Water reuse projects can fail if the factors (social, technical, financial, etc) governing their implementation are not adequately addressed prior to implementation. This paper presents the findings of the analysis of questionnaires administered to potential domestic and non-domestic consumers in Capricorn and Vhembe (Limpopo Province) where wastewater reuse was being considered. The analysis examined the factors considered to predict the to accept wastewater reuse prior to implementation. Structural Equation Modelling (SEM) was employed to test several hypotheses addressing respondents' to accept wastewater reuse for non-potable end uses. In other words, SEM tested whether certain factors (e.g. trust, attitudes and control) measured . was measured as a second order factor. For non-domestic respondents, the factors that predicted to accept wastewater reuse in order of significance were their , the degree of , the respondents' and the respondents' . For domestic respondents, the factors were their , the degree of , , , and the of the respondents. (for both respondent categories) and (for non-domestic respondents only) could not be assessed because a reliable scale was not formed. The above findings have implications for future wastewater reuse in South Africa, i.e. that decision-makers contemplating reuse for non-potable uses would profit from addressing the various factors predicting to accept reuse prior to implementation.
