A Life-Environment project (AQUASAVE), funded by the European Commission, with the aim of implementing an integrated system for saving, recycling and reusing water in an apartment building, has been recently concluded. For evaluating the environmental sustainability of introducing water-saving devices, rain-water harvesting and grey-water reusing technologies in domestic water cycle, the global environmental impact of existing drinking and wastewater treatment systems of Bologna city has been estimated by means of LCA methodology. In each technical process of Bologna water cycle the energy, chemicals and materials flows and the related emissions to air water and soil have been evaluated. The results have been compared with an "innovative" scenario in which the existing domestic water cycle has been modified by introducing AQUASAVE techniques. For a correct comparison of the two studied alternatives, the use of rain water in washing machines and the subsequent potential reduction of detergent consumption has been included in the systems boundaries. Life cycle impact assessment results confirm that the dominant process for the most important environmental impact categories, except eutrophication, is the production of electric energy needed for drinking and wastewater pumping. In this paper, after a short description of the AQUASAVE project, the analysed systems are described, the methodological approach and the final results of the study are discussed.
