Anecdote unrelated to your point: I’ve grown up close to a sewage treatment plant and have been taken on a couple hours’ tour of it in middle school. And what do you know, while there is a faint odour in the air (much weaker than, say, near a barn or a stable, but it’s there), it’s one of the most sparkling-clean, meticulously organized workplaces I’ve seen before or since. I’ve been to chemistry labs with worse plumbing and more clutter than that, let alone industrial facilities. I mean, it’s not that surprising in hindsight—if it’s clean everything or drown in literal shit, you bet it’s going to be clean. But it’s definitely not what I expected. (Probably helps they didn’t get their funding or wages cut while the surrounding country was falling apart, chemistry labs and all, for the same reason.)
