • Central exemptions for "White Category" units
• State-nominated SPCB Chairpersons               • Central Govt prescribes nomination/service rules
                                                   • Imprisonment retained for operating without
                                                     consent or non-payment of penalties

A. Key Provisions of the 2024 Amendment

1. Decriminalization of Minor Offences: Replaced criminal court prosecution and jail terms for minor, technical, or procedural defaults with administrative financial penalties ranging from ₹10,000 to ₹15 lakh.
2. Adjudicating Officers: Senior officers (minimum Joint Secretary rank at the Centre or Secretary rank in the State) conduct inquiries and assess penalties following natural justice principles.
3. Appeals Route & Fund Allocation: Appeals against penalty orders lie before the National Green Tribunal (NGT) within 60 days (subject to a mandatory 10% pre-deposit). Collected penalties are credited to the Environmental Protection Fund.
4. Consent Exemptions for Non-Polluting Units: Empowers the Central Government, in consultation with CPCB, to exempt specific industrial categories (such as non-polluting White Category industries like solar PV assembly, air conditioner assembly, and fly-ash brick units) from obtaining prior consent.
5. Standardized SPCB Leadership Rules: Empowers the Central Government to prescribe rules for the nomination procedure, qualifications, and service conditions of SPCB Chairpersons.
6. Retention of Imprisonment: Criminal imprisonment remains in force for operating an industry without valid SPCB consent under Section 25/26 (imprisonment up to 6 years) or failing to pay imposed penalties within 90 days (imprisonment up to 3 years).
7. Adoption Mechanism: Applied to Union Territories and adopting states (such as Punjab, Bihar, West Bengal, and Manipur) via state assembly or parliamentary resolutions.

5. The Water (Prevention and Control of Pollution) Cess Act, 1977

• Statutory Purpose: Enacted in 1977 (enforced April 1, 1978) to levy a cess on water consumed by specified industrial activities and local authorities (municipal corporations, water supply boards).
• Resource Augmentation: Revenue collected is utilized to augment the financial resources of CPCB and SPCBs for enforcing pollution control programs.
• 70% Cess Rebate Incentive: Grants a 70% rebate on the applicable water cess to any entity that installs and operates an approved Effluent Treatment Plant (ETP) complying with discharge standards.

6. Landmark Judicial Decisions & Constitutional Doctrines

• Right to Clean Water (Subhash Kumar v. State of Bihar, 1991): The Supreme Court ruled that the Right to Life under Article 21 includes the right to enjoy pollution-free water and air.
• State Duty on Clean Drinking Water (A.P. Pollution Control Board II v. Prof. M.V. Nayudu, 2000): Reaffirmed that the state has a constitutional duty to provide safe drinking water to its citizens.
• Mandatory Effluent Treatment Plants (Paryavaran Suraksha Samiti v. Union of India, 2017): The Supreme Court ruled that no industrial unit requiring a Consent to Operate (CTO) can run without a functional Primary Effluent Treatment Plant (PETP) in place.
