Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Risk Management Plan Developer –Display Vinimay Pvt. Ltd & 72 Others

RISK MANAGEMENT PLAN Risk Management Plan is an integral part of a modernized and sophisticated residential complex. No efforts should be spared in identifying the all possible risks and disasters, evaluating them, installing control measure and carrying out operations without any possibility of accidents. This plan details how emergency related to major accidents will be dealt with. In a residential complex, major identified Hazard pertains to fires in building. Thus, Emergency Preparedness Programme through proper design, operation and maintenance & inspection are essential to reduce the probability of occurrence and consequential effect of such eventualities. The overall objective of the Emergency Preparedness Plan is to make use of combine resources of the site and outside services to achieve the following: . Localize the emergency . Minimize effects on property and people . Effective rescue and medical treatment . Evacuation

PROPOSED FIRE PROTECTION SYSTEM WITHIN THE RESIDENTIAL COMPLEX Proposed residential complex is located abutting the Rajarhat Road at Rajarhat near Chinar Park. Surrounding area of the project site is developed with low to mid rise to high rise residential buildings and institutional complexes. Few industrial units are also located sporadically in the locality. Proposed complex is very well connected by roads for movement of fire tenders from the nearest fire station at Thakurpukur. Moreover, adequate fire fighting measures have been proposed in order to make the complex safer.

The first opportunity to achieve fire-safety in the proposed complex is through fire prevention, which involves separating potential heat sources from fuels. It is seen that major building fires are started by heat sources and ignitable materials that are brought into the buildings within the complex. This means the design of the building provides limited leverage on the building’s future fire experience.

In our design proposal, fire prevention is made more effective by careful observance of codes and standards in the design and installation of electrical and lighting systems, the water heating system and other built in equipment connected with cooking, refrigeration, air-conditioning or washing of clothes.

CONSTRUCTION . Whole construction of the proposed complex will be carried out as per the sanctioned building plan by concerned authority and recommendation of West Bengal Fire & Emergency Services Department. . The floor area exceeds 750 sq.m will be suitably compartmented by separation walls upto ceiling level having at least two hours fire resisting capacity. . The interior finish decoration of the building shall be made low flame spread materials conforming IS specifications.

OPEN SPACES . The width of the main internal road will be sufficiently wide as recommended by the fire department and sufficiently strong to withstand the load of fire tender. . Loop road surrounding all the buildings has been designed for smooth movement of fire tender. . Compulsory open spaces around the buildings will be kept free from any other usage. . Adequate passageway and clearances will be provided for fire fighting vehicles to enter the premises.

Page 1 of 5 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Risk Management Plan Developer –Display Vinimay Pvt. Ltd & 72 Others

STAIRCASES . Staircases of the building will be designed as enclosed types. Enclosure will be constructed in such a way that it has at least 4 hours fire resisting capacity. . Width of the staircase will be kept as per the recommendation of the concerned authority and all the staircases will be extended upto the roof level. . Fire and smoke doors at the entrances of all the staircases will be provided.

LIFTS Installation of lift will follow Section:- as per section 18 of part III & 6.18 & appendix A.15 of part IV of NBC. a) Minimum 1 lift capable of carrying minimum 8 persons weighing 545 kgs. shall be provided for every residential tower. b) Landing doors of lifts shall open to ventilated lobby & shall have a fire resistance of 1 hour. c) 1 lift shall be designed as a “Fire Lift” d) “Fireman Switch” shall be provided for each lift. e) Lifts shall not be used as means of evacuation. f) Collapsible gates shall not be provided for the lift. g) If more than 1 lifts are installed the partition wall should be of minimum 2 hours fire resistance.

REFUGE AREA . Section: As per section 8.12.3 on part IV of NBC, the refuge area shall be provided on the periphery of the floor & open to air atleast on one side protected with suitable railing. Thus, following NBC, Refuge area of at least15 sq.m will be provided on the external wall with cantilever projection at recommended floor levels of the individual buildings.

MEANS OF ESCAPE DESIGN . Accessway shall be provided for accessibility of site to fire fighting appliances. To permit fire fighting appliances to be deployed, the accessway shall have a minimum width of 6m throughout its entire length. Access openings shall be provided along the external walls of buildings fronting the accessway to provide access into the building for fire fighting and rescue operations. . Safe exit for the occupants in a building on fire requires a safe path of escape from the fire in the shortest possible time. This path, has been tried in our project to keep as short as possible for use in case of emergency.

LIFE SAFETY For ensuring the life safety of occupants from a fire, the followings have in addressed in general: . Provision of adequate No. of properly designed, unobstructed means of exit of adequate capacity which are available at all times; . Availability of alternative means of exit for use, if the already chosen one is inaccessible due to fire, heat, smoke and toxic gases; . Protection of the entire rescue path against fire, heat, smokes and toxic gases during the egress time based on occupant load, travel distance and exit capacity; . Adoption of compartmentation and other adequate passive fire protection measures to ensure the safe egress/evacuation of the occupants in case of fire; . Provision of adequate and reliable fire alarm system in the building to alert the occupants; . Provision of refuge areas where total evacuation of occupants is not contemplated; . Adequate illumination and marking of the means of egress; . Formulation organisation and practice of effective evacuation drill procedures.

Page 2 of 5 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Risk Management Plan Developer –Display Vinimay Pvt. Ltd & 72 Others

EXIT DESIGN The detail of the means of exit or egress or escape is a continuous path of travel from any point in the building to the open air outside at ground level. It consists of three constituents which are: (i) the exit access; (ii) the exit ; (iii) the exit discharge

The main requirements for the means of exit consisting of the three constituents as given above are: . All means of exit, including staircases, lift lobbies and corridors, shall be adequately ventilated; . Exits not properly ventilated can cause suffocation to people being evacuated because a large number of people would be present in such enclosed place with no natural ventilation till they get out of it and reach open air; . The building shall be provided with exits sufficient to permit safe escape of occupants, in case of fire or other emergency; . An exit may be a doorway, corridor, passageway(s) to an internal staircase, or external staircase, or to a verandah or terrace(s), which have access to the street, or to the roof of the building or a refuge area. Every exit, exit access or exit discharge shall be continuously maintained free of all obstructions or impediments to full use in the case of fire or other emergency. . All exits shall provide continuous means of egress to the exterior of a building or to an exterior open space leading to a street. . Exits shall be clearly visible and the route to reach such exits shall be clearly marked and signs posted to guide the occupants of the floor concerned. Signs shall be illuminated and wired to independent electrical circuits on an alternative source of supply. . The sizes and colour of the exit signs shall be in accordance with established international practice. . The floors of areas covered for the means of exits shall be illuminated to values more than 10 lux at floor level. . Fire doors with 2 hour fire resistance shall be provided at appropriate places along the escape route and particularly at the entrance to lift lobby and stairwell.

FIRE FIGHTING RESERVOIR Underground water reservoir as per recommended capacity by the Fire Services Department will be provided within the complex. The fire water reservoir shall have overflow arrangement with the domestic water reservoir in order to avoid the stagnation of water. The water reservoir will be kept full at all time. Moreover, the existing waterbody within the site may also act as the secondary fire fighting water reservoir, in emergency.

HYDRANT SYSTEM The building blocks shall be provided with Wet Riser or 150mm internal diameter pipe line with provision of landing valves at the Staircase Landings/ half landings at the rate of one such riser for 1000 sq.m of floor area. The system shall be so designed that shall be kept charged with water all the time under pressure.

FIRE PUMP Provision of the Fire Pump will be kept to supply water at the rate-designed pressure and discharge into the water based system, which shall be installed in the building. One such pump will be kept exclusively as Stand-by.

MISCLLENOUS GUIDELINES

Page 3 of 5 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Risk Management Plan Developer –Display Vinimay Pvt. Ltd & 72 Others

. Fire Notice for Fire Fighting and Evacuation from the building will be prepared and displayed at all the vulnerable places of the buildings . Floor numbers and directional sign of escape route will be displayed prominently. . Employees and Security Staff will be trained to be conversant with installed Fire Fighting Equipments of the building and their operation in emergency. . Mock Fire Practices and evacuation drill will be performed periodically and the residents of the complex will be encouraged to participate.

APPROACH FOR EMERGENCY PREPAREDNESS PLAN On site emergency: On-site emergency in this case can be defined as an accident involving only the people inside the premises, their rescue and fire fighting responsibilities. In case the effects are felt outside the campus, involving the surrounding residential, institutional as well as commercial establishments, the situation is called as an Off-site Emergency and this requires participation of emergency aid services. The identified major potential hazard is Fire. Apart from this an emergency situation may occur due to natural calamities.

The prime elements of approach for a comprehensive emergency preparedness plan have been identified as under:

1.Prevention As Project Proponent, M/s Madgul Developers Pvt. Ltd. has planned to take the responsibility of providing or maintaining a safe and secured complex. Studies have been conducted to identify and eliminate/minimize the potential hazards.

2. Preparedness From each floor of the building, volunteer occupants (one or two) will be selected as principle emergency guides. They together with the security staff and facility maintenance people should be trained to use fire-fighting accessories. A clause that will ensure such training shall be included in the fire-fighting equipment suppliers’ contract. These people will also be made aware of the evacuation procedures and emergency action plan. All necessary fire fighting equipment, fire hydrants, fire fighting reservoirs, etc., will be properly maintained and adequately replenished periodically.

3. Response In charge of the facility management will be responsible for managing all the emergencies. A reliable communication for him is a must as it plays a vital role during emergencies. Important phone numbers will be displayed prominently at his office/administration block. A plan showing escape route and position/location of fire hydrant will be made available to each residential flat with the complex. As per section 8.2.5 of part IV of NBC, the escape route should be marked with a sign board on the corridor & passage to guide evacuation. Normally, the escape route signboard will be written in luminous paint for easy identification. This is to guide every occupant of the building who is bound to panic in the event of accident. In addition to that the hydrant layout will also be as per the “Fire Protection Manual” of the Tariff Advisory Committee, General Insurance, 1998.

4. Responsibilities of Society of the Complex a) Appoint a Building Manager (Housing Administrator) responsible for fire safety. b) Establish emergency procedures to be followed at the time of an emergency.

ENVIRONMENTAL MANAGEMENT PLAN

The Environmental Management Plan can be divided in two stages-  During Construction Stages  During Operation Stages Therefore, a comprehensive Environmental Management Plan (EMP) consisting of necessary mitigative measures for protection and improvement of environmental status of proposed residential complex has been prepared for both construction and operation stages of the project.

1 MITIGATION AT CONSTRUCTION STAGE Construction work gives rise to a number of environmental problems, which need timely mitigation to maintain environmental quality. These impacts can be mitigated, neutralized and in some cases beneficial impacts can be affected if proper control measures are taken in time. As construction stage continues for relatively shorter period and different group of workers involved in different construction activities leave the place after a specific time span, environmental consequences of these activities are not significant.

2 MITIGATION AT OPERATIONAL STAGE During the operational stage, environmental pollution might occur due to the domestic as well as multipurpose activities in and around the project site. Due to those activities, the biotic and abiotic components of the surrounding environment might be affected. Therefore, proper mitigative measures and management techniques will be adopted as well as conservation procedures of natural resources and energy will be adopted. For example, solar lighting will be used partially for campus illumination; large window openings will be provided in the apartments for maximum utilization of natural lightings.

3 AIR QUALITY MANAGEMENT Regarding the management of air quality, it is seen that dust is the major pollutant due to construction activities as well as due to site maintenance and vehicular movement in and around the project site. Apart from the dust, a very small portion of CO and HC might be generated due to the vehicular movement and DG sets during the construction as well as the operation stage of the proposed residential complex.

3.1 Air Quality Management during Construction Phase  Stockpiles & haulage roads will be regularly sprayed with water to avoid dust.  Regular sweeping of access roads is required.  Wet Supressing Techniques (Watering) will be adopted during the construction activities.  All vehicles & construction equipments will be maintained to reduce emission.  All vehicles carrying building materials to the site will be covered to avoid spreading of dust.  Building materials like cement, sand, bricks etc. are to be unloaded within a covered storage space to avoid spreading of dust.

3.2 Air Quality Management during Operational Phase  Vehicular Movement inside the campus will be restricted.  Vehicles not having PUC certificates will be discouraged to enter the site.  Water will be sprinkled to suppress dust, while cleaning and sweeping the streets and pavements. Roads and pavement will be metallic or paved.  Open burning of litter and garbage will not be allowed.  DG sets will be have adequate stack height

Sufficient tree plantation will be done along the peripheries of the project site as well as inside the campus. Trees will act as an absorber of dust and CO generated inside as well as outside the campus. As an integral part of the landscape design, plantation of trees will enhance the aesthetic quality of the campus. Selection of plant species should be done on the basis of air pollution index of tree species along with the micrometeorological condition of the area.

4 WATER RESOURCE MANAGEMENT Regarding the management of water resources, it is seen that during the construction period, required water will be catered by supply water from ground water source. During the operational period, major part of the required water is expected to be obtained from same source. Balance water requirement will be fulfilled by collected rooftop rainwater and treated wastewater.

Page 1 of 5 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Annexure –10 Developer –Display Vinimay Pvt. Ltd & 72 Others

4.1 Water Resource Management during Construction Phase:  High-pressure hose shall be used for cleaning and dust suppression.  Construction equipment requiring minimum water for cooling and operation for optimum effectiveness will be chosen.  Ready mix concrete may be used to reduce on-site water consumption.  Effective water management will be adopted for optimum use of water during the construction stage. For example, water used for cleaning the bricks can easily be re-used for sprinkling the excavation and for land filling purposes.  Curing water will be sprayed on concrete structure; free flow water will not be used for curing.  Concrete structures will be covered with thick cloths/gunny bags and then water will be spread on them. This would avoid water rebound and will ensure sustain and complete curing.

4.2 Water Resource Management during Operational Phase:  The occupants and residents of the proposed complex will be encouraged for optimum utilization of water. Wastage of potable water will be avoided.  Use of efficient plumbing fixtures, sensors, auto valves, etc. will be adopted to reduce the water consumption and increase water efficiency.  During the monsoon period, as much rainwater as possible, will be collected and used for recharging the aquifer through Rooftop Rainwater Harvesting.

5 WASTE WATER QUALITY Regarding the management of water quality during the construction period of the proposed complex, the wastewater from the construction activities will be discharged into the municipal drain after necessary treatment. During the operational phase, generated sewage from the complex will be treated and reused for various secondary activities. The excess treated wastewater will be discharged into roadside drain.

5.1 Water Quality Management during Construction Phase  Construction waste and wastewater will be discharged into the municipal drain after removal of grit and debris in sediment trap. Wastewater will not be discharged into the open ground or neighbouring plot.  On site run-off containing dust and sediments will be controlled.  Leaching and stagnation of wastewater, which may contaminate groundwater quality in the locality, will be avoided.  For dust control purpose, over-watering will be avoided to control soil erosion.  While painting the building surfaces, as much paint as possible will be transferred from the roller, paint brushes and trays back into the paint container at the end of the day of job.  Wastewater from painting equipment cleanings and excess paints will be placed into larger drums and allowed the solids to settle.

5.2 Water Quality Management during Operational Phase  Potable water will be treated before use, if required.  During the monsoon period, as much rooftop rainwater as possible will be collected and properly treated before recharging the aquifer.  Regular cleaning & maintenance of all overhead & underground water reservoirs will be done.  Wastewater of sewerage line will be properly laid and the joints of two consecutive pipes will be properly sealed to avoid the leakage of wastewater or sewage, which may contaminate the groundwater quality of the locality.  The gradient of stormwater drain will be maintained properly. Drains will be covered with gratings. Water logging in open ground will be avoided.  Adequate number of service toilets will be constructed to avoid defecation into the open spaces.

6 LAND MANAGEMENT Regarding the management of land within the proposed complex, it may be observed that during the construction phase of the proposed complex, soil erosion due to the construction activities as well as surface runoff and soil contamination due to the construction waste and unorganized anthropogenic activities might take place. During the operational phase of the proposed complex, contamination of soil quality might occur due to improper disposal of household waste. To avoid those incidents, adequate measures during the construction and operational phase of the proposed complex will be undertaken.

Page 2 of 5 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Annexure –10 Developer –Display Vinimay Pvt. Ltd & 72 Others

6.1 Soil Management during Construction Stage  After the completion of the project, bare surfaces within the project site will be covered with vegetation.  While landscaping the open areas, gentle gradient in the land surfaces will be maintained as far as possible to avoid soil erosion.  Suitable stormwater drainage system for draining the surface run-off will be provided.  Excavated earth will be properly collected and stored within the project area. Excavated earth will be used for filling up the low-lying areas of the project site to the extent possible.  During excavation, the topsoil will be kept separate and used as topping material after land filling, dressing, grading or leveling work is complete.  Building materials will be stored on a platform within a covered area.  Designated waste collection areas will be chosen within the project site. Excess concrete will be dumped within this designated area.  Paint brushes, roller and excess paints will not be disposed off to bare ground, but will be collected into a container and will be disposed as solid waste after drying it up.  Vehicular access within the project site will be controlled.  Solid waste generated due to human activities will be collected properly and disposed off to the municipal authority’s solid waste collection system.

6.2 Solid Waste Management during Operational Stage  Solid wastes generated from different sources will be properly collected and disposed off to maintain hygienic situation within the complex.  No indiscriminate disposal of garbage will be allowed within the complex. A proper waste collection system will be implemented.  For residential apartments, it is recommended to go for House – to - House collection system (HTH). This will also prevent the solid waste to find their way into the roadside nullahs and drains. Thus the natural drainage of storm water is not interrupted.  For club & community area, garbage is to be primarily stored into a common storage bin of the respective floor and from there that will be collected and transported to the common waste bin of the site by the agency people.  Waste from yard and garden should be collected into the small handcarts by the sweeper and transported to the common waste bin.  Garbage collection is to be conducted during the early morning hours in a day.  Accumulation of garbage in the storage bin have to be avoided for more than 24 hours and collected garbage should be disposed off daily through municipality garbage disposal system.  The size of the waste storage bin should be adequate to accommodate at least two days solid waste. Storage bins will be non-corrosive with lids.  To avoid the dumping of garbage along the roads, parks, common areas, few number of solid waste storage bins have to be placed in strategic location.

7 NOISE MANAGEMENT During the construction period of the proposed complex, noise will primarily be generated from construction activities and vehicular movement within the project site. As all the construction activities will be carried on during the day time, the duration of the noise generation will also be during the day time. In the operational phase, there will not be any major source of noise pollution. However, to control the noise generation during the construction and operational phase, following measures will be adopted.

7.1 Noise Management During Construction Phase  The equipment used or the modes of operation can be changed to produce less noise. For instance, rotating or impacting machines can be used on anti-vibration mountings.  Internal combustion engines must be fitted with silencers.  Construction equipments are to be maintained properly and regularly for smooth functioning and less noise.  Vehicles not having proper silencer shall not be allowed to the project site.  Building materials like bricks, steel, coarse aggregate are to be unloaded on a sand bed and inside a covered storage area to produce less noise.  Construction activities will be done during the day hours.  Noise pollution attenuating green belt, especially along the boundaries of the project site is to be developed to reduce the impact of construction activities noise.  Temporary trenches will be dug along the external periphery of the building to prevent the spreading of ground vibration due to piling works.

Page 3 of 5 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Annexure –10 Developer –Display Vinimay Pvt. Ltd & 72 Others

7.2 Noise Management During Operational Phase  Adequate trees will be planted along the peripheral boundary walls, which will act as acoustic screen or vegetative barrier against the propagation of noise.  Generators in operation inside the campus should have silencers in the exhaust line. The generator rooms will have lining and acoustic insulation inside.  Vehicular movement inside the campus should be controlled. The speed of the car inside the campus will have limit and the drivers to be encouraged not to blow horn unnecessarily.

8 LANDSCAPE AND PLANTATION MANAGEMENT The project is completely vacant with no existing trees. However, sufficient trees will be planted according to the landscape plan. Thus, the landscaping and plantation programme within the project site will improve the aesthetic quality of the project site as well as of the surrounding environment. Following measures may be adopted to maintain ecological balance in and around the proposed development.

8.1 Landscape and Plantation Management During Construction Phase  Damage to roots of the existing trees will be prevented during trenching, placing backfill, driving or parking heavy equipment, dumping of trash, oil, paint and other material detrimental to plant growth. These activities will be restricted to the area outside the canopy of the tree.  Trees will not be used for support; their trunks will not be damaged.  Lighting of fires or carrying out heat or gas emitting construction activity within the ground covered by canopy of the tree will not be there.  Maintenance activities will be performed as needed to ensure that the vegetation remains healthy during construction period.

8.2 Landscape and Plantation Management During Operational Phase  Sufficient number of trees shall be planted inside the campus. The nature and type of plantation has been discussed earlier. Mostly native species will be selected for plantation.  Open spaces should be covered properly with grass. No bare open space shall be allowed to left as it may lead to soil erosion.  Proper care should be taken to maintain the trees, plants as well as ground cover.  Trees will not be used for support; their trunks will not be damaged.  Lighting of fires or carrying out heat or gas emitting activity within the ground covered by canopy of the tree will not be there.  Maintenance activities will be performed as needed to ensure that the vegetation remains healthy during operation period.

9 MANAGEMENT OF SOCIO-ECONOMIC ENVIRONMENT Proper administration and management is very much essential to maintain a good socio economic environment inside the proposed development. The development is residential in nature. Therefore, need of proper management is enhanced as the landuse around the proposed development is mixed in nature. Following measures may be adopted to maintain and improve the socio economic environment inside the campus.

9.1Socio-Economic Environment in Construction Phase  Adequate facility in terms of water supply, sanitation, fuel, electricity and other essential community services should be provided to the residing labourers at the project site.  Local labourers will be employed to the extent possible.

9.2 Socio Economic Environment in Operational Phase  Vehicular as well as pedestrian movement inside the campus will be restricted to the inhabitants of the complex and their service personnel only.  Illegal and unethical activities inside the campus are to be prohibited.  Proper safety and security measures regarding social aspects are to be adopted. In this regard, responsibilities may be laid upon a security agency to take care of the campus.  The inhabitants as well as the occupants should form a society for the overall maintenance and improvement of the proposed residential complex.

10 IMPLEMENTATION OF EMP AND MONITORING

10.1 Constitution of Environmental Management Division Various management techniques and measures have been suggested in the Environmental Management Plan (EMP) for the environmental protection and improvement of the proposed development. These needs are to be implemented as per the ‘Guidelines’ and monitored regularly as per the advice of WBPCB. It is suggested that the society or association of the proposed complex should have a full-fledged division known as Environmental Management Division (EMD) reporting to the top management. EMD should take necessary measures to look after the environmental management aspects of the proposed complex. The managers/officers of EMD should be given authority to look after their day-to-day activities for managing the environmental problems at the complex. The division should have sufficient funds to look after their day- to-day duties. The EMD should employ an Environmental Manager/Officer having adequate qualification & experience. Environmental Manager/Officer (Environment & Safety) should monitor the entire complex regularly and intimate the management about the current status of the environment and safety measures adopted. Management will review the reports of the officer and suggest certain remedial measures in consultation with the society of the residents of that complex for effective control of problems and pollution as well as maintain safety of the campus. Alternately, the society may engage a reputed agency in the field of environment, for undertaking above mentioned task of monitoring and implementation of environmental improvement measures in and around the complex.

1.0 INTRODUCTION To meet the increasing housing demand for the urban population, a number of multi-storied housing complexes are coming up in and around Kolkata Metropolitan Area. Also, the housing scenario of the Kolkata City itself has become saturated and beyond the affordability for the middle-income group people of the society. Side by side, people are getting tired out of rapidly changing living environment and increasing pollution in the Kolkata City. Therefore, due to above factors, an outward force is observed to become active for these people to settle their livelihood in the outskirts town of Kolkata. Hence, to meet this increasing demand of shelters, number of residential complexes are coming up in and around Kolkata City, where people can spend a better livelihood with a healthy built environment. Alongwith the residential sector, the commercial areas are also coming up in the region in order to cater the residents’ demand. Rajarhat and its surrounding areas are developing fast due to rapid growth of physical and social infrastructure. Display Vinimay Pvt. Ltd & 72 Others is also executing a residential complex at Mouza- Atghara, J.L. No. 10, R.S. No. 133, Dist.- 24 Paraganas (North) under Bidhannagar Municipal Corporation, West Bengal.

2.0 NEED FOR THE PROPOSAL Rajarhat area, in recent years, has got a major importance from location point of view. The transportation linkage of the area has been improved considerably due to the up gradation of Rajarhat Road. The existence of this Road, which connects Rajarhat with Kolkata etc., has enhanced the importance of the area as well as the land value. Moreover, the existence of Derozio College within closed proximity from the project site has increased its land value. Due to these factors, the rate of in-migration from the surrounding area as well as from outside has been increasing by leaps and bounds. Accordingly, the housing demand has gone high. To cater this housing requirement of the region and also to provide a better quality living environment for the growing urban population, the developer has planned to develop a multistoried housing complex at an affordable price. The main objectives of the housing complex are: i) To provide people not only with a beautiful abode with all possible amenities but also a better living ambience. ii) To provide all necessary infrastructure support and community facilities to the residents. iii) To ensure minimum detrimental effect on environment during the construction and operational stages and to mitigate the adverse impacts. iv) To help in Socio-Economic improvement of surrounding region.

The Project is already pre-certified as a Silver Rated Green Building by Indian Green Building Council (IGBC). Hence, the population calculation has been done following IGBC Green Home Norms.

6.0 MATERIAL REQUIREMENT FOR CONSTRUCTION Basic building materials for the construction of the proposed development are Cement, Sand, Stonechip, Brick and Steel as reinforcement. Though it is too early for estimation of consumption of building materials in this stage, but a sincere attempt has been made for preliminary assessment (whole project) for such consumption; which is presented below: Cement = 15700 tonne Sand = 43250 tonne Stonechip = 40100 tonne Brick = 1273770 pieces Steel = 4090 tonne

7.0 WATER REQUIREMENT, SOURCE OF SUPPLY, WASTEWATER TREATMENT & DISPOSAL Water Demand for the project (Construction Stage) = 24.0 kLD

Water Requirement during Operational Stage

(a) Domestic consumption of water = 398.0 kLD ……………..(i)

Type of User Per Capita water No. of Users Water Consumption Consumption (lpcd) (revised phase) (kLD) Residents 135 2884 389.34 Residents (floating) 15 288 4.32 Service Staff 45 100 4.50 Total 3272 398.16 say 398 kLD

Out of 398 kLD, 1/3 rd volume i.e. 133 kLD will be consumed for toilet flushing. This requirement will be met by supplying treated wastewater via dual plumbing system. Thus, net freshwater requirement for domestic purpose reduces to (398 – 133) kLD = 265 kLD.

(b) Water required for car cleaning = 13.0 kLD ……………………(ii) In the revised phase, proposed no. of car parks within the complex is 646. Assuming, all the cars to be washed everyday with requirement of 20 litres/car, total water consumption for car cleaning is 646 x 20 = 12.92 say 13.0 kLD.

(c) Water consumption for landscaping = 19.0 kLD ……………………(iii) Total Plot Area for Expansion Phase = 19,315.3 sq.m i.e. 1.93 Ha As per the SEAC guidelines, 20% of the project site should be reserved for tree plantation and other green surface. Thus area of project site for plantation is 1.93 x 0.20 = 0.386 ha. Assuming 700 trees/ Ha, required no. of trees within the site should be 0.386 x 700 = 270.4 say 270. Proposed no. of trees = 270 Page 5 of 8 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT

Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Project Report Developer –Display Vinimay Pvt. Ltd & 72 Others

Water requirement of one tree is 70 litres per day (based on the evapo- transpiration rate as 6mm on average, irrigation efficiency as 85% and plant factor as 0.4). Water consumption by the trees will be 270 x 70 litres = 18.90 say 19.0 kLD.

(d) Water reqd. for internal road and pavement cleaning = 7.0 kLD…………………….(iv) Total internal road and pavement area for revised Phase II is 4531.95sq.m. Considering water consumption as 150 litres/ 100 sq. m of roads and pavements, water requirement will be 6.8 kLD say 7.0 kLD.

(e) Water requirement for fire fighting Static water demand for fire- fighting purpose will be according to the fire department’s recommendation. In this case, an underground water reservoir will be provided for satisfying the requirement.

Total water consumption = 437 kLD (Water requirement for the fire- fighting is not considered as it is a static demand)

Sources of Water Supply The only source of water during and after the construction stages will be groundwater. Prior permission for abstraction of groundwater has been obtained from the concerned authority following all their guidelines.

WATER BALANCE DURING OPERATIONAL STAGE Water balance for the proposed complex is as follows:

Water requirement for domestic purposes = 398.0 kLD ( source: freshwater & treated wastewater) Water requirement for car cleaning = 13.0 kLD (source: rainwater) Water requirement for internal road cleaning = 7.0 kLD (source: treated wastewater) Water requirement for landscaping = 19.0 kLD (source: treated wastewater) Total Water Requirement per day = 437 kLD (This excludes firefighting requirement as that is static demand)

As 1/3 rd of this domestic water consumption will be used for toilet flushing, a volume of 133 kLD of the total domestic water requirement will be catered by treated wastewater.

Net Freshwater Requirement 265 kLD

Generated waste from domestic activities = 318.53 say 319 kLD (80% of domestic water consumption) Treated waste water available = 312.16 say 312 kLD (98% of the wastewater generated) Treated waste water to be used for internal road cleaning = 7.0 kLD Treated waste water to be used for landscaping = 19.0 kLD Rooftop rainwater to be used for car cleaning = 13.0 kLD

Sewage Treatment Plant will be constructed within the premises. A part of the treated waste water will be utilized for secondary activities like flushing, landscaping, internal road and pavement cleaning etc. Rest of the treated waste water will be discharged into the drain along the abutting road

SOURCES OF WATER SUPPLY Probable sources for water supply are from groundwater source, treated wastewater from S.T.P. and rooftop rainwater during monsoon. Water Consumption for Domestic Purposes: 398 kLD Page 6 of 8 Consultant – CENTRE FOR SUSTAINABLE DEVELOPMENT

Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Project Report Developer –Display Vinimay Pvt. Ltd & 72 Others

Generated wastewater : 319 kLD (80% of water consumption) Treated wastewater generated : 312 kLD (98% of wastewater) Treated wastewater to be reused : 159 kLD Treated wastewater to be discharged into road side drain: (312 - 159) kLD = 153 kLD.

The proposed sewage treatment plant will be of “Extended Aeration type system” with activated sludge process. It envisages collection of all the sewage water through a network of conduit with battery of inspection chambers and manholes and taken into a raw sewage water collection sump / equalization tank through a bar screen chamber. The equalization tank will have a retention capacity of approximately 4-6 hrs. Sewage from this tank will be constantly pumped into Aeration tank using effluent transfer pumps to achieve continuous re-circulation arrangement of the contents of the equalization tank. The aeration tank will have a detention time varying from 12 to 24 hours for continuous aeration. Aerated waste will be allowed to settle in a secondary settling tank and overflow will be let into semi treated effluent sump. The sludge will be partly fed back to aeration tank by pumping and the remaining sludge pass through sludge handling system consisting of automatic filter press, sludge thickener, dry cake handling equipment polyelectrolyte dosing for disposal. Dried cake will be removed and used as manure for plants. From semi treated water collection sump, water will be pumped through activated carbon filter, pressure sand filter and pumped and stored in a treated water tank used for landscaping and flushing after disinfection. From this tank, treated water will be used for landscaping and flushing purpose. The final quality of the treated waste water will meet the norms stipulated by the West Bengal Pollution Control Board.

8.0 SOLID WASTE DISPOSAL SYSTEM Volume of solid waste is 1.66 tonne/day. The break up of daily generated solid waste during the operational phase is given below:

Solid Waste Generation Calculation for revised expansion proposal (Phase II)

Type of User Per capita solid No. of Users Solid waste generation waste generation (persons) Residents 0.5 kg/cap/day 2884 1442.0 kg/day Residential Floating 0.1kg/cap/day 288 28.8 kg/day Service Staff 0.3 kg/cap/day 1000 30.0 kg/day Site Maintenance 0.05 kg/cap/day 3272 163.6 kg/day Total 1664.4 kg/day or 1.66 tonne/day

The collection and disposal method of generated solid waste is given below:  No indiscriminate disposal of garbage will be allowed within the complex. A proper waste collection system is to be implemented.  Waste will be segregated at source. To facilitate this, a multi-bin system will be provided for storing bio-degradable waste as food leftovers, vegetable and fruit peels, non-biodegradable waste such as metal scrap, rubber and recyclable wastes such as papers and plastics. These bins will be in different colours to facilitate the disposal. Organic part of the solid waste will be composted in a mechanical compost plant within site and the composted waste will be used as manure for horticulture.  For apartments, House to House garbage collection system will be adopted.  Waste from yard, garden and common space wil be collected into the small handcarts by the sweeper and transported to the common waste bin.  Garbage collection procedure is to be conducted during the early morning hours in a day.

Proposed Modification & Expansion of Residential Complex at Atghara, Rajarhat Road, Dist. – 24 PG (N) Project Report Developer –Display Vinimay Pvt. Ltd & 72 Others

 Accumulation of garbage in the storage bin will be avoided for more than 24 hours and collected garbage will be disposed off daily through municipal garbage disposal system.  Waste storage bin size will be adequate to accommodate at least two days solid waste. To avoid the dumping of garbage along the roads, parks, common areas, few number of solid waste storage bins have to be placed in strategic location.

9.0 POWER REQUIREMENT Power requirement for Phase – I (Existing Phase) is 1400 kW. For revised Phase – II demand load is assessed as 2270 kW. Thus, total expected power requirement for both the phases is (1400 + 2270) kW = 3670 kW. Power is supplied by WBSEDCL. D.G. Back up details are as follows; Phase – I (Existing Phase) = 2 X 250 kVA Phase – II (Revised Phase) = 3 X 250 kVA Total (for both the phases) = 5 X 250 kVA.

10.0 CONCEPTUAL PLANS The location plan, site plan and conceptual plan of the project is enclosed herewith.
