Ground Water Scenario of Delhi

Area (Sq.km)



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


The state is drained by river Yamuna

Rainfall (mm)

Average Annual rainfall: Safdarjung-712 mm

Total Districts

9 Districts / 27 Tehsils


 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.

Enactment of Ground Water Bill to regulate and control the development of ground water: 

The Delhi Water Board (Amendment) Bill, 2005 had been placed before the Assembly after which it was referred to a Select Committee of the Assembly. The Select Committee has rejected the amendment Bill and the report was adopted by the Assembly on 06.03.2006.

Inclusion of Roof Top Rain Water Harvesting (RTRWH) in building by laws:

Modified Building Bye-laws, 1983 to incorporate mandatory provision of roof top RWH in new building on plots of 100 sq.Mt or above. through storage of rain water runoff to recharge underground aquifer in NCT, Delhi exist.
To encourage rain water harvesting by Resident Welfare Associations/Group Housing Societies, the Govt. of NCT Delhi has launched a scheme for financial assistance in the Bhagidari concept, where 50% of the total cost of the project subject to a maximum of Rs. 50,000/- is being given to the RWAs as a grant if they adopt rain water harvesting.
