Discharge of untreated waste waters into surface waters creates significant pollution in these resources. Wastewaters are most of the time discharged into seas, rivers and other water bodies without any treatments due to high treatment costs both in Turkey and throughout the world. Constructed wetlands, also called as natural treatment systems, are used as an alternative treatment system to conventional high-cost treatment systems because of their low construction, operation and maintenance costs, energy demands, easy operation and low sludge generation. Today, constructed wetland systems are largely used to treat domestic wastewaters, agricultural wastewaters, industrial wastewater and runoff waters and ultimately to prevent water pollution and to improve water quality of receiving water bodies. In present study, currently implemented practices in design, construction, operation and maintenance of constructed wetlands were assessed and potential mistakes made in different phases these systems were pointed out and possible solutions were proposed to overcome these problems.
