  • WaterCAD UDF Flushing simulations velocity

    When running WaterCAD UDF Flushing simulations, when I isolate out a pipe section in the network, why do other pipes in the network still have flow even though there is theoretically no source?
  • Very high flow rates in a downstream pipe connecting two tanks.

    Hello , I am simulating a large area whose zones communicate through tanks. So i have 10 pipes connecting tanks. The problem i face is that the flow in these pipes cause of the altitude differences is very high, not corresponding to the demand of…
  • Reverse Flow through a PRV-5

    I am having some trouble with model. At first, I was getting an unbalanced system. I did the walkthrough on how to check and fix an unbalanced system. We updated the controls, elevations, and pump curves. Right now the Model is getting three errors…

  • How to perform gravity driven analysis in watergems?

    How to design a network based on gravity driven analysis. Basically pipe should be in partial flow.
  • Rainwater Harvesting

    We have several buildings which we are seeking to harvest rainwater to an earth dam for use. Basically we have several gutters and downpipes. The Downpipes will in turn be connected to collection pipes which eventually flow into the earth dam. The water…
  • how to find wall thickness and class of Galvanised iron pipe?

    can i find wall thickness in watergems or i have to take the help of hammer. how to design the pipe for particular grade( like mserw grades (grade a or grade b or X42)) or class (like Gallvanised iron (light , medium and heavy class) in watergems…
  • How do I CONTROL fire flow available and pressure (calculated residual) in water gems????

    It seems as if the previous designer of this residential development was able to control the fire flow available (1000 gpm) in one scenario and then control the pressure calculated residual (20 psi) in another scenario. Does anyone know how to do this…
  • Target Model Data getting deleted while importing submodel in WaterGEMS

  • How can the WaterGEMS determine pipe diameter automatically based pressure and velocity constraint on optimization by Darwin designer but i'm not having costs of pipe?

    darwin designer is asking for cost of pipe.
  • Hydrant testing as a boundary condition

    I would like to know if we could use two independent fire hydrant test (not performed at the same time) results run at two nearby locations as boundary condition to run a fire flow analysis in water model?
  • How to split crossing pipes in bulk?

    While building the model many pipes are crossing each other and I need to split them at the crossing point using junctions.
  • Potable Water Distribution Design for communities - use of PRV's

    Hi all, I have a general question on the use of PRV's at individual services for a "closed" distribution system, i.e. pumps directly draw from a treated reservoir and feed to end-users with no elevated/pressure tank and storage elsewhere. I have come…
  • Low pressure and high velocity

    Hi, I am a doing modelling for improvement of the existing system. Many location velocities are high and pressure is low. Even I tried to increase the pump capacity the pressure is not increased. Please check the model in the below following link…
  • Negative Flow in tank Top inlet fill

    I have an issue in the model, If you check the T-1 & T-3 inlet it was connected as a top inlet. When I run the simulation for avg daily demand I don't have any issue. However, when I check the properties of the tank the inlet pipe it shows negative flow…
