In 2014, of the 611 water bodies in Delhi, 274 were dead and remaining were in bad shape. Neela Hauz is a freshwater lake which was slowly dying due to the dumping of waste. [6] During ancient times it was the main source of water supply for the Rajput city of Qila Rai Pithora. [6] During ancient times, its basin was recharged by the wider dense forests of Sanjay Van and its overflow drained in to Yamuna. [6]
In 2014, the wetland was covered with water hyacinth and ridge was infested with the invasive species of prosopis juliflora (Vilayati Babul or Kikar of Mexican origin), which were planted in the 1920s by the Britisher colonisers to rehabilitate the wasteland. [7] [6] The silted up lake was encroached upon and raw sewage drained into it, causing concerned citizens to take an order from Delhi High Court to have it restored by the government. [6] After the restoration started in 2015, this biodiversity park was officially inaugurated in November 2016. [6]
Delhi has 7,884 hectares of fragmented forests which are deprived of wild animals due to the unplanned urbanisation. [5] In 2015, Delhi already had Aravalli Biodiversity Park and Yamuna Biodiversity Park. The Delhi Development Authority engaged the scientist of Delhi University to develop four more biodiversity parks in Delhi, including the Northern ridge biodiversity park (Kamla Nehru Ridge), Tilpath valley biodiversity park, Neelahauz biodiversity park and phase-2 of the Yamuna Biodiversity Park. [5]
In 2015, the Delhi Development Authority commenced the work to restore this as a biodiversity area. [1] [8] Lake was desilted, its banks landscaped, water supply was restored with the treated water from the Wastewater Treatment Plant, and native species of plants were reintroduced in 10 acres of the land surrounding the lake. [6] To improve the water quality before water enters the lake, the Constructed Wetland System (CWS) consists of zero energy input physical and biological processes, including 2 oxidation points and four filtration ponds/channels. [6] In first step of oxidation the organic sewage material is broken down by the atmospheric oxygen by microbes and in the second stage the aquatic plants treat the water. [6] Four channels have filters, such as pebbles and sand of varying size, to filter the water before it enters the lake. [6] After the CWS was operationalised, it is claimed that the Biochemical oxygen demand (BOD) fell from 40 to 4, phosphate 104 to 14, total dissolved solids from 600 to 298 and dissolved oxygen improved from 0 to 3.4. [6]
Independent water testing was carried out by the Delhi Jal Board in June 2019 as part of the investigation carried out by the Ground Water Monitoring Committee appointed by the NGT. It was found that the treated effluent did not meet permissible standards. [9] Prof. C.R. Babu was to improve the parameters of the effluent but up to November 2019 no published action has been taken.
Several ridges of Delhi are being restored to revive the native species including leopard, Indian rock python, jackals, neelgai, mongooses, porcupines, small Indian civet, gecko, Sirkeer malkoha cuckoo, nightjar, Indian paradise flycatcher. [7] [10]
15,000 native plants and shrubs of 75 species from 6 bio communities were planted in 2015–16. Slopes were stabilised by planting the grasses, such as chrysopogon, heteropogon and cenchrus ciliaris. Wetland has restocked with the phytoplankton, zooplankton, free floating and rooted aquatic plants. [6]
By 2016, the lake was home to over 70 bird species, including migratory birds. [6]
The Aravalli Range is a mountain range in Northern-Western India, running approximately 670 km (420 mi) in a south-west direction, starting near Delhi, passing through southern Haryana, Rajasthan, and ending in Ahmedabad Gujarat. The highest peak is Guru Shikhar on Mount Abu at 1,722 m (5,650 ft). The Aravalli Range is arguably the oldest geological feature on Earth, having its origin in the Proterozoic era.
Hauz Khas Complex in Hauz Khas, South Delhi houses a water tank, an Islamic seminary, a mosque, a tomb and pavilions built around an urbanized village with medieval history traced to the 13th century of Delhi Sultanate reign. It was part of Siri, the second medieval city of India of the Delhi Sultanate of Alauddin Khalji Dynasty (1296–1316). The etymology of the name Hauz Khas in Persian is derived from the words ‘Hauz’: "water tank" and ‘Khas’:"royal"- the "Royal tank". The large water tank or reservoir was first built by Allauddin Khilji to supply water to the inhabitants of Siri. The tank was de–silted during the reign of Firuz Shah Tughlaq (1351–88). Several buildings and tombs were built overlooking the water tank or lake. Firuz Shah's tomb pivots the L–shaped building complex which overlooks the tank.

Delhi Ridge, sometimes simply called The Ridge, is a ridge in the Northern Aravalli leopard wildlife corridor in the National Capital Territory of Delhi in India. It is a northern extension of the ancient Aravalli Range, some 1.5 billion years old. The ridge consists of quartzite rocks and extends from the southeast at Tughlaqabad, near the Bhatti mines, branching out in places and tapering off in the north near Wazirabad on the west bank of the river Yamuna, covering about 35 kilometres.
Badkhal Lake is a natural lake situated in Badkhal village near Faridabad, in the Indian state of Haryana, about 32 kilometers from the national capital of Delhi. Fringed by the hills of the Aravalli Range, this was a man-made embankment. Owing to unchecked mining in neighbouring areas, the lake began drying up two decades back and is now totally dried up. There are functional Haryana Tourism Corporation restaurants in the vicinity. A flower show is held every spring here. Its name is most probably derived from the Persian word beydakhal, which means free from interference. Close to Badkhal Lake is the Peacock Lake. It is a biodiversity area within the Northern Aravalli leopard wildlife corridor stretching from Sariska Tiger Reserve to Delhi.
Bandhwari is a village dominated by Gurjar community in Gurgaon district in the Indian state of Haryana. It is an important biodiversity area contiguous to Asola Bhatti Wildlife Sanctuary within the Northern Aravalli leopard wildlife corridor.

Sanjay Lake is an artificial lake developed by Delhi Development Authority (DDA) in Trilokpuri in East Delhi, India, adjoining Mayur Vihar II residential area. The lake is Spread over an area of approximately 17 hectares in the middle of a 69 hectares forest area, also known as Sanjay Lake Park.

A well-laid-out fitness track is very popular with walking-enthusiasts.
Water pollution is a major environmental issue in India. The largest source of water pollution in India is untreated sewage. Other sources of pollution include agricultural runoff and unregulated small-scale industry. Most rivers, lakes and surface water in India are polluted due to industries, untreated sewage and solid wastes. Although the average annual precipitation in India is about 4000 billion cubic metres, only about 1122 billion cubic metres of water resources are available for utilization due to lack of infrastructure. Much of this water is unsafe, because pollution degrades water quality. Water pollution severely limits the amount of water available to Indian consumers, its industry and its agriculture.
Damda reservoir in Sohna, near Gurugram city in Gurugram district in the Indian state of Haryana. Damdama Lake is a small lake in Haryana and was formed when a stone and earthen dam constructed by the British was commissioned for rain water harvesting in 1947. The lake, held by an embankment, is fed mainly by monsoon rain pouring into a trough at the base of the Aravali hills. The Lake greets visitors with a water level down to 20 ft (6.1 m). During monsoon the water level reaches up to 50 ft (15 m) - 70 ft (21 m).
