Gravity-fed systems are designed to move water or other fluids using the force of gravity. These systems rely on a difference in elevation, where water flows from a higher point to a lower point without the need for pumps. Commonly used in irrigation, plumbing, and drainage, gravity-fed systems are efficient and cost-effective. In agriculture, gravity-fed irrigation systems help distribute water evenly across fields. By utilizing natural slopes, farmers can ensure that crops receive adequate moisture without excessive energy costs. This method is also environmentally friendly, as it minimizes reliance on mechanical equipment and reduces energy consumption.
