The future of water is all about making the most of every drop! That’s why communities around the world are embracing water reuse as a sustainable solution to water challenges.

This illustrated guide turns water reuse concepts into simple explanations that everyone can understand, helping you build public support for resilient water solutions. Because when it comes to water, knowledge is power, and understanding water reuse is as easy as…

Aquifers are nature’s underground water storage system. Think of them as Earth’s water savings account—we can deposit treated water here for future use!

In places where these underground spaces have been overdrawn, purified recycled water is used to replenish them through a process called indirect potable reuse.

Despite its $10 billion industry status, bottled water’s success relies heavily on marketing that harms public confidence in tap water.

Here’s the surprising truth: U.S. tap water often faces stricter oversight than bottled water, with the Environmental Protection Agency (EPA) and state regulators enforcing comprehensive quality standards.

When evaluating water reuse investments, we must look beyond direct costs to see the bigger picture. While communities once relied on relatively inexpensive water resources, those days are fading. New water supplies often require massive infrastructure projects, like cross-state pipelines or coastal desalination plants, driving costs higher and higher.

What’s the true value of water reuse? It’s best measured in thriving businesses, stable property values, and communities confident in their water supplies.
