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 use is within safe limits 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. Down 31 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 | 36.0% | 494 million m³ | 1.4 billion m³ | Safe | First assessment in this series. |
| 2013 | 39.0% | 608 million m³ | 1.5 billion m³ | Safe | Pumping up 23% (494 → 608 million m³). Safe limit up 11% (1.4 → 1.5 billion m³). Main reason: more water was pumped out, mostly for irrigation (471 → 598 million m³). |
| 2017 | 41.4% | 756 million m³ | 1.8 billion m³ | Safe | Pumping up 24% (608 → 756 million m³). Safe limit up 18% (1.5 → 1.8 billion m³). CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 28.5% | 488 million m³ | 1.7 billion m³ | Safe | Pumping down 35% (756 → 488 million m³). Safe limit down 6% (1.8 → 1.7 billion m³). Main reason: less water was pumped out, mostly for irrigation (719 → 439 million m³). A swing this large usually comes partly from revised estimates (a new well count or changed district boundaries), not only from changes on the ground. |
| 2022 | 10.8% | 62.1 million m³ | 573 million m³ | Safe | Pumping down 87% (488 → 62 million m³). Safe limit down 67% (1.7 → 0.6 billion m³). Main reason: less water was pumped out, mostly for irrigation (439 → 57 million m³). A swing this large usually comes partly from revised estimates (a new well count or changed district boundaries), not only from changes on the ground. |
| 2023 | 11.0% | 62.8 million m³ | 572 million m³ | Safe | Pumping up 1% (62 → 63 million m³). Safe limit down 0% (573 → 572 million m³). |
| 2024 | 8.3% | 44.4 million m³ | 531 million m³ | Safe | Pumping down 29% (63 → 44 million m³). Safe limit down 7% (572 → 531 million m³). |
| 2025 | 9.9% | 48.8 million m³ | 492 million m³ | Safe | Pumping up 10% (44 → 49 million m³). Safe limit down 7% (531 → 492 million m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.
Loading 20 years of rainfall…
Groundwater here is in balance. Keeping it that way means recharging as the area builds up and paves over.
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, West Godavari (Andhra Pradesh) pumped out 10% of the groundwater that can be safely taken out each year, which puts it in the "safe" category. That is 31 points lower than in 2017.
No. At 10% of the safe yield, West Godavari is safe, 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.
