Why are discharge manifolds used in relay operations?

Discharge manifolds serve a crucial function in relay operations by allowing multiple attack pumpers to draw water from a single source. This setup is vital in scenarios where high volumes of water are needed, particularly during large-scale incidents or when resources are stretched thin. The manifold enables fire apparatus to connect to a collective network, ensuring that multiple pumpers can operate efficiently and simultaneously, coordinating their efforts to supply water to the fire scene.

In relay operations, the ability to support more than one attack pumper enhances the overall firefighting capability by allowing a more unified and strategic approach to resource management. This collective action helps maintain an adequate water supply, which is essential for effectively combating fires.
