Which system relies on gravity to move water?

The gravity feed system is designed to utilize gravitational force to move water from a higher elevation to a lower elevation. This method capitalizes on the natural pull of gravity to facilitate the flow of water, making it an efficient option for irrigation and water distribution in various agricultural practices. It does not require pumps or external power sources, ultimately reducing energy costs and maintenance efforts.

In a gravity feed system, water is typically stored in a tank or reservoir positioned at an elevated point. As water is released, it flows through channels or pipes to reach the plants or crops below. This setup ensures a steady and reliable supply of moisture, which is crucial for plant health and growth.

The other systems listed operate on different principles. A wick system moves water through capillary action, relying on the absorption of moisture by wicking materials. The subirrigation system uses a network of pipes below the soil surface to deliver water directly to the root zone, often requiring pumps to maintain water levels. The hydroponic system grows plants in nutrient-rich water solutions, also utilizing pumps to circulate the solution without the involvement of gravity for water movement. Thus, the gravity feed system is unique in its straightforward reliance on gravitational force for water movement.
