Don't get me wrong, I think the bills are ridiculous, but that's what I've been seeing in my rentals for yrs and when I used to live in the city. I think years ago mine were about $70/mi and it slowly crept up to $120 - $150.

Water bills are public info, so you can see for yourself by punching in your neighbors addresses. I've done that and found an alarming amount of my neighbors were behind thousands of dollars.
