Modeling StormTech Chamber Outlet Pipe

Modeling StormTech Chamber Outlet Pipe

Modeling StormTech Chamber Outlet Pipe

(OP)
I'm using a StormTech chamber system for a stormwater detention system. My outlet pipe is connected at a chamber end cap. The question I have is, what is the best way to model the outlet in HydroCAD?

RE: Modeling StormTech Chamber Outlet Pipe

WHAT ARE THE inflow parameters?
precip, intensity, Tc, area, C,
size of system (Storage capacity)  size and type of outlet?

diameter, length, elevations of storage tank, invert elevation?

Cap07,

Just add a culvert outlet to your underground pond.

Thanks Peter, I'll give that a try.

Hi Peter,
I used the culvert and ran some numbers - it looks good.  Thanks again for your help, I really appreciate it.

I also put a culvert for my outlet device and it works great, but how can I slow the outlet rate down.

Hi smk2,

I think you'll need to define an outlet control structure.  This article on the HydroCAD site helped me with my design:

You could put an orifice plate over the culvert inlet: Assuming that device #1 is the culvert outlet, define the orifice as device #2, and set the orifice routing to Device #1.

See previous post for further details and illustrations.
