Is it as simple as "no money and no political will to pay for it"? Or are there some "economic drivers" to maintain the status quo?
Like, for example, what I saw happening in Montreal with their water main pipe replacement circa 2010. They were digging out rusted-out steel water main pipes. For the duration of the replacement, they created a bypass water line using the modern day plastic pipes, the same green ones you see used everywhere else, because you put them in and forget about them, because they won't degrade over time or rust. But not in Montreal, oh no! That would have been too forward-thinking and pragmatic. So while the plastic pipe temporary bypass was in place above ground, what they were burying back underground was: brand new steel pipes, same as the ones they just dug out. Why? Well, because there was not one, but two steel pipe manufacturing plants in Quebec. So, you know, "economic drivers" of the situation supported "domestic investments". Bla-bla-bla.
Meanwhile, the color of the tap water on the island of Montréal remained a suspicious shade of brown ochre and left you with a subtle rusty metallic aftertaste. Who knows why?
