Misting systems use how much water?

• A. Greater than 5 gph
• B. 3 - 5 gph
• C. Less than 2 gph
• D. 1 - 3 gph

Answer: (C)

Misting systems are designed to deliver very small amounts of water per emission so the droplets stay fine and evaporate quickly, providing cooling with minimal runoff. That low flow per nozzle is what makes it a true mist rather than a spray. Because of this, most misting nozzles operate at well under two gallons per hour per emitter. Using higher flows—such as those in the 3–5 gph range or above 5 gph—produces larger droplets, uses more water, and increases the chance of damp surfaces or runoff, which reduces overall water-use efficiency. So the option that reflects the typical misting approach is less than 2 gph per emitter.
