Gravity-Fed Water Systems: Moving Water Without a Pump The image illustrates a gravity-fed water system, a simple yet powerful method of transporting water using elevation and natural pressure—no electric pump required. These systems have been used for centuries and remain highly relevant today, especially in rural, off-grid, and sustainable infrastructure projects. How a Gravity-Fed Water System Works At the heart of the system is a basic physical principle: water flows downhill. Water Source a
