My town pays for sewer (which I don't have) and water (which I do) out of property taxes, assessments, and a quarterly water bill. I pay Comcast for my own Internet and I pay for private trash. Property taxes also pay for education (a big chunk), snow plowing, police/fire/library, etc. There's some money to roads but, yes, that's mostly from the state and gas taxes which residents also pay of course. So it's not like cities are picking up the whole bill; while they have more people paying taxes, a lot of costs are much higher as well.
