Methodology for systems analysis of sustainable wastewater management - assessment for an urban catchment in Vasastaden, Göteborg.

Paper in proceeding, 2004

This paper presents a methodology, i.e. a scheme of methods and principles to be used in systems analysis of alternative wastewater systems. The methodology is tested in a case study for an urban catchment where three different system structures for management of wastewater were compared: a combined sewer system, a conventional separate sewer system, and a source controlled separate system. The outcome of the step-by-step methodology is an overall assessment of the sustainability in each of the studied systems, which can be used as support in a decision-making process. The tools and methods have also proven to be useful in evaluation of different scenarios, especially in relation to source control.
