"Isn't that why the government has the power of taxation or the ability to levy fees?"
My point was that some taxation is based on usage, so charging those using the utility would make sense. This would mean still charging the people connected. Otherwise, who would the government tax to subsidize these other citizens?
I've seen it done this way for many different projects.
Thats literally the opposite of how taxes work. What you are describing is called charging the customer.
Taxes are paid independant of usage, my taxes pay for schools wven if I dont have kids. Someone with 10 kids but less income pays less taxes for schools.
False.
That's only one example of a tax. How about gas taxes to pay for the roads they use?
In the US, the latter two are not broadly considered necessities in rural areas. The situation varies but wells, where possible, and septic systems are extremely common away from urban metros and towns of a certain size.
In any case, water and sewer are indeed considered necessities and you are unable to sell or convey a house in the state that I live without a functional water or sewage system, whether on public water/sewer or on well / septic. If you have a non-functioning well or non-functioning septic (outhouses are no longer allowed), then you can't sell your house, and also you are in risk of having your own house condemned. So these are indeed necessities.
