What we use for bubble ups is an 18” N 12 pipe about 6’ long set it vertically usually some concrete mix in the bottom (maxi core)
In coming tile at the bottom out going what ever height the ditch is need an animal guard on the out put a disc blade on top for a lid
End up with the main low enough to plow over it main stays full of water
In this field laterals will probably be mostly dry when ditch is low
A cure for shallow ditches till they silt in then dig the ditch

How many years would you expect it take to silt in your 8” mains? | 
Tiling long runs at .05% check my figures
