Which statement regarding treated water storage is true?

Treated water is stored in clear wells specifically designed for this purpose. Clear wells are large water storage facilities that allow for the temporary holding and equalization of treated water before it is distributed to the water supply system. They are essential in ensuring the safe and efficient delivery of clean drinking water as they help reduce the risks of contamination, maintain water quality, and provide a buffer to meet fluctuating demand.

While the other statements may contain elements of truth, they do not capture the primary characteristic associated with treated water storage. For example, although treated water can be stored in tanks that may be pressurized, this is not a defining feature of treated water storage specifically. Similarly, storage tanks can be located above or below ground, and not all treated water necessarily needs to be stored on-site, as it can be transmitted through pipelines to various locations depending on the infrastructure and operational needs of the water supply system.
