Up to the present days climate change is without a doubt becoming the most significant environmental issue. The harmful effects of climate change are especially evident in urban spaces which are due to the specific conditions even more vulnerable than surrounding landscape. Therefore, it is essential to adequately reflect this difficult situation within both current and future development. One of the most affected natural sphere in the cities is certainly water regime. Constantly growing share of the urban population increase the press for sufficient water stores at the same time when extended building density threaten or even destroy them. Majority of watercourses in the urban areas are nowadays substantially transform and unfortunately also contaminate by surrounding neighborhood, which lead to declining reserves as well as worse quality. Consequently, it is necessary to find and use some alternative sources with a potential to refill this reducing water stores. One of the most commonly used approach could be use of a stormwater. This method includes many important benefits such as the effortless availability or economic accessibility. On the other hand, many disadvantages within natural or administrative barriers could also appear and surprisingly that administrative obstacles prevail the first named in many cases. This research focused on a concrete type of stormwater management project, namely biofilter systems. By an example of three Israeli pilot projects is described how these systems (does not) works. Afterwards, ascertained advantages and disadvantages become the important factor which could be helpful in decision-making process related to implementation of biofilter systems in other states and even different climate conditions across the world. Following the findings from Israel this research also proposes the case study of practicable and successful implementation of biofilter system in one selected city in the Czech Republic.
