Order to minimize the effect of construction on the public , apart from the active replacement of old pipes , we have also introduced a new method for continuous water supply to be used in particular places , so as to reduce the scope and frequency of water suspension . even though the cost is higher , it can effectively prevent water pollution and reduce water loss during the construction 了降低施工对民众造成的影响,本处除积极汰换老旧管线外,也引进新的不断水工法,用在特定场合以缩减停水范围和次数,虽然成本较高,却可有效防止水质污染减少施工时所流失的水量。
