• WaterGEMS LoadBuilder Parameters

    Greetings, I have defined the Thiessen polygons and the water meter shapefile layers in a water model, prior to inputting them to LoadBuilder. I have also added to the water meter point feature shapefile, a new field including the demands for each…
  • Large Negative Pressure on model

    Hi, I am quite new to this software and am still in the learning process. I'd like to ask regarding a few uncertainties with my model which I believe are parts that I have missed out on. Firstly, I'd like to explain briefly on the background of the…
  • 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?

  • Simulating an existing water distribution system in waterGems and optimising it on the basis of Pattern variation.

    Hello everyone, I am trying to simulate an existing water distribution system into waterGEMS and later I wish to alter it's patterns of pumping, demand, etc.. in order to optimise it in terms of energy consumption. THE PHYSICAL NETWORK HAS BEEN CREATED…
  • Best way to duplicate waterlines and junctions for correct demand input

    I need to duplicate some pipelines and junctions in my model. The water leads connecting the waterlines to adjacent lots are only represented by one line when there should be two. Trying to input the correct demand (gpm) without just doubling the demand…
  • 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.
  • Constituent Types

    Hello, I want to know that which option is better constituent type to carry out booster chlorination study at node in Water Distribution Network? Thank You.
  • Demand Allocation

    Hi, I have a billing meter database which compromises properties with two or three kinds of consumption (e.g., residential, commercial and irrigation for an individual property). I imported these duplicate demands by individual LoadBulider run through…

  • 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…
  • Very high energy cost

    Hi , I run a water distribution system in Watergems V8i and the energy cost results are very high values. What changes could i make to my system in order to decrease the energy cost? I want to have an energy cost of 5,6 *10^6 $ for 20 years and my…
  • Re: documenting modelling process

    Platy, As a suggestion, the training manuals that are provided during the Haestad training courses are fairly robust and provide a large number of available parameter ranges, and good discussions on the expected results. I also found another good modeling…
  • Re: Fire flow on existing system

    Matt, Do you have the system completely modeled? meaning are you modeling all the way back to known boundary conditions (tanks, pumps, etc) or just a skeletal system of the model? With respect to the layount, just make sure you are modeling…

  • 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…
  • Re: modelling with 2 fire events

    Grgulla, Briefly, you mentioned it was a requirement to model 2 fire events - understood that it is a requirement - a bit conservative but I wanted to mention a few other points to consider when modeling 2 fires simultaneously- This will obviously drive…
