Hi,
I get this error when trying to import a point shapefile (for customer meters)
It says "Invalid Esri Shapetype"
And then "data Source is empty or contains cross referenced data"
I have view the shape file in QGIS and nothing seems out the…
I am trying to create the appropriate schema for data collection in GIS so that my client can collect water and sewer data and easily import to SewerGems/WaterGems using the model builder. Is there anywhere that lists the schema, or even just the different…
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…
I'm working in a coastal community where the terrain is very flat and therefore they don't have much gravity and they use a lot of pumping stations. They have 100's of duplex submersible pump stations and 1000's of individual grinder pumps that all pump…
We are working to calibrate a system that controls their high service pumps with VFDs at a water treatment plant based on a pressure sensor in the distribution system immediately downstream of the treatment plant. The target pressure is 50 psi. (HGL:…
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.
I have shapefiles for the model, When opened in GIS the whole model is available, and when tried building the model with shapefiles in model builder pipelines is missing. Can anyone guide me through it? I would be glad.
I am working on a model in which many of the junctions are not on the existing pipeline. So, I want to attach the existing junction(which is not attached to the pipeline) to the existing pipeline by not creating a new junction on the pipeline and splitting…
Greetings,
I am looking for a standard procedure for determining the bulk reaction rate to undertake a water quality (constituent) analysis. I understand from the AWDM book and other literature that the procedure entails sampling water from the source…
Hi there. I’m relatively new to WaterGEMS and having trouble with the automated Fire Flow analysis. I have made a network including tanks, pumps and many hydrants and I can run the Fire Flow analysis fine, getting correct answers. But I was wondering…
Hello,
I have imported a model into WaterGEMS and entered as much info as I have from the client. When I run the model, I am getting some very extreme negative pressures and hydraulic grades.
The areas of the model in question are at high points in…
Hi,
I have a situation where I have to design a gravity network such that I have to utilize the existing pipe in a given network. How to design a parallel pipe in a gravity distribution network. Suppose, the existing pipe has a dia of 100 mm and would…
Hello, I'm modelling a large size existing water supply network with many boosters through the network. There is also a tank with a pumping station through the network to provide water for a further network. So my question is how can I model a the the…
I am calibrating a system, the distribution network which has two inlets (feeder mains) on which I have flow and pressure measurement data. After simulation it is observed that one of my reservoir more push water in non supply hours and it goes to another…
It was working fine yesterday. Today when i tried to open it gives me an error.
Error Message is attached for reference. Can somebody please help me to sort-out this issue??
I would like to know why i face it and how to avoid it in future.
than…
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…
I am using WaterGEMS v8i Connect Edition\
I used to use Innovyze InfoWater for all of my hydraulic modeling needs which had the ability to copy elements from one hydraulic model, and then paste them into a different model just like any other copy/paste…
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…
Hi,
I have an issue validating this water gem file. Even I am using the latest version of water gem update 210.02.01.06 64-bit it is still showing the same error. Please let me know how to fix this error. I have uploaded the file in the below wetransfer…
I am running a criticality analysis where I perform the segmentation by computing the analysis. It works great. Next, I click on Criticality and select the "Run Hydraulic Engine" option and put minimum pressure at 30 psi. Then, when I click the compute…
Hello,
I am handling pipe network with multiple outlets which requires residual head.
However these pipe networks directly connected to 4 pumps (3w+1s).
In this case i have found starting point (i.e static head) of system resistance curve ( (Residual…
Hello,
How could I locate an isolation valve at a specific position on a pipe with a schematic drawing?
Can an isolation valve replaced by another type of valves in watergems to do the same task?
Hello,
how could I model area change in bentley hammer ?
Is there any method rather than splitting pipe? does pipe splitting do better simulation for Wave Reflection and Transmission at an expansion and a contraction?
