What type of system uses gravity to move water from a source to distribution points?

A gravity-fed system is designed to utilize the natural force of gravity to transport water from a source, such as a reservoir or a spring, to various distribution points without the need for mechanical pumps. In this system, water flows downhill from a higher elevation to lower surfaces, allowing for efficient movement by relying on gravitational pull. This method typically leads to lower operational costs and less energy consumption since it does not require additional power for pumping.

In contrast, a pumped system relies on pumps to move water, which requires energy and operational costs associated with maintaining that machinery. A centrifugal system is a specific type of pumped system that uses rotational force to move fluids, while a pressurized system maintains water at a higher pressure to facilitate flow, often necessitating mechanical assistance as well. Thus, the defining characteristic of a gravity-fed system is its ability to naturally harness gravity for water distribution, making it a vital consideration in the design of water delivery systems, particularly for very small water systems.
