PROBLEM TO BE SOLVED: To increase a reliability of the measured flow rate of sewage discharged from a clean water use facility.SOLUTION: A sewage flow rate measurement system 60 measures a sewage flow rate of sewage discharged from a clean waste use facility JY1 to a public sewage flow path Gp arriving at a sewage purifying treatment facility GJP by a sewage flow rate measurement instrument 50 in a sewage discharge path 40 inside the facility, and stores a measured sewage flow rate in a data storage part 64 in a time series manner. When calculating a sewage total flow rate during a measurement period based on the sewage flow rate stored by the data storage part 64, in a poor measurement period in which a poor measurement occurs in the sewage flow rate measurement instrument 50, the sewage flow rate measurement system 60 performs conversion calculation of the sewage total flow rate expected to be measured by the sewage flow rate measurement instrument 50 in the poor measurement period by substituting the stored sewage flow rate on the period other than the poor measurement period by the data storage part 64.SELECTED DRAWING: Figure 1 |
