This report - D34.2, authored by NTNU, is a sequel to D34.1 in which interventions suggested by the water-sanitation utility in Oslo - Oslo Vann og Avløpsetaten, had been tested using both the models-the WaterMet 2 (WM2) model developed by Exeter and the Dynamic Metabolism Model (DMM) developed at NTNU, as part of TRUST. The report starts off by emphasising the need for a holistic long-term sustainability approach in decision-making in water and wastewater utilities around the world. The models referred to above, are proposed as aids in meeting this need. With the help of references to earlier published works and TRUST deliverables related to these models, as well as some new tests carried out using one of them (DMM), the usability of the same has been demonstrated. 'Usability' here refers to understanding the impact of interventions on selected metrics/indicators in year-2040 (in keeping with the title of the deliverable; and the timeframe which has been considered for the TRUST project); and subsequent choices/selections which utilities would like to make depending on their priorities, targets and benchmarks they would set for themselves. As concluded in D34.1, there are differences between WM2 and DMM - which make them useful in different contexts - situational, circumstantial etc. These differences are recounted here again, in order to make it clear to the readers and end-users that one model is not meant to substitute the other, per se. Simply put, depending on what the end-users' needs, goals, objectives and constraints are, one or the other would be preferable. The models have been extensively tested at Oslo VAV.
