Natural wetlands with various on-going complex physiological, chemical and biological processes in them, provide
inherent self-treatment service of the nature. All these treatment processes are imitated in constructed wetlands.
Constructed wetlands, so called as natural treatment systems, are widely used for treatment of domestic, industrial and
agricultural wastewaters. The constructed wetland technology is composed of specially design basins filled with
substrate filter materials and planted with aquatic species, inlet and outlet structures to regulate the flow regime within
the basin and to remove various pollutants from the wastewaters. In case relevant criteria were not taken into
consideration in design, operation, maintenance and monitoring of these systems, irremediable or irreversible failures
are evident. Therefore, national and international standards, influent wastewater characteristics, site geography and
climate conditions should be considered in design, constructions should be carried out precisely and operationmaintenance-monitoring activities should also be followed to meet the desired performance expectations. In this study,
use of constructed wetland technology in domestic wastewater treatment was explained and potential mistakes made in
design and operation of these systems was pointed out.
