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.
Groundwater level in Shahdara
112%Over-exploited
This area pumps out more water than 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 55 points since 2017.

Extraction 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 |
|---|---|---|---|---|---|
| 2017 | 167.0% | 9.4 million m³ | 5.6 million m³ | Over-exploited | First assessment in this series. |
| 2020 | 108.4% | 14.5 million m³ | 13.4 million m³ | Over-exploited | Pumping up 54% (9 → 15 million m³). Safe limit up 139% (6 → 13 million m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. 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 | 108.6% | 20.4 million m³ | 18.8 million m³ | Over-exploited | Pumping up 41% (15 → 20 million m³). Safe limit up 40% (13 → 19 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 | 115.3% | 16.7 million m³ | 14.5 million m³ | Over-exploited | Pumping down 18% (20 → 17 million m³). Safe limit down 23% (19 → 15 million m³). Main reason: less water soaked back in, from weaker rain, less canal seepage or more paved ground. |
| 2024 | 116.8% | 17.0 million m³ | 14.5 million m³ | Over-exploited | Pumping up 2% (17 → 17 million m³). Safe limit up 0% (15 → 15 million m³). |
| 2025 | 112.2% | 16.7 million m³ | 14.9 million m³ | Over-exploited | Pumping down 2% (17 → 17 million m³). Safe limit up 3% (15 → 15 million m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

Ponds and lakes in Shahdara
16 of 16 water bodies (100%) 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
Most of the water here goes to homes and industry, so rooftop recharge and reuse make the biggest difference.
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.
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.
Meter borewells and fix leaks
Metered and registered borewells, leak repairs in supply lines and water-efficient fixtures cut pumping without anyone going short.
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.
Permeable paving and green cover
Porous pavers, unpaved tree pits and bioswales along roads let rain soak in instead of racing to the drain.
Frequently asked questions
What is the groundwater level in Shahdara?
In the 2025 Central Ground Water Board assessment, Shahdara (Delhi) pumped out 112% of the groundwater that can be safely taken out each year, which puts it in the "over-exploited" category. That is 55 points lower than in 2017.
Is groundwater in Shahdara over-exploited?
Yes. Shahdara takes out more groundwater than rain and other sources put back, so the water table keeps falling.
How can groundwater be recharged in Shahdara?
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 Shahdara?
The first Census of Water Bodies counted 16 water bodies in Shahdara, including 1 ponds. 16 of them were not in use.
