Setting up an RO (Reverse Osmosis) Water Plant in India is a promising venture — whether you aim to provide packaged drinking water, process water for industries, or purification services for commercial facilities.
However, beyond the technical setup, navigating the government approval process is critical. Proper licenses ensure legal compliance, public safety, and smooth operations.
Why Government Approvals Are Crucial
This guide breaks down all essential government certifications, licensing requirements, and pro tips to help you launch your RO plant without delays.
Government approvals are necessary to:
- Ensure water safety and quality as per BIS and FSSAI standards
- Comply with environmental norms and local regulations
- Avoid shutdowns, legal penalties, or brand credibility issues
- Build consumer trust with verified certifications
Operating without proper licenses can lead to prosecution under BIS, FSSAI, and Environmental Acts.
