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 4 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 | 59.0% | 131 million m³ | 222 million m³ | Safe | First assessment in this series. |
| 2013 | 62.0% | 148 million m³ | 238 million m³ | Safe | Pumping up 13% (131 → 148 million m³). Safe limit up 7% (222 → 238 million m³). Main reason: more water was pumped out, mostly for irrigation (110 → 121 million m³). |
| 2017 | 61.3% | 127 million m³ | 207 million m³ | Safe | Pumping down 14% (148 → 127 million m³). Safe limit down 13% (238 → 207 million m³). CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 54.4% | 142 million m³ | 261 million m³ | Safe | Pumping up 12% (127 → 142 million m³). Safe limit up 26% (207 → 261 million m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
| 2022 | 60.3% | 176 million m³ | 292 million m³ | Safe | Pumping up 24% (142 → 176 million m³). Safe limit up 12% (261 → 292 million m³). Main reason: more water was pumped out, mostly for irrigation (127 → 146 million m³). |
| 2023 | 56.2% | 164 million m³ | 291 million m³ | Safe | Pumping down 7% (176 → 164 million m³). Safe limit down 0% (292 → 291 million m³). Main reason: less water was pumped out, mostly for homes and industry (30 → 18 million m³). |
| 2024 | 55.3% | 161 million m³ | 292 million m³ | Safe | Pumping down 1% (164 → 161 million m³). Safe limit up 0% (291 → 292 million m³). |
| 2025 | 56.9% | 169 million m³ | 298 million m³ | Safe | Pumping up 5% (161 → 169 million m³). Safe limit up 2% (292 → 298 million m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

41 of 87 water bodies (47%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

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, Dharwad (Karnataka) pumped out 57% of the groundwater that can be safely taken out each year, which puts it in the "safe" category. That is 4 points lower than in 2017.
No. At 57% of the safe yield, Dharwad 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.
The first Census of Water Bodies counted 87 water bodies in Dharwad, including 10 ponds. 41 of them were not in use.
