Do firefighters use wet water?

Do fire trucks use just water?
Yes, fire engines usually pump regular water. That water may or may not be potable, depending on the source. In an urban or suburban area, the engine company will usually hook up to a hydrant for water supply.
Why do firefighters use water to put out fires?

Can water be made wetter?
Water can be made wetter by adding a compound to it. … So far, we have learned that water becomes “wetter” by lowering its surface tension. Water’s behavior is defined by its surface tension. We benefit economically by making the water wetter since we increase its efficiency, requiring less water to put out flames.
Do ladder trucks carry water?
