Dry & Wet Risers
Dry & Wet Risers
A Dry Riser is a system of valves and pipework which enables the Fire Service to pump water on to the uppeer floors of a building. A Wet Riser is a system of valves and pipework which are kept permanetly charged with water.
A dry riser system is an empty pipe running up the inside of a building which can be connected to by firefighters and used as a pressurised water system. There will be inlet connections on the outside of the building – or in fire escape areas – for the fire services to access, allowing the water to be pumped up to valves on upper floors on the inside.
This makes things easier for firefighters who are tackling a blaze in a building with multiple floors, with most systems installed up to a max of 50m above the fire service access level.
These systems are designed to provide pressure on the upper floors of a building, so need to be planned into the construction of a building carefully.
