Definition & Operational Usage of Water Shuttle
What Is Water Shuttle?
A water shuttle is the movement of water via mobile tenders between a water supply fill site and a fire scene dump site, providing sustained flow for rural structural fire attack.
⚠️ Operational Safety Warning:Ensure dump sites have adequate turning radiuses so tenders can exit immediately without backing up.
Why Water Shuttle Matters on the Fireground
When distance to the nearest water source exceeds relay hose capabilities (over 1 mile), water shuttling is the only viable method to deliver continuous water volume to the fireground.
Relevant NFPA Standards
- NFPA 1010: Standard on Professional Qualifications for Firefighters
- NFPA 1550: Standard for Emergency Responder Health and Safety
Field Procedures & Tactical Steps
- Calculate required fire flow GPM for the involved structure.
- Determine round-trip travel time between fill site and dump site.
- Calculate number of tenders required: $Tenders = \frac{\text{Round Trip Time}}{\text{Dump Time}} + 1$.
- Set up dump site with high-volume jet siphons.
- Monitor drafting pumper intake pressure continuously.
Common Context & Application
Utilized in rural fire districts lacking municipal pressurized hydrants during working structure fires.
Frequently Asked Questions about Water Shuttle
What three elements determine water shuttle capacity?
Capacity is determined by: 1) Fill site fill rate (GPM), 2) Tender travel time, and 3) Dump site unloading speed.
What is a portable folding tank?
A portable folding tank is a collapsible metal-frame vinyl reservoir (usually 1,000-3,000 gallons) set up on the fireground to receive water dumped from tenders.
