Work Area 1 contributes to the overall objective of TRUST by performing an initial assessment of the urban water situation in Europe, going also beyond the TRUST pilot regions. It will suggest a solution-oriented planning approach that will ask four key questions: Where are utilities now? Where do they want to be? How might the utilities get there? How does it ensure success? The planning towards sustainable urban water cycle services (UWCS) should be realised as a road mapping process, for later application to all the TRUST pilots.
The main objective of TRUST is to support water authorities and utilities in Europe in formulating and implementing appropriate urban water policies in order to enhance urban water cycle services. The specific objectives of Work Area 1 are to conduct rapid research and evidence reviews highlighting research activity, best practice, current initiatives and knowledge gaps/research challenges in the area of urban water cycle systems. Another specific objective is to investigate future pressures and trends that will impact the urban water systems and investigate how global water utilities are responding to these pressures. The last task of this Work Area is to develop a generic roadmapping process and structure for determining the best path for transitioning from their present situation to the desired future endpoint.
The TRUST Approach
For Work Package 1.1 the methodology proposed for establishing 'what works' in relation to sustainable urban water management will be rapid research and evidence based reviews. These reviews will ensure that the TRUST project is informed by the latest research and information on best practice. These systematic reviews will aim to identify, evaluate and summarize the findings of all relevant studies, thereby making the available evidence accessible to other work areas in TRUST. The review will employ a structured multi criteria analysis (MCA) approach that will involve identifying appropriate performance and sustainability attributes and indicators for the different dimensions of urban water systems.

In Work Package 1.2 one of the main objectives is to establish the future pressures and trends that will impact the urban water systems. To achieve this, a detailed review will be undertaken of recently completed research studies (e.g. SWITCH, TECHNEAU). In particular, the review will consider the state of the art in relation to urban scale predictions and the associated uncertainties and flexible and adaptable systems that are capable of handling these uncertainties. This review will be coupled with a detailed analysis of how European water utilities are preparing long-term strategic plans for delivering services for the next 30-50 years. It will also consider the transitioning process which is being proposed, and the roadmap for the water utility.

The outcomes of the above work packages will support Work Package 1.3 that will focus on the development of both structure and process for an effective UWCS adaptation roadmap, using a DPSIR (Driving Forces-Pressures-State-Impacts-Responses) assessment framework. For the several stages of the roadmap process, generic protocols, guidelines and templates will be provided.
