Implementation of the percolation facilities for rainwater runoff reduction

Abstract The article is aimed at finding out the behavior of the combined sewer network in the event of the occurrence of extreme precipitation events, which are associated with changes in the rainfall - runoff process in the urbanized area. Given the current situation of increased surface runoff in the urbanized area, it is necessary to extend the use of objects to reduce rainfall to the sewerage network. Part of the case-study was the design of percolation facilities in town Vráble, which are among the most used and most effective reduction measures. After designing the infiltration equipment and reducing the amount of rainwater discharged into the single sewerage network, the assessment of the sewerage network is satisfactory throughout the whole territory
