Repair Needed: Mom's Sewer Line Collapsed

My daughter Brandi is a single mom of 3, the last year and a half has been an extremely rough she has gone through things with her job, lost her dad ( who was absolutely everything to her) and her sewer line has collapsed. After going through all this then checking with her homeowners insurance and warranty insurance that she purchased and was unfortunately told to figure it out. None of them would cover the cost to fix the collapse in the pipe because the pipes are over 50 years old. She has had no other choice but to get a porta potty for them to use. Any donations torward helping her fix her sewer line so they can simply use the bathroom in the house would be greatly appreciated.
