Pumpers
  • Minimum of two used in shuttle one at fill site
    and one at dump site.
  • Must have a minimum pump capacity of 1,000gpm to
    conform to NFPA 1901

4
Tenders/Tankers
  • Must have tank-to-pump line capable of supplying
    the pump 500 gpm until at least 80 of the tank
    is empty
  • Must be equipped with at least one external
    connection to allow filling at the rate of 1,000
    gpm
  • Must have a discharge capable of discharging 90
    of the tank volume at an average rate of 1,000gpm
  • May empty the tank with a gravity or a
    jet-assisted dump

Gravity v.s. Jet-Assisted

Gravity v.s. Jet-Assisted
7
Disadvantage of Jet-assisted
  • The apparatus must have a fire pump
  • The pump must be engaged before dumping water
  • Water can be discharged if the pump is not
    operating, but at a lower rate than it would in a
    gravity dump.
  • The apparatus purchase cost is increased

8
Setting up a Water Shuttle
  • Location of the dump site
  • Location of the fill site

Positioning Fill Site Apparatus
  • If possible, use a pumper to fill tenders,
    regardless of whether a hydrant or static water
    supply is used.
  • Fill tenders at a rate of 1,000 gpm
  • Use LDH on the hydrant steamer connection.
  • If necessary, use multiple MDH in addition to the
    LDH if the hydrant is on a strong main.
  • When positioning for drafting, seek a spot that
    requires a minimum amount of lift or hard intake
    hose.

14
Positioning Fill Site Apparatus
  • If the static water supply is inaccessible and
    portable pumps are used, locate them no further
    than 100 feet from the pumper
  • Regardless of whether a hydrant or static water
    source is used, ensure that a small discharge
    line continuously flows from the fill site
    pumper.

15
The Fill Site
  • Determine where the tender driver/operator should
    park on arrival
  • Mark where the tender should stop with a traffic
    cone opposite the driver/operators side door
    window.
  • Make sure that each hoseline used should have a
    gate valve.
  • Lay out hose according to the tenders fill
    valves.
  • Install a gate valve between the last and second
    to last sections of each hoseline
  • Install Stortz adapters on hoses as necessary
  • Assign a radio-equipped firefighter to supervise
    the manifold if used.

16
Fill Methods
  • Fixed or portable overhead pipes at the static
    water source
  • Permanent or portable manifolds

17
Operating Shutting Down
  • Keep the fill site pumper in gear with tender
    fill lines charged at all times.
  • Continuously flow a waste line from fill site
    pumper to prevent loss of prime or pump
    overheating
  • Assign makeand-break personnel one firefighter
    to handle each laid out tender fill line, make
    fill connection when tender arrives, and
    disconnect hose when tank is full.
  • Ensure that tender drivers remain in their
    apparatus cabs

18
Operating Shutting Down
  • Monitor the ground conditions and adjust fill
    site location if site becomes too soft because of
    spilled water.
  • Once the incident commander orders the shuttle
    shut down, make sure all tenders are full before
    releasing them, unless the site is supplied by a
    static water source.
  • Release apparatus based farthest from the scene
    first
  • Once all tenders have been refilled and/or
    released, shut down the fill site pumper and
    prepare it for return to service.
  • If water came from a static source, flush all
    pumps and equipment before storing.
