Dry risers are a Dry Riser Systembuilding regulations requirement in occupied buildings over 18M tall but can also be found in car parks, multilevel basements or hospital corridors where the fire service access could be limited.

A dry riser system is used by the fire services to distribute water to multiple levels of a building in an emergency. Dry risers are vertical mains fitted into staircase enclosures or other suitable positions, a static pipe with outlet valves on each floor and inlets fitted at ground level to enable the fire and rescue service to connect to the water supply and deliver water to all floors. The current standard for the installation of Dry Riser Systems is BS9990: 2015.

The dry riser external inlets need to be easy accessible by the fire service in an emergency.  The dry riser system is left dry and only charged with water when tested or in an emergency. The dry riser outlet points are positioned on the upper storeys allowing firefighters easy access to water in the event of a fire.

British Standard BS9990:2015 states  that dry riser systems should be serviced once every six months with a dry riser annual test including a hydraulic pressure test using a fire service approved hose and pump for a minimum of 15 minutes once every 12 months.
