I just read the short article, so the actual 600 page report might actually make sense. I'm quite surprised they just went with wire breaks instead of endemic corrosion. Also, they forget that these wires are wrapped, so that one break can affect several loops. Also, corrosion softens the wires, and there are more cracks.
The slant of the report is towards just locating and fixing wirebreaks. And then eveything is hunky-dory.
This would give the wirebreak people lots of fine work. In reality, the entire pipe is rotten, and on the verge of more breaks. There will be on an exponential increase of whack-a-mole on fixing the detected breaks. I also suspect the 'error bounds' of detection make everything an academic exercise.
Honestly, I don't live there, and I think everyone there is as thick as a board. That doesn't mean much, because I think everybody is the same. I just like to write to think out loud, and expunge the whole thing from my head.
I see them wasting endless money on fixing, and then replacing the whole thing in a few years. Maybe they could just say this, and start on a new one. The same cause in Ontario has us replacing all the bridges. I'm wondering if a concrete pipe with epoxy-coated wires is good.
As stated, the rational statement would be that all such pipes are a hopeless cause, and we are starting emergency replacement of all such watermains. It's better than making a rather hopeless "Silicoal Valley".
