The standard OOTB structure labels have fields for station & offset of profile, or they can be easily added.
2009 added separate profile label styles that let them be labeled vertical below structure similar to LDD/Civil.
I just change the description field to TEE or TYPE whatever inlet to get it to label on both.
Each pipe network is set for one alignment for station & offset values. Each individual structure can be over ridden to reference different alignments if needed. 1 alignment / structure.
Getting the labels along the band as shown, follow the other posts, they are better for that.
