I am trying to assign unique ID numbers to catch basins. Ideally the numbers would be somewhat in sequence as one travels along the drain pipes from the outlet.

Can someone suggest a workflow, tool, or a python script that might help me accomplish my goal?  I find the idea of doing this manually for thousands of catch basins abhorrent.  I would welcome any suggestions.
