Note:  Steady State InfoSewer solution solves for the link flow and node heads Here is an example of how the Steady State InfoSewer solution solves for the link flow and node heads or depths: •          1 ST Flow is computed in each link and d and d/D is calculated based on pipe flow and manhole loading data and not the adjusted data from the 2 nd pass. •          2 nd InfoSewer adjusts the link depth based on the manhole head and lists the adjusted depth in the browser and the Report Table after the manhole depths are calculated from downstream to upstream in the network. •          Result: The HGL graph shows the link d and d/D based on pipe flow not the adjusted depth so you are looking at the results of the 1 st pass in the links and the 2 nd Pass in the Nodes in a HGL Plot  for a Steady State Simulation. Here is one example of this sequence of event...
