Why is it important to maintain adequate flow capacity in fire service mains?

Maintaining adequate flow capacity in fire service mains is crucial to facilitate effective firefighting efforts. Fire service mains are designed to deliver sufficient water supply to fire protection systems, such as hydrants and sprinklers, which are essential for controlling and extinguishing fires. When a fire occurs, firefighters rely on the availability of water at the necessary pressure and volume to combat the blaze effectively. Insufficient flow capacity can hinder firefighting operations, leading to increased danger for both responders and the public, and potentially resulting in greater property loss. Ensuring that fire service mains have adequate flow capacity directly impacts the safety and effectiveness of firefighting operations, making it a critical aspect of fire protection planning and infrastructure.
