What is the typical height range of water towers?

The correct choice, which indicates a typical height range of 50-130 feet for water towers, reflects the common design and structural requirements for these facilities. Water towers must be constructed at a height sufficient to create the necessary water pressure for distribution in municipal systems. Heights within this range allow for effective pressure management and ensure that water can be delivered to higher elevations within a service area.

Water towers are engineered to store large volumes of water, and their elevation plays a crucial role in maintaining consistent pressure throughout the distribution system. While some smaller water storage tanks might exist below this height range, typical municipal water towers are designed to be taller to meet the demands of larger populations and varied topographies.

The other options do not encompass the standard heights for water towers, as they either fall short of the minimum necessary for effective water pressure (like 20-40 feet) or extend beyond the typical structural norm found in the majority of urban water infrastructure (like 70-150 feet), which is less common. Hence, the 50-130 feet range is recognized as the standard for many water towers.
