Question

How long will a typical cartridge last in a waterless urinal in a busy high school washroom?


Answer

Until it's changed. On a more serious note, some people have been raising questions about the true value of waterless urinals due to high maintenance costs and other problems. Search Google for "waterless urinal problems or costs" and see what you find.
You could also contact waterless urinal manufacturers and ask them your question, I'm not sure how accurate an answer you'll get. “Busy” is not as definitive as “50 uses a day” or some such count. They may have some figures to share with you and can point you to installations similar to yours so you can compare notes. For the most accurate numbers check with others, who have been using them for a year or two and don't sell them.
