The Kushak - Barapullah Naalah that originates from the ridge and runs through the western fringes of Central Delhi, South Delhi and Nizammudin to join Yamuna at Sarai Kale Khan

With a width of 70 m. on an average this drain covers an area of 9.60 Ha

This drain collects the discharges of other internal, peripheral and trunk drains to further discharge its contents-1,25,000 Kld of domestic and industrial sewage into the Yamuna.

This important link road extending to 4.53 kms built over Delhiʼs historical drain - the Barapullah Nallah, starts from Ring Road near Sarai Kale Khan in East Delhi and ends at Jawaharlal Nehru Stadium in South Delhi.

50% of the sewage in this drain is untreated waste coming from cluster settlements

Proposals for revitalisation of the Nallahs by various organisations and people have included suggestions for improvement in quality of water and to activation of neighbouring areas. 01 To create a parallel channel for sewage. 02 To make STP’s at point of intersection of sub drains, after which treated water can be flown to open drain. 03 At points where there is more space can be made to eco-sensitive zones with treatment plants and water body. 04 Alternative routes or pedestrian walkways with jogging tracks can be made parallel to drain like barapullah elevated road, to make it more active and electric vehicles can be run on it connecting eco-sensitive zones and other places. 05 Planting more trees. 06 Area between sun dial and Yamuna can be made bio-diversity park with treated water of drain collected like in hauz khas and prevented to flow into Yamuna.

Delhi’s situation Today

ORDER\\ 18 MARCH 2014 We consider it most appropriate that the experts should suggest another possible mode by which the ecology and environment can be maintained, at the same time, methodology is provided for taking the sewage by a separate drain which may be through pipeline covered the drain or otherwise. Thus, we direct Secretary, Deptt. Of Public Health, Secretary, Deptt. Of Environment, NCT of Delhi, Prof. Gosain, Engineer-in-Chief, South Municipal Corporation of Delhi, CEO of DJB and Vice Chairman of DDA to constitute a committee. This Committee shall submit a report within two weeks from today before the Tribunal inter alia but primarily on the following:-

The ridge & river were important parts of all settlements of ancient and medieval Delhi.

Reservoirs were formed by encasing the natural terrain streams and were called Nallahs. They originated from ridge during rain and were used all year round for daily water uses.

Of birds and butterflies: Greenway why we should be worried Routes High pollution levels in the Yamuna, gradual disappearance of marshlands and shrinking of protected wildlife habitats such as the Okhla Bird Sanctuary on the river banks to a mere four square kilometre stretch of wetland have resulted in the dissapearing of important species of birds and butterflies.

Birds are considered to be a good indicator of the condition of the natural environment. The fact that a recent study by experts at Zoological Society of London (ZSL) and Yale University has identified 100 Evolutionary Distinct and Globally Endangered (EDGE) species worldwide shows that most of the habitats are under threat from unsustainable human activities.

Of these 15 are species from India.

When large habitats are fragmented into small isolated patches, food sources become scarcer for resident animals. Populations may then decline to the point that they are no longer able to benefit plants. As certain wild pollinators need undisturbed habitat for nesting, roosting, foraging and sometimes specific larval host plants, they are very susceptible to habitat degradation and fragmentation in particular. This means we could be looking at entire ecosystems crashing due to extinction of a few species.

This project looks at creating new habitats and magnifying the existing habitats of various species by increasing the size and connectivity of habitat patches along the Barapullah Nallah. The aim of this project is to attract existing species in greater number while also attracting new species, and making them a part of the city.

These paths along the nallah shall be developed as an extensive pedestrian network through the city while being an ecologically rich habitat for these birds and butterflies.

Ultimately we would like to see ecocorridors with pedestrian and bicycle access with controls to increase the pleasure of walking through the city and enjoying viewing of wildlife and bird watching.

Have ecosystems been revived before?

The Aravalli Biodiversity Park in Vasant Vihar in Delhi, 400 host plants have played a major role in supporting over 90 species of butterflies. The transition has taken time and effort. The project started in 2006, with just 14 species of butterflies.

The park started growing the host plants and some varieties of weeds that support butterflies. They also carefully collected caterpillars from the plants and shift them to a butterfly nursery where they are safe till they turn in to full-grown butterflies and can be released outside. A similar effort can be extended to the city.

This drain collects the discharges of other internal, peripheral and trunk drains to further discharge its contents-1,25,000 Kld of domestic and industrial sewage into the Yamuna.

This important link road extending to 4.53 kms built over Delhiʼs historical drain - the Barapullah Nallah, starts from Ring Road near Sarai Kale Khan in East Delhi and ends at Jawaharlal Nehru Stadium in South Delhi.

50% of the sewage in this drain is untreated waste coming from cluster settlements

Proposals for revitalisation of the Nallahs by various organisations and people have included suggestions for improvement in quality of water and to activation of neighbouring areas. 01 To create a parallel channel for sewage. 02 To make STP’s at point of intersection of sub drains, after which treated water can be flown to open drain. 03 At points where there is more space can be made to eco-sensitive zones with treatment plants and water body. 04 Alternative routes or pedestrian walkways with jogging tracks can be made parallel to drain like barapullah elevated road, to make it more active and electric vehicles can be run on it connecting eco-sensitive zones and other places. 05 Planting more trees. 06 Area between sun dial and Yamuna can be made bio-diversity park with treated water of drain collected like in hauz khas and prevented to flow into Yamuna.

These systems lost over the years and both river and water streams being the easy and cost free ways to discharge drain, are automatically converted to drainage channels, without giving a thought and these open and neglected drains leads to water crisis.

Delhi’s situation Today

ORDER\\ 18 MARCH 2014 We consider it most appropriate that the experts should suggest another possible mode by which the ecology and environment can be maintained, at the same time, methodology is provided for taking the sewage by a separate drain which may be through pipeline covered the drain or otherwise. Thus, we direct Secretary, Deptt. Of Public Health, Secretary, Deptt. Of Environment, NCT of Delhi, Prof. Gosain, Engineer-in-Chief, South Municipal Corporation of Delhi, CEO of DJB and Vice Chairman of DDA to constitute a committee. This Committee shall submit a report within two weeks from today before the Tribunal inter alia but primarily on the following:-

nallah nahi kaala

The ridge & river were important parts of all settlements of ancient and medieval Delhi.

Reservoirs were formed by encasing the natural terrain streams and were called Nallahs. They originated from ridge during rain and were used all year round for daily water uses.

Of birds and butterflies: Greenway why we should be worried Routes High pollution levels in the Yamuna, gradual disappearance of marshlands and shrinking of protected wildlife habitats such as the Okhla Bird Sanctuary on the river banks to a mere four square kilometre stretch of wetland have resulted in the dissapearing of important species of birds and butterflies.

Birds are considered to be a good indicator of the condition of the natural environment. The fact that a recent study by experts at Zoological Society of London (ZSL) and Yale University has identified 100 Evolutionary Distinct and Globally Endangered (EDGE) species worldwide shows that most of the habitats are under threat from unsustainable human activities.

Of these 15 are species from India.

When large habitats are fragmented into small isolated patches, food sources become scarcer for resident animals. Populations may then decline to the point that they are no longer able to benefit plants. As certain wild pollinators need undisturbed habitat for nesting, roosting, foraging and sometimes specific larval host plants, they are very susceptible to habitat degradation and fragmentation in particular. This means we could be looking at entire ecosystems crashing due to extinction of a few species.

This project looks at creating new habitats and magnifying the existing habitats of various species by increasing the size and connectivity of habitat patches along the Barapullah Nallah. The aim of this project is to attract existing species in greater number while also attracting new species, and making them a part of the city.

These paths along the nallah shall be developed as an extensive pedestrian network through the city while being an ecologically rich habitat for these birds and butterflies.

Ultimately we would like to see ecocorridors with pedestrian and bicycle access with controls to increase the pleasure of walking through the city and enjoying viewing of wildlife and bird watching.

Have ecosystems been revived before?

The Aravalli Biodiversity Park in Vasant Vihar in Delhi, 400 host plants have played a major role in supporting over 90 species of butterflies. The transition has taken time and effort. The project started in 2006, with just 14 species of butterflies.

The park started growing the host plants and some varieties of weeds that support butterflies. They also carefully collected caterpillars from the plants and shift them to a butterfly nursery where they are safe till they turn in to full-grown butterflies and can be released outside. A similar effort can be extended to the city.
