An experimental study was performed on a full-scale treatment plant consisting of screening and primary sedimentation followed by two-stages constructed wetlands. The aim of the study was to assess its suitability for the treatment of the domestic sewage from the small communities (up to 1000 population equivalent, PE) located in the State of Bahia (Brazil). The proposed depuration plant showed a very high removal efficiency of COD, BOD5, suspended and settleable solids as well as of the microbiological load. The favourable weather conditions promoted high vegetation and degradation rates in the basins, and therefore it was possible to rise the influent load. The sale of the tropical flowers produced by wetlands provided the people with a good income, whereas the effluent was reused in agriculture for watering the communities’ vegetable gardens.

3rd IWA Developing Congress & Exhibition. Catalysing Urban Water Transition
An experimental study was performed on a full-scale treatment plant consisting of screening and primary sedimentation followed by two-stages constructed wetlands. The aim of the study was to assess its suitability for the treatment of the domestic sewage from the small communities (up to 1000 population equivalent, PE) located in the State of Bahia (Brazil). The proposed depuration plant showed a very high removal efficiency of COD, BOD5, suspended and settleable solids as well as of the microbiological load. The favourable weather conditions promoted high vegetation and degradation rates in the basins, and therefore it was possible to rise the influent load. The sale of the tropical flowers produced by wetlands provided the people with a good income, whereas the effluent was reused in agriculture for watering the communities’ vegetable gardens.
