EPANET Tutorial | How to design a Looped Water Supply Network with EPANET Software

EPANET One-to-One Training Course Announcement: • Announcement: EPANET O...
In this EPANET tutorial, we are going to learn how to perform hydraulic modeling for a LOOPED WATER SUPPLY NETWORK using EPANET Software!
EPANET is one of the best hydraulic modeling software especially when it comes to designing water supply projects and as Civil/ Water Supply engineers having at least a basic knowledge on how to use EPANET Software is very important!
This video was originally recorded by @isaac wait and I thought there are a few things I could add! And that being said, we are going to cover:
1. How to model a water supply network.
2. How to optimize a water network model.
3. How to How to check network sustainability/reliability using extended period simulation.
Basically, we will cover all basic principles on how to model a water supply network with EPANET Software!
It’s a 30+ minutes tutorial so I really encourage you to watch it until the end!
And if you are interested in GIS or Water Supply related content please subscribe and share with your fellow engineers!

Great video -- thank you!

[@HydroinformaticsAcademy]

Thanks Mr Isaac! By the way also thanks for your content really helped me and I am still learning from you!

The tutorial is really helpful. Thank you

[@HydroinformaticsAcademy]

Thank you brian, I am glad that it was helpful🙏

[@user-uy3kz6ol6m]

Interested lecture thank and much appreciated for the explaining of EPANET software.

[@HydroinformaticsAcademy]

Thanks alot🙏

[@azadmir8871]

Thank you very much for you video, can you explain us how we can add a "fire pipe" in network

[@HydroinformaticsAcademy]

I think the best way is to identify fire pipe outlet location/junction then you need calculated fire demand and if you have it then after you identified the location/junction what you need to do is to assign it and proceed with running your model!

[@youssefmouacha3296]

Thank you very much for you video, can you explain us how we can add a "fire pipe" in network ? all of time for example, one fire pipe must product 60m3/h with minimum one bar ! Thank's a lot

[@HydroinformaticsAcademy]

That can be done, in my opinion, what you can do (when you design your network) is to introduce a node with a base demand equal to 60m3/hr (16.67L/s) and then adjust the whole network to make sure its capable of supplying fire flow demand of 60m3/hr and at that added node make sure pressure is 1bar (10mwc)!
And if possible you can even go further by performing Extended period simulation just to make sure your network is well optimized to handle demand fluctuations!
In fact, in the future, we may have some tutorials related to fire flow demand... just make sure you subscribe to be notified when we upload new videos!

[@youssefmouacha3296]

@@HydroinformaticsAcademy thank you for your answer, it's like what i tried to do (flow demand increased to 17l/s) and i make my demande in two hours (new pattern). Also the elevation of the node is increased by 10m (like to create the pression 1bar) ! is this method correct ?
waiting you nexts videos,
regards

[@HydroinformaticsAcademy]

@@youssefmouacha3296 Adding a separate pattern for Fire flow demand is correct, but the *idea of increasing node (with* fire flow demand) elevation is good because let's say your actual ground elevation (at a node with fire flow demand) is 100m and in epanet you assign its elevation with 110m (and not 100m actual elevation) this alone is going to guarantee you that at that node (after assigning additional 10m) is going to get 10mwc/1Bar!
And if you run your model and you get any +ve pressure value at that node then the actual result is going to be 10m plus that value you got after running your model!
Let's say your node elevation is 110m (after increasing it with 10m) and after running your model you get 6m as pressure! so the actual pressure at that node is going to be 10mwc + 6mwc = 16mwc = 1.6Bar! ....
But IMO that is kinda tricky especially when someone is going to work with your model in the future!
BUT to keep things simple you can try what I told you earlier! by first maintain the actual elevation (say, 100m) and then assign a node with fire flow demand then adjust your system/model to make sure a node with fire flow demand is actually getting 17LPS and pressure is not less than 1Bar/10mwc!
Which at the end you will probably going to get the same result!
All in all, it's the correct approach if and only if after adding 10m (on the node with demand flow) you get 17LPS and any +ve pressure value!

Great video, Sir! It helped me a lot in my college final design project. I have a question, though. How do I distribute the base demand throughout the whole community when I am only given the total demand at that certain location?

[@HydroinformaticsAcademy]

Thanks and welcome! Is it a looped network? or dead end like the one on tutorial?

[@nof2287]

@@HydroinformaticsAcademy I need to do both and choose which is a more economical design. Really hoping for a reply. Thank you, sir!

[@HydroinformaticsAcademy]

@@nof2287 For looped network what you need to do is to distribute or to divide your total demand on each node or at least corner nodes i.e. if your have 8L/s as a total demand and you have a total of 8 nodes in a loop then take 8l/s/8=1L/s for that, you need to assign 1L/s on each nodes in the loop!
For dead end its straign forward, if on a given end point you have say 0.8L/s as calculated demand then that is something you need to assign on such a particular point/node!
NB: Depending on which analysis you opt to run (staedy state or EPS) You need to be aware of base or average demand vs actual demand which includes the multipliers!

[@nof2287]

@@HydroinformaticsAcademy I am planning to perform EPS! This really helped a lot since I was stuck at adding base demand for days! Thanks a lot, sir! I'll surely recommend this channel!

[@HydroinformaticsAcademy]

Very good, Just be aware that for EPS you need to use average demands without hourly factors. You also need to set the appropriate multipliers and assign them on each node with average demands. Then after that, EPANET will run eps to get the actual demands which includes multipliers that you assign on the nodes!
Once again, thanks alot and I wish you all the best in your project🙏
