(Alternative Water Supply)
Criteria concerning water delivery by fire department apparatus include:
When a tanker relay system is used, the volume of the tanker capacities is reduced by 10% for spillage, under filling and incomplete unloading.
Travel time of apparatus is calculated from the formula: T = 0.65 + 1.7D (T=Travel Time D=Distance)
Slower speeds will be used for underpowered apparatus, or apparatus laying hose lines.
The delivery rate of a tanker relay system will be affected by the rate of filling and of dumping of the tankers and the usable volume of the fire-site folding tanks or other fire-site storage.
Credit may be given for apparatus responding from outside the municipality or legal fire district upon communication
facilities, handling of alarms, inter-department training, fire grounds communication and time of arrival at fires.
Please provide us with a map showing:
NOTE: Continuous access road to within ten (10) feet under adverse weather conditions to all
supply points is required.
Please provide a description of each water supply point; and:
Please give us a description of a recent fire or demonstration more than 1000 feet from a hydrant, where 250 - g.p.m. or more was delivered for one hour, giving the following information:
a. Make - year.
b. Pump capacity.
c. Tank capacity.
d. Functions (Tanker, Pumper, etc.).
The folding tanks used, if any, with the following information for each:
Description of the overall operation
Total capacity.
Usable capacity = Total capacity less volume that cannot be pumped out when drafting from tank.
Set-up time.
Name of apparatus carrying each folding tank.
If different combinations of apparatus are used in various sections of the municipality or legal fire district, list the combinations with the data in Nos. 7 and 8 above and show the areas on the map.
For each vehicle used to carry water, indicate the actual time to discharge the capacity of the tank and the actual time necessary to fill the tank using the pumpers that normally will be used for filling. If different capacity pumpers will be used for filling, the time shall be obtained for filling with each capacity pumper.
NOTE: The actual time to be recorded shall be the time necessary for the vehicle to travel 200 feet to the site, maneuver into position, fill or dump and travel 200 feet from the site.
When the water supply is delivered through a hose line, indicate the time for a pumper to travel 200 feet to a water supply point, connect suction and discharge hoses and commence pumping. If the water supply points are both hydrants and drafting sites, the time shall be obtained for both types of water supply points.
When the water supply is delivered through a hose line, indicate the lengths and diameter of the hose line used for the time trial and the time from when the pumper begins to fill the hose line until a solid stream of water is delivered at the other end.
Current equipment inventories for all apparatus in service and in reserve in your municipality or legal fire district.
