| Summary: | 碩士 === 朝陽科技大學 === 營建工程系碩士班 === 96 === In recent years, the construction and completion rate of the sewerage system in metropolitan areas have been selected as one of the most crucial environment indices for evaluating developed advanced countries where sewerage system is an essential public facility for the civilians. Due to tremendous amount of budget required, the “Act of Promoting Private Sector Participation in Public Projects” was first implemented by the government as part of the project “Challenge of 2008 Key national Development Plans” to introduce the role of private sector in order to expedite the construction process and completion rate of the sewerage systems throughout the Taiwan region. It is generally believed that the highest risk from applying the ACT is that the sewerage constructions for the major metropolitan areas in Taiwan are not financially self-sustainable and the investment and/or subsidization by the government are critical for the feasibility and success of such constructions.
The study was conducted on the basis of the “Modified Construction Plans for Sewerage Systems, Phase III” in Taiwan to analyze the feasibility of the sewerage constructions including the risk and financial analysis when the aforementioned Act is applied during the plan/design process. Taichung City in central Taiwan was selected in the study as the model case study for the analysis and the results revealed that:
(1). The related law/regulation should be reviewed and revised to avoid delay of the contracts in finance and construction due to the lack of government investment/subsidization or disapproval by the legislation of the local governments.
(2). The difference in user’s rate should be avoid for counties in Taiwan.
(3). The average project cost including construction and operation for the sewerage system is about NT $12 million/hectare in the Taichung City area.
(4). The most critical factors in affecting the investment return rate for the sewerage system are rate reduction ratio, construction cost, and operation cost, with a variation rate of +_ 20% is used in the analysis.
