What is the function of a water storage tank?

A water storage tank serves multiple essential functions in a water distribution system, with one of its primary roles being to provide a backup water supply and maintain pressure within the system. By storing water, these tanks ensure that there is a readily available source of water, especially during peak demand times or in emergencies when the demand exceeds the supply from treatment plants or other sources.

The tank's ability to maintain pressure is critical for effective water distribution throughout the system. It helps ensure that water reaches all areas, even those at higher elevations, and supports consistent flow and pressure at consumer taps. In the case of outages or maintenance activities in the distribution network, the stored water can be released to meet consumer needs without interruption.

Other options, while relevant to water management, do not align with the primary purpose of a water storage tank. Such tanks are not designed for treating wastewater or filtering impurities, nor are they primarily intended for temperature control of water. These processes typically occur in different facilities or equipment specifically designed for those functions.
