SEWAGE TREATMENT TECHNOLOGY

FAB TECHNOLOGY

Sewerage System

An external sewage network shall collect the sewage from all units, and flow by gravity to the

sewage treatment plant.

Following are the benefits of providing the Sewage Treatment Plant:

Reduced net daily water requirement.

Reduced dependence on the public utilities for water supply and sewerage system.

Sludge generated from the Sewage Treatment Plant shall be rich in organic content and

an excellent fertilizer for horticultural purposes.

(c) B.O.D. : <10 mg/l

(d) C.O.D. : <30 mg/l

(e) Total Suspended Solids : <10 mg/l



c. Treatment Technology

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

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

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

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

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

tank.

The attached growth fluidized aerobic bed reactor (FAB) process combines the biological

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

aeration for treatment of the wastewater.

The wastewater after screening is collected in an equalization tank. The equalization tank is

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

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

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

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

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

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

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

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

agitation ensures good water to micro-organism contact.

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

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

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

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

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

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



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

wastewater provides oxygen for the aerobic reactions at the bio-film surface. Waste products

from the metabolic processes diffuse outward & get carried away by the wastewater or air

currents through the voids of the media.

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

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

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

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

the inclined surface and the residence time within the media.

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

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

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

fluid approaches zero. Boundary layers are necessary in functioning tube settlers, to allow

suspended solids to separate from the viscous carrier fluid. Under gravitational forces, they

will settle to the hydraulic surface of the tube and subsequently from the clarifier media.

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

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

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

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

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

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

At the bottom of the Tube deck, where the sludge leaves the Tube surface, the larger

agglomerated captures smaller particles in the upcoming stream. This solid contact

phenomenon greatly enhances the capture efficiency.

Stages of Treatment: The treatment process consists of the following stages:

Equalization



Bio- Degradation

Clarification & Settling

Filtration

Figure 2.3: Schematic Diagram of STP

Sewer System

The alignment and slope of the sewer line will follow the road network, drains or natural

ground surface and will be connected to the trunk sewers. The discharge point will be a

treatment plant, a pumping station, a water course or an intercepting sewer. Pumping stations

would be provided at places where the natural slope of the terrain is insufficient to permit

gravity flow or the cost of excavation is uneconomical to do the same.



2.9 RAIN WATER HARVESTING

The storm water collection system for the premises will 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 will be connected to adjacent

drain by a pipe through catch basins. Therefore, it has been calculated to provide rainwater

harvesting pits at selected locations, which will catch the entire run-off from site.

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 shaft is having adequate diameter

including weep hole, vent pipe and depth. Inside the shaft, a recharge pit of 4 m diameter and

6 m depth is constructed for recharging the available water to the deeper aquifer.

At the bottom of the shaft a filter media is provided to avoid choking of the recharge well.

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 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.

Storm water load (for Commercial area, Common facilities and Group Housing)

Ground Coverage = 22,015 m2

Green Area = 1, 95,464.37 m2

Paved Area = Site Area – (Ground Coverage + Green Area)

= 6,39,808 – (22,015 + 1,95,464.37)

= 4, 22,328.63m2

Run-off calculation:


= 22,015 x 0.045 x 0.80 = 792.54 m3/hr

Green Area = 1,95,464.37 m2

= 1, 95,464.37 x 0.045 x 0.1 = 879.589,m3/hr

Paved Area = 4,22,329 m2

= 4,22,328.63 x 0.045 x 0.75 = 14,253.59 m3/hr

Total Runoff Load = (792.54 + 879.589 + 14,253.59) m3/hr

= 15925.719m3/hr

Taking 20 minutes retention time, total volume of storm water will become = 15925.719/3

= 5308.573 m3

Taking the effective diameter and depth of a RWH pit as 4 m and 6 m respectively, volume of

RWH Pit will be =πr2h = 3.14 x 2 x 2 x 6 = 75.36 m3

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 environment was conducted from October-December, 2016. 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 area measures 6, 69,876.14m2 (165.53 acre) which is earmarked for development of Residential development as per Gurgaon-Manesar Urban Complex, 2021. The probability of impacts from the expansion of Residential Plotted Colony cum Group Housing project is anticipated 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 IX (d) 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-XXIV. 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. 3.4.1 Meteorology



A meteorological station was set up at the project premises. Meteorological data was generated during the post monsoon season, October -December, 2016. The following parameters were recorded at hourly intervals continuously during monitoring period: - Wind speed - Wind direction - Air temperature

Table-3.1 gives summarized meteorological data for the worst day. Figure-3.1 gives the wind-rose diagram for the monitoring period.

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 map showing the air quality monitoring stations is enclosed as Annexure-VI.

Table 3.2: Location of Ambient Air Quality Monitoring Stations

Locations Locations Code Direction Distance (km) AAQ1 Project site Center Zero AAQ2 Udaka E 1.9 km AAQ3 Ata SE 0.6 km AAQ4 Pipaka W 3 km AAQ5 Rampur Khera NE 0.85 km

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 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.

3.4.3 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 locations are given in Table-3.4 below. Table 3.4 Noise Level Monitoring Stations in the study area

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 October 2016- December 2016.

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 MoEFCC guidance. Hence quality of ground water was compared with IS: 10500: 1991 (Reaffirmed 1993 With Amendment NO -3 July 2010) for drinking purposes. 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. The sampling locations for ground water are given in Table-3.7

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. 3.4.5.1 Topography

The landform of the project site is a plain land with average elevation of about 99.25 m-95.5 m. The land environment is described by landuse / landcover of the study area within 10 km radius and soil environment of the study area within 5 km radius.

3.4.5.2 Land Use Description

The land use / land cover of the project site was done to identify the land use pattern and land cover pattern of the study area. The study of land use in the area enables one to know about the land that can be used for various development activities envisaged in post project scenario. It also enables to envisage the scenario emerging due to the increase in demand for land with increase in population and the impacts arising due to the interface with the various project activities.

Objectives of the Study The objectives of the present study are: To map the study area with respect to various land use/land cover change over the past 10 years.

To identify the sensitive areas within 10 km radius around the project site.

Methodology



The land use / land cover pattern has been established based on the analysis of the data received from satellite imagery by making land use/land cover map with the help of GIS technique. References have been taken from Survey of India. Also the data based on Census of India, 2001 was referred and landuse study was done within 10 km radius area with limited ground truth verifications. Ground and ancillary information have been used to identify the sensitive places within 10 km radius of the project.

Land Use Pattern Classification and description

The classification of landuse / landcover pattern of the study area is mainly dominated by the types - agricultural land, waterbodies, canals, settlements or cultural use, and etc. The agricultural land covers the majority of the land which is about 80.9% of the study area. The land use data are presented in Table 3.9 and also highlighted with a pie chart at Figure 3.3. The landuse /land cover map is presented in Annexure-V (e).

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 3. Pugmark method – 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.



Aquatic life

The Phytoplankton in the lakes is basically dominated by filamentous forms. The dominant ones are Chaetophora sp., Cladophora sp., Spirogyra sp. The Zooplanktons are basically dominated by Crustaceans and Rotifers.

3.5 SOCIO ECONOMIC IMPACT ASSESSMENT

3.5.1 INTRODUCTION

Socio-Economic Impact Assessment (SEIA) refers to the systematic analysis of various social and

economic characteristics of the human beings living in the geographical / study area around the

proposed project location. SEIA is carried out separately but concurrently with Environment Impact

Assessment (EIA) study. The SEIA focuses on the likely effects of the project on social and economic

well-being of the community. The impact(s) may be direct or indirect, positive or negative. In this

section of the EIA Report an attempt has been made to assess the composite Socio-Economic Impact of

the project – Expansion of Residential Plotted Colony (Including Group Housing “Raheja Aranya”

Project at Village Sohna and Raipur, Sector 11 & 14, Dist. Gurgaon, Haryana.

3.5.2 OBJECTIVES OF SEIA

The prime objective of the current study is to assess the likely impact of the project on socio-economic

characteristics of people living in the study area. Further, it is to be gauged whether the impact would be

direct or indirect and whether the said impact would be positive or negative. Lastly, it is to be

comprehended if the impact is negative and how the same could be mitigated.

3.5.3 SCOPE

The Scope of the study is as follows:

a) Collection of baseline data of the study area.

b) Collation of data, analyses and generation of tables.

c) Comprehension of socio-economic status of the people living in the study area.



d) Identification and inventory of probable impacts of the project on social and economic aspects in the

study area.

e) Assessment of the probable impacts of the project on the people living in the study area.

f) Facilitation of sustainability of positive impact by recommending community development

initiatives in the study area.

g) Suggestion of mitigation measures in case of adverse impact.

3.5.4 METHODOLOGY

For composite Socio-Economic Impact Assessment of projects, 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 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 which spans a radius of

10 km from the periphery of the boundary of the project site. In each selected habitation, a specified

number of representative households were selected for collection of information through face to face

interviews with head of the household or any responsible member of the family.

Census and Sample Survey

To assess the likely impacts of the project, Census data (viz. Population Census Abstract and Amenities-

2011) of all the habitations identified were taken into consideration to prepare the data base. It is treated

as a census survey because all habitations located in the area were considered for the collection of

information. Sample Survey was conducted for substantiating of socio-economic data got through the

Census. Further, in selected habitation a household survey was conducted by drawing representative

sample of households. Since, collection of information from all the households in a habitation is time

consuming and expensive, the sample survey approach was adopted for collection of information

from the selection of villages and households in the village(s) / town(s).

Sample Design



Two-Stage Sampling Design was adopted in the study area. The First Stage Units were Census

village(s) / town(s) and the Ultimate Stage Units were households in the selected village(s) / town(s).

Method of selection of First Stage Units

Probability Proportional to size without replacement and vicinity to the project site was taken into

consideration while selecting the habitations from the list of Census village(s) / town(s).

Method of selection of Ultimate Stage Units

The ultimate stage sampling unit is households. The households for survey are selected by simple random

sampling technique.

Sample Size

While deciding the sample size the following factors were taken into account: Confidence Level (95%,

Table value: 1.96); Degree of precision (Δ): 0.5; Variation in population / Standard Deviation (σ); The

sample size at each level (village and household) was decided by using the formula n = √ {(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.

Survey Instruments

The following Schedules / Questionnaires were developed for collection of primary data from the

households and villages / towns:

Questionnaire / Schedule for Village / Town Particulars

Questionnaire / Schedule for Household Details and Project Perception

Each of these data instruments has segment blocks and there are both open-ended and closed-ended questions.

Steps in preparing the SEIA Report

study area. Accordingly, there may be some variation in the total population of the study area including

that of sex ratio, after the project is completed.

Employment Opportunities

Local labourers will be hired from nearby areas during construction phase. So, there will be no need to

create permanent facilities for long-term housing of operational workers. The direct and indirect

employment will be provided during the construction and operation phase of the project at both skilled

and unskilled levels to the local people on priority basis. Socio-economic standard of people will

improve due to increased employment opportunities provided by this project. Besides, the local people

will have both employment and business opportunities. The socio-economic standard of the local people

will be raised due to these enhanced employment and business opportunities.

This will lead to better quality of life, improvement in the living conditions and will also set a standard

for future developments in the area. It is a positive impact of the project.

Impact on Road Development

Movement of vehicles to and fro the project site is expected during the construction period. This

movement is expected to continue when the project becomes functional. Hence, there is scope for

further strengthening the road development in the area with adequate parking space to allow smooth

movement in and around the project area.

Impact on Law & Order

As workers to be employed in the proposed project is expected to increase both during the construction

and operation phases, law & order or administrative institution may be further upgraded or strengthen

close to the project site.

Impact on Health

In the operational phase, there are no chances of any major diseases due to the construction work.



However, to meet any emergency few safety measures are outlined below:

a) Safe Working Environment: The project proponent shall ensure health and safety of all the

employees at work. All efforts will be made to provide and maintain a safe work environment and

ensure that the machinery and equipment in use is safe for employees.

b) Provision of First Aid: In case of any accidents arising out of the proposed construction works,

timely and prompt first aid treatment is, often, the most important tool. Suitable first aid

arrangements shall be made at the site for rendering immediate first aid in case of any injury. The

first-aiders will be well trained in handling patients working in the project.

c) Regular Medical Examination: For all workers, medical examination will be made on regular

basis.

d) Health Education: Adequate health education & information related to the work will be provided to

the workers so that their health & safety can be ensured.

CHAPTER-4 ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION

MEASURES

4.1 INTRODUCTION This chapter discusses identification and appraisal of various environmental impacts due to expansion of project ‘Raheja Aranya’. 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. The project will be constructed and developed gradually in a time span of 2-3 years (approx.). For Plotted Colony development, basic infrastructure like internal road, sewerage system, storm water drainage, street lighting etc. will be provided. 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 expansion of the project 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.

4.5 ASSESSMENT OF ENVIRONMENTAL IMPACTS DURING DEVELOPMENT AND CONSTRUCTION PHASE

4.5.1 Topography Impact: Topography of the project site is fairly flat. Further, it is an expansion project thus topography and physiography of the area will not be affected during construction/development and operation phase of the project. Hence, no significant impact is anticipated on the topography and physiographic from project. It is further proposed to develop green area with plantation of local species to improve the environment of the region. Mitigation Measure: Since there is no significant impact on topography from the project, no mitigation measures are proposed. It is however proposed that apart from the proposed plantation greens, turfing with local species be carried out.

4.5.2 Land Use Pattern Impact: It is an expansion of a Residential Plotted Colony and the development is in accordance with Gurgaon-Manesar Urban Complex, 2021. Hence, no impact is expected on landuse as a result of the project.

4.5.3 Land Environment Impact: Soil would be excavated at project site for Group Housing part of the colony. 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 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/construction phase of Expansion of Residential Plotted Colony cum Group Housing Project ‘Raheja Aranya’. Debris and waste 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 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 requirement.

4.5.4.2 Ground Water Hydrology Ground Water Hydrology Impact: Water requirement during construction phase will vary depending upon construction activities and will be met from recycled water of 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 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. 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. 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.



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. 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/development of the project. No tree felling is involved, as the site is devoid of plantation except local herbs and shrubs. Birds and other domesticated biodiversity observed near the project site are common and already adapted to thrive in humanly colonized habitats. The project will not have any negative ecological impact. There is no forest involved in the project site and therefore there will be no effect on ecology of the area. Mitigation Measures: It is to proposed develop extensive green area within the project site to improve the aesthetics which will also help in reduction of air pollution, noise pollution and provide suitable habitat for local birds and faunal species.

4.5.8 Economic Impacts Impact: Long term, positive economic impacts are anticipated from the construction/development of the project which is likely to be experienced in a duration of 3-4 years. The project will give a short-lived stimulus to the local labour and traders during construction/development phase. Noticeable flow-on economic impacts will be experienced in 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 the project. During Opearytion phase,



the project will generate direct and indirect employment opportunities generating long term positive economic impacts

4.5.9 Socio-Economic During the development and construction phase, about 200 to 300 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 condition of the area.

4.5.10 Construction Camp Impact: During the development and construction phase, most of the laborers will be hired from local areas. Therefore, temporary labour hutments will be constructed to accommodate the laborers at project site. This may lead to sanitation issues. 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, mobile type toilet facilities, waste water and solid waste disposal system. Other safety precautions to be maintained at work site include provision of PPEs, guarding of dangerous machine parts, maintenance of equipments as hoists, lifts, fire extinguishers, etc. All applicable rules and regulations pertaining to workplace health and welfare of workers will be adhered to.

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 cum Group Housing 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 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 operation phase, the total water requirement for the project will be approx. 3587.46 KLD out of which fresh water demand will be 1942 KLD that will be met from HUDA. Therefore, no impact is anticipated on ground water resources due to project as ground water will not be used. Mitigation Measures: The rainwater harvesting will help recharge groundwater aquifer. Treated wastewater from the site will be recycled for landscaping and flushing to reduce demand of freshwater. 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 generated from the project will be collected through the sewer line network provided for plots. Treatment of waste water will be done in Sewage Treatment Plants (STPs) of combined capacity 3200 KLD. Treated effluent from STP will be reused for non-potable purposes. Surplus treated effluent (conforming to CPSB standards) will be discharged to external sewer. Mitigation Measures: No impact is anticipated on the surface water bodies of the region, thus no mitigation measures proposed.

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: 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 residents. 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. DG set of combined capacity 2510 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 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.



Figure 4.1: Wind rose

Mitigation Measures: Green belt and parks will be developed within the premises of project which will attenuate air pollution. LSD/ULSD will be used for DG sets.

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 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 proponent proposes 1, 95,464.37 m2 of green area (30.17% of site area) that will enhance the aesthetic appeal and attract local faunal species. Therefore, 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, more than 1000 persons will get employment opportunities as staff for management, maintenance and security purpose of the colony. As an estimate, more than 5000 persons will get marginal employment as domestic helpers for the residents of the colony. 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, electricity requirement will be met from Dakshin Haryana Bijli Vitran Nigam. Mitigation Measures: To promote energy conservation, it is proposed to provide the buildings with low energy consuming fixtures, maximize availability of natural light, use of solar energy, etc.

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) – fly-ash being a waste product of thermal power plant poses the challenge of disposal. Hazardous in powder form, it is rendered harmless when molded 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 aluminum powder

Fal-G products – are manufactured by use of two waste products being fly ash, calcined gypsum (a byproduct of phosphor-gypsum 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 ferro-cement-sunshade cum lintel etc. Renewable timber

Steel manufactured from recycled content Aluminum manufactured from verified recycled content

Expansion of Residential Plotted Colony (Including Group Housing) “RahejaAranya” EIA/EMP Report Village - Sohna&Raipur, Sector 11 & 14, Chapter V Gurgaon, Haryana


Saw dust based doors and window frames Ferro-cement 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. 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 Residential Colony/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.



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 Plotted &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 projectwill 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 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 Residential Colony/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 thoroughfare 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 Residential Plotted Colony/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 day light, heat, and airflow into a building only when beneficial. The project layout has been finalized after careful siting consideration of various Residential Colony/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 radiationfrom 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 LED lamps instead of GLS lamps for Flats. • Use of LED lamps instead of GLS lamps for Common area. • T5 lamps are used instead of Normal Fluorescent lamps in Basements • Using electronic ballast for Discharge Lamps. • Solar power plant 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 weight 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 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. 2. Remember to help those who may require special assistance--infants, the elderly, and people with disabilities. 3. Stay out of damaged buildings. 4. Use the telephone only for emergency calls.

7.3.2 Response Procedure for Emergency Team 1. Formulate an Emergency Response Team for earthquake response. Using the public address system, inform residents of response procedures discussed above. 2. Inform the necessary authorities for aid. 3. Ensure no person is stuck beneath any debris, in case of a structural failure. 4. Ensure that all occupants standing outside near the buildings are taken to open areas. 5. Ensure that the first aid ambulance and fire tender vehicles are summoned if necessary. 6. Inform the nearby hospitals if there are any injuries. 7. Check the utilities and storage tanks for any damage.

7.4 RESPONSE FOR LPG LEAKAGE 1. The affected area should be evacuated and cordoned off immediately 2. Initiate an Emergency Response Team for LPG leakage. 3. Shut down the main valves in the gas bank. 4. Ensure that only concerned personnel are present in the affected area and all other personnel and visitors are moved to the nearest assembly points. 5. Rescue trapped personnel, also check if any personnel are unconscious in the area and immediately move them outside and provide first aid. Ambulance should be summoned to take injured personnel to the nearest hospital. 6. Personnel in the nearby buildings to close all doors and windows to prevent entry of the leaked gas. 7. Source of leakage to be traced and isolated from all the other areas. And if required use pedestal fans to bring down the gas concentration. 8. In case of a fire follow the instructions in case of fire.

7.5 RESPONSE IN CASE OF FIRE 1. Required response during in the event of a fire should be described in signs located in the lobby.



2. On sighting a fire, it should be immediately informed to the environment manager giving the exact location and type of fire in detail. 3. Initiate the Emergency Response Team for fires. 4. If the fire is small, engage in extinguishing the fire using the nearest fire extinguisher. 5. Guide the Emergency Response Team staff to the emergency assembly point. 6. The Emergency Response Team should immediately inform the nearest dispensary and security force. If required a fire tender should be summoned. 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. 9. If there is too much smoke or fire in the hall, slam the door shut. 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 Residential/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 or through ground water extraction only after valid NOC from CGWA/DC. 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; 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;

Treatment and Recycling: The sullage generated from the sites will be treated in an on-site Sewage Treatment Plant of 3000 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 Residential plotted colony & 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 Expansion of Residential Plotted Colony cum Group Housing Project ‘RahejaAranya’. 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 Residential Plotted Colony cum Group Housing Project, 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.

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 Surface water Hydrology Development & Construction Phase To ensure adequate passage of the storm water as per the regional drainage pattern, water channels will be provided. It is also suggested to avoid excavation during monsoons. Chemicals such as paints and varnishes and oil/ grease will be stored under covered and cemented areas. Wash offs containing these chemicals will be drained into impervious trains for disposal as hazardous wastes.



Post Construction Phase 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 storm water management system of the city and eventually the water bodies but also recharge groundwater. 9.2.3.2 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 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. 9.2.3.3 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 buildings shall be

connected to adjacent drain by a pipe through catch basins. Therefore, it has been calculated to



provide 81rainwater 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 shaft is having adequate diameter

including weep hole, vent pipe and depth. Inside the shaft, a recharge pit of 4 m diameter and 6

m depth is constructed for recharging the available water to the deeper aquifer.

At the bottom of the shaft a filter media is provided to avoid choking of the recharge well.

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 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.

Storm water load (for Commercial area, Common facilities and Group Housing)




Green Area = 1,95,464.37 m2

Paved Area = Site Area – (Ground Coverage + Green Area)

= 6,39,808 – (22,015 + 1,95,464.37)

= 4,22,328.63 m2

Run-off calculation:


= 22,015 x 0.045 x 0.80 = 792.54 m3/hr

Green Area = 1, 95,464.37 m2

= 1, 95,464.37 x 0.045 x 0.1= 879.589m3/hr

Paved Area = 4, 22,329 m2

= 4, 22,328.63 x 0.045 x 0.75 = 14,253.59 m3/hr

Total Runoff Load = (792.54 + 879.589 + 14,253.59) m3/hr = 15925.719 m3/hr

Taking 20 minutes retention time, total volume of storm water will become = 15925.719/3

= 5308.573 m3

Taking the effective diameter and depth of a RWH pit as 4 m and 6 m respectively, volume of

RWH Pit will be =πr2h = 3.14 x 2 x 2 x 6

= 75.36 m3

Hence, no. of pits required = 5308.573/75.36 = 70 pits

Total of 70 Rain Water Harvesting pits are proposed for artificial ground water recharge.

For residential plots, individual plot owners will make their own arrangement for rain water

harvesting.



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. 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. 2590 KLD of wastewater including existing

and expansion part. The wastewater will be treated in onsite STP (s) of combined capacity 3000

KLD (500*6 based upon occupancy). The treated effluent from STP will be approx.2072 KLD

which will be reused for flushing, horticulture and surplus will be discharged to external sewer.

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.



9.2.4 Air Quality 9.2.4.1 Development and Construction Phase The construction phase for the group housing colonyis about 2-3years, causing only marginal impact on ambient air quality from constructional activities, unloading of construction materials, cement, soil and vehicular movement etc. The main pollutant of concern is PM 2.5, PM10 (dust). Likewise, following mitigation measures will be adopted during this phase to mitigate the impacts on ambient air:

Installation of batch plant at isolated place and providing cover shed around plants.

Loading and unloading of cement and other material in covered shed. Providing dust suppression system in unloading area (as per requirement). Developing avenue and curtain plantation on the internal roads and peripheral

plantation around the site to protect the movement of dust and other pollutants. Cover scaffolding, hosing down road surfaces and cleaning of vehicles. On-Road- Inspection for black smoke generating machinery. Vehicles having pollution under control certificate will be allowed to ply. Use of covering sheets for trucks to prevent dust dispersion from the trucks. Reducing the speed of a vehicle to 20 km/hr to reduce emissions on site. All material storages will be adequately covered and contained. Training to the workers to reduce idling time of machines that otherwise tends to

produce hydrocarbons ad carbon monoxide. Best practices for maintenance and repair of all machineries and equipment’s.

9.2.4.2 Post Construction Phase During the post construction phase, following measures will be adopted for pollution control in the Expansion of Residential Plotted Colony cum Group Housing Project ‘Raheja Aranya’:

Adequate stack height for DG Sets Traffic pollution management Plantation development

DG Sets:There is provision of DG sets of combined capacity 2510 kVA for power back up of

essential facilities of the project.

The DG sets will be equipped with acoustic enclosure to minimize noise generation and adequate

stack height will be provided as per CPCB norms for proper dispersion of emissions.



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 Expansion of Residential Plotted Colony cum Group Housing Project ‘Raheja Aranya’. Suggested species for plantation are:

Cassia Fistula(Amaltas) Bauhinia purpurea (Kachnar) Saraca asoca (Sita ashok) Astonia scholaris (Scholar tree)

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.



Barriers: Trees having thick and fleshy leaves with flexible petioles having capacity to withstand vibration are suitable. Heavier branches and trunk of the trees also deflect or refract the sound waves. The following species are proposed to be used in a greenbelt especially surrounding housing groups and along the periphery of the project.

Saraca asoca (Sita Ashok) Cassia fistula (Amaltas) Astonia Scholaris (Scholar Tree) Bauhinia variegated(Kachnar)

9.2.7 Biological Environment 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. 31% area of total area is proposed to be maintained green in the project site.

CHAPTER-10

SUMMARY AND CONCLUSION

10.1 PROJECT BACKGROUND M/s Raheja Developers Ltd. intends to construct the Expansion of Residential Plotted Colony cum Group Housing Projectat Village-Sohna& Raipur, Sector-11 & 14, Gurgaon.As per EIA Notification, 2006 & its amendments for all Group Housing and area development projects covering an area of 50 ha and/ or built up area greater than 1, 50,000 m2 are designated as category 8 (b) projects and are required EIA Report to obtain prior environmental clearance from respective State Environmental Impact Assessment Authority (SEIAA). The project is thus categorised as 8(b) under Schedule of the Environmental Impact Assessment Notification and requires Environmental Clearance from the State Environment Impact Assessment Authority, Haryana since the up area is 2,54,526.299 m2 So, EIA/EMP study is required. The EIA/EMP study has been carried out by Grass Roots Research & Creation India Pvt. Ltd.

For this study, the impact zone shall confine within an angular radius of 5 km from the project boundary. For the purpose of certain environmental components, the radius has extended up to 10 km as well. The EIA is conducted to establish the baseline environmental setting in the study area, assessment of potential impacts on different environmental components, design of mitigation measures so as to keep impacts within acceptable limits and strengthen the positive impacts. The Executive Summary summarizes the findings of the EIA study to aid in decision making and provides project related information and environmental impacts to non-technical sections of society. The summary highlights the baseline environmental status, key environmental issues and their likely impacts and also lists the major recommended mitigation measures to attenuate the impacts. 10.2 PROJECT SITE& CONNECTIVITY The project is located at Village-Sohna & Raipur, Sector-11 & 14, Gurgaon, Haryana. The

project site is well connected through NH-71 B. The nearest railway station is Asoti Railway

Station, which is approx. 25.30 km away from the project site towards (NE). The nearest airport

is Indira Gandhi International Airport, approx.37.39 km (N) from the project site.



PROJECT FEATURES

The design population of the site is 25,909. Salient features of the project are: Table 10.1:Salient Features of the project

S. No. Facility Values 1. Power Supply 17.3 MW 2. D.G. Set combined capacity 2510 kVA 3. Parking Required – 1230 ECS (As per

MoEFCCnorms) Proposed – 1235 ECS

4. Water Supply Operational Phase: HUDA Construction Phase: Treated water from nearby STP (HUDA)

5. Water Demand Fresh water- 1984.46 KLD 6. Sullage generation 2590 KLD 7. STP Capacity 3000 KLD (500*6 based upon occupancy) 8. Solid waste generation 11433.5 kg/day 9. Manpower requirement 150-200 persons

The project will be implemented over a span of two to three years from the commencement of construction. 10.3 ENVIRONMENTAL SETTING OF THE STUDY AREA The baseline environmental status was assessed based on primary and secondary data collected either through in-site field observation or obtained from agencies such as 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. The baseline status established from analysis of secondary and primary data and predicted impacts are discussed below. The proposed mitigation measures are also provided along with. 10.3.1 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 12,139kg/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. 10.3.2 Water environment The project site is located at Village-Sohna& Raipur, Sector-11 & 14, 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 3000 KLD (500*6 based upon occupancy) capacity will be set up to treat waste water. 10.3.3 Air Environment During construction phase, the major air pollutant of prime concern is PM2.5, PM10 as 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 of combined capacity 2510 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. 10.3.4 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 equipment’s 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. 10.3.5 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 1, 95,464.37 m2i.e30.17% 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, Aegle marmelos, Adina cordifolia and ornamental shrubs like Bambusa arundinacia, Bambusa vulgaris have been proposed to be planted inside the premises.

The execution of the project will not disturb the people living in area as there will be no blasting and large scale digging. The project will generate employment opportunities for both skilled and unskilled workers in the vicinity, which will produce multiple effects on the life and economy of the local people. Thus from socio-economic point of view the project is beneficial to the people and can be executed with little hesitation. 10.3.7 Energy efficiency The power shall be supplied by Dakshin Haryana BijliVitran Nigam (DHBVN). The total

connected load for the project will be approx. 17.3 MW.

The project will have power back up from D.G. sets of combined capacity of 2510kVA There is

provision of DG sets of combined capacity 2510 kVA for power back up in the Expansion of

Residential Plotted Colony cum Group Housing Projectare proposed to provide backup in case of

power failure. Various provisions are made to reduce the energy efficiency of the building, such

as use of solar energy, provision of low energy fixtures, design features to maximise sunlight and

use of materials to improve energy efficiency.

10.3.8 Others Resource Conservation: A concerted effort is made towards resource conservation by way of using recycled building materials, reduced water consumption and improving energy efficiency of the building.



Indoor Air Quality: Special attention will be given to maintaining indoor air quality through use of low VOC paints, provision of adequate ventilation, proper storage of chemical and cleaning materials. Safety:A network of manned security gates, security men, closed circuit TV and intercom facilities are proposed to ensure safety of the occupant. The buildings will also be provided with adequate fire tenders, fire alarms and water sprinklers. 10.4 ENVIRONMENTAL MANAGEMENT PLAN Adequate environmental management measures will be incorporated during the entire planning, construction and operating stages of the project to minimize any adverse environmental impact and assure sustainable development of the area. For the effective and consistent functioning of the campus, an Environmental Management System (EMS) will be established at the site including an Environmental Management cell for implementation of the EMP and monitoring plan, training and awareness, audits and maintenance of records. The total estimated cost of the Group Housing Colony is Rs. 480Crores which includes the cost of the land as well as the developmental cost.

Based on the environmental assessment, the associated potential adverse environmental impacts can be mitigated to an acceptable level by adequate implementation of the measures as stated in the EIA and the EMP. Some of the benefits from the project are:

Use of solar energy for street lighting Provision of green walls and green terraces Use of CLC blocks (containing approx. 33% flyash) Use of steel manufactured from recycled content. Provide permeable paving to control surface water runoff Rainwater harvesting Meet all requirements for buildings in moderate earthquake prone areas. Provision of fire alarms and water sprinklers. Provision of welfare schemes to workers. Extending educational and healthcare facilities to the local people. Commitment to engaging local people and businessmen for maintenance and

repair work.



Hence, it may be concluded that the project will have significant positive economic and social impact on the local community apart from meeting the housing needs of the occupants, without bearing any significant adverse environmental impact.
