In which scenario is an elevated tank most commonly used?

An elevated tank is most commonly used in very flat areas to create water pressure. In regions where the topography is flat, gravity alone does not provide sufficient water pressure for distribution throughout the system. By placing a tank at a height, water can flow downwards due to gravity, generating the necessary pressure to ensure efficient water distribution to homes and businesses.

This design limits the need for additional pumping systems, simplifying operations and reducing energy consumption. Elevated tanks also help maintain water quality by minimizing stagnation, as water can be cycled through the system more effectively.

Other scenarios like mountainous regions, emergency water storage, or preventing water hammer involve different considerations and solutions for water distribution and pressure management, making elevated tanks particularly beneficial in flat areas for generating necessary pressure.
