STP is proposed to use Moving Bed Bio Reactor (MBBR) process with UV for the treatment:
The treatment plant shall be designed with a capacity to handle 200 KLD of sullage for Phase I and
114 KLD of sullage for Phase II. Sewage and Wastewater will flow via gravity collection system
through a bar screen chamber to a sump chamber. A bar screen shall be provided at the inlet point in
the bar screen chamber and the sewage will flow through this bar screen into the sump. Bar screen
shall also be designed that it can be cleaned manually by going down to a platform in the chamber.
Two horizontal centrifugal pumps shall be provided in the sump to pump the collected sewage water
to the reactor. Air will be introduced in the sump through pipe grid, to avoid the sewage from
becoming septic.
Wastewater from the sump shall be lifted by means of effluent lifting pumps into Equalised Reactors
where BOD/COD reduction is achieved by virtue of aerobic microbial activity. Reactor would be
running in series. Oxygen required will be supplied through course bubble air diffusers.
The excess bio-solids washed in the biological process are separated in the downstream Clarifier/ Tube
Settler Tank. The clear supernatant will be collected in the Chlorine water tank cum filter feed tank.
The treated sewage is further pumped through filtration units. The sewage after CCT is disinfected and
shall meet the coliform norms of < 1000 counts with minimal dosage of sodium hypochlorite. The
coliform count in the treated effluent shall be almost nil.
The tertiary treatment consists of removing the residual suspended solid load, by filtering through
Dual Media Filter and passing the water through Activated Carbon Filter so that traces of BOD/COD
and excess chlorine are removed. The treated sewage shall be passed through Ultra Violet system (if
required) for water requirement for flushing purpose.
The biological sludge generated from the reactor which is settled in the Clarifier/Tube settler, is
pumped into sludge sump. Sludge shall be stored in the sludge holding tank for final dewatering and
disposal through screw pump and Centrifuge. The treated effluent from the Sewage Treatment Plant
shall be stored in Treated water storage tanks. The treated water is to be used for the horticulture and
flushing purpose. This treated shall be further softened and used for cooling tower make up.

2.9 RAINWATER HARVESTING
The storm water disposal system for the premises shall be self-sufficient to avoid any
collection/stagnation and flooding of water. The amount of storm water run-off depends upon many
factors such as intensity and duration of precipitation, characteristics of the tributary area and the time
required for such flow to reach the drains. The drains shall be located near the carriage way along
either side of the roads. Taking the advantage of road camber, the rainfall run off from roads shall flow
towards the drains. Storm water from various buildings shall be connected to adjacent drain by a pipe
through catch basins. Therefore, it has been calculated to provide 14 rainwater harvesting pits at
selected locations which will catch the maximum run-off from the area.

1) Since the existing topography is congenial to surface disposal, a network of storm water pipe
drains is planned adjacent to roads. All building roof water will be brought down through rain
water pipes.
2) Proposed storm water system consists of pipe drain, catch basins and seepage pits at regular
intervals for rain water harvesting and ground water recharging.
3) For basement parking, the rainwater from ramps will be collected in the basement storm water
storage tank. This water will be pumped out to the nearest external storm water drain.
4) The peak hourly rainfall of 45 mm/hr shall be considered for designing the storm water
drainage system.
Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak hourly
rainfall has been considered as 45 mm/hr. The recharge pit of 3 m length, 3 m width and 2.25 m depth
is constructed for recharging the water. Inside the recharge pit, a recharge bore is constructed having
adequate diameter and depth. The ground water level in the area is 30-40 meters bgl. The bottom of
the recharge structure will be kept 5 m above this level. At the bottom of the recharge well, a filter
media is provided to avoid choking of the recharge bore. Design specifications of the rain water
harvesting plan are as follows:
Catchments/roofs would be accessible for regular cleaning.
The roof will have smooth, hard and dense surface which is less likely to be damaged allowing
release of material into the water. Roof painting has been avoided since most paints contain
toxic substances and may peel off.
All gutter ends will be fitted with a wire mesh screen and a first flush device would be
installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags and
paper pieces will get arrested by the mesh at the terrace outlet and to prevent contamination by
ensuring that the runoff from the first 10-20 minutes of rainfall is flushed off.
No sewage or wastewater would be admitted into the system.
No wastewater from areas likely to have oil, grease, or other pollutants has been connected to
the system.
Calculations for storm water load in Phase-I:
Plot Area of Phase-I = 25,454.73 m2
Group Housing Colony

Gurgaon, Haryana Chapter II
M/s: EMAAR MGF Land Ltd. 24
Roof-top area = Ground Coverage of Pocket-A = 8,810 m2
Green Area = 10,708.66 m2
Green Area (without water body) = 7,870.8 m2
Paved Area = Plot Area – (Roof-top Area + Green area)
= 25,454.73 – (8,810 +10,708.66)
= 5,936.07 m2
Runoff Load
Roof-top Area = 8,810 × 0.045 × 0.80
= 317.16m3/hr
Green Area =7,870.8× 0.045 × 0.20
(Without water body) = 70.84 m3/hr
Paved Area = 5,936.07 × 0.045 × 0.70
= 186.986 m3/hr
Total Runoff Load = 317.16+ 70.84 + 186.986 m3/hr
= 574.986 m3/hr
Taking 15 minutes Retention Time, Total volume of storm water = 574.986/ 4
= 143.747 m3
Taking the effective length, width and depth of a Recharge pit 3 m, 3 m and 2.25 m respectively,
Volume of a single Recharge pit = l x b x h = 3 × 3 × 2.25 = 20.25 m3
Hence No. of pits required = 143.747 / 20.25 = 7.1 pits say 7 pits
Calculations for storm water load of Phase-II:
Plot Area of Phase-II= 20,436.62 m2
Roof-top area = Ground Coverage of Pocket-B= 9,348 m2
Green Area = 6318.5 m2
Paved Area = Plot Area – (Roof-top Area + Green area)
= 20,436.62 – (9,348 + 6318.5)

= 56.87 m3/hr
Paved Area = 4,770.12 × 0.045 × 0.70
= 150.259 m3/hr
Total Runoff Load = 336.528 + 56.87 +150.259 m3/hr
= 543.657 m3/hr
Taking 15 minutes Retention Time, Total volume of storm water = 543.657 / 4
= 135.914 m3
Taking the effective length, width and depth of a Recharge pit 3 m, 3 m and 2.25 m respectively,
Volume of a single Recharge pit = l x b x h = 3 × 3 × 2.25 = 20.25 m3
Hence No. of pits required = 135.914 / 20.25 = 6.7 Pits say 7 pits
As 1 pit/acre is required so, total 14 rain water harvesting pits will be required for 14.025 acre land.
Total of 14 Rain Water Harvesting pits are being proposed for artificial rain water recharge within the
project premises.

CHAPTER-3
DESCRIPTION OF ENVIRONMENT
3.1 INTRODUCTION
Information on the existing environmental status is essential for assessing the likely environmental
impacts of the project. In order to get an idea about the existing state of the environment, various
environmental attributes such as meteorology, air quality, water quality, soil quality, noise level, ecology
and socio-economic environment have been studied/ monitored.
3.2 STUDY PERIOD
Baseline environmental data generation for air, water, noise and soil quality monitoring around the
project site was conducted from March-May, 2015. Apart from field monitoring, additional data was
also collected from secondary sources like Irrigation Department, India Meteorological Department
(IMD), Central Ground Water Board, Geological Survey of India, State Ground Water Department,
State Pollution Control Board, Census of India and Local Forest Department, Non -Governmental
Agencies etc.
3.3 STUDY AREA
The site development area spreading across 56,757.16 m2 (14.025 acres) is a vacant land earmarked for
development of Group Housing Colony as per Gurgaon Manesar Urban Complex 2021. The probability
of impacts from the Group Housing Colony is generally within 2 kms. Field Monitoring has been carried
out beyond 2 km, in case of presence of sensitive receptors. The present report covers baseline
environmental data generated in the study area (10 km radius) all around the project site for land use and
the sample selection for monitoring are done within 5 km radius of the project site. Toposheet map
showing location of project site and surroundings within 10 km is enclosed as Annexure IV (b)
respectively. For biological studies, considering the ecological connectivity and widespread habitats of
wildlife, a 15 km radius around the project area has been considered for secondary data collection and
the map showing the same is attached as Annexure IV (c).
3.4 BASELINE MONITORING OF ENVIRONMENTAL COMPONENTS
In order to get an idea about the existing state of the environment, various environmental attributes such
as meteorology, air quality, water quality, soil quality, noise level, ecology and socio-economic
environment have been studied/monitored.

3.4.2 Air Environment
The prime objective of the baseline study with respect to ambient air quality is to establish the present
air quality and its conformity to National Ambient Air Quality Standards. This data has been further
used during impact assessment to predict the final air quality. This section describes the sampling
locations, frequency of sampling and methodology adopted for monitoring ambient air quality.
To quantify the impact of the project on the ambient air quality, it is necessary at first to evaluate the
existing ambient air quality of the area. The existing ambient air quality, in terms of Particulate Matter-
10(PM10), Particulate Matter-2.5 (PM2.5), Sulphur-dioxide (SO2), Oxides of Nitrogen (NO2), and Carbon
Monoxide (CO), has been measured through a planned field monitoring.
To assess the ambient air quality level, 5 (five) monitoring stations were set up. Table-3.2 gives location
of the ambient air quality monitoring stations. The location showing the air quality monitoring stations is
enclosed as Annexure VI.

AAQ5 Tigra NW 2.13
3.4.2.1 Monitoring Schedule
Ambient air quality monitoring was carried out twice a week with a frequency of 24 hours for 12 weeks.
3.4.2.2 Methods of Sampling and Analysis
Fine particulate Sampler APM MFC550 was used for monitoring Particulate Matter (PM2.5 and PM10);
gaseous pollutants like SO2, and NO2 was collected by Gaseous Pollutant Sampler APM 433 and CO
was monitored by Serinous 30 CO Analyser with NDIR detector.
3.4.2.3 Method for measurement of Particulate matter, SO2 & NO2
Method for measurement of Particulate Matter (PM10) in ambient air is done by Cyclonic Flow
Technique. Particles with aerodynamic diameter less than the cut-point of the inlet are collected by a
filter. Ambient air at the monitoring location is sucked through a cyclone. Coarse and non-reparable dust
is separated from the air stream by centrifugal forces acting on the solid particles and these particles fall
through the cyclone's conical hopper and get collected in the sampling cap placed at the bottom. The fine
dust (<10 microns) forming the particulate matter (PM10) passes the cyclone and is retained on the filter
paper. The mass of these particles is determined by the difference in filter weights prior to and after
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur, Chapter III
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 37
sampling. The concentration of PM10 in the designated size range is calculated by dividing the weight
gain of the filter by the volume of air sampled. A tapping is provided on the suction side of the blower to
provide suction for sampling air through a set of impingers for containing absorbing solutions for SO2
and NO2. Samples of gases are drawn at a flow rate of 0.2 liters per minute. The APM MFC 550 is used
for PM2.5. This system is a manual method for sampling fine particles (PM2.5 fraction) and is based on
Impactor designs standardized by USEPA for ambient air quality monitoring.
PM2.5 & PM10 have been estimated by gravimetric method. Improved West and Gaeke method (IS-5182
part-II, 1969) has been adopted for estimation of SO2 and Modified Jacobs-Hochheiser method (IS-5182
part-VI, 1975) has been adopted for the estimation of NO2.
3.4.2.4 Method for measurement of Carbon Monoxide – NDIR method
Instrument used: Ecotech Serinus 30 Carbon Monoxide
This analyser is used to measure CO in ambient air, in the range of 0-200 ppm (220 mg/m3) to a
sensitivity of 0.05 ppm 55µg/m3). The Serinus 30 combines the benefits of Microprocess control with
Non-Dispersive Infrared Spectrophotometry technology.CO Concentration is automatically corrected for
gas temperature and pressure changes.
3.4.2.5 Results and Discussions
The results of AAQ are given in details in Annexure VII and summarized in the tabular form. The
results when compared with National Ambient Air Quality Standards (NAAQS) of Central Pollution
Control Board (CPCB) for "Industrial, Residential, Rural and Other Areas" show that the average
values of ambient air quality parameters are well within the stipulated limit.
The results of ambient air quality monitoring are summarized in the Tables below:

3.4.3 Noise Levels
Noise is one of the most undesirable and unwanted by-products of our modern life style. It may not
seem as insidious or harmful as air and water pollutants but it affects human health and well-being and
can contribute to deterioration of human well-being in general and can cause neurological disturbances
and physiological damage to the hearing mechanism in particular. It is therefore, necessary to measure
both the quality as well as the quantity of noise in and around the site.
3.4.3.1 Methodology
The intensity of sound energy in the environment is measured in a logarithmic scale and is expressed in
a decibel, dB (A) scale. In a sophisticated type of sound level meter, an additional circuit (filters) is
provided, which modifies the received signal in such a way that it replicates the sound signal as received
by the human ear and the magnitude of sound level in this scale is denoted as dB (A). The sound levels
are expressed in dB (A) scale for the purpose of comparison of noise levels, which is universally
accepted by the international community.
Noise levels were measured using an Integrating sound level meter manufactured by Pulsar Instruments
Plc, Model NO. 91 (SL.No.B21625). It has an indicating mode of Lp and Leq. Keeping the mode in Lp

for few minutes and setting the corresponding range and the weighting network in “A” weighting set the
sound level meter was run for one hour time and Leq was measured at all locations.
The day noise levels have been monitored during 6.00 am to 10.00 pm and night noise levels, during
10.00 pm to 6.00 am at all the 5 locations, which covers residential areas, commercial area, industrial
area, Silence area if available within 10 km radius of the study area.
3.4.3.2 Sampling Locations
A preliminary survey was undertaken to identify the major noise generating sources in the area. The
noise survey was conducted to assess the background noise levels in different zones. Gazettes
Notification (S.O. 123(E)) of MoEF dated February 14, 2000 on ambient air quality standards has
different noise levels for different zones viz. project site, industrial, commercial, and residential and
silence zones. Five sampling locations were selected for the sampling of noise levels. The sampling

3.4.4 WATER ENVIRONMENT
3.4.4.1 Water Quality
Water quality assessment is one of the essential components of EIA study. Such assessment helps in
evaluating the existing health of water body and suggesting appropriate mitigation measures to minimize
the potential impact from development projects. Water quality of ground water has been studied in order
to assess water-uses in construction, drinking, cooling and horticulture purpose.
The water quality at the site and other locations within the 10 km impact zone was monitored during
March 2015- May 2015.
3.4.4.2 Sampling Frequency and Sampling Techniques
Parameters for analysis of water quality were selected based on the utility of the particular source of
water as per MoEF guidance. Hence quality of ground water was compared with IS: 10500: 1991
(Reaffirmed 1993 With Amendment NO -3 July 2010) for drinking purposes. Ground water quality was
analyzed for parameters as mentioned in the ‘Methods of Monitoring & Analysis published by CPCB (in
Annexure –IV of CPCB guidelines)’ and it was rated according to the CPCB Water Quality Criteria
against A, B, C, D & E class of water based on parameters identified in the criteria. Water samples were
collected as Grab water sample from sampling location in a 5 liter plastic jerrycan and 250 ml sterilized
clean glass/pet bottle for complete physico-chemical and bacteriological tests respectively. The samples

As per the standard practice, one sample from each station was taken each month in the study period.
Sampling was done by standard sampling technique as per the Standard Methods. Necessary precautions
were taken for preservation of samples. Location of Ground Water Sampling Sites is attached as
Annexure VI.
Table 3.8: Location of Water Sampling Sites
3.4.4.3 Result & Conclusion:
The results of analysis of ground water are given in Annexure VII.
The water quality in the impact zone was assessed through physico-chemical and bacteriological
analysis of ground water samples. The results have been compared with the drinking water quality
standards specified in IS: 10500. It was observed that all the physico chemical parameters and heavy
metals from surface and ground water samples are below stipulated drinking water standards.
All the ground water samples analyzed can be considered fit for drinking purpose in the absence of
alternate sources
Comparing the values of pH, DO, BOD and total coliforms with ‘Use based classification of ground
waters’ published by Central Pollution Control Board; it can be seen that the analyzed ground
waters can be compared with class ‘E’ and can be used as drinking water sources after conventional
treatment and disinfection. Bacteriological examination of ground water indicates the presence of total
coli forms, which may be due to human activities observed during the study period.
Rainwater Harvesting:
The main source of ground water recharging in the study area is rainwater, which infiltrates into the
ground through various litho logical units present in the study area. 30 number of rainwater harvesting
pits shall be installed to recharge the ground water. The runoff from the rooftop and storm water shall go
to the recharge pits.

Scheme for Ground Water Recharging
The rainwater will be diverted from the rooftop using rain water pipes to the surface / underground
drainage network. The entire building plot shall be sub divided for recharging structures.
It has been proposed to provide recharge pits for the desired purpose. The rainwater will be diverted into
the desilting tank to remove inorganic impurities and the outflow of the desilting tank will be taken into
the recharge well.
Desilting Tank
The desilting tanks are used to remove silt and other floating impurities from rainwater. Desilting tank is
like an ordinary container having provision for the inflow, outflow and overflow. Apart from removing
silt it holds the excess amount of water till it is soaked up by the recharge structure. The bottom of tank
will have unpaved surface (layers of coarse sand) to allow standing water to percolate into the soil.
Recharge well/pit
Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak hourly
rainfall has been considered as 45 mm/hr. The recharge pit of 3 m length, 3 m width and 2.25 m depth is
constructed for recharging the water. The ground water level in the area is 30-40 meters below ground
level. The bottom of the recharge structure will be kept 5 m above this level. At the bottom, a filter
media is provided to avoid choking of the recharge bore. Design specifications of the rain water
harvesting plan are as follows:
Catchments/roofs would be accessible for regular cleaning.
The roof will have smooth, hard and dense surface which is less likely to be damaged allowing
release of material into the water. Roof painting has been avoided since most paints contain toxic
substances and may peel off.
All gutter ends will be fitted with a wire mesh screen and a first flush device would be installed.
Most of the debris carried by the water from the rooftop like leaves, plastic bags and paper pieces will
get arrested by the mesh at the terrace outlet and to prevent contamination by ensuring that the runoff
from the first 10-20 minutes of rainfall is flushed off.
No sewage or sullage would be admitted into the system.
No sullage from areas likely to have oil, grease, or other pollutants has been connected to the
system.
It should be therefore concluded that there is no significant impact on surface water quality & hydrology
of the area. The proposed rainwater-harvesting scheme will stabilize the groundwater table in the area.
The schematic diagram of rainwater harvesting pit is shown in Figure-3.2.

3.4.5 LAND ENVIRONMENT
Land is the most vital resource for sustenance of life and degradations of land due to industrialization,
urbanization and population growth is a matter of concern. Therefore, it is necessary to establish the
existing land use pattern to optimize the land use as well as minimize degradation due to the
developmental activities. Also it is necessary to the landform of the project site and the quality of the
soil as soil erosion further deteriorates the quality of the land. Soil erosion can be prevented by
following methods:
Planting vegetation which stabilizes the soil and prevent erosion.
Applying a layer of mulch/fertilizer to the soil top which allows the soil to slowly soak up water,
protects against rain impact.
Using Geotextiles which helps in stabilizing soil.

Methodology
Detailed survey was conducted to evaluate faunal composition of the study area (core and buffer zone)
within the project area. Primary data like faunal composition was recorded during site visit and
secondary data was collected from the Forest department to get the correct picture of the study area. The
major portion of the study consists of agricultural field and human settlements which support wildlife
habitat insignificantly.
The survey methods used for faunal assessment are:
1. Walkthrough method
2. Direct Count Method- birds, mammals
The major part of the study area lies under agriculture field and human settlements which restricted the
wildlife habitat significantly. Most of the mammalian species reported in the study area are common
fox, and Indian hare. There is neither any wildlife sensitive area nor any corridor for the movement of
wildlife present in the study area. There are many small ponds present in the buffer zone of study area
which are the major attraction sites for avifauna. Common Maina, Kingfisher, Spotted dove, Pintail and
Pond Heron are some dominant bird species present in the study area. There is no information regarding
migratory movement of birds in the study area. As far as the reptiles community was concerned, Krait
and house lizard are reported from the study area.
3.8.3 Aquatic life
The Phytoplanktons in the lakes are basically dominated by filamentous forms. The dominant ones are
Chaetophora sp., Cladophora sp., Spirogyra sp. The Zooplanktons are basically dominated by
Crustaceans and Rotifers.
3.4.7. SOCIO ECONOMIC IMPACT ASSESSMENT
3.4.7.1 Background
Socio-Economic Impact Assessment (SEIA) refers to the systematic analysis of various social and
economic characteristics of the human beings living in a given geographical area during the period of
study. The geographical area is called Study Area or Impact Area. SEIA is carried out separately but
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur, Chapter III
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 66
concurrently with Environment Impact Assessment (EIA). The study area consists of core and buffer
area encircling the project area. The Socio-Economic Impact Assessment focuses on the likely effect of
the project on social and economic well-being of the community. The impact may be direct or indirect,
positive or negative.
In this part of the EIA report an attempt has been made to assess the Socio-Economic Impact of Group
Housing Colony Project located at Village Nangli Umarpur, sec-62, District Gurgaon in the state of
Haryana.
OBJECTIVES OF SEIA
The prime objective of the current study is to assess the likely impact of the proposed project on socio-
economic characteristics of people living in the study area. Further, it is to be established whether the
impact would be direct or indirect. Furthermore, it is to be examined whether the said impact would be
positive or negative. Lastly, it is to be comprehended if the impact is positive how long it would sustain
or if it is negative how soon the same could be eased.
SCOPE
The Scope of the study is as follows:
a) To collect baseline data of the study area
b) To comprehend socio-economic status of the people living in the study area.
c) To assess the probable impact of the project on social and economic aspects in the study area.
d) To evaluate the likely impact of the project on Quality of Life of the people living in the study area.
e) To ensure sustainability of the positive impact.
f) To suggest mitigation measures and agency responsible for taking action in case of adverse impact.
METHODOLOGY
For Socio-Economic Impact Assessment of the project, GRC India carries out systematic analysis of the
various socio-economic characteristics, both in terms of quality and quantity. Accordingly, both
qualitative and quantitative data was collected from secondary sources. The secondary data was
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur, Chapter III
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 67
collected from the published data/information of the Census Authority. Records of the state and district
administration were also referred to.
For collection of primary data, a sample survey was conducted in the study area. In each selected
habitation (village/town), a specified number of representative households were selected scientifically
for collection of information through face to face interview with head of the household or any
responsible member of the family.
Census-cum Sample Survey in the Core Area
As the likely impact of the project will be greatest in the core area and it diminishes progressively when
move away from the core area to the periphery of the study area, a Census-cum-Sample Survey was
conducted in the core area for the collection of socio-economic data.
It is treated as a Census Survey because all the villages/towns located in the core area were surveyed for
the collection of information. Further, in each village/town a household survey was conducted by
drawing representative samples from a list of households prepared. Since, collection of information from
all the households in a village/town is time consuming and expensive, the Sample Survey approach was
adopted for collection of information from the selected households in the villages/towns.
Sample Survey in the Buffer Area
In the buffer area, where the impact of the project progressively reduces with the distance from the
project area, Sample Survey was conducted for the collection of data.
Sample Design
Two-Stage Sampling Design was adopted in the study area. The First Stage Units were Census
villages/towns and the Ultimate Stage Units were households in the selected villages/towns.
Sample Size
The sample size at each level (village and household) was decided by using the formula = √ {(1.96
*σ)/Δ}; where n= Sample size, 1.96 is the Table Value of Confidence Limit, σ = Standard Deviation
and Δ = Degree of Precision.
Selection of First Stage Units (Villages/Towns)
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur, Chapter III
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 68
In buffer area the sample villages/towns were selected from the list of Census villages/towns by
adopting the method of Probability Proportional to Size (PPS), the size being number of households in
a given village/town.
Selection of Ultimate Stage Units (Households)
The sample households were selected from the list of households by adopting the method of Circular
Systematic Sampling. This method was adopted since the sampling frame i.e. the complete list of
households was readily available.
SURVEY INSTRUMENTS
The following Schedules/Questionnaires were developed for collection of Primary data:
Questionnaire-1A: Village Particulars
Questionnaire-1B: Town Particulars
Questionnaire-2: Household Particulars.
Each Questionnaire is divided into several blocks and there are both open-ended and closed-ended
questions.

4.1 INTRODUCTION
This chapter discusses identification and appraisal of various environmental impacts due to
Group Housing Colony. Generally, the environmental impacts can be categorized as either
primary or secondary. The development, construction and functional phase of the project
comprise various activities, each of which may have some impact on environmental parameter.
Various impacts during the development, construction and operation phase on the environmental
parameters have been studied to estimate the impact on environment. Group Housing Colony
will be constructed and developed gradually in the time span of 2-3 years (approx.). In
development phase, basic infrastructure facilities like internal road, sewerage system, storm
water drainage, street lighting etc. will be developed.
For proper evaluation and assessment of the environmental impacts due to development,
construction and functional phase of project understanding to the various activities associated
with Group Housing Colony is essential. Various activities related to the project would be
different, in terms of nature during the development, construction and functional phase.
The impact identification and prediction process aims to:
Identify potential source or cause of impact through out the life of project.
Characterize the potential impacts affecting a target or receptor (physical, human and
socio-economic).
Assess the potential of changing likely-hood of impact through Environmental
Management Plan (EMP).
Prediction of the impacts due to the development, construction and functional activities
encompass the developmental processes to be undertaken during construction and functional
phases.
For each category of environmental receptor (such as, ambient air quality, water quality, soils,
land, etc.) the potential impacts of activities during development & construction and functional
phases have been identified. Pollution sources & its characteristics, the potential impacts and
magnitude of the impacts have been assessed and discussed in detail in following sub sections.
In each case, cognizance has been taken to mitigation measures inherited in the development &
construction and functional phase.

Impact: Topography around the project is almost plain. Therefore, topography and
physiography of the area will not be affected during the construction and post construction phase
of the project. Hence, no significant impact is anticipated on the topography and physiographic
from project by M/s EMAAR MGF Land Ltd.
It is further proposed to maintain 30% of the total area as green through plantation of various
local and aesthetic species to improve the vegetation covers of the area.
Mitigation Measure: Since there is no significant impact on topography from the project, no
detailed mitigation measures are proposed. It is however proposed that apart from the proposed
plantation greens, turfing with local species will be carried out extensively.
4.5.2 Land Use Pattern
Impact: Group Housing Colony will be developed as per Gurgaon- Manesar Urban Complex
2021 which demarcates the project site as residential zone. Hence, no significant impact is
expected from the project which will be constructed after obtaining all necessary permissions.
4.5.3 Land Environment
Impact: At Group Housing Colony, soil would be excavated at project site for foundations of
residential, commercial and other purposes. During the disposal of redundant overburden, soil of
filling area would be covered and lost permanently.
The soil excavated during construction will be first temporarily stored in an area earmarked and
then shall be used to fill up low lying area in and around the project site and rest of the soil shall
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur Chapter IV
Sector-62, Gurgaon, Haryana
M/s: EMAAR MGF Land Ltd. 87
be transported by road to fill up low lying areas elsewhere. Proper drainage system shall be
provided to deal with the storm water in case of rain. The impact on soil during construction
phase will be marginal and reversible in the nature.
Mitigation: It is proposed to remove vegetative cover only from the specific site on which
construction is to take place and allowing minimal disturbance to the vegetation in adjacent
areas. Land clearing activities only confined to necessary areas. The top soil will be stripped
from constructional areas and stockpiled for later reuse in landscaping. The number, frequency
and area of movement of heavy machinery will also be restricted.
4.5.4 Water Environment
4.5.4.1 Ground water Quality
Impact: No hazardous chemical and material will be used in the development and construction
phase of Group Housing Colony. Debris and wastes generated during this phase will be collected
and disposed suitably. Therefore, possibility of contamination of ground water will be negligible.
Hence, no impact is anticipated on the ground water quality during the construction phase.
Mitigation: A well planned solid waste management plan will be followed during the
construction phase including timely collection, segregation and disposal as per legal
requirements.
4.5.4.2 Ground Water Hydrology
Ground Water Hydrology
Impact: In the area around the Group Housing Colony, rich aquifers are present. Water
requirement during construction phase will vary depending upon construction activities and will
be met by recycled water from STP. Water will be required for site preparation activities dust
settlement, consolidation, compaction and curing as well as building construction and drinking
water requirement. The requirement of construction water will not put sudden pressure on the
available ground water recourses of area. Therefore, impact on ground water resources will be
insignificant during construction of project.
Mitigation Measures: Although no significant impact is anticipated on the groundwater regime,
it is proposed to carry out the following to further minimize the demand on freshwater resources:
Curing water will be sprayed on concrete structures and free flow of water not allowed.
After liberal curing on the first day, all concrete structures will be painted with curing
chemical to save water to stop daily water curing hence save water.
Concrete structures will be covered with thick cloth/gunny bags and then water sprayed
on them to avoid water rebound and ensure sustained and complete curing.
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur Chapter IV
Sector-62, Gurgaon, Haryana
M/s: EMAAR MGF Land Ltd. 88
Ponds will be made using cement and sand mortar to avoid water flowing away from the
flat surface while curing.
Water ponding will be done on all sunken slabs. This will also highlight the importance
of having an impervious formwork.
4.5.5 Air Environment
Emissions Source: The potential sources of air emissions during the construction and
development phase of the project will be as follows:
Dust from earth works (during site clearance and preparation);
Emissions from power generator at site;
Emissions from the operation of construction equipment and machines;
emissions from vehicles running to site;
emissions during the unloading of material at the site;
emissions during mixing of cement with other building materials during development and
construction activities;
Air emissions other than dust arise from combustion of hydrocarbons. The pollutants of
concerns are NO2, SO2, CO, particulate etc.
Potential Impacts: Ambient air quality effects are normally assessed in relation to their
potential to cause;
Health deterioration and nuisance in local communities
Health deterioration amongst onsite workers
Assessment of the impacts from Dust Emissions: During the excavation of channels,
foundations, unloading of construction material, cement bags and mixing of cement with other
building materials such as brick and silica dust, wood dust, fugitive dust emissions may be
emitted at construction site. During construction, curtaining floors from all sides will be done to
prevent cement dust from becoming airborne. It may be noted that all the emissions will be in the
form of coarse particulate matter and settle down ultimately in closed vicinity of construction
site. Therefore, no significant impact is anticipated due to dust emission during development and
construction phase.
Assessment of the impact from Diesel Generators: Emissions from the D.G. Set during
construction phase may cause some localized impact on ambient air quality for short duration, as
it will be operated during power failure only. It may be noted that the D.G. Set power will be
used to operate construction equipment only if required. Adequate height of stacks and acoustic
erective will be provided to the D.G. Set as per guidelines of CPCB to facilitate the dispersion of
flue gases into the atmosphere.
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur Chapter IV
Sector-62, Gurgaon, Haryana
M/s: EMAAR MGF Land Ltd. 89
Mitigation Measures: It is proposed to provide adequate dust control systems in the form of
installation of batch plants, and loose material handling in covered sheds. Dust suppression
system is also to be provided where necessary. Provision for treatment of DG Flue Gas emissions
in a scrubber will be considered. It is further proposed to cover scaffolding, hosing down road
surfaces and cleaning of vehicles especially during the dry season. Avenue and curtain plantation
on the internal roads and peripheral plantation around the site will also be developed.
4.5.6 Noise Environment
During the construction phase of project, noise will be generated from the various sources. Some
major sources of noise generation at project site are listed here under:
Generation of noise during movement of vehicles carrying materials and loading &
unloading activities.
Generation of noise from excavation machines, concrete mixer and other construction
machines,
Generation of noise during the operation of D.G. Sets
Generation of noise during concreting, hammering, etc.
All the above-mentioned sources of development and construction activities at Group Housing
Colony would be intermittent and experienced occasionally. It may also be noted that the most
of the construction activities would be carried out only during the daytime.
The expected noise levels from various activities are given hereunder:
From vehicles bringing materials to the site 70 dB (A)
D.G. Set 85 dB (A)
Excavation 80 dB (A)
Concrete Mixtures 80 dB (A)
Hammering 85 dB (A)
Resultant Noise Level:
The combined effect of above sources can be determined as per the following equation:
Lp (total) = 10 log (10(Lpl/10)
+ 10(Lp2/10)
+ 10(Lp3/10)
+……..) ……. (1)
Where: Lp1, Lp2 and Lp3 are noise pressure level at a point due to different sources in dB (A). The
resultant maximum noise level for the above sources as calculated using equation (1) is 89.3 dB
(A).
For an approximate estimation of dispersion of noise in the ambient air from the sources point, a
standard mathematical model for sound wave propagation is used. The sound level generated by
noise source decrease with increasing distance from the source due to wave divergence. An
additional decrease in sound pressure level from the source is expected due to atmospheric effect
or its interaction with objects in the transmission path.
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur Chapter IV
Sector-62, Gurgaon, Haryana
M/s: EMAAR MGF Land Ltd. 90
For hemispherical sound wave propagation through homogenous loss of free medium, noise
levels at various locations can be calculated due to different sources using model based on the
first principles as per the following, equation:
Lp2 = Lp1 -20 log (r2) – 8 ………. ( 2 )
Where: Lp2 and Lp1 – Sound Pressure Level (SPLs) at points located at sources and at distance
of r2 from the source respectively in dB (A).
Assuming no environmental attenuation factors, noise modeling has been done, which shows
that noise level will be mingle with baseline noise level with in short distance. Noise modeling
results for construction phase have been given in Table 4.4.

The noise produced during, development and construction phase will have temporary impacts on
the existing, ambient noise levels at project site but restricted to small distance (maximum up to
4.3 km) and only during daytime. Therefore, the impact of noise levels on surrounding area will
be insignificant during the development and construction phase.
Mitigation: To minimize impacts of noise generation from construction activities, the workers
will be provided with ear muffs and other protection devices. D.G. Sets with proper acoustic
enclosure for controlling noise would be installed.
4.5.7 Terrestrial Ecology
Impact: There is no loss of forestland due to the construction of the Residential Group Housing
Colony. No tree felling is involved, as the site is devoid of vegetation.
Birds and other domesticated biodiversity observed near the project site are common and already
adapted to thrive in human - colonized habitats. The project will not have any major negative
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur Chapter IV
Sector-62, Gurgaon, Haryana
M/s: EMAAR MGF Land Ltd. 91
ecological impact. There is no forest near the project site and therefore there will be no effect on
the ecology of the area.
Mitigation Measures: However, it is to develop extensive green areas in the project site to
improve the aesthetics of the area which will also help in reduction of air pollution, noise
pollution and provide suitable habitat for local birds and animal species.
4.5.8 Economic Impacts
Impact: Relatively long-lived economic impacts of the development and construction phase are
likely to be experienced in local area for the duration of construction phase of 2 years as workers
make everyday purchases from local traders in near by areas. This is likely to give a short-lived
stimulus to the traders that may disappear as soon as the construction is complete. Noticeable,
flow-on economic impacts will be experienced in other sectors of economy as a result of
purchase of construction materials and the payment of wages and salaries to the personnel
engaged in the development and construction of colony. Once the development and construction
of residential project will complete, there will be some long-term positive impact on the
economic structure of the area. People in the area will get direct and indirect employment
opportunities and other benefits from the residents of Group Housing Colony. Therefore, overall
positive impact is anticipated on economy of the area due to development and construction
activity of the Group Housing Colony.
4.5.9 Socio-Economic
During the development and construction of Group Housing Colony, about 150 to 200 skilled
and semiskilled and unskilled workers per day will get direct employment opportunity, which
will have beneficial impact on the local people and improve socio-economic conditions of the
area.
4.5.10 Construction Camp
Impact: During the development and construction phase, most of the laborers will be from local
areas as Group Housing Colony will be developed gradually in the time span of about 2 years.
Therefore, laborer camps will be constructed to accommodate the laborers at the project site.
This may lead to sanitation problems in the absence of adequate facilities.
Mitigation: Suitable measures will be taken at the construction camps to mitigate anticipated
impacts due to temporary accommodation of laborers such as provision of clean drinking water,
adequate toilet facilities, water and solid waste disposal system.
Other safety precautions to be maintained at work site including provision of PPEs, guarding of
dangerous machine parts, maintenance of equipments as hoists and lifts etc, and adequate
provision of different types of fire extinguishers will be made. All applicable rules and
regulations pertaining to workplace health and welfare of workers will be adhered to.

M/s: EMAAR MGF Land Ltd. 92
4.5.11 Solid Waste Management
Impact: The construction and demolition waste includes debris, concrete (often recycled and
reused at the site), steel and other metals, pallets, packaging and paper products, fluorescent
tubes, wood beams, joists, studs, baseboards, cabinets and cupboards, railings, brick, doors and
casings, interior windows, bathroom fixtures, light fixtures, ceiling grid and tile, furnishings,
replant trees, shrubs. All wastes generated during the construction phase shall be collected and
segregated for disposal as per the standard practice.
During the development and construction phase, some amount of debris, cuttings of construction
materials may be observed at construction site. However, the quantity of these waste materials
would be very small and limited up to the construction site only. There will be no contamination
due to this waste as it will be collected time to time during construction phase and disposed
accordingly.
Mitigation Measures: After due waste segregation, recyclable wastes will be sold off to scrap
dealers and vendors, while inert wastes will be disposed off in landfills. Hazardous wastes will
be disposed off as per the provisions of the Hazardous Wastes (Management & Handling Rules,
1989).
4.5.12 Transport Linkage and Traffic
Impact: During development and construction phase, construction labour and construction
materials bringing vehicles will approach the project site. The residential colony is well
connected to neighborhood, where public transport facility, like, buses and minibuses are easily
available in the area as transport linkage. During construction phase, some impact is anticipated
on the transport linkage of the area, however increase in traffic will not adversely affect the local
traffic pattern since the site is well connected by broad road and present traffic load on these road
are not significant.
Mitigation: Through careful planning, the movement of the heavy vehicles will be scheduled to
reduce load on existing traffic such that the peak hours are avoided. It shall also be ensured that
all the vehicles to the site will be provided with Parking space such that there is no waiting time
along the access roads.
4.6 ASSESSMENT OF THE ENVIRONMENTAL IMPACTS DURING OPERATION
PHASE
4.6.1 Land Environment
Impact: During the operation phase of the project, the soil may get polluted/ contaminated from
littering of various kinds of wastes generated within the site such as food items, paper, wood
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur Chapter IV
Sector-62, Gurgaon, Haryana
M/s: EMAAR MGF Land Ltd. 93
pieces, paints, pesticides, oil & grease etc. However, owing to the proposed solid waste
management system, no significant impact is anticipated.
Mitigation Measures: To ensure against any chances of soil pollution, it is imperative to
establish a well planned solid waste collection system covering all areas of the project site apart
from door to door for the residential units. An identified area shall be designated for storage and
segregation of the wastes which will be treated/ disposed as per their characteristics.
4.6.2 Water environment
4.6.2.1 Surface water hydrology
Impact: During the post construction phase, no water will be taken from surface water bodies in
the area. Further, adequate drainage will be provided at the project site to channelize the storm
water for rainwater harvesting.
The sewage effluents generated from the project will be collected through the sewer line network
provided in the project site for treatment in the Sewage Treatment Plant (STP), and the treated
wastewater reused within the site thereafter. Therefore, impact on the surface water hydrology
will be insignificant during the post construction phase.
Mitigation: It is proposed to provide rainwater harvesting across the project site. The roof tops
of buildings will also be connected to the rainwater collection system. This will not only reduce
the pressure of stormwater management system of the city but also recharge groundwater.
4.6.2.2 Ground water hydrology
Impact: During post construction phase, the total water requirement of the Group Housing
Colony is approx. 482 KLD out of which total domestic water requirement is 360 KLD. The
fresh water requirement is approx. 257 KLD (which is 70% of the domestic water demand). The
water will be supplied by HUDA. Therefore, no significant impact is anticipated on ground water
resources due to project.
Mitigation Measures: The rainwater harvesting will recharge groundwater aquifers from the
open areas as well as roof top of the buildings. Treated wastewater from the site will be recycled
for landscaping and flushing to further reduce demand on freshwater resources.
Water meters conforming to ISO standards should be installed at the inlet point of water uptake
and at the discharge point to monitor the daily water consumption. To further lower the water
consumption, options of Low flow flushing systems, sensor based fixtures, waterless urinals, and
tap aerators etc will be explored.

4.6.2.3 Surface Water Quality
Impact: The sewage effluent generated from the Group Housing Colony will be collected
through the sewer line network provided in project and treated in Sewage Treatment Plants
(STP’s) of capacity STP of 240 & 135 KLD.
Mitigation Measures: As no significant impact is anticipated on the water bodies of the region,
no mitigation measures are suggested.
4.6.2.4 Ground Water Quality
Impact: The storm water from the site will be used for recharging groundwater resources after
adequate treatment of the storm water through oil, grease traps and filtration. The wastewater
from the site is proposed to be used for landscaping only after adequate treatment in Sewage
Treatment plant. Hence, no adverse impact is anticipated on the groundwater quality form the
project.
Mitigation Measures: The Group Housing Colony will be well maintained. Solid waste
management practices will be adopted and followed to prevent groundwater pollution through
leaching.
4.6.3 Air Environment
Impact: During the post construction phase, cars, scooter/motorcycle will be owned by the
population of Group Housing Colony. Vehicular emissions will be major source of air pollution
in addition to DG set. Quantum and dispersion of pollutants form vehicular emission will depend
upon the following:
Emission of pollutants from additional traffic on the roads due to the projects,
Meteorological conditions.
Emission sources from D.G. Sets.
From vehicular emissions, PM, NO2, SO2 and CO is pollutants of primary concern released from
traffic movement & DG sets. The dispersion of vehicular emissions would be confined within
300 m from the road and from the line source model it is observed that concentration will
decrease with the increase in distance from road. It is anticipated that the contribution of
vehicular emissions in ambient air quality will be marginal but well within the stipulated
National Ambient.
7 nos. of D.G. sets of total capacity 2,780 KVA (2 X 500 KVA + 2 X 320 KVA+3X 380 KVA)
will be provided for back up electricity supply during power failure. This will cause emission of
PM, SO2, NO2 and CO. However, since the D.G. sets will be operational only during power
failure and low sulphur diesel will be used; therefore, pollutants incremental load in the ambient
air environment will be expected to be minimal. However, an adequate stack height of D.G. Sets
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur Chapter IV
Sector-62, Gurgaon, Haryana
M/s: EMAAR MGF Land Ltd. 95
will be provided as per the stipulated guidelines of Central Pollution Control Board (CPCB) to
facilitate proper dispersion of exhaust gases as given below considering height of the building:
ISCST3 dispersion model was used to predict GLC caused by a single point source (3 stacks)
at each receptor of 100 m x 100 m of grid network covering total area of 2000 m x 2000m
around the proposed source with stack & emission values and 1-hourly meteorological data. It
was observed that SO2, NO2, Co and PM were significant pollutants released from the fuel of
the D.G. sets. Emission of PM, CO and SO2 were found insignificant with low values compared
to NO2. In this proposed project, NO2 was the worst affected pollutant released into the
atmosphere (Table 4.5). 24-h GLC were predicted for SO2, NO2, CO and PM but isopleth of
NO2 is only presented in the report as GLC of other pollutants were lower under similar
meteorological conditions.

Mitigation Measures: In the group housing colony, green belt will be developed inside the
premises of the project site and along the internal road, which will work as barrier for the
movement of pollutants and help in pollution control.
4.6.4 Noise Environment
Impact: The main sources of noise from the project are running of D.G. Sets and vehicular
traffic. D.G. Sets will provide emergency electricity supply during power failure. This will be
intermittent and for short durations. The vehicles playing within the site will be mainly of the
residents and are hence not expected to cause unnecessary noise. Hence, during this phase, no
major impact on noise environment is anticipated.
Mitigation Measures: D.G. Sets will be fitted in acoustic enclosures to control the noise
generated within 25 dB (A) insertion loss or for meeting the ambient noise standard whichever is
on higher side as per E (P) Act, GSR 371 (E) and its amendments. Adequate personnel protective
Group Housing Colony EIA/EMP Report

equipment (PPE) will be provided to the personnel engaged in D.G. Set room. The traffic noise
will diminish within a short distance from the source of origin. Honking within the site will be
discouraged. Proposed rows of plantation will further restrict the noise on other side of the
plantation i.e. outside the boundary.
4.6.5 Terrestrial Ecology
Impact: The project proposes 17,027.16 m2 of green area (30% of Total plot area) that will be
planted with local species with aesthetic appeal that will attract local bird and insect species. As
against the existing barren stretch of land, the project will add to the greenery and beauty of the
region.
Mitigation Measures: Various kinds of plantation such as curtain, avenue and ornamental
plantation and lawns will be started during the construction phase itself and maintained during
the operation phase. Open space and Parks will be fenced through the grasses and ornamental
plants. Local and low water demanding plants that will also be effective as sinks for various
pollutants and attract birds will be grown in the site that will contribute in positive to the local
ecology.
4.6.6 Socio-economic Impact
Impact: During operational phase of Group Housing Colony, more than 200 persons will get
employment opportunities as staff for management, maintenance and security. As an estimate,
during post construction phase, more than 300 persons will get marginal employment
opportunities from the residents of Group Housing Colony project who would work as domestic
helpers. This will help in improving the quality of life of economically weaker sections of the
local area.
Mitigation Measures: To further improve the socio-economic conditions of the area, it may be
proposed to employ mainly local people as workers. Much of the maintenance arrangements may
also be made with local companies and purchase of new parts from the local market.
4.6.7 Transport Linkage and Traffic
Impact: The vehicle from the project will increase car and two wheeler traffic load along the
road during peak hours. However, since present load is lean, increase in traffic load may not lead
to traffic congestion problem.
Mitigation Measures: As per the conceptual plan, the entrance to the project site is proposed
along the road. The available width provided shall have sufficient merging space for the vehicles
while meeting the road.

4.6.8 Energy Resources
Impact: During the operation phase of the project, electric supply will be provided from
Dakshin Haryana Bijli Vitran Nigam. The proponents will make arrangements for meeting any
electricity shortage for the project. Therefore, energy resources of the region will not be affected
significantly.
Mitigation Measures: To promote energy conservation, it is proposed to provide the buildings
with low energy consuming fixtures maximize availability of natural light.

CHAPTER-5
ANALYSIS OF ALTERNATIVES
5.1 INTRODUCTION
This chapter discusses the assessment of various options that may be available for different
components of the project in terms of environmental suitability. Lately, there are a number of
options available for the use of building materials, means of energy conservation and methods of
transportation. The various applicable options are thus evaluated for their suitability to project
and environment.
5.2 BUILDING MATERIALS
The choice of building materials plays an important role in terms of energy efficiency of the
building. The manufacturing of building materials should also be assessed to ensure the use of
environment friendly and recycled/recyclable construction materials.
5.2.1 Wall
Conventionally, sun burnt clay bricks are cemented in the construction of walls. The strength of
these construction materials cannot be compromised which will otherwise pose a threat to the life
and property of the occupants. However, presently, materials with similar properties are easily
available that are made of waste products, thereby reducing the waste burden and conserving
natural resources. Thus, the project proposes the use of the following for walls:
Brick and block products with waste and recycled contents such as fly ash (15 to 35%),
blast furnace slag (20 to 25%), sewage sludge, waste wood fibre etc.
Fly ash based lightweight aerated concrete blocks (CLC blocks) – flyash being a waste
product of thermal power plant poses the challenge of disposal. Hazardous in powder
form, it is rendered harmless when moulded as bricks. Fly ash-based lightweight aerated
concrete blocks are manufactured for walling and roofing purposes by mixing fly ash,
quick lime, or cement and gypsum with a foaming agent like aluminium powder
Fal-G products – are manufactured by use of two waste products being fly ash, calcined
gypsum (a byproduct of phosphogypsum or natural gypsum) along with lime.
Perforated bricks
Materials proposed for use in the wall openings such as doors and windows include:
Precast thin lintels, use of ferrocement-sunshade cum lintel etc.
Renewable timber
Steel manufactured from recycled content
Aluminum manufactured from verified recycled content
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur, Chapter V
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 102
Saw dust based doors and window frames
Ferrocement shutters, PVC doors and windows, Rice husk boards, Natural fibre-
reinforced
Polymer composite door panels
The finishing for the openings will be by the use of Fly ash, Ceramic tiles, Terrazzo
floors.
5.2.2 Roof
The conventional material used for roofing is RCC, as it is suitable for longer spans. The
constituents of RCC, i.e. cement, sand, aggregate and steel are energy intensive materials and
high embodied energy content.
Alternately, it is proposed to use lightweight synthetic aggregates such as fly ash based
aggregates, which is suitable for manufacture of brick, blocks, and is good substitute for clinker
and natural aggregates. When pre-cast/aerated cellular concrete walling blocks and roofing slabs
are used in multi- storied structures, they reduce the weight, resulting in a more economical
design. They have high rating to fire resistance and provide better insulation and thus improved
energy efficiency. These are manufactured by the aerated cellular concrete manufacturing
process.
5.2.3 Superstructure
Structural frame of building comprises of footing, columns, beams and lintels, over which the
envelope of building is supported. A variety of metals are used in buildings, but the major
building material used structurally is steel. Steel has a high-embodied energy and recyclable
content, as well as scrap value. Aluminum forms the second most common material used for
roofing sheets, window frames, and cladding systems, which has the highest recyclable content.
Hence, bulk of the metal needs for the building shall be met by steel and aluminum.
Problem with RCC. The choice of cement will be:
Use of fly ash and/or blast furnace slag concrete: The amount of cement used in
concrete can be reduced by replacing a portion of the cement with coal fly ash (waste
material from coal burning power plants) and/or GGBF (ground granulated blast furnace)
slag in conventional mixes.
Recycled aggregates: Recycled aggregates include crushed concrete, brick, glass, or
other masonry waste can also be used in conventional mixes
Lightweight concrete: Aluminum powder when added to lime reacts and form hydrogen
bubbles, and a lightweight cementitious material is formed which could be used in
conventional mixes.

5.2.4 Roads and open spaces
Roads and open spaces consist of compound walls, grills, roads, sidewalks, parking lots, drains,
curbs, landscaped areas, street furniture, tree covers, and flowerbeds.
In line with environment friendly design it is proposed to provide:
Permeable paving- Permeable (porous) paving will be provided to control surface water
runoff by allowing storm water to infiltrate the soil and return to the ground water. The
traffic areas will however continue to be impermeable.
Gravel/crusher fines- Loose aggregate materials from masonry wastes will be used to
cover pedestrian surfaces.
Use of grass pavers on the road, parking and pedestrian areas to reduce the heat island
effect.
Use of steel in fencing, grills, tree covers, and benches and even in streetlights will be
replaced by bamboo in the parks and green landscaped areas.
5.3 NATURAL HAZARD PRONE AREAS
The project will be situated in earthquake risk area (Seismic zone- IV). Special attention is thus
given to the structural design of foundation, elements of masonry, timber, plain concrete,
reinforced concrete, pre-stressed concrete, and structural steel. All applicable guidelines will also
be followed in this regard to ensure safety of the building and its residents.
5.4 ENVIRONMENT FRIENDLY DEVELOPMENT
Without compromising on the safety and comfort of the occupants, care will be taken to achieve
an energy efficient, water conscious project the benefits of which will be enjoyed in monetary
terms by the residents and other intangible benefits will result for the society at large. This will
be achieved by:
a. Minimal disturbance to landscapes and site condition
The project aims to integrate the new development with the local existing surroundings. Efforts
are made to minimize on-site tree cutting by careful and detailed layout planning. Tree felling
shall be undertaken only after receiving requisite permissions and under strict supervision. The
original landscape of the site has also been integrated with the design of the group housing
colony such that there is no alteration the site topography.
b. Resource Conservation and Environmental Friendly Building Materials
To reduce the ecological footprint of the development, use of recycled material for construction
and conserving natural resources is of primary importance. In this light, the use of recyclable
building materials has been proposed for various building materials. It is also proposed to reuse
building components, minimization of construction wastes etc.
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur, Chapter V
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 104
The project is also committed towards conservation of water. This includes use of treated
sullage, rainwater harvesting, provision of low water flow fixtures and raising awareness on
means of water conservation.
c. Efficient use of Water and Water Recycling
The need for water conservation in the face of impending water crisis cannot be overemphasized.
The project will follow a three pronged management for water resource viz water resource
development, minimize use of water and recycle sullage generated within the site.
Rainwater harvesting across the entire project area is proposed to recharge groundwater. A
detailed storm water drainage system and water harvesting procedures are proposed to achieve
this.
The water demand is proposed to be brought down by the use of water efficient fixtures,
implement best management practices for water in both the Residential Group Housing Colony
and horticultural activities. An important means for achieving this is spreading awareness to the
occupants for generating water conservation awareness.
To reduce the freshwater demand of the project, sullage from site will be treated in a STP and
recycled for landscaping and flushing.
d. Use of Energy Efficient design and Eco-Friendly Equipment
The project will be designed such that there is optimal solar energy utilization, especially for
natural light availability. Shading will be provided on sides that will otherwise reduce the energy
efficiency of the building. Energy conservation will be one of the focuses during the planning,
development, construction and post construction stages.
e. Use of Renewable Energy
The electrical supply is largely dependent on thermal power plants that are largely responsible
for accelerating the phenomenon of global warming and consumption of limited natural
resources. It is of paramount importance to shift focus on other renewable sources of energy to
achieve sustainable development in the energy sector. The project area in Gurgaon receives
adequate hours and intensity of sunlight for effective solar energy generation. Taking full
cognizance of the availability of natural sunlight and technology, the project proposes the use of
solar energy to reduce the power demand of the project.
Solar energy will be used for the purpose of heating of the water.
f. Indoor Air Quality for Human Safety and Comfort
To provide the occupants with a safe building is the primary responsibility of a developer. Indoor
pollution sources that release gases or particles into the air are the primary cause of indoor air
Group Housing Colony EIA/EMP Report
Village Nangli Umarpur, Chapter V
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 105
quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not
bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying
indoor air pollutants out of the home. High temperature and humidity levels can also increase
concentrations of some pollutants. Likewise, it is proposed to use all user safe building materials
such as:
i. The buildings will be painted with low VOC, ammonia free paints.
ii. Asbestos will not be used.
iii. Adequate ventilation will be provided in each residential unit and floor.
iv. Adequate openings for sunlight to enter the building, thereby reducing chances of
microbial growth.
v. All building maintenance and cleaning materials will be kept in an isolated and well
ventilated room with restricted entry.
g. Effective Controls and Management Systems
It is proposed to establish a Management System that will comprise modern equipment’s as well
as an efficient team of maintenance staff.
i. Each tower as well as common area will be provided with fire alarm as well as water
sprinklers. All essential services such as lifts and water supply will be provided with
power back up.
ii. A security system for the entire group housing will be provided comprising intercom
facility, closed circuit camera to the entrance and round-the-clock manning.
iii. Separate entries and exits of residents from the guests are proposed. The staffs’ vehicles
will be provided with identification stickers while visitors’ vehicles will be monitored
through security guards at the entrances.
The project further proposes extensive green areas as avenues, parks and roadside plantations.
The plants not only serve various direct environmental facilities, but also have indirect positive
environmental impacts such as reduction in overall energy use in buildings. The balcony garden
is a natural development of the balcony’s role as a link between interior and exterior
environments. Efforts will be made to cover walls with climbers, as feasible.
5.5 COMMUNITY ISSUES
Apart from the site occupants, all efforts will be made to ensure that the exiting neighborhood is
not adversely affected by the project.
While, the site will not act as a thorough fare for vehicles, there shall be no restriction to
movement of on-foot visitors and cyclists.

5.6 ENERGY CONSERVATION
To achieve conservation of energy, appropriate design of a building is of paramount importance.
Accordingly, it is proposed to incorporate the guidelines of Energy conservation Building Code,
2005 for the structures of the Group Housing Colony.
The concept of passive solar design emphasizes architectural design approaches that minimize
building energy consumption by integrating conventional energy-efficient devices, such as
mechanical and electrical pumps, fans, lighting fixtures, and other equipment, with passive
design elements, such as building siting, an efficient envelope, appropriate amounts of
fenestration, increased day lighting design, and thermal mass. The basic idea of passive solar
design is to allow daylight, heat, and airflow into a building only when beneficial.
The project layout has been finalized after careful siting consideration of various group housing
colony components to optimize availability of natural sunlight. Advanced Solar Passive
Techniques are employed to achieve energy efficiency.
Glazed windows are located to receive maximum sunlight in winter. To reduce
heat losses during the night these windows are often double-glazed and have
insulating curtains.
Thermal storage wall is placed between the glazing and habitable space to prevent
solar radiation from directly entering the living space.
Passive cooling systems i.e. cooling directly from evaporation, convection
radiation without using any intermediate electrical devices.
Provisions for use of desert cooler (Indirect evaporative cooling which comprises
water, evaporative pads, a fan and a pump).
Effective measures have been incorporated to minimize the energy consumption in following
manners:
• Use of CFL lamps instead of GLS lamps for Flats.
• Use of CFL lamps instead of GLS lamps for Common area.
• T5 lamps are used instead of Normal Flourescent lamps in Basements
• Using electronic ballast for Discharge Lamps.
• Solar water heating systems shall be provided as per HAREDA norms.
5.7 TRANSPORTATION
A well planned road network is proposed within the project premises. Adequate parking will be
provided during construction phase to ensure that all heavy vehicles visiting the site are provided
parking space within the site. There shall be no parking on the access roads. The movement of
the vehicles will also be scheduled such that the peak hours are avoided.
In the operation phase, entry and exits will be from separate gates to minimize disturbance to the
approach roads to the project site. To avoid congestion of the approach roads, space will be

provided for vehicles waiting checking. Adequate parking is also proposed to ensure there is no
parking along the roads. Within the site, adequate wide roads are proposed. To achieve the same,
speed humps will be provided.

7.2.2 Emergency Response Plan (ERP)
The overall objective of an Emergency Response Plan (ERP) is to make use of the combined
resources at the site and outside services to achieve the following:
1. To localize the emergency and if possible eliminate it;
2. To minimize the effects of the accident on people and property;
3. Effect the rescue and medical treatment of casualties;
4. Safeguard other people;
5. Evacuate people to safe areas;
6. Informing and collaborating with statutory authorities;
7. Initially contain and ultimately bring the incident under control;
8. Preserve relevant records and equipment for the subsequent enquiry into the cause
and circumstances of the emergency;
9. Investigating and taking steps to prevent reoccurrence
The ERP is therefore related to identification of sources from which hazards can arise and
the maximum credible loss scenario that can take place in the concerned area. The plan
takes into account the maximum credible loss scenario - actions that can successfully

Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd. Page 117
mitigate the effects of losses/ emergency need to be well planned so that they would require
less effort and resources to control and terminate emergencies, should the same occur.
Main hazards identified for the project include hazards pertaining to fires in buildings and fire in
diesel storage areas, earthquake and LPG leakage and an ERP pertaining to these is described in
the following section.
7.3 RESPONSE IN CASE OF EARTHQUAKE
7.3.1 Response Procedures for Occupants
If indoors:
1. Take cover under a piece of heavy furniture or against an inside wall and hold on.
2. Stay inside: The most dangerous thing to do during the shaking of an earthquake is to try to
leave the building because objects can fall on you.
If outdoors:
Move into the open, away from buildings, streetlights, and utility wires. Once in the open, stay
there until the shaking stops.
If in a moving vehicle:
Stop quickly and stay in the vehicle. Move to a clear area away from buildings, trees, overpasses,
or utility wires. Once the shaking has stopped, proceed with caution. Avoid bridges or ramps
that might have been damaged by the quake.
After the quake
1. After the quake be prepared for aftershocks.
2. Although smaller than the main shock, aftershocks cause additional damage and may bring
weakened structures down. Aftershocks can occur in the first hours, days, weeks, or even
months after the quake.
Help injured or trapped persons.
1. Give first aid where appropriate. Do not move seriously injured persons unless they are in
immediate danger of further injury. Call for help.

7. The response team should immediately move to the point of fire and take all necessary steps to
stop the fire. If the fire is not controllable and spreads then the manager in charge should inform
the district authorities and call for external help.
8. The Emergency Response Team will provide immediate relief to the injured residents at the
scene of incident. Any injured persons should be evacuated on priority to the dispensary or one
of the nearest hospitals based on their condition.
Instructions for occupants
1. Get out of buildings as quickly and as safely as possible.
2. Use the stairs to escape. When evacuating, stay low to the ground.
3. If possible, cover mouth with a cloth to avoid inhaling smoke and gases.
4. Close doors in each room after escaping to delay the spread of the fire.
5. If in a room with a closed door.
6. If smoke is pouring in around the bottom of the door or if it feels hot, keep the door
closed.
7. Open a window to escape or for fresh air while awaiting rescue.
8. If there is no smoke at the bottom or top and the door is not hot, then open the door
slowly.

10. Stay out of damaged buildings.
11. Check that all wiring and utilities are safe.
A state of the art fire fighting system is proposed for the project to prevent and control fire
outbreaks. The fire fighting system will consist of portable fire extinguishers, hose reel, wet riser,
yard hydrant, automatic sprinkler system, and manual fire alarm system. The group housing
buildings will also be provided with automatic fire detection and alarm system.
7.6 RESOURCE CONSERVATION
The project will lead to utilization of various natural resources. As an environmentally
responsible corporate, the developers endeavor to conserve these resources by judicious
management and recycling and strive to build up these resources where possible.
Water Resources: The project will use treated water from nearby STP during construction
phase and HUDA supply during operation phase of the project. Given the national water
scenario, where availability if fresh water is fast dwindling, judicious use of the same cannot be
over emphasized. Following means are proposed to be adopted for conservation of this life
sustaining resource:
Limited withdrawal of groundwater: There will be no use of groundwater both during
construction and operational phase of the project. The construction phase will make use of
recycled water from STP of HUDA while water demand for operational phase will be met by
HUDA water supply.
Reduced use of water: To further minimize the use of available freshwater, various low flow
fixtures may be provided such as Low flow flushing systems, sensor based fixtures, waterless
urinals, tap aerators. Awareness will also be spread amongst the residents on the following lines:
Timely detection and repair of all leakages;
Turning off tap while brushing teeth;

trees. Once fully grown, they need not to be watered frequently.
Avoiding over watering of lawns. Good rains eliminate the need for watering for
more than a week.
Setting sprinklers to water the lawn or garden only, not the street or sidewalk;
Avoiding installation or use of ornamental water features unless they recycle the
water and avoiding running them during drought or hot weather;
Installation of high-pressure, low-volume nozzles on spray washers;
Replacement of high-volume hoses with high-pressure, low-volume cleaning
systems;
Equipping spring loaded shutoff nozzles on hoses;
Installation of float-controlled valve on the make-up line, closing filling line
during operation, provision of surge tanks for each system avoid overflow;
Washing vehicles less often, or using commercial car wash that recycles water;
Treatment and Recycling: The sullage generated from the sites will be treated in an on-
site Sewage Treatment Plant of 240 KLD & 135 KLD capacity each. This will enable the
treated sullage to be used for flushing and landscaping thereby reducing the requirement of
freshwater for these purposes.
Rainwater harvesting: The increased hard surface of group housing increases the runoff
as compared to the otherwise barren land. It is proposed to harvest this rainwater runoff
that will recharge the groundwater resource while reducing the burden of storm water

management of the city and eventually natural water bodies. Apart from the open spaces, it
is proposed to harvest the roof top rainwater. The storm water will be treated through an oil
and grease trap and allowed to flow through layers of sand and gravel for filtration prior to
reaching the water table, to avoid any possibility of groundwater contamination.
Construction materials: As a large construction, the project will require various kinds of
natural construction materials such as sand, gravel etc. It is proposed for prior estimation of
required quantities of these materials and procurement only as per requirement. This will
also result in cost-efficiency. Excavated soil from the project site will be used within the
site to the extent feasible. Excess soil will be made available to the construction sites, as
per need.
Energy: To conserve the energy resources, good practices will be followed during the
construction phase such as turning off lights and equipments when not in use, ensuring fuel
efficiency of motors and vehicles through proper maintenance and minimal work at night.
The principles of energy conservation will also be embedded in the buildings through use
of energy efficient fixtures, maximum availability of natural light and use of solar energy
for street lighting.
7.7 RESETTLEMENT AND REHABILITATION
The project will not result in displacement of any local population and hence, does not
require a resettlement and rehabilitation study.

CHAPTER-9
ENVIRONMENTAL MANAGEMENT PLAN
9.1 INTRODUCTION
Identification and prediction of impacts further needs to suggest the mitigative measures which
would play a vital role in prevention of environmental degradation during construction and
operational phase of the Group HousingColony. This leads to preparation of Environmental
Management Plan (EMP), therefore EMP forms an imperative part of EIA process.
The Environmental Management plan is a site specific plan developed to ensure that the project
is implemented in an environmentally sustainable manner where all contractors and
subcontractors, including consultants if any, understand the potential environmental risks arising
from the project and take appropriate actions to minimize those risks. EMP also ensures that the
project implementation is carried out in accordance with the planned design and by taking
appropriate mitigates actions to reduce adverse environmental impacts during project’s life cycle.
The project will create certain inevitable impacts, mainly during construction phase, although
within permissible limits as mentioned in Chapter 4 and can be reduced significantly with the
help of effective implementation of a well-designed EMP. The potential environmental impacts,
which need to be regulated, are mentioned below:
Air pollution due to the emission of particulate matter and gaseous pollutants from
operation of D.G.Sets during power failure and vehicular movement;
Noise pollution due to various noise generating equipment as well as vehicular
movement;
Water resource management to ensure continuous water supply.
Sullage generation from sanitary/domestic activities; and
Generation of municipal solid wastes from residences, maintenance of roads, parks,
common areas including constructional, electrical and plumbing wastes.
Energy conservation methods.
Maintenance of Building Management Systems and emergency aids.
To ensure better environment in & around the project site, effective EMP is developed separately
for construction and operational phase.
9.2 ENVIRONMENTAL MANAGEMENT STRATEGIES
Strategy for environmental management in construction work should be based on three-pronged
approach comprising of:
Pollution prevention.
Pollution control.
Protection of pollution recipients.

9.2.1 Topography and Physiography
During the development, construction and post construction phase of the Group Housing Colony,
no significant impact is anticipated on local or regional topography and Physiography, hence
exhaustive management plan is not required. It is however proposed to carry out extensive
turfing with local species apart from proposed plantations and greens.
9.2.2 Soil
9.2.2.1 Development & Construction Phase
During the construction phase, various kinds of wastes are generated that will be disposed in
varied ways. The following measures will be taken to prevent soil contamination at site and
ensure waste management:
Vegetation and top soil management:
Remove vegetative cover only from the specific site on which construction will take
place.
Plantation as proposed shall be started at the earliest.
The top soil will be stripped from constructional areas and stockpiled for later reuse in
landscaping.
Promote use of organic fertilizers.
Construction of erosion prevention troughs, as deemed necessary.
To prevent the erosion of excavated loose soil produced as a result of excavation, site
preparation activities and excavation work would be undertaken during dry season after
monsoon is over.
Construction Debris:
Fuel and oil would be stored in cement lined storage yard and handled carefully to
prevent soil contamination through leakage or spillage.
All metal, paper, plastic wastes, debris and cuttings would be collected from site as soon
as particular construction activity is over.
During construction of flexible pavement, bitumen wastes will be collected (if any) and
disposed in environmentally sound manner.
The number, frequency and area of movement of heavy machinery will also be restricted.
Recycling of construction wastes into aggregates for use in the project site.
Used oil from DG Sets should be stored in HDPE drums in isolated covered facility and
disposed off as per the Hazardous Wastes (Management &Handling) Rules, 1989.
Wastes from the labor camps will be collected and disposed as per the existing practices
in the site.

VillageNangliUmarpur, Chapter IX
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 127
9.2.2.2 Post Construction Phase
To prevent soil contamination at site, the most important aspect is to manage the solid wastes
that will be generated during the operation phase. The Environmental Management Plan for the
solid waste focuses on three major components during the life cycle of the waste management
system i.e. collection, transportation, and treatment or disposal.
Collection and segregation of wastes
Solid waste generated from project would be collected door to door and segregated into
decomposable, recyclable and inert wastes.
Decomposable wastes will be decomposed and converted to manure to be used for
horticulture.
Recyclable waste would be sold to vendors.
Inert waste which comprises a very small amount of the total solid waste generated
would be temporarily stored within the project premises.
Waste bins would be placed at the strategic locations such as inter section of internal
roads, parks, common places, etc.
To minimize littering and odors, waste will be stored in well-designed containers/ bins
that will be located at strategic locations to minimize disturbance in traffic flow.
Care would be taken such that the collection vehicles are well maintained and generate
minimum noise and emissions. During transportation of the waste, it will be covered to
avoid littering.
Transportation:
Only the non-recyclable and non-biodegradable waste will be transported to the Govt. approved
agency. The segregation, transportation and disposal of wastes will be done by the authorized
agency that will take care of the waste management of the project during the operational phase of
the project.

Figure 9.1: Waste Management Flow Diagram
Disposal
With regards to the disposal/ treatment of waste, the management will take the services of the
authorized agency for waste management and disposal of the same on the project site during its
operational phase.
9.2.3 Hydrology
9.2.3.1 Ground water Hydrology
Development & Construction Phase
The water requirement during the construction period will be met by recycled water from STP.
The following are also proposed to further reduce the demand of freshwater:
Curing water will be sprayed on concrete structures and free flow of water not allowed.
After liberal curing on the first day, all concrete structures will be painted with curing
chemical to save water to stop daily water curing hence save water.
Concrete structures will be covered with thick cloth/gunny bags and then water sprayed
on them to avoid water rebound and ensure sustained and complete curing.
Pools will be made using cement and sand mortar to avoid water flowing away from the
flat surface while curing.
Group Housing Colony EIA/EMP Report
VillageNangliUmarpur, Chapter IX
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 129
Water ponding will be done on all sunken slabs. This will also highlight the importance
of having an impervious formwork.
Post Construction Phase
It is proposed to conserve groundwater resources through the combined means of water resource
development, minimized water consumption and reuse of treated sullage to reduce freshwater
demand.
9.2.3.2 Water Resource Development
Keeping in view the rainfall, storm water drainage system will be developed to carry the runoff.
The storm water disposal system for the premises shall be self-sufficient to avoid any
collection/stagnation and flooding of water. The amount of storm water run-off depends upon
many factors such as intensity and duration of precipitation, characteristics of the tributary area
and the time required for such flow to reach the drains. The drains shall be located near the
carriage way along either side of the roads. Taking the advantage of road camber, the rainfall run
off from roads shall flow towards the drains. Storm water from various buildingsbe connected to
adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 14
rainwater harvesting pits at selected locations, which will catch the maximum run-off from the
area.
1) Since the existing topography is congenial to surface disposal, a network of storm water
pipe drains is planned adjacent to roads. All building roof water will be brought down
through rain water pipes.
2) Storm water system consists of pipe drain, catch basins and seepage pits at regular
intervals for rain water harvesting and ground water recharging.
Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak
hourly rainfall has been considered as 45 mm/hr. The recharge pit of adequate diameter and
depth is constructed for recharging the water. Inside the recharge pit, a recharge bore is
constructed having adequate diameter and depth. The ground water level in the area is 30-40
meters bgl. The bottom of the recharge structure will be kept 5 m above this level. At the bottom
of the recharge well, a filter media is provided to avoid choking of the recharge bore. Design
specifications of the rain water harvesting plan are as follows:
Catchments/roofs would be accessible for regular cleaning.
The roof will have smooth, hard and dense surface which is less likely to be damaged
allowing release of material into the water. Roof painting has been avoided since most
paints contain toxic substances and may peel off.
All gutter ends will be fitted with a wire mesh screen and a first flush device would be
installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags
Group Housing Colony EIA/EMP Report
VillageNangliUmarpur, Chapter IX
Sector-62, Gurgaon, Haryana

and paper pieces will get arrested by the mesh at the terrace outlet and to prevent
contamination by ensuring that the runoff from the first 10-20 minutes of rainfall is
flushed off.
No sewage or sullage would be admitted into the system.
No sullage from areas likely to have oil, grease, or other pollutants has been connected to
the system.
Calculations for storm water load
Plot Area of Phase-I = 25,454.73 m2
Roof-top area = Ground Coverage of Pocket-A = 8,810 m2
Green Area = 10,708.66 m2
Green Area (without water body) = 7,870.8m2
Paved Area = Plot Area – (Roof-top Area + Green area)
= 25,454.73 – (8,810 +10,708.66)
= 5,936.07m2

= 186.986 m3/hr
Total Runoff Load = 317.16+ 70.84 + 186.986 m3/hr
= 574.986m3/hr

Taking the effective length, width and depth of a Recharge pit 3 m, 3 m and 2.25 m respectively,
Volume of a single Recharge pit = l x b x h = 3 × 3 × 2.25 = 20.25 m3
Hence No. of pits required = 143.747 / 20.25 = 7.1 pits say 7 pits

Paved Area = 4,770.12× 0.045 × 0.70
= 150.259 m3/hr
Total Runoff Load = 336.528 + 56.87 +150.259 m3/hr
= 543.657m3/hr
Taking 15 minutes Retention Time, Total volume of storm water = 543.657/ 4
= 135.914 m3
Taking the effective length, width and depth of a Recharge pit 3 m, 3 m and 2.25 m respectively,
Volume of a single Recharge pit = l x b x h = 3 × 3 × 2.25 = 20.25 m3
Hence No. of pits required = 135.914 / 20.25 = 6.7 Pits say 7 pits

As 1 pit/acre is required so, total 14 rain water harvesting pits will be required for 14.025 acre
land.
Total of 14 Rain Water Harvesting pitsare being proposed for artificial rain water recharge
within the project premises.
Figure 9.2: Typical Rain Water Harvesting Pit Design
The rainwater from the terraces and related clean paved areas and the green areas of individual
areas shall be collected in the collection chambers and shall be ultimately connected to the main
storm-water drainage system. The run-off collected from the terraces/ roof area and the green
areas will be diverted to the “Rain Water Harvesting pits” for underground aquifer charging.
Proper “De-silting Chamber” filtration Media and Bye-Pass arrangement shall be prior to
harvesting. Overflow from these wells shall continue into the main drainage system. In the event
of an excessive rain, the discharge will be disposed off outside the site as per local conditions.
Run-off from other paved/ road/ green areas shall be diverted into the underground aquifer
through collection wells and trenches for rainwater harvesting. It is proposed to provide
pretreatment i.e. Grease/ Oil separator etc. as may be the requirement.
Group Housing Colony EIA/EMP Report
VillageNangliUmarpur, Chapter IX
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd 133
Storm water management system
Since the storm water on site will be harvested for ground water recharge, proper management of
this resource is necessary to prevent contamination. Hence, regular inspection and cleaning of
storm drains shall be carried out. Use of fertilizers and pesticides will be avoided prior to and
during monsoons. Clarifiers or oil/ water separators shall also be installed in all the parking
areas.
Minimal Water Consumption
To reduce the water consumption, awareness along the following lines will be spread amongst
the management and maintenance team:
Installation of water meters conforming to ISO standards at inlet and outlet point of
water supply.
To further lower the water consumption, options of Low flow flushing systems,
sensor based fixtures, and tap aerators etc. will be explored.
Leak detection
Drip irrigation for shrubs and trees
Use of low-volume, low-angle sprinklers for lawn areas
The message of water conservation will be spread amongst the residents through awareness
campaigns and pamphlets. Following tips shall be provided to the residents for conserving water.
Timely detection and repair of all leakages;
Turning off tap while brushing teeth;
Use of mug rather than running water for shaving;
Avoiding/minimizing use of shower/bath tub in bathroom;
Turning off faucets while soaping and rinsing clothes;
Using automatic washing machine only when it is fully loaded;
Avoiding use of running water while hand-washing;
Avoiding use of running water for releasing ice tray ahead of time from freezer;
Turning off the main valve of water while going outdoor;
Avoiding use of hose for washing floors; Use of broom may be preferred;
Watering of lawn or garden during the coolest part of the day (early morning or late
evening, hours) when temperature and wind speed are lowest. This reduces losses
due to evaporation.
Planting of native and/or drought tolerant grasses, ground covers, shrubs and trees.
Once fully grown, they need not to be watered frequently.
Avoiding over watering of lawns. Good rains eliminate the need for watering for
more than a week.
Setting sprinklers to water the lawn or garden only, not the street or sidewalk;

Avoiding installation or use of ornamental water features unless they recycle the
water and avoiding running them during drought or hot weather;
Installation of high-pressure, low-volume nozzles on spray washers;
Replacement of high-volume hoses with high-pressure, low-volume cleaning
systems;
Equipping spring loaded shutoff nozzles on hoses;
Installation of float-controlled valve on the make-up line, closing filling line during
operation, provision of surge tanks for each system avoid overflow;
Washing vehicles less often, or using commercial car wash that recycles water.
Re-use of treated sullage
It is expected that the project will generate approx. 200 KLD in Phase-I & 114 KLD in Phase-II
of total sullage. The sullage will be treated in the 2 STPs of 240 & 135 KLD capacity within the
complex and the treated wastewater will be used for flushing, horticultureand rest will be
discharged to nearby land for construction purposes.
9.2.3.3 Ground water Quality
Development and Construction Phase
To ensure against any groundwater pollution through leaching of soil, solid waste management
plan ensuring timely collection of wastes will be followed. The collected wastes will be stored at
designated area and disposed as per the standard procedures in line with the statutory
requirements.
Post Construction Phase
The ground water pollution can arise from improper waste handling or by recharge of
groundwater through contaminated storm water. A well planned solid waste management as
discussed in chapter 2 is proposed for the operation phase that will ensure against any chances of
soil or groundwater pollution on this account.
Storm water collects dirt and garbage along its flow. Contamination of this water with spilled oil/
grease is especially of concern when recharging is proposed. Hence, preliminary treatment for oil
and grease and filtration through layers of sand and gravel is proposed prior to recharge of the
groundwater.
Landscaping water enters the soil and finally the groundwater. It is thus of utmost importance
that only clean water is used for horticulture purposes. The water from the households will
contain significant amounts of detergent and soap that is undesirable for plants, soil and in
groundwater. Hence, it is proposed to treat sullage from the sites up to tertiary level, and be used
for landscaping only thereafter. Regular monitoring of treated sullage shall be carried out to
ensure that all parameters are within acceptable levels.

Traffic pollution management: Internal roads would be maintained in good conditions to
control the dust emissions. Awareness will be raised amongst the residents for use of low sulphur
fuel.
Plantation development: Vegetation is an effective means for controlling air pollution due its
dual action of acting as a barrier between the source of emission and receptors and also as a sink
for various pollutants. It is proposed to develop plantation of species effective in absorption of
expected pollutants at site, along the internal roads and on the periphery of the Group Housing
Colony. Suggested species for plantation are:
Cassia Fistula(Amaltas)
Bauhinia purpurea(Kachnar)
Saracaasoca(Sitaashok)
Jacaranda mimosifolia (Neeligulmohar)
Astoniascholaris (Scholar tree)
Roystoniaregia (Royal palm)
9.2.5 Noise Levels
9.2.5.1 Development and Construction Phase
During the construction phase, some noise will be generated through the operation of
construction machines, excavators, DG sets, etc. Following measures would be taken; into
consideration to mitigate the noise at construction site:
Use of well-maintained equipment fitted with silencers and providing noise
shields near the heavy construction operations
Acoustic enclosures would be provide to DG sets at the construction site,
Earmuff and other protection devices shall be provided to laborers working in
high noise generating machines.
High noise activities shall be carried out during daytime.
9.2.6 Post Construction Phase
The main sources of noise during this phase are the intermittent use of DG Sets and traffic. The
principles of noise emission control and screening are proposed for the two different scenarios of
noise generation.
9.2.6.1 Noise emission control
All the D.G. Sets will be provided with acoustic enclosures ensuring 25 dB (A) insertion loss or
for meeting the ambient noise standards whichever is higher as per CPCB norms. It will be
ensured that the manufacturer provides acoustic enclosures as an integral part with Diesel
Generator Sets.

9.2.7.1 Development and construction phase
During the development, construction and post construction phase, no tree will be cut and
therefore no impact is anticipated on terrestrial ecology. Site clearing shall be carried out strictly
as per plan. Workers shall be advised against cutting, uprooting, coppicing of trees or small trees
present in and around the project site for cooking. Workers shall also be discouraged from
wandering in nearby areas with plantation or dense vegetation.
Further, green belt will be developed on the periphery and along the internal roads of project site
during the construction phase itself that will act as a curtain to restrict the movement of
pollutants from either side of the project and improve site aesthetics.
9.2.7.2 Post construction phase
During the post construction phase, green belt will be developed and maintained. Ornamental
plant species and grasses will be planted in open space within the premises. 30% area of total
area is proposed to be maintained green in the project site. Proposed list of species for plantation

Group Housing Colony EIA/EMP Report
Village NangliUmarpur,Chapter X
Sector-62, Gurgaon, Haryana
M/s EMAAR MGF Land Ltd. Page 152
10.4.1 Land Environment
The land use pattern of the study area is mainly residential, agricultural and open & degraded
vegetation. The site falls under residential land use as per Gurgaon-Manesar Urban Complex,
2021. When awarded to the project proponent, the land was a barren stretch.
The project will be developed as per the provisions of the Gurgaon-Manesar Urban Complex
2021. The construction phase of any construction project poses the threat of soil contamination
and soil erosion, mainly during the construction phase. Inadequate solid waste management may
also cause soil contamination during operation phase. The estimated waste generation during
operation phase is 1,370.955 kg/day.
During construction phase, excavation related work will be avoided during the monsoons and
site clearing will be carried out for specific areas being developed. All wastes from site will be
regularly removed and disposed/ sold. An efficient solid waste management is proposed
comprising door-to-door waste collection, segregation of solid waste management facility within
the site, and their disposal. Solid waste will be disposed by sale of recyclable wastes to vendors.
10.4.2 Water environment
The project site is located at Village-NangliUmarpur, Sector-62, Gurgaon.The water requirement
during construction phase will be met by treated water from nearby STP (HUDA). A
combination of efficient water management to reduce water consumption, reuse of treated
wastewater to reduce freshwater demand and rainwater harvesting to replenish groundwater is
proposed to have a positive bearing on the water environment of the region.
Sewage Treatment Plants (STP’s) of capacity 240 & 135 KLDwill be set up to treatwaste water.
10.4.3 Air Environment
During construction phase, the major air pollutant of prime concern is PM2.5,PM10as impacts of
other emissions such as SO2, NO2, and CO will not be significant because the nature of sources
is such that the emissions are distributed spatially as well as temporal. Monitored average
PM2.5,PM10 level exceeded NAAQS at all the five locations. The levels of PM 2.5,PM10,NO2, SO2
and CO at all the five locations were within the standards prescribed by NAAQS at all the five
locations. Thus dust emissions from construction activities shall require comprehensive
mitigation measures and best construction practices.
Adequate stack heights will be proposed for D.G. Sets of2780 KVAcapacity (2 X 500 KVA + 2
X 320 KVA+3X 380 KVA)above the ground to provide for sufficient dispersion of pollutants.
Water sprinklers will be used to suppress dust during construction. During the operation phase,
green belt and green area development is proposed to restrict and absorb air pollutants.

10.4.4 Noise Environment
Noise levels were observed at four locations within the study area. Levels of background noise
monitored in exceed the limits at 55 dB (A) and 45dB (A) for daytime and night time
respectively.
The noise emitted from heavy-duty construction equipments during construction period being
high shall require occupational preventive measures and temporary noise barriers for noise
attenuation. The construction period being about four to five year duration, will require
significant mitigation measures such as restricted loud noise activities to daytime, provision of
PPEs and acoustic enclosures for D.G. Sets.
In the operation phase, noise pollution will be checked through acoustic enclosures of DG Sets
and green belt plantation.
10.4.5 Biological environment
There is also no tree cutting involved in the project. Additionally, there will be avenue
plantations, green walls and roof tops. The landscaping will include native species that will
attract local birds and insects, reduce pollution and improve aesthetics and micro-climate of the
region. Total green area measures 17,027.16m2i.e30% of plot area which will be area under tree
plantation at periphery and along the roads. Evergreen tall and ornamental trees like Acacia
auriculiformis, Acacia delbata, Aeglemarmelos, Adina cordifolia and ornamental shrubs like
Bambusaarundinacia, Bambusa vulgaris have been proposed to be planted inside the premises.
Parks will also be developed by the project proponent.
List of the plants is given below in Table 10.2.
