The InfoSWMM Facility Manager offers the knowledgeable engineer complete control what elements are simulated in her or his model. You can make active or inactivate elements based the type of Network Element, A Network Path, A Mouse Drawn Map Selection, The Domain, A selection set, a DB Query, a Query
Subject: InfoSWMM and H2Map SWMM Selection Set and Domain Manager
You can use the Domain to easily make selection sets using these two steps. You make a Domain which is the areas of the network you are interested in at the current time and then save your Domain of Interest
Subject: Pump Volume per Pump Event in SWMM 5
You can calculate the volume per startup event by using the Pump Summary Table in SWMM 5 and copying a few columns to Excel.
1. Go to the Pump Summary
2. Copy Pump Name, Total Volume and Pump Startups to Excel… Read the rest
Subject: How is the Volume Calculated in the SWMM 5 Groundwater Component?
The groundwater component of SWMM 5 is found in the gwater.c code. It (as is all of SWMM 5) is excellently written in small functions by Lew Rossman of the EPA during the SWMM 5 development process. … Read the rest
Subject: Hierarchy of Your Network in InfoSWMM and H2OMAP SWMM
In both InfoSWMM and H2OMAP SWMM you can run a subset of the network by using the Facility Manager to make part of thenetwork inactive and not solved. You can make the output files smaller if you are performing … Read the rest
Subject: Import of Sections from SWMM 5 into InfoSWMM and H2oMAP SWMM
A very useful hidden feature of the import SWMM 5 to InfoSWMM and H2OMAP SWMM is the ability to import all of the data or just one section. For example, you can import the LID data, DWF patterns, … Read the rest

Note: Node Comparison in InfoSWMM and InfoSewer
1) Is there an option to set the manhole sealing method (i.e. locked
or unlocked) in InfoSWMM? You set the Surcharged depth to a positive value to prevent flooding and keep the pipes under pressure. You will still have flooding once the … Read the rest
