The Department of Irrigation and Drainage Malaysia (DID) released the Urban Stormwater Management Manual for Malaysia (MSMA) in 2000 as a guideline to address longterm national goals and priorities in ensuring that sustainable urban drainage systems are properly used. MSMA’s emphasis on control at source approaches may be divided into three categories: water quantity control, erosion and sediment control, and water quality control. As highlighted in the manual, a successful implementation of its principles and techniques though calls for involvement of various professionals including engineers, urban planners, environmental scientists, landscape architects and other professionals. Apart from civil engineers, not much known about the other professional’s involvement in the execution of MSMA. The development of comprehensive and adaptable techniques requires increased collaboration among a varied group of individuals engaged. However, progress toward more inclusive planning has been gradual, with technological and institutional lock-ins. Taking this into consideration, this paper discusses the findings of a survey carried out to assess the levels of understanding and involvement of urban planning professionals in the implementation of MSMA. The study was conducted using a questionnaire form approach in obtaining feedback from the respondents involved. Questionnaires designed to assess the levels of understanding and involvement of the urban planning professionals in MSMA were distributed to randomly selected urban planning professionals from government agencies and private firms. The responses were then tabulated and analysed using the Statistical Package for Social Sciences (SPSS) software. The findings of the study are based on the highest mean values for each category in order of priority: policy management and action (3.800), education and marketing (3.732), cost and maintenance (3.646), and technological design (3.817). Based on this order of priorities can indicate the main factors that are obstacles to the effectiveness of the implementation of MSMA.
Drainage systems play an important role in the development of managing surface runoff water. This is because without proper management of the drainage system, it can cause flooding in the area. Universiti Tun Hussein Onn Malaysia (UTHM) has suffered floods and caused significant losses. Therefore, the purpose of this article is to study the types of drainage systems available around the UTHM area. In this regard, semi-structured interviews were conducted with a number of respondents from the Development and Maintenance Office UTHM to study the problems of each existing drainage system around the area and to look at ways of improving the existing drainage system. The types of drainage systems available at UTHM have been identified as conventional drainage systems, Urban Stormwater Management Manual (MSMA), monsoon drainage, main drainage and land drainage. Problems such as drainage system, waste and clogged drainage also being identified. Among the improvements identified are replacing MSMA with open drainage. In conclusion, the study of drainage system implementation at UTHM can provide a clearer picture of the drainage system used around the study area.
A rainwater harvesting (RWH) system is a method of storing rainwater for future purposes. Universiti Tun Hussein Onn Malaysia (UTHM) has implemented this effort on some of the buildings in Main Campus, Parit Raja. However, this system has the weakness that caused the RWH system to stop from appropriately operated. Some of the RWH components are damaged because the design is not thought of thoroughly in the long term. Furthermore, the Main Campus is highly dependent on the treated water supply that caused a high amount of utility bills. Therefore, this study has highlighted the need to analyse the existing small scale RWH system in UTHM’s Main Campus, identify the suitable tank form for UTHM’s Main Campus’ small scale RWH system, and suggest a small scale RWH system’s design for outdoor purposes in Main Campus UTHM. This study has been carried out by using literature review, interview session and observation. The result shows that the small scale RWH system in UTHM Main Campus has a few strengths, weaknesses, opportunities, and threats. Cylindrical tank form is chosen to design the university’s small scale RWH system. A modular RWH system with the number of tanks installed based on rainwater catchment area is suggested and named E-SPAH, a concept of RWH system that emphasises efficiency and outdoor usage. Perhaps this study would help future researchers, universities, and contractors guide future small-scale rainwater harvesting systems for outdoor purposes in UTHM’s Main Campus.
Rapid growth in the construction industry has increased construction waste generation and caused serious impact on the environment. In Malaysia, most contractors are using the conventional method as the main method in the construction process. However, using conventional methods for construction work is not environmentally friendly because of the poor quality control at the construction site and the uncontrolled waste production. This has contributed to pollution problems in the environment in the form of air and water pollution, and construction waste. The aim of this study was to identify the type of construction waste and causes of waste generation from conventional methods with IBS. In addition, this study also suggests measures to minimize construction waste generation at the construction site. This study used quantitative methods of questionnaires as an instrument. A total of 200 questionnaires were distributed to the G7 contractors and developers in Johor to get feedback. The data obtained were analyzed using statistical methods and indices mean. From the results, it was found that most types of solid waste high in conventional construction are wood (3.85) but with the use of IBS, wood waste generation can be reduced (3.15). For the source of waste generation, it shows that the handling process is the main cause with the mean score (3.47) in IBS and the mean score (3.75) during construction is carried out for conventional methods. Therefore, IBS technology is the considered best option in order to minimize waste generation at the construction site.
