What is an essential function of the source/supply pumper in a water relay operation?

In a water relay operation, the source/supply pumper plays a crucial role in ensuring that water is effectively delivered to the forward operation area. Initiating the water supply is a key function because it establishes the flow of water needed to support firefighting efforts at the incident scene. Without this initiation, there would be no water to transport to the attack pumper, which is essential for combating the fire.

Once the source/supply pumper initiates the water flow, it may be responsible for maintaining a steady supply, but the first step in any relay operation is indeed to initiate that water flow. This action typically involves opening a valve in the water source, whether it’s a hydrant, a tanker, or another type of water source, to begin the transfer of water through the relay system.

While maintaining constant pressure, determining flow requirements, and connecting multiple hoses are all important aspects of a successful water relay operation, they are secondary to the initial step of getting the water moving toward the emergency scene. Ensuring that the water supply is initiated properly sets the stage for effective fire suppression tactics.
