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 Independent Villa 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 by meansof course bubble serration through pipe grid. The equalization tank, with air flowindicator for continuous monitoring of air supply to the tank in order to avoid septicconditions, will be covered from top (RCC or FRP) to avoid nuisance. The equalizedeffluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) in series whereBOD/COD reduction can be achieved by virtue of aerobic microbial activities. The oxygenrequired will be supplied through coarse air bubble diffusers. The bio-solids formed in thebiological process will be separated in the down stream Tube Settler. The clearsupernatant will gravitate to the chlorine contact tank where sodium hypochlorite will bedosed 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 the processare shown. The two main components of the treatment system viz. The FAB reactor andtube settler are described in the following sections.

Fluidized Aerobic Bio Reactor (FAB)Conventional effluent treatment plants are large sized, power intensive and require a lotof 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. This hasled to the development attached growth processes where the bio mass is retained withinthe aeration tank obviating the need for recycle. These plants are not only compact butalso user friendly. The endeavor to have a continuously operating, no-clogging biofilmreactor with no need for back washing, low head-loss and high specific biofilm surfacearea culminated in the most advanced technology of aerobic biological fluidized bedtreatment where the biofilm (biomass) grows on small carrier elements that move alongwith the water in the reactor. The movement is normally caused by aeration in theaerobic 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 reactors whileeliminating the drawbacks of these systems. The plants are more compact and moreenergy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up with smallcarrier elements. The elements are made up of special grade PVC or polypropylene ofcontrolled density (shown in plate). For media of specific gravity 0.92-0.96 the overalldensity could be expected to increase up to 9.5% when full of biomass such that they canfluidize using an aeration device. A biofilm develops on the elements, which move alongthe effluent in the reactor. The movement within the reactor is generated by providingaeration with the help of diffusers placed at the bottom of the reactor. Then thin biofilmon the elements enables the bacteria to act upon the biodegradable matter in the

effluent and reduce the BOD/COD content in the presence of oxygen available from theair that is used for fluidization.

2.6. Give details of the water requirements met from water harvesting? Furnishdetails of the 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 andincreases the water table. The drainage would in effect reduce the runoff and increasethe percolation. The gradient of the channel will be maintained throughout its length sothat water does not pond within it. Flows will be maintained at velocities that will scourthe channel of debris. For instance, runoff velocities should not be less than 1 m/s norshould they exceed 3 m/s. Based on the catchment area, potential inflows and rainfallintensity determine the drain size so as to minimize damage resulting from highintensity storms. Energy dissipaters such as drop structures will be provided along thechannel where runoff velocities may become excessive. The overflow from the stormwater drains at rainwater harvesting structures shall be provided with an overflowchannel to drain into the roadside plantation which will act as a bios wale. The typicalcross section is presented below.

2.7. 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 inthe post 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. Itis most drastically altered in case of hilly terrain or where extensive cut-and-filloperations are involved. The project area has a rocky terrain and the design stagedeliberations have ensured that the major contours are not disturbed. However thephysiography impact will be significant and non-reversible, as the contours of the areawill be disturbed. The cut and fill operations may cause air pollution, clogging of drainsand solid waste for disposal. The design stage has optimized the cut and fill operationsand the excess cut material is minimum and the same shall be reused for theconstruction purposes.

The project will have a positive impact on the soils and soil quality as housing projectwill have landscaping and the soils will be protected due to conservation.

FIA- 9

During the occupation stage, compaction will not occur, and the compaction if any willbe restricted to road ROW. And the road ROW compaction cannot be said to be animpact of the operation stage as the pavement itself is a function of compacted baseand 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 negativeimpact on the receiving body if the same is not properly managed. Impacts due tosurface runoff include increased soil erosion and local flooding or water logging. Hencethe project will be designed with adequate storm water drains and cross drainagestructures. The housing activity will be provided with a Sewage treatment plant to treatthe domestic wastewater and necessary infrastructure will be provided for the safedisposal of domestic wastes to protect the water bodies.

2.8. What are the impacts of the proposal on the ground water? (Will there be tappingof ground water; give the details of ground water table, recharging capacity, andapprovals obtained 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. State ground waterboard is approached for necessary permission.

2.9. What precautions/measures are taken to prevent the run-off from constructionactivities polluting land & aquifers? (Give details of quantities and the measures takento avoid 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.

2.10. How is the storm water from within the site managed? (State the provisionsmade to avoid flooding of the area, details of the drainage facilitiesProvided along with a site layout indication contour levels)

Storm water drains will be provided all over the site to meet the expected increase inthe runoff during rainy seasons due to the impervious nature of the roads and otherpaved areas. It is proposed to maintain the levels as much as possible before lettingstorm water into side drains of main road.

Based on the catchment area, potential inflows and rainfall intensity determine thedrain size so as to minimize damage resulting from high intensity storms. Energydissipaters such as drop structures will be provided along the channel where runoffvelocities may become excessive. The overflow from the storm water drains atrainwater harvesting structures shall be provided with an overflow channel to drain intothe roadside plantation, which will act as a bioswale.

FIA- 10

Storm water drains: Conservation of water resource is most important aspect of theproject during construction and occupation phases. Storm water drainage planning,domestic water planning and sewerage transfer and sewage treatment planning arecritical aspects of construction and occupation stages of housing projects.

Storm water drains will be provided all over the site to meet the expected increase inthe runoff during rainy seasons due to the impervious nature of the paved areas. Thesite is uneven and it is proposed to maintain the levels as much as possible, hencestorm water outlets from the site are anticipated. The expected runoff is calculated forthe design of the storm water runoff and presented in following table.

2.12. Will the deployment of construction laborers particularly in the peak period leadto unsanitary conditions around the project site (Justify with proper explanation)

No, Temporary toilet facilities shall be provided and the same shall be connected toseptic tank followed by municipal sewer lines.

2.13 What on-site facilities are provided for the collection, treatment & safe disposalof sewage? (Give details of the quantities of wastewater generation, treatmentcapacities with technology & facilities for recycling and disposal)

PROCESS 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.The dried 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.

FIA- 12

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 forcedthe industries to look our for space saving, compact and efficient treatment options.This has led to the development attached growth processes where the bio mass isretained within the aeration tank obviating the need for recycle. These plants are notonly compact 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 highspecific biofilm surface area culminated in the most advanced technology of aerobicbiological fluidized bed treatment where the biofilm (biomass) grows on small carrierelements that move along with the water in the reactor. The movement is normallycaused by aeration 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 gravity0.92-0.96 the overall density could be expected to increase up to 9.5% when full ofbiomass such that they can fluidize using an aeration device. A biofilm develops onthe elements, which move along the effluent in the reactor. The movement withinthe reactor 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 inthe presence of oxygen available from the air that is used for fluidization.

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

FIA- 26

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 theapartments units. For climatic considerations, all these openings are placed nextto a balcony/sit out space which acts as a buffer by eliminating the directlighting and thereby avoiding heat ingress.

Use of Large fenestration 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 solarhot water systems for use in the building complex? Substantiate with details.Solar power shall be used for the water heating and lighting requirement.

9.6. Is shading effectively used to reduce cooling/heating loads? What principles havebeen used to maximize the shading of Walls on the East and the West and the Roof?How much energy saving has been effected?Yes, the apartment blocks are aligned east and west to maximize the shading.

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 usingCFC and HCFC free chillers? Provide specifications.

Building Materials The building materials chosen for the landed and apartment units are as per the

recommendations of the climatic standards. To achieve the maximum energy value, a balance between the availability of

building materials locally and skilled labourers is achieved. Burnt brickwork with fly ash for the walling and plastering reduces the thermal

penetration by 20-30%. The RCC roof is covered with Brickbat concrete and terracotta weather tiles,

which reduces the heat penetration by 18%.Colour of Facades

The colour choice for the buildings uses a maximum of white surface (nearly84%). This increases the solar reflectivity factor.

Emittance factor for white surfaces is around 90% compared to colouredsurface (20-60%)

16% of wall area uses earthen colours and this space has longer thermal storagein the walls. This creates a comfortable temperature at nights due to the thickerwalls designed.

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 oncreation of 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 tothe surrounding 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.
