To provide a sewerage system that can reduce required regulating reservoir capacity of a regulating reservoir.SOLUTION: Sewage flowed into a second diversion device 3 is controlled to be divided into the sewage having a maximum amount of sewage that can be discharged into a public water area, and the sewage having excess amount of sewage, with high accuracy. The sewage having the maximum amount of sewage passes through a first regulating tank 2A, a first orifice 24A, a second regulating tank 2B, a second orifice 24B, a third regulating tank 2C and a third orifice 24C in order and flows to a second discharge pipe 7b, and the sewage having the excess amount of sewage overflows from a first to a third overflow weirs 22A, 22B, 22C and flows to a regulating reservoir inflow pipe 9a.SELECTED DRAWING: Figure 5
【課題】調整池の必要調整池容量を低減できる下水道システムを提供する。【解決手段】第２の分水装置３に流入した下水は、第１の調整槽２Ａ、第１のオリフィス２４Ａ、第２の調整槽２Ｂ、第２のオリフィス２４Ｂ、第３の調整槽２Ｃ及び第３のオリフィス２４Ｃを順次通過して第２の放流管７ｂへと流れる公共用水域へ放流可能な最大の下水量である下水と、第１〜第３の越流堰２２Ａ，２２Ｂ，２２Ｃから越流して調整池用流入管９ａへと流れる下水量が超過下水量である下水とに高精度に分水制御される。【選択図】図５
