Sharing waste pipe/horizontal branch?

[willfaulds]

Hello,

What units can share a waste pipe. How many/what type to what diameter of pipe?

I am trying to resolve a situation where I need to add 2 sinks and 2 basins to a single soil stack. 1 of each is a considerable distance from the stack (over 6m). All will be vented will HepV0 traps. There is ample vertical room for any gradient on the horizontal branch. Ideally I would like to connect all the units into 1 branch but I can't find any advice as to the diameter of pipe required or whether it is possible. Any advice welcome.

Thank you,

Will

Is this any good to you.

Could be but that means running 4 pipes along the walls which I'd like to avoid. The sinks and basins are arranged in a way that 1 horizontal pipe run would be the most efficient but I don't know how to spec it...
