Where does relay pumping always begin?

Relay pumping is a method used to supply water over long distances, particularly when the fire scene is far from a reliable water source. In this process, it is essential to start where the available water supply is located to maintain the flow and pressure needed for firefighting operations.

Starting with the source or supply pumper ensures that water is drawn from the most secure and abundant source available. This pumper is responsible for taking in water from a hydrant, reservoir, or another water supply point and then relaying it to the next pumping apparatus in the sequence, typically located closer to the fire scene.

Once the source/supply pumper is operational and supplying water, subsequent pumpers can effectively take turns relaying the water until it reaches the attack pumper, which is positioned as close to the fire as possible. This coordinated effort is crucial in ensuring adequate pressure and flow rates are maintained throughout the relay process.

By beginning with the source/supply pumper, you establish a solid foundation for your water supply chain, allowing for efficient management and delivery of water resources to where they are most urgently needed.
