The subject of this master’s thesis is developing the conceptual solution for draining atmospheric water using software EPA SWMM. The terrain was analyzed and the sewerage was traced based on the obtained data. Based on climatic data, the hydraulic calculation of the model was preformed for rainfall whose recurrence period is two years and duration of 20 minutes and the results were analyzed. Then, the same model was performed for rainfall whose recurrence period is twenty years. At the end is given comparative view of the results of hydraulic analysis of the model for rainfalls of the same duration, but different recurrence period.
