Measuring the predictors of communities' behavioural decisions for potable reuse of wastewater.

This paper follows from a previous one by the authors which described the development of a behavioural model to predict community intended behaviour in relation to proposed wastewater recycling schemes where close personal contact is involved. This paper now outlines the confirmation of the robustness of the model for use as a tool by proponents of such recycling schemes, and to provide details of the model's indicator measures, including the "yuck factor", to allow easy applicability to future developments. It outlines the individual items that are asked in a questionnaire format, and provides evidence of the reliability and validity of the measures. The model was replicated and again proved to have a powerful predictive capability. The paper concludes by suggesting how the model can best be used as a tool in the planning and implementation of wastewater reuse schemes and the next steps in gaining public acceptance, particularly for indirect potable uses.
