Regulation Facilities At the Sewer Network As A Tool In Reducing the Effects of Heat Islands In Urban Areas

The research work is focused on finding extremes in climate changes which are related to rainfall-runoff process at catchment area. Location of our research is set to urban area of Slovak town Levice. During the inspections process we have made necessary calibration measurements to correct the identified defects in the project documentation. The main part of the research is evaluating the impact of rainwater to the sewerage system using block rain with selected periodicity, taking into account impact of proposed solutions for management of rainwater in the area. Evaluation of existing sewerage network was handled at periodicity levels p = 0,5; p = 0,05. The results show that climate change has high level of impact on the rainfall runoff. Even with a rain with periodicity of p = 0,5; i.e. rain that occurs once in per 2 years, we have identified specific points in the sewerage network unable to fulfill its function without extensive stress.
