Or use SDR35 drain/sanitary pipe, available at commercial suppliers.
The strength is much higher than HD perf pipe but less than SCH40.
Available 4" and up with glued or gasketed joints (used for sanitary and
more expensive). The 4" (and maybe larger) are available perforated,
but I use solid and well glued joints for all conduits. Condensation
will occur inside but I've not seen any implementation fill with water.
Don't use sand around perf pipe, it will wash out (or into) over time.
Use drain rock 3/4 to 1".

I would like to add that some perforated drain pipes
are not very strong...might be schedule 20. If using that, be sure
to backfill equally on all sides of the pipe, leaving no voids. If
you don't, the overburden will have a tentendency to crush the
pipe over time. (All that from experience.) I like to use sand
until it's level with the top of the pipe, then sparingly wash it
in with water. Finish the backfill with whatever soil is available.
