| Summary: | 碩士 === 國立海洋大學 === 航運管理學系碩士在職專班 === 91 === Water is connected with everybody’s daily life. The quality of the drinking water is essential to all the people. Its key factors conclude water quality, water pressure and water quantity. The water- pipe distribution network, though broken at times, is usually not repaired in time, so it stained water quality and caused loss of the water quantity, which leads to the reduction of water pressure or cannot supply drinking water at all. Therefore, consumers tend to misunderstand and feel discontent for water supply system.
The research has two purposes. One is to analyze the leakage rate of every district, and the other is to calculate the reliability of every district for water supply system. Subject to the optimal economic principle of the water- pipe distribution network, water supply system can fully satisfy consumer’s demand. I hope that the research can offer managerial reference for every water supply system in shortening expenditure.
First, the means and contents of the research are to collect all details of the table for water supply network district, water pressure, water quantity and broken pipe leakage. They are all related to the water pipe number, which can provide the inquired details according to different conditions in Access. At the same time, I make use of SPSS or EXCEL to analyze the above mentioned details.
The main conclusions of the research are the following:
The leakage ratios and leakage quantity of Hou-tung, Chin-kua-shih… five districts etc I suggest that they must be inspected seriously. The reliability of every district for water supply system and the age of the pipe that the ratio of broken pipe over 1 and the age of the pipe over 30 years have 7 pieces. The above will lower the reliability of the water supply system, so I suggest that they must be replaced with priority.
