Wet and Dry risers are intended for the use of the Fire Service to provide a readily available means of delivering considerable quantities of water.

What is the difference between a dry riser and a wet riser?

A Dry Riser is a system of valves and pipework which enables the Fire Service to pump water on to the upper floors of a building.   A Wet Riser is a system of valves and pipework which are kept permanently charged with water.

Where do you find dry / wet risers?

Dry risers will be found:

  • in buildings over 18 metres above ground level
  • in low level buildings where the are excessive distances from entrances (60m)

Wet risers will be found in buildings over 60 metres above ground level.

Service and maintenance

Risers are prone to neglect and vandalism.  If your fire risk assessment concludes that you would need the intervention of the Fire Service to fight a fire, you must ensure that your riser systems or hydrants are working properly.  There are severe penalties should the rising main fail to work for the Fire Service.  Leaking water from a wet riser could also cause considerable damage to your property.
