Standpipes are built to bring water directly inside a building where firefighters are operating. Their main purpose is to provide an accessible water supply on multiple floors so crews can quickly connect attack lines without hauling water up stairs from exterior hydrants. This is especially crucial in high-rise or large buildings, where carrying long lengths of hose from outside would be impractical and time-consuming. Standpipes work with the building’s water supply and allow fire departments to feed hoses with water right at the scene, improving speed and effectiveness of interior fire attack. They do not replace exterior hydrants, they do not eliminate the need for hoses, and they are not used for ventilation.
