Gullies connected to manhole

[walaa4]

Hi everyone,
I'm working in stormwater network design and I want to confirm the maximum number of gullies allowed to be connected to one stormwater manhole as per British Standards?

Thanx

I would recommend contacting your local reviewing agency or review local design standards.

Just for interest, not sure what a "gullies" is, could you provide some additional clarification?
