What is a ‘Dry Riser’?

A ‘dry riser’ is a system of pipes and valves used to enable the Fire Services  to distribute water  to various levels of tall buildings as part of the fire suppression system.

The dry riser pipe has a connection for the fire department at ground level which is usually recessed into the outside of the building and protected in a wired glass or lockable metal box.

The fire brigade can then pump water through this external point of the dry riser  to allow the fire-fighters to connect  hoses where required on each level of the building.

A dry riser is usually required wherever there is a floor over 18 metres above ground level or in low level buildings with over 60m distance from entrances.
