Find areas without water service.

AleydisG__Pere — Tue, 05 Nov 2013 13:11:42 GMT

I'm a bit lost with this as I'm relatively new using geometric networks. And right now I only have access to an ArcGIS Desktop Basic license so I cannot test anything. But still I'm trying to figure out how to do some tasks anyway.

I would like to check the areas in my water network where customers would not have water service because the mains are not connected to a well. How should I do this? Should I define my wells feature class as a source and run the Connection Checker tool? As simple as that? Would that highlight all mains not connected to a well? And what if I also want to take into account all breaks in my water netwok?

Thank you in advance.

Checking the Water Utility Network tools online help I see that the Valve Isolation Trace tool maybe would do this. Am I right?

The tool description says it "Identifies all valves on a geometric network that must be shut off to isolate a section of main." But the information about configuring the tool says "The Valve Isolation Trace tool tests whether a valve is connected to a water source."
It's a bit confusing.

It returns only valves that need to be closed. To do this, it barriers all other valves returned by a find connected trace and then traces from each valve to the water sources to make sure there is a path to it.
