Hello,
I want to set up components of a pump station (inlet well, Coarse Screen chamber, wet well etc) in SewerGEMS. Can any one advise the most appropriate way to do it.?
Thank you
Nishadi

As a follow up to Tom's reply:
If the headloss through the component can be reasonably simulated with the standard orifice or weir equations, you can select "true" for "Has Start Control Structure?" or "Has Stop Control Structure" in the properties of the conduit, then define the properties of the control structure.
If you can model the component with the standard headloss equation in a pressure pipe, use the "Minor Loss Coefficient" field in the pressure pipe properties.
As a side note, one consideration when using control structures in the numerical solver. If the default Implicit dynamic wave solver has difficulty converging with these control structures in place and you cannot simplify them into a single structure (or neglect them), consider using the GVF Convex solver. (see Conduit Control Structure section of this article). There are other differences to consider (you can read about some of them in this article) but conduit control structure and pressure pipe minor losses tend to be more stable.
Lastly, here is another article with general information about modeling things that may not have an explicit element type.
