A place to dump sewage that isn't the side of the road doesn't necessarily mean indoor plumbing. I just noticed "manhole covers" for lack of a better way to describe them as I was walking down the road in Solitude. I know Romans basically had benches with holes in several of their public places where the refuse went somewhere below. I don't recall the standard medieval domicile having anything of the sort. They went the chamber pot route.
Side note: Because skeeveraway just doesn't have the same flair?
