The aim of the study is increasing the efficiency of surface runoff drainage systems` performance in order to prevent flooding of urban areas due to the climate change in conditions of increasing number and intensity of heavy rains taking into account the uneven distribution of rainfall over areas. Numerous studies on the uneven distribution of heavy rains over the area are heterogeneous and contradictory, which indicates insufficient knowledge of the issue. Thus, there arises a need for experimental and theoretical research to refine the coefficient K, which takes into account the unevenness of rainfall over the area. As a result of the study of the value of the correction factor K to the estimated costs in sewerage networks, recommendations are presented for updating the correction factor in SP 32.13330.2018 in accordance with the results of these studies.
