It's important to understand that the mechanism at work here is 
RADIATION. The wiring in HIS house is a TRANSMITTING ANTENNA, and that 
is the primary mechanism by which you are hearing the trash, which your 
receives like any other RF signal.  The only part that CONDUCTION plays 
here is that the trash gets onto that wiring to radiate.  The wiring in 
YOUR house is NOT part of the problem, and there's nothing you can do in 
YOUR home to fix it.

Like most noise sources, you've got to get a stake through the heart of 
the beast itself.  From the description, it sounds like a classic BPL 
sort of transmission system, and it's unlikely that it can be "fixed" 
without unplugging it.
