Groundwater NOC

In Tamil Nadu, obtaining a No Objection Certificate (NOC) for groundwater extraction is mandatory for industries, commercial establishments, and infrastructure projects that require groundwater for their operations. The regulation is enforced by the Tamil Nadu Water Resources Department and the Central Ground Water Authority (CGWA) to ensure sustainable groundwater management and prevent over-extraction.

Who Needs a Groundwater NOC?

1. Industries – Factories and manufacturing units using groundwater for production, cooling, or other processes.
2. Commercial Establishments – Hotels, malls, hospitals, and office complexes relying on borewells.
3. Infrastructure Projects – Construction companies and real estate projects using groundwater.
4. Agricultural Users – Large-scale farms (if using mechanized borewells).

Process for Obtaining Groundwater NOC

1. Application Submission
  • The applicant must apply online via the Tamil Nadu Water Resources Department or CGWA portal.
  • Submit details of land, borewell specifications, water usage, and recharge measures.
2. Hydrogeological Study & Site Inspection
  • The groundwater level and availability in the region are assessed.
  • If located in an over-exploited area, strict conditions may apply, or NOC may bedenied.
3. Installation of Water Flow Meters & Recharge Structures
  • Industries must install digital water meters to monitor extraction.
  • Rainwater harvesting or artificial recharge structures are often required forapproval.
4. Approval & Periodic Renewal
  • Once verified, the Groundwater NOC is issued with a validity period (usually 3–5 years).
  • Renewal is required before expiry, ensuring compliance with water conservation rules.

Key Regulations & Compliance
