Abstract
A Life-Environment project (AQUASAVE), fimded 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 watersaving
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 techmcal 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"
