What should be a primary concern before cleaning and painting a water storage facility?

A primary concern before cleaning and painting a water storage facility is ensuring that adequate water storage provisions are made. This is crucial because the water storage facility is essential for maintaining a reliable water supply. During the cleaning and painting process, the facility will be temporarily out of service, which means that alternative water storage must be arranged to meet the needs of the community or system being served. If sufficient provisions are not planned, there could be disruptions in water availability, affecting users and potentially leading to public health issues.

While aspects like proper ventilation, the cost of materials, and scheduling are important considerations in managing the project effectively, the immediate priority must be maintaining an uninterrupted water supply. Therefore, ensuring that there are enough alternative sources of water while the facility is being serviced takes precedence over other logistical aspects.
