Tenders are used to shuttle water to the fire scene and can hold a large amount of water. It draws water filling the tank. The water is then delivered to a drop tank (large portable folding pool) at the scene of the fire. The tender then returns to the water source to refill. During a working fire, a tender may make many trips between the water source and the fire scene.
A tender is dispatched to any structure fire in an area of the city not served by hydrants and to all structure fires in the winter (in case hydrants freeze up).
