Abstract Frequent floods and deterioration of drained water quality are the main problems in rapidly developing urban zones, mostly because urbanization reduces the areas with natural ground that can absorb stormwater and therefore prevent floods and pollution. In order to have a solution which can solve these problems and which could be acceptable for the nature and people, decentralized drainage systems were developed and applied. The primary goal of decentralized systems is to improve infiltration, evapotranspiration, and reuse of stormwater. This study presents the analysis of three variant solutions for the management of atmospheric stormwater. Analyzed solutions are based on the classical sewage system and on low impact development (LID) techniques applied in urban areas (Kucevo, Serbia). The main aim of this analysis was to define the pilot procedure to reduce pollutants and quantity of drained atmospheric water and using stormwater management, because the Pek River is one of the Danube tributaries. After the analysis of all solutions, the third variant solution based only on the LID techniques (vegetative swales, infiltration trenches, rain barrels, and bio-retention cells) gave the best results. According to simulation results, the proposed techniques in the third solution totally remove all pollutants from stormwater and stormwater surplus. Keywords Stormwater . Sewage system .

Introduction The assessment of the United Nations is that approximately half of the Earth’s population lives in urban zones and the future projections show that urban population will increase to over 65% of total population by 2050 (United Nations, Department of Economic and Social Affairs, Population Division 2014). This exponential growth of population in urban areas resulted in the poor quality of constructed infrastructure, which caused urban flooding and degradation of the

drainage stormwater quality. The first flush which occurs in the early part of storms presents a special problem for the quality of drained stormwater, since the stormwater flushes the contaminants from impervious surfaces (Stenstrom and Kayhanian 2005; Baek et al. 2015; Duan et al. 2016). What is more, the analysis of Toronto and Region Conservation Autho
