Classroom survey to gauge how the three pillars of sustainability are prioritised for the urban water and wastewater system / Klassrumsundersökning för att mäta hur de tre pelarna för hållbarhet prioriteras för urbana vatten- och avloppssystem
This brief article presents the results of a survey conducted by the author during a lecture on ‘Holistic Approach to the Study of Water and Wastewater Systems,’ as a part of the course – Treatment Technologies (Reningsteknik), taught in the Department of Chemical and Engineering Sciences, at Karlstad University (Karlstad, Värmland, Sweden). While all the respondents – there were 23 of them – valued the social aspect the highest – perceptible differences were seen in the way the weighting factors were assigned, even among respondents hailing from the same city. A total of fourteen cities were represented by the 23 students surveyed. The grand average was 41.1 % (social), 32.6 % (environmental) and 26.3 % (economic).
