This document summarizes two wastewater reuse projects in France - the Irrialt'eau project, which treats wastewater for reuse in irrigating vineyards, and the NOWMMA project, which optimizes wastewater treatment processes for reuse. It also outlines Ecofilae's role in assessing and developing wastewater reuse solutions, and their expectations to contribute indicators for comparing different reuse projects between regions and develop online tools to communicate about reuse.

• Description of one of the two pilot-scale sites in France
(Irrialt’eau) based on the available data OR a general analysis
of wastewater reuse in Languedoc-Roussillon
• Tools for Development of a detailed matrix with
indicators/benchmarks for sites crossed comparisons
(projects from the 4 regions)
Objective : making different water reuse chains comparable
• Tools for communication: Online web system
vizualization/valorization/exposition (Map'reuse) for
communication (Alera Toolbox)
