I guess that would depend on where you live. In Chicago the drinking water is pulled from
Lake Michigan but the waste water is discharged into the sanitary canal which sends it into a system of waterways eventually going to the Mississippi river
Lake Michigan flows through the Chicago River and (eventually) into the Mississippi. It didn't used to, but you can thank the Army Corp of Engineers for that.
​
AFAIK, with a few exceptions (like Chicago) there's an international treaty for the Great Lakes that requires water/excess used by humans to be eventually returned to the lakes.
