On assumption that since project is granted environment clearance under 8(b) activity which

covers the project having built-up area more than 1,50,000 sq m (no closing limit), they

considered that some extra construction will automatically be covered in this clearance M/s

Raheja Developers Ltd. has not applied for revised environment clearance to SEIAA, Haryana

initially for some increase in built-up area and modifications in the plan while they have made

provisions of all environmental requirements for increased levels as per the EC. Later M/s

Raheja Developers Ltd on realizing requirement of obtaining re-environment clearance, have

applied for revised environment clearance for expansion of the project to SEIAA, Haryana vide

letter dated 26.10.2015 as per modified planning without undertaking the increased construction.

Due to long with period of grant of clearance for increased built-up M/s Raheja Developers Ltd

has continued the construction at the site as per modified planning in anticipation that the work

can be conducted on the basis of EC granted for project in 2009 and application for re-

environment clearance for expansion is already in process. The intent was to expedite the

construction and optimize the time and money. Though above construction falls under violation

category, M/s Raheja Developers Ltd has not completely constructed the project as per modified

planning and status of the construction carried out till date as per modified planning is given in

Table 3 below.

1.7 Water Requirement

Water requirement during construction phase is app. 50-60 KLD. Source of water during

construction is treated water from nearby CSTP of HUDA (at Manesar). Source of water during

operation phase is HUDA supply supplemented by private water tankers. Total water

requirement for the project is 732.68 KLD out of which 610 KLD is domestic water requirement,

122.68 KLD is horticulture water requirement and 44 KLD is used for road and car washing

during non rainy season. Fresh water requirement is 427 KLD and recycled water requirement is

349.68 KLD. Detailed water calculations are given in Table 8. Water balance diagram are given

in Figure 5 & 6.

1.8 Sewage Generation

Sewage generation from the project site is expected to be 525 KLD which should be treated in

STP of capacity 630 KLD. STP of 550 KLD is already constructed at the site and is operational.

Remaining 80 KLD of STP will be constructed as second module. Treated water from the STP is

being used for flushing, horticulture and road &car washing. Remaining treated water is used for

construction at the site or can be given to nearby construction sites or can be disposed off in

sewer. STP with the SAF (Submerged Aerated filter) technology is constructed at the site and

same technology will be adopted for expansion. STP is open to air. Water is treated upto tertiary

level in the STP. Details of sewage treatment methodology and process are given in section 1.9.

Detail of sewage generation and STP capacity is mentioned in Table 8. Characteristics of the

sewage are given in Table 9.

1.9 Sewage Treatment Process (SAF)

SAF is an extremely efficient and well-proven biological treatment process which is used

to biodegrade organic matter. It can also reduce nitrogen in the wastewater to deliver a treated

wastewater that exhibits a very high level of BOD, COD and Nitrogen reduction along with high

levels of reduction in suspended solids. The SAF could be described as a “box of media”. It

utilizes a rigid, corrugated, structured polypropylene media to give a high surface area for

biomass attachment. The media is arranged into cells-in-series where effluent is contacted with

the fully submerged media in the presence of co-current aeration. Air is supplied by two low-

maintenance regenerative blowers. Air enters the process below the media via fine bubble

membrane diffusers. A secondary clarifier tank follows the SAF for removal of any biomass that

sloughs off the media during operation. Biological phosphorus and nitrogen removal can be

achieved with the SAF since the design incorporates sequential staged operations as required for

BNR flow schemes. Phosphorus removal utilizes the anaerobic, balance tank (septic tank) used

prior to the SAF. Recycled sludge from the final clarifier is mixed with the influent in this stage.

Nitrogen removal is then achieved via denitrification in the first cell of the SAF where, with no

air injected, and the introduction of recycled nitrified effluent from the end of the process, the

process becomes anoxic. The latter SAF cells are fully aerated and BOD removal and

nitrification are achieved in these. Full BNR requires a fourcell SAF, minimum. Typically

effluent from a full BNR scheme will be:

BOD less than 10 mg/l

Total nitrogen less than 5 mg/l

Ammonia nitrogen less than 1 mg/l

Total phosphorus less than 0.5 mg/l

Process:

Raw sewage from the sewage pump station is pumped through the inlet works of the WWTP

where it undergoes screening for removal of inorganics prior to entering the balance tank. The

balance tank provides a buffer against peak inflows and provides a steady inflow to the

downstream process. Prior to entering the treated effluent storage tank the effluent may be

filtered (to achieve Class A quality). The treated effluent is stored in the irrigation tank prior to

discharge to the irrigation field or re-use, whichever is applicable.

Conceptual Plan



20


Inlet Works

All raw sewage is pumped to the inlet works of the waste water treatment plant. A mechanical

screen is installed to remove all the inorganic material from the sewage and dispose it to the

waste bin below.

Balance Tank

The Balance Tank is designed to handle peak flows and allow a pre-determined and controlled

flow for subsequent treatment. The waste water is temporarily stored in the Balance Tank before

being pumped by a submersible Balance Pump to Primary Tank 1. The flow rate is set using the

flow control valves located in the Balance Tank. Excess flow is returned to the same tank.

The Balance Tank level is regulated by 3 float-type level switches. A coagulant is dosed into the

discharge of the Balance Pump by the Coagulant Dosing Pump whenever the Balance Pump

runs. The coagulant assists both in aiding the settlement of settleable solids in the plant and in

reducing the phosphorous level in the treated effluent. The Coagulant Dosing pump draws from a

bunded carboy of coagulant.]

Primary Tanks

Primary Tank 1 provides additional buffer capacity of inlet flow whilst Primary Tank 2 creates a

steady inflow for the Anoxic and the Aerobic Tanks. After the waste water is delivered to

Primary Tank 1, the top water level of the influent waste water is allowed to overflow into

Primary Tank 2. Both tanks encourage sedimentation of between 30 and 50% of the influent

suspended solids and allow anaerobic digestion to take place.

In anaerobic waste water treatment, bacteria digest organic material in the absence of oxygen and

transform part of the sludge to gases such as methane and carbon dioxide. In this design, the

anaerobic treatment occurs in Primary Tank 1 and Primary Tank 2.

Anoxic Tank

The top water level of the influent waste water is allowed to overflow from Primary Tank 2 to

the Anoxic Tank. The Anoxic Tank allows nitrate-specific bacteria to use nitrate (NO3) as an

oxygen source and a nutrient in a process called denitrification. This activity helps to remove

nitrogen based pollutants such as urea and ammonia by converting them into nitrate and nitrite

before releasing them as nitrogen gas into the atmosphere. The tank is enriched with returned

activated sludge (RAS) from the Clarifier to provide a plentiful supply of food for the bacteria.

The partially treated effluent from the Anoxic Tank contains approximately 65% of the pollution

load of the original sewage influent entering the waste water plant.

Aerobic Tank

The top water level of the influent waste water is allowed to overflow from the Anoxic Tank to

the Aerobic Tank where it is aerated. Air is introduced into the Aerobic Tank by the Biological

Air Blower through air diffusers located beneath a submerged media. Coarse air bubbles provide

favourable conditions for the growth of aerobic bacteria.

The Aerobic Tank which contains the submerged media has a large surface area, allowing

bacteria and other micro-organisms to thrive and form a biological film. These micro-organisms

Conceptual Plan



21


utilise the dissolved oxygen in the air bubbles in the waste water to consume dissolved matter

and by so doing remove a majority of the colloidal contaminants present in the waste water by

converting them into carbon dioxide and biological floc.

Floc is then allowed to settle in the Clarifier from where it is removed, thereby reducing the

accumulation of sludge. Friction from the coarse air bubbles further serves to scour and release

dead biomass from the media. This Aerobic Tank is partially divided by a baffle so as to prevent

under-aerated waste water from prematurely moving to the next stage in the treatment process.

This baffle also serves to alter the flow direction such that the partially treated waste water will

make intimate contact with the submerged media before entering the Clarifier.

Clarifier

The Clarifier removes heavier solids by means of settlement and separation from the liquid

phase. It is designed to have a large surface area with adequate retention time. The hopper

bottom channels the sediment to the centre of the Clarifier tank before the sediment is returned to

Primary Tank 1.

Clear liquor from the top of the Clarifier is decanted into the Chlorine Contact Tank. In this

process, clarification and thickening happen at the same time. Separation of solids from the

liquid stream occurs to produce a clarified effluent with low suspended solid levels. From

thickening, the conveyance of sludge particles to the bottom of the tank results in a

slightly concentrated underflow, known as return activated sludge (RAS).

Chlorine Contact

The top water level of the influent waste water is allowed to overflow from the Clarifier to the

Chlorine Contact Tank. The Chlorine Contact Tank contains chlorine in tablet form and it is

designed to provide 30 minutes minimum contact time for effective disinfection of the influent

with chlorine, a powerful disinfectant.

This is a process whereby chlorine compounds are added to the treated waste water for the

purpose of pathogen reduction. Calcium hypochlorite tablets are in constant contact with the

effluent to ensure that the effluent is safe for disposal.

Media Filter

A media filter is required to meet the quality to re-use it again. Before reaching the Irrigation

Tanks the effluent is filtered using a Media Filter which will remove particles above 10 microns

in size. When the pressure drop across the Media Filter reaches a pre-determined set point the

Media Filter is automatically backwashed by the Media Filter Backwash Pump which draws

water from the Irrigation Tank with the dirty backwash wash water going back to the Balance

Tank.

1.14 Green Area

Total green area measures 20,447 m2 i.e. 35.7 % of the net plot area is planned to be kept under

green cover. At present, 17,385.1 sq m of area is already under green cover at site. Evergreen

and native species are preferably planted at the project site. Native species are adapted to natural

conditions and also requires less aftercare and maintenance. Trees with large & round canopy are

planted. Plantation act as noise buffer and also provide surface for dust settlement. Green belt

development plan for the area is given below

Green Belt development Plan

All the developments are associated with the pollution of one or more environmental component.

Plants are the natural sink of that pollution. Plants help in abatement of the pollution and restore

the degraded environment. Green belt lowers down the air pollution by providing a surface to

settle down or by absorbing the pollutants, attenuate noise level and uses the waste water. Phyto-

remediation is one of the most successful available technologies of restoring the degraded

environment. For this project area of 20,447 m2

is proposed to be put under green cover. Green

cover will comprise of:

A peripheral green belt

Avenue plantation (along road)

Lawns/parks & grass cretes/pavers

Planters

Conceptual Plan



28


Selection of Plant Species for Green Belt Development

Selection of plant species for the development depends on various factors such as climate,

elevation and soil. The plants would exhibit the following desirable characteristics in order to be

selected for plantation

1. Species should be fast growing and providing optimum penetrability with minimal

maintenance. Perennial, evergreen & fast growing trees

2. Species should be wind-firm and deep rooted

3. Indigenous and locally available species will be planted

4. Trees with high foliage density, leaves with larger leaf area and hairy on both the surfaces.

Round, thick & spreading canopy is preferred for peripheral green belt and oblong canopy

for road side plantation

5. Ability to withstand conditions like inundation and drought

6. Soil improving plants (Nitrogen fixing rapidly decomposable leaf litter)

7. Bird and insect attracting tree species

8. Tolerant to climatic conditions of the area and with less water requirement & after care will

preferable be planted. Species tolerance to air pollutants like SO2 and NO2 should be

preferred

9. Plantation trees with ornamental foliage & shrubs with fragrant flowers will enhance scenic

beauty of the area. Attractive appearance with good flowering and fruit bearing

10. Plantation should be such that it maintains ecological & hydrological balance of the region.

Trees and shrubs to be planted at project site as per CPCB guidelines for green belt development

are given below in Table 15 below
