Wastewater treatment in developing countries is a problem of access and efficiency. Individual wastewater treatment systems are important when the sewage collection network does not reach the whole community. Therefore, the treatment efficiency should be evaluated when considering systems design and the prevention of environmental negative impact. Wetland’s systems are often used as final treatment for wastewater polishing. This work proposes a wastewater treatment using a hybrid system consisting of septic tank, anaerobic filter, and a wetland system using plants as tertiary treatment. Samples were collected to evaluate biochemical oxygen demand (BOD), chemical oxygen demand (COD), turbidity, apparent colour, total solids, total phosphorus (TP) and nitrogen. In two points analysed the contaminant removal was a result of septic tank set with the anaerobic filter. The efficiency of the system was recognized to improve the quality of the final effluent, showing as an excellent alternative to countries with lack of collective structures for the treatment of domestic sewage.
