碩士 / 朝陽科技大學 / 營建工程系碩士班 / 100 / Recently, the installation of sewer system in the major metropolitan areas throughout Taiwan has become of the most important government projects, in which the increase of household connection percentage is the major target by the related government administration. The household connection percentage has been increased from 11.5% to 22.1% as a result of overall efforts by all involved sectors in Taiwan from year 2003 to 2008, while during the same time period the percent of processed household sewer water increased from 22.8% to 32.0%. Based on the knowledge and techniques obtained from past completed sewer projects in Taipei and cities in Japan, 3 installation models (A, B, and C) were identified and examined for the current and future sewer projects in Taiwan.
The study was conducted to investigate the selection and feasibility of using one of the selected 3 installation models for the sewer system installation in the Taichung metropolitan area in central Taiwan. Results of the study include comparison and difference between the 3 installation models during installation operation to provide adequate information for selection of suitable model best for particular site and building conditions. In addition, improvement tactics for all perspective models were obtained as results of case data studies regarding strength, weakness, opportunity, and threat (SWOT) of each installation models with respective to project factors of material and design of sewer line, and environmental conditions. However, lack of data and study regarding the in-direct cost and life span of the sewer line materials have imposed significant uncertainty and negative impacts on timing and successful completion of the sewer line installation projects in the study area.
A series of laboratory tests regarding sewer discharge velocity were also conducted along with analysis of installation cost, function, maintenance, and life span of each model for better understanding and selection of proper installation model. Results of the study can be useful for future similar sewer installation in other metropolitan areas in Taiwan.
