why are you using the more expensive sch 40 pipe instead of SDR-35 bell & spigot sewer pipe? You're not dealing with any pressure and the pipe will hold up fine underground.

I was told sch40 is only good to about 14ft underground. I'm right around that so I didnt want to take any chances with the drain collapsing. The Dep wanted me to incase it in concrete for added strength.
The 10" pipe in sdr-35 was only a dollar or two less expensive. Thats why I went with it all in sdr40
