I had my residential waste pipe lined with a fibreglass/resin sheath about a year ago. Inserting it was a process involving a lot of work on endoscopes and then the liner itself was adhered to the old pipe using a bladder filled with hot water. See: https://en.m.wikipedia.org/wiki/Cured-in-place_pipe

It was over CA$10k to get it done, but the cost of trenching that line could have been 3-4x the amount + an unacceptable risk to the foundation of the house from destabilizing the dirt around it.
