Scope of Work of EIS“...The EIS shall cover the following:

Description of the proposed project:The first task:” Description of the proposed project” forms a vital component of theEnvironmental Impact Statement (EIS) as it provides the basis for evaluating the likelycauses of Environmental Impacts. Land use issues dictate the significance of landloss/change. It is essential that the key components of the project shall be clearlydetermined as far as possible at this stage.

Assessment of Environmental Impacts:Based upon the results from the review of existing information, field visits, site datacollection and consultation, for each component of environment (physical, biologicaland socio economic) the positive, negative, direct and indirect, temporary andpermanent impact s will be evaluated along with an indication of the degree of impact,i.e., whether the impact is significant, moderate, minor or negligible.

Environment Management Plan and Mitigation Plan:For each significant negative impact identified, specialist shall work closely with theengineering team/technical consultants to suggest practicable measures to avoid ormitigate the impact. Suggestions for compensation shall be given where there is noother alternative course of action.

The mitigation of environmental impacts will be by three mechanisms.=>Introduction of mitigation features through the engineering practices.

=>Implementation of environmental controls during construction and operation.

=>Legislative control involving compliance with Indian environmental laws.

The Environmental management plan shall include an estimate of capital and recurringcosts of mitigation measures and will identify the parties and institutional frameworkfor implementation.

Monitoring Plan:Having identified the significant environmental impact that are likely to arise as a resultof the Residential Apartments construction project, the project team shall specify whatmonitoring is required during the various phases of the project cycle.The monitoring plan will identify parameters and frequency of monitoring andresponsible organization.

Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technologyPROCESS DESCRIPTION:The raw sewage will be collected in a collection sump and pumped to mechanical barscreen chamber for removal of large floating matter followed by grit removal in GritChamber. The raw sewage will then be collected in an equalization tank forhomogenization of hydraulic load. The tank contents will be kept in suspension bymeans of course bubble serration through pipe grid. The equalization tank, with airflow indicator for continuous monitoring of air supply to the tank in order to avoidseptic conditions, will be covered from top (RCC or FRP) to avoid nuisance. Theequalized effluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) inseries where BOD/COD reduction can be achieved by virtue of aerobic microbialactivities. The oxygen required will be supplied through coarse air bubble diffusers.The bio-solids formed in the biological process will be separated in the down streamTube Settler. The clear supernatant will gravitate to the chlorine contact tank wheresodium hypochlorite will be dosed for disinfection of treated water prior to disposal.

The biological sludge generated in the FAB and settled in the tube settlers will becollected in a sludge sump and then pumped to sludge drying bed for de watering. Thedried sludge will then be disposed off suitably as manure. The schematics of theprocess are shown. The two main components of the treatment system viz. The FABreactor and tube settler are described in the following sections.

Fluidized Aerobic Bio Reactor (FAB)Conventional effluent treatment plants are large sized, power intensive and require alot of monitoring. Scarcity of open space and rising land a power costs have forced theindustries to look our for space saving, compact and efficient treatment options. Thishas led to the development attached growth processes where the bio mass is retainedwithin the aeration tank obviating the need for recycle. These plants are not onlycompact but also user friendly. The endeavor to have a continuously operating, no-clogging biofilm reactor with no need for back washing, low head-loss and high specificbiofilm surface area culminated in the most advanced technology of aerobic biologicalfluidized bed treatment where the biofilm (biomass) grows on small carrier elementsthat move along with the water in the reactor. The movement is normally caused byaeration in the aerobic version of the reactor.The reactor combines all the advantages and best features of Trickling filters, Rotatingbiological contractors, activated sludge process and submerged fixed film reactorswhile eliminating the drawbacks of these systems. The plants are more compact andmore energy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up withsmall carrier elements. The elements are made up of special grade PVC orpolypropylene of controlled density (shown in plate). For media of specific gravity 0.92-0.96 the overall density could be expected to increase up to 9.5% when full of biomasssuch that they can fluidize using an aeration device. A biofilm develops on the

A - 5

elements, which move along the effluent in the reactor. The movement within thereactor is generated by providing aeration with the help of diffusers placed at thebottom of the reactor. Then thin biofilm on the elements enables the bacteria to actupon the biodegradable matter in the effluent and reduce the BOD/COD content in thepresence of oxygen available from the air that is used for fluidization.

2.6 What is the incremental pollution load from wastewater generated from theproposed activity? (Give details of the quantities and composition of wastewatergenerated from the proposed activity)



The sewage shall be treated and reused for flushing and on land irrigation. The treatedsewage shall meet the standards for disposal into surface water bodies, and hence thereshall not be any major additional load on the sewer lines, and may facilitate dilution of thesewage. The quantity of sewage expected is in the order of 121.4 KL/day.

2.7. Give details of the water requirements met from water harvesting? Furnish details ofthe facilities created.

The storm water drain would also ensure that the sedimentation does not occur, asrainwater harvesting structures will also help in controlling the sedimentation. Therainwater harvesting system proposed would enhance the water retention and increasesthe water table. The drainage would in effect reduce the runoff and increase thepercolation. The gradient of the channel will be maintained throughout its length so thatwater does not pond within it. Flows will be maintained at velocities that will scour thechannel of debris. For instance, runoff velocities should not be less than 1 m/s nor shouldthey exceed 3 m/s. Based on the catchment area, potential inflows and rainfall intensity,determine the drain size so as to minimize damage resulting from high intensity storms.Energy dissipaters such as drop structures will be provided along the channel where runoff

F IA - 9

velocities may become excessive. The overflow from the storm water drains at rainwaterharvesting structures shall be provided with an overflow channel to drain into the roadsideplantation which will act as a bios wale. Typical drawings of rainwater harvestingstructures are presented for roof areas. The rainwater harvesting structures is presentedbelow.

2.8.What would be the impact of the land use changes occurring due to the proposedproject on the runoff characteristics (quantitative as well as qualitative) of the area in thepost construction phase on a long term basis? Would it aggravate the problems offlooding or water logging in any way?

The impact of housing project on physiography is a function of the terrain of the area. It ismost drastically altered in case of hilly terrain or where extensive cut-and-fill operationsare involved. The project area has a rocky terrain and the design stage deliberations haveensured that the major contours are not disturbed. However the physiography impact will

F IA - 10

be significant and non-reversible, as the contours of the area will be disturbed. The cutand fill operations may cause air pollution, clogging of drains and solid waste for disposal.The design stage has optimized the cut and fill operations and the excess cut material isminimum and the same shall be reused for the construction purposes.The project will have a positive impact on the soils and soil quality as housing project willhave landscaping and the soils will be protected due to conservation.

During the occupation stage, compaction will not occur, and the compaction if any will berestricted to road ROW. And the road ROW compaction cannot be said to be an impact ofthe operation stage as the pavement itself is a function of compacted base and sub base.

During the occupation stage, soil pollution due to garbage dumping at unauthorizedlocations may have temporary negative impact leading contamination of soil. Theaccidental spills or leaks are also a low probability incident.

The other major impact will be due to the increased run off and may have negative impacton the receiving body if the same is not properly managed. Impacts due to surface runoffinclude increased soil erosion and local flooding or water logging. Hence the project will bedesigned with adequate storm water drains and cross drainage structures. The housingactivity will be provided with a Sewage treatment plant to treat the domestic wastewaterand necessary infrastructure will be provided for the safe disposal of domestic wastes toprotect the water bodies.

2.9.What are the impacts of the proposal on the ground water? (Will there be tapping ofground water; give the details of ground water table, recharging capacity, and approvalsobtained from competent authority, if any)

Ground water shall be used as a secondary source during non-availability of water fromHMWSSB. The ground water table is at a depth of 10m to 15m

2.10.What precautions/measures are taken to prevent the run-off from constructionactivities polluting land & aquifers? (Give details of quantities and the measures taken toavoid the adverse impacts)

Construction activity is taken up only during non-monsoon season. There are no majordrains in the site. All material dumps shall be located away from the natural drains.Storm water drains shall be constructed before the construction of the buildings.

2.11. How is the storm water from within the site managed?(State the provisions madeto avoid flooding of the area, details of the drainage facilities provided along with a sitelayout indication contour levels)

Storm water drains will be provided all over the site to meet the expected increase in therunoff during rainy seasons due to the impervious nature of the roads and other pavedareas. It is proposed to maintain the levels as much as possible before letting storm waterinto side drains of main road.

Based on the catchment area, potential inflows and rainfall intensity, determine the drainsize so as to minimize damage resulting from high intensity storms. Energy dissipaterssuch as drop structures will be provided along the channel where runoff velocities maybecome excessive. The overflow from the storm water drains at rainwater harvesting

F IA - 11

structures shall be provided with an overflow channel to drain into the roadside plantation,which will act as a bioswale.

Strom water drains: Storm water drains will be provided all over the site to meet theexpected increase in the runoff during rainy seasons due to the impervious nature of theroads and other paved areas. It is proposed to maintain the levels as much as possiblestorm water is letting into side drains of main road. The expected runoff is calculated forthe entire site is mentioned below.

(Give details of the quantities of wastewater generation, treatment capacitieswith technology & facilities for recycling and disposal)All Apartments and Community center shall be provided with appropriate plumbing fortransfer of sewage to the sewage treatment plant.

Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technologyPROCESS DESCRIPTION:The raw sewage will be collected in a collection sump and pumped to mechanical barscreen chamber for removal of large floating matter followed by grit removal in GritChamber. The raw sewage will then be collected in an equalization tank forhomogenization of hydraulic load. The tank contents will be kept in suspension bymeans of course bubble serration through pipe grid. The equalization tank, with airflow indicator for continuous monitoring of air supply to the tank in order to avoidseptic conditions, will be covered from top (RCC or FRP) to avoid nuisance. Theequalized effluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) inseries where BOD/COD reduction can be achieved by virtue of aerobic microbialactivities. The oxygen required will be supplied through coarse air bubble diffusers.The bio-solids formed in the biological process will be separated in the down streamTube Settler. The clear supernatant will gravitate to the chlorine contact tank wheresodium hypochlorite will be dosed for disinfection of treated water prior to disposal.

The biological sludge generated in the FAB and settled in the tube settlers will becollected in a sludge sump and then pumped to sludge drying bed for de watering. Thedried sludge will then be disposed off suitably as manure. The schematics of theprocess are shown. The two main components of the treatment system viz. The FABreactor and tube settler are described in the following sections.

Fluidized Aerobic Bio Reactor (FAB)Conventional effluent treatment plants are large sized, power intensive and require alot of monitoring. Scarcity of open space and rising land a power costs have forced the

F IA - 13

industries to look our for space saving, compact and efficient treatment options. Thishas led to the development attached growth processes where the bio mass is retainedwithin the aeration tank obviating the need for recycle. These plants are not onlycompact but also user friendly. The endeavor to have a continuously operating, no-clogging biofilm reactor with no need for back washing, low head-loss and high specificbiofilm surface area culminated in the most advanced technology of aerobic biologicalfluidized bed treatment where the biofilm (biomass) grows on small carrier elementsthat move along with the water in the reactor. The movement is normally caused byaeration in the aerobic version of the reactor.The reactor combines all the advantages and best features of Trickling filters, Rotatingbiological contractors, activated sludge process and submerged fixed film reactorswhile eliminating the drawbacks of these systems. The plants are more compact andmore energy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up withsmall carrier elements. The elements are made up of special grade PVC orpolypropylene of controlled density (shown in plate). For media of specific gravity 0.92-0.96 the overall density could be expected to increase up to 9.5% when full of biomasssuch that they can fluidize using an aeration device. A biofilm develops on theelements, which move along the effluent in the reactor. The movement within thereactor is generated by providing aeration with the help of diffusers placed at thebottom of the reactor. Then thin biofilm on the elements enables the bacteria to actupon the biodegradable matter in the effluent and reduce the BOD/COD content in thepresence of oxygen available from the air that is used for fluidization.

9.4.What passive solar architectural features are being used in the building? Illustrate theapplications made in the proposed project.

The width to height ratio between the apartment blocks is around 1:1.5 which isachieved as per the development control rules.

All window openings is provided with chajjas depth as specified by the designstandards (around 300mm)

The full height openings have been designed for better lighting in the apartmentsunits. For climatic considerations, all these openings are placed next to abalcony/sit out space which acts as a buffer by eliminating the direct lighting andthereby avoiding heat ingress.

Use of Large fenestrations in buildings reduces the use of mechanical light energyduring daytime thereby reducing the energy consumption.

9.5.Does the layout of streets & buildings maximize the potential for solar energydevices? Have you considered the use of street lighting, emergency lighting and solar hotwater systems for use in the building complex? Substantiate with details.

9.7. Do the structures use energy-efficient space conditioning, lighting and mechanicalsystems? Provide technical details. Provide details of the transformers and motorefficiencies, lighting intensity and air-conditioning load assumptions? Are you using CFCand HCFC free chillers? Provide specifications.

Building Materials

The building materials chosen for the landed and apartment units are as per therecommendations of the climatic standards.

To achieve the maximum energy value, a balance between the availability ofbuilding materials locally and skilled labourers is achieved.

Burnt brickwork with fly ash for the walling and plastering reduces the thermalpenetration by 20-30%.

Colour of Facades The colour choice for the buildings uses a maximum of white surface (nearly 84%).

This increases the solar reflectivity factor. Emittance factor for white surfaces is around 90% compared to coloured surface

(20-60%)

F IA - 29

16% of wall area uses earthen colours and this space has longer thermal storage inthe walls. This creates a comfortable temperature at nights due to the thicker wallsdesigned.

Heat Absorbance of the brick used for building is around 50%. The roof of the units (if not covered with terrace garden) is painted white to have a

maximum reflectivity. The R-factor (resistance factor) for the roof with brickbats and white painted is

nearly 40% more as compared to the recommended standards.

9.8.What are the likely effects of the building activity in altering the microclimates?Provide a self-assessment on the likely impacts of the proposed construction on creationof heat island & inversion effects?

Green RoofsGreen roofs are an attractive roofing option that can reduce urban heat islands byproviding shade and through evapotranspiration, the release of water from plants to thesurrounding air. The benefits of green roofs include:

Reduce sewage system loads by assimilating large amounts of rainwater. Absorb air pollution, collect airborne particulates, and store carbon. Protect underlying roof material by eliminating exposure to the sun's ultraviolet

(UV) radiation and extreme daily temperature fluctuations. Serve as living environments that provide habitats for birds and other small

animals. Offer an attractive alternative to traditional roofs, addressing growing concerns

about urban quality of life. Reduce noise transfer from the outdoors. Insulate a building from extreme temperatures, mainly by keeping the building

interior cool in the summer.
