Switch thirsty crops, water by drip
Where most water goes to fields, moving from paddy and sugarcane to millets, pulses or maize, and from flood to drip or sprinkler irrigation, saves more than any recharge can add.
This area pumps out 1.6 times the water that rain puts back. That is the 2025 stage of groundwater extraction: water pumped out in a year as a share of what rain and other sources safely put back. Up 17 points since 2017.
Each point is one CGWB assessment. Over-exploited means more water leaves the ground than comes back, so the water table keeps falling. Hover over or tap a point to see why it moved.
| Year | Stage | Pumped out | Safe limit | Category | What changed |
|---|---|---|---|---|---|
| 2009 | 136.0% | 524 million m³ | 387 million m³ | Over-exploited | First assessment in this series. |
| 2013 | 140.0% | 603 million m³ | 430 million m³ | Over-exploited | Pumping up 15% (524 → 603 million m³). Safe limit up 11% (387 → 430 million m³). Main reason: more water was pumped out, mostly for irrigation (496 → 561 million m³). |
| 2017 | 138.7% | 754 million m³ | 544 million m³ | Over-exploited | Pumping up 25% (603 → 754 million m³). Safe limit up 26% (430 → 544 million m³). CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 148.9% | 579 million m³ | 389 million m³ | Over-exploited | Pumping down 23% (754 → 579 million m³). Safe limit down 28% (544 → 389 million m³). Main reason: less water soaked back in, from weaker rain, less canal seepage or more paved ground. |
| 2022 | 152.2% | 664 million m³ | 436 million m³ | Over-exploited | Pumping up 15% (579 → 664 million m³). Safe limit up 12% (389 → 436 million m³). Main reason: more water was pumped out, mostly for irrigation (531 → 602 million m³). |
| 2023 | 163.3% | 663 million m³ | 406 million m³ | Over-exploited | Pumping down 0% (664 → 663 million m³). Safe limit down 7% (436 → 406 million m³). Main reason: less water soaked back in, from weaker rain, less canal seepage or more paved ground. |
| 2024 | 156.7% | 641 million m³ | 409 million m³ | Over-exploited | Pumping down 3% (663 → 641 million m³). Safe limit up 1% (406 → 409 million m³). Main reason: less water was pumped out, mostly for irrigation (602 → 586 million m³). |
| 2025 | 155.8% | 635 million m³ | 408 million m³ | Over-exploited | Pumping down 1% (641 → 635 million m³). Safe limit down 0% (409 → 408 million m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

385 of 1,877 water bodies (21%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

Most of the water here goes to farming, so using less on fields matters as much as recharge.
Where most water goes to fields, moving from paddy and sugarcane to millets, pulses or maize, and from flood to drip or sprinkler irrigation, saves more than any recharge can add.
Parks, campuses, warehouse yards and road sides can take recharge shafts that reach past the clay layer, so runoff that floods streets goes down to the aquifer instead.
Desilting old ponds and opening their feeder channels restores natural recharge. A one-hectare pond that soaks in a metre of water over the monsoon puts back about a crore litres.
Pipe roof water through a silt trap and filter into a recharge pit or an old borewell. Every 100 m² of roof puts back tens of thousands of litres a year, right where the pumping happens.
On sloping or rocky land, small dams on seasonal streams and trenches along contours slow water down long enough for it to sink in.
Treated water from a sewage treatment plant can run flushing, gardens, cooling towers and construction, which today often draw on borewells.
In the 2025 Central Ground Water Board assessment, Bhilwara (Rajasthan) pumped out 156% of the groundwater that can be safely taken out each year, which puts it in the "over-exploited" category. That is 17 points higher than in 2017.
Yes. Bhilwara takes out more groundwater than rain and other sources put back, so the water table keeps falling.
Rooftop rainwater harvesting into recharge pits or old borewells, recharge shafts in open land, reviving ponds, check dams, treating and reusing wastewater, and moving farms to drip irrigation and less thirsty crops.
The first Census of Water Bodies counted 1,877 water bodies in Bhilwara, including 309 ponds. 385 of them were not in use.
Yearly rain at Bhilwara, 2006–2025, from NASA satellite data. Lighter bars are dry years (20% or more below average), when wells are drawn hardest.
To stop the water table falling, Bhilwara has to put back or save 228 million m³ a year. At 753 mm of rain, here is what that looks like:
In practice it is a mix: recharge in towns, ponds and check dams in villages, and saving water on farms and in factories.
1 mm of rain on 1 m² is 1 litre. The surface factor allows for water lost to splash, evaporation and first-flush.
