That’s not true.


Telecommunications manholes are square / rectangular.

Stormwater and Sewer are usually round.

@scorpiolovedeep True... But you're overlooking that comms manholes are not in streets where cars drive ....

The question doesn’t state where..
I just replied to the question.

In saying that , I saw a couple in Brisbane.

I will try to take a photo next time if I see them.
