Thanks guys
I should have said that the bore will be professionally drilled and the wiring all done legally, just need to lay the supply pipes myself. Needs a 42m deep bore so would have no hope of doing it myself
conduit needs to be 500mm, pvc is fine at 300mm depth most trenchers go to.
My main obstacles are a drainage pipe (which I vaguely know where is), a water main (which I know where is) and a telstra cable (which I have NFI where it goes or how deep it is). Theres a pit in the verge and the lead into the house, so I guess I will run a string between the 2 and dig down and try to find the wire.
