Study Notes

Water Supply Operations Guidelines

  • Ensure subsequent units are charged promptly.
  • Standpipe system should receive water before the sprinkler system during firefighting operations.

Rural Water Supply Protocol

  • First due engine officer must announce fill site location via radio for situational awareness.
  • ECC (Emergency Communications Center) must log the fill site location in event comments.
  • Rapid intervention dispatch and water supply task force should be dispatched immediately at the first indication of a working event.

Initial Water Supply Initiation

  • Initial water supply typically initiated by the first due engine using a forward lay with a clappered siamese.
  • If the first due engine fails to initiate water supply, it must instruct the second due engine via radio.
  • Second due engine should initiate a layout with a clappered siamese if the first due engine does not.

Conditions for Not Laying a Line

  • The first due engine may choose not to lay a line in rural settings if:
    • The first due engine and attack tanker arrive simultaneously.
    • Laying the line obstructs the second engine or tanker from accessing the scene.
    • Access to the scene is uncertain, especially if the structure is not visible from the road.

Water Supply Operations for Rural Incidents

  • Water supply operations in rural areas focus on the attack tanker, ensuring co-location of the first, second engine, and attack tanker.
  • Early establishment of a Water Supply Officer (WSO) is crucial for sustainable incident water supply.
  • Preferred options for expanding water supplies include:
    • Utilizing dual 4” lines in a relay when exceeding 2,000 feet or 1,000 GPM.
    • Charging only supply lines sequentially when using dual lines.
    • Ensuring the next engine in the relay is ready before charging supply lines.

Cistern Usage and Fill Sites

  • Cisterns with under 30,000 gallons should not serve as the sole fill site for structure fires; can only support operations while additional water supplies are established.
  • Fill sites should operate one at a time, and each must fill tankers at a minimum rate of 1,000 GPM.
  • Hydrant fill sites require the fill site engine to be connected to the hydrant for tanker filling.
  • Fill sites are named by physical address rather than common names or numbers.

Parking and Static Sources

  • Keep roads clear for tanker access to the siamese.
  • On-site static water sources require assignment of an engine to draft from the source, connecting the supply line to the attack tanker's pump intake.

Dump Site Operations

  • Establish portable tanks in designated locations with an engine drafting from the tank.
  • The drafting engine supplies water through a clappered siamese to the fireground.
  • Effective dump site operations require personnel commitment and a WSO to manage the site.
  • Additional personnel must be allocated to the dump site as needed, with collaboration between the second due tanker driver and third due engine driver for setup.

Relay Pumping Operations

  • A relay operation can be initiated if a reliable water source exists within 3,000 feet of the clappered siamese.
  • Consider roadway size limitations, relay length, and required fire flow when constructing a relay setup.

Water Supply Operations Guidelines

  • Ensure subsequent units are charged promptly.
  • Standpipe system should receive water before the sprinkler system during firefighting operations.

Relay Pumping Operations

  • A relay operation can be initiated if a reliable water source exists within 3,000 feet of the clappered siamese.
  • Consider roadway size limitations, relay length, and required fire flow when constructing a relay setup.
