A catchment model which describes the hydrological and hydrodynamic processes in the catchment to the Rya wastewater treatment plant in Göteborg, Sweden is presented. The model uses hydrological models (MouseNAM) of 20 subcatchments and a hydrodynamic model (MousePIPE) of the tunnel system to make flow and CSO predictions. The catchment model has been used to evaluate several different operating strategies of the plant's pumping station and will be implemented as an operating tool. Efforts are under way to establish hydraulic and mass transport models for the pumping station and primary settling so that a loading model for the activated sludge process can be defined.
