I huge component of the reliability of the lining is in the installation. Many things could easily go wrong such as doing a lazy job making sure the subsurface is relatively smooth, or tears happening on installation and nobody speaking up about it, or people seeing it and others saying it'll be fine either because they truly believe that or because it eats into costs to replace it. Depending on the material properties, they may also be UV sensitive and stored out in the sun, decreasing it's "shelf life". This is a common issue with PVC tubing. Many people store them outside, either unaware or ignorant to the fact that it affects the integrity of the pipe.

Yes, well, if society deems it important enough, then we put safeguards in place which includes educating the installers about UV sensitivity. (you'd think the people who engineer these systems would understand the issue and put correct processes in place, no?) I mean, yeah, if people don't care, negligence will happen because no one is watching. But people apparently care, in fact that why so many people are bothering sorting their refuse, because of their fear of landfills destroying the planet.
