Designing Sustainable Wastewater Systems: Visual, Interactive Preference Elicitation

The majority of water and wastewater infrastructures in the industrialized world will require retrofitting and replacement in the near future. Furthermore, there is a growing need for new infrastructure in developing countries. Growing environmental and energy concerns in combination with the challenges involved in securing the quality and quantity of water heighten the urgency of the issue [1-3]. Thus, identifying sustainable solutions requires the simultaneous consideration of economic, ecological and social goals. The challenge is considerable; it is a context-dependent multi-dimensional, multi-objective decision problem in which competing objectives must be identified and trade-offs made [4-7].
