I'm planning on running a new sewer line myself. Is 4" schedule 40
sufficient for sewer line when it's buried to a depth of 10-12ft? What
about coupling the pieces of pipe together? Are glued couplers
sufficient,
or should the joints have rubber sleeves over them in addition to glued
couplers?

TIA,

Where I live they use 4 inch ABS for sewer lines. You had better check with
your local requirements before you dig. Primer and glue.

10-12 feet deep is really down there. You will need to open the trench at ~
8 feet wide to get that deep. (Osha trenching requirements)

Have you verified that the sewer tap is actually that deep?
