How to Make Break Nodes in #INFOSWMM and #H2OMAP SWMM

How to Make Break Nodes in #INFOSWMM and #H2OMAP SWMM

You would add a break node to break up long force mains so that the pipe(s) react faster to the pump flows.

  1. Find your long FM or long  Gravity Main links
  2. Insert a Node into the middle of the link to break the link into two links with the same geometry but different lengths
  3. Use the Node Inference tool to estimate the new nodes invert based on the immediate upstream and downstream node inverts
  4.  If you make a new for a FM, please also use this tool  
which will set the Surcharge depth – 1000 is bit high
