- Scarcity
What this assessment includes
Included in this result
- Groundwater: Before and after monsoon groundwater bands are available for 2023-24.
- Long-term availability: Both 2025 and 2050 published availability classifications are available.
Not included in this result
- Rainfall: Official rainfall context is not currently integrated into this JalWater result.
- Reservoir or supply context: Official reservoir or municipal-supply context is not currently integrated into this JalWater result.
- Water quality: Official water-quality evidence is not currently integrated into this JalWater result.
Scope
District-level evidence for Patna, Bihar. Reporting periods: 2023-24, 2025, 2050. Last checked 29 Jun 2026. Neighbourhood, building, borewell, tap-water, and current supply conditions may differ.
Confidence: Moderate
Moderate confidence. The displayed records match Patna, Bihar, and groundwater and long-term availability pairs are comparable within their published periods.
Confidence describes how well the evidence supports this result. It is not a safety, suitability, or city-quality rating.
Why this matters
The same official availability classification appears for both published periods. This does not establish a trend between them, so JalWater preserves the published bands without filling in the years between.
Groundwater depth does not show how much water is sustainably available, whether taps receive reliable supply, or whether the water is safe to drink.

2 to 5 mbgl2 to 5 mbglExact technical bands are shown as published in metres below ground level (mbgl). A lower depth means groundwater was recorded closer to the surface. JalWater does not convert ranges into point measurements, line charts, or trends.
2025 and 2050 outlook
Only the two official published periods are shown.
