Bihar CGWA NOC Status (2024)
District-wise Ground Water Assessment & How to Apply Online
Urgent Compliance Alert for Businesses in Bihar
If your industry, commercial establishment, or institution in Bihar uses a borewell or extracts groundwater, obtaining a valid CGWA NOC (No Objection Certificate) is MANDATORY under Central Ground Water Authority regulations.
Non-compliance in Bihar’s increasingly regulated districts (like Patna Urban, Giriyak, Mushahari, etc.) can result in heavy penalties, borewell sealing, or immediate business shutdown under the Environment Protection Act.
Why CGWA NOC is Essential in Bihar
Legal Requirement:
Every unit using groundwater must have valid CGWA permission.
Avoid Penalties:
Non-compliance attracts heavy fines and closure, especially in Critical/Over-Exploited Zones.
Sustain Water Use:
NOC ensures sustainable extraction in Semi-Critical and Over-Exploited regions.
Essential for Business:
Required for Pollution NOC, Factory License, Bank Loans, and Project Approvals.

🧠 Frequently Asked Questions on Bihar CGWA NOC
1. Is CGWA NOC mandatory for all industries in Bihar?
Yes. All industries, commercial units, and institutions extracting groundwater must obtain CGWA permission. Even units in ‘Safe’ category districts require borewell registration and a water conservation plan.

Patna Urban falls under the Over-Exploited category. Applications in this zone are highly scrutinized and generally restricted. You must have a robust conservation plan and seek expert help immediately to manage the application process.
3. How is my district’s status (Critical/Safe) determined?
The status (Safe, Semi-Critical, Critical, or Over-Exploited) is determined by the Central Ground Water Authority (CGWA) through scientific assessment of long-term water level decline and stage of groundwater extraction, as per the latest Bihar assessment data.
