다국어 초록 (Multilingual Abstract)

This study is performed to evaluate the correlation of environmental factors for drinking water pipe deterioration using statistical analysis such as multiple regression, cluster analysis, discriminant analysis, and the adequacy and dependability of grouping factors used to deterioration prediction model. Results of this study are presented that high correlation related to pipe deterioration is showed not laying year of pipe but characteristic of surrounding area and analysis of chemical components.
Therefore, major influence factors of pipe deterioration for types of cast iron pipe are product quality of pipe, environmental factors using pipe deterioration evaluation model is classified to 4 types such as group related to pipe body and to hydraulic & water quality, and to characteristics of surrounding area, and to trouble & discontent of customer. And the very high adequacy of group classification is represented that the applied grouping items in this study are agree to previous studies.
