Constructed wetlands, institutional aspects, performance, sustainability


This paper reports about a study assessing the performance of two constructed wetlands which were implemented within a program for the recuperation of Lake Patzcuaro in Mexico. Both treatment plants contribute to the protection of the Lake Patzcuaro and confirm that constructed wetlands are an appropriate technology for treating domestic wastewater of small communities. The evaluation covered institutional, technical and economic aspects. However, organizational issues and the habit of users throwing garbage into the sewer endanger smooth operation for the future.
