City of Phoenix Water Bill 4 plex

[James Conaway]

I have a 4 plex that is fully occupied and is averaging around $350 a month for sewer/water/trash. The sewer fee is about 1/3 of the overall bill. I am being told by a nearby landlord with identical buildings that the portion of his bill for sewer is a 3rd of mine. His total bill averages around $220 a month, with the sewer portion approximately $35.

I am going to talk to the city to find out what options I have to get it adjusted, I was curious to know from other landlords with 4 plex's in Phoenix how much of their water bill from the CoP is due to the sewer fee?
