Ground Water is a Precious National Resource - Preserve it, Protect it and Don't Pollute it.

State Profile 

Ground Water Scenario of Delhi (NCT)

Area (



  • Masudpur-Wazirabad Ridge
  • Older Alluvial Plain
  • Yamuna Flood Plain


The State is drained by river Yamuna

Rainfall (mm)

Average Annual rainfall: 611.8 mm

Total Districts

9 Districts


 The Ground water availability in the territory is controlled by the hydrogeological situation characterized by occurrence of alluvial formation and hard rocks such as quartzite. The hydrogeological set up and the following distinct physiographic units further influence the ground water occurrence: (1) Older Alluvial Plain on the eastern and western side of the ridge. (2) Yamuna Flood Plain deposits. (3) Isolated and nearly closed Chattarpur alluvial basin. (4) NNE-SSW trending Quartzite Ridge. The yield of tube wells ranges between 18-144 m3/hr in Yamuna Flood Plain aquifers. In Older Alluvium of eastern and western sides of the ridge, the yield of tube wells ranges between 12 to 36 m3/ hr. Tube wells constructed in Chattarpur alluvial  basin tapping the aquifers of both alluvium and weathered  and fractured quartzite yield about 9 to 27 m3 / hr.  Discharge of tube wells constructed in Quartzites varies from 6-15 m3 / hr.
