Dry & Wet Risers

A dry riser is made up of a system of valves and pipework that that can be externally connected to a pressurised water source, enabling the Fire Service to pump water up to upper floors of a building. A wet riser is also comprised of a system of valves and pipework, but in this case they are kept permanently filled with water.

Risers are installed within large scale buildings for the Fire Service to deliver vast quantities of water to fight a fire. Dry risers are kept empty of water, and wet risers are permanently charged with water either directly from a storage tank, booster pumps or fed directly from the town’s main water supply.

Due to the positioning of risers, they are often prone to vandalism and neglect. To ensure full working order for the Fire Service, in accordance with British Standards all Dry and Wet Riser Systems should be maintained on a 6 monthly basis and hydraulically pressure tested annually. Our engineering teams carry the necessary pumping and testing equipment to cater for all types of riser systems.
