Policy reference
India's water problem is not primarily one of total volume. It is one of timing, distribution, storage and the rate at which groundwater is drawn down — and it is measured, block by block, every year.
India receives a large volume of rainfall, but it receives most of it in a few months and it does not fall where demand is highest. The monsoon delivers the bulk of annual precipitation in roughly a hundred days; the country then has to live off storage — in reservoirs, in soil moisture, and above all in aquifers — for the rest of the year.
That dependence on aquifers is the central fact of Indian water management. It is what makes groundwater assessment a policy instrument rather than a scientific exercise, and it is why a great deal of the government's conservation effort is directed at recharge rather than at extraction alone.
A second structural fact follows from the first: the great majority of extracted water is used for irrigation, not for drinking. Domestic supply is a small share of total demand but the least substitutable share of it. Policy on water security is therefore largely policy about agriculture, with drinking water protected as a first charge on the resource.
The Central Ground Water Board, working with State governments, assesses the country's dynamic groundwater resources each year. The 2025 assessment was placed before the Lok Sabha on 29 January 2026 in a reply by the Union Minister of Jal Shakti.
Total annual groundwater recharge
Annual extractable groundwater resources
Total annual groundwater extraction, all uses
Stage of groundwater extraction, nationally
Assessment units — generally blocks, tehsils, talukas or mandals — are classified by their stage of extraction: annual extraction as a proportion of the annual extractable resource.
| Category | Stage of extraction | Share of units |
|---|---|---|
| Safe | Below 70 per cent | 73.14% |
| Semi-critical | 70 to 90 per cent | 11.21% |
| Critical | 90 to 100 per cent | 2.97% |
| Over-exploited | Above 100 per cent | 10.80% |
| Saline | Classified separately | 1.88% |
Over-exploited units are concentrated in north-western, western and southern India.
The same assessment, compared across editions, is the clearest published indicator of whether the national groundwater position is improving or deteriorating.
Over the same period, total annual recharge is assessed to have risen from 432 BCM to 448.52 BCM. The government attributes the improvement to sustained recharge and conservation effort; this page reports the figures and that attribution without independently verifying the causal claim.
Six distinct pressures, which require different instruments and are frequently confused with one another in public debate.
Irrigation accounts for by far the largest share of water use. Cropping choices, the economics of power supply to agricultural pumps, and procurement policy all shape groundwater draw more directly than any water regulation does.
The volume is not the difficulty; the distribution is. Rain concentrated in a short season, and varying sharply between years and districts, makes storage and recharge the binding constraints.
The same country, and sometimes the same state within the same year, experiences both. Flood management and drought mitigation are not opposites but two expressions of a single failure to hold water in the right place at the right time.
Urban systems draw on distant sources, lose a substantial share in transmission, and return waste water that has to be treated before it re-enters a river or aquifer. Urban water and urban sanitation are one system, not two.
Fluoride, arsenic, iron, nitrate and salinity render water unusable without treatment even where it is physically available. Quality failure reduces the effective resource just as surely as extraction does.
Shifts in the intensity and timing of precipitation alter the assumptions on which existing storage and recharge infrastructure was designed. Resilience means designing for a distribution that is itself changing.
Because water is a State subject, the Union's instruments are largely scientific, financial and regulatory rather than executive. Understanding which lever belongs to whom is the difference between informed criticism and misdirected criticism.
Science
The annual Dynamic Ground Water Resource Assessment classifies every assessment unit and so determines where effort is concentrated. Under the National Aquifer Mapping programme, about 25 lakh square kilometres — the entire mappable area of the country — was covered in its first phase, with district-wise aquifer maps and management plans shared with local administrations. NAQUIM 2.0 is now under way in priority areas.
Regulation
Guidelines dated 24 September 2020 apply more stringent conditions in over-exploited, critical and semi-critical blocks: higher extraction charges, heavier environmental compensation and penalties, and a prohibition on new large-scale industry in over-exploited blocks.
Community
A participatory groundwater management scheme implemented in 80 water-stressed districts across seven States, designed to establish a decentralised governance model by training communities to manage their own groundwater. More than 83,000 rainwater harvesting and recharge structures were completed or rejuvenated under it, and more than 9 lakh hectares were brought under efficient irrigation practices.
Convergence
Launched jointly by the Ministry of Rural Development and the Ministry of Jal Shakti in September 2025. Under it, at least 65 per cent of MGNREGS funds are to be spent on water conservation works in over-exploited and critical blocks, and 40 per cent in semi-critical blocks — directing the country's largest rural employment programme at the blocks the groundwater assessment identifies.
Campaign
Annual recharge and rainwater harvesting campaigns run across all districts, with priority areas selected from the groundwater assessment. Set out in full on the conservation page.
Water policy is an area in which four quite different kinds of statement are routinely presented as though they were the same thing. This page tries to keep them apart, and it is worth being explicit about the distinction.
