  • evento transitorio spegnimento pompa velocità variabile

    buonasera, ho riscontrato due errori in questa simulazione: 1) problema cavitazione 2) analizzando i risultati dell'analisi ho notato che le portate (flow) delle tubazioni a valle della pompa spenta non tendono mai a 0 ho pensato: per risolvere…
  • 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…
  • 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
  • Using LoadBuilder to assign customer meters to nearest pipe

    I am trying to assign demands to junctions using the LoadBuilder tool, I am using internal data through uploaded customer meter data and I have made sure that the base demand for the customer meters is filled. but after I assign the customer meters to…
  • Modelbuilder update, reallocate demand

    in WaterGems for ArcMap, I have created a modelbuilder to update pipes as a systems GIS is updated. When I do an update I am typically left with orphan nodes. What is the best way to reallocate demand on those nodes before I delete them?
  • Demand met?

    Hi. I'm new to the software so please bear with me haha. Okay now in the demand centre I have given my demands. And when I compute the results I'm having a hard time understanding if my demands are being met or not for the the junctions. Do we check…
  • Adding PRV, cant meet Demand flow gpm.

    Hi. I am new to Watergems. I have added a PRV in a layout due to which I have met my requoired pressures. But I am unable to meet the demand flow. My PRV is at a lower Elevation than the junctions where demand is not met. Please suggest. Thanks.
  • EPANET emitter

    Hi, I'm currently modelling a theoretical skeleton pipe system in an urban setting which involves some leakages at the nodes. I know the leakage equation is very similar to the equation for the velocity of water through an orifice but it's different…
  • Further potential causes of calculated demands not matching entered demands?

    This is in reference to the existing help topic " Calculated demand does not match entered demand ." The particular issue I am experiencing is as follows: there are a mix of customer meter elements with a base demand and junctions with base demands in…
  • Calibration, Validation Data Collection Standards (WaterGEMS)

    Hello all, In a recent discussion a few points came up regarding ensuring accuracy and limiting variables in SCADA and field data to be used in calibration & validation of a model. For our past clients, we have ensured that days chosen for calibration…
  • Not able to achieve the required pressure at one node in my model

    Hi guys, I am trying to Fix an issue in my water gem model for industrial area project. The model is running seamlessly perfect, But I am not able to achieve the required pressure (2.5 bar) at node point PW-12. This node connecting to the underground…
  • Doubt in Watergem node demand

    Hi Guys, I have a doubt in my water gem model. Currently, we are working in the industrial area project, So Each building has specific demand. I provided specific demand to the relative required nodes. My doubt their lot fo nodes has no demand required…
  • Peak factor and demand multiplier in WaterGEMS

    In WAterGEMS, I'm analyzing an existing water distribution system having 2 hours of water supply per day, i. e., it is case of intermittent water supply. I'm bit confused about peak factor and demand multiplier to be applied to the demand at a node and…
  • Troubleshooting fire flow analysis for private looped system with 2 new laterals to the same City main

    Hello, Myself and my firm are pretty new to WaterCAD. I have built a model with 75 elements and 81 pipes, a medium sized system for a school campus (non residential). We have two new 10" water service laterals from our private loop system that tie into…
  • Extreme Flow factors in WATERGEMS

    Hi, Water distribution scheme in my project involves supplying of water to the consumer house hold fixtures through direct booster distribution system i.e., no water tanks inside the consumer plots(all 1568 no. off G+1 Villas). My question is, if watergems…
  • This is a request, not really an ask. It would be great to be able to open a demand alternative and actually see all demands assigned, not just that there is a demand.

    It would be nice to see a companion column with all actual demands assigned, and a way to total the demands.
  • Population Input as plot areas

    Hi , I have a shape file of plot areas with number of people residing in each plot area , Is there any option to import these shape file into SewerGEMS and assign these plot area population to Manholes. Nearest node method in load builder module will…
  • WaterGems to EPAnet units conversion

    When i convert a WaterGems model to EPAnet i have no control over the conversion process. For example: My model is in m3/h. Conversion to EPAnet gives l/s and changes the demands by dividing them by factor 3.6. This means that i have to manually…
  • Why does the pressure increase with time?

    Hi. I'm a newbie at WaterGEMS and am trying to do an EPS procedure in a typical network consisting of a single reservoir, a pump, one tank, and some 37 junctions. The simulation is processed smoothly, with no alerts. The tank is never completely full…

  • Design with 3 reservoirs

    Hi I have a system as shown in the image, in the node J-3 I have a demand of 10 L / s and as you can see I get higher flows than the exit of the tubes of the reservoirs, I understand that it is due to its hydraulic gradient with respect to First reservoir…
  • WaterGems Analysis: Varying flow in pipeline

    I want to design water transmission main for upcoming development. We are proposing DI pipe of 500 mm dia. based on ultimate demand of 200l/s. However during initial phase of project, demand would be around 25l/s. For flow of 25 l/s and 200 l/s the pressure…
