WET RISER SYSTEMS
Wet risers are systems of pipework permanently charged with water ready to use in emergency situations. This is as opposed to dry risers which have water pumped through them via the inlet breaching valve from a fire service appliance.
Wet risers should be installed to buildings 50m above the level where fire & rescue can access their vehicles, This is necessary as the pumping pressure required to charge the riser is higher than can be provided by a fire service vehicle, and to ensure an immediate supply of water is available at high level.
Wet risers are charged with water supplied from dedicated pressure pump and tanks , situated in an on-site pumphouse, complete with pressure reducing landing valves situated in specified locations on each floor.
Wet risers should be inspected and tested regularly to ensure equipment is functioning correctly and ready for use. Problems can be very serious in the event of a fire, and are typically caused by vandalism or left, blockages or pipework failure or by connection failure or outlets being open.
