Building Services Assignment

hello! I am one of the member of group H for the building services assignment. We have 5 members per group. In this website, we will share our knowledge which is related to building services. We are currently working for it at the moment, so we will try our very best to keep updating very soon. As I mentioned earlier, our group create this website not just for fun. It is actually for educational purpose. That’s all for me. Thank you.

PRINCIPLE AND DESIGN OF THE SOIL PIPE AND WASTE PIPE IN OUR BUILDING CASE

SOIL PIPE

  • A pipe which conveys soil water either alone or together with waste water or rainwater or both
  • Soil water is used water contaminated with solid waste or trade effluent
  • Soil fitment is those which are used to remove soil water and human excrete.
  • A soil pipe is a PVC or cast iron pipe used in plumbing installations to remove soiled contaminated water from toilets.
  • Generally, the diameter of soil pipe is larger and are designed specifically to remove solid waste from toilets
  • Soil pipe substantially larger than a regular waste water pipe. Average inside diameter around 10cm.

 

WASTE PIPE

  • A pipe which convey waste water alone or with rainwater. (no soil water and solid waste)
  • Waste water is used water not contaminated by soil water and trade affluent.
  • Waste water fitments is those which are used to remove waste water from washing and preparation of food.
  • Modern waste pipes are fitted with 2 screw caps. Both type of cap should be unscrewed carefully, exerting only minimum amount of pressureBS4DIFFERENCE BETWEEN SOIL PIPE AND WASTE PIPE
    WASTE PIPE DIFFERENCE SOIL PIPE
    Designed to only have liquids from kitchen, basins, drink fountains and tundishes. PLACE TO INSTALL Used for toilets, urinals, bidets and sluice sinks
    Waste Vents TYPE OF VENT Soil Vents

     Types of sanitary system

    There are a few types of sanitary system that used in a house or building for collecting or conveying a waste water. This sanitary system will collect all wasting water straight to the public sewer or domestic septic tank. As below, it is the types of sanitary system:

    a)one pipe systemBS5

    As image above, one pipe system is a system that collect all soil and waste water into one common pipes. All the branch ventilating pipes will connect to the one main ventilating pipe. This one pipe system is usually used by multi storey building. It is because, this pipe will replace the two-pipe system.

     

     

    b)two pipe systemBS6

     

  • Two pipe systems are a system that having a waste stank that received the discharge of fitments and conveyed to the ground level. This pipe is having to delivered it above of the water seal in a trapped gully that is connected to the drainage system. Meanwhile, for the soil stack, it will have received the discharge of soil appliances and will directly brought it to the underground drainage system. This system is can be seen in the image above.c)single stack systemBS7.pngThe single stack system is a very economical system in sanitary system. It is because it can be reducing the cost of soil and waste systems. This type also does not need a branch vent pipes.

     

    d)Modified single stack systemBS8

  •  Modified single stack system is a close grouping of the sanitary appliances. It is mean that the installation of the branch waste and soil pipes will not be need by the individual branch of ventilating pipes.e)The fully ventilated one pipe systemBS9
  • This type of sanitary system is a many sanitary appliance in ranges. It is because all the trap will have an anti-siphon or the vent pipe each. At this point, the vent stack will be connected to the discharge stack near to the bend to remove compressed air.

Method of Installation

As mention above, sanitary system is divided into three types which is One Pipe System, Two Pipe System and Single Stack System. Different types of system have their own method of installation. Based on our case building which is Block G11 at Kolej Rahman Putra UTM are using One Pipe System. Basically, One Pipe System are preferred for this kind of building where it is suitable to group all the soil and waste appliances and take all types of waters to a common sewer then to the place where water treatment or disposal located.

Since it is called One Pipe System, use only one pipe in collecting and draining discharge and usually all sanitary fittings are connected to one pipe only. So that means, all sanitary fitting being installed near to a main pipe that will easier to being connected to the branching pipe.

In this system, a separate vent pipe is provided and the traps of all water closets and basins are completely ventilated. The single stack vent pipes release compressed air that may have trapped at the base of waste and disposal water single stack pipe. The vent branching pipe connects the single stack vent pipe to the sanitary fitting.

Since this system is provided in multi-storeyed building, the lavatory blocks of various floors are so placed one over other. So that the waste water discharged from the different units can be carried through short branch drains to common soil and waste pipe.

DOMESTIC WATER SUPPLY

Domestic water supply also known as drinking water supply not only consist of drinking water but also include individual and domestic for instant and bubbling and cleaning.

It is to ensure domestic water safe to consumer, domestic water has to be treated before being supply.

Process of water treatment is

  1. Screening– removes objects such as rags, paper, plastics, and metals to prevent damage and clogging of downstream equipment, piping, and appurtenances. Some modern wastewater treatment plants use both coarse screens and fine screens.
  2. Coagulation– process carry out when a coagulant is added to water to destabilize suspensions
  3. Flocculation– After coagulation, the water flows into flocculation basins, where the flow of water is slowed and the floc has time to grow bigger.
  4. Sedimentation– the water flows into sedimentation basins, where the heavy floc particles sink to the bottom and are removed.
  5. Filtration– now the water travels through large filters made of sand, gravel, and anthracite. Filtration removes any remaining microscopic particles and microorganisms.
  6. Disinfection– the water is disinfected to protect it against bacteria. Chlorine is added to ensure that the treated water is free from pathogenic organism. Fluoride is also added support good dental health.
  7. Distribution– The clean water is then pumped into pipes.

Study Tour to Tanjung Piai

On 24th of september 2017 (Sunday), the two of our group went to Tanjung Piai for a study tour.

This is some photos of the facilities and services that we manage to captured in Tanjung Piai Johor also known as The Southern most Tip of Mainland Asia .

The environmental factors had affected the design, layout and availability of services there and the constraint in providing the services.

As we all know, it is Natural Park responsibility to maintain and support a wide variety of flora and fauna. From our trip investigation, Tanjung Piai are covered an area of over 926 hectares where almost 526 hectares of land is coastal mangrove while the rest of it inter-tidal mudflats. There are only a few building can be found around Tanjung Piai since it is surrounded by coastal mangrove forest so we can only recognize a few services. As we mentioned above, we only identified a few services which is water supply system, electrical and lighting system, sanitary system and safety instrument.  Since there are a few services available, we identified some of the environmental factors.

First and foremost, the unpredictable weather of Malaysia leading to uncertain temperature of that particular area. This can affects in providing services in certain area because not all services can adapt the unpredictable environment such as electrical and lighting system. Like Tanjung Piai in which did not provide any electrical and lighting system along the broadwalk due to hot temperature up to 32 celcius.

Other common environmental factors is air movement. Since Tanjung Piai are located near to the sea, the strong air movement will causes the sea level to rise rapidly. In this case, the installation of sanitary system are efficiently being installed and the material used are usually more water resistant.

Besides, the humidity is one of the environmental factors that had affected the availability of services there. As we all know, moisture is the form of humidity and precipitation can only slow the fire down and reduce its intensity. This means that safety instrument such as fire extinguisher should be installed for safety purpose even though humidity can helps in fire prevention.
