When the water evaporates it leaves behind the minerals so it builds up quick. There’s maintance that you have to do on them and depending on the place there are regular water changes since the minerals build up. Places that have hard water I would assume change more often plus there is legionnaires from the water too since it’s a good environment for bacteria and other shit. Which can also get put into the air as droplets and assuming you have a humid day it could also make the workers or people near sick. Plus water usage can vary since maintance is not always top priority for companies so a bad float valve can passively just dump water back into the city system
