An integrated planning study for improvements of sewer system and treatment plant for a catchment in western Greater Copenhagen is presented. Alternative improvements of the total system are analysed using a mathematical model for the runoff in the sewer system taking into account the interdependencies between sewer system and treatment plant. The most cost-effective solution was identified through optimization of the hydraulic capacity of the treatment plant. The improvements of the selected solution consist of a realtime control (RTC) system for the combined sewer network, elimination of faulty connections to the separate sanitary sewer system, rehabilitation of untight sewers and extension of the treatment plant to meet stricter effluent criteria. The study was implemented as an interdisciplinary excercise between specialists in the fields of sewer modelling, sewer rehabilitation and waste water treatment.
