Abstract
The life cycle energy analysis of social infrastructures including water pipeline system considering installation, maintenance control, operation, and dismantling is essential component. In this study, life cycle energy analysis was applied to establishment of pipe rehabilitation/ replacement strategies and energy consumption and hydraulic factors (nodal pressure) were used for result comparisons. The life cycle of water pipeline system was classified into three steps; 1) manufacturing and installation, 2) rehabilitation, maintenance, replacement and energy recovery form replacement, and 3) disposal. The energy consumption of water pipeline system was calculated at each step. In case of rehabilitation/replacement strategies two criterions were applied; 1) the time after the pipe was laid and 2) variance of pipe roughness coefficient. The developed method in this study was applied to a real water pipeline system of K-block in J-city, Korea and the results were analyzed. The developed method in this study can be applied to suggestion of basic method for specialization of water pipeline system maintenance technique considering energy consumption.
