Drains & Waterbodies
1. There are a total of
1011 water bodies in the
city, majority with the
BDO
2. Some are dry and
some have sewage
flowing in them from
adjoining abaadis
3. And, the drainage
from the larger
catchment of almost all
water bodies has been
disturbed due to ill-
planned development
over the years.

Sustained lowering of quality if life
Currently buried under
waste - sewage and solid
waste – the
environmental, social and
economic value of these
natural assets is
continually depleting,
giving rise to a crises that
impacts millions of Delhi’s
inhabitants – that of
sustained lowering of
quality of life

The site is almost fully enlosed by an existing boundary wall stopping flow of surface water from the larger catchment to the
waterbody. Punctures have been created in the wall along the abaadi edge to allow surface drains carrying grey water.
Encroachments exist on three locations on site.

Cleaning drains & water bodies
not only water….sludge, solid waste,
septage, other industrial effluent.
Restoring the ecological value
facilitate natural processes for
waterways first…then enhancing
biodiversity through ecological
landscapes that restore damaged
ecosystems and can add immense
ecological value for the city.
Creating Economic value
Communities turn itself around along
these new formed water oriented
corridors of amenity, giving rise to new
zones of growth and opportunities of
land value capture.
SEVEN STEPS
How to restore a drain / water body

A L S O F A C I L I T A T I N G S O C I A L N E E D S
Accommodating multiple uses
Chatt ghats
There is also an annually recurring need
to create chatt ghats along water
bodies and the river.
Recreational space for all
Parkway systems & Play areas
Walking / cycling facilities

T H E P R O P O S A L & P R I O R I T I E S
1. Trapping and cleaning of water to
rejuvenate the water body
2. Removal of historical sludge
3. Creation of enhanced capacity to hold
monsoon flows on the site
4. Restoration of the larger catchment of
the water body and its reconnection
5. Where appropriate, creation of ghats in
an environmentally friendly manner
6. Creation of ecologically designed easy
to maintain landscapes for public use
7. Putting in place management regimes
that are sustainable for the long term
and working with the community, a key
stakeholder

It is a special constructed wetland for the purpose of decentralized wastewater
treatment and conservation of fresh water bodies.
The system is based on the specific plants, such as Elephant grass (Pennisetumpurpurem),
Cattails (Typha sp.), Reeds (Phragmitessp.), Cannas pp. and Yellow flag iris (Iris pseudocorus),
normally found in natural wetlands with filtration and treatment capability.

Water Harvesting
1. The levels and grading of the
landscape is planned facilitate
water harvesting
2. The pathways and hard areas
would all be connected
through natural swales to catch
the runoff from the ground
3. The grasses around the Ghat
would clean the water from
the swale through bio
remediation
4. The Swales would all drain
towards rain garden which will
be low lying area.
5. The rain garden acts as primary
collection area of rain water
and recharges the ground
water.

Ecological Impact:
• Restore the flora and fauna- sighting of migratory birds, king fisher and ducks
• Enhanced Ground Water recharge with good quality of water.
• Clean water body resulting into eradication of disease
Social Impact:
• Connection of people & water body is established back.
• People now have a community space- recreation space & children play area
• A safe public space- All anti social elements & activities has cease to exist.
• Community Ownership- The Chatth Puja Samiti has ensured general upkeep of the water
body

Best Practice Documents
A Standard Operating Procedure (SOP) is a predefined
set of directives. In general terms, SOPs can be defined
as “a set of directives, covering those features of
operations that lend themselves to a definite or
standardized procedure”. Such procedures are
applicable unless prescribed otherwise in a particular
case. Thus, the flexibility necessary in special situations
is retained without the loss of its effectiveness.”
Standard Operating Policies and Procedures can be
effective catalysts to drive performance improvement
and improving organizational results (MoUD 2017).
The SOP for ‘Restoration & Management of
Existing Water Bodies’ can help the
relevant stakeholders to create such parks
keeping the rural setup in context.
