#75 Found Outside A Medical Arts Office Building In Florida. I Have Seen Pipes Like This Outside Of Buildings Before But None This Big.

Up from that is a gate valve wheel, to shut off the main, up from that is a sampling unit, presumably for testing water purity at the main, the top is another type of block-off plate, it‘s needed because the pieces are all modular and capable of having more pieces/pipes bolted to both ends.
