Motivation: The ability to move water from the source to the fire scene in a rural firegfighting operation is vital to the successful outcome of the incident.

Student Performance Objective (SPO): Given information from discussion, handouts, and reading materials, describe and recognize the proper methods of establishing a water shuttle drafting operation, operating controls and appliances.

Enabling Objectives (EO):

EO 1-1-1 Identify the apparatus requirements for a water shuttle. (NFPA 1002 (1998), 8-2.1, 8-2.2,

                 8-2.3)

EO 1-1-2 Identify the requirements for setting up a water shuttle operation. (NFPA 1002 (1998),

                 8-2.1, 8-2.2, 8-2.3)

EO 1-1-3 Describe the fill site operations for a water shuttle. (NFPA 1002 (1998), 8-2.1, 8-2.2,

                 8-2.3)

EO 1-1-4 Describe the dump site operations for a water shuttle. (NFPA 1002 (1998), 8-2.1, 8-2.2,

                 8-2.3)

EO 1-1-5 Describe how to evaluate tanker performance in a water shuttle operation. (NFPA 1002

                (1998), 8-2.1, 8-2.2, 8-2.3)

I. WATER SHUTTLE APPARATUS (EO 1-1-1)

A. Introduction

  1. Water shuttle operations used to supply water to emergency scenes far from water supply source

       where relay pumping not practical

  2. Water shuttles involve process in which tankers deliver water to emergency scene, travel to filling

       site, reload with water, and return to emergency scene to dump again

  3. Water shuttle operations rely on constant movement of apparatus between emergency scene and

       water supply source

  4. Two primary types of apparatus required to operate effective water shuttle operation: pumpers and

       tankers

B. Pumpers

  1. Effective water shuttle operation requires at least two pumpers to be successful

  2. One pumper positions at water supply source and used to fill empty tankers at fill site

  3. Depending on number of tankers in shuttle and capacity of water supply source, more than one fill

      site or fill site pumper used to allow two or more tankers to be filled simultaneously

  4. Second pumper located at or near emergency scene and used to draft water from portable water

       tanks at dump site

  5. Depending on dump site proximity to emergency scene, dump site pumper can be attack pumper

      or simply relay water to another pumper supplying attack lines

  6. Fill site pumpers should have minimum pump capacity of 1,000 gpm

C. Tankers

  1. Department must choose size of tank for apparatus based on local water requirements, road

      conditions, and bridge weight restrictions

  2. Tankers with water tanks less than 2,500 gallons and quick unloading times most efficient tankers

      for use in water shuttle operations

  3. If existing tank being retrofitted to add large diameter, direct tank discharge valve, follow

      manufacturer’s instructions to ensure that tank not structurally damaged as result of installation

  4. Two primary ways to increase efficiency of water shuttle operations to decrease amount of time

      required to fill and amount of time to unload tankers

  5. All other parts of water shuttle such as response time and travel time between dump and fill sites

      fairly constants

  6. Attempting to make up time during road travel dangerous

  7. Tankers that use 3-inch supply lines for filling should have at least two external fill connections

      piped directly to tank

  8. If LDH used, one fill connection to tank adequate
