Confluence improvement projects in sewage systems have seen some progress, but the management accuracy of the quantitative control facility, which is the basis of sewer management has remained low. Moreover, there are still issues in environmental load reduction and effective heavy rain measure in the pipeline system through utilization of stock, which may become problems in the future in terms of maintenance management and project operation. This study is based on the hydraulic engineering theory and hydraulic experiment verification that enables diversion control with high accuracy, and the previous studies designed to extend the information from sewer standard books and related cases into practical use. It presents a method for planning a rational sewer pipeline system considering the environment and safety in an urban area, including the pollution load in a public water area and heavy rain measure in a residential area that still experiences issues even after the confluence improvement project. Promoting the efficiency of the sewer project requires reliable sewage flow rate management and the effective utilization of stock in the pipeline system. The pipeline system utilizing the sewage flow rate control technique in this study is seen to contribute to the effective achievement of the project objective through quantitative evaluation and cost reduction.
