Big Green: geo-exchange

[Pavlova, Ludmilla]

I like that term as well!  This conversation reminded me to ask you
this: has anyone studied the implementation of geo-exchange systems that
are implemented in parallel with domestic septic systems?  Is there a
synergy between the installation of a leaching field and the possible
concurrent installation of geo-exchange piping?

Just wondering...
