What is the function of a drainage system in a standpipe configuration?

The function of a drainage system in a standpipe configuration is to prevent water accumulation and maintain system integrity. In standpipe systems, which are designed to provide a reliable source of water for fire suppression, it is crucial to manage water effectively to avoid issues such as stagnation and corrosion.

When water accumulates in the system, it can lead to several problems, including the risk of bacterial growth, poor water quality, and the potential for system failure due to blockages or corrosion of pipes. A properly designed drainage system allows for the regular removal of water that may not be used, ensuring that any residual water does not compromise the integrity of the standpipe system. This contributes to overall functionality and reliability in emergency situations.

The other options focus on different aspects that do not pertain directly to the primary purpose of a drainage system. While increasing water supply pressure, monitoring water quality, and filtering debris are all relevant considerations in a water supply system, they are not the main functions of the drainage system in a standpipe configuration.
