Well if your only definition of sanitation is urban ones, then they had that as well as I pointed out. I think the fact that they had sanitation practices in both urban and rural areas is quite remarkable. Clearly you don't and felt the need to share that opinion. Thanks.
Please reread the comment you just responded to. I said it was remarkable (as in, worthy to be remarked) that these practices happened both in urban and non-urban cultures.
The North American cities were certainly more advanced in terms of sanitation than anything in Europe at the time. You had stuff like dual aquaducts differentiating drinking water from washing water and public cleaning crews and urban waste maangement and people bathed daily. While London was throwing its shit in the streets, the Aztecs were building public toilets
