Quantitative UWS performance model: WaterMet2
TRUST (TRansitions to the Urban Water Services of Tomorrow) Project
The report presents a detailed description of the WaterMet2 methodology and tool as a quantitative urban water system (UWS) performance model. The WaterMet2 model is described in three distinct parts. Modelling concepts of different components in WaterMet2 are first described. It provides an overview of the principle flows/fluxes modelled in spatial and temporal scales in WaterMet2 and how they are modelled within the framework of mass balance equations in four subsystems (water supply, sub-catchment, wastewater and water resource recovery). The second part describes the WaterMet2 software. This consists of an overview of WaterMet2 on how input data are prepared, how to run a simulation and finally how to retrieve results in different formats. This part also introduces the WaterMet2 toolkit functions which can be used by other programming languages to call a WaterMet2 simulation model. In the third part, WaterMet2 is illustrated using the city of Oslo UWS as a generic reference model. This part first describes building and calibrating a WaterMet2 model for the existing UWS which faces water scarcity problems for a 30-year planning horizon starting from year 2011. Then, it examines two alternative intervention options (i.e. adding new water resource and water treatment options) which are supported by the WaterMet2. These options are examined for the UWS model and the improvements are compared to the business-as-usual case.
