Unlike in previous releases where Storm and Sanitary Analysis was available as a Subscription Center "Product Enhancement", the 2013 SSA release is now included in the AutoCAD Civil 3D software (take a look at the hyperlinked features tab for more info).
Please accept as a solution if this fully answers your question, or reply to this posting if I can be of further assistance.
I should have updated my post. My tech support finally got back with me 2 hours ago and directed me to the slide menu on the installation I wasn't aware of when I installed initially. Now I wonder what else I missed. Will have to go back and look around.
Thanks for replying though.
