The fulfillment of the Millennium Development Goals in terms of sustainable access to sanitation requires increasing the development of research programs that promote simple and low cost technological options, appropriate to the social, economic, and environmental conditions of each population. These processes must be accompanied by actions of environmental and sanitation education, which allow appropriation of these systems by the communities. In this sense, there are two projects in the National University converging on this subject. The Museum of Popular Culture together with the Public Service Company of Heredia develop an environmental education project that promotes the protection of water, from an historical perspective of its management, which has an artificial wetland as the main teaching unit. On the other hand, the Waste Management Laboratory at the School of Chemistry evaluates the performance of this artificial wetland as part of a research project that promotes this type of alternative sanitation. This paper presents results of the monitoring of this artificial wetland, showing average removal percentages of 93% BOD5,20 , 95% COD, 73% P-PO4, and 95% for SS.
