What is a 'relay pumping operation'?

A 'relay pumping operation' is a technique that involves the use of multiple pumpers working in tandem to transport water over a long distance. In this operation, one pumper supplies water to the next, which in turn can supply additional pumpers or direct water to the fire scene. This method is vital in situations where the water source is far from the fire location, as it ensures a continuous and sufficient supply of water is available for firefighting efforts.

Utilizing multiple pumpers in a series allows for more efficient use of resources and maximizes the available water pressure, which is crucial in combating fires effectively. The positioning of each unit is strategically planned to maintain pressure and to ensure that water travels as efficiently as possible through the hoses connecting the pumpers. This operation is particularly beneficial in large-scale incidents or rural areas where water sources may be limited or distanced from the incident.
