It's not a given that a typical ham (myself included) can achieve
consistent plumbing quality seals when working with 10' lengths of 4"
schedule 40 in deep irregular trenches and big unruly bundles of cable.
And no way to test your work.

I still don't understand the assumption that the pipe will fill with
water. Isn't that like assuming the PVC used to deliver water under
pressure will always fail and leak which flies in the face of our
experience? It doesn't leak in pressure applications over 100 PSI. A
rough rule of thumb is one PSI of hydraulic pressure for every two feet
of water depth. If your water depth plus bury depth in your back yard
is say 2 ft in total then you will have a maximum of 1 PSI of pressure.
Don't you think a system used successfully to deliver water at over
100 PSI should be able to take 1 PSI in the rigors of your subterranean
backyard situation?
