I think I'm gonna to go ahead and assume what you are saying is 'why isn't the state and:or city already handling this' just more poorly worded.
I'm going with that because I want to take a moment to highlight this is one of the things that is very wrong with American infrastructure. You see most states aren't like the federal government in that they are often competing with other states for things like industry, job creation, and this in turn has a very high curbing away from infrastructure projects from say a town like Flint which isn't really a thriving economic center like to once was. The state itself is going to choose rightly or wrongly to dump money into places like Ann Arbor, which is much more of a thriving place in Michigan. Cities also are competing more wholly in this regard and it's unlikely Flint could even come close to paying for this being caught up with all the other services that city has to run. This is before we factor for political favors, corruption, ill fated projects and the like.
For all but the biggest metros/cities and most populous and still thriving states like California, New York, or San Fran, LA, NYC, hell your thriving and well run Minneapolis-St.Paul and the like. You have a great inability for cities and even entire States that without influx of Federal funds would be unable to do even minimal investment in infrastructure.
It's a huge problem. One of the reasons that calls for a Federal Infrastructure Investment Act is so broadly supported in both sides (though what infrastructure that would be built isn't and it is always about Roads it's seems before anything else)
