Maintaining a humidity level of 95% or greater in the water tank room is essential for several reasons related to the operational efficiency and safety of water systems. High humidity assists in preventing evaporation, which can lead to significant water loss and might compromise the water quality if contaminants are introduced. It also fosters a stable environment, reducing the risk of dryness that could negatively affect both equipment and biological processes, such as the growth of necessary microorganisms for water treatment.

In addition, a humidity level at or above 95% helps in minimizing the formation of condensation on surfaces, which could lead to corrosion, mold growth, and other maintenance issues. This is especially critical in environments with sensitive water quality standards, where fluctuations in humidity could affect the reliability of testing and monitoring systems.

Therefore, ensuring that the humidity level is consistently maintained at 95% or greater is crucial for both operational and environmental health in facilities managing water tanks.
