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.
Groundwater is under pressure here. 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 1 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 | 102.0% | 561 million m³ | 552 million m³ | Over-exploited | First assessment in this series. |
| 2013 | 77.0% | 425 million m³ | 553 million m³ | Semi-critical | Pumping down 24% (561 → 425 million m³). Safe limit up 0% (552 → 553 million m³). Main reason: less water was pumped out, mostly for irrigation (492 → 351 million m³). |
| 2017 | 72.0% | 396 million m³ | 550 million m³ | Semi-critical | Pumping down 7% (425 → 396 million m³). Safe limit down 1% (553 → 550 million m³). Main reason: less water was pumped out, mostly for homes and industry (74 → 37 million m³). CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 64.6% | 392 million m³ | 606 million m³ | Safe | Pumping down 1% (396 → 392 million m³). Safe limit up 10% (550 → 606 million m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
| 2022 | 85.5% | 370 million m³ | 433 million m³ | Semi-critical | Pumping down 5% (392 → 370 million m³). Safe limit down 29% (606 → 433 million m³). Main reason: less water soaked back in, from weaker rain, less canal seepage or more paved ground. |
| 2023 | 87.3% | 371 million m³ | 424 million m³ | Semi-critical | Pumping up 0% (370 → 371 million m³). Safe limit down 2% (433 → 424 million m³). |
| 2024 | 73.6% | 311 million m³ | 423 million m³ | Semi-critical | Pumping down 16% (371 → 311 million m³). Safe limit down 0% (424 → 423 million m³). Main reason: less water was pumped out, mostly for irrigation (327 → 252 million m³). |
| 2025 | 72.7% | 307 million m³ | 423 million m³ | Semi-critical | Pumping down 1% (311 → 307 million m³). Safe limit up 0% (423 → 423 million m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

63 of 1,964 water bodies (3%) 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.
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.
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.
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, Ahmedabad (Gujarat) pumped out 73% of the groundwater that can be safely taken out each year, which puts it in the "semi-critical" category. That is 1 points higher than in 2017.
No. At 73% of the safe yield, Ahmedabad is semi-critical, though recharge is still needed as demand grows.
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 1,964 water bodies in Ahmedabad, including 417 ponds. 63 of them were not in use.
