What is a dry riser?​

A dry riser system is an empty pipe running up the inside of a building which can be connected to by firefighters and used as a pressurised water system. There will be inlet connections on the outside of the building – or in fire escape areas – for the fire services to access, allowing the water to be pumped up to valves on upper floors on the inside.

Surely this didn't warrant a dedicated thread. Seems more in line with "Strange British Things" or perhaps "things craner will love"

i think you have dry risers in America

Can you also dispel the second suggestion?
