It seems as though if they're properly (and regularly) maintained, they don't clog. Sounds like your university's periodic (compared to acute - think janitor) maintenance workers were improperly trained on how to care for them. The second page of the article explains this.
(edit: on second thought, it was a university. Knowing what university students tend to put in urinals, I'm not surprised they clogged even with proper maintenance)
- _delirium 16y agoI agree it's probably possible to maintain them well, but it seems it's still a cost. If nothing else, you have to pay for better maintenance workers, or more oversight of them.
- brianpan 16y agoI've seen these toilets in action and from my few encounters, they work as advertised. But after reading about how they work, I have reservations on the design. Depending on maintenance for keeping sewer gases from escaping seems failure prone. Humans err (and get lazy). I'd much rather depend on plumbing codes that have been tested over decades and work "automatically" than depending on changing a cartridge. What happens if a bathroom with a waterless toilet is abandoned or isn't maintained regularly?
- inferno0069 16y agoThe traditional U-trap can fail if abandoned or isn't used regularly too. The water eventually evaporates.
- misterbwong 16y agoThey should design a "self cleaning" model that actually uses the piping behind the urinal to flush once a week or so. It seems like this would resolve the need to rely on human maintenance, although the urinal wouldn't truly be waterless anymore.
