ABSTRACT
This article illustrates the use of life-cycle analysis (LCA) in wastewater treatment systems. The regulation on water is briefly recalled notably concerning residual waters, sanitation systems and the conditions for the discharge of urban effluents. The principal technologies implemented in wastewater treatment installations are presented. The stages of the LCA process are also listed: definition of the objectives and of the field of study, inventory, impact analysis and interpretation of results. To conclude, an example of application, based upon the simulation of two different treatment scenarios is provided.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
This dossier illustrates the use of life cycle assessment (LCA)
After an overview of water regulations and a brief presentation of the main technologies used in urban wastewater treatment plants, the steps involved in LCA are summarized. An application example, based on the simulation of two treatment scenarios, is presented and discussed.
