concrete cast around PVC

I have a section of the top of a retaining wall where I will have some
PVC pipe penetrations (perp to the wall) of various types. This
section of the wall has no real load on it. The only stress on the PVC
will be the pressure of about a foot of concrete. Do I need to specify
a minimum thickness of PVC or some type of CIP sleeve? There will
hardly be any other plumbing on this job in regards to special
ordering something. Worse case pipe is 3" "regular drain pipe", don't
have any specs right in front of me, this is for rainwater deck
drainage.

I have no issues with the wall, just making sure I am OK with the
pipe.. The wall is actually existing except for the top where we are
placing a repair section up to 2ft tall.

Thanks in advance,
