What is the primary purpose of standpipe systems in buildings?

The primary purpose of standpipe systems in buildings is to supply water for firefighting. Standpipe systems are crucial components of a building's fire protection plan, specifically designed to deliver water to designated locations throughout the building where firefighters can access it quickly and efficiently when responding to a fire. These systems typically consist of a network of pipes, valves, and hoses that enable fire personnel to connect and utilize water supplies from the building's plumbing or an external source.

By providing a ready and accessible supply of water directly to the floors of the building, standpipe systems enhance the ability of firefighting crews to combat fires effectively, especially in high-rise structures where traditional fire hoses may not reach. This capability is vital for ensuring the safety of occupants and minimizing property damage during firefighting operations.
