Summary of methods, rules and criteria to be incorporated into the Decision Support System

Abstract

An impact assessment methodology for evaluating the qualitative impact of urban water technologies and methods on objectives and criteria of the TRUST sustainability dimensions (social, environment, economic, governance issues and assets [1]) is described in this report. The relevance of selected technologies and methods is assessed in terms of being enablers or barriers for the realisation of the TRUST sustainability objectives. In general, the assessed technologies and methods focus on improved planning and more sustainable operation of urban water cycle services. The main focus on methods (e.g. operational options) and technologies (incl. new technologies, tools, equipment) investigated in TRUST (WA 4) lies on optimising processes, improving process control and best operation practices within the perspectives of sustainability and life cycle assessment. This summary of methods, rules and criteria for decision making includes the use of resources in the fields as follows: • Enhanced water treatment processes (WP41) • Urban water use management (WP42) • Wastewater and storm water management in urban water systems (WP43) • Enhanced utilisation of alternative water sources in urban water systems (WP44) • Water-energy nexus in urban water systems (WP45) • Enhanced technologies for infrastructure asset management (WP46) The report is mainly addressed towards the scientific community as well as the scientists involved in TRUST. The framework for impact assessment on TRUST objectives can be used for individual and case-specific evaluations.
