WaterMet2 conceptual model report. (Deliverable D33.1)

© TRUST 2012Building on the WaterMet2 functional requirements report, this report presents the comprehensive concepts behind the processes and components of the WaterMet2 model that will be developed to quantify the generic Urban Water System (UWS) metabolism based performance model in the TRUST project (TRansitions to the Urban water Services of Tomorrow). This report is a project deliverable to describe different components and subsystems and their functionality in more details. Two main aspects of the WaterMet2 model are addressed here. The first part of the report illustrates the principal modelling concepts which will be used in the WaterMet2 model. The UWS is characterised using four different spatial scales together with temporal resolution concept for time step modelling. Then, principal flows in the WaterMet2 model along with two main aspects of water modelling (i.e. water quantity and quality modelling) are described. The second part presents a more detailed description of modelling of components and processes in the WaterMet2 model: (1) water supply and distribution; (2) water demand; (3) wastewater and (4) cyclic water recovery and resource recovery. For each component, all input and output flows along with the associated parameters and variables used for modelling of the intended components are described in detail. This document is based on the authors' current best understanding of the UWS metabolism concept and the associated performance related issues. Therefore, as WaterMet2 model development progresses, information presented in this report may evolve and change.European Union Seventh Framework Programme (FP7/2007-2013
