In accordance with NFPA 1901, water tenders must be designed to be filled at a rate of at least _____ gpm so that pumpers assigned to the fill site must be rated at that capacity or greater.

1,000 gpm


Tender featuring pumps of ____ gpm or greater rating are often called _______/______

750 gpm


The vacuum tender is able to self-fill from a static water source at a rate of up to _____ gpm with a lift of up to ___ feet. These apparatus are also capable of discharging its water tank at a rate of up to _____ gpm.

2,000 gpm
1,750 gpm


When possible, a water supply source capable of supply at least _____ gpm should be chosen in order to match NFPA recommended rate at which tenders should be filled.

1,000 gpm


Driver/operators must consider the following safety issues when planing a route of travel for water shuttle operations. (7)

> Narrow Roads
> Long Driveways
> Blind curves and intersecitons
> Winding roads
> Steep grades
> Inclement weather conditions
> Freezing water


The primary advantage of the ___________ is the large capacity of its tank that may allow incidents to be concluded before there is a need to refill the tank.

Nurse Tender


NFPA 1901 requires all tenders to have the capability to dump a minimum average flow rate of _____ gpm for the first ___ percent of its tank capacity

1,000 gpm


Any tank, regardless of type, should be set up on a surface that is as level as possible and have a capacity at least ____ gallons larger than the water tank of the apparatus that will supply it.

500 gallons


Formula for Water Shuttle Flow Rate

Flow = (0.9 x TS) ÷ Trip Time

Flow = Flow rate in gpm
TS = Tank size


Formula for Travel Time

Travel Time = 0.65 + (1.7)(Distance)

Assuming avg speed of 35 mph
Travel time = Time in Minutes
Distance = Distance in Miles


Formula for Handling Time

Handling Time = Fill Site Time + Dump Site Time

Time = make and break times + (TS ÷ Fill/Dump Rate)


Formula for Tender Flow Rate

Flow = (0.9 x TS) ÷ (Travel Time + Handling Time)

TS = Tank Size


Effective water shuttle operations are the result of ___ and _____ practices and not _____________.

Safe and Efficient
Excessive Driving Speeds
