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.
