OPTIMAL CONTROL OF URBAN SEWER SYSTEMS–WHERE DO WE STAND TODAY?

Abstract

Combined sewer overflows (CSOs) are identified as one of the major environmental concerns at most of the cities to date. These untreated combined sewer overflows are directly discharged to the nearby natural water bodies and cause many environmental problems because of the increased pollution levels at natural water bodies. Constructing additional storage facilities, increasing conduit capacity, expanding pumping capacity and application of controlling strategies to utilize the existing storage in sewer network are the common mitigation solutions of CSOs. This research paper targets to present the state of art of control of combined sewer systems, including the author’s current research work in developing a holistic optimal control model for combined sewer systems.
