Drain plumbing and vent pipes

661 0
I have a barn, the upstairs of which I have upgraded to include a sink, shower and toilet. These will hook to a septic tank.

I am wondering about plumbing the drains, specifically whether or not I need to run vent pipes up to the roof.

Are such pipes needed? Can I get away without these?

Thanks
Eric
