10' C.C. Sewer

10' C.C. Sewer

10' C.C. Sewer

(OP)
I am looking at a utility plan from the early 1900s, and there is what is called out as "10' CC Sewer" shown on the plans. This "pipe" has an invert depth of greater than 50-feet. There are no structures visible anywhere on the plan sheets that I have.

Does anyone know what this could be? This is located in a major US city, and I was wondering if this is an old subway or pedestrian tunnel, but I can't find any reference of these facilities ever being located in this area.

Thanks!

RE: 10' C.C. Sewer

Conveying channel for sewerage? Or, 10' center to center distance?

Lots of options, apparently none of them good: https://acronyms.thefreedictionary.com/CC smile

In my world, "CC" almost always means center-to-center, so I like retired13's second suggestion. However, you're talking about a sewer that is more than 100 years old, so who knows.

Do you happen to know the size of the sewer? I doubt they were making 10-ft-dia sewers back then, but maybe they made a 10-ft rectangular box sewer. If this is the case, then maybe "CC" means "cast concrete".

CC means cubic centimeters, everyone knows that. 😊

I saw "cylindrical concrete" on an old sewer crawler website, so that makes some sense I guess, but no access pr maintenance structures that I can find anywhere.

may be Cement-Concrete as shown here (dated 1921 - an old terminology of ASTM ??)
