The project intends to develop integrated strategies for the reuse of upgraded ef-fluent from wastewater treatment plants (WWTP) as a fresh water substitute for non-potable use. It will provide standards, recommendations and data for policy makers (strategy level), methodologies, practices and guidelines for preparing and operating reuse systems (management level) and design standards and cost data for proven reuse process chains (technology level). Case and feasibility studies serve to substantiate and validate the results. The consortium consists of 23 partners from 12 countries and integrates fields as diverse as economics, environmental science, medicine, hygiene, geology, chemical, systems and civil engineering. Innovation is expected mainly from novel targets (inclusion of pre-accession states, focus on multi-purpose industrial reuse), application of best available tools from many disciplines, user oriented approach and introduction of hybrid processes.
