1.0 Electrical supply system 1.1 Electrical by law Electrical supply act 1997 [ACT 477] REGULATION [15] any conductor or apparatus that is exposed to weather, water, corrosion under heating or used in inflammable surroundings or in an explosive atmosphere shall be constructed or protected in such a manner as to prevent danger.

[16] fuse and circuit breaker are arranged in such a manner so as to break the current when it exceeds a given value for a sufficient time to prevent danger as well as to prevent danger of overheating.

Any electrical supply system shall not be overlooked as improper design can cause rapid, ineffective heartbeat or even death within minutes.

1.2 Components

Socket Mounted on wall, when a plug is inserted with the switch on, electricity will be transferred to the device from outlet.

Emergency light A battery-backed lighting device that switches on automatically when a building experiences a power outage.

The lights consist of one or more incandescent bulbs or one or more clusters of high-intensity ​light-emitting diodes (LED). ​Batteries are commonly made of lead-calcium, and can last for 10 years or more on continuous charge.

3

Recessed light Recessed lighting can achieve a wide range of lighting effects appropriate for a variety of purposes in diverse indoor and outdoor environments.

Ambient lighting, task lighting, accent lighting, and ​wall washes​ are all possible with recessed lighting fixtures using incandescent​, ​low voltage incandescent​, ​LED​, and/or compact fluorescent lamps.

Electric meter measure electric energy delivered to their customers for billing purposes. They are typically calibrated in billing units, the most common one being the kilowatt hour [kWh]. They are usually read once each billing period.

Distribution board divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

Smoke heat detectors fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element.

2.0 Cold water and hot water supply system 2.1 Pipe and service duct UBBL BY-LAW 84 Suitable measures should be taken to prevent penetration of dampness and moisture into the building.

BY-LAW 123 Adequate spaces to accommodate and access for pipes, stop cocks to allow repair, modification, extension, maintenance and access to ducts or enclosure.

To ease the maintenance and repair works, valves are placed before outlets to control the flow of water.

Sizes of pipe gradually decrease from the main pipe to the sub-distribution pipe to prevent unnecessary coatings and to avoid delay at outlets.

2.2 Components

Water tank - ​plastics​ (​polyethylene​) )​a container for storing water. ​Water​ tank parameters include the general design of the tank, and choice of construction materials, linings.

Stop cock a form of ball valve used to control the flow of a liquid or gas, ​used to grossly regulate the flow of tap water.​ ( at the junction of a water main and the branch leading to an individual service)

5

Copper pipe To channel hot water, as it can withstand high temperature.

UPVC pipe

(polyvinyl chloride) pipe, ​a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers.

3.0 Sewage and sanitary system 3.1 BY-LAW LAW OF MALAYSIA ACT 133 No pipe used for carrying off a rain water from any root shall be used for purpose of carrying off soil or drainage from any privy or water close or any slage water.

SECTION 57 No water pipe, stack pipe or downspout conveying surface water from any premises shall be used or be permitted to serve or act as a ventilating shaft to any drain and sewer.

WATER SERVICE INDUSTRY ACT 2005 NO 35 It shall be a duty of every facilities license to conduct refurbish, upgrade, maintain and repair its water supply and sewerage system and all other assets in relation to the system such that the facilities license is and continuously to be able to meet its obligation.

By separating pipe usage between rain water, soil and drainage, it ensures health quality of users as well as efficiency of channeling to the Indah Water Konsortium.

3.2 Components

Vent cowl providing air circulation through tanks where rainwater is piped directly into the top or side of the tank, rather than passing through a tank screen. Vent Cowls are also designed to fit the top of toilet vent pipes, to reduce pan syphoning.

7

Gully trap a basin in the ground which receives piped wastewater from your kitchen, bathroom and laundry before it is emptied into the sewer. The basin has a water seal to prevent foul odours of the sewer reaching the surface.

Floor trap prevent ingress of foul air, insects and vermin from the sewers into the building and resist the spread of disease. Traps are constructed, so that they retain a body of water which acts as a water seal.

Man hole top opening to an underground utility vault used to house an access point for making connections, inspection, valve adjustments or performing maintenance on underground and buried public utility.

4.0 Rainwater drainage system 4.1 BY-LAW BY-LAW 113 Prohibited of use of rainwater pipes for purpose of carrying soil and drainage from water closet, rainwater from any roof shall be used for the purpose of carrying off the soil and drainage from any of water closet or ant sullage water.

BY-LAW 115 Any roof of building shall be constructed as to drain effectively to suitable and sufficient channels, gutter, chutes or through should be provided accordance with the requirements of these by laws for receiving and conveying all water which may fall on and off from the roof.

It is the users’ responsibility to prevent any contaminants from flowing into storm drains and never pour anything into them as it is damaging to the environment and violating the government’s rules.

4.2 Components

Gutter beneath the edge of a roof for carrying off rainwater.

Rainwater downpipe When it rains, run-off flows down the roof, into the gutters and then is channelled down and away from the building’s foundation.

9

Drain sump Collect rainwater from rainwater downpipes, often covered with grill for safety purpose.
