Wetlands provide inherent self-treatment service of the nature through on-going complex physiological, chemical and biological processes in them. Today, constructed wetlands, created through imitating these processes of natural wetlands, are widely used in treatment of domestic waste waters. Constructed wetlands with specially design basins filled with substrate filter materials and planted with aquatic species can remove various pollutants from domestic waste waters. 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 waste water characteristics, site geography and climate conditions should be considered in design, constructions should be carried out precisely and operation-maintenance-monitoring activities should also be followed all to meet the desired performance expectations. In this study, the parameters to be considered in design, operation, maintenance and monitoring of constructed wetlands used for domestic waste water treatment were pointed out and common failures observed especially in constructed wetlands of Kayseri province were indicated.
