A dry riser is a main vertical pipe intended to distribute water to multiple levels of a building or structure as a component of the fire suppression systems. The pipe is maintained empty of water. The dry riser is the opposite of a "wet riser" or "wet standpipe" system where the pipes are kept full of water for manual or automatic fire fighting operations. Dry risers have to have fire engine access within 18m of the dry riser inlet box. (In the UK they are controlled by the Building (Minimum Standards) Regulations 2000. Dry Risers in occupied buildings have to be within a fire resistant shaft, usually one of a building's fire escape staircase enclosures.) Depending on regional nomenclature, this may refer to a standpipe, intended to provide water to hose connections, or could refer to a vertical main pipe in an automatic dry pipe fire sprinkler system.
