CGWA Groundwater Rules (RULE_CGWA)

Reference only — not legal advice. This page is EarthReheal WasteLedger's plain-language interpretation of the rule, written to help organisations understand what may apply to them. It can be incomplete or inaccurate. Always read the official gazette notification or statute, and confirm with your regulator or a qualified adviser, before relying on it for compliance decisions.

Quick Summary

Any organisation in India that draws groundwater above modest thresholds — via borewell, tubewell, or dug well — needs a No Objection Certificate (NOC) from the Central Ground Water Authority (CGWA) or the equivalent state authority before extraction. The rule is enforced not through a single Act but through periodically-reissued CGWA "Guidelines," currently the Guidelines to Regulate and Control Groundwater Extraction, 2020 as amended in 2023, issued under the Environment (Protection) Act, 1986. Non-compliance carries Environmental Compensation, borewell sealing, and disconnection of electricity supply — enforced at the district level by District Magistrates/Collectors acting as CGWA's Authorised Officers.

What This Rule Is

Legal architecture — guidelines, not a standalone statute. CGWA does not operate under its own Act of Parliament. It was constituted on 14 January 1997 (notification S.O. 38(E)) to exercise powers delegated under Section 5 (and sub-section (3) of Section 3) of the Environment (Protection) Act, 1986 for the regulation and control of groundwater management and development, pursuant to the Supreme Court's directions in M.C. Mehta v. Union of India (order dated 10 December 1996, Civil Writ Petition No. 4677 of 1985). Because CGWA's authority flows from a delegated executive notification rather than dedicated legislation, its substantive rules take the form of "Guidelines" that CGWA reissues and amends from time to time — there is no single, permanently fixed "CGWA Act."

Regulatory history. CGWA's first NOC guidelines date to the late 1990s/2000s and were revised repeatedly amid litigation. The National Green Tribunal (NGT) drove much of the current framework: orders in OA Nos. 204/205/206 of 2014 (15 April 2015) directed CGWA to require permission for all tube-well operation; OA Nos. 34 and 37 of 2014 (9 July 2015) brought CETP-member industries into the NOC net; and a series of further orders through 2018–2020 pushed CGWA to tighten monitoring and compensation. An interim set of guidelines (S.O. 6140(E), dated 12 December 2018) was stayed by the NGT on 3 January 2019 as unsustainable under the Precautionary Principle and Article 21. A court-appointed committee then produced the guidelines that were finally notified as:

• S.O. 3289(E), dated 24 September 2020 — "Guidelines to regulate and control ground water extraction in India," issued by the Ministry of Jal Shakti, Department of Water Resources, River Development & Ganga Rejuvenation (Central Ground Water Authority). This superseded the 2018 notification and remains the core operative document.
• Amendment dated 29 March 2023 (Notification No. S.O. 1509(E) — confirm the gazette copy on egazette.gov.in). The amendment added two new NOC exemptions to Paragraph 1.0: (a) industries/mining/infrastructure projects drawing groundwater only for drinking/domestic purposes up to 5 m³/day in all assessment units, and (b) a blanket exemption for Residential Apartments and Group Housing Societies as a category (see "Who This Applies To" below for how this interacts with the pre-existing 20 m³/day STP threshold). It also tightened commercial water-audit reporting and formally folded in the separately-issued Bulk Water Supplier guidelines.
• Guidelines for Bulk Water Suppliers (Office of NOC (CGWA), ref. 18509/2021/O/o NOC(CGWA)) — a companion document specifically for tanker-based water suppliers, issued after the 45th CGWA Board meeting (21 January 2021), which the 2020/2023 guidelines had promised "separately."
• Bhu-Neer portal launch, 19 September 2024 — a digital-platform migration (from the legacy NOC Application Portal, "NOCAP," to the new "Bhu-Neer" portal at cgwa-bhuneer.mowr.gov.in), announced by the Ministry of Jal Shakti during India Water Week 2024. This is a procedural/IT change, not a change to the substantive guidelines text.
• No further gazette amendment to the substantive guidelines was found as of August 2026 beyond the March 2023 amendment. Compliance-vendor sites reference "2025-26" and "2026" compliance guides, but these appear to describe the 2020+2023 guidelines as administered through Bhu-Neer, not a new notified amendment. Confirm any claimed 2024–2026 substantive amendment against egazette.gov.in / CGWA.

Underlying authority. Environment (Protection) Act, 1986 (Section 3(3) and Section 5) — CGWA has no independent statutory charter of its own; it is a creature of this Act's delegation powers, operating under the Ministry of Jal Shakti.

Policy purpose. India's groundwater crisis: roughly 17% of assessed groundwater "assessment units" nationally are categorised Over-Exploited, Critical, or Semi-Critical (based on periodic joint CGWB/State assessments), driven by unregulated agricultural, industrial, and urban extraction. The guidelines aim to (a) require water-supply-agency-first sourcing before groundwater, (b) meter and monitor extraction, (c) charge abstraction/restoration fees scaled to area stress category, and (d) mandate recharge (rooftop rainwater harvesting) as an offsetting condition.

Who This Applies To

NOC is required for: new and existing industries, industries seeking expansion, mining projects, infrastructure projects (see indicative list below), residential apartments/group housing societies drawing above the domestic-use threshold, government water-supply agencies, and — since the Bulk Water Supplier guidelines — private tanker operators selling groundwater.

Exemptions from NOC (Paragraph 1.0, as amended 2023):

1. Individual domestic consumers, rural and urban, for drinking/domestic use.
2. Rural drinking water supply schemes.
3. Armed Forces and Central Armed Police Forces establishments (rural and urban).
4. Agricultural activities (irrigation) — the entire agriculture sector is exempted from NOC as a matter of policy (Para 3.0), on the reasoning that ~88% of agricultural wells are owned by marginal/small/semi-medium farmers and command-and-control regulation is impractical; states are instead urged toward participatory measures (metered/priced electricity, crop diversification).
5. Micro and Small Enterprises (MSE) drawing groundwater less than 10 m³/day. This is the threshold referenced in EarthReheal WasteLedger's earlier citation, and it is confirmed verbatim in the original 2020 Gazette text (Para 1.0(v)): "Micro and small Enterprises drawing ground water less than 10 cum/day." Note this is Micro and Small only — Medium enterprises are not exempted by this clause, though MSMEs as a category retain preferential (not exempt) treatment elsewhere, e.g. they may still receive NOCs in Over-Exploited areas where new "major" industries cannot (Para 4.1).
6. Industries/mining/infrastructure projects drawing groundwater only for drinking/domestic purposes up to 5 m³/day, added by the 2023 amendment, applicable in all assessment-unit categories.
7. Residential Apartments and Group Housing Societies, added as a blanket exemption category by the 2023 amendment. The original 2020 text (Para 2.0) treated residential apartments/group housing societies as NOC-required (subject to a 20 m³/day STP-installation trigger and a five-year NOC validity). The 2023 amendment's exact scope — whether it exempts all such societies outright, or only below some quantum — is described inconsistently across secondary sources; some cite a "20 m³/day with mandatory rainwater harvesting" cutoff. Confirm the precise post-2023 threshold, if any, against the official amendment notification. Until then, treat residential apartments/group housing societies as potentially exempt but confirm the applicable threshold case by case, or default to the more conservative pre-amendment position (NOC required, with the 20 m³/day STP trigger).

Assessment-unit categorisation and how it changes the process. Every block/mandal/taluk in India is periodically assessed jointly by CGWB and State ground water organisations and categorised Safe, Semi-Critical, Critical, or Over-Exploited based on the ratio of groundwater extraction to recharge. This categorisation drives materially different outcomes:

• In Over-Exploited units, no NOC is granted to new "major" industries (MSMEs and packaged-drinking-water units are further restricted even within the MSME carve-out — no new packaged water units are allowed even as MSMEs), and existing-industry expansion involving increased groundwater draw is barred.
• Mining and infrastructure projects are location-specific and are not banned in Over-Exploited units, but pay a steeper "restoration charge" instead of the standard "abstraction charge."
• Abstraction/restoration charge rates (per m³) escalate sharply from Safe → Semi-Critical → Critical → Over-Exploited (e.g., for general industries/infrastructure: ₹1–5/m³ in Safe rising to ₹6–20/m³ restoration charge in Over-Exploited, scaled further by daily withdrawal volume).
• Environmental Compensation rates for illegal extraction are likewise categorised and escalate the same way (e.g., industrial units: ₹20/m³ in Safe areas up to ₹200/m³ in Over-Exploited areas, subject to a minimum EC of ₹1,00,000).
• Projects over 100 m³/day in Over-Exploited/Critical/Semi-Critical units must additionally submit a formal Impact Assessment Report by an accredited consultant.

Waiver/relaxation process: there is no general discretionary waiver beyond the exemptions above. A 50% rebate on abstraction/restoration charges is available to entities that have installed/constructed compliant artificial recharge structures, subject to verified satisfactory performance.

State-Level Variations

CGWA's guidelines apply directly only in the 22 States and 2 Union Territories where groundwater is not independently regulated by a state authority (per Annexure VIII of the 2020 notification): Andaman & Nicobar Islands, Assam, Arunachal Pradesh, Bihar, Chhattisgarh, Dadra & Nagar Haveli and Daman & Diu, Gujarat, Haryana, Jharkhand, Madhya Pradesh, Maharashtra, Manipur, Meghalaya, Mizoram, Nagaland, Odisha, Punjab, Rajasthan, Sikkim, Tripura, Uttar Pradesh, Uttarakhand, and (mining projects only) Andhra Pradesh and Telangana.

Per CGWA's own current state-authority listing, a materially overlapping but not identical set of states/UTs now run their own groundwater regulator/portal rather than routing through CGWA, including: Andhra Pradesh, Goa, Himachal Pradesh, Jammu & Kashmir, Karnataka (Karnataka Ground Water Authority — kgwasakala.karnataka.gov.in), Kerala, Puducherry, Telangana, and West Bengal (dedicated State Ground Water Authorities), plus NCT Delhi, Tamil Nadu, Chandigarh, Lakshadweep, Punjab (Punjab Water Regulation and Development Authority — pwrda.org), Uttar Pradesh (upgwdonline.in), and Haryana (Haryana Water Resources Authority — hwra.org.in), which regulate via government orders/bye-laws rather than a CGWA-style guideline. Because Haryana, Punjab, and Uttar Pradesh appear in both CGWA's Annexure VIII list (as of the 2020 notification) and the more recent "has its own authority" list, the practical position has clearly shifted since 2020 for at least these three states — verify the current regulator for any specific state/UT before advising an org, since state-level authority stand-ups have been an active, moving area since 2020.

Interaction rule (from the 2020 guidelines' Preamble): where a State/UT has its own groundwater guidelines that are inconsistent with CGWA's, CGWA's guidelines prevail; where the state's guidelines are more stringent, the additional state provisions apply on top of CGWA's. States may propose additional conditions based on local hydrogeology, subject to review by CGWA/Ministry of Jal Shakti. In practice, for an organisation in a state with its own dedicated authority (e.g., Karnataka, West Bengal), CGWA's central Bhu-Neer/NOCAP process is not the applicable route at all — the state authority's own NOC process governs.

Compliance Requirements — What You Actually Have to Do

NOC application process and portal. The entire NOC process is mandated to be online. The legacy system was the NOC Application Portal ("NOCAP") — referenced throughout the 2020 gazette text and as recently as the 2021 Bulk Water Supplier guidelines. This was superseded by the "Bhu-Neer" portal, launched 19 September 2024 by the Ministry of Jal Shakti (developed with the National Informatics Centre), at cgwa-bhuneer.mowr.gov.in. Bhu-Neer introduced a PAN-based unified user ID, QR-coded NOCs, and a centralised compliance database; NOCs issued under the old NOCAP system reportedly require a data-migration step before renewal can be filed on Bhu-Neer. Confirm cgwa-bhuneer.mowr.gov.in is the live portal before citing it to end users.**

Documents required vary by applicant category but commonly include: water-requirement computation per the National Building Code 2016 (Annexure I of the 2020 guidelines), an affidavit (₹10 stamp paper) or certificate of non/inadequate availability of water from the local government supply agency, groundwater quality data from an NABL-accredited or government-approved lab, a rainwater-harvesting/recharge proposal per Model Building Bye-Laws, and — for industries/mining/infrastructure drawing >100 m³/day in Critical/Semi-Critical/Over-Exploited units — a formal hydrogeological/impact-assessment report by an accredited consultant.

Monthly groundwater-level monitoring. Confirmed against the primary Gazette text: Section 14.0 ("Ground Water Level Monitoring") requires all project proponents drawing more than 10 m³/day to mandatorily construct piezometers (observation wells) within their premises, with the number of piezometers and monitoring mechanism (manual / Digital Water Level Recorder (DWLR) / DWLR with telemetry) scaled by withdrawal volume per Table 14.1:

This is echoed in Section 4.1(iv) for industries specifically (construction mandatory for industries drawing >10 m³/day, piezometer sited ≥15 m from the pumping well) and Section 4.2(ii) for mining (piezometer along the periphery, for mines drawing >10 m³/day). Monthly water-level data must be submitted to CGWA through the web portal (Sections 4.1(iv), 9(v), and 14.0) — this is the "confirmed requirement" referenced in EarthReheal WasteLedger's earlier citation, and the primary source fully corroborates it.

Water quality monitoring: groundwater quality must be tested once a year (samples collected April/May, pre-monsoon) at an NABL-accredited lab, with results submitted to CGWA via the web portal (Section 9(vi)).

Water audit requirements: commercial entities extracting groundwater must submit an online annual water audit report (Section 4.0, general; Annexure X gives the CII-sourced audit methodology). Industries abstracting >100 m³/day specifically must have the audit performed by a CII/FICCI/National Productivity Council–certified auditor, submitted to CGWA within three months of completion, and must commit to a 20% reduction in groundwater use over the following three years.

Flow metering: a digital water flow meter conforming to BIS/IS standards, with telemetry, is mandatory for all NOC holders, to be installed and reported within 30 days of NOC grant, and calibrated annually by an authorised agency (Section 9(i)–(ii)).

Rainwater harvesting: mandatory rooftop rainwater harvesting/recharge is a general condition for all users (Section 9(iii)); polluting industries (chemical, pharma, dyes, tannery, pesticides, slaughterhouses, etc.) must store harvested rainwater in surface tanks rather than recharge it, to avoid contaminating groundwater. Sewage Treatment Plant (STP) installation becomes mandatory once groundwater requirement for residential apartments/group housing societies or new infrastructure projects exceeds 20 m³/day (Sections 2.0(i) and 4.3(ii)) — this is the STP trigger referenced above; confirm its interaction with the 2023 residential-exemption amendment against the official amendment notification.

NOC validity period and renewal (Section 11.0), confirmed from the primary text:

Renewal applications must be filed at least 90 days before expiry. If CGWA/the state authority cannot process a timely renewal application before expiry, the NOC is deemed extended until renewal is granted. If the holder fails to apply within 3 months of expiry, Environmental Compensation becomes payable for the gap period. Extensions (for holders unable to complete well construction within the validity window) are capped at a maximum of 2 years, with no further extension permitted after that — a fresh NOC application is required thereafter.

Penalties & Enforcement

Unauthorised (no-NOC) extraction — Environmental Compensation (Section 15.0): Groundwater extraction for commercial use without a valid NOC is deemed illegal and triggers Environmental Compensation calculated as:

EC = daily groundwater consumption (m³/day) × Environmental Compensation Rate (₹/m³) × number of days × deterrence factor

Rates scale by user category (packaged drinking water / mining & infrastructure dewatering / industrial) and by assessment-unit category, e.g. for industrial units: ₹20/m³ in Safe areas up to ₹200/m³ in Over-Exploited areas (5000+ m³/day tier); minimum EC in every case is ₹1,00,000. A deterrence multiplier further escalates the charge for extraction sustained beyond 2 years (up to 2.0× for >5000 KLD sustained beyond 5 years).

Non-compliance with NOC conditions — fixed penalty schedule (Section 16.0, Table 16.1), confirmed from the primary text — selected examples:

Enforcement mechanics: District Magistrates/District Collectors/Sub-Divisional Magistrates are designated CGWA "Authorised Officers" (Section 13.0) empowered to seal unauthorised abstraction structures, disconnect electricity to the energised well, launch prosecution, and impose Environmental Compensation. Violations may be prosecuted under Sections 15–21 of the Environment (Protection) Act, 1986 in the appropriate courts. Technical officers of CGWB/CGWA and state groundwater organisations conduct periodic compliance inspections. Persistent non-compliance is independently grounds for NOC cancellation or non-renewal (Section 17.0(iv)).

Frequently Asked Questions

Does a backup-only borewell (used only when municipal supply fails) need an NOC? Yes, if it draws groundwater above the exemption thresholds — CGWA's guidelines regulate the extraction structure and volume, not the frequency or "backup" purpose of use. A dormant/standby borewell that is registered but never energised still falls under the drilling-rig registration and "illegal abstraction structure" provisions if it is ever used to withdraw water without a valid NOC.

What if our facility draws less than 10 m³/day? If you are a Micro or Small Enterprise, you are exempt from NOC under Para 1.0(v) of the 2020 guidelines. If you're a larger entity (Medium enterprise or bigger) drawing under 10 m³/day but not purely for drinking/domestic use, you are not automatically exempt merely by volume — the MSE exemption is specifically tied to enterprise size (Micro/Small under the MSME Act classification), not to any organisation drawing a small quantity. The separate 5 m³/day exemption (2023 amendment) applies only to drinking/domestic-purpose extraction by industries/mining/infrastructure projects, in any assessment unit.

What's the difference between CGWA and my State Ground Water Authority? CGWA is the central regulator, but roughly a third of India's states/UTs (Karnataka, West Bengal, Kerala, Telangana, Andhra Pradesh, Himachal Pradesh, Goa, Jammu & Kashmir, Puducherry, plus several regulating via government order such as Tamil Nadu, Uttar Pradesh, Haryana, Punjab, and Delhi) have stood up their own groundwater regulator or bye-law regime. Where a state authority exists, it — not CGWA/Bhu-Neer — is your applicable NOC-issuing body, though CGWA's guidelines still act as a floor that state rules cannot fall below in substance.

How often do I need to report to CGWA once I have an NOC? Monthly for groundwater level (piezometer) data if you draw more than 10 m³/day; annually for groundwater quality testing (pre-monsoon window); annually for the water audit report if you're a commercial user (with the additional 100 m³/day trigger for a certified third-party audit); and within 30 days of NOC grant for flow-meter installation confirmation. All submissions route through the web portal (Bhu-Neer / relevant state portal).

Does agriculture need an NOC? No. The entire agriculture sector (irrigation use) is exempted from NOC under Para 3.0 of the guidelines, as a matter of stated policy — CGWA instead expects states to manage agricultural groundwater demand through electricity-pricing and water-pricing policy, not command-and-control permitting.

Can a defunct/dry borewell just be abandoned, or does it need to be sealed? It must be properly sealed per Annexure VII procedures (drawn from the Supreme Court's order in the "abandoned bore wells" child-safety case), and documentary proof of sealing submitted to CGWA. A replacement well can be drilled under intimation to CGWA if in the same premises; a fresh NOC is required if drilling at a different location.

What happens if we change ownership of a facility with an existing NOC? The new owner must apply to CGWA to incorporate the ownership change into the NOC, with documentary proof, within 60 days of taking possession (Section 9(ix)).

Are private water tanker operators covered by this rule? Yes — since the 2020 guidelines (formalised via the dedicated 2021 Bulk Water Supplier guidelines), all private tankers abstracting groundwater for bulk/tanker supply mandatorily need an NOC, issued by the relevant State/UT nodal authority (not directly by CGWA), with GPS tracking of tanker movement, tamper-proof telemetric flow meters, and daily withdrawal capped by assessment-unit category (50 m³/day in Over-Exploited, up to 150 m³/day in Safe areas).

Is saline groundwater treated the same way? No — abstraction of saline groundwater (in areas with saline water at all depths, or saline pockets) is exempted from abstraction charges to encourage its use over freshwater, though the same care regarding effluent disposal and aquifer protection applies, and a full NOC process is still followed. CGWA maintains a list of qualifying saline assessment units on its website.

Related Rules

• RULE_WATER_ACT_STP (Water (Prevention and Control of Pollution) Act, 1974 — Sewage Treatment Plant Consent, via SPCB) — a separate consent-to-establish/operate obligation that runs in parallel to CGWA's own STP-installation trigger (20 m³/day) for infrastructure/residential NOC holders. An organisation installing an STP to satisfy its CGWA NOC condition will typically also need the SPCB Water Act consent for that same STP — these are two distinct regulators/filings for what is functionally one piece of infrastructure.

If a dedicated RWH Rule Bible entry is created separately, it should cross-reference back to this document rather than duplicate the CGWA-mandated RWH condition.
