| Summary: | The development of sustainable wastewater infrastructures is very critical at the initiating design stage in order to guarantee a long term achievement of services. Thus, sustainable strategic planning and engineering process including site planning is an important factor. Malaysia has undergone various experience and challenges in managing their sewerage management system. Most of the sewage system was developed by the developers to serve their own scheme development. This resulted in varies degree of design, sizes and performance quality. Moreover, some of the systems are inherently defective in design. The current sewerage system in Malaysia consist of a combination of centralize system and decentralize system. The choice between centralize or decentralize sewerage system will need to take consideration the existing situation and also the needs which differ based on the location. There is no universal applicable methodology can provide the definite solution is selection of centralized or decentralize sewage system. The aim of this study is to identify the factor influence for the selection of Sewage Treatment Plant (STP) construction between centralize and decentralize system. Thus, this paper review the current practice of sewerage system in Malaysia and the factors influencing the selection of sewage treatment plant construction with the centralize over decentralize system. The methodology of this study presumed with thorough literature to understand the scenario of the existing sewage treatment plant, gathering information and data collection from the questionnaire survey, and followed data analysis using frequency analysis and average index formula. The results from this study recommend the most influence factor and the implication to the selection of the sewage treatment plant construction. Based on the result, the important factors influencing this decision are topographical, size of catchment and location, land availability, buffer zone requirement, total capital and recurrent cost, requirement for future expansion and environmental impact as well. |
