equivalent to 80 % of estimated daily water demand .
Sewage treatment consist of primary, biological &
tertiary treatment.
Effluent from STP, as per outlet parameters is used for
landscape irrigation & HVAC make up water supply.
STP is compact, odor free, consuming minimum
electric power,
simple in O & M.
TREATED WATER STORAGE & PUMPING
Treated water after tertiary treatment is stored on a
recycle water tank.
Treated water is pumped for various purposes from
this tank as follows:
I.Submersible pumps including standby for
landscape irrigation.
RAIN WATER DISPOSAL & RAIN WATER
HARVESTING
•Rain water entering into the basements through ramps
etc is facilitated by Provision of channel drain with pre
cast RCC / CI gratings discharging in to Sumps at
suitable locations.
•Rain water from sumps are then be pumped to
Nearest storm drain at G.L. by providing submersible
dewatering pumps
•Rainwater from terraces shall be collected through
PVC rain water down take pipes At planned locations
which are connected to catch basins. However rain
water from open courtyards are collected through a
network of RCC & Collection chambers with desired
slopes, For rain water harvesting.

5. SECURITY SYSTEM
As per CPTED (CRIME PREVENTION THROUGH
ENVIRONMENTAL DESIGN)
The crime opportunity gets limited with the proper design
and effective use of built environment. Crime free
qualitative life can be achieved by giving a thought
towards the security during the design process itself. The
technology and systems becomes more effective if not
readily apparent to public eyes.
Following are few of the concepts used to develop
effective building security programs:
•Provision of CCTV for security system in Trilium Mall at
Amritsar has been proposed.
•77 no's CCTV (12 box type and 65 dome type) cameras
have been proposed which will be monitored from room
provided in Basement floor,
• For recording 5 hard discs of 500 GB capacity has been
provided.
For monitoring 2 no's 42” plasma TV have been proposed.
•Effective lighting along the pathways, entrances, exits,
parking areas, stairs etc. has been proposed.
•Point of entry to the building is clearly identifiable which
will be watched by guards, passing traffic.
•Bright lighting along the security areas has been avoided
that hinders the view for the potential observers.
•Voice evacuation system (Audio system) has been
proposed.
•Attendants or cameras and sound monitors used.
Indicating the presence with signs.
CCTV CAMERA ON BASEMENT PARKING ENTRY
AIR CONDITIONING
Air conditioning is a very important aspect of
services. It is needed to provide year round
comfort with help of economical and efficient air-
conditioning system. The mechanical ventilation
system is also provided for parking Electrical
Sub-station, DG room, AC plant room etc.AC
plant has been located in the basement.
Basement contain a number of Ventilation
rooms, fresh air and exhaust air shafts etc.
The total estimated load of building is 1125 TR at
peak. Considering a diversity of 80% the plant
has been designed for 900TR working.
AIR HANDLING UNIT (A.H.U)
AHU(Air Handling Unit)
The housing/casing of the air handling unit shall
be double skin construction. The framework shall
be of extruded aluminum hollow sections. All the
frame shall be assembled using pressure die
cast aluminum joints to make a sturdy, strong &
self supporting frame work for various sections.
GENERAL FEATURES
The air handling units is manufactured in a
company certified in accordance with the ISO
9001
v2000 standard.
Supplied AHU is of the “Wesper” brand and of
“Premi@ir” type.
The unit construction is complying with the requirements
of the European standard EN 1886:
Casing strength: Class 2A
Casing air leakage: Class B/B
Filter air leakage: Class F9
Thermal Conductivity: Class T2
Thermal Bridge: Class TB2
The AHU’s in this mall are selected with the aid of an
EUROVENT certified software programme that delivers
AutoCAD compatible execution plans, scaled to the
AHU’s size, fan performance curves with operating
points and a printout of the air humidity diagram with the
requested change points.
The AHU’s are delivered with continuous base frame.
This base frame comprises the
required openings of sling hooks / handling
as well as openings for attaching rubber
pads.
FALSE CEILING
False ceiling is done to give a neat and clean finish to the
ceiling. The void space left between the slab and false ceiling
gives an obstruction free area for the layout of services. This
area is accessed via services like fire protection systems (
sprinklers, smoke detectors,heat detectors) lighting
system,AC ducts,cables etc.

6. ELECTRIC SUPPLY
The electrical sub-stations in the basement where two
transformers of 2000KVA each have been placed with a
wall separating them to avoid fire hazards.For
uninterrupted power supply eight DG sets. 500 KVA
each. Hence a backup of 4000 KVA is supplied.
The overall electricity requirement of the Trilium is 3638
KW but the electricity supply from the authorities is of
4000 KVA, hence the requirement is met with the help
of generators I.e DG sets etc.

DIESEL GENERATOR SET
Capacity of DG sets is 500 KVA 8 no.s
o The scope of work comprises of designing
manufacturing, testing at work, packing, insurance,
storage at site, installation, testing and commissioning
of diesel generator set including its batteries, battery
charger, and AMF panels.
