10 yrs at a waste water treatment facility. There is no place that doesn't smell bad. When I was new I could even smell it in the lunch room. Eventually you get used to it. You always smell it but much like your own farts it's not a bother. I've had to remove animals (deer and dogs) from the coarse screens at times. Thats a combo effect of death and sewage. Sometimes the closer you get to the source, the worse the smell. If you think you've had a bad day at the office try crawling a sewer not much larger than you and getting to the upstream manhole standing up and being covered in EVERYTHING one flushes down the toilet. I've had used tampons, pads, condoms found in my pocket or stuck to me, much less the feces.
I did some time as a sexton at a local graveyard. The liquids that leak from the vault next to the hole I would be preparing for the current burials was a odor so far unmatched by anything I've been around. Jumping down in the plot to corner and level out after said leakage always resulted in getting it splashed on my clothing. It would take many a wash cycles to get the smell out. Some people request not to be embalmed (religious reasons I suppose) and that always presented a time sensitive situation before the odor became very noticeable.
