Set Up

The recently developed water quality simulation model FGSM of the German Association for Water Pollution Control (ATV) has been set up to simulate major water quality parameters of a small urban stream. After collecting the necessary input data the model was calibrated for dry weather conditions. Based on the calibrated model typical combined sewage overflow events were simulated. The model was able to simulate dry weather conditions well. For the simulation of combined sewage overflow events a typical event was simulated. The model was able to simulate high peak flows almost without damping. The biological oxygen demand was shown to sharply increase up to 20 mg/l, while the oxygen concentration decreased to less than 5 mg/l. The simulation showed that dissolved oxygen levels stayed during the simulated event above 4 mg/l. The FGSM appears to be a valuable tool for assessing not only the chronic, but also the acute effects of combined sewage overflow events.

Combined Sewage Overflow

In a small river catchment, microbiological quality of different sewage treatment plants under regular conditions and in case of heavy rainfall, when combined sewage overflow basins (CSOs) are activated, was examined regarding microbial indicators and pathogens. In the watercourse, no self-cleaning effects could be observed. Small compact treatment plants discharge treated wastewater with a poor microbiological quality compared to river water quality and the quality of treated wastewater of larger plants. During storm water events, concentrations of microorganisms downstream of sewer overflows were approximately two logs higher than during dry weather conditions. Concentrations of parasites decreased slowly during the overflow, in parallel to filterable matter and particle-bound substances. The annual load of microorganisms originating from CSOs significantly exceeds the load from treated effluent of the sewage plants. Thus, an improved hygienic quality of the water course could be achieved by preventing overflows and by enhancing sewage treatment plants.
