What is one crucial requirement for the sprinkler system's water supply?

The requirement for the sprinkler system's water supply to include fire pumps and reservoirs is crucial because it ensures that there is an adequate and reliable supply of water available during a fire emergency. High-rise buildings have unique challenges, including height and pressure requirements, which often necessitate additional equipment to maintain effective water flow to the sprinklers.

Fire pumps are essential for enhancing water pressure to reach upper floors, while reservoirs can provide a reserve supply of water to ensure that sprinklers can operate even if the municipal supply is interrupted or insufficient. This system provides redundancy and stability, which are vital for effective fire suppression. Without fire pumps and reservoirs, a sprinkler system might not function properly in a high-rise scenario, potentially compromising the safety and effectiveness of the fire protection measures in place.
