How Water Towers Work: A Look at the Iconic Idaho Falls Water Tower

Water towers are a common sight across American towns and cities, but few people truly understand how they work. In Southeast Idaho, the Idaho Falls water tower is not only a functional piece of infrastructure but also a local landmark. This post explores the mechanics behind water towers and highlights the unique story of the Idaho Falls structure.

What Is a Water Tower and How Does It Work?

A water tower is essentially a large, elevated storage tank that uses gravity to provide water pressure to homes and businesses. The tower is filled with potable water, usually pumped up from ground-level reservoirs or treatment facilities during low-demand periods (like overnight). When demand increases, the tower releases water through the municipal system.

The Role of Gravity

Water towers rely on gravity to generate pressure. The higher the tower, the greater the pressure delivered to the distribution system below. For every foot of height, roughly 0.43 psi (pounds per square inch) of pressure is produced. A tower 120 feet tall can deliver about 50 psi—ideal for most residential plumbing systems.

Emergency Water Storage

Water towers also serve as emergency storage. In the event of a power outage, natural disaster, or unexpected surge in demand, the water stored in the tower can sustain the system's operation for several hours or more, depending on usage and capacity.

The Idaho Falls Water Tower: A Local Icon

Built in 1937 and standing approximately 125 feet tall, the Idaho Falls water tower has become an emblem of the city. Located near downtown, it was originally constructed to provide both fire protection and reliable water pressure to a growing population.

Design and Engineering

The Idaho Falls water tower is an elevated steel tank supported by a lattice of steel beams. Its elevated design ensures that neighborhoods across the city maintain consistent pressure, especially in higher elevation areas or during peak usage times.

Historic and Community Value

While many cities have replaced older water towers with more modern infrastructure, Idaho Falls has preserved its tower due to its historical significance. It represents early 20th-century engineering and is a recognizable fixture in the city skyline. Locals often refer to it when giving directions or sharing stories about the city’s development.

Why Water Tower Maintenance Matters for Homebuyers

Water infrastructure—including water towers—plays a crucial role in home health and safety. Consistent water pressure, reliable supply, and emergency readiness all contribute to a property's value and livability. At Vantage Point Inspections, we assess a home’s plumbing and water systems as part of our comprehensive home inspection services in Southeast Idaho.

While we don’t inspect the tower itself, we evaluate how effectively a home connects to city water, including pressure checks, potential pipe corrosion, and signs of leaks. Knowing how water gets to your home is just as important as knowing what happens once it gets there.
