  Product(s): CivilStorm, SewerGEMS
  Version:  CONNECT Edition, V8i
  Area: Layout and Data Input


What is the workflow to model treatment for pollutants in nodes and ponds using the Explicit solver in SewerGEMS and CivilStorm

Problem 31515


For this type of analysis, you would need to use EPA-SWMM features, so the solver needs to be set to Explicit (SWMM) in the calculation options.(Analysis>Calculation Options)

In the properties of the pond or node, find the section SWMM Extended Data. Find the property field Apply Treatment and set this to True. Then click in the Treatment Collection to open a new dialog. The Treatment Collection will include the pollutant and a treatment expression. For more information on the treatment expression and how this is formatted, see the Help documentation related to treatment. The EPA-SWMM user manual will have additional information as well.
