We don't directly recycle treated wastewater into drinking water much in the US. The closest you get is treated water being released into a river, and a city downstream uses it, there's a lot of dilution going on in-between. You'd also expect someone to notice it not affecting cities with water supplies that aren't downstream from wastewater treatment.
