How can I model a pumped pond with the Implicit or Explicit (SWMM) dynamic solver? (a pond that is drained with a pump instead of a pond outlet)
A pump is connected to a pond by way of a pond outlet node element with a pressure pipe between it, as seen in the figures below. Select your pond from the "upstream pond" field in the pond outlet node and choose "false" for "has control structure".
Pond > pond outlet node > pressure pipe > pump > pressure pipe
Single pump:
Pump Station (multiple ponds in parallel, associated with a pump station element for organizational purposes):
Note: if you encounter problems with pump results (especially when manifolded), try setting the pressure pipe between the pond outlet and the pump to be a virtual pipe (Is Virtual = True).
How are pumps handled in each Haestad product?
