Questions

Frequently Asked Questions (FAQs)

What is the Water (Prevention and Control of Pollution) Act, 1974?
The Water Act, 1974 is an Indian environmental law designed to prevent and control water pollution and maintain or restore the wholesomeness of water. It establishes Pollution Control Boards and provides mechanisms for regulating sewage and trade effluent.
Why is the Water Act important for industries?
The Act is important because industries that generate sewage or trade effluent may have to comply with consent, wastewater treatment, discharge, monitoring and other pollution-control requirements.
What is the difference between CTE and CTO?
Consent to Establish (CTE) generally relates to establishing a project, while Consent to Operate (CTO) relates to operating the established unit subject to applicable conditions.
What happens if an industry violates the Water Act?
Depending on the nature of the violation, regulatory authorities may take corrective or enforcement action, including directions, restrictions, penalties or prosecution under applicable provisions.
Does the Water Act require industries to operate an ETP?
Where an industrial process generates wastewater requiring treatment, an appropriate wastewater-treatment system may be required based on the industry's activity, discharge characteristics, consent conditions and applicable environmental standards.
