Add custom feature layer to Utility Network Solution

Question

Hello,

I created a stormwater utility network using Esri's utility network solution.  I want to add a layer of catchments that act as containers for all other features in the network.  The utility network solution doesn't have such a feature so I tried to add a custom one using the following process:

Create feature class in utility network solution asset package

add subtype and asset type field and associated domains

append my catchment data to this feature class

run "Apply Asset Package" tool (with and without checking the Post Process box)

So far this hasn't been successful.  I get various errors such as "network topology must be enabled," "network topology must be disabled", and once, a utility network without the catchments incorporated.

So, I'm hoping there is proper workflow for adding a custom feature class to an established utility network that someone may help me with.

Best,

Aaron

Thanks, Robert

I'll review the link you provided and give it a try.

@Yeaton Modeling all your catchments as network features is possible, but there is already a mechanism in place in the stormwater model for tracking catchment features using subnetworks. Most customers have their catchment layer in the same feature dataset as the utility network, for visualization purposes, but don't include it in the network.

If you do include these polygon layers in your map, then you'll need to be prepared to redraw the polygons every time an inlet is added, deleted, or moved. If you do go down this route, I wouldn't set up containment for all the features in the catchment. I'd recommend you only track the inlets (or other inflow locations) as content to the catchment, since they are the ties between the surface and underground systems. This also significantly reduces the number of associations you'll need to manage.

If you still want to do this, you'll need to add a new asset group (a subtype) and asset types to the structure boundary class to represent them. You can find an outline of how to do this in the Configure a utility network topic in the ArcGIS Online Help.

You cannot add classes to a utility network.  You would need to add these as an Asset Group and Asset Type in either the <Domain Network> Device or Junction class.
