PART A
Overview
The following drainage system that have been chosen for installing in the medium rise
building would be the vented (modified) and single-stack system (a variation on the single-stack
system) (Harvey, Handley & Taylor, 2016). The system of drainage and plumbing is a variation
and mixing of both individual system of drainage system. The system is made with the
combination of both separate working system known as the modified vented drainage system and
the single-stack system. The mixed operational combination of these two system is what makes
this particular system work so well. The system helps in the drainage system and also the water
supply from the mains to the individual units of buildings (Ginige et al., 2017).
Venting in drainage system or water supply system is done my providing ventilation
system that helps in allowing the passage of air from the sanitary and supply pipe lines. As the
arrival of well pump in the house, the application of the well pump was to pump water out from
the ground (Urmee et al., 2018). After the modification of the drainage system, there were
installation of pipelines under the ground and under the houses of people. Thus, from saving the
pipeline form rapturing from peer pressure and stopping the backflow in the pipes, vent system
were introduced. There were installation of trap seal protection and the vent extensions that
would have at least one vent pipe extended to each buildings (Greenway, 2017).
The single-stack system used in the drainage system and plumbing provides a simple
solutions for plumbing system in medium raised buildings. The single stack system comes with a
stack aerators attached to it that have these three respective elements with them always – an stack
aerator in each floor, a pressure relief line at the very base of the stack and also venting in the

2PLUMBING SYSTEM OF MEDIUM SIZE BUILDING
roof (Hurlimann et al., 2018). The system have a offset chamber attached to the system, from
where the flow from upper floor of the building would enter the aerator attached in the stack and
the offset placed around the branch inlet placed horizontally.
The combination of this two system of plumbing makes a superior quality of plumbing
and drainage system that enables the water supply and the sewage system work efficiently.
Justification of selecting the following drainage system
First off all, there are four types of plumbing system that is used at Australia. Fully
vented system, modified system, the single stack system and finally the vented (modified) and
single-stack system (a variation on the single-stack system) (Armstrong et al., 2018).
From the following plumbing system, the following is most effective as it have the most
effective effect and benefits among all the other system used in Australia. The vent system
allows the passage of air through all the main pipelines, the branch and the sub-branch pipelines
that is attached to the main pipeline that carries the sewage to the treatment facilities. It also
helps in creating a suds pressure from the atmosphere pressure in the suds pressure zones in the
water supply pipelines (Code, 2015). Air is compressible and plumbing system could only
tolerate a small amount of change in the pressure as it already has a peer pressure from the flow
per area of both fresh and waste water in the different pipelines. It also allows the static head
pressure that is developed in the pipeline (McGrath et al., 2015)
The system also eliminates the excessive amount of air pressure or blockage that is
developed due to the pneumatic effect in the plumbing system. Due to the installation of aerator
in the stacking of the pipeline that is used by the single stack system, extra amount of air enters
the pipeline to from the lower level of the offset of the building as the blockage due to the

3PLUMBING SYSTEM OF MEDIUM SIZE BUILDING
pneumatic effect occurs there the most. As air tangentially inclined with the water in the
pipeline, the air flows with the same velocity as that of the water (Wilkinson, 2015). At points
where there is a hydraulic jump or opening to a wider or narrow vent or the water being
discharged to a stack, the air pressure in the pipe line is constricted, which creates the blockage.
Thus, the aerator used in the system helps them in coping up and saves the pipeline from
blockage (Reynolds et al., 2017).

The stack work related to this particular system is the combination of the modified
vented and the single-stack plumbing system (Schofield et al., 2017). The combined system
would be allowed to fit in the building with anti-siphon traps on each of the appliances with a
vent pipe that is connected to the main pipeline. As there is no need of branched vent pipes in the
single stack system, the combines system have the vent pipes attached to the main pipeline. The
system have a constrained branch pipes are attached to a trap crown of length 200 mm as in the
separately, the vented system the crown trap is of 300mm and in single stack system, the length
is 75 mm. However in the modified system which is the combination of the ventilated stack
system, the anti-siphon traps are closed together sufficiently for minimizing the loss of water and
also the limited in number have not to be vented individually. In this system, as shown in the
diagram, the branch pipes that carry the waste water and sewage could be ventilated. Unlike the
individual systems, the combined system of vented modified and the single stack system allows
pipes to be larger than the standard diameter to be fitted in the as waste carrying pipelines. It is
recommended that to prevent the loss of water for the trap seals, it is recommended to install
branch pipe of WC to be a minimum of 120mm bore and the angle at which the pipes should be
placed should be at least to be at 90.5 to 95 degree (Hambly et al., 2015).
In each floor, there are two apartments and there are four floors in the whole building.
There would be a total of 8 basins and 8 urinals in the whole building. For each basins, the waste
line attached to it should be a minimum of 50 mm in bore and angle at which it should be placed
should be 91 to 92.5 degrees. The minimum length of the basis pipe lines should be of 4.5 m and
25 mm bore vent pipe that spans and get attached to the main waste pipe at the point from the
two basin in the floor and farthest from the stack. The urinals must have a minimum of 50 mm in

6PLUMBING SYSTEM OF MEDIUM SIZE BUILDING
the pipe branches and the pipes should be short as much as possible. The gradient between the
pipes and the floor should be 90mm per 18m (Radcliffe, 2015).

The supply of cold water system in the medium rise building is done for fulfilling the
need of services like – cold water supply for domestic purpose, for air conditioner, using in the
sprinkles system and is the wash down facility. In the complex network of system in the pipeline,
the main tow components that helps in the supply of cold water in the building are the gravity
storage tank and the booster supply pump.
The pump helps in increasing the pressure of water in the main pipelines that distributes
water to the branch and sub branch lines in the water supply line. There is a reduction in pressure
in the pipes due to the pump and also there is also reduction in the neighboring properties. The
minimum drop in pressure is indicated by the Water Authority in Australia (Rogers et al., 2015).
The gravity storage tank in the building is the only stop where the water is stored that is
supplied from the mains of the supply chain of water.
In the building the supply of hot water is necessary and it is used for variety of purposes.
It is necessary for using hot water in domestic use. The supply of hot water is done mainly in the
bathrooms and kitchens and basins in an apartment. The requirements of heating the water while
supplying it to various branches in the building would be- boilers fired with the help of
electricity, gas or oil; heating circulation pumps, expansion tanks, venting and automatic electric
controls.
There could be construction of two type hot water supply lines namely the instantaneous
or non-storage system or the storage system. Instantaneous hot water systems heats water as it
passes through the heater. Since they do not store hot water they can be installed in smaller
spaces like under sinks (Rohmer et al., 2017). The heater continues to operate for as long as hot

8PLUMBING SYSTEM OF MEDIUM SIZE BUILDING
water is required. Instantaneous heaters normally operate directly from the domestic cold water
service at mains pressure. These systems can heat by either electricity or gas.
Storage systems heat the water and store in an insulated tank or cylinder for later use.

The lighting and the wiring plan is necessary for the placing and wiring, by execution of
electrical work that needs the skill to recite and take many different types of drawings and
diagrams. Sympathetic circuit ciphers and mechanisms is extra one of the basic structure hunks
wanted to develop an electrician. An electrician misunderstands a sketch or plan when wiring a

household, plans could be wrongly fitted or level misused in total. Meaningful how to right info
from an electrical picture or illustration and put on it to the actual creation is important for
electricians (Vieira et al., 2018).

Introduction
The following report is the illustration of variable for the hot water system of the
building. It is important for knowing the water reticulation system, for the supply of water in the
building before connecting the hot water system.
Discussion
The water distribution system in a medium sized building should be designed according
the codes that is used for creating the plumbing system at Australia. Codes such as Plumbing
Codes of Australia and other codes like AS 1718, AS 2280 and many more are used for the
creation of plumbing system and water distribution in a building at Australia. The distribution

10PLUMBING SYSTEM OF MEDIUM SIZE BUILDING
system connects both hot and cold water system. In the hot water system, a mixture of valves is
to be used for controlling the flow of hot water at the times when hit water is pumped form the
heat exchanger. The valves will be helping in separating the hot water from the flow of cold
water. Pipe sizes and types should be different as that of hot and cold water. Normal polyvinyl
chloride pipes cannot be used for the hit water supply as the heat would destroy the medium
build structure of the pipe. Thus, copper pipes or galvanized iron pipes are to be used for the
supply of hot water into the apartments (Nicholls et al., 2017). Another factor that would be
necessary for the different pipe size and types is due to the internal friction that is produced due
to the temperature differences in the hot and cold water. The sudden loss and increase in pressure
is also different for both hit and cold water. The demand of hot water in the winters is more than
that of cold water. Thus, the pipe sizes should be set accordingly to the demand of the water
supply in the building. Due to the increase or narrowing or shortening of the entry of hit water in
the pipes, hydraulic jumps occur in the pipes creating eddies in them and blocking the end of
exit. The blockage occurs due to the air pressure that moves tangentially with the water in the
pipes. Thus at narrow exists, the air accumulated cannot escapes producing blockage (Jeansonne,
2019). The aerator used in the hot water system in the building would help in creating a passage
of extra air in the pipeline that would open the blockage. The installation of the design of the
plumbing system should be also be dependent on the climatic factor. It should be kept in mind
that the pipes should be free from freezing points.
The different types of hot water system that could be installed in the building could be of
two types, a system of instantaneous storage or the non-storage system and the storage system.
The non-storage system does not have a hot water storage tank. The eater is
instantaneously heated and distributed to the various pipelines of hot water system.

11PLUMBING SYSTEM OF MEDIUM SIZE BUILDING
The storage system is of different type. It has a complete storage system that includes two
types of system, the circulating and the non-circulating type. The circulating system is the most
common system that is used in most of the building at Australia. In this system, the water is
heated with a heat exchanger or a boiler. One pipe enters the boiler or the chamber and one
leaves the chamber, keeping the hot water flow constant.
Conclusion
Thus the report could be conducted by providing the various kinds of hot water system
that could be installed in the medium rise building. The report provides a brief overview of the
various system of hot water system and how the system works.
PART D
Introduction
The following report is made for providing insight for the client to demonstrate the
different types of air conditioning system and its benefits in the medium rise building.
Discussion
The two types of air conditioning system that could be used in the building would be
namely the central air conditioning system and the individual cooling system.
The central air conditioning system is mainly designed for central cooling by the use of
heat pumps. The large compressor is the unit locator in the system that drives the process. An
indoor coil is filled with the refrigerant is used to cool the air and then the cycle is distributed via
the ducts created in different apartments. The cooling of the air done centrally, there is no
individual system at work (Sultan et al., 2015).

12PLUMBING SYSTEM OF MEDIUM SIZE BUILDING
The individual cooling system done by mainly with room air conditioners and
evaporative coolers. Thus in each of the apartment, the cooling system should be installed
individually.
This would increase the cost of the construction. Thus is wise to use the central cooling
system in the building. However, it is the decision of the client which one they would prefer.
Conclusion
Thus, the report could be concluded by providing a brief overview of the kinds of air
conditioning system that could be instated in the building.
