If you are against implementing sewage/feces management in DF I'd advise first looking up some books in sanitaiton and urbanism.
ONE OF MANKIND'S GREATEST URBANISM PROBLEMS ALWAYS HAD BEEN SEWAGE MANAGEMENTSewage is something we probably take for granted, but if you look back in history, what really was a major obstacle for the higher population concentrations on cities has been managing the sewage. The romans did it somewhat well, then we had medieval times where people threw buckets full of excrements, dirt, and litter, through the window. Not coincidentally the medieval cities were plaugued with epidemics of several diseases that are transmitted from general lack of sanitation.
In the industrial revolution the even greater concentrations of workers and such led to great outbreaks of cholrea for instance, (and tuberculosis, although this one is just a disease problem, not really related to sewage). The sanitation movement started after it was discovered that contaiminated water was the source of cholera in the 1800's.
Back to the point, i think it would be amazing if we had to manage sanitation for our fortresses, considering they are incredbly packed agglomerations of people. Not only excrements, but for instance, kitchens, tanneries, farmer workshops and butchers should need a sewage connection to dump some of their waste. For those too
pansy sensible about the word "feces", just call it sewage.
Obivously considering how we have a contaminant chaos in the current version, I'd rather see the whole system be overhauled somewhat before we implemented sewers, due to the obvious problems and chaos it could lead.
It amazes me the schyzoid sense of humor some people in this forum have. While we all worship the almight "Fun" with self-degratory irony and such, it seems most of those "OMFG SHIT? NO!!!!" people don't even recognize a good part of the pro-sewage voters mentioned drowing invaders in sewage more as a joke than a real fort mechanism. Of course, flows in dwarf fortress are always used as drowing tools, and this is a new kind of flow people wouldbe interested with, there's a whole novelity issue with this. I imagine a lot of people would post their sewage drowing traps eventually, but it is not like we would be drowing in such threads if such a thing was implemented. For me the "overflowing forums with shit trap threads" excuse is just a half-baked lame excuse for people being impeded by their own repressoins and taboos about a doubtlessly bothersome (if not awkward), but nevertheless absurdly relevant aspect of life.
