I'd be really opposed to this. It'd only be ok if we nationalized the industries where we set these rules and rates. Otherwise, this ends up being a simple handout to private industries.
For example, let's say we say x liters of water. Well who's deciding how much x liters cost? If it's a private company and the government is guaranteeing it, you can bet water (which is relatively cheap where I live) will end up being the most expensive resource imaginable. And that may actually be true depending on the location, but it'd also be true in non-desert areas with plenty of water.
We've effectively had that here with the ACA, where the government has decided that it will cover the first $800 or so dollars of your health insurance. What happened? Magically, the cost of health insurance increased by $800. Private industries aren't stupid, they'll always charge the maximum price the market will bear. And when we start talking about captured industries like data provider, power provider, or your water provider... well that's where we can trust private industry the least as they literally have the public over a barrel. Utility boards are an OK solution, but the better solution is to turn these into public institutes instead of private ones.
