That type of building pipelines everywhere and then keeping that pipeline clean and maintained would be a very difficult thing. I am not saying that it is impossible because most of the developed world constantly has that and there isn't a situation that should be wondered "how", they just spend a quite good amount of money for that infrastructure.

But that doesn't mean that we shouldn't really expect Africans to have the same type of deal. Doesn't mean that we will have that type of thing would cost a lot for poor nations, it is not just about building, like let's say billionaires end up paying for all the pipes, that still wouldn't be kept clean and eventually be bad after a while.
