Outlet Routing
Outlet Routing
(OP)
Hello,
I want to make sure that I am routing the outlets for my stormwater storage chambers correctly. The chambers are to be designed to outlet to a manhole with a weir. The outlet from the chambers will be a 6" pipe which connects to the weir manhole. In the weir manhole, there will be a 4' wide, 12" tall weir (10" breadth), and the outlet from this manhole will be a 15" pipe. The routing is currently setup as follows:
15" culvert - Primary
Broad-Crested Rectangular Weir - Device 1
6" Culvert - Device 1
Thanks

RE: Outlet Routing
If the 6" pipe discharges THROUGH the weir wall,only then would it route to Device 1 directly.
RE: Outlet Routing
Device #1 = 15" culvert - Routing=Primary
Device #2 = Broad-Crested Rectangular Weir - Routing=Device 1
Device #3 = 6" Culvert - Routing = Device 1
This format provides a better explanation of the device routing. Devices 2 and 3 are both routed to device #1, the culvert, which is the final (primary) discharge from the pond.
