RATIONALIZATION OF SEWER PIPE SYSTEM ACCOMPANYING INCREASE IN ACCURACY OF QUANTITATIVE CONTROL FACILITY

Abstract

 The confluence improvement project has progressed, but the management accuracy of the quantitative control facility that is the base in the sewer management is low, and there are still issues in environmental load reduction and heavy rain measure effective in the pipe line system through utilization of stock and will be become problems in terms of maintenance management and project operation in the future. In this study, based on the hydraulic engineering theory and hydraulic experiment verification enabling diversion control with high accuracy, and the previous studies aimed to put them into practical use on extension of the knowledge of sewer standard books and practical cases, there is presented a method for planning a rational sewer pipe line system relating to the environment and safety in an urban area, such as a pollution load in a public water area and a heavy rain measure in a residential area still having issues even after the confluence improvement project. Promoting the efficiency of the sewer project requires reliable sewage flow rate management and the pipe line system through effective utilization of the stock, and the pipe line system utilizing the sewage flow rate control technique of this study contributes to the effective achievement of the project purpose with quantitative evaluation and cost reduction.
