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 8 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 |
|---|---|---|---|---|---|
| 2013 | 51.0% | 864 million m³ | 1.7 billion m³ | Safe | First assessment in this series. |
| 2017 | 68.3% | – | – | Safe | CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 80.2% | 186 million m³ | 232 million m³ | Semi-critical | Up 12 points since 2017. |
| 2022 | 67.0% | 190 million m³ | 285 million m³ | Safe | Pumping up 2% (186 → 190 million m³). Safe limit up 22% (232 → 285 million m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
| 2023 | 58.8% | 198 million m³ | 336 million m³ | Safe | Pumping up 4% (190 → 198 million m³). Safe limit up 18% (285 → 336 million m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
| 2024 | 70.6% | 223 million m³ | 315 million m³ | Semi-critical | Pumping up 12% (198 → 223 million m³). Safe limit down 6% (336 → 315 million m³). Main reason: more water was pumped out, mostly for irrigation (190 → 214 million m³). |
| 2025 | 76.2% | 252 million m³ | 331 million m³ | Semi-critical | Pumping up 13% (223 → 252 million m³). Safe limit up 5% (315 → 331 million m³). Main reason: more water was pumped out, mostly for irrigation (214 → 238 million m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.
Loading 20 years of rainfall…
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, Mahabubnagar (Telangana) pumped out 76% of the groundwater that can be safely taken out each year, which puts it in the "semi-critical" category. That is 8 points higher than in 2017.
No. At 76% of the safe yield, Mahabubnagar 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.
