City of Lakes is an initiative by the Delhi Government to raise Ground water levels and augment water supply through the creation of these robust water reserves
39 large & 381 smaller water bodies already rejuvenated, as of March 2024[1]
-- Tender for 25 more was in process
IMPACT: Water table rose around new/revived lakes as per survey by Centre for Science and Environment (CSE)[2]
~6 metres at Pappankalan
~4m at Nilothi
~3m at Najafgarh
¶ Detail Achievements till June 2023
26 lakes (across 20 sites) and 381 smaller water bodies have been rejuvenated
-- At least 11 sites have dedicated Walking tracks
¶ INNOVATIONS: Scientific Wetland with Active Biodigester (SWAB)[3][4]
The treatment of polluted water requires three — air, bacteria, and surface for bacterial growth
- Aeration equipment are installed to maintain high dissolved oxygen levels in the water
- The floated wetlands: a frugal innovative technology involves the plantation of wetland species such as Canna Indica and Cyperus papyrus. These plant species fix nitrogen and phosphorus, primary pollutants in wastewater.
- Their roots grow in water and act as a medium for bacterial growth. This bacteria acts as an agent and fixes pollutants such as ammonia while consuming oxygen.

¶ Why City of Lakes?
i. Main Objective: Sustainable Augmentation of Water Supply
- Delhi currently relies on fixed water share of rivers from its neighbouring states of Punjab, Haryana, and Uttar Pradesh to fulfil its water requirements
- With an ever-growing population and proportional increase in water demand, Delhi finds itself in a water deficit situation
- Need of sustainable solution to this pertaining water problem led to Delhi City of lakes
ii. Local recreational spots for public
iii. Beautification of local area
¶ Total Lakes/Water Bodies[20]
Delhi has 1045 Water bodies (including Lakes), according to Delhi Parks and Gardens Society NCT
- 65 water bodies are owned by Delhi Government
- 980 water bodies are directly/indirectly owned by Central Government**
Target - Phase 1:
A total of 600 lakes and waterbodies are being rejuvenated, while developing robust decentralised water infrastructure
