What does elevated storage in water systems primarily support?

Elevated storage in water systems primarily supports fire protection requirements. When a community has elevated storage tanks, these tanks maintain a consistent supply of water at a higher pressure, which is crucial during firefighting efforts. The elevation allows for the rapid release of a significant volume of water, ensuring that emergency services can effectively combat fires. This storage capacity is particularly important in areas where immediate access to large amounts of water can be the difference between controlling a fire quickly or facing a more catastrophic situation.

While the other options, such as water quality maintenance, emergency water supply, and public health safety, are significant aspects of water system management, the primary function of elevated storage directly relates to ensuring sufficient water availability for fire suppression activities.
