This photo very clearly illustrates the 800 or so feet of preconnected 5 inch supply hose carried on this pumper, along with the valved hydrant connection.
This enables two or three pumpers to operate from a single hydrant, as hydrants can often suuply more than 2000 US GPM.
In metric terms, this equates to around 240 meters of 125mm hose. The hydrant output translates to around 7300 liters. Most North American pumpers can move between 4500 LPM and 5500 at 10AT.
The truck also carries a similar load of preconnected 2.5 inch (65mm) attack hose, along with 45mm attack hoses in the bed and in the crosslays above the pump: these can be accessed from either side, and are usually around 200 feet or 60 meters long. These are used for interior attack and on small fires, and can be deployed very rapidly.
Yjis hose load is typical, but each department loads its pumpers differently, to meet local conditions and requirements. In large cities, hose loads also vary between companies, because there are different needs from one company response area to another.
