As part of AQUASAVE project, funded by the European Union in the framework of the LIFE-ENVIRONMENT action, an assessment of the environmental sustainability of innovative techniques of water consumption reduction, rain water harvesting and grey water reuse in a residential building of Bologna has been recently initiated.The aim of AQUASAVE is to design and build an apartment house in Bologna, to demonstrate, trough the introduction of appropriate devices and technologies, the possibility to save up to 50% of drinking water. The idea is to use treated grey water for toilet flushing and rain water, after treatment and storage, in dishwashers and washing machines. Moreover, devices for reducing water consumption will be extensively adopted.The environmental benefits and burdens of introducing these systems in a residential building without changing the municipal wastewater treatment system will be evaluated by mean of an LCA analysis.In the first phase of the study an LCA of production and distribution of drinking water and of treatment of waste water of the entire Bologna municipality has been performed.This activity has been conducted in collaboration with Seabo, the municipal firm that has in charge the whole water cycle of the Bologna city.In the second phase the introduction of the proposed domestic systems will be evaluated.In this paper the preliminary results of the study will be presented.

Abstract

As part of AQUASAVE project, funded by the European Union in the framework of the LIFE-ENVIRONMENT action, an assessment of the environmental sustainability of innovative techniques of water consumption reduction, rain water harvesting and grey water reuse in a residential building of Bologna has been recently initiated.The aim of AQUASAVE is to design and build an apartment house in Bologna, to demonstrate, trough the introduction of appropriate devices and technologies, the possibility to save up to 50% of drinking water. The idea is to use treated grey water for toilet flushing and rain water, after treatment and storage, in dishwashers and washing machines. Moreover, devices for reducing water consumption will be extensively adopted.The environmental benefits and burdens of introducing these systems in a residential building without changing the municipal wastewater treatment system will be evaluated by mean of an LCA analysis.In the first phase of the study an LCA of production and distribution of drinking water and of treatment of waste water of the entire Bologna municipality has been performed.This activity has been conducted in collaboration with Seabo, the municipal firm that has in charge the whole water cycle of the Bologna city.In the second phase the introduction of the proposed domestic systems will be evaluated.In this paper the preliminary results of the study will be presented.
