Ross,

A cold water pipe can be used for a small coil.  I would say up to 15 kv at 
60 ma.  Be sure to connect to the pipe just before it goes into the ground.  
This would be the cold water feed line coming into the house.  Be advised 
that some problems may result.  When my small coil is running, using a 12 kv 
60 ma transformer, I can draw sparks off the two copper ground rods!  This 
means someone in the house may be able to draw sparks off of a kitchen 
faucet.  You may also experience problems with unwanted RF noise feeding back 
into the house mains since the breaker box is grounded to the cold water 
line.  I have heard several folks say they use the water pipe for small 
coils, I still prefer separate ground rods.
