Sink waste to underground drainage?

[flanagaj]

when connecting an internal sink waste to soil pipe, do you have to have a bottle gulley outside or can it simply connect to a sweeping 90 degree bend out through the building and then connect to the main soil pipe with Y joint?  I am anticipating someone telling me that even though it's only a sink that feeds that section, it still needs to be rodable.

 

As we have an ACO drain running around the perimeter, the bottle gulley won't work as it will be pushed further out from the house.

It's supposed to be rodable outside, or inside, if solids are present (food waste), but if this is a basin, then you can likely get a deviation from the BCO (if there's one to pacify?).

It's a kitchen sink, so I guess that will be deemed food waste.  Looks like I'll have to have another IC on the drainage run.
