This study introduced two control systems that were a storm sewage overflow chamber control system and a stormwater and combined sewer storage tank control system. The former system controlled to collect less or to block off a discharge of storm sewage of low-concentration after collecting a discharge of storm sewage of high-concentration first. The latter system controlled the storage tank to store combined sewer overflows and first flush of separated storm sewage sewer by dividing high and low concentrations. The applications of these systems to an actual field have the advantages of the efficient utilization of interceptor pipe by maximizing a pollution loading amount of the inflow and the improvement of water quality and the surrounding environment by minimizing a pollution loading amount of the outflow. During the rainfall, these systems are able to improve the treatment efficiency of sewage treatment plants by flowing a discharge of storm sewage of high concentration selectively. Furthermore, these systems can guarantee water resources and prevent a contamination of our water supply with the improvement of water quality due to collecting and treating first flush of separated storm sewage sewer according to each concentration level.
