INTRODUCTION
Waste water from your appliances either flows to the main soil stack, and from there directly into the
underground drain, or it can flow into a trapped gully. Linked to the underground drain, this is fitted with a
metal or plastic grid to stop leaves and other debris from falling into the trap and blocking it. The drain
itself might run to the main sewer or, in rural areas, to a cess pit or septic tank buried in your garden.
IWK (Indah Water Konsortium) is mainly responsible for operating and maintaining the public sewage
treatment plants and network of underground sewage pipelines.

building to carry waste water to discharge
from wash basin, sinks, bathroom, etc.

11. RAINWATER AND DRAINAGE SYSTEM
9 | P a g e
INTRODUCTION
Rainwater drainage systems in buildings are designed to collect rainwater and then direct it to the public
network. It consists of a network of collectors, accessories and final discharge devices.
Rainwater from gutters should be drained separately - as heavy, prolonged downpour could overwhelm
the system. Downpipes can discharge over the grid of an open gully or be connected directly to an
underground drain pipe. From there, the water might run into a storm drain beneath the road or be piped
to a soak away somewhere in your garden, from where it gradually percolates back into the soil.
RULES, REGULATIONS AND BY-LAWS
1. LAW OF MALAYSIA ACT 133 – STREET, DRAINAGE AND BUILDING ACT OF 1974
(a) SECTION 56 – RAINWATER PIPES NOT TO BE USED AS SOIL PIPES
No pipe used for the carrying off of rainwater from any roof shall be used for the purpose of
carrying off the soil or drainage from any privy or water-closet or any sullage water.
(b) SECTION 57 – WATER PIPES, ETC NOT TO BE USED AS VENTILATION SHAFTS
No water pipe, stack pipe or down spout used for conveying surface water from any premises
shall be used or be permitted to serve or to act as a ventilating shaft to any drain or sewer.
(c) SECTION 61 – VENTILATING PIPES TO SEWERS
The local authority may erect or fix to any building such pipes as are necessary for the proper
ventilation of the drains and sewers belonging to it.
2. UNIFORM BUILDING BY-LAW (UBBL) CLAUSE 115 – ROOF COVERINGS AND DRAINAGE
All roofs of buildings shall be so constructed as to drain effectually to suitable and sufficient
channels, gutters, chutes or troughs which shall be provided in accordance with the requirements
of these By-Laws for receiving and conveying all water which may fall on and from the roof.
3. REASONING
- UPVC is used for vent pipes, waste pipes and soil pipes because it is more durable and more
cost-efficient than other materials.

13. CONCLUSION
16 | P a g e
As an individual assignment, we are required to use our Design Studio final project for this
assignment. The purpose of this project is to develop our knowledge of building services and its systems in
design and construction. We will demonstrate their understanding of building services by providing the
most appropriate systems for the building, which include electrical supply system, hot water and cold
water supply system, sewage and sanitary system, rainwater/ surface water drainage system. These
systems form part the plans for Building Plan Approval to Local Authorities. Hence, it is essential for an
architect to understand the systems well. The drawings must be reproduced into a computer aided
drawing with annotations which describe the planning and installation of all building services required. We
also need to include specific clauses from the Uniform Building By-Law (UBBL) for this assignment.
Through this assignment, I had mastered the ability of demonstrating a comprehensive
understanding of applicability of specific building services systems in response to practical considerations
which include electrical supply system, hot water and cold water supply system, sewage and sanitary
system, rainwater/ surface water drainage system. In addition, I had referenced the UBBL on where and
how to install these services that makes any building liveable today.
