Study Notes
Water Tender Operations
- Overview: Tender operations are used to supply water for incidents far from water sources where relay pumping is impractical.
-
Operational Modes:
-
Nurse Operation:
- Used to deliver water for direct attack and tank filling at low GPM and short durations.
- Rule of Thumb: < 250 GPM and < 10 minutes of operation.
- Subsequent tenders should connect to a pump intake, not the nurse tender's direct fill.
-
Progressive Tender Supply:
- Utilizes a driveway supply lay with a siamese appliance.
- Tenders connect to the supply line with a siamese and pump the line.
- Recommended for larger GPM deliveries.
- Rule of Thumb: > 250 GPM and > 10 minutes of operation.
-
Nurse Operation:
Supporting Water Tenders
-
Water Supply Officer:
- Should have a separate Tactical Communications Channel.
-
Traffic Control:
- Traffic plans for shuttle operations should be established.
-
Water Source Identification:
- Water sources should be identified while enroute.
- A source engine should be provided at the water supply if possible.
-
Cold Weather Considerations:
- In cold weather, a sanding truck and/or tow truck should be staged for possible water tender issues.
Water Tender Flow Rate Calculation
- Formula: Tanker Flow Rate = Tanker Water Tank Size (in Gallons) - 10% / Travel Time + Handling Time
