Colin,
In rainy old England, they use a large amount of polypropylene pipe for gas
and water mains.  The stuff I saw lying beside the trenches last summer was
6" or more in diameter, and is probably fairly non-conductive (judging from
the comments about static charging from the workers).  I've seen bright
purple, yellow, and a blue version.
