Gravity-Fed Irrigation Guide: Pressure, Flow & Tips for Better System Design
Gravity-fed irrigation uses elevation to create water pressure. By raising a reservoir above the growing area, gravity creates the pressure needed to move water through the irrigation system without a pump or pressurized water connection. Because gravity systems operate at relatively low pressure, reservoir height, tubing size, water demand, filtration, and system layout all affect performance. This guide explains how those pieces work together and how to design a reliable gravity-fed irrigation system.
