Grease/Oil Trap Capacity
Grease/Oil Trap Capacity
(OP)
Hi all,
First time poster here so I apologize if I'm going about this wrong.
I've got a parking lot design where I need to determine the spacing of some grease/oil traps. For the sake of simplicity, let's say the lot is 2 acres and the capacity of the traps is 2 cfs with excess simply bypassing. We have rain totals for all storms and the main requirement is that we need to capture the first 0.5 inches of rain. How would I go about doing this? The main issue I'm having is determining if this requires a specific storm to be run or not. Obviously a 10yr, 15minute storm would produce a greater peak flow than, say a 10yr, 24hr storm.
Hopefully this question is clear enough.
Thanks

So would running a model of various storms to show which ones the selected inlets and their tributary areas could handle be the next step? I'll have to check the local ordinances but I don't think it says anything about a standard storm for determining capacity calculations.

if you have a large site then the constraint (that is, how many traps required) will be the inlet capacity and the rate at which runoff can enter the trap.
