basement sink venting

[gerry_foster]

I have a question on venting a basement sink and shower setup that flow into a sanishower pump. Due to these two fixtures not being connected to a toilet, can this be vented out the wall at the floor joist height then snorkeled up the wall a foot or so? I would have to run a vent 30 feet and cut into a wall to connect to my main vent, so I am looking for a good/safe alternative to this if possible. The toilet I am using does not require a vent as it is considered a self contained macerator. (sanistar.)

Any advice would be great, Gerry
