Vortex Dropper Design

<<<< Apologies for the repeat post, but i think water distribution may not have been the correct place (and if i get no response here i may try stormwater next!)>>>>

I would like to design a small vortex dropper for rising main discharge to gravity network and have been battling to find any design information that will help with designing it, anyone here got some information on the hydraulics required?

Flow is less than 20 l/s and the drop would be about 2.5m but trying to reduce septicity in the system as much as possible

Look up vortex flow inserts:

Thanks bimr, that info is a bit thin for me, i need a step by step example

Looks like i need to leave it with the manufacturers

Most people just install an insert into a manhole.

If you want to design the thing, look here:
