What is the primary purpose of a standpipe system?

The primary purpose of a standpipe system is to provide a means of firefighting water supply for buildings. Standpipes are integrated into the architecture of a building, allowing firefighters to access water quickly and efficiently while fighting a fire. This system is vital, particularly in high-rise buildings, where fire hoses may not reach the upper floors.

Standpipes ensure that adequate water pressure and flow are accessible at the required levels to combat fires, making them an essential component of fire safety infrastructure. The design and operation of a standpipe system are tailored to facilitate rapid response in emergencies, ensuring that firefighting efforts can be conducted effectively and safely.

Other options, while related to water usage, do not align with the primary function of a standpipe system. Supplying water for plumbing fixtures, draining excess water from roofs, and providing irrigation for landscaping each serve different purposes that do not involve direct firefighting capabilities.
