Note: One day of total storage is considered for the calculation of underground tank capacities, excluding firefighting storage and 0.67 day combined Storage is considered for
service floor and Overhead tank calculation.
Water Treatment and Receipt of Water:
Water from Municipal / tankers will be brought to firefighting tank and its overflow will be stored in the Raw water tank for the suitable treatment if required.
In case the fresh water deficit is supplemented with bore wells, we suggest having a resistivity test and hydro-geological survey to ensure good quality consistent water supply
throughout the year. Standby bore wells shall also be planned for the same.
The water received everyday shall be randomly checked for physical, chemical and microbial analysis to ensure that water quality is maintained.
There will be a separate pumping and distribution system for domestic & flushing water.
One set of Vertical inline pumps will be installed in the Pump room, which will transfer domestic water from underground tank to water tanks at service floor and other set of Vertical
Inline Pump will be at service floor, which will transfer domestic water from water tanks at service floor to overhead tanks at terrace of the building.
Domestic water supply for Top 3 floors will be supplied by means of Hydro-pneumatic (Terrace Booster) for adequate pressure at fixtures.
One set of Vertical pumping system will be installed in flushing tank near STP plant to, which will transfer flushing water from underground tank to water tanks at service floor and
other set of Vertical Inline Pump will be at service floor, which will transfer flushing water from water tanks at service floor to overhead tanks at terrace of the building.
Provision will be kept to supply domestic water to the overhead flushing water tank in case of emergency or malfunctioning of the STP.
Separate pumps are proposed for Wing C1 & C2.

    Sewerage Disposal
    The waste water and soil water will be collected from toilet blocks / kitchen to main drainage network.
    From toilets, wastewater will be collected into gully traps and through chamber it will be connected to main drainage line.
    From kitchens, the waste water generated will be passed through gully traps and through chamber it will be connected to main drainage line & finally to the STP.
    The main drainage line will discharge the soil and wastewater to sewage treatment plant for aerobic and / or anaerobic decomposition.
    Treated water will be used for flushing and landscape features like fountain and water body. Excess treated water will be collected in collection tank and finally disposed off into
    drain

Design Criteria
Maximum intensity of rainfall is considered as 100 mm/hr.
Average Co-efficient of Run-off is taken as 0.80.
Co-efficient of Run-off for paved area including internal road is taken as 0.80
Co-efficient of Run-off for green belt area is taken as 0.30
Co-efficient of Run-off for terrace area is taken as 0.90
A channel network will be provided at the ground level connected to rain water harvesting and over flow connected to external storm water drain.
Storm water sumps of suitable capacity will be provided in the ground in coordination with the structural consultant and architect.
A grating at the main entrance will be provided to prevent entry of outside rainwater to the premises.
Design Criteria
Option-1 : 100% percolation / infiltration of the rain water to raise the sub-soil water levels and no reuse.
Option-2 : Maximum possible storage of rain water falling in our premises and re-using the same for flushing and irrigation, surplus water to be used for percolation / infiltration.
100% percolation / infiltration of the rain water to raise the sub-soil water levels and no reuse.
Maximum possible storage of rain water falling in our premises and re-using the same for flushing and irrigation, surplus water to be used for percolation / infiltration.
The first option of 100% percolation / infiltration is possible only in the places where dry sub-soil aquifers are available so that the ground water table is recharged. This option
doesn’t give the immediate benefit of water to the society, but over a period of time maintains or increases the water table of the area.
Second option of storage of rain water and then re-using the same with suitable treatment is more advantageous in the present scenario where we are facing shortages of water. The
stored rain water can be re-used for air-conditioning, flushing and irrigation. In this case, the initial rains are allowed to drain away in the harvesting well or city drainage so as to
clean the storm water network and achieve clearer and better quality of rain water for usage.
Depending upon the space availability and as mentioned in EC, we are proposing rain water harvesting tank for WIng Also, there are 14 nos. of RWH Pits for whole plot
Refer following table for Rain water harvesting tank capacity calculation.
Being a high end project, the best quality fittings as approved by architect will be used.
Water saver taps, push type fittings for basins / sinks / urinals shall be used
Low volume dual flush cisterns shall be used to reduce water consumption.

FIRE FIGHTING
Introduction
The purpose of this report is to provide the client and the design team with an appreciation of the key fire safety provisions necessary within the WING at this stage in the
development’s design. This report will also subsequently be used for submission to the Chief Fire Officer (CFO) for his consideration when issuing a No Objection Certificate (NOC) for
the project.
The overall fire safety concepts for the WING described within this report will deal with the means of escape strategy within the WIng and the interaction with the physical fire safety
features proposed within the WING, such as Compartmentation and fire separation. In addition to these elements, the active fire safety features, such as sprinkler protection and
smoke control, will be introduced along with the WING’s proposed fire-fighting strategy.
The basic parameters for the fire safety design of RESIDENTIAL WING will be therefore be the following local fire safety codes;
   • National Building Code of India, Volume 1, Part IV Fire & Life Safety 2016
   • Practicing Engineers Architects and Town Planners Association (India) in Association with Fire Brigade Handbook on Fire Safety in High Rise and Special Type WINGs 1999
Fire safety systems within the WING will be designed to a selection of appropriate standards as indicated below:
Fire Alarm System                                                 NFPA 72, National Fire Alarm Code, 2002 Ed & CFO
Sprinkler Protection
The building will be protected throughout (inc. basement levels) by an approved and supervised automatic sprinkler system, to be designed and installed in accordance with IS
15105.
Underground water tank for Hydrant & Sprinkler System shall be provided. A Siamese connection will be provided near all Fire Department vehicle set down areas.
Rooms containing other types of electrical equipment should be sprinkler protected or provided with an alternative fire suppression system. Such alternative fire suppression
systems should be installed in accordance with the appropriate standard.
A private ring main, containing external fire hydrants, will be provided in the area immediately surrounding the WING for use by the Fire Service upon their attendance at an incident.
Internal Fire mains (Standpipe System)
Internal fire mains will be provided within the WING to assist in fire-fighting operations for both the above and below ground floors (ie. from the lowest to the highest storey within
the WING). The system will be provided as per NBC 2016 and any additional requirements as defined by the CFO.
The system will be provided with outlets within every escape stair enclosure (or protected lobby associated with each escape stair enclosure).
Fire Extinguishers
Portable fire extinguishers are to be provided throughout all areas of the WINGS in accordance to CFO NOC.
In our project ABC type & CO2 type extinguisher shall be used in Typical as well as Parking floors.
These systems has linear detection tubing which is installed throughout the panels and cableways. This tubing can not only quickly and accurately detect a fire but also suppress it
before it can damage adjacent components.
These systems do not need complex electronic detectors or panels and operate simply using pneumatics.
This alleviates the need for separate power supplies or battery backups and also makes the entire system fail safe with minimal moving parts. Electrical fire suppression systems use
the detection tubing which is installed throughout the enclosure and connected to the cylinder valve. The tubing is then charged with nitrogen and this pressure is utilized to hold
back the extinguishant in the cylinder.
Should a high temperature or fire occur then the pressurized tubing will burst and the extinguishant will be deployed directly from the burst hole onto the fire.
This effectively means the fire has formed the discharge nozzle so it is always exactly in the right location.
A switch is also added to the system and is held closed by the pressure. Should the tubing burst or the pressure be lost for any reason then the switch will open and this signal can be
used to isolate the power and raise an alarm.
The system will be designed to sound the alarm on the floors that require evacuation.
The philosophy to be adopted for fire-fighting within the WING will be such that sufficient internal provisions are included within the design in order that a ‘relatively’ safe
environment within the WING can be created, in an area located near the floor of fire origin, such that fire-fighting activities can all take place internally and that external fire-fighting
is not considered necessary.
Perimeter/External Access
For WIngs, require that an open space/courtyard be provided around the entire perimeter of the WING, a minimum of 8 m on either side, to allow sufficient Fire Service vehicle
access to the WING (this may however be Confirmed as per the requirement of CFO).
The necessity for vehicle access round all sides of the WING is based upon the presumption that the Fire Service expect to be able to fight a fire from outside the WING as well as
internally.
However, the fighting strategy for the Wing is that All fire-fighting will occur from within the WING (i.e. from the fire-fighting shaft using the wet rising mains etc.). This is the
preferred strategy as it is consistent for all fire locations within the WING. The largest fire appliance that the Fire Service have available to them has a maximum working height of
60m and therefore the vast proportion of the WING is always outside the reach of their tallest fire service vehicle. As such, fires above 60m (even if perimeter access was provided
around all sides as per the code) would have to be fought from within the WING. As a consequence, a more simplified approach will be adopted whereby good internal fire-fighting
facilities will be provided and fires will always be controlled from within the WING (irrespective of the height of the fire floor above ground level).
Where access to the site for the Fire Service is provided, the minimum width of any gate will be 6m and any entrance canopy/archway will be a minimum of 4.5m in height. The open
space at the entrance to the WING will be paved up to a minimum of 6m from the WING and the paving will be capable to supporting the weight of the a Fire Appliances up to 48
metric tons with a point load of 10kgs. Per cm2. The paved space will be free of obstructions and motor able.
Emergency Lighting
Emergency lighting will be provided throughout the WING in accordance with NBC. The lighting will be powered from a source independent on that for the WING’s normal lighting
capable of continuous operation for a minimum duration of 90 minutes.
The lighting will be positioned such that it clearly indicates all escape routes within the WING to allow the safe movement of people in an emergency as well as providing illumination
to all appropriate fire safety equipment. Emergency lighting will be sited to cover the following locations;
The horizontal luminance at floor level on the center line of an escape route will be at least 10 lux. For escape routes up to 2m in width, 50% of the route will be lit to a minimum of 5
lux.
The following areas / services to be minimally provided the passive fire protection system.
The cable ducts shall be sealed at every floor with noncombustible materials having the same fire resistances the fire eating of the duct.
The removable cover in the floors and the access panels shall be of the same strength of the fire rating as the floor and walls.
