Tanker Shuttle
A tanker shuttle is a rotation of water-hauling apparatus that carries water from a distant fill site to the fire, sustaining a supply where there are no hydrants. The shuttle's sustained flow depends on the cycle time and the number of tankers.
In rural operations, mobile water supply replaces a hydrant. Tankers cycle between a fill site and a dump site near the fire, dropping their loads into a portable tank the attack engine drafts from.
The sustained flow the shuttle can deliver is set by how much each tanker carries divided by how long its round trip takes — and by how many tankers are in rotation. Hitting a target flow is a logistics problem as much as a pump problem.
