Chief, I came from a wet system(hydrants) and just recently moved to more of a rural setting. We are currently using a tanker strike force consisting of six tankers plus the host company's tanker. This a an automatic dispatch. Most of the departments in my area have a Water Supply Officer. His/her sole job is to find and maintain a water supply. easy right? I thought so until I tried it. Your main question is how much flow. That all depends on what your set up is. We use a double 3000 gallon porta-pond with a jet siphon and a host pumper (1500gpm minimum, 1000 gallon tank). The cycle of tankers is one every three to five minutes(sometimes longer) depending on where we get thge water from. This keeps us flowing between 1000-1500gpm. We have some hydrants, but only on the major roads. They are 16-18" mains and can only flow around 1500 gpm. We have a few "monster tankers" but most are 3000 gallon with 10" auto dumps. It is critical to get the water on the road ASAP. I hear some companies waiting for a tanker dispatch cause they think they can get it with theirs. 9 out of 10 times, they are wrong. Like I said, I am new to this "rolling hydrant" system. I hope this helped. Be safe

In Belmont County, Ohio we've coordinated a tanker task force to respond to every fire district in the county. If requested, the FD gets either 5 or 6 tankers and 3 engines. One of the engines is placed at the dump tank site and the other 2 are fill engines, either drafting or using a nearby pressurized system. On a recent barn fire (full of haybales), the task force flowed 557 gpm for 20 hours. Last week a gasoline tanker rolled on I-70 spilling 3000 gallons of gas. The tanker task force was requested and supplied enough water to spread 250 gallons of AFFF foam. In my department, we used it last year to suppliment the pressurized system for a commercial fire. The system works for us but not all of the officers are keen on requesting it right away. Our department has it dispatched on the first alarm for non-hydranted areas and as needed in town.
