| Operation of storm water systems in urbanized catchments, affected by increased size of drainaged area and its relative surface sealing, significant variability of rainfall events and increased usage of transport vehicles is connected to changes of sewage flow, pollutants concentrations and loads entering the sewage receiver. Thus, the application of numerical modeling to multi-variant analyses of storm water systems operation and its influence on the natural environment is reasonable and becomes a standard procedure nowadays. This paper presents the numerical modeling application to quantitative and qualitative analysis of storm-water sewer system in conditions of the selected urbanized area in the town of population reaching 40 000. The US EPA’s (United States Environmental Protection Agency) software SWMM 5 was applied to our studies. Three different rainfall events of various time and intensity were applied to our research. The presented analysis was based on sewage flow velocity, wastewater table height in the pipelines and the load of pollutants leaving the sewerage system. The sewage flooding from several chambers was observed. Our studies reveals also the fact that the studied system is partially undersized and the observed concentration of TSS entering the receiver exceeds the maximum value allowable by the local standards. According to the lacking model calibration, our observations should be treated as the preliminary studies. |
