(Eventually!) erecting a 1m high picket/palisade fence, posts 3.5ins/
90mm square. Dug 2 holes today aiming for about 24 inches deep. On the
one which the gate will hang on have got to 18inches and found what I
think is a water pipe (about 2in diameter) running across.

Question: is that deep enough to postcrete in a post bearing weight of
a gate? if so is it ok to concrete that next to a pipe?

Should be OK.

Could be a water pipe - or even a gas pipe. Is it where you would expect it
to be for serving your property and/or neighbouring properties - or could it
be redundant?

18" is probably enough but, if you're worried, can't you cut a slot in the
bottom 6" of the post to go over the pipe - or even move the post slightly
to miss the pipe?

Probably best to keep the concrete away from the pipe itself by wrapping it
in polythene sheet.

If it bothers you why don't you hang the gate on the opposite post?

But it rather depends on the width and weight of the gate, and the type
of soil. Provide those and maybe someone can give you an answer.

Flippin heck 24" in the ground for a measly 39" high fence. What are you
trying to keep out, tanks?

Seems bit big for a water pipe feeding an individual property. What colour
is it? What is it made of?

More info on size and construction of gate required.

I installed a galvanised metal gate post for one of our timber gates. The
gate is 4' x 5' timber with slats on one face. The post was 6' long but I
had to cut 6" off the bottom as I hit bedrock when digging the hole. So it
only has 18" in the ground if that. It hasn't moved in the 5 or 6 years
it's been in. When the gate is closed the far end is supported, as a gate
should be, but we do get some hefty winds up here.
