EPS modelling for the new system design

Hello Hamid,

I'm not sure I completely understand the question, however while automated design doesn't work with an EPS run, you can design the gravity portion of the model in a steady state scenario first, if you wish. Pressure systems cannot be designed with automated design; only gravity networks will work with that. Catchments, pumps, wet wells, and pressure pipes (and the elevations related to these) need to be added manually, but you may have this data already, particularly if this is a real system. Once you have some data, you can enter the rest of the data you have (or estimate it based on your engineering judgment) to complete the system.

Otherwise, you will need to use trial-and-error and your engineering judgment to design the system. Infomation for the gravity system will require this as well, but if you have some idea of the general elevation and size information for the gravity and pressure subnetworks, that will at least give you a good starting point.

If that doesn't help, please give a thorough description of what exactly you are trying to do and what data you do have already.

Regards,
Scott

Hi Scott

see the following captured,

I just have the manholes ground elevation and catchment and pump specification.

if you are going to design this from the beginning, what procedure you will use?

Thanks

Hamid

Hello Hamid,

I would recommend looking at Section 10.7 of the Wastewater Collection System Modeling and Design book offered by Bentley (www.bentley.com/.../WCSM.htm). There you can find information on modeling design systems like this.

As mentioned, the exact process you can use will be up to you. However, you can start by entering the data you have and running an automated design in a steady state run to get a starting point for the system. You can then switch to EPS and fine tune the design of the system manually. Other methods are certainly viable, including simply using EPS and using trial-and-error, and other engineers here may have processes for designing systems like this that have worked in the past.
