Environmental Impact Assessment (EIA) Notification, 2006 under the provisions of

the Environment (Protection) Act, 1986, which regulates development and their

expansion/modernization of 39 sectors/activities listed in the Schedule to the EIA

Notification, 2006.

• As per the EIA Notification 2006, and its amendments all the building

construction projects/area development projects and township projects comes under

schedule 8. and shall require prior environment clearance from State Environment

Impact Assessment Authority (SEIAA)/MoEF&CC before start

construction/expansion/modernization.

• The application for environmental clearance shall comprise submission of

Form 1, Form 1A, and Conceptual Plan along with necessary annexures in SEIAA.

The SEIAA/MoEF&CC shall base its decision on the recommendations of a state

expert appraisal committee (SEAC)/EAC.

Brief About Project and Project Proponent

• Netaji Subhas Institute of Technology (NSIT) was established in 1983 as Delhi

Institute of Technology (DIT) with an objective of meeting growing demand for

manpower in the emerging areas of Engineering and Technology, the then Delhi

Administration, with the approval of Ministry of Human Resources Development

(MHRD), Govt. of India,

• From 1983 till 1998, the Institute was operating from its old campus at the old

I.G. Block, Kashmere Gate, Delhi - 110006. The Institute was formally inaugurated in

its own new campus in Dwarka, New Delhi, 23rd

• This institutional area was developed before 2006, so environment clearance

was not required, but now new blocks are being planned to construct for academic

purposes so environment clearance is required. It is an autonomous Institute of the

January, 1997 by Sh. Atal Bihari

Vajpayee, the former Prime Minister of India. The Institute was renamed as "Netaji

Subhas Institute of Technology" (NSIT) in the year 1997 vide Gazette notification no.

Land Environment • Total land of 145 acre was allotted to director of training and technical education for setting up NSIT (formerly known as Delhi Institute of Technology) in 1989 by DDA.

Annexure 3: Land Ownership Documents

Topography • Physically the natural capital territory of Delhi can be divided into 3 segments - the

Yamuna flood plain, the Ridge and the Plain. The entire area of the national capital

territory of Delhi is categorized as Bangar or the plain. The land of the plain is mostly

fertile.

• The entire area of the site is monotonously flat. The project area possesses plain

terrain. Highest elevation levels is 219 meters & the lowest levels is 213 meters above

mean sea level.The project site is located in South West Delhi district which comprises of

three subdivisions namely: Delhi Cantonment, Najafgarh, and Vasant Vihar. The site is

bounded by sewak park residential area in its north, kartar nagar lie in the south direction.

Sector-15 is located in west of the site and gurpreet nagar is located to the east of the site.

• The project site has minimal variations in contour levels with the present topography

depicting the drainage towards the existing Najafgarh drain which is around 1.85 km from

the site.

Land Use As per the letter issued by Ministry of Urban Development (vide letter no. K-13011/7/2006-

DDIB Dated: 7.8.2006,), and DDA Dwarka comes under Zonal development plan, Zone-K.

Land use of the project site is public and semi public use.

Annexure 4-Zonal Development Plan Dwarka (K-II)

Physiography The study area lies in south west district of Delhi, which broadly forms the part of Delhi ridge

which is the northernmost extension of Aravalli Mountain. It consists of quartzite rocks and

extends from southern parts of the territory to western bank of Yamuna for about 35

kilometres. The alluvial formations overlying the quarzitic bedrock have different nature on

either side of the ridge. Ecologically, the Ridge acts a barrier between the Thar Desert and the

plains and slows down the movement of dust and wind from the desert. The ridge may be said

to enter Delhi from the south west. The eastern part of the ridge extends up to Okhla in the

South and disappears below Yamuna alluvium in the north east on the right bank of the river.


Conceptual Plan

Page

Geology and Seismicity The study area belonging to south-west district of Delhi is occupied by quartzite inter-bedded

with mica schist belonging to Delhi Super Group. The quartzite is grey to brownish grey,

massive-to-thinly bedded and structurally forms a coaxially refolded regional anticline

plunging towards north. The major planar structure strikes NE-SW with steep south easterly

dips. The thickness of alluvium on eastern side of ridge is generally greater than 300m. The

area is dissected by number of faults, fractures and shears, the trend of these varies from

NNE-SSW to ENE-WSW.As per the seismic zoning map of India (IS: 1893, Part-1, 2002),

the project site is located in the Zone IV, classified as MSK VIII i.e., area having high damage

risk zone. The design of all the proposed facilities in the project will take into account the

required seismic resistance.

Sewage Generation and Disposal During Construction Phase The quantity of sewage generation during the construction phase will be approx. 3.6 KLD.

Thus the sewage will be treated by providing small septic tanks, soak trenches and sulabh

shauchalaya type mobile toilets.

During Operational Phase Quantity of sewage generated during operational phase shall be approx. 232 KLD. Thus the

sewage will be treated through sewage treatment plant of capacity 278 KLD. The treated

sewage will be re used for flushing (106 KLD) greenbelt development (84 KLD) and for

HVAC and DG cooling (2+17 KLD).

The design of sewage network shall be done in accordance with the CPHEEO guideline, NBC

guidelines and reverent Indian Standards. Sewage generation is assumed to be 100% of

flushing water and 80% of domestic water.

The following parameters/ site conditions shall be kept in mind when designing the sewage,

Sludge and storm water drainage system.

• Natural slope of the area. • Layout of different facility in the complex; • Possibility of using complete or part of the existing sewage network; • Sub-soil water table; • Provision of Sewage lifting station; ( if required) • Provision of venting arrangement for manholes; • Construction of manholes & laying of pipes considering ground condition; • Termination of vent cowl at terrace level; • Provision of adequate slope for horizontal header in the under slung pipes especially for public toilets • Sewage flow starts with fractional capacity and builds up to full capacity in due course. An operational plan to meet this demand from a low flow to full flow will be part of the design.

A summary of board design parameters to be adopted for designing Sewage supply system is

given below.

Treatment Technology

Figure 5: Flow Diagram of Sewage Treatment Plant

The technology is based on attached growth aerobic treatment followed by clarification by a

tube settler. Lime will be dosed in for suppression of foaming tendencies. The clarified water

will be filtered in a pressure sand filter after dosing of coagulant (alum) for removal of

unsettled suspended impurities. This water will be passed through an activated carbon filter

for removal of organics. The filtered water from ACF is then chlorinated & stored in the

flushing tank. The attached growth fluidized aerobic bed reactor (FAB) process combines the

biological processes of attached & suspended growth. It combines submerged fixed film with

extended aeration for treatment of the waste water.

The waste water after screening is collected in an equalization tank. The equalization tank is

required for preventing surges in flow & facilitating equalization of characteristics over the

entire quantity of effluent in a given time. A provision for pre-aeration is made in the

equalization tank in order to ensure mixing & to prevent the sewage from going septic.

The equalized sewage is then pumped into the FAB reactor for biological processing. The

water enters the bottom of the reactor & flows up through the fixed film media which grossly


Conceptual Plan

Page

enhances the hydraulic retention time & provides a large surface area for growth of biological

micro – organisms. The FAB reactor is aerated by fine pore sub – surface diffusers which

provide the oxygen for organic removal. The synthetic media floats on the water & the air

agitation ensures good water to micro-organism contact.

The FAB treatment is an attached growth type biological treatment process where in, the

majority of biological activity takes place on the surface of the PVC media. Continuous

aeration ensures aerobic activity on the surface of the media. Micro – organisms attach

themselves on the media & grow into dense films of a viscous jelly like nature. Waste water

passes over this film with dissolved organics passing into the bio-film due to concentration

gradients within the film. Suspended particles & colloid may get retained on this sticky

surface where they are decomposed into soluble products. Oxygen from the aeration process

in the waste water provides oxygen for the aerobic reactions at the bio-film surface. Waste

products from the metabolic processes diffuse outward & get carried away by the waste water

or air currents through the voids of the media.

The aerated effluent passes into a tube deck settler for clarification. The theory of gravity tube

settler system is that the carrier fluid maintains laminar flow in the settling media at specified

maximum viscosity. These two parameters of a carrier fluid, flowing through a hydraulic

configuration, will determine the velocity gradients of the flow, the height of boundary layer

at the inclined surface and the residence time within the media.

The carrier fluid must be viscous Newtonian, exhibiting a Reynolds number of less than 1000

and preferably, a number under 400. The laminar flow, through the inclined tubes, will

produce velocity gradients sufficiently large to form an adequate boundary layer, where the

velocity of fluid approaches zero. Boundary layers are necessary in functioning tube settlers,

to allow suspended solids to separate from the viscous carrier fluid. Under gravitational

forces, they will settle to the hydraulic surface of the tube and subsequently from the clarifier

media.

Since the tubes are inclined at 60 degrees, solids settled on the tubes are continually

discharged down. This downward rolling action increases particle contact and hence further

agglomeration, which increases the sludge settle ability. Studies show that these agglomerated

sludge particles can have a settling rate in excess of ten times the settling rate of the individual

floc particles in the influent. These heavy agglomerated masses quickly slide down the 60

degree inclined tube and settle at the bottom of the tank.


Conceptual Plan

Page

22

Excess sludge from the bottom of the Tube settler shall be transferred into an adjoining

aerobic digester cum thickener tank. In this tank sludge shall be aerated. The air shall be shut

off periodically and supernatant water will be led back into the Equalization Tank. This way

the sludge shall be thickened and its volume shall be reduced. The thickened sludge will be

further solidified using a centrifuge or a filter press and the solid cakes will be used as manure

in horticulture.

The treated and disinfected water from the Chlorine Contact Tank will be passed through a

Multigrade Filter, an Activated Carbon Filter and a Softener and then stored in a Treated

Sewage Water Tank. Water from this tank will be used for the Cooling of DG system and for

horticulture and other recreational activity within the site.

Preventive measures to Avoid Leaching Treated sewage from Sewage Treatment Plant will be conveyed to Treated Sewage Tank

through pipelines. All the joints from piping system will be checked periodically and carrying

treated wastewater pipes will be laid in conduits wherever road crossings are expected. Thus

no leaching of treated sewage into nearby water courses shall take place. Supervisors will be

employed for overall operation & maintenance of water supply, waste water treatment and

other utility services

Rainwater Harvesting and Storm Water Drain A rainwater harvesting system comprises components of various stages -transporting

rainwater through pipes or drains, filtration, and recharging the ground water through tanks.

Percolation pits will be constructed for ground water recharge.

Runoff from the first spell of rain carries a relatively large amount of pollutants from the air

and catchments surface so the system will be provided with a filtration pit consisting of layers

of sand, gravel and pebbles of relevant sizes to remove impurities from the collected

rainwater.

Need For Rainwater Harvesting Surface water is inadequate to meet the daily demand and we have to depend on ground

water.

• Due to rapid urbanization, infiltration of rain water into the sub-soil has decreased drastically and recharging of ground water has diminished. • Rainwater harvesting prevents the flooding of low-lying areas in the site.

Rainwater Harvesting Network Rain water harvesting pits will be constructed all around the compound wall to collect rain

water. Excess storm water will be allowed to drain into the external storm drain.

Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak

hourly rainfall has been considered as 25 mm/hr. The recharge well of 4.5mtr dia and 3 mtr

depths will be constructed for recharging the water. The bottom of the recharge structure will

be kept 5 m above this level. At the bottom of the recharge pit, a filter media is provided to

avoid choking of the recharge bore.

The pit will be filled with rounded gravel 5 to 10 mm size. The sectional detail of the

proposed rain water recharge pit is provided in Figure 8

The path ways around the harvesting lines will be graded to facilitate drainage into trenches

proposed around the compound. Recharge wells/pits are envisaged along the path of the storm

water drains for rain water recharging & surplus water from the recharge wells/pits shall be

diverted to the storm water drainage network.

The collected storm water will be allowed to percolate to the sub-soil by suitably designed

percolation pits. The pits will be designed based on the soils percolation capability. The

subsoil water table is high in these areas and however harvesting pits with bores will be

provided.
