For combined sewer systems to reduce pollution loads to public waters, it is necessary to store the pollution load in a stormwater reservoir by using long-term predictions of the wastewater treatment plant's operation status based on inflow volume predictions. This paper describes the principle of a technology for predicting sewage inflow volume based on Topological Case-Based Modeling, and a sewage inflow prediction system based on this technology. It also introduces an operation guidance system using inflow volume predictions based on case-based modeling, and an application of this system in Yokohama, Japan, which succeeded in reducing pollution loads during wet weather.
