Hi Jacques-Louis, standards for potable water age are likely different for each geographic region and local reviewer. If you submit to a reviewing agency, you may want to check with them or with any local standards. You can find additional guidance in our Advanced Water book: store.bentley.com/en/products/books/9781934493014--Advanced-Water-Distribution-Modeling-and-Management For additional questions about the software itself, post on our forum: communities.bentley.com/products/hydraulics___hydrology/f/haestad-hydraulics-and-hydrology-forum

I have a as built drawing map for water distribution network in tow districts with table of pipes diameter who can i start drawing in watercad this network I have many questions like where the junction place and direction of flow
If you are not sure where to start, I recommend watching the fundamentals training course (see link in homepage of this channel). If you have a CAD drawing of the network, save it to DXF format then use ModelBuilder to import into WaterCAD or WaterGEMS to create the pipes as seen in the article below. For further assistance, please post your specific question on our forum (second link below) communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/3070/importing-an-autocad-or-microstation-cad-file-using-modelbuilder communities.bentley.com/products/hydraulics___hydrology/f/haestad-hydraulics-and-hydrology-forum
The water age shown at an element represents how long that water has been in the system (since it entered via a reservoir or inflow) at the current timestep. So for example if you're looking at timestep 18 hours and a tank shows a water age of 18 hours, it means that the water in the tank has been in the system since the simulation began, and if the water age at a demand node at timestep 18 hours shows a water age of 1 hour, it means that it took one hour for the water to travel from the source reservoir to that demand/outflow point.

thank you for your excellent video!! is it possible to simulate contamination spread with this tool, by define an injection in a random junction so the model will calculates the contamination area and show's the pipes who got infected?
Liron, yes, you could use either a trace or a constituent analysis for that. If the contamination starts at a reservoir, the trace analysis would show you the percentage of water at certain points in the network, that came from the contaminated source. For a "random" junction, you could use a constituent analysis and color code the calculated concentration to see it spread.
thanks alot can i ask in the constiuent basein the junction there is concentration base and intial whats the defrence what are the values i should set thanks alot
Hello Rureta, the "Concentration (Initial)" is used to define the concentration at that node, at the start of the simulation. If you leave it as the default of zero, then the concentration will be initially zero and the model will take some amount of time to reach an equilibrium point. The initial concentration would be useful if you had the ending concentration from another EPS run. On the other hand, the "Concentration (base)" represents an input of a constituent - meaning, an injection of the concentration at that point in the network. If your constituent enters the system at another point such a reservoir or tank, then leave the junction base concentration as zero. See: communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/16546/understanding-constituent-source-types-and-constituent-patterns For future questions, you can post on our active forum: communities.bentley.com/products/hydraulics___hydrology/f/haestad-hydraulics-and-hydrology-forum
Hello LaxmaReddy, water quality calibration in WaterCAD and WaterGEMS is a manual operation at this time. You can use the constituent analysis and compare results to field measurements, adjust and repeat. See the note about calibration in the following article: communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/31934/getting-data-and-setting-up-for-a-constituent-analysis-in-watergems-and-watercad See also: communities.bentley.com/products/hydraulics___hydrology/f/haestad-hydraulics-and-hydrology-forum/183132/water-quality-calibration/
Hi Rureta, it is best to post your question on our forum here: communities.bentley.com/products/hydraulics___hydrology/f/haestad-hydraulics-and-hydrology-forum
Hello, there is a "variable area" option in the "section" field in the tank properties, which enables you to model irregular-shaped tanks.

great video
thanks for the video :)
What should be the maximum water age allowed in a drinking water system? Does Bentley have any rough recommendations please?

thanks a lot
My background map size is very less...when I use pipe function ...it's very big than background map...how can I overcome on my problem.?

What do you mean by water age ? How could you measure it along the water network?
The water age shown at an element represents how long that water has been in the system (since it entered via a reservoir or inflow) at the current timestep. So for example if you're looking at timestep 18 hours and a tank shows a water age of 18 hours, it means that the water in the tank has been in the system since the simulation began, and if the water age at a demand node at timestep 18 hours shows a water age of 1 hour, it means that it took one hour for the water to travel from the source reservoir to that demand/outflow point.

waw that is amazing
thanks alot
can i ask
in the constiuent basein the junction there is
concentration base and intial
whats the defrence
what are the values i should set

I hope you can answer me
in darwen designer
can I put as a condetion that all the pipes in the same street take the same diameter
if its possible please could u explan it??
