I am running SewerGEMS Sanitary V8i in ArcMap. I have a system of nearly 2000 conduits and manholes only. Right now, I have no physical data in the model, but I would like to generate manhole invert elevations for the entire system based on one elevation at the lowest point of the system and a constanst slope of 0.005 ft/ft up to the ends of all the branches within the system.
I want to do this so I can have a simple working model before I begin to enter actual manhole invert elevations individually.
Thanks.
Jason,
You can do this with SewerGEMS Sanitary's automated design feature. I would recommend reading the help documentation on this feature as well as going through quick start lesson 2.
Here's a basic summary of what you'll likely be doing:
1) Enter slope constraints in the design alternative as well as cover, velocity, etc.
2) Enter possible conduit section sizes in the conduit catalog and make them available for design
3) Set all conduits to catalog conduit with the same section shape and material
4) Enter the one known elevation for the low point of the system (probably your outfall node) and choose "false" for "design structure elevation". This way, the elevation will not be changed during automated design, and all other structures
5) Choose design mode in your calculation options, then compute
If you have any further questions, please contact support.
Regards,
Jesse
Edit: Good points Tom, on the ground elevation and inferencing tool.
