Abstract

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks. Today more often simpler and more natural solutions are looked for to delay the transport of storm water on the ground. In such processes you can by means of the soil and its plants treat the water before it reaches the drain system and finally the recipient. The object of this work was to get a picture of methods used today to solve problems with storm water in cities and to look for their advantages and disadvantages. In this work the pollutants of storm water are described as well as their effects on the recipient. Some common methods to delay flooding storm water have been shown, also possible recirculation ideas are discussed
