- A model for simulation of substance flows in urban sewer systems has been developed in the computer programme package MATLAB/Simulink. The model is called SEWSYS and it handles fluxes of substances within an urban catchment. SEWSYS keeps track of each substance; where it originates and where it finally ends up. Some of the substances included are water, phosphorus, nitrogen, heavy metals and PAH. SEWSYS consists of a stormwater module, sanitary wastewater module and a wastewater treatment plant with nitrogen reduction. Verifications have been carried out both for each component separately and for the model as a whole. The results show that the modelling approach is valid, but further enhancements should be made.

- A substance flow analysis of the stormwater system in Vasastaden in the city of Göteborg has been carried out using a substance flow model called SEWSYS. The model handles fluxes of substances within an urban catchment and keeps track of each substance; where it originates and where it finally ends up. The present sewer system has been studied and the status of sustainability evaluated. Different abatement measures to achieve a system with more sustainability have been modelled and evaluated. The measures include source control and end-of-pipe solutions. From this study it may be concluded that all the studied measures individually lead towards a very high reduction of the discharges of pollution to the water body, but the source control measures are recommended as a first choice since they by definition are sustainable.

Extension of storm water system at Ostra Torn, Lund

Konferensbidrag (refereegranskat)abstract
- When the Ostra Torn area of Lund, Sweden was further developed in the 1990s, storm water was connected to the old separate storm water system. This increases the risk of flooding near the connection points. In this paper, the function of the system is analyzed using Storm Water Management Model SWMM. Consequences of extreme storms are investigated: It is shown that it is not necessary to connect the new system to the old one, but instead the water could be redirected to flow through a greenway zone to a small creek. A downstream pond can be used to reduce peak flow. A hypothetical open canal system with small ponds is discussed.
