Abstract: One of the bottlenecks for the development of source-separating wastewater systems is the uncertainty among stakeholders about end-users’ acceptance of new sanitation systems, such as vacuum toilets due to the limited information about it. This study explores public perceptions and investigates whether individuals, as end users, are willing to pay for vacuum toilets through discrete choice experiment. Two workshops and one pilot study were held to test the understandability of the questionnaire. Preliminary results identify a willingness to use vacuum toilets with a preference for those that generate less noise.
