CGWA groundwater NOC approval is mandatory for many Indian industries, mines and infrastructure projects. Check exemptions, documents, renewal dates and penalties.

Operating a borewell without the required permission can trigger environmental compensation of at least ₹1 lakh, sealing of the well and a separate statutory penalty. The expensive mistake is assuming that owning the land, holding a pollution consent or using “only a little water” automatically makes groundwater extraction legal.

This guide explains when a Central Ground Water Authority (CGWA) No Objection Certificate applies, how to apply and what non-compliance costs.

Do You Need CGWA Groundwater NOC Approval?

The starting rule is broad. Under the Ministry of Jal Shakti’s Guidelines to Regulate and Control Ground Water Extraction in India, notified through S.O. 3289(E) on 24 September 2020 and amended by S.O. 1509(E) on 29 March 2023, new and existing industries, infrastructure projects and mining projects abstracting groundwater need an NOC unless a stated exemption applies.

“Abstracting” means withdrawing water from below ground through a borewell, tubewell, dug well or similar structure. It does not matter whether the water is used as a raw material, for processing, cooling, washing, construction, landscaping or staff facilities. Dewatering a mine or construction site is also regulated.

The CGWA was constituted under section 3(3) of the Environment (Protection) Act, 1986. It issues directions under section 5 of that Act. But water is also a state subject, so the correct authority depends on the project location.

The CGWB ground-water regulation page says CGWA currently regulates extraction in 20 states and Union Territories; other jurisdictions use a state or designated authority. Annexure VIII of the guideline is dynamic, so confirm the authority for the exact site.

Identify the user category, every existing or proposed well, daily requirement in m³/day or KLD, the latest assessment-unit category and whether CGWA or a state authority regulates the site.

An NOC is separate from Consent to Establish, Consent to Operate, environmental clearance, factory licence and building permission. One approval does not replace another. If your project also needs pollution-board approval, read our environmental clearance process guide.

Which Groundwater NOC Exemptions Apply - and Where Do Owners Get Trapped?

Paragraph 1.0 of the consolidated guidelines exempts these central-framework categories:

An exemption is not a blank cheque. Three checks matter.

First, confirm enterprise classification. The less-than-10 m³/day exemption is for micro and small enterprises, not every business with low withdrawal. Keep the current Udyam record and a defensible water balance.

Second, separate domestic use from operational use. Water used in a production process, washing line, cooling system or commercial activity is not “only” drinking and domestic water. A factory drawing 4 m³/day for workers and another 3 m³/day for processing cannot describe the entire 7 m³/day as domestic.

Third, central exemption does not erase a stricter state law, notified-area restriction, local borewell permission or NOC condition imposed by another regulator. Record the legal basis for the exemption in the compliance file. “Our borewell contractor said it was fine” is not evidence.

Can a New Industry Get an NOC in an Over-Exploited Area?

Location changes the answer. Assessment units are classified by the stage of groundwater extraction: safe, semi-critical, critical or over-exploited. The current category must be checked for the block, taluka, mandal or other assessment unit containing the project.

Under paragraph 4.1 of the central guidelines, a new industry in an over-exploited assessment unit generally cannot receive an NOC, except an enterprise in the micro, small or medium enterprise category. Even that exception does not rescue a new packaged drinking-water industry: the guidelines bar new packaged-water units in over-exploited areas, including MSMEs.

Expansion of an existing industry that increases groundwater abstraction is also not permitted in an over-exploited assessment unit. Existing industries may continue only through the applicable permission framework and must pay groundwater restoration charges.

For a proposed plant, this is a site-selection issue. Before buying land, verify the assessment unit, water intensity, alternate supply, demand and reuse. If an over-exploited classification blocks the project, change the water source, process or site - not the wording of the application.

What Documents Does an Industrial Groundwater NOC Application Need?

The document pack depends on project type and withdrawal quantity. For an industrial application, the consolidated guidelines specifically require:

The impact study is not required at one universal quantity. It becomes mandatory above 100 m³/day in over-exploited, critical and semi-critical areas. In safe assessment units, the threshold is above 500 m³/day for non-alluvial geology and above 2,000 m³/day for alluvial geology. The study must cover a five-kilometre radius and be prepared by an accredited consultant.

Also prepare entity authorisation, site and borewell coordinates, land proof, a source-wise water balance, process-flow diagram, recycling plan, prior NOCs and abstraction records.

Infrastructure dewatering needs an impact assessment and five-kilometre model. Construction in safe or semi-critical areas needs a ₹10 affidavit on non-availability of another source; critical and over-exploited areas require a government certificate that treated sewage water is unavailable within ten kilometres. New projects also need approved building plans or other statutory proof.

Use the project category that matches the real activity. Filing an industrial unit as “infrastructure” or understating withdrawal may create a false-information violation later.

How to Apply for a Groundwater NOC Without Losing Weeks

CGWB directs proponents to the official groundwater NOC application portal. The current CGWB site also identifies the upgraded Bhu-Neer application as the government platform. Avoid private websites that resemble a registration portal.

Use this sequence:

  1. Confirm jurisdiction and category. Record the authority, project type, assessment-unit category and exemption analysis.
  2. Prepare a water balance. Reconcile groundwater, other sources, reuse, losses and discharge in m³/day.
  3. Map every structure. List active, unused, abandoned, proposed and monitoring wells with coordinates and depth.
  4. Collect external evidence. Obtain water-supply letters, laboratory reports and statutory approvals early.
  5. Commission required studies. Use an accredited groundwater consultant, not a generic environmental report.
  6. Submit and preserve evidence. Keep the application number, payment receipt and every response.
  7. Answer scrutiny consistently. Correct conflicting quantities across the form, water balance and reports.
  8. Wait for legal permission. An acknowledgement is not an NOC.

Application and renewal fees are charged at rates prescribed by CGWA and displayed through the official portal. The consolidated guideline deliberately does not freeze one amount. Ignore old articles quoting ₹1,000 for every fresh application; verify the portal-generated amount for your case.

What Must You Do After the NOC Is Issued?

The certificate creates recurring work. Typical conditions include installing a digital water-flow meter with telemetry, recording daily withdrawal, submitting abstraction and groundwater-level data, constructing monitoring wells where required, maintaining rainwater-harvesting structures and filing self-compliance reports.

Industrial users above 100 m³/day must conduct a water audit once every two years through a certified auditor approved by CGWA and submit the report within three months of completion. The guideline also requires these industries to reduce groundwater use by at least 20% over the next three years through suitable measures.

Outside designated industrial areas, an observation well or piezometer is mandatory for industries or infrastructure projects drawing more than 100 m³/day from hard-rock aquifers or more than 500 m³/day from alluvial aquifers. Monthly water-level data must go to CGWA through the portal.

Create one register covering the NOC and permitted quantity, every well, daily readings, telemetry, reports, recharge evidence, payments, expiry date and renewal owner.

This is where Compliance Radar should earn its keep: the NOC, pollution consent, factory licence and environmental filings belong on one timeline, not in four inboxes.

When Must a Groundwater NOC Be Renewed?

Section 11 of the consolidated guideline requires the renewal application at least 90 days before expiry, accompanied by a compliance report. For renewals, industries in safe, semi-critical and critical units receive a three-year term; mines receive two years; infrastructure projects for drinking or domestic use and urban water-supply agencies receive five years. All users in over-exploited areas receive a two-year renewal term.

If a complete renewal is filed on time but the authority cannot process it before expiry, the NOC is deemed extended until the renewal decision. If the proponent fails to apply within three months after expiry, environmental compensation becomes payable from the expiry date until renewal.

Do not treat deemed extension as permission to ignore conditions. Preserve the timely filing acknowledgement and continue every monitoring, payment and reporting obligation.

What Are the Penalties for Illegal Extraction or NOC Breaches?

Section 15 of the CGWA guideline calculates environmental compensation for illegal groundwater extraction by project type, area category, withdrawal and duration. For industrial units, the rate ranges from ₹20 per m³ in the lowest listed safe-area band to ₹200 per m³ in the highest listed over-exploited-area band. The minimum environmental compensation is ₹1 lakh.

Table 16.1 adds fixed penalties for breaching NOC conditions. Examples include:

Non-compliance | Guideline penalty

Missing or faulty digital flow meter with telemetry | ₹2,00,000

Undisclosed functional or non-functional abstraction structure | ₹2,00,000 per structure

Missing piezometer | ₹2,00,000

Missing or faulty digital water-level recorder/telemetry | ₹1,00,000

Missing or inadequate recharge or water-conservation structure | ₹5,00,000

Injecting treated or untreated wastewater into an aquifer | ₹10,00,000 plus remediation cost

Failure to submit water-level or water-quality data | ₹50,000

Failure to maintain a daily log or submit abstraction data | ₹50,000

Failure to submit a self-compliance report | ₹1,00,000

False information or undertaking | ₹1,00,000

The response is not limited to money. Authorised district officers may seal an illegal well, disconnect its electricity supply and initiate enforcement. A breach can also cause NOC cancellation or refusal of renewal.

The current Environment (Protection) Act, 1986 changed from 1 April 2024. Section 15 provides ₹10,000 to ₹15 lakh for a contravention without another specified penalty, plus ₹10,000 for each continuing day. For a company, section 15A provides ₹1 lakh to ₹15 lakh per contravention and an additional ₹1 lakh for each continuing day. These statutory penalties can sit alongside environmental compensation and NGT relief.

If you receive a notice, preserve meter data, borewell details, invoices and correspondence; calculate the extraction period; answer every allegation; and obtain environmental legal and hydrogeological advice. See our pollution-board notice response guide.

A 10-Point Groundwater Compliance Checklist

Frequently Asked Questions About CGWA Groundwater NOC Approval

Does every factory borewell need a CGWA NOC?

Most industrial extraction requires an NOC from CGWA or the competent state authority. A specific exemption may apply, such as a micro or small enterprise drawing less than 10 m³/day, but the business must prove the classification, quantity and applicable jurisdiction.

Is an MSME automatically exempt from groundwater permission?

No. The central exemption covers micro and small enterprises below 10 m³/day, not every MSME at every quantity. Medium enterprises are not included in that exemption. State requirements and special restrictions may still apply.

Is Consent to Operate from the pollution board enough?

No. Pollution-board consent and groundwater permission regulate different risks. The CGWA application may use Consent to Establish or environmental clearance as supporting evidence, but those documents do not replace the groundwater NOC.

How early should I renew a groundwater NOC?

Apply at least 90 days before expiry with the compliance report. Operationally, start the audit at 180 days so missing telemetry data, recharge work or unpaid charges can be corrected before filing.

Can a new packaged-water unit open in an over-exploited area?

Under the central guideline, no new packaged drinking-water industry may receive an NOC in an over-exploited assessment unit, even if it is an MSME. Verify the current site category before committing capital.

Make the NOC a Live Compliance Calendar

CGWA groundwater NOC approval is not complete when the PDF arrives. The actual obligation is a chain: lawful siting, accurate water balance, full well disclosure, metering, telemetry, recharge, reporting, charges and renewal.

One missed report can cost ₹50,000. One missing recharge structure can cost ₹5 lakh. An undisclosed borewell can cost ₹2 lakh before environmental compensation and statutory exposure are counted.
