Availability of CSO Control and Flood Control of Real-Time Control System in Urban Pumping Station
Abstract:In 2004, Bureau of Tokyo Sewerage has installed real-time control system (RTC system) to Umeda pumping station. RTC system in Umeda pumping station differs from the one in Shinozaki pumping station, which installed RTC system first of all plants of Bureau of Tokyo Sewerage in that its equipments are not only CSO control but also flood control by operating pumps according to the inflow increase. The purpose of this thesis is to evaluate the RTC system in Umeda pumping station by the field test.
The field test, which was done from 2005 to 2006, showed that the RTC system reduced 19.2 % of discharged stormwater, 27.3 % of BOD, 27.6 % of COD, and 24.3 % of SS compared to before. And RTC system operates pumps precisely to match the downpour, therefore there are no disasters such as inundation around the basin of Umeda pumping station. As shown above, we confirmed the availability of RTC system.
