Water system standpipes are vertical and horizontal piping networks integrated into a building’s fire protection system, designed to provide a dedicated, accessible water supply for firefighting operations—especially in multi-story buildings, large complexes, and industrial facilities. These systems allow firefighters or trained personnel to quickly connect hoses inside the building, ensuring rapid deployment of water to upper floors or hard-to-reach areas.
Standpipes are classified in accordance with NFPA 14, European Norms, and local code requirements. They are fed from a riser, for which types include:
Wet (water-filled and ready for immediate use)
Dry (air-filled, water introduced when needed)
Water supply may come from the building's main water system, dedicated fire pumps, or fire department connections (FDCs), ensuring adequate pressure and flow under emergency conditions.
Each standpipe system may include:
Landing valves (2.5")
Fire hose racks (1.5" or 2.5")
Fire hose reels (typically 1")
—all of which may be equipped with optional pressure-regulating devices where required by code
These elements are frequently housed within firefighting water system cabinets, ensuring equipment is protected, clearly labeled, and accessible for trained personnel. Together, standpipes and associated cabinetry form an integrated, code-compliant fire protection system, critical for effective emergency response and life safety in modern building infrastructure.
