Multiple Choice, Single Answer

Read the passage and answer the question.

Many rural communities without reliable electricity depend on elevated water towers to maintain consistent water pressure. Unlike systems that rely on constant pumping, a water tower uses gravity: pumps fill the tank during periods of low demand, often overnight, and stored water flows down to homes when demand rises, requiring no additional energy at that moment. This design also acts as a buffer during power outages, since gravity continues to push water through pipes even if pumps stop working. Engineers size the tank's height and capacity based on the community's peak usage hours and the elevation of the surrounding land, since insufficient height can result in weak pressure at taps located far from the tower.
