With back-to-school season upon us, it’s the perfect time to think about how sustainability is taught in classrooms. The usual suspects come to mind—recycling programs, school gardens, maybe even solar panels on the roof. But one critical piece of the sustainability puzzle is often overlooked: wastewater education.

At Waste Management Pros of the Southeast, we believe sustainability isn’t complete without a solid understanding of what happens after water goes down the drain. Teaching students how wastewater is collected, treated, and safely returned to the environment isn’t just science—it’s a lesson in how communities function.

So how can schools start integrating wastewater education into their curriculums?

Wastewater 101: What Do Kids Need to Know?

Let’s start with the basics. Wastewater is any water that has been used and needs treating before it’s released back into nature—think sinks, showers, dishwashers, and, yes, toilets. It also includes runoff from schools, businesses, and even storm drains, all of which require careful treatment to protect public health, waterways, and the environment.

Here’s what a school-friendly curriculum could include:

• The Water Cycle + Human Impact: Teach how natural water movement is altered by urban life.
• What Happens After the Flush: A kid-friendly look at septic systems and treatment plants.
• Pollution + Prevention: Explore how chemicals, wipes, and oils harm water systems.
• Local Field Trips: Visit a local wastewater treatment facility or constructed wetland to learn about and see the processes in action.
• Science Projects: Model mini treatment systems or test water quality samples.

The Classroom Connection

Wastewater education doesn’t need its own class. It blends easily into:

• Science (Biology, Chemistry, Earth Science) – understanding bacteria, filtration, and ecosystems.
• Geography/Environmental Studies – how wastewater management impacts local regions.
• Civics – learning about municipal services and community roles.
• Career Days & STEM Events – showcasing opportunities in wastewater engineering, biology, and plant operations.

Pro Tip: Pair the lesson with real-world data from local water treatment plants or invite a guest speaker to share how treatment facilities keep communities safe and clean.

 Wetlands at Work: What Tres Rios Teaches Us

A powerful teaching tool is showing students a working example of nature and engineering combined—and the Tres Rios Constructed Wetlands Project in Phoenix, Arizona is a gold standard.

Once a wastewater discharge site, Tres Rios has been transformed into a lush wetland that:

• Treats reclaimed water naturally
• Provides habitat for over 150 species of birds
• Offers public trails and educational programs.

Curious how constructed wetlands work and why they’re a smart, sustainable part of wastewater education? Imagine your students watching water go from murky to crystal clear, all thanks to plants, microbes, and gravity—no textbooks needed.

Don’t Let Waste Go to Waste!

Wastewater education might not be glamorous, but it’s essential—and it’s packed with real-world learning opportunities. At Waste Management Pros of the Southeast, we believe that knowledge and action go hand in hand. That’s why we proudly partner with schools, municipalities, and communities across the Southeast to tackle wastewater challenges head-on. 

From engineering and construction to system monitoring and maintenance, we ensure the facilities behind our schools run safely, sustainably, and efficiently. Because when students understand how these systems work, they’re better equipped to care for them—and we’re proud to support both the learning and the infrastructure that makes it possible.
