The difference between the sewer and broadband is that the price of giving sewer district a monopoly is regulation as a public utility.

So if whomever runs your sewer decides that they will not accept solid waste anymore, there is a regulator who will prohibit that from happening.

In many states, the Public Service Commission or similar entity has lots of regulatory authority over cable television, landline and electric rates, but no authority over cellular or broadband. Shockingly, the utilities have invested nothing in the regulated markets for 20 years.
