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.

洪水泛滥和排水水质恶化是快速发展的城市地区的主要问题，主要是因为城市化减少了自然地面可以吸收雨水的区域，因此可以防止洪水和污染。为了提供能够解决这些问题并且对于自然界和人类可接受的解决方案，开发并应用了分散排水系统。分散系统的主要目标是改善雨水的渗透，蒸散和再利用。这项研究提出了三种不同的大气雨水管理解决方案的分析。分析的解决方案基于经典的污水处理系统以及城市地区（塞尔维亚库切沃）应用的低影响开发（LID）技术。由于佩克河是多瑙河的支流之一，因此该分析的主要目的是确定减少污染物和减少排放的大气水并使用雨水管理的试验程序。在分析所有解决方案之后，仅基于LID技术的第三种解决方案（植物沼泽，渗透沟，雨水桶和生物保留池）给出了最佳结果。根据仿真结果，在第三种解决方案中提出的技术可以完全去除雨水和雨水过剩中的所有污染物。雨桶和生物保留池）效果最佳。根据仿真结果，在第三种解决方案中提出的技术可以完全去除雨水和雨水过剩中的所有污染物。雨桶和生物保留池）效果最佳。根据仿真结果，在第三种解决方案中提出的技术可以完全去除雨水和雨水过剩中的所有污染物。
