India draws more groundwater than any other country, and the 2026 monsoon has just ended 13% short. This research brief uses the 2025 national groundwater assessment, the latest national water quality data and IMD’s end-of-season figures to show where groundwater depletion in India is worst, what is polluting the water that remains, and which fixes are working on the ground, from village water budgets to building-level rainwater harvesting.

Scale

01

India pumps more groundwater than any other country, about 247 billion cubic metres a year

The Central Ground Water Board (CGWB) and the states assess India’s groundwater every year. The 2025 assessment puts total annual recharge at 448.52 billion cubic metres (bcm). After allowing for natural discharge, 407.75 bcm can be extracted, and the country actually extracted 247.22 bcm.[1] One bcm is a cubic kilometre, or a lakh crore litres.

The UN’s World Water Development Report 2022 names India as the largest groundwater user in the world, at about 251 cubic kilometres a year in its dataset, with 89% going to irrigation.[4] Groundwater now meets about 64% of India’s irrigation needs, about 85% of rural water supply and about 50% of urban water use.[1]

Nearly all of it goes to farms. Of the water extracted in 2025, 87% went to irrigation, 11% to domestic use and 2% to industry.[1] Worldwide the split is 69% for agriculture, 22% for domestic use and 9% for industry,[4] so India’s groundwater is far more concentrated on fields than the global average.

What it means

Any serious plan on groundwater depletion in India is first a farm plan. Industry’s 2% share is small nationally, but one factory can be a large share of one block, which is why the local category of a site matters more than the national average.

Hotspots

02

730 of India’s 6,762 assessment units draw more groundwater than they recharge

CGWB grades each assessment unit, which is a block, mandal, taluk or firka depending on the state, by its stage of extraction. That is the share of the extractable groundwater that is actually being used. A unit at 70% or less is safe. Above 70% and up to 90% is semi-critical, above 90% and up to 100% is critical, and above 100% is over-exploited.[1]

In 2025, 730 units (10.80%) were over-exploited, 201 (2.97%) critical and 758 (11.21%) semi-critical. 4,946 units (73.14%) were safe, and 127 (1.88%) were classed as saline.[1] The over-exploited units cover about 4.16 lakh square kilometres, 16.85% of the area assessed, and hold 44.66 bcm, or 10.95%, of the country’s extractable groundwater.[1]

The report finds three clusters. In the north-west, in parts of Punjab, Haryana, Delhi and western Uttar Pradesh, recharge is abundant but “indiscriminate withdrawals” have caused over-exploitation. In the west, in Rajasthan and Gujarat, the arid climate limits recharge itself. In the southern peninsula, in parts of Karnataka, Tamil Nadu, Telangana and Andhra Pradesh, hard-rock crystalline aquifers simply hold less water.[1]

What it means

A national stage of extraction of about 60% hides blocks running well past 100%. CSR water projects and corporate water risk screens should start from the published CGWB category of the specific block, not the state or national figure.

Farms

03

Punjab, Rajasthan and Haryana pump 1.4 to 1.6 times what their aquifers can give

Only three states have a stage of extraction above 100%. Punjab extracted 26.27 bcm in 2025 against 16.80 bcm that can be extracted sustainably, a stage of 156.36%, and 24.89 bcm of that went to irrigation. Rajasthan stands at 147.11% and Haryana at 136.75%.[1] In Haryana, 91 of 143 units are over-exploited.[5]

Punjab’s gap between what it pumps and what it can sustainably draw is about 9.5 bcm a year, more than twice what all of Indian industry extracts (4.23 bcm).[1] The cause is not a lack of rain. CGWB describes the north-western cluster as one where recharge is abundant and withdrawal is the problem.[1]

Depletion in the north-west also shows up in water quality. In CGWB’s 2024 uranium survey of 3,754 samples, 6.71% of pre-monsoon and 7.91% of post-monsoon samples nationally were above 30 parts per billion. In Punjab the shares were 53.04% and 62.50%, with Haryana at 15% to 23.75% and Delhi at 13% to 15.66%. CGWB says the north-western hotspot is “likely due to geogenic factors, groundwater depletion, and aquifer characteristics”.[2]

24.89 bcmGroundwater Punjab draws for irrigation in a year [1]
53.04%Pre-monsoon samples in Punjab above the uranium limit, 2024 [2]
What it means

In the north-west, groundwater depletion is a question of what is grown and how it is watered. Recharge alone cannot close a 9.5 bcm gap. Crop choice, irrigation scheduling and drip systems that farmers can maintain are where the water is.

Trend

04

The national numbers have improved since 2017, but half of monitored wells were below their ten-year average

On paper, India’s groundwater has been recovering. Between the 2017 and 2025 assessments, annual recharge rose from 431.86 bcm to 448.52 bcm and the stage of extraction fell from 63.33% to 60.63%. Safe units rose from about 63% to 73.14% of the total, and over-exploited units fell from about 17% to 10.80%.[5][6] The CGWB report credits “good continuous rainfall” in some areas, along with recharge and conservation work under central and state programmes.[1]

Extraction has not fallen, though. It rose from 245.64 bcm in 2024 to 247.22 bcm in 2025. Recharge rose a little faster, from 446.9 bcm to 448.52 bcm.[1] The water levels in wells give a more mixed picture. When pre-monsoon 2024 levels were compared with the 2014 to 2023 average, 50.3% of the monitored wells (6,811 of them) showed a decline and 49.6% a rise.[1]

What it means

The direction of the national numbers is good news. But a falling well is a local fact for the family or farm that depends on it. Progress should be judged block by block and well by well, and any recharge programme should report the wells it watches.

Monsoon 2026

05

The 2026 monsoon ended 13% short, and the east and south took the biggest hit

Rain is the aquifer’s main income. Rainfall provides about 60% of India’s annual groundwater recharge, 269.17 bcm in 2025, and more than 75% of the year’s rain falls between June and September.[1] So the monsoon that ended on 30 September matters for next year’s wells.

The India Meteorological Department reports that India received 759.4 mm of rain from June to September 2026, 87% of the long period average of 868.6 mm. That makes it the fourth lowest since 2001 and the 13th lowest since 1901. The South Peninsula got 76% of normal, its fourth lowest since 1901, and East and North East India got 74%, the lowest since 1901. North-west India received 94% and central India 97%. In all, 17 of 36 meteorological sub-divisions, covering 42% of the country’s area, were deficient.[3] The season also started badly, with June at 65% of normal, July at 101%, August at 84% and September at 92%.[3]

The south is where a weak monsoon bites fastest. Its crystalline hard-rock aquifers hold little water to begin with.[1] Heat adds to the pressure. A 2023 study in Science Advances found that Indian farmers pump more groundwater as temperatures rise, and projected that, with continued warming, depletion rates in 2041 to 2080 could be about three times today’s (3.26 times, with a range of 1.62 to 4.45 across scenarios).[7]

Rain is the aquifer’s main income, and most of it falls in four months. An Earth5R volunteer briefs young volunteers before a monsoon lake cleanup, July 2018.
What it means

Expect the 2027 pre-monsoon well readings in the south and east to show this year’s shortfall. Recharge pits cleaned, tanks desilted and rooftops connected before June 2027 will be worth more than usual, because the aquifers they feed start the season lower.

Water quality

06

One in five groundwater samples breaks the drinking water limit for nitrate

Less water is one problem. Dirtier water is the other. CGWB’s Annual Ground Water Quality Report 2025 tested 14,978 samples taken before the 2024 monsoon. 71.7% met the Bureau of Indian Standards limits on every parameter tested, and 28.3% exceeded at least one.[2] The government’s summary is that groundwater is “largely potable with localized occurrences” of contamination.[8]

Nitrate is the most widespread problem. 20.71% of samples were above 45 mg/L, a share that has stayed between 19.5% and 21.3% every year since 2017. The report links high nitrate to intensive farming, excessive fertiliser use and the poor disposal of domestic and animal waste. In the Indo-Gangetic plains it points to “unlined sanitation systems” and leaching from fields.[2] In some states the share is far higher. Of the samples tested, 325 of 643 in Rajasthan, 181 of 398 in Karnataka, 337 of 929 in Tamil Nadu and 531 of 1,565 in Maharashtra were above the nitrate limit.[2]

Source: CGWB, Annual Ground Water Quality Report 2025.[2] The uranium figure is from the trace metal set. The separate uranium survey of 3,754 samples found 6.71% above 30 ppb before the monsoon.

Salinity is creeping up too. The share of samples with high electrical conductivity rose from 5.54% in 2017 to 7.23% in 2024, and fluoride was above the limit in 8.05%.[2]

What it means

Depletion and pollution are one problem seen from two sides. Overused fertiliser, open drains and leaking septic systems feed the nitrate in wells, so cutting fertiliser, segregating waste and treating sewage are groundwater work as much as pumping less is.

Cities

07

Cities rely on groundwater for about half their water, and Delhi already uses 92% of its share

Groundwater meets about half of urban water use in India.[1] Delhi’s stage of extraction is 92.10%, in the critical band.[1] Of its 34 assessment units, 10 are over-exploited and 11 more are critical.[5] Puducherry is at 75.98% and Chandigarh at 67%.[1]

Demand from homes will keep rising. The 2025 assessment sets aside 36.42 bcm for domestic use in 2035, against the 27.89 bcm drawn for domestic use today.[1] City sinking is often linked to over-pumping in news reports, but in July 2026 the Ministry of Jal Shakti told Parliament that land subsidence is localised and that it has no state-wise attribution of subsidence to groundwater extraction.[5] The firmer evidence for cities is in the extraction numbers.

Every doorway in this lane stores water. Where supply is uncertain, households fill drums, and the city draws more from the ground. An Earth5R session with residents, 2017.

Buildings can do a lot within their own walls. In Earth5R’s urban water conservation programme, buildings that adopted conservation measures cut their water use by an average of 5,800 litres a month, a 24% to 28% reduction, through rainwater harvesting, wastewater recycling and fixture upgrades.[9] The full case study and the field evidence section below give the details.

What it means

City water plans should count borewells and recharge pits the way they count pipes. Rooftop rainwater harvesting and the reuse of treated wastewater in large buildings are levers that a housing society, a campus or a company controls directly.

What works

08

Where villages measured their own water, 180 of 229 blocks improved

India has built recharge structures at a scale few countries match. More than 2 crore water conservation and artificial recharge works have been carried out through the Jal Shakti Abhiyan since 2019. The Jal Sanchay Jan Bhagidari initiative, launched in 2024, has added more than 1.55 crore recharge and storage works, and nearly 69,000 Amrit Sarovars have been built or revived.[5] About ₹1.5 lakh crore has been spent on this since 2021 through convergence with MGNREGS alone, and the Master Plan for Artificial Recharge of Groundwater, 2020 envisages about 1.42 crore structures to harness 185 bcm of monsoon rainfall.[8] Since September 2025, at least 65% of MGNREGS funds in over-exploited and critical blocks, and 40% in semi-critical blocks, must go to water works.[6]

The Atal Bhujal Yojana tried something different. From April 2020 to October 2025 it worked on the demand side in 8,203 gram panchayats across 229 blocks, 80 districts and seven states. Every gram panchayat prepared a water budget and a water security plan, updated each year. There were more than 1.28 lakh gram panchayat level trainings, NGOs served as district implementation partners, and at least 33% participation by women in decision-making was mandatory. Communities monitored around 70,000 wells and shared the data publicly, mapped more than 99,000 existing structures, and brought around 9.7 lakh hectares under drip, sprinkler, mulching or crop diversification.[10] In the 2023 to 2025 assessment, 180 of the 229 blocks showed improved groundwater levels, including 39 of 43 in Maharashtra.[10]

Earth5R has written about how small structures add up in micro-watershed water harvesting and in community-driven rainwater harvesting.

What it means

Structures add storage. Budgets change behaviour. The Atal Bhujal results suggest the two work best together, with the community holding the measuring tape. A CSR recharge project should fund the monitoring and the maintenance, not only the concrete.

Farms

09

Only about 8% of India’s farmland is under drip or sprinkler irrigation

With 87% of extraction going to irrigation, the biggest saving sits on farms. Per Drop More Crop, the national micro-irrigation scheme, had brought more than 115 lakh hectares under drip and sprinkler irrigation by July 2026. That is about 8.11% of India’s net sown area. Around half of the net sown area is irrigated at all. The scheme pays 55% of the cost for small and marginal farmers and 45% for others.[11]

Earth5R’s agriculture programme shows why the hardware alone is not enough. Between 2018 and 2025, Earth5R volunteers and community leaders trained 12 lakh farmers across 14 states and 2 union territories in five practices together: organic practice, drip irrigation, residue management, solar pumping and financial literacy.[13] The case study is blunt about the problem. “Groundwater is pumped beyond replacement because flood irrigation is what the equipment allows,” it says, and “a farmer who installs drip irrigation but has no savings cannot replace an emitter when it fails.”[13]

So the training was held on the plot, in the season the practice applies to, with the trainer travelling and the farmer staying on the land. Farmer cooperatives, not individuals, were the unit of adoption, so that equipment and confidence could be shared. Trained farmers reported using 40% less synthetic fertiliser. Earth5R states that this figure is self-reported and was not soil tested.[13] If it holds, it also matters for the nitrate in section 06.

What it means

Drip systems save water only while they keep working. Programmes that pair subsidy with repair skills, group finance and in-season training at the plot turn a one-time installation into a lasting change. Read the full Earth5R agriculture case study.

Business

10

Listed companies must disclose how much groundwater they draw, and new large industry is barred in over-exploited blocks

Industry draws only 2% of India’s groundwater,[1] but it faces the sharpest rules. SEBI’s Business Responsibility and Sustainability Report (BRSR) asks listed companies to report water withdrawal by source, with groundwater as its own line, along with total consumption and water intensity. A leadership indicator asks for the same figures for sites in areas of water stress.[12]

The Central Ground Water Authority’s guidelines of 24 September 2020 brought in higher extraction charges and heavier environmental compensation for illegal use, and they prohibit new large-scale industries in over-exploited blocks.[6] CGWA regulates extraction by industry and infrastructure projects in 19 states and union territories. The other 17 have their own regulatory frameworks.[5] For CSR, Schedule VII of the Companies Act lists conservation of natural resources and maintaining the quality of soil, air and water as eligible activities.[14]

Earth5R’s ESG and BRSR reporting services cover the BRSR water lines, and our analysis of data centres and water in India shows how a new industry adds to local demand.

What it means

For a company, groundwater depletion in India is now a disclosure, a licence and a local reputation issue at once. A site in an over-exploited block that cannot show its withdrawal and its community water work will find all three harder to hold.

Earth5R method

Earth5R’s five R’s, applied to groundwater

Earth5R’s name comes from a sequence it has taught since 2014: Respect, Reduce, Reuse, Recycle, Restore. “The order matters,” Earth5R founder Saurabh Gupta writes. “Respect comes first, respect for nature, for communities and for the limits of growth.”[15] For groundwater, each R points to a concrete task.

The five R’s applied to groundwater

RespectStart from the limit. A block’s CGWB category and its water budget tell you what the aquifer can give before anyone plans to draw more.Door-to-door volunteers explaining scarcity to residents, building by building[9]
ReducePump less: drip and scheduled irrigation on farms, low-flow fixtures and leak fixes in buildings.Drip irrigation training for 12 lakh farmers[13], an average 5,800 litres a month saved per adopting building[9]

RecycleClose the loop on waste and nutrients so they do not leach into aquifers as nitrate and other pollutants.Paid collection of segregated plastic in the Mithi catchment, fertiliser cuts reported by trained farmers[16][13]

The five R’s, printed on the backs of Earth5R volunteers during a 2018 session in a residential lane. For groundwater, Respect means knowing what the aquifer can give before deciding how to use it.

The order is the point. A programme that starts at Recycle has skipped the three most important steps.[15] A recharge pit built in a block that keeps pumping at 150% of its limit is Restore without Respect or Reduce.

Field evidence

What Earth5R’s field programmes show about groundwater work that lasts

Case study 1: door-to-door water conservation in urban buildings, 2015 to 2025

Earth5R’s urban water conservation programme ran across 28 states and 8 union territories from January 2015 to December 2025. It grew from 1,800 volunteers reaching 7,200 buildings in 2015 to 4,800 trained volunteers and more than 4,90,000 buildings reached by 2025. More than 34,300 buildings adopted conservation measures, an average adoption rate of 7%. Programme records count more than 3,840 rainwater harvesting systems and more than 2,610 buildings that adopted wastewater recycling, with 16.9 billion litres of water saved in total.[9]

Three findings are useful for anyone designing a groundwater programme. First, awareness is not action. By 2023, 82% of urban residents surveyed saw water scarcity as a serious local problem, yet only 6.8% had adopted any conservation technology in their building. Second, the door-to-door volunteer model produced adoption rates three to four times higher than mass media campaigns alone. Third, buildings that combined rainwater harvesting, wastewater recycling and fixture upgrades saved 2.3 times as much water as those that adopted one method. The programme names its main constraint as keeping volunteers.[9]

Case study 2: Powai Lake and the Mithi River, Mumbai

Lakes and rivers are part of the recharge system, and keeping waste and sewage out of them protects the water below. At Powai Lake, Earth5R ran a cleanup every Sunday for 208 consecutive weeks, with an average of 70 volunteers, held 208 educational events reaching more than 50,000 residents, and brought more than 50 local waste collectors into the work. Dumping at the lake fell by 35%.[17] On the Mithi River, from October 2020 to November 2024, the programme removed 11,100 tonnes of waste, including 4,440 tonnes of plastic, trained 10,000 families and 500 businesses in the catchment, and worked with 15,000 volunteers. Residents were paid for segregated plastic, which turned collection into income.[16] Earth5R’s ecosystem approach to urban lakes and the river cleanup CSR project describe the model in full.

Case study 3: farmers trained at the plot

The agriculture programme in section 09 reached its 12 lakh farmers through community leaders who live where they train, part of an Earth5R network of 98,073 community leaders in 5,526 locations.[13]

About these figures. All Earth5R figures in this article are programme-reported by Earth5R and have not been independently audited. For the urban water programme, Earth5R reports that savings were checked against utility consumption records for a 35% sample of adopting buildings each year, and estimated for the rest using technology-specific savings factors.[9] The fertiliser figure in the agriculture programme is self-reported by farmers.[13] None of these figures is a measured change in groundwater levels. They show what building-level and farm-level action looks like at scale.

For companies, CSR teams and city agencies, Earth5R offers measured water programmes in the buildings, farms and catchments where their people and suppliers are, with reporting that fits BRSR. See Earth5R’s CSR and ESG projects.

Action

What to do about groundwater depletion before the 2027 monsoon

Companies and CSR teams

Look up the CGWB category of every block where you have a site or a key supplier. Meter groundwater withdrawal and report it in BRSR as its own line.[12] Fund demand-side work, such as water budgets and farmer training, alongside recharge, and pay for the monitoring and maintenance that show whether it worked. Employees can take part through corporate volunteering.

Housing societies, campuses and city agencies

Audit rooftop rainwater harvesting and recharge pits before the rains, since many stop working when they silt up. Reuse treated wastewater for flushing and gardens. Earth5R’s evidence suggests combining methods saves 2.3 times as much as using one.[9]

Students and young people

Groundwater needs people who can read a well, a water bill and a policy. Earth5R’s water resources internship and sustainability courses are a way in, and volunteers can join field programmes through the Earth5R team.

Researchers and policymakers

The national assessment shows categories improving while half of monitored wells fell against their ten-year average.[1] Linking structure data, well data and water budgets at block level, as Atal Bhujal began to do with public well data,[10] would show which recharge works actually recharge.

Questions

Frequently asked questions about groundwater depletion in India

How serious is groundwater depletion in India?
India extracted 247.22 bcm of groundwater in 2025, 60.63% of what can be extracted sustainably. Nationally that is moderate, but 730 of 6,762 assessment units draw more than they recharge, and half of monitored wells were below their 2014 to 2023 average in 2024.[1]
Which states have the worst groundwater depletion?
Punjab (156.36%), Rajasthan (147.11%) and Haryana (136.75%) are the only states drawing more than 100% of their extractable groundwater. Delhi is at 92.10%, in the critical band.[1]
What causes groundwater depletion in India?
Mainly irrigation, which takes 87% of extraction. Withdrawal beyond recharge in the north-west, low recharge in the arid west and low-storage hard-rock aquifers in the south are the three main patterns.[1] Warming is expected to increase pumping.[7]
Is groundwater in India safe to drink?
Mostly, but not everywhere. In 2024, 71.7% of CGWB samples met BIS limits on every parameter tested. Nitrate was above the limit in 20.71% of samples, fluoride in 8.05% and arsenic in 3.45%.[2] Test a well before relying on it.
How will the weak 2026 monsoon affect groundwater?
Rainfall provides about 60% of recharge.[1] The 2026 monsoon brought 87% of normal rain, with the South Peninsula at 76% and East and North East India at 74%,[3] so lower recharge is likely in those regions before the 2027 monsoon.
What should companies do about groundwater?
Know the CGWB category of each site’s block, report groundwater withdrawal in BRSR, follow CGWA rules, which bar new large industry in over-exploited blocks, and fund measured recharge and demand-side work in the same catchment.[12][6]
How can citizens help save groundwater?
Fix leaks, install low-flow fixtures, harvest rooftop rain into recharge pits, reuse treated wastewater and keep waste out of lakes and drains. In Earth5R’s urban programme, adopting buildings saved an average of 5,800 litres a month.[9]
