Dry Risers are an essential part of any building design where the height of the building exceeds 18 metres from the fire brigade access level to the top floor. They are also required where there are floors more than 10 metres below ground.
The firefighters fill the dry riser pipe with pressurised water by connecting the fire engine hose to the inlet on the ground floor. They can then connect hoses directly to the lifesaving water supply on the floor nearest to the fire using the outlet valves connected to the dry riser.
Connecting the hoses in this way is a much quicker system for the firefighters. The hoses they use to connect on each floor are shorter and therefore lighter and there is no requirement to run long heavier hoses up through the whole of the building. Using Dry Risers saves time and ultimately saves lives.
What Is A Wet Riser?
A wet riser is a water pipe kept constantly filled and pressurised. It is supplied by either a mains pump, a storage tank and pump or a mains pressure supply.
Generally buildings above 60m high will have a wet riser. This can be identified from the outside as there will be no visible pipework or inlet for the fire brigade. With wet riser systems internal valves on landings stating ‘Wet Riser Outlet’ can be found, usually resembling taps. These can also be protected inside wired glass or lockable metal boxes. At Thor Fire Ltd, we offer a complete design and installation of new wet riser systems for properties and buildings in the UK.
