Although most US pumpers settle for around 600 to 800 feet of LDH - principally for hydrant connection - this big load must be very useful for relaying water in areas where hydrants are far apart, or where the department needs to rely on open water or static supplies.
Difficult to tell, but this looks like five inch. If so, a regular pump operating at 10AT can move over 3, 000 LPM all the way through this 2,000 foot hose lay - because friction losses are very low.
Five inch is by far the most popular LDH in use here, but 4.5, 4.0 and 3.5 are also carried instead in some places.
Standard 2.5 or 3.0 inch hose can be used for hydrant connection, but LDH (or six inch suction) is usually the preferred SOP.
Wellsboro could move some big water. In photo 42068 you will note that of the 4 apparatus in the picture 3 have 2 master streams and 2 are carrying LDH.
This looks a lot like Engine 1-13, an 1980 1750 GPM ALF pump which is still in service! According to the FD website, it actually has a 2400 foot 5 inch hose load and carries two portable monitors as well as a deck gun.
It is one of four pumpers at their fire station, and part of a fleet which also includes an aerial quint, a heavy rescue, brush trucks, a tanker and three ambulances.
If you check out this department's website, you will see an impressive fleet of high capacity pumpers and a definite focus on big water. This volunteer outfit does not have any very new rigs, but they do have a lot of capacity with the units they have available!
