Standpipes, Hose Reels and Landing Valves
A clear guide to the manual firefighting water systems in a building — wet and dry standpipe risers, landing valves for the fire service, and hose reels for first-aid firefighting by occupants.
Sprinklers act automatically, but firefighting also depends on manual systems that deliver water exactly where people direct it. Standpipes, landing valves and hose reels are the pipes and outlets that put a charged water supply on every floor, ready for either occupants or the fire service to use a hose.
These systems are simple in principle but critical in practice: they must reach every part of a building, hold adequate pressure at the highest and most remote outlet, and be reliably supplied from the fire pumps. This guide explains how each part works and how they fit together.
How it works
The standpipe riser. A standpipe is a vertical pipe (riser) that carries firefighting water up through a building so that outlets are available on every floor without running long hoses up stairs. Tall buildings have one or more risers, often located within protected stair shafts so firefighters can connect to them safely. The riser is the backbone that landing valves and hose reels tap into.
Wet versus dry risers. A wet riser is kept permanently full of pressurised water, fed continuously by the fire pumps, so water is instantly available at any landing valve — used in taller buildings where speed and height demand it. A dry riser is normally empty; the fire service charges it with water through a fire brigade inlet at ground level when needed, and is suited to lower buildings. The choice depends on building height and the local authority’s requirements.
Landing valves. At each floor the riser has a landing valve — a controlled outlet to which the fire service connects their hoses. Opening the valve releases the riser’s water at the working pressure needed to fight a fire on that floor. Landing valves are intended for trained firefighters, located where they can be reached safely, typically at protected stair landings.
Hose reels. A fire hose reel is a first-aid firefighting device for occupants. It is a fixed reel of semi-rigid hose permanently connected to the water supply, with a control nozzle at the end. A person simply pulls out the hose, opens the valve and directs water at a small fire in its early stage. Hose reels are positioned so that the hose can reach all parts of the floor they cover.
Working together with the pumps. All of these outlets rely on the fire pump set and stored water supply to provide guaranteed pressure and flow. The system is sized so that the required number of outlets can run simultaneously at the most demanding point — the highest, most remote landing valve — while still delivering adequate firefighting pressure. Regular flow testing confirms the network continues to meet this requirement.
Main types
In the UAE
- Standpipe, hose reel and landing-valve provision in the UAE follows the UAE Fire & Life Safety Code of Practice (referencing NFPA standards), enforced by Civil Defence — in Abu Dhabi, Abu Dhabi Civil Defence (ADCD).
- These systems require Civil Defence design approval, inspection and witnessed flow/pressure testing, and must use approved/listed valves, hoses and components.
- Building height and use determine whether wet or dry risers are required and how many outlets are needed, and risers are typically located within protected stairs for safe firefighter access.
How GPR applies this
As an Abu Dhabi firefighting contractor, GPR designs and installs complete manual firefighting water systems — wet and dry standpipe risers, landing valves at every floor, hose reels and cabinets, and the fire brigade inlets that supply them. GPR coordinates these outlets with the fire pump set and storage, sizes the network for adequate pressure at the most remote outlet, prepares the layout for ADCD review, and flow-tests the installation to UAE Fire & Life Safety Code requirements.
Frequently asked questions
What is the difference between a wet riser and a dry riser?
A wet riser is kept permanently full of pressurised water for instant use, while a dry riser is normally empty and is charged with water by the fire service through a ground-level inlet when needed; building height usually decides which is required.
What is a landing valve used for?
A landing valve is a controlled outlet on the standpipe riser at each floor where the fire service connects their hoses to fight a fire on that level using the riser’s pressurised water.
Who uses a fire hose reel?
A fire hose reel is intended for building occupants as first-aid firefighting equipment, allowing someone to tackle a small fire in its early stage before the fire service arrives.
What is a fire brigade inlet (breeching inlet)?
It is a connection at ground level where the fire service pumps water from their appliances into a dry riser to charge it, or to boost the supply to a wet riser during firefighting.
Do these systems need Civil Defence approval in the UAE?
Yes. Standpipe, landing-valve and hose-reel designs must be approved by Civil Defence, use approved/listed equipment, and pass witnessed flow and pressure testing before the building can be occupied.
