Abstract:Water shortages are becoming a more common problem, even in the Netherlands which is considered a “wet country”. Water should not be wasted and a possible method to save a lot of water is the dual flush toilet. This toilet allows for a large flush for solid waste and a small flush for liquid waste, by using this small flush a lot of water can be saved. However, not everyone always flushes correctly and water is still being wasted. This project focused on making the UT community more aware of their flushing behaviour which might hopefully lead to behaviour change. A prototype system was developed that uses memes to provide feedback about the user’s flushing behaviour. Memes fit the target audience of the UT community well (80% students and 20% staff)and allows to provide contextual information to be provided in a fun way that can remain interesting. This contextual information can explain about proper usage, water usage, consequences and comparisons. The system consists of an instrumented normal dual flush panel, a micro-computer and a colour display. The micro controller uses the flush panel input to select an appropriate meme. This system was placed in both a male and female toilet in the UT’s Ziverling building were users were asked to fill in a questionnaire to see if their awareness has increased. From this survey with 19 respondents, it was concluded that it did raise people their awareness of their flushing behaviour and that some users plan to use the small button more often.
