Review.Advances in the management of the wastewater in Turkey: natural treatments or constructed wetlands

As a result of rapid population growth and industrialization with increased water demand, domestic and industrial waste has increased. Wastewater left to streams and rivers without treatment is polluting the environment. The purpose of this study is to explain the importance of the constructed wetlands for wastewater treatment and to provide information about applications in Turkey. In this study, constructed wetlands have been introduced, the types, operation systems, performance evaluation, information about the legal regulations for use of waste water in agriculture has been given. Municipal wastewater can be reused with constructed wetlands in rural areas and water saving will be provided. The constructed wetlands should be developed rearranging Turkeyʹs laws. Thus water used for agriculture will be reduced and other sectors needs will be met.
