Could I make a couple of suggestions.

Don't change nyms from one part of a thread to another, nobody will know
that you are the OP.

Answer some of the questions and provide more information. You haven't
said where the water is coming from or how much you need at the destination.
You haven't given us enough to make a guess if 1" polypipe will in fact be
adequate. You don't want to go to the trouble of buying and laying the pipe
to discover that it doesn't work.

If the inlet pressure is not very high 1" may be too narrow to give the
outlet flow you want, if it is going up hill you might get a tiny flow at
the outlet or none at all. Also 1" has a tendency to kink and get flattened
very easily. If using 1" DON'T use push fittings (bayonet fittings) they
will pop off all the time if put under pressure, use the more expensive
fittings that clamp the pipe with a nut.

A knowledgeable irrigation equipment supplier will be able to advise you
correctly, whether such is available near you is another issue.
