PLEASE NOTE: Static Water Level for Submissible Pump = Max Drawdown Level (NOT PUMPSET LEVEL) - Destination Point Level
In this EPANET Tutorial, we are going to see how to size/model water pumps using EPANET software! Not only that, we will learn how to design a rising main pipe and we will compare two design cases and see which one suits our needs the most!
That being said, In this EPANET tutorial, we are going to learn:
1. How to design a rising main pipe with EPANET 2.2!
2. How to prepare data for EPANET Software
3. How to add pumps and pump curves to EPANET Software
4. How to optimize our model
5. How to select the most suitable design
6. How to produce a full report for your project.
I tried to cover basic principles on how to model water pumps with EPANET!
It’s a 27 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!

Good,, hope after completing epanet course... You will go for Watergems
That's for sure! Infact i started with epanet because i believe its the foundation of other modeling software! So rest be assured that the next stop is going to be WaterGEMS!!
Sir, how can we know that the Borehole Capacity is 1.4125L/s? Thank you
May I get the full tutorial of design pump bases on we already have pipe lines which are exporting from google earth .
Actually I was about to cover that before the last tutorial i uploaded few days back (UTM data from google earth)! I will cover that one sometime in the future...🙏
I see that you're using internal diameters for your lines. Does it mean that one has to be familiar with the pipes available on the market and their corresponding internal diameters?
Absolutely!
Otherwise you might endup with wrong results!
Hi sir, do you still need to add pump curve if you input values in power in pump?
It is not necessary because if we needed to use curves for calculation then we'd need it but for as long as we used power then there is no need!
When calculating the total riser tank elevation where/how did you get the 6m?
is the 6m the tank stand height?
Its been a while but as far as I can remenber that was riser tank stand/columns/ground to bottom slab height!
Absolutely!
I think a piece of data missed either the well static water level & drawdown or the Dynamic water level from the pumping test report. and I think the aquifer elevation should be the level of the dynamic water level instead of the level of the pump set because the static head = Water level at the riser tank - Dynamic water level at the well. What do you think? Please clarify.
You are very right and agree with you it was a mistake! The static head for any submersible pump should be estimated from the Maximum drawdown point and not where the pump is installed!
I don't remember well but I think I clarified it in the other pump tutorial!
I will find a way to notify people about it either by writing about it in that video itself or writing it in the description box so that people can be aware of it!!
Thank you so much for pointing it out and for the feedback as well🙏🙏
@@HydroinformaticsAcademy is it in this timestamp 12:47 ? What data should then be changed?
@@rcane6842 YES! the elevation data you need to insert at this timestamp is not elevation data on where the pump is installed but rather where the maximum drawdown point is located! so if elevation at pump intake is 1111m and elevation at max drawdown is 1130m then use 1130m! somewhere in the future, I will possibly create a tutorial to explain this issue!
Hellow engineer, I have the problem and I don’t know how to solve it. I try to run the system on epanet and I insert the flow of 3 .25 l/s on pump curve with the head of 135 every thing is oky bt the problem the flow on links and nodes it show that 0.00
And the setting on epanet is l/s
If you did not get any error after running your model then Check the units format that you are using and make sure the epanet is set to use the same settings! If you are using L/s then make sure you set L/s on epanet as well.
NB: Check if you are running EPS as well, it might be your model is running at an hour with zero demand.
Can you please insert the .inp file here so we can practice while watching the video ?
It has been a while since i created this tutorial but if necessary I will do that for future tutorials🙏
Hello, I try to work network like yours, but the flow in my network shows negative values, What does it mean ??, distance is about 10km from the source to tank
the topography has some hills along the way. source point at this elevation 1126.4m while the tank at 1186.6m Any explanation
Speaking of negative flow, do this...
Right-Click "link/pipe" with the negative flow then click "reverse" then run your model again by clicking "run"! I hope it will be resolved!
You can as well watch this tutorial: ruclips.net/video/2YDpuUtuNdY/видео.html
@@HydroinformaticsAcademy Thank you, but Any explanation you can give that why that happens ?? I reversed and it worked
I think its because you drew pipe/link in the direction which is opposite to the direction in which water flows.
