Recharge pits and shafts in open land
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.
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. Down 9 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 | 170.0% | 34.7 billion m³ | 20.4 billion m³ | Over-exploited | First assessment in this series. |
| 2013 | 149.0% | 34.8 billion m³ | 23.4 billion m³ | Over-exploited | Pumping up 0% (34.7 → 34.8 billion m³). Safe limit up 15% (20.4 → 23.4 billion m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
| 2017 | 165.8% | 35.8 billion m³ | 21.6 billion m³ | Over-exploited | Pumping up 3% (34.8 → 35.8 billion m³). Safe limit down 8% (23.4 → 21.6 billion m³). Main reason: less water soaked back in, from weaker rain, less canal seepage or more paved ground. CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 164.4% | 33.9 billion m³ | 20.6 billion m³ | Over-exploited | Pumping down 5% (35.8 → 33.9 billion m³). Safe limit down 5% (21.6 → 20.6 billion m³). |
| 2022 | 166.0% | 28.0 billion m³ | 17.1 billion m³ | Over-exploited | Pumping down 17% (33.9 → 28.0 billion m³). Safe limit down 17% (20.6 → 17.1 billion m³). |
| 2023 | 163.8% | 27.8 billion m³ | 17.0 billion m³ | Over-exploited | Pumping down 1% (28.0 → 27.8 billion m³). Safe limit down 1% (17.1 → 17.0 billion m³). |
| 2024 | 156.9% | 27.7 billion m³ | 17.6 billion m³ | Over-exploited | Pumping down 1% (27.8 → 27.7 billion m³). Safe limit up 4% (17.0 → 17.6 billion m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
| 2025 | 156.4% | 26.3 billion m³ | 16.8 billion m³ | Over-exploited | Pumping down 5% (27.7 → 26.3 billion m³). Safe limit down 5% (17.6 → 16.8 billion m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

8,332 of 16,012 water bodies (52%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

All about the ponds and lakes in Punjab, district by district
Most of the water here goes to homes and industry, so rooftop recharge and reuse make the biggest difference.
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.
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.
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.
Treated water from a sewage treatment plant can run flushing, gardens, cooling towers and construction, which today often draw on borewells.
On sloping or rocky land, small dams on seasonal streams and trenches along contours slow water down long enough for it to sink in.
Metered and registered borewells, leak repairs in supply lines and water-efficient fixtures cut pumping without anyone going short.
In the 2025 Central Ground Water Board assessment, Punjab pumped out 156% of the groundwater that can be safely taken out each year, which puts it in the "over-exploited" category. That is 9 points lower than in 2017.
Yes. Punjab 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 16,012 water bodies in Punjab, including 15,064 ponds. 8,332 of them were not in use.
Stage of extraction in 2025, most over-pumped first.
Yearly rain at Punjab, 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, Punjab has to put back or save 9.5 billion m³ a year. At 793 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.
