Is it necessary to screen the vent on a water storage unit?

The vent on a water storage unit is designed to allow air to enter and exit the tank as water levels change, which helps to maintain pressure and prevent loss of structural integrity. It does not require screening because it is intended to remain unobstructed to function effectively. Screening could restrict airflow, potentially leading to issues such as pressure imbalances or structural damage.

In addition, water storage facilities often have design features that help maintain a safe and secure environment. This includes maintaining proper water quality through other means, such as maintaining appropriate disinfection protocols and ensuring that the overall design of the storage system mitigates risks of contamination without needing a screened vent. Therefore, the necessity to screen the vent is negated by the ability of the existing design features to proactively manage air exchange and safeguard water quality.
