• Hydraulic Analysis on Agriculture Irrigation System

    I have a short agricultural irrigation system (a main) that provides water to farmers. The head of the system is a canal with a structure that provides a constant head of water elevation during the season. There is no pump to deliver water to the customers…
  • 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.
  • 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.
  • Demand multiplier

    Hello everyone. Please can someone help me explain what a demand multiplier is? I want to use ESP but I'm stucked here. I really need to know what demand multiplier is. Thank you
  • 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…
  • No Flow in tank Top inlet fill

    Hi, I have another issue in the model, If you check the T-1 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 run the same model with Max daily demand scenario (Peak factor…
  • How to model discharge to atmosphere point

    HI, I'm working on my college project (The project is a plumbing system to drain a 1-m3 tank in the shortest time ). I use the discharge to atmosphere element at the end of the project but I'm really confused with this element's input data like [Flow…
  • model output showing areas with leaks?

    Hello, I am responding to an RFP for a water distribution system evaluation which includes water modeling and calls for (among other things) "outputs from the model should include ... areas with leaks". I am not aware of a way to use WaterCAD to…

  • WaterCad Select Series 2 Copy Graph Data Problem

    I am having problems with copying data from the graph data tab. My problem is that when I copy all the data the header row is not copied. So when I paste in excel I have no idea what the data in each column represents. This woudn't be a problem if WaterCad…
  • WaterCAD for Reclaimed Water

    Any suggestions on how to model a reclaimed water system that delivers water to multiple (bulk) storage ponds? Each pond has a level control and a pressure staining valve. Is there a way to simplify this model, I can't justify trying to model all the…
  • Distribution Sytem Wide Hammer and Transient Analysis of RPZ

    I am attempting to set up a model to demonstrate how a RPZ (Reduced Pressure Principle Backflow Preventer) will respond to Hammer. For those unfamiliar with the operation of an RPZ, I have attached a document which outlines this very well. …
  • SCADA Connect Capabilities

    Hello, I am a civil/ environmental enginner working as a consultant. I am trying to find out if WaterGems is sufficient and covers all the specifications a possible client (water utility) is asking for. Can SCADA connect also collect and visualize…
  • WaterCAD age calculation fails

    I have run into a recent problem. I've been trying to do a age calculation on our water system and for some reason the largest duration I can calculate is 128 hrs. If I change it to 129 hrs the calculation fails and I get an error: Calculation Engine…
  • Initial conditions,KNOWN water level in the tank in every time step

    Regards to all. The existing water supply network belongs to III elevation zones of much larger water supply system and ends with the tank of III elevation zone. It is necessary to design new water supply network of IV elevation zone. In the…
  • Average Demand Calculation and Fire Flow

    My model is fine and everything works fine however the design criteria for demand is 2.1 multiply by the average demand + Fire Flow (as indicated in the snapshot) I have setup the Scenarios and alternative for this criteria based on the BASED DEMAND…
  • FCV Patterns

    Besides using a negative demand with a flow pattern at a junction, is there a way to model a fixed head reservoir with a downstream flow control valve and apply a specific flow pattern to the FCV? I am trying to simulate flow into a distribution system…
  • cannot control the flow stored

    Hi I am designing a water supply system of a city in which I am using 14 pumps to supply water to 6 tanks and from each tank the water is supplied to junctions. Both junctions and pumps have different patterns. I am facing following problems …

    Dear; I have potable water system which consists of pump station and one elevated tank. the pump station working 16 hours only direct pumping to the network and filling the elevated tank during this time. Then the elevated tank will feed the network…
  • WaterCad Select Series 2 Unidirectional Flushing - No Option for Pressure Constraint

    The newer version of WaterCAD Select Series 2 seems to have removed the option to specify a pressure constraint for flushing alternatives. I don't know when this was removed, but for me it would be very useful to specify a pressure constraint. The…
