Presently in landscape natural swamp ecosystems owing to their organic and inorganic suspension's holding capacity and biodegradability create both invaluable and unique environment. With reference to these ecosystems constructed wetlands came into being in which water with a high amount of suspensions treatment tasks are realized effectively. The constructed wetlands, grooved with properly selected plant species blend into the natural landscape. Their effectiveness, stability and naturalness mean they are more often in grace and can be perceived as an alternative to traditional water treatment systems.
