  • hydraulic time step for SewerCAD.

    Hello, I have a question on setting correct time step in SewerCAD. I am modeling a big wastewater collection system with 200+ submersible pump stations. Pump station is turned on and off by the water level inside the wet well. To get a quicker simulation…

  • Insert pressure junctions at regular intervals

    Hi, I'm currently working a 12km long pressure pipeline where i would like to insert pressure junctions at regular intervals (every 50m) to enable ground level to be referenced along the pipeline. Is they a tool avaliable to automatically insert these…

  • Modeling Jockey and Main Fire Pump

    We have a client request to run a surge model to check impact of electrical pump startup on the fire network. The operation of this network is different from standard. The jockey pumps are selected for a flow of 60m3/hr at a head of 35m, while the main…

  • Modeling pump trip and then re-start

    Hi, I want to model pump trip and then re-start to check the pressure (over or under) in the pipeline system for this condition. I have gone through some available help and understood steps as below: 1.) Change pump type (transient) to Pump Start…

  • Negative pressure

    Hi, I'm trying to solve the negative pressures in my model. I read the trouble shooting article (Troubleshooting air valves at high points with the GVF convex SewerCAD solver) and followed the steps, runng a steady state first with all air valves off…

  • SewerCAD - Pump Report

    Hello, I am trying to generate a report on every pump in my model. I need the report to display the number of times a pump turns OFF and ON. Currently my reports only display the status of the pumps at a single moment in the hydraulic time step. How…

  • SewerCAD - pressure pipe branches

    Hi, I have constructed a sewer pressure main. As i add pressure pipe branches into this main the main is broken up (split) into smaller pipe sections. Is there a way to add branches into a pressure main without splitting? Thanks Matt

  • SewerCAD Peak Factor

    how can I present the peak flow " Extreme Flow" calculated (the value at that particular location) in the output report "Flex Table" ? I guess we should be able to find out what is the calculated and multiplied value. The client always asking about…
