Abstract

An integrated system in Flanders consisting of a sewer, a wastewater treatment plant and a river component is selected for a modelling project. The purpose of the study is to assess the impact of combined sewer overflows on the receiving water and to investigate on the effects of different operating scenarios within the sewer system. Commercial mathematical models are used, i.e. both the sewer network and the wastewater treatment plant are modelled with Kosim, while Isis is used to represent the river system. The paper will mainly focus on the calibration process of the integrated model. Hydraulic measurements were carried out in the sewer system over a period of 6 weeks and overflow volumes and loads, together with river pollutant concentrati
