Groundwater NOC in Karnataka (KGWA): Complete 2026 Guide for Industries

Bengaluru's explosive growth has made groundwater one of Karnataka's most contested resources. To regulate it, the state uses its own law — the Karnataka Ground Water (Regulation and Control of Development and Management) Act, 2011 — administered by the Karnataka Ground Water Authority (KGWA). So if your factory in Peenya or Bommasandra, your campus in Electronic City, or your plant in Mysuru or Hubballi draws groundwater, you apply to KGWA — not to CGWA.

This guide explains who regulates groundwater in Karnataka, who must apply, and the process, documents and compliance for industries and bulk users.

Who Is KGWA and Why Not CGWA?

The Karnataka Ground Water Authority regulates the development and management of groundwater under the 2011 Act, with powers to notify over-exploited areas, register wells and drilling rigs, and require permission for extraction by non-domestic users in regulated zones. Because Karnataka has its own authority and legislation, CGWA does not issue groundwater NOCs in the state. Industrial, commercial and infrastructure users seek permission from KGWA.

Who Needs a KGWA NOC in Karnataka?

• Industries in Peenya, Bommasandra, Jigani, Nelamangala and Electronic City around Bengaluru
• Manufacturing and food-processing units in Mysuru, Hubballi-Dharwad, Belagavi and Tumakuru
• IT/ITeS campuses, data centres and commercial complexes in Bengaluru's tech corridors
• Real-estate, township and infrastructure projects drawing groundwater
• Hotels, hospitals, educational institutions and packaged-water units

Notified & Over-Exploited Areas: Where Rules Bite

KGWA regulation is strongest in notified over-exploited areas, including large parts of the Bengaluru urban and rural districts and other stressed taluks. In these zones, sinking new wells and extracting groundwater for non-domestic use requires permission, drilling rigs must be registered, and recharge measures are expected. A credible hydrogeological assessment is important given Karnataka's hard-rock (granitic-gneiss) terrain, where yields are localised and best confirmed by a resistivity survey.

How to Apply for a KGWA NOC — Step by Step

Step 1 — Apply to the Karnataka Ground Water Authority

Submit your application for groundwater extraction permission (and well registration) to KGWA through the state's antharjala / Ground Water Directorate service, with entity and project details.

Step 2 — Hydrogeological Assessment

Commission a hydrogeological report with a resistivity survey suited to hard-rock terrain, establishing aquifer feasibility and a realistic safe yield for your demand.

Step 3 — Compile Documents and Recharge Plan

Attach KYC, land, pollution-board consent and a rainwater-harvesting / recharge plan along with the technical report.

Step 4 — Authority Scrutiny

KGWA verifies the notified-area status, source protection and aquifer capacity, and may inspect the site.

Step 5 — Grant of Permission

On approval, permission is issued with conditions; renew before expiry and maintain recharge and monitoring obligations.

Documents Required

• Entity KYC — PAN, GST, incorporation / registration and authorisation
• Land ownership / lease documents and site plan with coordinates
• Hydrogeological assessment / feasibility report (with resistivity survey)
• Rainwater harvesting / recharge plan
• Karnataka State Pollution Control Board consent, where applicable
• Details of existing wells and, for drilling, rig registration

Fees, Validity & Compliance

KGWA charges permission and registration fees that vary by user category and demand, with stricter conditions in notified over-exploited areas. Permissions are granted for a defined period and must be renewed before expiry, and users are expected to maintain rainwater harvesting and periodic monitoring. Confirm the current fee schedule with the Karnataka Ground Water Directorate, as rules are revised from time to time.

Karnataka vs the National System

Karnataka's KGWA route is separate from the central Bhu-Neer system — see our Bhu-Neer application guide. Compare with other own-authority states such as Telangana, or read the complete CGWA NOC guide for the national picture.

Frequently Asked Questions

1. Is CGWA NOC applicable in Karnataka?

No. Karnataka regulates groundwater under its own 2011 Act through the Karnataka Ground Water Authority (KGWA). CGWA does not issue groundwater NOCs in the state.

2. Which authority issues groundwater permission in Bengaluru?

The Karnataka Ground Water Authority (KGWA). Bengaluru urban and rural areas are largely notified as over-exploited, so non-domestic extraction requires KGWA permission.

3. Do industries in Peenya and Bommasandra need a KGWA NOC?

Yes. Industrial units drawing groundwater in Peenya, Bommasandra, Jigani and other Bengaluru clusters must obtain KGWA permission in notified areas.

4. Is well and rig registration required in Karnataka?

Yes. The 2011 Act provides for registration of wells and drilling rigs and for permission to extract groundwater by non-domestic users in notified areas.

5. Why is a resistivity survey important in Karnataka?

Karnataka's granitic-gneiss hard-rock terrain has localised, fracture-controlled groundwater, so a resistivity survey is important to justify a realistic yield and support the application.
