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 level in Palakkad

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. Up 0 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 | 61.0% | 484 million m³ | 795 million m³ | Safe | First assessment in this series. |
| 2013 | 55.0% | 353 million m³ | 638 million m³ | Safe | Pumping down 27% (484 → 353 million m³). Safe limit down 20% (795 → 638 million m³). Main reason: less water was pumped out, mostly for irrigation (355 → 219 million m³). |
| 2017 | 56.2% | 332 million m³ | 591 million m³ | Safe | Pumping down 6% (353 → 332 million m³). Safe limit down 7% (638 → 591 million m³). CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 56.7% | 331 million m³ | 584 million m³ | Safe | Pumping down 0% (332 → 331 million m³). Safe limit down 1% (591 → 584 million m³). |
| 2022 | 57.5% | 339 million m³ | 590 million m³ | Safe | Pumping up 2% (331 → 339 million m³). Safe limit up 1% (584 → 590 million m³). |
| 2023 | 59.8% | 339 million m³ | 568 million m³ | Safe | Pumping down 0% (339 → 339 million m³). Safe limit down 4% (590 → 568 million m³). |
| 2024 | 58.7% | 343 million m³ | 584 million m³ | Safe | Pumping up 1% (339 → 343 million m³). Safe limit up 3% (568 → 584 million m³). |
| 2025 | 56.3% | 313 million m³ | 557 million m³ | Safe | Pumping down 9% (343 → 313 million m³). Safe limit down 5% (584 → 557 million m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

Ponds and lakes in Palakkad
985 of 5,988 water bodies (16%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

What will fix it here
Groundwater here is in balance. Keeping it that way means recharging as the area builds up and paves over.
Revive village ponds and johads
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.
Rooftop rainwater recharge
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.
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.
Check dams and contour trenches
On sloping or rocky land, small dams on seasonal streams and trenches along contours slow water down long enough for it to sink in.
Treat and reuse wastewater
Treated water from a sewage treatment plant can run flushing, gardens, cooling towers and construction, which today often draw on borewells.
Frequently asked questions
What is the groundwater level in Palakkad?
In the 2025 Central Ground Water Board assessment, Palakkad (Kerala) pumped out 56% of the groundwater that can be safely taken out each year, which puts it in the "safe" category. That is 0 points higher than in 2017.
Is groundwater in Palakkad over-exploited?
No. At 56% of the safe yield, Palakkad is safe, though recharge is still needed as demand grows.
How can groundwater be recharged in Palakkad?
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.
How many ponds and lakes are there in Palakkad?
The first Census of Water Bodies counted 5,988 water bodies in Palakkad, including 5,795 ponds. 985 of them were not in use.
