Not enough flow for a depressed siphon
Not enough flow for a depressed siphon
(OP)
Correct me if I'm wrong here.
I have to check the possibility to use a depressed siphon to get to a Sewage treatment plan. The inflow is 2 x 8 inches pipe and combined they give a PDWF of 0.5 cfs.
The Siphon should be a 8 inches pipe (or...force to a 6 inches).
Under the PDWF, the velocity is only 1.3 cfs (well under 3 cfs).
Plus, the PDWF is associated to a future development...
Need more flow?

RE: Not enough flow for a depressed siphon
Peak Daily Wet Flow is 1/2 cfs.
Not enough flow rate to ensure a 3 cfs in the siphon.
I'd need a 5 inches pipe for so.
