Water mist is supplied from which water source?

• A. Seawater
• B. Potable water
• C. Graywater
• D. Reclaimed wastewater

Answer: (B)

Water mist systems rely on clean water to form the tiny droplets that absorb heat quickly and to keep the spray heads from clogging. The water quality matters a lot because impurities can foul the many small nozzles and cause corrosion or mineral buildup in the system. Seawater contains salt and minerals that can damage equipment; graywater and reclaimed wastewater carry oils, detergents, organic matter, and other contaminants that can foul nozzles and create hygiene concerns. Potable water, meeting drinking-water standards, provides the cleanest, most compatible supply for the misting system, ensuring reliable operation and minimizing maintenance issues. Therefore, water mist is supplied from potable water.
